Question

Q.11. The demand curve of a commodity is expressed as Dx=
40-5P. If slope of the demand curve is given to be (-2),
calculate price elasticity of demand for the commodity
when demand is 20 units.​

Answer 1

If slope of the demand curve is given to be (-2) , calculate price elasticity of demand for the commodity when demand is 20 units. Solution : Dx=40-5P: putting the value of demand (i.e 20 units) we get 20 = 40 -5P , i.e p=₹ 4.
