At a price of ₹ 20 per unit, the qty. dd of a commodity is 300 units. If its price falls by 10% quantity rises by 60 units. Find `P.e_(D)`.

Text Solution

Verified by Experts

Price after change is ₹ 20- ₹ 2 ( 10% of 20)= ₹ 18
Quantity rises by 60 so new quantity is 300+60=360 units.
`P=20, P_(1)=18, Delta=-2`
`Q=300, Q_(1)=360 , DeltaQ= 60`
` p.e_(D)= P/Qxx(DeltaQ)/( DeltaP) or P.e_(D)= 20/300 xx 60/ (-2)`
` P.e_(D) = -2`
`|P.e_(D)|=2 `
