Question : Which of the subsequent assertions is untrue:
a) Higher elasticity number suggests a greater impact of a change in price on the quantity desired.
b) Demand elasticities can only fluctuate between -1 and +1.
c) Rectangular hyperbola demand curves will exist for all commodities with unitary elastic demand.
Option 1: A only
Option 2: B only
Option 3: A and C only
Option 4: B and C only
Correct Answer: B only
Solution :
The range of the price elasticity is (minus) infinity to zero. Demand is more elastic the closer it is to infinity, and more inelastic the closer it is to zero.
Hence option b is the correct option.
