Test: Theory Of Demand- 3 - Question 17

Increase in Price from Rs. 4 to Rs. 6 then decrease in demand from 15 units to 10 units. What is the price elasticity. (Point elasticity)

Detailed Solution for Test: Theory Of Demand- 3 - Question 17

∆P = P1 - P = 6 - 4 = 2

∆Q = Q1 - Q = 10 - 15 = -5

Price Elasticity= P/Q × ∆Q/∆P =

(-) 4/15×(-)5/2

=0.66

Test: Theory Of Demand- 3 - Question 18

In case of a straight line demand curve meeting the two axes, the price elasticity of demand at the mid-point of the line would be:

Test: Theory Of Demand- 3 - Question 19

Price of Tiffin Box is Rs. 100 per unit and the quantity demanded in market is 1,25,000 units. Company increased the price to Rs. 125. Due to this increase in price, quantity demanded decreases to 1, 00,000 units. What will be the price elasticity of demand?

Detailed Solution for Test: Theory Of Demand- 3 - Question 19

Correct Answer :- C

Explanation : Q1 = 100                 P1 = 125000

Q2 = 125                 P2 = 100000

(Q2-Q1)/Q = P(P2-P1)

=> (25000/125000) * (100/25)

= 4/5

= 0.8

Test: Theory Of Demand- 3 - Question 20

In case of an inferior good, the income elasticity of demand is: 

Test: Theory Of Demand- 3 - Question 21

Cross elasticity of complementary goods is:

Test: Theory Of Demand- 3 - Question 22

Which of the following elasticity of demand measures a movement along the demand curve rather than a shift in the curve?

Test: Theory Of Demand- 3 - Question 23

Generally, when income of consumer increases, he goes in for superior goods, leading to a fall in demand for inferior goods. It means, income elasticity of demand is ________.

Detailed Solution for Test: Theory Of Demand- 3 - Question 23

In case of inferior goods, there will be negative income elasticity (Ey<0).

Test: Theory Of Demand- 3 - Question 24

For a commodity with a unitary elastic demand curve if the price of the commodity raises, then the consumer’s total expenditure on this commodity would: 

Test: Theory Of Demand- 3 - Question 25

Suppose the price of movies seen at a theatre rises form Rs. 120 per person to Rs.200 per person. The theatre manager observed that the rise in prices has lead to a fall in attendance at a given movie from 300 persons to 200 persons. What is the price elasticity of demand for the movie? (arc elasticity)

Detailed Solution for Test: Theory Of Demand- 3 - Question 25

Arc elasticity may be expressed as: [(Q1 - Q)/(Q1 + Q)] x [(P1 + P)/(P1 - P)]

Therefore,

[(300 - 200)/(300 + 200)] x [(200 + 120)/(200 - 120)]

= (100/500) x (320/80)

So, Arc elasticity = 4/5 = 0.8

(differences were large hence arc elasticity is used.)
