What will be the % change in quantity demanded, when, the price elasticity of demand is 2 and the % change in price is equal to 5?

10%

Price elasticity of demand (P_ed) = \(\frac{\text {percentage change in quantity demanded for the good }}{\text {percentage change in price for the good }}\)

 2 = \(\frac{\text {% change in quantity demanded for the good }}{\text { 5%}}\)

% change in quantity demanded for the good = 2 * 5%

% change in quantity demanded for the good = 10%
