Qd=100 New Qd=200 Change in Qd=+100(as it rises) Pr=rs 12 New pr=rs 10 Change in price=-2(as it falls) We knw ed=change in qd×pr÷change in pr+Qd So, 100×-2÷12×100 Ans will be -6...minus sign will be ignored so the ans is E.d=6

It is given that, the demand for a commodity increases from 100 units to 200 units when the price of that commodity decreases from 12 to 10 Rs.

We have to find the Elasticity of Demand.

The percentage change in price = (change in price / original price ) X 100

= (2 / 12) X 100

= 16.67%

The percentage change in quantity = (change in quantity / original quantity ) X 100

= (100 / 100 ) X 100

= 100%

The elasticity of demand = % change in quantity / % change in price

= 100 / 16.67  

= 5.99

The elasticity of demand is 5.99.

 

The elasticity of demand comes after dividing the percentage change in quantity with the percentage change in price. Thus, the elasticity of demand is 5.99.
