Role of Commercial Banks

by

Role of Commercial Banks

A Commercial bank is a type of financial institution that provides services such as accepting deposits, making business loans, and offering basic investment products

There is acute shortage of capital. People lack initiative and enterprise. Means of transport are undeveloped. Industry is depressed. The commercial banks help in overcoming these obstacles and promoting economic development. The role of a commercial bank in a developing country is discussed as under.

  1. Mobilising Saving for Capital Formation:

The commercial banks help in mobilising savings through network of branch banking. People in developing countries have low incomes but the banks induce them to save by introducing variety of deposit schemes to suit the needs of individual depositors. They also mobilise idle savings of the few rich. By mobilising savings, the banks channelize them into productive investments. Thus they help in the capital formation of a developing country.

  1. Financing Industry:

The commercial banks finance the industrial sector in a number of ways. They provide short-term, medium-term and long-term loans to industry.

  1. Financing Trade:

The commercial banks help in financing both internal and external trade. The banks provide loans to retailers and wholesalers to stock goods in which they deal. They also help in the movement of goods from one place to another by providing all types of facilities such as discounting and accepting bills of exchange, providing overdraft facilities, issuing drafts, etc. Moreover, they finance both exports and imports of developing countries by providing foreign exchange facilities to importers and exporters of goods.

  1. Financing Agriculture:

The commercial banks help the large agricultural sector in developing countries in a number of ways. They provide loans to traders in agricultural commodities. They open a network of branches in rural areas to provide agricultural credit. They provide finance directly to agriculturists for the marketing of their produce, for the modernisation and mechanisation of their farms, for providing irrigation facilities, for developing land, etc.

They also provide financial assistance for animal husbandry, dairy farming, sheep breeding, poultry farming, pisciculture and horticulture. The small and marginal farmers and landless agricultural workers, artisans and petty shopkeepers in rural areas are provided financial assistance through the regional rural banks in India. These regional rural banks operate under a commercial bank. Thus the commercial banks meet the credit requirements of all types of rural people. In India agricultural loans are kept in priority sector landing.

  1. Financing Consumer Activities:

People in underdeveloped countries being poor and having low incomes do not possess sufficient financial resources to buy durable consumer goods. The commercial banks advance loans to consumers for the purchase of such items as houses, scooters, fans, refrigerators, etc. In this way, they also help in raising the standard of living of the people in developing countries by providing loans for consumptive activities and also increase the demand in the economy.

  1. Financing Employment Generating Activities:

The commercial banks finance employment generating activities in developing countries. They provide loans for the education of young person’s studying in engineering, medical and other vocational institutes of higher learning. They advance loans to young entrepreneurs, medical and engineering graduates, and other technically trained persons in establishing their own business. Such loan facilities are being provided by a number of commercial banks in India. Thus the banks not only help inhuman capital formation but also in increasing entrepreneurial activities in developing countries.

  1. Help in Monetary Policy:

The commercial banks help the economic development of a country by faithfully following the monetary policy of the central bank. In fact, the central bank depends upon the commercial banks for the success of its policy of monetary management in keeping with requirements of a developing economy.

Issue of NPA

A non performing asset (NPA) is a loan or advance for which the principal or interest payment remained overdue for a period of 90 days.According to RBI, terms loans on which interest or installment of principal remain overdue for a period of more than 90 days from the end of a particular quarter is called a Non-performing Asset.

However, in terms of Agriculture / Farm Loans; the NPA is defined as under:

  • For short duration crop agriculture loans such as paddy, Jowar, Bajra etc. if the loan (installment / interest) is not paid for 2 crop seasons , it would be termed as a NPA.
  • For Long Duration Crops, the above would be 1 Crop season from the due date.

The Securitization and Reconstruction of Financial Assets and Enforcement of Security Interest (SARFAESI) Act has provisions for the banks to take legal recourse to recover their dues. When a borrower makes any default in repayment and his account is classified as NPA; the secured creditor has to issue notice to the borrower giving him 60 days to pay his dues. If the dues are not paid, the bank can take possession of the assets and can also give it on lease or sell it; as per provisions of the SAFAESI Act.

Reselling of NPAs :- If a bad loan remains NPA for at least two years, the bank can also resale the same to the Asset Reconstruction Companies such as Asset Reconstruction Company (India) (ARCIL).  These sales are only on Cash Basis and the purchasing bank/ company would have to keep the accounts for at least 15 months before it sells to other bank. They purchase such loans on low amounts and try to recover as much as possible from the defaulters. Their revenue is difference between the purchased amount and recovered amount

 

Commodity Exchanges in India

Though there are about 25 commodity exchanges in India, the following are the major ones:

 

Multi Commodity Exchange (MCX) – 2003 – Mumbai – MCX COMDEX index

National Commodity and Derivatives Exchange (NCDEX) – 2003 – Mumbai

National Multi-commodity Exchange (NCME) – 2001 – Ahmedabad – first

FUNCTIONS OF MANAGEMENT- DIRECTION (Communication,Supervision,Motivation,Leadership)

by

 

 

 

 

Directing is concerned with instructing, guiding, supervising and inspiring people in the organisation to achieve its objectives. It is the process of telling people what to do and seeing that they do it in the best possiblemanner.

 

Elements in Directing: The four essential elements in Directing are :

 

  1. Communication
  2. Supervision
  3. Motivation
  4. Leadership

 

 

  1. COMMUNICATION

 

Communication is a basic organisational function, which refers to the process by which a person (known as sender) transmits information or messages to another person (known as receiver). The purpose of communication in organisations is to convey orders, instructions, or information so as to bring desired changes in the performance and other attitude of employees. In an organisation, supervisors transmit information to subordinates. Proper communication results in clarity and securing the cooperation of subordinates. Faulty communication may create problems due to misunderstanding between the superior and subordinates. The subordinates must correctly understand the message conveyed to them.

 

Communication Cycle :-

 

Sender—> Message—>Encoding—>Channel/Medium—>Transmission of message—> Receiving & Decoding—>Response & feedback—> Receiver.

 

Classification of Communication :-

 

  • On the basis of Organizational Structure:

 

  • Formal and Informal Communication

The path through which information flows is called channel of communication. In every organisation we have both formal and informal channels. The paths of communication which are based on relationship established formally by management are the formal channels.

For example, The Collector of the district communicates a decision to the SDM who may then issue orders or instructions to the Tahsildaar.

 

Communication, which takes place on the basis of informal or social relations among staff, is   called informal communication.

For example, any sharing of information between a police inspector and an accountant, as they happen to be friends or so. Mostly informal channels are used due to friendly interaction of members of an organisation. In fact, it may be purely personal or related to organisational matters.

 

 

 

  • On the basis of Direction

 

  • Upward: When employees make any request, appeal, report, suggest or communicate ideas to the superior, the flow of communication is upward i.e., from bottom to top. For instance, when a typist drops a suggestion in the suggestion box, or a foreman reports breakdown of machinery to the factory manager, the flow of communication is upward. Upward communication encourages employees to participate actively in the operations of their department. They get encouraged and their sense of responsibility increases when they are heard by their supervisors about problems affecting the jobs.

 

  • Downward: When communication is made from superiors down the hierarchy it is called a downward communication. For instance, when superiors issue orders and instructions to subordinates, it is known as downward communication. When the General Manager orders supervisors to work overtime, the flow of communication is downward i.e., from top to bottom. Similarly, communication of work assignments, notices, requests for performance, etc. through bulletin boards, memos, reports, speeches, meetings, etc, are all forms of downward communication.

 

 

  • Horizontal: Communication can also be amongst members at the same level in the organisation. For instance, production manager may communicate the production plan to the sales manager. This is known as horizontal flow of communication. Here, the communications among people of the same rank and status. Such communication facilitates coordination of activities that are interdependent.

 

  • Diagonal: when communication is not made between people who are in the same department nor at the same level of organisational hierarchy, it is called diagonal communication. For example, cost accountant may request for reports from sales representatives not the sales manager for the purpose of distribution cost analysis. This type of communication does take place under special circumstances.

 

  • On the basis of Mode of Expression

 

  • Verbal and Non verbalCommunication : On the basis of the mode used, communication may be verbal or non-verbal. While communicating, managers may talk to their subordinates either face to face or on telephone or they may send letters, issue notices, or memos. These are all verbal communication. Thus, the verbal modes of communication may be oral and written. Face to face communication, as in interviews, meetings and seminars, are examples of oral communication. Issuing orders and instructions on telephone or through an inter-communication system is also oral communication. The written modes of communication include letters, circulars, notices and memos. Sometimes verbal communication is supported by non-verbal communication such as facial expressions and body gestures. For example – wave of hand, a smile or a frown etc. This is also termed as the gestural communication

 

 

 

 

 

 

 

 

 

 

  1. SUPERVISION

 

It is the duty of the manager to see that they perform the work as per instructions. Managers play the role of supervisors and ensure that the work is done as per the instructions and the plans. Supervisors clarify all instructions and guide employees to work as a team in co-operation with others.

Though supervision is required at all levels of management, it is of great importance at the operational level i.e., at the level of first line supervisor. Managers at this level devote maximum time in supervising the work of subordinates. Though the top or middle level managers also supervise the work of their subordinate managers, but it is the first line supervisors who are in direct and constant touch with operatives i.e., workers in the factory and clerical staff in the office. Thus, they are directly responsible for getting the work done through most of the employees in an organisation.

 

Functions of a Supervisor

 

A supervisor works at the lowest level of management like all other managers he performs the functions of planning, organising, directing and controlling with respect to his own subordinates and department. A major part of his time is devoted in directing and controlling the activities of his subordinates. He also coordinates the activities of his subordinates by integrating the same with the activities of other departments of the enterprise. Besides he performs certain special functions which have been described below:

 

  1. Link between Top Management and Workers: A supervisor works as a link between managers working at higher levels and workers. He conveys the decision of the higher level managers to the workers and also communicates the performance of the workers to the higher level management through different performance reports. He also communicates the grievances, feelings of demands etc. of the workers to the higher level management.

 

  1. Creating Ideal Atmosphere: Being an important link between the operatives and the management a supervisor is expected to create an ideal atmosphere for work in the organisation by correctly communicating the ideas, wishes and decisions of the higher level management to the workers.

 

  1. Guiding the Workers: For obtaining best results the supervisor assigns jobs to the workers keeping in mind their ability and aptitude for work. He makes them available the necessary tools and equipments, raw materials etc. for proper execution of the jobs. He also guides the worker properly to ensure that the job is done with perfection and accuracy.

 

  1. Quality Output : A supervisor has to ensure quality output through constant watch on the performance of workers. He ensures that the performance of the worker takes place as per the plans. This results into study flow of output.

 

  1. Feedback: A supervisor keeps on watching the performance of his subordinates and identifies their strengths and weaknesses. He gives the feedback about this to the workers with the object to further improve the performance of the workers in future.

 

  1. Suggest Training Programmes: A supervisor identifies the areas in which the workers require training and accordingly suggests training programmes that should be organised for them.

 

 

 

  1. MOTIVATION

 

Motivation is one of the important elements of directing.

It is a force that inspires a person at work to intensify his willingness to use the best of his capability for achievement of specified objectives. It may be in the form of incentives like financial (such as bonus, commission etc.) or, non-financial (such as appreciation, growth etc.), or it could be positive or negative. Basically, motivations directed towards goals and prompt people to act.

 

The importance of motivation lies in converting this ability to work into willingness to work. Performance depends on ability as well as willingness; and willingness depends on motivation. Thus, motivation is a key element in directing people to do the job.

 

Each employee has some needs of his own that he wants to fulfil. While directing, it is essential to ensure that any of the unfulfilled need of the individual is being taken care of.

Maslow’s Hierarchy of Needs:-

 

According to Maslow, an individual has many needs and their order can be determined. If a person satisfies his first need, then he thinks about his next need. After satisfying the second need, he tries to satisfy third need and so on. So needs are the motivators. Maslow has given hierarchy of needs in the following ways :

 

  1. Physiological Needs: These needs include need for food, shelter and clothing.

 

  1. 2. Safety and Security Needs: Once physiological needs are fulfilled then the people start thinking about their safety. Safety needs include need for physical safety and economic safety. Physical safety means safety from accidents, disease etc. Economic safety refers to safety of livelihood.

 

  1. Social Needs: Man is a social animal. He wants to live in the society honourably. Therefore, he wants friends and relatives with whom he can share his joys and sorrows. Social needs include need for love, affection, friendship etc.
  2. 4. Esteem Needs: These are the need for respect and recognition. Esteem needs are also known as Ego needs.

 

  1. Self ActualisationNeeds : Self actualisation needs are concerned with becoming what a person is capable of becoming. These needs include need for growth, self-fulfilment etc.

 

 

Financial and Non-financial Hierarchy Theory

 

Monetary / Financial incentives are directly related with money. Non-financial incentives are not directly related with money. Following are the financial incentives:

 

  1. Pay and Allowances: Salary is the basic monetary incentive of every employee. Salary includes basic pay, dearness allowance etc.

 

  1. Bonus: Bonus means the payment to employees in addition to their regular remuneration. Bonus is provided in the form of cash, free trips to resorts or foreign countries etc.

 

  1. Commission: In sales department, sales persons get commission on the basis of their sales.

 

  1. Retirement Benefit: Every employee is concerned about his future after retirement. Some retirement benefits are Provident fund, Pension, Gratuity etc.

 

  1. Perquisites: Rent free accommodation, car allowance, facility of a servant etc.are called as perquisites.

 

Non-financial Incentives: Besides the financial incentives there is certain non financial incentive that motivates the employees. The important non-financial incentive is given below:

 

  1. Career Advancement Opportunity : Appropriate skill development programmes will encourage employees to show improved performance.

 

  1. Status: Status means the rank of a person in a organisation. The rank is linked with authority, responsibility and other extra benefits. Everybody has a wish to be in high rank. Therefore an employee can be motivated by placing him in higher rank.

 

  1. Employee Recognition Programmes: Every employee wants to be considered as an important part of the organisation. Work of an organisation should be distributed in such a way that every employee feels that his work is yield and he is capable to do that work. This motivates the worker and he works hard and in a responsible manner.

 

  1. Employee Participation: It means involving employee in decision making especially when decisions are related to workers.

 

  1. Organisation Climate: It means the relationship between superior and subordinates. Employees can put their best if healthy climate exist in an organisation. It is important to remember that the needs and desires of people change. Once their basic needs are satisfied, other needs arise. Managers have thus, to understand the needs and desires of subordinates and decide how to motivate them. The knowledge of the different types of need enables a manager to adopt different ways to motivate individuals depending upon which need is unsatisfied for the individual. For example, a person whose physiological needs are not fulfilled may be motivated to work with a promise of increase in pay, whereas another person may be motivated if he is given a very challenging job to perform regardless of the pay.

 

 

 

  1. LEADERSHIP

 

Leadership is the process, which influences the people and inspires them to willingly accomplish the organisational objectives. The main purpose of managerial leadership isto gets willing cooperation of the workgroup to achieve the goals.

Leadership is the ability to persuade and motivate others to work in desired way for achieving the goals. Thus, a person who is able to influence others and make them follow his instructions is called a leader.

Leadership and Management are two separate concepts.

Leadership exists in both formal and informal organization but Management operates in formal organization.

 

Leadership Styles :

 

  • Autocratic or Authoritarian Style : 2 types

Pure autocrative or negative Leader : Dictator & makes all decisions by himself.

Benevolent autocrat or Positive Leader : Reward power to influence subordinate and welfare of subordinates.

 

  • Participative Leaders : Decentralise authority, Such leaders involve subordinates in decision-making process.

 

  • Free-rein or Laissez – faire Style : Leaders uses his power very little, gives high degree of freedom to his subordinates in their operation. Aids subordinates in performing their job.

 

 

  • Paternalistic Leadership : It is authoritarian by Nature. Heavily work-centred but has consideration for subordinates.

 

Leadership Qualities: – In order to be successful, a leader must possess certain qualities. A good leader should be professionally competent, intelligent, analytical and he/she should have a sense of fair play, including honesty, sincerity, integrity, and sense of responsibility. He must possess initiative, perseverance, be diligent and realistic in his outlook. He must also be able to communicate his subordinates effectively. Human relation skills are must for any leader. Earlier, it was believed that the success or effectiveness of a leader depends upon his personal traits or characteristics, like physical appearance, intelligence, self-confidence, alertness, and initiative.

RELATIVE SPEEED AND TRAIN QUESTIONS

by

 

Speed has no sense of direction unlike the velocity. Relative speed is the speed of one object as observed from another moving object. Questions on train are the classic examples of relative speed and in all these questions it is assumed that trains move parallel to each other – whether in the same direction or the opposite direction. Thus, we shall see how the relative speed is calculated and using it we come to know the time taken by the trains to cross each other and some other like aspects.

Important Formulas – Problems on Trains

  1. x km/hr = (x×5)/18 m/s

 

  1. y m/s = (y×18)/5 km/hr

 

  1. Speed = distance/time, that is, s = d/t

 

  1. velocity = displacement/time, that is, v = d/t

 

  1. Time taken by a train x meters long to pass a pole or standing man or a post
    = Time taken by the train to travel x meters.

 

  1. Time taken by a train x meters long to pass an object of length y meters

= Time taken by the train to travel (x + y) metres.

 

  1. Suppose two trains or two objects are moving in the same direction at v1 m/s and v2 m/s where v1 > v2,

then their relative speed = (v1 – v2) m/s

 

  1. Suppose two trains or two objects are moving in opposite directions at v1 m/s and v2 m/s ,

then their relative speed = (v1+ v2) m/s

 

  1. Assume two trains of length x metres and y metres are moving in opposite directions at v1 m/s and v2 m/s, Then

The time taken by the trains to cross each other = (x+y) / (v1+v2) seconds

 

  1. Assume two trains of length x metres and y metres are moving in the same direction at at v1 m/s and v2 m/s where v1 > v2, Then

The time taken by the faster train to cross the slower train = (x+y) / (v1-v2) seconds

 

  1. Assume that two trains (objects) start from two points P and Q towards each other at the same time and after crossing they take p and q seconds to reach Q and P respectively. Then,

A’s speed: B’s speed = √q: √p

 

 

Solved Examples

Level 1

1.A train is running at a speed of 40 km/hr and it crosses a post in 18 seconds. What is the length of the train?
A. 190 metres B. 160 metres
C. 200 metres

Answer : Option C

 D. 120 metres

 

Explanation :

Speed of the train, v = 40 km/hr = 40000/3600 m/s = 400/36 m/s

Time taken to cross, t = 18 s

Distance Covered, d = vt = (400/36)× 18 = 200 m

Distance covered is equal to the length of the train = 200 m

2.A train having a length of 240 m passes a post in 24 seconds. How long will it take to pass a platform having a length of 650 m?
A. 120 sec B. 99 s
C. 89 s D. 80 s

 

Answer : Option C

Explanation :

v = 240/24 (where v is the speed of the train) = 10 m/s

t = (240+650)/10 = 89 seconds

3.Two trains having length of 140 m and 160 m long run at the speed of 60 km/hr and 40 km/hr respectively in opposite directions (on parallel tracks). The time which they take to cross each other, is
A. 10.8 s B. 12 s
C. 9.8 s D. 8 s

 

Answer : Option A

Explanation :

Distance = 140+160 = 300 m

Relative speed = 60+40 = 100 km/hr = (100×10)/36 m/s

Time = distance/speed = 300 / (100×10)/36 = 300×36 / 1000 = 3×36/10 = 10.8 s

4.A train moves past a post and a platform 264 m long in 8 seconds and 20 seconds respectively. What is the speed of the train?
A. 79.2 km/hr B. 69 km/hr
C. 74 km/hr D. 61 km/hr

 

Answer : Option A

Explanation :

Let x is the length of the train and v is the speed

Time taken to move the post = 8 s

=> x/v = 8

=> x = 8v — (1)

Time taken to cross the platform 264 m long = 20 s

(x+264)/v = 20

=> x + 264 = 20v —(2)

Substituting equation 1 in equation 2, we get

8v +264 = 20v

=> v = 264/12 = 22 m/s

= 22×36/10 km/hr = 79.2 km/hr

5.Two trains, one from P to Q and the other from Q to P, start simultaneously. After they meet, the trains reach their destinations after 9 hours and 16 hours respectively. The ratio of their speeds is
A. 2 : 3 B. 2 :1
C. 4 : 3 D. 3 : 2

 

Answer : Option C

Explanation :

Ratio of their speeds = Speed of first train : Speed of second train

= √16: √ 9

= 4:3

 6.Train having a length of 270 meter is running at the speed of 120 kmph . It crosses another train running in opposite direction at the speed of 80 kmph in 9 seconds. What is the length of the other train?
A. 320 m B. 190 m
C. 210 m D. 230 m

 

Answer : Option D

Explanation :

Relative speed = 120+80 = 200 kmph = 200×10/36 m/s = 500/9 m/s

time = 9s

Total distance covered = 270 + x where x is the length of other train

(270+x)/9 = 500/9

=> 270+x = 500

=> x = 500-270 = 230 meter

7.Two stations P and Q are 110 km apart on a straight track. One train starts from P at 7 a.m. and travels towards Q at 20 kmph. Another train starts from Q at 8 a.m. and travels towards P at a speed of 25 kmph. At what time will they meet?
A. 10.30 a.m B. 10 a.m.
C. 9.10 a.m. D. 11 a.m.

 

Answer : Option B

Explanation :

Assume both trains meet after x hours after 7 am

Distance covered by train starting from P in x hours = 20x km

Distance covered by train starting from Q in (x-1) hours = 25(x-1)

Total distance = 110

=> 20x + 25(x-1) = 110

=> 45x = 135

=> x= 3 Means, they meet after 3 hours after 7 am, ie, they meet at 10 am

8.Two trains are running in opposite directions in the same speed. The length of each train is 120 meter. If they cross each other in 12 seconds, the speed of each train (in km/hr) is
A. 42 B. 36
C. 28 D. 20

 

Answer : Option B

Explanation :

Distance covered = 120+120 = 240 m

Time = 12 s

Let the speed of each train = v. Then relative speed = v+v = 2v

2v = distance/time = 240/12 = 20 m/s

Speed of each train = v = 20/2 = 10 m/s

= 10×36/10 km/hr = 36 km/hr

 

Level 2

1.A train, 130 meters long travels at a speed of 45 km/hr crosses a bridge in 30 seconds. The length of the bridge is
A. 270 m B. 245 m
C. 235 m D. 220 m

 

Answer : Option B

Explanation :

Assume the length of the bridge = x meter

Total distance covered = 130+x meter

total time taken = 30s

speed = Total distance covered /total time taken = (130+x)/30 m/s

=> 45 × (10/36) = (130+x)/30

=> 45 × 10 × 30 /36 = 130+x

=> 45 × 10 × 10 / 12 = 130+x

=> 15 × 10 × 10 / 4 = 130+x

=> 15 × 25 = 130+x = 375

=> x = 375-130 =245

2.A train has a length of 150 meters. It is passing a man who is moving at 2 km/hr in the same direction of the train, in 3 seconds. Find out the speed of the train.
A. 182 km/hr B. 180 km/hr
C. 152 km/hr D. 169 km/hr

 

Answer : Option A

Explanation :

Length of the train, l = 150m

Speed of the man, Vm= 2 km/hr

Relative speed, Vr = total distance/time = (150/3) m/s = (150/3) × (18/5) = 180 km/hr

Relative Speed = Speed of train, Vt – Speed of man (As both are moving in the same direction)

=> 180 = Vt – 2 => Vt = 180 + 2 = 182 km/hr

3.Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively. If they cross each other in 23 seconds, what is the ratio of their speeds?
A. Insufficient data B. 3 : 1
C. 1 : 3 D. 3 : 2

 

Answer : Option D

Explanation :

Let the speed of the trains be x and y respectively

length of train1 = 27x

length of train2 = 17y

Relative speed= x+ y

Time taken to cross each other = 23 s

=> (27x + 17 y)/(x+y) = 23 => (27x + 17 y)/ = 23(x+y)

=> 4x = 6y => x/y = 6/4 = 3/2

4.A jogger is running at 9 kmph alongside a railway track in 240 meters ahead of the engine of a 120 meters long train . The train is running at 45 kmph in the same direction. How much time does it take for the train to pass the jogger?
A. 46 B. 36
C. 18 D. 22

 

Answer : Option B

Explanation :

Distance to be covered = 240+ 120 = 360 m

Relative speed = 36 km/hr = 36×10/36 = 10 m/s

Time = distance/speed = 360/10 = 36 seconds

5.A train passes a platform in 36 seconds. The same train passes a man standing on the platform in 20 seconds. If the speed of the train is 54 km/hr, The length of the platform is
A. None of these B. 280 meter
C. 240 meter D. 200 meter

 

Answer : Option C

Explanation :

Speed of the train = 54 km/hr = (54×10)/36 m/s = 15 m/s

Length of the train = speed × time taken to cross the man = 15×20 = 300 m

Let the length of the platform = L

Time taken to cross the platform = (300+L)/15

=> (300+L)/15 = 36

=> 300+L = 15×36 = 540 => L = 540-300 = 240 meter

6.A train overtakes two persons who are walking in the same direction to that of the train at 2 kmph and 4 kmph and passes them completely in 9 and 10 seconds respectively. What is the length of the train?
A. 62 m B. 54 m
C. 50 m D. 55 m

 

Answer : Option C

Explanation :

Let x is the length of the train in meter and v is its speed in kmph

x/9 = (v-2) (10/36) — (1)

x/10 = (v-4) (10/36) — (2)

Dividing equation 1 with equation 2

10/9 = (v-2)/(v-4) => 10v – 40 = 9v – 18 => v = 22

Substituting in equation 1, x/9 = 200/36 => x = 9×200/36 = 50 m

7.A train is traveling at 48 kmph. It crosses another train having half of its length, traveling in opposite direction at 42 kmph, in 12 seconds. It also passes a railway platform in 45 seconds. What is the length of the platform?
A. 500 m B. 360 m
C. 480 m D. 400 m

 

Answer : Option D

Explanation :

Speed of train1 = 48 kmph

Let the length of train1 = 2x meter

Speed of train2 = 42 kmph

Length of train 2 = x meter (because it is half of train1’s length)

Distance = 2x + x = 3x

Relative speed= 48+42 = 90 kmph = 90×10/36 m/s = 25 m/s

Time = 12 s

Distance/time = speed => 3x/12 = 25

=> x = 25×12/3 = 100 meter

Length of the first train = 2x = 200 meter

Time taken to cross the platform= 45 s

Speed of train1 = 48 kmph = 480/36 = 40/3 m/s

Distance = 200 + y where y is the length of the platform

=> 200 + y = 45×40/3 = 600

=> y = 400 meter

8.A train, 800 meter long is running with a speed of 78 km/hr. It crosses a tunnel in 1 minute. What is the length of the tunnel (in meters)?
A. 440 m B. 500 m
C. 260 m D. 430 m

 

Answer : Option B

Explanation :

Distance = 800+x meter where x is the length of the tunnel

Time = 1 minute = 60 seconds

Speed = 78 km/hr = 78×10/36 m/s = 130/6 = 65/3 m/s

Distance/time = speed

(800+x)/60 = 65/3 => 800+x = 20×65 = 1300

=> x = 1300 – 800 = 500 meter

9.Two trains are running at 40 km/hr and 20 km/hr respectively in the same direction. If the fast train completely passes a man sitting in the slower train in 5 seconds, the length of the fast train is :
A. 19 m B. 2779 m
C. 1329 m D. 33 m

 

Answer : Option B

Explanation :

Relative speed = 40-20 = 20 km/hr = 200/36 m/s = 100/18 m/s

Time = 5 s

Distance = speed × time = (100/18) × 5 = 500/18 m = 250/9 = 2779 m = length of the fast train

Extent of Mughal Empire at Akbar’s Death

Miscellaneous Facts:

 

1.Muhammad was born in Mecca in 570 AD. The Quran alongwith the Hadith (sayings of the prophet) is venerated as supreme sources of authority in Islam. Muhammad’s migration from Mecca to Medina is known as Hijra & the muslim calendar commences from this year. At the battle of Badr Muhammad first wielded sword to assert his prophethood. Quibla the direction to be faced during prayer changed from Jerusalem to Mecca.

 

2.Prophet’s son-in-law Ali was regarded as lawful immediate by some section (shiis) while other group considered his close followers Abu Bakr, Umar & Uthman as legal heir (came to be known as Sunnis).

 

3.Mahmud of Ghazni was the son of Subuktigin (founder of Ghaznavid dynasty). Subuktgin had defeated the Hindhshahi ruler Jaipal. Utbi was the court historian of Ghazni. Mahmud raided 17 times which

 

 

 

 

 

included Nagarkot, Mathura, Kanauj & Somanath temple (1025 AD when Chalukya king Bhima I was ruling Gujarat). He patronized Al-Beruni.

 

4.Muhammad Ghur first invasion was against Multan which he won easily. His invasion of Gujarat ended in a crushing defeat at the hands of the Chalukyan forces. Then followed Battle of Tarain I & II, invasion of Ghadavala ruled by Jaichandra. After Ghur’s death his senior slave Tajuddin Yalduz occupied Ghazni, Qubacha occupied Multan, Ali Mardan took Lakhnauti (Bihar-Bengal) while Aibak took Delhi. At the same time Bhaktiyar Khalji, another slave raided province of Bihar destroying monasteries of Nalanda & Vikramshila & even attacked the Bengal ruler Lakshmanasena. Eastern Chalukyas ruled at Vengi.

 

5.Chola king Rajendra I captured whole of Sri Lanka & reasserted Chola soverignity over Kerala & Pandyan country. He conquered north upto Ganga & assumed the title of Gangaikonda. Marco Polo visited the Pandyan Kingdom around 1293 AD.

 

6.Muhammad bin Tughlaq’s reign saw the rise of two independent states in south – Vijaynagar & Bahamani. The Tungabhadra doab had been a source of conflict between the Cholas & the western Chalukyas, between Yadavas & Hoysalas as well as between the Vijaynagar & the Bahmani Kindom.

 

7.The largest indigenous industry during the Delhi sultanate period was that of textiles. During Firuz Shah the slaves rose to an all time high. While India’s indigenous architecture is trabeate (space spanned by beams laid horizontally), the Islamic form is arcuate (arches are used to bridge a space).

 

8.All the Lodi rulers were buried on the Bagh-i-Jud known today as Lodi Garden. The coins of Mahmud Ghazni, Iltutmish, Nasirudin Mahmud, Balban, Alauddin Khalji bear the name of Abbasid Caliph.

 

  1. Mansabdars had dual ranks – zat (personal rank & expenses) & sawar (cavalry rank). Land revenue systems were batai (crop divided between state & the peasant), hast-o-bud (official inspection for estimation), kankut system (estimation of land & yield), nasaq system (based on previous estimates).

   TERRESTRIAL ECOSYSTEMS

by

 

 

The interrelations between organisms and environment on the land constitute “Terrestrial Ecology”.

The most important limiting factors of the terrestrial ecosystems are moisture and temperature.

 

 

TUNDRA

The word tundra means a “barren land” since they are found where environmental conditions are very severe. There are two types of tundra- arctic and alpine.

Distribution:

Arctic tundra extends as a continuous belt below the polar ice cap and above the tree line in the northern hemisphere. It occupies the northern fringe of Canada, Alaska, European Russia, Siberia and island group of Arctic Ocean.

On the south pole, tundra is very small since most of it is covered by ocean .

Alpine tundra occurs at high mountains above the tree line. Since mountains are found at all latitudes therefore alpine tundra shows day and night temperature variations.

Flora and fauna:

Typical vegetation of arctic tundra is cotton grass, sedges, dwarf heath, willows, birches and lichens.

Animals of tundra are reindeer, musk ox, arctic hare, caribous, lemmings and squirrel.

They are protected from chillness by the presence of thick cuticle and epidermal hair.

Mammals of the tundra region have large body size and small tail and ear to avoid the loss of heat from the surface.

The body is covered with fur for insulation.

Evolution and characteristics of landforms in the Fluvial, Glacial, Arid and Karst regions  

by

 

Landform

Each landform has its unique physical shape, size, materials and is a result of the action of certain geomorphic processes and agent(s). Every landform has a beginning. Landforms once formed may change in their shape, size and nature slowly or fast due to continued action of geomorphic processes and agents. Due to changes in climatic conditions and vertical or horizontal movements of landmasses, either the intensity of processes or the processes themselves might change leading to new modifications in the landforms.

Evolution

It implies stages of transformation of either a part of the earth’s surface from one landform into another or transformation of individual landforms after they are once formed. That means, each and every landform has a history of development and changes through time. A landmass passes through stages of development somewhat comparable to the stages of life — youth, mature and old age.

Geomorphic Agents

Changes on the surface of the earth owe mostly to erosion by various geomorphic agents. Running water, ground-water, glaciers, wind and waves are powerful    erosional and depositional agents shaping and changing the surface of the earth aided by weathering and mass wasting processes. These geomorphic agents acting over long periods of time produce systematic changes leading to sequential development of landforms.

Fluvial landforms

The landforms created as a result of degradational action (erosion) or aggradation work (deposition) of running water is called fluvial landforms.

These landforms result from the action of surface flow/run-off or stream flow (water flowing through a channel under the influence of gravity). The creative work of fluvial processes may be divided into three physical phases—erosion, transportation and deposition.

The landforms created by a stream can be studied under erosional and depositional categories.

Erosional category

Valleys, gorge and Canyon

The extended depression on ground through which a stream flows throughout its course is called a river valley. A gorge is a deep valley with very steep to straight sides. A canyon is characterized by steep step-like side slopes and may be as deep as a gorge.

At a young stage, The profile of valley  is typically ‘V’ shaped. As the cycle attains maturity, the lateral erosion becomes prominent and the valley floor flattens out. The valley profile now becomes typically ‘U’ shaped with a broad base and a concave slope.

Potholes, Plunge pools

Potholes are more or less circular depressions over the rocky beds of hills streams.Once a small and shallow depression forms, pebbles and boulders get collected in those depressions and get rotated by flowing water. Consequently, the depressions grow in dimensions to form potholes.Plunge pools are nothing but large, deep potholes commonly found at the foot of a waterfall. They are formed because of the sheer impact of water and rotation of boulders.

Incised or Entrenched Meanders

They are very deep wide meanders (loop-like channels) found cut in hard rocks.In the course of time, they deepen and widen to form gorges or canyons in hard rock.The difference between a normal meander and an incised/entrenched meander is that the latter found on hard rocks.

River Terraces

They are surfaces marking old valley floor or flood plains.They are basically the result of vertical erosion by the stream. When the terraces are of the same elevation on either side of the river, they are called as paired terraces.When the terraces are seen only on one side with none on the other or one at quite a different elevation on the other side, they are called as unpaired terraces.

Depositional Features

Alluvial Fans

They are found in the middle course of a river at the foot of slope/ mountains.When the stream moves from the higher level break into foot slope plain of low gradient, it loses its energy needed to transport much of its load.Thus, they get dumped and spread as a broad low to the high cone-shaped deposits called an alluvial fan.

Deltas

They are found in the mouth of the river, which is the final location of depositional activity of a river. \The coarser material settle out first and the finer materials like silt and clay are carried out into the sea.

 

 Flood Plains, Natural Levees

Natural levees are found along the banks of large rivers. They are low, linear and parallel ridges of coarse deposits along the banks of a river.The levee deposits are coarser than the deposits spread by flood water away from the river.

 

 Meanders and oxbow lakes

  • They are formed basically because of three reasons: (i) propensity of water flowing over very gentle gradient to work laterally on the banks; (ii) unconsolidated nature of alluvial deposits making up the bank with many irregularities; (iii) Coriolis force acting on fluid water deflecting it like deflecting the wind.
  • The concave bank of a meander is known as cut-off bank and the convex bank is known as a slip-off
  • As meanders grow into deep loops, the same may get cut-off due to erosion at the inflection point and are left as oxbow lakes.

Braided Channels

When selective deposition of coarser materials causes the formation of a central bar, it diverts the flow of river towards the banks, which increases lateral erosion. Similarly, when more and more such central bars are formed, braided channels are formed. Riverine Islands are the result of braided channels.

 

Karst Topography

Any limestone, dolomite or gypsum region showing typical landforms produced by the action of groundwater through the process of solution and deposition is called as Karst Topography (Karst region in the Balkans).

Sinkholes

A sinkhole is an opening more or less circular at the top and funnel-shaped towards the bottom.When as sinkhole is formed solely through the process of solution, it is called as a solution sink.When several sink holes join together to form valley of sinks, they are called as blind valleys.

 

Caves

In the areas where there are alternative beds of rocks (non-soluble) with limestone or dolomite in between or in areas where limestone are dense, massive and occurring as thick beds, cave formation is prominent. Caves normally have an opening through which cave streams are discharged Caves having an opening at both the ends are called tunnels.

Stalactites and stalagmites

They are formed when the calcium carbonates dissolved in groundwater get deposited once the water evaporates.These structures are commonly found in limestone caves.Stalactites are calcium carbonate deposits hanging as icicles while Stalagmites are calcium carbonate deposits which rise up from the floor.When a stalactite and stalagmite happened to join together, it gives rise to pillars or columns of different diameters.

GLACIERS

Masses of ice moving as sheets over the land (continental glacier or piedmont glacier if a vast sheet of ice is spread over the plains at the foot of mountains) or as linear flows down the slopes of mountains in broad trough-like valleys (mountain and valley glaciers) are called glaciers.

EROSIONAL LANDFORMS

Cirque

Cirques are the most common of landforms in glaciated mountains. They are deep, long and wide troughs or basins with very steep concave to vertically dropping high walls at its head as well as sides. A lake of water can be seen quite often within the cirques after the glacier disappears. Such lakes are called cirque or tarn lakes.

Horns and Serrated Ridges

Horns form through head ward erosion of the cirque walls. If three or more radiating glaciers cut headward until their cirques meet, high, sharp pointed and steep sided peaks called horns form.

 

Glacial Valleys/Troughs

Glaciated valleys are trough-like and U-shaped with broad floors and relatively smooth, and steep sides. There may be lakes gouged out of rocky floor or formed by debris within the valleys. There can be hanging valleys at an elevation on one or both sides of the main glacial valley. Very deep glacial troughs filled with sea water and making up shorelines (in high latitudes) are called fjords/fiords.

 

Depositional landforms

 

Moraines

They are long ridges of deposits of glacial till. Terminal moraines are long ridges of debris deposited at the end (toe) of the glaciers. Lateral moraines form along the sides parallel to the glacial valleys. The lateral moraines may join a terminal moraine forming a horse-shoe shaped ridge. deposits varying greatly in thickness and in surface topography are called ground moraines.

 

Eskers

When glaciers melt in summer, the water flows on the surface of the ice or seeps down along the margins or even moves through holes in the ice. These waters accumulate beneath the glacier and flow like streams in a channel beneath the ice. Such streams flow over the ground (not in a valley cut in the ground) with ice forming its banks. Very coarse materials like boulders and blocks along with some minor fractions of rock debris carried into this stream settle in the valley of ice beneath the glacier and after the ice melts can be found as a sinuous ridge called esker.

Outwash Plains

The plains at the foot of the glacial mountains or beyond the limits of continental ice sheets are covered with glacio-fluvial deposits in the form of broad flat alluvial fans which may join to form outwash plains of gravel, silt, sand and clay.

Drumlins

Drumlins are smooth oval shaped ridge-like features composed mainly of glacial till with some masses of gravel and sand. The long axes of drumlins are parallel to the direction of ice movement. They may measure up to 1 km in length and 30 m or so in height.

 

Arid Landforms

Wind is one of the  dominant agents in hot deserts. The wind action creates a number of interesting erosional and depositional features in the deserts.

 

EROSIONAL LANDFORMS

Pediments and Pediplains

. Gently inclined rocky floors close to the mountains at their foot with or without a thin cover of debris, are called pediments. through parallel retreat of slopes, the pediments extend backwards at the expense of mountain front, and gradually, the mountain gets reduced leaving an inselberg which is a remnant of the mountain. That’s how the high relief in desert areas is reduced to low featureless plains called pediplains.

Playas

Plains are by far the most prominent landforms in the deserts. In times of sufficient water, this plain is covered up by a shallow water body. Such types of shallow lakes are called as playas where water is retained only for short duration due to evaporation and quite often the playas contain good deposition of salts.

. Deflation Hollows and Caves

Weathered mantle from over the rocks or bare soil, gets blown out by persistent movement of wind currents in one direction. This process may create shallow depressions called deflation hollows. Deflation also creates numerous small pits or cavities over rock surfaces. The rock faces suffer impact and abrasion of wind-borne sand and first shallow depressions called blow outs are created, and some of the blow outs become deeper and wider fit to be called caves.

Mushroom, Table and Pedestal Rocks

Many rock-outcrops in the deserts easily susceptible to wind deflation and abrasion are worn out quickly leaving some remnants of resistant rocks polished beautifully in the shape of mushroom with a slender stalk and a broad and rounded pear shaped cap above. Sometimes, the top surface is broad like a table top and quite often, the remnants stand out like pedestals.

Depositional Landforms

When the wind slows or begins to die down, depending upon sizes of grains and their critical velocities, the grains will begin to settle.

Sand Dunes

Dry hot deserts are good places for sand dune formation. Obstacles to initiate dune formation are equally important. There can be a great variety of dune forms Crescent shaped dunes called barchans with the points or wings directed away from wind .Parabolic dunes form when sandy surfaces are partially covered with vegetation. That means parabolic dunes are reversed barchans with wind direction being the same.

Seif is similar to barchan with a small difference. Seif has only one wing or point. Longitudinal dunes form when supply of sand is poor and wind direction is constant. They appear as long ridges of considerable length but low in height. Transverse dunes are aligned perpendicular to wind direction. These dunes form when the wind direction is constant and the source of sand is an elongated feature at right angles to the wind direction.

 

Nagaland planned development

by

Nagaland planned development

Nagaland is one among the north-eastern states in India. It’s deckled on its west and north by Assam, on its east by Myanmar (formerly called Burma), on its north by Arunachal Pradesh, and on its south by Manipur.

Nagaland is one among India’s smallest states, with a complete area of 16,579 sq kilometer. The Naga Hills run through this tiny state that has Saramati as its highest peak at a height of concerning 12,600 ft. Dhansiri, Doyang, Dikhu and Jhanji are the rivers that flow through this state. The piece of land is mountainous, thickly wooded, and cut by deep river valleys. There’s a good variety of plant and animal life. Nagaland features a monsoon climate with usually high humidity; rain averages between 1800 to 2500 millimeter (70 to 100 inches) a year.

Nagaland features a single-chamber legislative assembly with sixty seats. The state sends 2 members to the Indian Parliament: one to the Rajya Sabha (Upper House) and one to the Lok Sabha (Lower House). There are seven government body districts – Mokokchung, Tuensang, Mon, Wokha, Zunheboto, Phek and Kohima.

The state is found between the 93°20′ E and 95°15′ E Longitudes and 25°6′ and 27°4′ N Latitudes. The whole area lined by the state is 16,579 sq. kilometer. Nagaland was declared the sixteenth state of the country of India on 1 December 1963. Before this, Nagaland accustomed is a union territory. The opposite attention-grabbing data about Nagaland is that it homes as several as sixteen totally different ethnic groups. These groups of individuals have their own separate cultural identities that embrace customs, dresses and languages. Nearly 90th of the population of Nagaland is devout Christians. The state conjointly features a substantial Hindu people. Kohima, the capital city of the state, features a range of sites that should be visited by the tourists because it can facilitate them in obtaining an insight of the wealthy history place. The name ‘Kohima’ has been derived from the name of a plant known as ‘Kew Hi’ that thrives within the mountainous region. Kohima is a fascinating place, blessed with lots of natural beauty.

Nagaland particularly, the requirement for infrastructure is important because of rough and mountainous areas on the one hand and sparsely inhabited areas on the opposite. Speedy provision of infrastructure and property becomes important for the economic development of the State.

Roadways

The set up for Integrated, Intensive and comprehensive Agriculture Clusters (IIIACs), urbanization and industrial enterprise in Vision 2030 are all projected to be situated on the ‘Approved’ and ‘Declared Highways’, the Nagaland expressway and also the Trans Frontier Nagaland highway . Thus, these proposals ought to be pursued and enforced with utmost urgency as there are instances of undue delay in implementation of some very important sanctioned comes.

The four-laning of AH1 to Moreh and development of highway property to International Trade centres (ITCs) at Longwa, Pangsha and Avangkhu are regular to be completed within the medium term plan. It’s expected that these can result in growth of the tertiary sector within the fields of IT, trade, hospitality, logistics, education, medical and tending sectors, power transmissions, transit, transport and monetary services. The movements of products and services and passengers to and fro from Nagaland to ASEAN and vice versa can actually create Nagaland the entryway to ASEAN.

Towards this finish, within the deliverables of 2030, the govt. can implement a 2 lane National highway network connecting all the districts. Priority specially are given within the next 5 years to develop the Nagaland expressway from Tizit to Khelma, the Trans-Eastern highway from Mon to Avangkhu and also the four lane highway from Dimapur to Moreh via Kohima (AH1), therefore giving concrete impetus to the Act East Policy.

Further, the road property inside the State are going to be boosted by property with Assam, Arunachal, Manipur, and last however not the smallest amount, the govt.’s priority in conjunction therewith of the Government of India to develop road linkages to Myanmar directly from the known ITCs.

Maintenance: excluding National Highways, the State has over 11000 kms of varied forms of vital roads, which connect districts to sub-divisions, villages and agriculture/ horticulture areas. These roads can need to be maintained by the State public works Department.

In the next 5 years, an amount of Rs. 300 crores each year are going to be needed as per the draft State Repair and Maintenance Policy 2016. Funding for a similar is planned to be from the NLCPR and NEC schemes, excluding States own resources which can need to be mobilized by the govt. for the roads sector.

Rail Network

In pursuit of multi-model connectivity, the set up for the railways is to attach Kohima with the remainder of the country by a railroad track railway line by 2020. The foothills of Nagaland are to be connected with a railway network from Tizit to Dimapur. To reinforce international property within the railways sector, the govt. can propose to create a railway line from Dhansripar in Dimapur district to Karong in Manipur which might logically connect with Moreh and touch lines with the network in Myanamr, thereby making the chance of concretizing the Trans-Asian Railway line by 2025.

Air Connectivity- Intra State Links

In the field of air property, the goals are going to be to shift this airport at Dimapur to Razaphema to accommodate the stress for commerce and product that may emerge because the economy gets developed on the envisaged vision. The new field can need to be created keeping in mind an infrastructure acceptable for a world field and may be in place by 2025, making a transportation hub for national and international carriers.
