प्रश्न
The price of a commodity increase from ₹ 10 to ₹ 14. Calculate percentage fall in quantity demanded of the commodity if the coefficient of price elasticity of demand is (−) 1.25.
उत्तर
Given:
P1 = 10
P2 = 14
Price Elasticity of Demand = 1.25
Percentage fall in quantity demanded = ?
Percentage rise in price = `("P"_2-"P"_1)/("P"_1) xx 100 = (14-10)/(10) xx 100 = 40%`
The elasticity of Demand = `" Percentage fall in quantity demanded"/"Percentage in price"`
(-) 1.25 = `"Percentage fall in Quantity Demanded"/(40%)`
Percentage Change in Quantity Demanded = 1.25 x 40% = 50%
