Class 12 Micro Economics - Chapter Production and Costs NCERT Solutions | What is the marginal product of an input

What is the total product of input?

Why does the SMC curve cut the AVC curve at the minimum point of the AVC curve? 

Let the production function of a firm be Q=5L1/2K1/2Q=5L1/2K1/2 Find out the maximum possible output that the firm can produce with 100 units of LL and 100 units of KK.

What does the average fixed cost curve look like? Why does it look so? 

What do the long-run marginal cost and the average cost curves look like? 

When does a production function satisfy decreasing returns to scale? 

Explain the concept of a production function

Explain the relationship between the marginal products and the total product of an input. 

Why is the short-run marginal cost curve 'U'-shaped? 

At which point does the SMC curve intersect the SAC curve? Give a reason in support of your answer. 

What would be the shape of the demand curve so that the total revenue curve is?

(a) A positively sloped straight line passing through the origin?

(b) A horizontal line?

Explain market equilibrium.

Discuss the central problems of an economy.

What are the characteristics of a perfectly competitive market?

What do you mean by the budget set of a consumer?

From the schedule provided below calculate the total revenue, demand curve and the price elasticity of demand:

When do we say that there is an excess demand for a commodity in the market?

What do you mean by the production possibilities of an economy?

How are the total revenue of a firm, market price, and the quantity sold by the firm related to each other?

What is budget line?

Discuss the central problems of an economy.

What is the reason for the long run equilibrium of a firm in monopolistic competition to be associated with zero profit?

Suppose a consumer wants to consume two goods which are available only in
integer units. The two goods are equally priced at Rs 10 and the consumer’s
income is Rs 40.
(i) Write down all the bundles that are available to the consumer.
(ii) Among the bundles that are available to the consumer, identify those which cost her exactly Rs 40.

The market demand curve for a commodity and the total cost for a monopoly firm producing the commodity are given in the schedules below. 

Use the information given to calculate the following:

(a) The MIR and MC schedules

(b) The quantities for which MIR and MC are equal

(c) The equilibrium quantity of output and the equilibrium price of the commodity

(d) The total revenue, total cost and total profit in the equilibrium

What do you mean by an ‘inferior good’? Give some examples

From the schedule provided below calculate the total revenue, demand curve and the price elasticity of demand:

Compare the effect of shift in the demand curve on the equilibrium when the number of firms in the market is fixed with the situation when entry-exit is permitted.

Consider the demand curve D (p) = 10 – 3p. What is the elasticity at price 53?

Explain why the budget line is downward sloping.

Explain price elasticity of demand.
