The coefficient of elasticity of supply of a commodity is 3. A seller supplies 20 units of this commodity at a price of 8rs per unit. How much quantity of this commodity will the seller supply if the price rises by 2rs per unit.

Answer»

Solution :
PES `=(DeltaQ)/(DELTAP)xx(P)/(Q)
3=(DeltaQ)/(2)xx(8)/(20)`
`DeltaQ=(120)/(8)=15`
As PRICE increases,quantity suppliedalso increases as per law of SUPPLY
NEW Quantity =Initial Quantity+DeltaQ =20+15=35`
