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.
P1 = Rs.10
P2= Rs.10
M = Rs. 40
Budget set = P1X1+P2x2≤ M
10X1+10x2 ≤ 40
The bundles that are available to the consumer should cost less than or equal to Rs40.

The bundles in the shaded region (∆AOB) are all available
to the consumer, including the bundles lying on the line
AB.

What is the supply curve of a firm in the long run?
The market price of a good changes from Rs 5 to Rs 20. As a result, the quantity supplied by a firm increases by 15 units. The price elasticity of the firm’s supply curve is 0.5. Find the initial and final output levels of the firm.
A firm earns a revenue of Rs 50 when the market price of a good is Rs 10. The market price increases to Rs 15 and the firm now earns a revenue of Rs 150. What is the price elasticity of the firm’s supply curve?
Distinguish between a centrally planned economy and a market economy.
How does the imposition of a unit tax affect the supply curve of a firm?
A consumer wants to consume two goods. The prices of the two goods are Rs 4
and Rs 5 respectively. The consumer’s income is Rs 20.
(i) Write down the equation of the budget line.
(ii) How much of good 1 can the consumer consume if she spends her entire
income on that good?
(iii) How much of good 2 can she consume if she spends her entire income on
that good?
(iv) What is the slope of the budget line?
Questions 5, 6 and 7 are related to question 4.
What is the relation between market price and average revenue of a price-taking firm?
What is budget line?
Suppose there are 20 consumers for a good and they have identical demand functions:
d(p)=10–3pd(p)=10–3p for any price less than or equal to 103103 and d1(p)=0d1(p)=0 at any price greater than 103.
Suppose your friend is indifferent to the bundles (5, 6) and (6, 6). Are the preferences of your friend monotonic?
If a consumer has monotonic preferences, can she be indifferent between the
bundles (10, 8) and (8, 6)?
What do the long-run marginal cost and the average cost curves look like?
Consider the demand for a good. At price Rs 4, the demand for the good is 25 units. Suppose the price of the good increases to Rs 5, and as a result, the demand for the good falls to 20 units. Calculate the price elasticity.
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 is budget line?

Suppose the price elasticity of demand for a good is – 0.2. If there is a 5 % increase in the price of the good, by what percentage will the demand for the good go down?
Suppose the price elasticity of demand for a good is – 0.2. How will the expenditure on the good be affected if there is a 10 % increase in the price of the good?
