C.	Income and quantity demand	D.	Quantity demanded and quantity supplied

This is an assumption of law of demand:

A.	Price of the commodity should not change	B.	Quantity should not change
C.	Supply should not change	D.	Income of consumer should not change

If quantity demanded is completely unresponsive to changes in price, demand is:

A.	Inelastic	B.	Unit elastic
C.	Elastic	D.	Perfectly inelastic

Other things equal, if a good has more substitutes, its price elasticity of demand is:

A.	Larger	B.	Smaller
C.	Zero	D.	Unity

Price of a product falls by 10% and its demand rises by 30%. The elasticity of demand is:

A.	10%	B.	30%
C.	3	D.	1?3

If elasticity of demand is very low it shows that the commodity is:

A.	A necessity	B.	A luxury

The following are causes of shift in demand EXCEPT the one:

A.	Change in income	B.	Change in price
C.	Change in fashion	D.	Change in prices of substitutes

When demand is perfectly inelastic, an increase in price will result in:

A.	A decrease in total revenue	B.	An increase in total revenue
C.	No change in total revenue	D.	A decrease in quantity demanded

If demand is unitary elastic, a 25% increases in price will result in:
