Rajiv Gandhi began a peace initiative in Punjab, Assam and Mizoram and also in the neighbouring country of Sri Lanka.

Correct option: (A) a–4, b–3, c–2, d–1

Correct option: (B) Deuteromycetes

In deuteromycetes sexual reproduction is not known and so are termed fungi imperfectii.

Correct option: (C) Autotrophy

Autotrophy is a characteristic of plants.

Correct option: (C) Chitin

Cell wall of most fungi is made up of chitin.

Correct option: (B) Chitin

Chitin is a natural structural polysaccharide, which is found in both insects and fungi. In fungi it forms the cell wall while in insects it foms the protective covering.

Sublimation: 

This method can be applied to only those compounds that change their state directly from solid to vapor on heating. Hence this method can be used for separating the sublimable compounds from the non-sublimable impurities.This process is known as sublimation.

A crystalline form of carbon is sugar.

(i) Synthetic detergents can be used even in acidic solutions.

(ii) They can be used even in hard water.

(iii) They have stronger cleansing action than soaps

Correct option: (b) license

Correct option: (a) Abraham Shipman

Correct option: (a) Union Jack

According to Bernoulli's theorem, when velocity of liquid flow increases, pressure decreases and vice-versa. When two boats move parallel to each other, close to one another, the stream of water between the boats is set into vigorous motion. As a result, the pressure exerted by the water in between the boats becomes less than the pressure of water outside the boats. Due to this pressure difference, the boats are pulled towards each other.

Various techniques for measuring time intervals are given below:

(i) Electrical oscillators: These use a.c supply of frequency 50 Hz, The rotations of a synchronous motor run on a.c. is used to obtain at scale.

(ii) Electronic oscillators: A vacuum tube or a semi- conductor device is used to produce electromagnetic oscillations of a very high frequency. The time period of such oscillations can be used to measure small time intervals.

(iii) Quartz crystal clocks: Quartz crystal shows piezo electric effect that is, if such a crystal is subjected to a fluectuating pressure across its one pair parallel forces, an oscillatory e.m.f is developed across another pair which is perpendicular to earlier pair of face and vice-versa.The oscillations so produced can be used to measure time intervals Such clocks are quite in use these days.

(iv) Atomic clocks: Such clocks make use of periodic vibrations taking place within the atoms like that of caesium.

(v) Decay of elementary particles : Many unstable elementary particles decay in very short time interval from 10^-10 second to 10^-24 second. By studying this decay, very small time intervals can be measured.

(vi) Redioactive dating: Very long intervals,Such as age of fossils (carbon dating), rocks and earth (uranium dating ) etc. are estimated by a technique known as radioactive dating.

B) Rectangles

Correct option is  B) Rectangles

Sum of the frequencies.

B) Number of classes

Correct option is  A) Pie chart

Vertical and horizontal bar graphs are used to present the equal widths corresponding to the given frequencies.

Class Interval

Normal goods are the goods the demand for which increases as income of the buyer rises and there is a positive relationship between income and demand.

Goods whose demand decreases when the income of consumer increases, are called ‘Inferior Goods.’

Correct option is  B) C

Assumptions:

1. Absence of excess capacity in consumer goods industries. 

2. Constant capital – output ratio 

3. Increase in demand is assumed to be permanent 

4. Supply of funds and other inputs is quite elastic 

5. Capital goods are perfectly divisible in any required size.

There are three elements of demand for a commodity. 

These are:

1. Desire for a commodity.
2. Money to fulfil that desire.
3. Readiness to spend money.

Correct option is  D) None

Correct option is  C) 20

D) Assumed mean

Correct option is  D) none

Commodities have many uses. If their price rises, they are used only for more important purposes. As a result, their demand will go down. On the contrary, when the price is reduced, they will be put to different uses and their demand will rise. For example, with the increases in the electricity charges, power will be used primarily for domestic lighting, but if the charges are reduced, people will use power for cooking, fans, heaters, etc.

Correct option is  A) a

Monetary policy is the policy adopted for supply and availability of credit in an economy. Central Bank adopts this policy to control the money supply or to attain objectives of economic policy.

Correct option is   B) \(\frac{a+b+c}{3}\)

When the price of the commodity falls, then the consumer replaces the object which has now become relatively dear, with other objects. If the price of tea falls, it will be used by some people in place of other beverages to some extent. The reason is not far to seek, when the price of a commodity falls, the consumer’s marginal utility for that commodity becomes comparatively high. Hence to increase his total satisfaction, he finds it worthwhile to purchase more of the cheaper commodity as against the dearer one. In contrast, when the price of a commodity rises, other commodities will be used in its place, at least to some extent. Therefore, a fall in the price of a commodity increases demand and a rise in its price reduces demand.

The effect of income is positive when increase in income causes increase in demand. It occurs in case of normal goods. Whereas the effect of income is negative when increase in income causes decrease in demand. It occurs in case of inferior goods.

Correct option is  D) 5

Correct option is  C) 10.5

When two goods are used as the alternative of one another, they are called Substitute Goods.

Assumptions of the. law of demand refer to all other determinants of demand, except for price of the commodity. These other determinants are assumed to remain stable.

It is said that when there is a demand for change in response to the change in the price of the other, the goods are related. For example, increase in the price of coffee is expected to cause increase in demand for tea. So tea and coffee are related goods. Whereas goods are unrelated or not affected by each other, when demand for one is independent of any change in price of the other. Demand for shoes, for example, is not affected by change in price of sugar. Shoes and sugar are thus unrelated goods.

Correct option is  D) 30

Complementary means a product that is associated with another product and can be used together only, or such goods which are jointly consumed.

2. Bread and butter

Correct option is  C) Mean
