INTRODUCTION • Explain the problem of ‘How to produce’ with the help of an example. • What does a production possibility curve show? When will it shift to the right? • Define Opportunity cost? • Why does an economic problem arise? Explain the problem of ‘what to produce’. • What is a market economy? • Why is a production possibilities curve concave? Explain. • Give the meaning of an Economy? • What is ‘ Marginal Rate of Transformation’? Explain with the help of a numerical

example. • Explain the central problem ‘for whom to produce’. • What is positive and normative economics? CONSUMER BEHAVIOUR AND DEMAND • Distinguish between expansion of demand and increase in demand. • Explain the Law of demand with the help of demand schedule and curve. • Explain the meaning of normal goods and inferior goods. • Explain the expenditure method of measuring price elasticity of demand of a commodity. • Explain with the help of diagrams the effect of the following changes on the demand of a

commodity. • A fall in the price of substitute good. • A fall in the income of its buyer.

• Distinguish between (i) Individual demand and market demand, (ii) ‘Change in demand’ and ‘change in quantity demanded’.

• A consumer consumes only two goods. Explain his equilibrium with the help of utility approach.

• Explain the causes of a rightward shift in demand curve of a commodity of an individual consumer.

• How is the price elasticity of demand of a commodity affected by the number of its substitutes? Explain.

• Define marginal rate of substitution. Explain why is an indifference curve convex? • A consumer buys 10 units of a good at a price of Rs. 9 per unit. At price of Rs. 10 per unit.

He buys 9 units. What is price elasticity of demand? Use expenditure approach. Comment on the likely shape of demand curve on the basis of this measure of elasticity.

• State the characteristics of indifference curve? • Explain the Law of diminishing marginal utility with the help of a utility schedule. • A consumer spends Rs. 1,000 on a good priced at Rs. 10 per unit. When its price falls by

20 percent, the consumer spends Rs. 800 on the good. Calculate the price elasticity of demand by the Percentage method.

1. Show that f : R+ [-5, ) given by f(x) = 9x2 + 6x – 5 is invertible with f –1(y) =

3

16y.

2. If R1 and R2 are equivalent relations in a set A, show that R1R2 is also an equivalent relation.

3. Show that the relation R in the set A = { x ε Z : 0 ≤ x ≤ 12 } given by R = { (a, b) : | a – b | is a multiple of

4} is an equivalence equivalent. Find the set of all elements related to 1

4. Check whether the following relations R in R are reflexive, symmetric or transitive:

(i) R = { ( a, b ) : a ≤ b }

(ii) R = { ( a, b ) : a ≤ b2 }

(iii) R = { ( a, b ) : a ≤ b3 }

5. Show that the relation R defined in the set A of all triangles as R = { ( T1, T2 ) : T1 is similar to T2 } is an

equivalence relation. Consider the three triangles T1with sides 3, 4, 5, T2 with sides 5, 12, 13 and T3 with

sides 6, 8, 10. Which triangles among T1, T2and T3 are related?

6. State whether the following functions are injective, surjective or none:

(i) f: N →N given by f(x)= x2

(ii) f: Z →Z given by f(x)= x2

(iii) f: R →R given by f(x)= x2

(iv) f: N →N given by f(x)= x3

(v) f: Z →Z given by f(x)=x3

(vi) f: R →R given by f(x)= [x] where [x] denotes the greatest integer function.
