Question
Suppose there was a $4\%$ decrease in the price of a good, and as a result, the expenditure on the good increased by $2\%$. What can you say about the elasticity of demand?
✓

Answer

Since fall in price has led to rise in expenditure, i.e., both price and expenditure move in the opposite direction, elasticity of demand is greater than unity $(e_D > 1)$.
