business studies, she decided to study the feasibility of marketing good quality rice at a

reasonable price. Her father suggested her to use internet to gather customer’s views and

opinions. She found that there was huge demand for packaged organic rice. She knew that there

were no predetermined specifications in case of rice because of which it would be difficult to

achieve uniformity in the output. To differentiate the product from its competitors, she gave it

the name of ‘Malabar Organic Rice’ and classified it into three different varieties- Popular,

Classic and supreme based on the quality.

Explain the three functions of marketing with reference to above case.

4. The marginal utility from the consumption of commodity-X is given in the following table:

Units of X 1 2 3 4 5

MUx 10 9 7 3 -5

5. A consumer gets 50 utils of utility from the consumption of 1st unit commodity-X. On the

assumption that for every additional unit of X, he loses 10 utils, how much units of X will

he consumes if, it was available to him at price of Rs. 5 per unit, and his marginal utility of

money = 10?

6. On the consumption of 10 units of a commodity, a consumer finds that MUx has exceeded

the marginal utility of money. Should he reduce the consumption of X so that he strikes

equilibrium. Give reason in support of your answer.

falls to 20 units. Calculate the price elasticity.

17. Suppose the price elasticity of demand for a good is -0.2. If there is a 5 per cent increase in

the price of the good, by what percentage will the demand for the good go down?

18. 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 per cent increase in the price of the good?

19. Suppose there was a 4 per cent decrease in the price of a good, and as a result, the

expenditure on the good increases by 2 per cent. What can you say about the elasticity of

demand?
