Art, Sculpture and Architecture in Kushana Empire

by

 

The Kushana period witnessed a remarkable development in art, sculpture and architecture. The Gandhara School of Art and Sculp­ture marked a happy blending of the Graceo-Romano-Buddhist style and techniques. The distinguishing features of the Gandhara Sculp­ture owed their origin to Greek and Roman styles yet the art essen­tially was Indian in spirit. The Gandhara artists had the hand of a Greek but the heart of an India.

The most remarkable contribu­tion of the Gandhara School of art is to be seen in the evolution of the image of Buddha, perhaps in imitation of the Greek God Apollo. Images of Buddha and Bodhisatva illustrating the past and present lives of Buddha were executed in black stone. The figures show an excellent idea of human anatomy that swayed the artists.

These works of art offer a striking contrast to similar art that we witness else­where in India. The smooth round features of the idealised human figures, draped in transparent and semi-transparent cloth closely fit­ting to the body and revealing its outline were due to the influ­ence of the Hellenistic art of Asia Minor and the Roman Empire.

The images of Buddha pertaining to the Gandhara school cen­tres of which were Gandhara, Jalalabad, Hadda and Baniyan in Afghanistan, Peshawar and Swat Valley, were more animated and anatomically perfect than those found in other parts of India. While the former are more beautiful physically and accurate in anatomical details as such more realistic, the Indian art and sculpture which pro­duced the images of Buddha were more idealistic giving a spiritual and sublime expression to the images.

The technique of the Gan­dhara School of art of the Kushana period spread through China to the Far East and influenced the art of China and Japan. The Gandhara art, according to V. A. Smith, was based on the cosmopolitan art of the Asia Minor and the Roman Empire.

There were also purely Indian schools of art in India during the period of the Kushanas. There were the schools of art at Amaravati, Jagayyapeta and Nagarjunikonda. In the Amaravati human figures are characterised by slim, blithe features and have been repre­sented in most difficult poses and curves. The technique of art reach­ed a high standard of development. Plants and flowers, particularly lotuses, have been represented in the most perfect, lifelike manner.

Two Chaityas and a Stupa discovered at Nagarjunikonda are the relics of the indigenous school of art and show a high standard of development. The limestone panel of figures depicting the nativity of Buddha is an excellent piece of sculpture of the Kushana period which was entirely indigenous.

Architecture of the Kushana period was not so remarkable as the sculpture of the period. There were beautiful temples, monas­teries, Stupas which indicate considerable development during the period although the technique of architecture did not attain the standard of excellence of sculpture. The famous tower of Kanishka at Purushapura (Peshawar) was one of the wonders of the world. Much of the architectural specimens of the period perished with time.

Caves hewn in solid rock with pillars and sculptures, hundreds of which have been found in different parts of the Kushana Empire show a great improvement upon the technique of excavation that was in use during the time of Asoka. A Chaitya with rows of columns on two sides was a fine work of art of sculpture and architecture. The Chaitya at Karle is an excellent illustration.

Fa-hien who visited India during the rule of Chandragupta II {5th century) was struck with wonder to find a large number of Stupas, dagobas (small stupa), Chaityas and images of Buddha carved out of stone during the Kushana period.

There has been a sharp difference of opinion about the celebrity, and the extent of influence of the Gandhara art upon the Indian art during the reign of the Kushanas. Modern scholars think that the Gandhara School of sculpture has attained a celebrity perhaps beyond its merits.

According to some European scholars, the Gandhara School of art was the only school in Ancient India which can claim a place in the domain of art. There are others who are of the opinion that the source of subsequent development of Indian art as well as of the Far East was the Gandhara School of art which developed as a result of a happy blending of the Graco-Romano-Buddhist art.

But despite the foreign influence upon the school of Gandhara art, scholars like Havell, Will Durant, R. C. Majumdar and others are of the opinion that the influence, Hellenistic and Roman, upon the Indian art which was the Gandhara School of art was technical but spirit and the subject matter of the art was purely Indian.

  1. D. Banerjee’s view that the Gandhara art influenced the Indian art for nearly five centuries to follow is untenable on the ground that there were indigenous schools of art at Ainaravati, Nagarjunkonda, etc. where there was no influence of Gandhara School of art. The influence of the Gandhara art failed to penetrate into the interior of India and had no influence on the later development of the Indian, art. But the Gandhara School of art achieved a grand success in. becoming the parent of the Buddhist art of Eastern and Chinese Turkestan, Mongolia, China, Korea and Japan.

Literature:

The Kushana period witnessed a remarkable development of literature and Sanskrit language. Under the patronage enjoyed by the scholars and Buddhist philosophers of the time a massive develop­ment in secular and religious literature took place. A large number of standard works in Sanskrit language were written during the period.

Asvaghosha’s Buddhacharita, Saudarananda Kavya, Vajrasuchi, Sariputta Prakarana, Vasumitra’s Mahabibhasa—regarded as the Bud­dhist encyclopaedia, Nagarjuna’s Madhyamika-Sutra in which the theory of relativity was propounded, Charaka’s work on medicine, etc. contributed to the fund of human knowledge. Under the Kushanas the royal court became a seat of luminaries mentioned above as also of the Political Scientist Mathara, Greek engineer Agesilaus, etc.

On at the present time. School children and college students hold rallies, essay and painting competition etc and unfold the message of renewable Energy and energy conservation. The Ministry has sanctioned Rs.1.50 lakhs to the complete District.

The National Rurban Mission (NRuM) follows the vision of development of a cluster of villages that preserve and nurture the essence of rural community life with target equity and inclusiveness while not compromising with the facilities looked as if it would be primarily urban in nature, therefore making a cluster of “Rurban Villages”. With an objective to stimulate native economic development and enhance basic services, the Union cupboard chaired by the Hon’ble Prime Minister Shri Narendra Modi approved the Shyama Prasad Mukherji Rurban Mission in the year 2015. This formidable bid to remodel rural areas to economically, socially and physically property areas was launched by the Prime Minister in 2016.

 Horizontal and vertical distribution of temperature, inversion of temperature

by

 

The temperature is the measurement in degrees of how hot (or cold) a thing (or a place) is.
The temperature of the atmosphere is not same across the Earth. It varies in spatial and temporal dimensions. The temperature of a place depends largely on the insolation received by that place. The interaction of insolation with the atmosphere and the earth’s surface creates heat which is measured in terms of temperature. It is important to know about the temperature distribution over the surface of the earth to understand the weather, climate, vegetation zones, animal and human life etc. following factors determine the temperature of air at any place.

  1. The latitude of the place – Intensity of insolation depends on the latitude. The amount of insolation depends on the inclination of sun rays, which is further depends upon the latitude of the place. At the equator sun’s rays fall directly overhead throughout the year. Away from the equator towards poles, the inclination of the Sun’s rays increases. In conclusion, if other things remain the same, the temperature of air goes on decreasing from the equator towards poles.
  2. The altitude of the place – the atmosphere is largely heated indirectly by re-radiated terrestrial radiation from the earth’s surface. Therefore, the lower layers of the atmosphere are comparatively warmer than the upper layers, even in the same latitudes. For example, Ambala (30 21’ N) and Shimla (31 6’) are almost at the same latitude. But the average temperature of shimla is much lower than the Ambala. It is because Ambala is located in plain at an altitude of 272 m above sea level whereas Shimla is located at an altitude of 2202 m above sea level. In other words, the temperature generally decreases with increasing height (figure 6(a)). The rate of decrease of temperature with height is termed as the normal lapse rate. It is 6.5°C per 1,000 m. That’s why, the mountains, even in the equatorial region, have snow covered peaks, like Mt. Kilimanjaro, Africa.
  3. Distance from the Sea – the land surface is heated at a faster rate than the water N surface. Thus the temperature of the air over land and water surfaces is not the same Student Notes: at a given time. In summers, the sea water is cooler than the land and in winters, land is much colder than the sea water. The coastal areas experience the sea breezes during the daytime and the land breezes during the night time. This has a moderating influence on the temperature of the coastal areas. Against this the places in the interior, far away from the sea, have extreme climate. The daily range of temperature is less near the coastal area and it increases with increase in distance from the sea coast (figure 6(b)). The low daily range of temperature is the characteristic of marine climate. That’s why, the people of Mumbai have hardly any idea of extremes of temperature.

(a) Horizontal Distribution of Temperature
Distribution of temperature across the latitudes over the surface of the earth is called its horizontal distribution. On maps, the horizontal distribution of temperature is commonly shown by “Isotherms”, lines connecting points that have equal temperatures. An isotherm is made of two words ‘iso’ and ‘therm’, ‘Iso’ means equal and ‘therm’ means” temperature. If you study an isotherm map you will find that the distribution of temperature is uneven. The factors responsible for the uneven distribution of temperature are as follows:
(i) Latitude
(ii) Land and Sea Contrast
(iii) Relief and Altitude
(iv) Ocean Currents
(v) Winds
(vi) Vegetation Cover
(vii) Nature of the soil
(viii) Slope and Aspect

(b) Vertical Distribution of Temperature
The permanent snow on high mountains, even in the tropics, indicate the decrease of temperature with altitute. Observations reveals that there is a fairly regular decrease in temperature with an increase in altitude. The average rate of temperature decrease upward in the troposphere is about 6 C per km, extending to the tropopause. This vertical gradient of temperature is commonly referred to as the standard atmosphere or normal lapse rate, but is varies with height, season, latitude and other factors. Indeed the actual lapse rate of temperature does not always show a decrease with altitude.

Temperature Inversion

Temperature decreases with increase in altitude. In normal conditions, as we go up, temperature decreases with normal lapse rate. It is 6.5°C per 1,000 m. Against this normal rule sometimes, instead of decreasing, temperature may rise with the height gained. The cooler air is nearer the earth and the warmer air is aloft. This rise of temperature with height is known as Temperature inversion. Temperature inversion takes place under certain specific conditions. These are discussed below:

  •  Long winter nights – if in winters the sky is clear during long nights, the terrestrial radiation is accelerated. The reason is that the land surface gets cooled fairly quickly. The bottom layer of atmosphere in contact with the ground is also cooled and the upper layer remains relatively warm.
  • Cloudless clear sky – The clouds obstruct the terrestrial radiation. But this radiation does not face any obstacles for being reflected into space when the sky is clear. Therefore the ground is cooled quickly and so is the air in contact with it cooled.
  • Dry air – humid air absorbs the terrestrial radiation but dry air is no obstruction to terrestrial radiation and allows the radiation to escape into space.
  • Calm atmosphere – the blowing of winds bring warm and cold air into contact. Under conditions of calm atmosphere the cold air stays put near the ground.
  • Ice covered surface – in ice covered areas due to high albedo less insolation is received. During night due to terrestrial radiation most of the heat is lost to atmosphere and the surface is cooled. The air in contact with it is also cooled but the upper layer remains warm.

 

ENVIRONMENT POLLUTION

by

 

defined as ‘an addition or excessive addition of certain materials to the physical environment (water, air and lands), making it less fit or unfit for life’.

Pollutants are the materials or factors, which cause adverse effect on the natural quality of any component of the environment.

Classifications

  1. According to the form in which they persist after release into the environment.
  • Primary pollutants: These persist in the form in which they are added to the environment e.g. DDT, plastic.
  • Secondary Pollutants: These are formed by interaction among the primary pollutants. For example, peroxyacetyl nitrate (PAN) is formed by the interaction of nitrogen oxides and hydrocarbons.
  1. According to their existence in nature.
  • Quantitative Pollutants: These occur in nature and become pollutant when their concentration reaches beyond a threshold level. E.g. carbon dioxide, nitrogen oxide.
  • Qualitative Pollutants: These do not occur in nature and are man-made. E.g. fungicides, herbicides, DDT etc.
  1. According to their nature of disposal.
  • Biodegradable Pollutants: Waste products, which are degraded by microbial action. E.g. sewage.
  • Non-biodegradable Pollutants: Pollutants, which are not decomposed by microbial action. E.g. plastics, glass, DDT, salts of heavy metals, radioactive substances etc
  1. According to origin
  • Natural
  • Anthropogenic

 

AIR POLLUTION

aggravated because of four developments:

Increasing traffic, growing cities, rapid economic development, and industrialization

contamination of air by the discharge of harmful substances

 

Major air pollutants and their sources

  1. Carbon monoxide (CO)
  • It is a colourless, odourless gas that is produced by the incomplete burning of carbon – based fuels including petrol, diesel, and wood.
  • It is also produced from the combustion of natural and synthetic products such as cigarettes.
  • It lowers the amount of oxygen that enters our blood. It can slow our reflexes and make us confused and sleepy.
  1. Carbon dioxide (CO2)

principle greenhouse gas

  1. Chloroflorocarbons (CFC)
  • gases that are released mainly fromair-conditioning systems and refrigeration.
  • When released into the air, CFCs rise to the stratosphere, where they come in contact with few other gases, which lead to a reduction of the ozone layer that protects the earth from the harmful ultraviolet rays of the sun.

 

  1. Lead

present in petrol, diesel, lead batteries, paints, hair dye products, etc.

affects children in particular. cause nervous system damage and digestive problems and, in some cases, cause cancer.

 

  1. Ozone
  • occurs naturally in the upper layers of the atmosphere.
  • at-the ground level, it is a pollutant with highly toxic effects.
  • Vehicles and industries are the major source of ground-level ozone emissions.
  • Ozone makes our eyes itch, burn, and water. It lowers our resistance to cold and pneumonia.

 

  1. Nitrogen oxide (Nox)
  • causes smog and acid rain. It is produced from burning fuels including petrol, diesel, and coal.
  • Nitrogen oxide can make children susceptible to respiratory diseases in winters.

 

  1. Suspended particulate matter (SPM)
  • consists of solids in the air in the form of smoke, dust, and vapour that can remain suspended for extended periods
  • The finer of these particles when breathed in can lodge in our lungs and cause lung damage and respiratory problems.

 

  1. Sulphur dioxide (S02)
  • a gas produced from burning coal, mainly in thermal power plants.
  • Some industrial processes, such as production of paper and smelting of metals, produce sulphur dioxide.
  • a major contributor to smog and acid rain.
  • Sulphur dioxide can lead to lung diseases

 

  1. Smog
  • a combination of the words fog and smoke. Smog is a condition of fog that had soot or smoke in it.
  • interaction of sunlight with certain chemicals in the atmosphere.
  • primary components of photochemical smog is ozone.
  • Ozone is formed through a complex reaction involving hydrocarbons, nitrogen oxides, and sunlight. It is formed when pollutants released from gasoline, diesel- powered vehicles and oil-based solvents react with heat and sunlight from biofuels, the four most serious pollutants are particulates, carbon monoxide, polycyclic organic matter, and formaldehyde

 

Pollutants

  1. i) Volatile organic compounds

The main indoor sources are perfumes, hair sprays, furniture polish, glues, air

fresheners, moth repellents, wood preservatives, and other products.

 

  1. ii) Biological pollutants

It includes pollen from plants, mite, and hair from pets, fungi, parasites, and some bacteria.

iii) Formaldehyde

Mainly from carpets, particle boards, and insulation foam. It causes irritation to the eyes and nose and allergies.

  1. iv) Radon

It is a gas that is emitted naturally by the soil. Due to modern houses having poor ventilation, it is confined inside the house and causes lung cancers.

 

Fly Ash

Ash is produced whenever combustion of solid material takes place.

Composition

  1. Aluminium silicate (in.large amounts)
  2. silicon dioxide (Si02) and
  3. Calcium oxide (Ca0).

Fly ash particles are oxide rich and consist of silica, alumina, oxides of iron, calcium, and magnesium and toxic heavy metals like lead, arsenic, cobalt, and coppers

 

Policy measures of MoEF:

  • The Ministry of Environment and Forests vide its notification in 2009, has made it mandatory to use Fly Ash based products in all construction projects, road embankment works and low lying land filling works within 100 kms radius of Thermal Power Station.
  • To use Fly Ash in mine filling activities within 50 kms radius of Thermal Power Stations.
  • Arresters: These are used to separate particulate matters from contaminated air.
  • Scrubbers: These are used to clean air for both dusts and gases by passing it through a dry or wet packing material.

Government Initiatives

(1) National Air Quality Monitoring Programme

In India, the Central Pollution Control Board (CPCB) has been executing a nationwide programme of ambient air quality monitoring known as National Air Quality Monitoring

Programme (NAMP).

The National Air Quality Monitoring Programme (NAMP) is undertaken in India

(i) to determine status and trends of ambient air quality;

(ii) to ascertain the compliance of NAAQS;

(iii) to identify non-attainment cities;

(iv) to understand the natural process of cleaning in the atmosphere; and

(v) to undertake preventive and corrective measures.

Annual average concentration of SOx levels are within the prescribed National Ambient

Air Quality Standards (NAAQS).

National Ambient Air Quality Standards (NAAQS) were notified in the year 1982, duly revised in 1994 based on health criteria and land uses .

The NAAQS have been revisited and revised in November 2009 for 12 pollutants, which include. sulphur dioxide (S02), nitrogen dioxide (NO2), particulate matter having size less than 10 micron

(PM10),particulate matter having size less than 2.5micron (PM2.5), ozone, lead, carbon monoxide (CO), arsenic, nickel, benzene, ammonia, and. Benzopyrene.

WATER POLLUTION

Addition of certain substances to the water such as organic, inorganic,

biological, radiological, heat, which degrades the quality of water so that it

becomes unfit for use.

Putrescibility is the process of decomposition of organic matter present in water by microorganisms using oxygen.

Water having DO (dissolved oxygen)  content below 8.0 mg/L may be

considered as contaminated.  Water having DO content below. 4.0 mg/L is

considered to be highly polluted.

Water pollution by organic wastes is measured in terms of Biochemical Oxygen Demand-(BOD). BOD is the amount of dissolved oxygen needed by bacteria in decomposing the organic wastes present in water.

Chemical oxygen demand (COD) is a slightly better mode used to measure pollution load in water. It is the measure of oxygen equivalent of the requirement of oxidation of total organic matter (i.e. biodegradable and non- biodegradable) present in water.

A cripling deformity called Minamata disease due to consumption of fish captured from mercury contaminated Minamata Bay.

Water contaminated with cadmium can cause itai itai disease also called ouch-ouch disease (a painful disease of bones and joints) and cancer of lungs and liver.

The compounds of lead cause anaemia, headache, loss of muscle power and bluish line around the gum

Excess nitrate in drinking water reacts with hemoglobin to form non -functional met haemoglobin, and impairs oxygen transport.  This condition  is  called methaemoglobinemia or blue baby syndrome.

Over exploitation of ground water may lead to leaching of arsenic from soil and rock sources and contaminate ground water.  Chronic exposure to arsenic causes black foot disease. It also causes diarrhoea,-peripheral neuritis, hyperkerotosis and also   lung and skin cancer.

SOIL POLLUTION

Industrial waste includes chemicals such as mercury, lead, copper, zinc, cadmium, cynides, thiocynates, chromates, acids, alkalies, organic substances etc

Four R’s: Refuse, Reduce, Reuse, and Recycle

NOISE POLLUTION

Sound is measured in decibels (dB). An increase of about 10 dB is approximately double the increase in loudness.

A person’s hearing can be damaged if exposed to noise levels over 75 dB over a prolonged period of time.

The World Health Organization recommends that the sound level indoors should be less than 30 dB.

Ambient Noise Level Monitoring –   Noise Pollution (Control and Regulation) Rules, 2000 define ambient noise levels for various areas as follows-

  1. Industrial Area—75DB to 70Db (Day time-6am to 10pm and night time 10pm to 6am ..75 is day time and 70 is night time)
  2. Commercial Area–65 to 55
  3. Residential Area–55 to 45
  4. Silence Zone– 50  to 40
  • The Government of India on Mar 2011 launched a Real time Ambient Noise Monitoring Network.
  • Under this network, in phase- I, five Remote Noise Monitoring Terminals each have been installed in different noise zones in seven metros (Delhi, Hyderabad, Kolkata, Mumbai, Bangalore, Chennai and Lucknow).

In Phase II another 35 monitoring stations will be installed in the same seven cities.

Phase III will cover installing 90 stations in 18 other cities.

Phase-III cities are Kanpur, Pune, Surat, Ahmedabad,  Nagpur, Jaipur,  Indore,

Bhopal, Ludhiana, Guwahati, Dehradun, Thiruvananthpuram, Bhubaneswar,

Patna, Gandhinagar, Ranchi, Amritsar and Raipur.

Silence Zone is an area comprising not less than 100 metres around hospitals, educational institutions, courts, religious places or any other t area declared as such by a competent authority.

 

 

RADIO ACTIVE POLLUTION

Non-ionising radiations affect only those components which absorb them and have low penetrability.   They include short-wave radiations such as ultraviolet rays, which forms a part of solar radiation. Sunburns is due to these radiation Ionising radiations have high penetration power & cause breakage of macro molecules

They include X-rays, cosmic rays and atomic radiations -(radiations emitted by radioactive elements

Alpha particles, can be blocked by a piece of paper and human skin.

Beta particles can penetrate through skin, while can be blocked by some pieces of glass and metal.

Gamma rays can penetrate easily to human skin and damage cells on its way through, reaching far, and can only be blocked by a very thick, strong, massive piece of concrete radium-224, uranium-238, thorium-232, potassium-40, carbon-14, etc.

The nuclear arms use uranium-235 and plutonium-239 for fission and hydrogen or lithium as fusion material

The radio nuclides with long half-time are the chief source of environmental radioactive pollution.

BOAT AND STREAM

by

 

Boat and stream problems is a sub-set of time, speed and distance type questions where in relative speed takes the foremost role. We always find several questions related to the above concept in SSC common graduate level exam as well as in bank PO exam. Upon listing the brief theory of the issue below we move to the various kinds of problems asked in the competitive examination.

Important Formulas – Boats and Streams

  • Downstream
    In running/moving water, the direction along the stream is called downstream.
  • Upstream
    In running/moving water, the direction against the stream is called upstream.

 

  • Let the speed of a boat in still water be u km/hr and the speed of the stream be v km/hr, then

    Speed downstream = (u+v) km/hr
    Speed upstream = (u – v) km/hr

 

  • Let the speed downstream be a km/hr and the speed upstream be b km/hr, then

    Speed in still water =1/2*(a+b)km/hr
    Rate of stream = 1/2*(a−b) km/hr

Some more short-cut methods

  • Assume that a man can row at the speed of x km/hr in still water and he rows the same distance up and down in a stream which flows at a rate of y km/hr. Then his average speed throughout the journey

    = (Speed downstream × Speed upstream)/Speed in still water=((x+y)(x−y))/xkm/hr

 

  • Let the speed of a man in still water be x km/hr and the speed of a stream be y km/hr. If he takes t hours more in upstream than to go downstream for the same distance, the distance

    =((x* x –y* y)*t)/2ykm

 

  • A man rows a certain distance downstream in t1 hours and returns the same distance upstream in t2 If the speed of the stream is y km/hr, then the speed of the man in still water

    =y((t2+t1) / (t2−t1)) km/hr

 

  • A man can row a boat in still water at x km/hr. In a stream flowing at y km/hr, if it takes him t hours to row a place and come back, then the distance between the two places

    =t((x* x –y* y))/2xkm

 

  • A man takes n times as long to row upstream as to row downstream the river. If the speed of the man is x km/hr and the speed of the stream is y km/hr, then

    x=y*((n+1)/(n−1))

 

 

Solved Examples

 

Level 1

 

1. A man’s speed with the current is 15 km/hr and the speed of the current is 2.5 km/hr. The man’s speed against the current is:
A. 8.5 km/hr B. 10 km/hr.
C. 12.5 km/hr D. 9 km/hr

 

Answer : Option B

Explanation :

Man’s speed with the current = 15 km/hr

=>speed of the man + speed of the current = 15 km/hr

speed of the current is 2.5 km/hr

Hence, speed of the man = 15 – 2.5 = 12.5 km/hr

man’s speed against the current = speed of the man – speed of the current

= 12.5 – 2.5 = 10 km/hr

2. In one hour, a boat goes 14 km/hr along the stream and 8 km/hr against the stream. The speed of the boat in still water (in km/hr) is:
A. 12 km/hr B. 11 km/hr
C. 10 km/hr D. 8 km/hr

 

Answer : Option B

Explanation :

Let the speed downstream be a km/hr and the speed upstream be b km/hr, then

Speed in still water =1/2(a+b) km/hr and Rate of stream =1/2(a−b) km/hr
Speed in still water = 1/2(14+8) kmph = 11 kmph.

3. A boatman goes 2 km against the current of the stream in 2 hour and goes 1 km along the current in 20 minutes. How long will it take to go 5 km in stationary water?
A. 2 hr 30 min B. 2 hr
C. 4 hr D. 1 hr 15 min

 

Answer : Option A

Explanation :

Speed upstream = 2/2=1 km/hr

Speed downstream = 1/(20/60)=3 km/hr

Speed in still water = 1/2(3+1)=2 km/hr

Time taken to travel 5 km in still water = 5/2= 2 hour 30 minutes

4. Speed of a boat in standing water is 14 kmph and the speed of the stream is 1.2 kmph. A man rows to a place at a distance of 4864 km and comes back to the starting point. The total time taken by him is:
A. 700 hours B. 350 hours
C. 1400 hours D. 1010 hours

 

Answer : Option A

Explanation :

Speed downstream = (14 + 1.2) = 15.2 kmph

Speed upstream = (14 – 1.2) = 12.8 kmph

Total time taken = 4864/15.2+4864/12.8 = 320 + 380 = 700 hours

  

 

5. The speed of a boat in still water in 22 km/hr and the rate of current is 4 km/hr. The distance travelled downstream in 24 minutes is:
A. 9.4 km B. 10.2 km
C. 10.4 km D. 9.2 km

 

   

Answer : Option C

Explanation :

Speed downstream = (22 + 4) = 26 kmph

Time = 24 minutes = 24/60 hour = 2/5 hour

distance travelled = Time × speed = (2/5)×26 = 10.4 km

6. A boat covers a certain distance downstream in 1 hour, while it comes back in 11⁄2 hours. If the speed of the stream be 3 kmph, what is the speed of the boat in still water?
A. 14 kmph B. 15 kmph
C. 13 kmph D. 12 kmph

 

Answer : Option B

Explanation :

Let the speed of the boat in still water = x kmph

Given that speed of the stream = 3 kmph

Speed downstream = (x+3) kmph

Speed upstream = (x-3) kmph

He travels a certain distance downstream in 1 hour and come back in 11⁄2 hour.

ie, distance travelled downstream in 1 hour = distance travelled upstream in 11⁄2 hour

since distance = speed × time, we have

(x+3)×1=(x−3)*3/2

=> 2(x + 3) = 3(x-3)

=> 2x + 6 = 3x – 9

=> x = 6+9 = 15 kmph

7. A boat can travel with a speed of 22 km/hr in still water. If the speed of the stream is 5 km/hr, find the time taken by the boat to go 54 km downstream
A. 5 hours B. 4 hours
C. 3 hours D. 2 hours

 

Answer : Option D

Explanation :

Speed of the boat in still water = 22 km/hr

speed of the stream = 5 km/hr

Speed downstream = (22+5) = 27 km/hr

Distance travelled downstream = 54 km

Time taken = distance/speed=54/27 = 2 hours

 

8. A boat running downstream covers a distance of 22 km in 4 hours while for covering the same distance upstream, it takes 5 hours. What is the speed of the boat in still water?
A. 5 kmph B. 4.95 kmph
C. 4.75 kmph D. 4.65

 

Answer : Option B

Explanation :

Speed downstream = 22/4 = 5.5 kmph

Speed upstream = 22/5 = 4.4 kmph

Speed of the boat in still water = (½) x (5.5+4.42) = 4.95 kmph

9. A man takes twice as long to row a distance against the stream as to row the same distance in favor of the stream. The ratio of the speed of the boat (in still water) and the stream is:
A. 3 : 1 B. 1 : 3
C. 1 : 2 D. 2 : 1

 

Answer : Option A

Explanation :

Let speed upstream = x

Then, speed downstream = 2x

Speed in still water = (2x+x)2=3x/2

Speed of the stream = (2x−x)2=x/2

Speed of boat in still water: Speed of the stream = 3x/2:x/2 = 3 : 1

 

Level  2

1. A motorboat, whose speed in 15 km/hr in still water goes 30 km downstream and comes back in a total of 4 hours 30 minutes. The speed of the stream (in km/hr) is:
A. 10 B. 6
C. 5 D. 4

 

   

Answer : Option C

Explanation :

Speed of the motor boat = 15 km/hr

Let speed of the stream = v

Speed downstream = (15+v) km/hr

Speed upstream = (15-v) km/hr

Time taken downstream = 30/(15+v)

Time taken upstream = 30/(15−v)

total time = 30/(15+v)+30/(15−v)

It is given that total time is 4 hours 30 minutes = 4.5 hour = 9/2 hour

i.e., 30/(15+v)+30/(15−v)=9/2

⇒1(15+v)+1(15−v)=(9/2)×30=3/20

⇒(15−v+15+v)/(15+v)(15−v)=3/20

⇒30/(15*15−v*v)=3/20

⇒30/(225−v*v)=3/20

⇒10/(225−v* v)=1/20

⇒225−v* v =200

⇒v* v =225−200=25

⇒v=5 km/hr

2. A man rows to a place 48 km distant and come back in 14 hours. He finds that he can row 4 km with the stream in the same time as 3 km against the stream. The rate of the stream is:
A. 1 km/hr. B. 2 km/hr.
C. 1.5 km/hr. D. 2.5 km/hr.

 

Answer : Option A

Explanation :

Assume that he moves 4 km downstream in x hours

Then, speed downstream = distance/time=4/x km/hr

Given that he can row 4 km with the stream in the same time as 3 km against the stream

i.e., speed upstream = 3/4of speed downstream=> speed upstream = 3/x km/hr

He rows to a place 48 km distant and come back in 14 hours

=>48/(4/x)+48/(3/x)=14

==>12x+16x=14

=>6x+8x=7

=>14x=7

=>x=1/2

Hence, speed downstream = 4/x=4/(1/2) = 8 km/hr

speed upstream = 3/x=3/(1/2) = 6 km/hr

Now we can use the below formula to find the rate of the stream

Let the speed downstream be a km/hr and the speed upstream be b km/hr, then

Speed in still water =1/2*(a+b) km/hr

Rate of stream =12*(a−b) km/hr
Hence, rate of the stream = ½*(8−6)=1 km/hr

 

3. A boat running upstream takes 8 hours 48 minutes to cover a certain distance, while it takes 4 hours to cover the same distance running downstream. What is the ratio between the speed of the boat and speed of the water current respectively?
A. 5 : 6 B. 6 : 5
C. 8 : 3 D. 3 : 8

 

Answer : Option C

Explanation :

Let the rate upstream of the boat = x kmph

and the rate downstream of the boat = y kmph

Distance travelled upstream in 8 hrs 48 min = Distance travelled downstream in 4 hrs.

Since distance = speed × time, we have

x×(8*4/5)=y×4

x×(44/5)=y×4

x×(11/5)=y— (equation 1)

Now consider the formula given below

Let the speed downstream be a km/hr and the speed upstream be b km/hr, then

Speed in still water =1/2(a+b) km/hr

Rate of stream =1/2(a−b) km/hr
Hence, speed of the boat = (y+x)/2

speed of the water = (y−x)/2

Required Ratio = (y+x)/2:(y−x)/2=(y+x):(y−x)=(11x/5+x):(11x/5−x)

(Substituted the value of y from equation 1)

=(11x+5x):(11x−5x)=16x:6x=8:3

 

4. A man can row at 5 kmph in still water. If the velocity of current is 1 kmph and it takes him 1 hour to row to a place and come back, how far is the place?
A. 3.2 km B. 3 km
C. 2.4 km D. 3.6 km

 

Answer : Option C

Explanation :

Speed in still water = 5 kmph
Speed of the current = 1 kmph

Speed downstream = (5+1) = 6 kmph
Speed upstream = (5-1) = 4 kmph

Let the requited distance be x km

Total time taken = 1 hour

=>x/6+x/4=1

=> 2x + 3x = 12

=> 5x = 12

=> x = 2.4 km

5. A man can row three-quarters of a kilometer against the stream in 111⁄4 minutes and down the stream in 71⁄2minutes. The speed (in km/hr) of the man in still water is:
A. 4 kmph B. 5 kmph
C. 6 kmph D. 8 kmph

 

Answer : Option B

Explanation :

Distance = 3/4 km

Time taken to travel upstream = 111⁄4 minutes

= 45/4 minutes = 45/(4×60) hours = 3/16 hours

Speed upstream = Distance/Time= (3/4)/ (3/16) = 4 km/hr

Time taken to travel downstream = 71⁄2minutes = 15/2 minutes = 15/2×60 hours = 1/8 hours

Speed downstream = Distance/Time= (3/4)/ (1/8) = 6 km/hr

Rate in still water = (6+4)/2=10/2=5 kmph

6. A boat takes 90 minutes less to travel 36 miles downstream than to travel the same distance upstream. If the speed of the boat in still water is 10 mph, the speed of the stream is:
A. 4 mph B. 2.5 mph
C. 3 mph D. 2 mph

 

   

Answer : Option D

Explanation :

Speed of the boat in still water = 10 mph

Let speed of the stream be x mph

Then, speed downstream = (10+x) mph

speed upstream = (10-x) mph

Time taken to travel 36 miles upstream – Time taken to travel 36 miles downstream= 90/60 hours

=>36/(10−x)−36/(10+x)=3/2=>12/(10−x)−12/(10+x)=1/2=>24(10+x)−24(10−x)=(10+x)(10−x)

=>240+24x−240+24x=(100−x* x)=>48x=100− (x* x)=> x* x +48x−100=0

=>(x+50)(x−2)=0=>x = -50 or 2; Since x cannot be negative, x = 2 mph

7. At his usual rowing rate, Rahul can travel 12 miles downstream in a certain river in 6 hours less than it takes him to travel the same distance upstream. But if he could double his usual rowing rate for his 24-mile round trip, the downstream 12 miles would then take only one hour less than the upstream 12 miles. What is the speed of the current in miles per hour?
A. 2*1/3 mph B. 1*1/3 mph
C. 1*2/3 mph D. 2*2/3 mph

 

Answer : Option D

Explanation :

Let the speed of Rahul in still water be x mph
and the speed of the current be y mph

Then, Speed upstream = (x – y) mph
Speed downstream = (x + y) mph

Distance = 12 miles

Time taken to travel upstream – Time taken to travel downstream = 6 hours

⇒12/(x−y)−12/(x+y)=6

⇒12(x+y)−12(x−y)=6(x*x−y*y)

⇒24y=6(x*x−y*y)

⇒4y= x*x−y*y

⇒x * x =(y* y +4y)⋯(Equation 1)

Now he doubles his speed. i.e., his new speed = 2x

Now, Speed upstream = (2x – y) mph

Speed downstream = (2x + y) mph

In this case, Time taken to travel upstream – Time taken to travel downstream = 1 hour

⇒12/(2x−y)−12/(2x+y)=1

⇒12(2x+y)−12(2x−y)=4*x* x –y* y

⇒24y=4*x* x –y* y

⇒4*x* x = y* y +24y⋯(Equation 2)

(Equation 1 × 4)⇒4x* x =4(y* y +4y)⋯(Equation 3)

(From Equation 2 and 3, we have)

y* y +24y=4(y* y +4y)⇒y* y +24y=4y* y +16y⇒3y* y =8y⇒3y=8

y=8/3 mphi.e., speed of the current = 8/3 mph=2*2/3 mph

MONETARY POLICIES

by

Monetary Policies

Monetary policy is the process by which the monetary authority of a country controls the supply of money, often targeting an inflation rate or interest rate to ensure price stability and general trust in the currency.

Objectives of Monetary Policies are:-

  • Accelerated growth of the economy
  • Balancing saving and investments
  • Exchange rate stabilization
  • Price stability
  • Employment generation

Monetary Policy could be expansionary or contractionary;  Expansionary policy would increase the total money supply in the economy while contractionary policy would decrease the money supply in the economy.

RBI issues the Bi-Monthly monetary policy statement. The tools available with RBI to achieve the targets of monetary policy are:-

  • Bank rates
  • Reserve Ratios
  • Open Market Operations
  • Intervention in forex market
  • Moral suasion

 

Repo Rate- Repo rate is the rate at which the central bank of a country (RBI in case of India) lends money to commercial banks in the event of any shortfall of funds. In the event of inflation, central banks increase repo rate as this acts as a disincentive for banks to borrow from the central bank. This ultimately reduces the money supply in the economy and thus helps in arresting inflation.

Reverse Repo Rate is the rate at which RBI borrows money from the commercial banks.An increase in the reverse repo rate will decrease the money supply and vice-versa, other things remaining constant. An increase in reverse repo rate means that commercial banks will get more incentives to park their funds with the RBI, thereby decreasing the supply of money in the market.

Cash Reserve Ratio (CRR) is a specified minimum fraction of the total deposits of customers, which commercial banks have to hold as reserves either in cash or as deposits with the central bank. CRR is set according to the guidelines of the central bank of a country.The amount specified as the CRR is held in cash and cash equivalents, is stored in bank vaults or parked with the Reserve Bank of India. The aim here is to ensure that banks do not run out of cash to meet the payment demands of their depositors. CRR is a crucial monetary policy tool and is used for controlling money supply in an economy.

CRR specifications give greater control to the central bank over money supply. Commercial banks have to hold only some specified part of the total deposits as reserves. This is called fractional reserve banking.

Statutory liquidity ratio (SLR) is the Indian government term for reserve requirement that the commercial banks in India require to maintain in the form of gold, government approved securities before providing credit to the customers.its the ratio of liquid assets to net demand and time liabilities.Apart from Cash Reserve Ratio (CRR), banks have to maintain a stipulated proportion of their net demand and time liabilities in the form of liquid assets like cash, gold and unencumbered securities. Treasury bills, dated securities issued under market borrowing programme and market stabilisation schemes (MSS), etc also form part of the SLR. Banks have to report to the RBI every alternate Friday their SLR maintenance, and pay penalties for failing to maintain SLR as mandated.

Inflation & Control Mechanism

inflation is a sustained increase in the general price level of goods and services in an economy over a period of time. When the price level rises, each unit of currency buys fewer goods and services.It is the percentage change in the value of the Wholesale Price Index (WPI) on a year-on year basis. It effectively measures the change in the prices of a basket of goods and services in a year. In India, inflation is calculated by taking the WPI as base.

 

 

 

Formula for calculating Inflation=

(WPI in month of current year-WPI in same month of previous year)
————————————————————————————– X 100
WPI in same month of previous year

Inflation occurs due to an imbalance between demand and supply of money, changes in production and distribution cost or increase in taxes on products. When economy experiences inflation, i.e. when the price level of goods and services rises, the value of currency reduces. This means now each unit of currency buys fewer goods and services.

It has its worst impact on consumers. High prices of day-to-day goods make it difficult for consumers to afford even the basic commodities in life. This leaves them with no choice but to ask for higher incomes. Hence the government tries to keep inflation under control.

Contrary to its negative effects, a moderate level of inflation characterizes a good economy. An inflation rate of 2 or 3% is beneficial for an economy as it encourages people to buy more and borrow more, because during times of lower inflation, the level of interest rate also remains low. Hence the government as well as the central bank always strive to achieve a limited level of inflation.

Various measures of Inflation are:-

  • GDP Deflator
  • Cost of Living Index
  • Producer Price Index(PPI)
  • Wholesale Price Index(WPI)
  • Consumer Price Index(CPI)

There are following types on Inflation based on their causes:-

  • Demand pull inflation
  • cost push inflation
  • structural inflation
  • speculation
  • cartelization
  • hoarding

Various control measures to curb rising inflation are:-

  • Fiscal measures like reduction in indirect taxes
  • Dual pricing
  • Monetary measures
  • Supply side measures like importing the shortage goods to meet the demand
  • Administrative measures to curb hoarding, Cratelization.

 

The History of Licchavis

by

 

The Lichchhavis (also Lichchavi, Licchavi) were an important member of the Vajjian confederacy. The early Indian traditions describe the Lichchhavis as Kshatriyas. Scholars reject the theory of foreign origin of the Lichchhavis on the strength of these traditions. But they were degraded to the status of fallen Kshatriyas due to their championship of non-Brahmanical creeds like Jainism and Buddhism.

Rise of the Licchavi Power

In the 6th century B.C. the Licchavi power was firmly established. Though the Lichchhavis belonged to the Vajji confederacy, they had autonomous status. Their capital was Vaisali.

Originally, they seem to have an independent status. The Buddhist records preserve the names of important Licchavi leaders among whom the name of Chetaka deserves special mention. Chetaka’s sister Trisala was the mother of Mahavira, the preacher of Jainism. Chetaka’s daughter Chellana was married to king Bimbisara of Magadha. The Lichchhavis thus appear to be highly connected.

The Magadha-Licchavi Struggle-fall of the Licchavis

The Licchavis turned to be great rivals of Magadhan monarchy. In the reign of Bimbisara of Magadha, they invaded the Magadhan kingdom. In the reign of Ajatasatru, a protracted war began between Magadha and the Lichchhavis. The latter were united with the Vajjis in a confederacy. In the struggle that followed the Lichchhavis and the Vajjis were destroyed.

The causes of the Magadha-Lichchavi war were many. Ajatasatru wanted to take revenge on the Lichchhavis, as their chief Chetaka had refused to extradite Ajatasatru’s step brothers. They had escaped to Vaisali (Licchavi capital) with the royal elephant and family jewels and were granted political asylum. The real cause of the Magadha-Licchavi war was the aggressive imperialism of Magadha against the neighboring republic. The war continued for sixteen years. The Lichchhavis built a mighty alliance with the Vajjis and the other thirty six Ganarajas and also with the kingdom of Kasi-Kosala against Magadha. But the ministers of Ajatasatru sowed seeds of discord among the members of the anti-Magadhan confederacy and destroyed their unity. Ultimately the Vajjian confederacy was destroyed by Ajatasatru. The Vajji territory was annexed to Magadha.

The Licchavi’s republican constitution

There were two Systems of government in the Eastern region. The states of Anga, Magadha, Vatsa etc. were monarchies. Those of Kasf, Kaulala, Videha etc. on the other band were republics. Two of these republics were quite well known, the Republics of the Vajjis or Licchavis and that of the Mallas. Republics were later developments of monarchies and the precursors of democracies. The Licchavis founded their Republic with a view to consolidating their political power. The credit for its foundation goes to Cetaka, who was a wise and valorous king of Videha. He was also the President of the whole Republic. This Republic was the union of eighteen political units, nine of which belonged to the Licchavis and the remaining nine to the Mallas.

The Kings of each unit comprising the Vajji Republic were called Gananayakas. The council of the Gananayakas was called Gana Sabha or Republican Council. It made the constitution and the laws. The individual units were governed in accordance with the constitution of the Gana or the Union. The Vajji Republic was rich and well developed in the fields of Politics, Economics, Society and Religion. The monarchists were highly jealous of this powerful Republic. They were bent upon destroying it. But they were helpless in the face of the powerful Vajjian army.

Videha with its capital at Vaisali was the biggest unit. Vaisali was divided into three zones. The first zone consisted of seven thousand residential houses with golden domes. The middle of the town consisted of fourteen thousand houses with silver domes. The third zone consisted of twenty-one thousand houses with copper domes.

These zones were inhabited by the high, middle and lower classes respectively. Vaisali was not only the capital of the Licchavis, it was the capital of the entire Vajji Republic. It was enclosed within four city walls, each at a distance of two miles from the others. It had several ramparts and entrance-gates. The Republic was a confederation of six clans viz. the Ugras, the Bhojas, the Rajanyas, ihe Iksvakus (the Licchavis), the Jnatasand the Kauravas.

·        Water storage level of India’s 91 major reservoirs drops 2%

  • The water storage available in 91 major reservoirs of the country for the week ending on January 11, 2018 was 80.484 BCM which is 50% of the total storage capacity of these reservoirs. This percentage was at 52 for the week ending January 4, 2018.

 

  • The total storage capacity of these 91 reservoirs is 161.993 BCM, which is about 63% of the total storage capacity of 257.812 BCM which is estimated to have been created in the country. Thirty seven of the 91 reservoirs have hydropower benefit with installed capacity of more than 60 MW.

 

  • The storage during the corresponding period of last year was 58% and average storage of last ten years during the corresponding period was 54% of live storage capacity of these reservoirs. Thus, the storage during the current year is less than that of the previous year and is also less than the average storage of the last ten years during the corresponding period.
