Answer:

Question 14.
Find out Median value of the following distribution: [4]

Answer:

Median value = Size of \(\left(\frac{N}{2}\right)^{\mathrm{th}}\) Items
= Size of \(\left(\frac{161}{2}\right)^{\mathrm{th}}\) Items
Size of 80.5th item (which lies in 20 – 30 wage group)
By Interpolation:
Median = \(\mathrm{L}_1+\frac{\frac{N}{2}-C \cdot F}{\mathrm{f}} \times \mathrm{i}\)
Where
L₁ = 20, C.F = 60 f = 46 i = 10

= 24.45

Question 15.
“An index number is a statistical device for measuring changes in the magnitude of a group of related variables. It represents the general trend of diverging ratios, from which it is calculated.”
Elaborate how index number measures the changes in the magnitude of variables. [4]
OR
What is the importance of Statistics in economic planning?
Answer:
Index number is a measure of the average change in a group of related variables over two different situations. It helps us to find out percentage change in the values of different variables over time with references to some base year which happens to be the year of comparison. The comparison may be between like categories such as persons, schools, hospitals etc. The method of index number measure alters from one variable to another related variable.
OR
These days almost all the countries of the world adopt the method of planning for economic development. Statistics is the most important tool in economic planning. Statistics helps economic planning by collecting data of national resources both human and natural. For drawing a plan of their use, we need the help of Statistics.

Question 29.
What are the characteristics of a perfectly competitive market? [3]
OR
Explain the implications of the feature “homogeneous product” in a perfectly competitive market.
Answer:
Perfect Competition: This type of market structure refers to the market that consists of a large number of buyers and also a large number of sellers. No individual seller is able to influence the price of an existing product in the market. All sellers in a perfect competition produce homogenous outputs, i.e., the outputs of all the sellers are similar to each other and the products are uniformly priced.

Characteristics of a Perfectly Competitive Market:
(i) Large number of buyers and sellers: There exist a large number of buyers and sellers in a perfectly competitive market. The number of sellers is so large that no individual firm owns the control over the market price of a commodity. Due to the large number of sellers in the market, there exists a perfect and free competition.

(ii) Homogenous products: All the firms in a perfectly competitive market produce homogeneous products. This implies that the output of each firm is perfect substitute to others’ output in terms of quantity, quality, colour, size, features, etc. This indicates that the buyers are indifferent to the output of different firms. Due to the homogenous nature of products, existence of uniform price is guaranteed.

(iii) Free exit and entry of firms: In the long-run, there is free entry and exit of firms. However, in the short run some fixed factors obstruct the free entry and exit of firms. This ensures that all the firms in the long-run earn normal profit or zero economic profit that measures the opportunity cost of the firms either to continue production or to shut down.

(iv) Perfect knowledge among buyers and sellers: Both buyers and sellers are fully aware of the market conditions; such as price of a product at different places. The sellers are also aware of the prices at which the buyers are willing to buy the product. The implication of this feature is that if any individual firm is charging higher (or lower) price for a homogeneous product, the buyers will shift their purchase to other firms (or shift their purchase from the firm to other firms selling at lower price).

(v) No transport costs: This feature means that all the firms have equal access to the market. The goods are produced and sold locally. Therefore, there is no cost of transporting the product from one part of the market to other.

(vi) Perfect mobility of factors of production:
There exists geographically and occupationally perfect mobility of factors of production. This implies that the factors of production can move from one place to other and can move from one job to another. (Any three)
OR
Homogeneous products imply that the products are identical in quality, shape, size and colour. So, no producer is in a position to charge a different price for the product it produces. A uniform price prevails in the market. In a perfectly competitive market, commodity is homogeneous (identical). Thus, the buyers find no reason to prefer the product of one seller to the product of another. Hence, the firms are price takers. In a perfectly competitive environment, homogeneous product does not allow a firm any control over its price. Accordingly, firm’s demand curve (under perfect competition) becomes a horizontal straight line.

Question 30.
A consumer spends ₹1,000 on a good priced at ₹8 per unit. When price rises by 25 percent, the consumer continues
to spend ₹1,000 on the good. Calculate price elasticity of demand by percentage method. [4]
Answer:
Given, P = ₹8, Total expenditure = ₹1,000. If P increases by 25%, i.e., 25% of ₹8 would be ₹2
Thus, New Price P₁ = ₹8 + ₹2 = ₹10. Here again
Total Expenditure = ₹1,000
Total Expenditure = ₹1,000

Question 31.
Complete the following table: [4]

OR
Giving reasons, state whether the following statements are true or false: [4]
(i) Average product will increase only when marginal product increases.
(ii) With increase in level of output, average fixed cost goes on falling till it reaches zero.
(iii) Under diminishing returns to a factor, total product continues to increase till marginal product reaches zero.
(iv) When there are diminishing returns to a factor, total product always increases.
Answer:

OR
(i) False. Average product will increase only when marginal product is greater than average product whether MP is rising or falling.

(ii) False. AFC = TFC/Output. TFC is constant and positive. So with an increase in output AFC will fall but can never be zero.

(iii) True. Under diminishing returns MP falls. TP increases till MP is positive.

(iv) False. This is because in a situation of diminishing returns to a factor marginal product tends to fall. Falling MP implies that total product should be increasing, though at a diminishing rate. TP will increase till MP remains positive.

Question 32.
Using a diagram explain what happens to the PPC of Kashmir if the widespread floods have led to the destruction
of human lives? [4]
Answer:
Production possibility curve (or PPC) is drawn on the assumption that the given resources are fully as well as efficiently utilised. If the widespread floods in Kashmir have led to the destruction of human lives, it implies the loss of manpower. This will shift the PPC leftward from ab to ajbj, as shown in Figure.

Question 33.
(a) Central problems arise because resources and scarce and have alternate uses and want are unlimited. Explain.
(b) Describe the problem of “What to Produce?”.
OR
(a) Explain the meaning and implications of maximum price ceiling and minimum price ceiling [3]
(b) Define Price Ceiling. What is the common purpose for the price ceiling imposed by the government? Explain any one likely consequence of this nature of intervention by the government in the price determination process.
m [3]
Answer:
(a) Central problem of all economies is scarcity. Scarcity forces individuals, firms, governments and societies to make choices. By this, three basic questions arise : (i) What to produce, (ii) How to produce, (iii) For whom to produce. 2 + 1 = 3

(b) This problem involves selection of goods and services to be produced and the quantity to be produced of each selected commodity. Every economy has limited resources and thus, cannot produce all the goods. More of one good or service usually means less of others. For example, production of more sugar is possible only by reducing the production of other goods. Production of more war goods is possil U only by reducing the production of civil goods. So, on the basis of the importance of various goods, an economy has to decide which goods should be produced and in what quantities. This is a problem of allocation of resources among different goods. The problem of ‘What to produce’ has two aspects :
(i) What possible commodities to produce : An economy has to decide which consumer goods (rice, wheat, clothes, etc.) and which of the capital goods (machinery, equipment, etc.) are to be produced. In the same way, economy has to make a choice between civil goods (bread, butter, etc.) and war goods (guns, tanks, etc.).
(ii) How much to produce : After deciding the goods to be produced, economy has to decide the quantity of each commodity that is selected. It means, it involves a decision regarding the quantity to be produced, of consumer and capital goods, civil and war goods and so on.
OR
(a) When the government imposes upper limit on the price of a good it is called maximum price ceiling. It is fixed below the equilibrium price. Implication (maximum price ceiling) : It will lead to excess demand. This in turn may lead to black marketing of goods.

When the government imposes lower limit on the price of a good, it is called minimum price ceiling.
Implication (minimum price ceiling) : It leads to excess supply. This in turn may lead to illegal selling below the ceiling price as the producers are not able to sell what they desire to sell.

(b) Price Ceiling: Price ceiling means the maximum limit that the government imposes on the price of a commodity. Price ceiling are used by the government to prevent prices from being too high.

The main reason for imposing price ceilings is to protect the interests of the consumers in situations in which they are not able to afford needed commodities. For example – During the recent rise in the prices of pulses.

Consequence:
Shortages of the commodity and rationing : In case of price ceiling the quantity actually supplied in the market will shrink; as a result, a large chunk of consumer’s demand will go unsatisfied. To deal with such a situation the government may resort to rationing of the commodity.

Question 34.
Read the passage given below and answer the questions that are followed:
Production, exchange and consumption of goods and services are among the basic economic activities of life. In the course of these basic economic activities, every society has to face scarcity of resources and it is the scarcity of resources that gives rise to the problem of choice. The scarce resources of an economy have competing usages. In other words, every society has to decide on how to use its scarce resources. Every society must decide on how mu(h of each of the many possible goods and services it will produce. Whether to produce more of food, clothing, housing or to have more of luxury goods.
(a) Why does the problem of ‘what to produce’ arise? Explain. [2]
(b) Human wants are unlimited in number. They are never ending and they can never be fully satisfied. Justify. [4]
Answer:
(a) This problem involves selection of goods and services to be produced and the quantity to be produced for each selected commodity. Every economy has limited resources and thus, cannot produce all the goods. More of one good or service usually means less of others.

For example, production of more sugar is possible only by reducing the production of other goods. Production of more war goods is possible only by reducing the production of civil goods. So, on the basis of the importance of various goods, an economy has to decide which goods should be produced and in what quantities. This is a problem of allocation of resources among different goods.

(b) This problem is concerned with the distribution of income in an economy. It is concerned wdth whether to produce goods for high-income groups or low-income groups. The capacity of people to pay for goods depends upon their level of income. Thus, this problem is concerned with distribution of income among factors of production who contribute in the production process. It has two aspects:
(i) Personal distribution: It means national income of an econom distributed among different grouj people in the society.
(ii) Factorial distribution: It relates to in share of different factors of production as wages for labour, interest for capital for land, etc.
