comment upon the degree of elasticity of demand for commodity x if the price of the commodity falls from rs.28 per unit to rs.23 per unit and itz quantity demanded rises from 50 units to 100 units.

Elasticity=change in demand *price / change in price *demand 
hence,according to the question,elasticity  =5.6 
since elasticity is greater than 1 ,it is relatively elastic as change in demand is greater than change in price .
This condition holds true for luxurious goods.
