a. Arrange the following coefficients of price elasticity of demand in ascending order:

-0.7, -0.3, -1.1, -0.8

b. Comment upon the degree of elasticity of demand for Good X, using the total outlay

method, if the price of X falls from 18 per unit to 13 per unit and its quantity demanded

rises from 50 units to 100 units. (1+3)

Using appropriate schedules, briefly describe the determination of market equilibrium.

“In a hypothetical market of mobile phones, the brand AWAAZ was leading the market

share. Its nearest competitor VAARTA suddenly changed its strategy by bringing in a new

model of the mobile phone at a relatively lesser price. In response, AWAAZ too slashed its

price.”

a feature of the market.

Identify which of the following is not true for the Indifference Curves. Give valid reasons

for the choice of your answer:

a. Lower indifference curve represents a lower level of satisfaction.

b. Two regular convex to origin indifference curves can intersect each other.

c. Indifference curve must be convex to the origin at the point of tangency with the budget

line at the consumer’s equilibrium.

d. Indifference curves are drawn under the ordinal approach to consumer equilibrium.

A consumer has total money income of 250 to be spent on two goods X and Y with prices

of 25 and 10 per unit respectively. On the basis of the information given, answer the

following questions:

a. Give the equation of the budget line for the consumer.

b. What is the value of the slope of the budget line?

c. How many units can the consumer buy if he is to spend all his money income on good X?

d. How does the budget line change if there is a fall in the price of good Y?
