The market price of good changes from 5rs to 20rs. As a result, the quantity supplied by a firm increases by 15 units. The price elasticity of the firm's supply curve is 0.5. Find the initial and final output levels of the firm.

Answer»

Solution :
Price elasticity of supply (PES) `=(DELTAQ)/(DeltaP)xx(P)/(Q)`
`0.5=(15)/(15)xx(5)/(Q)`, i.e., `Q=10`
As price increases, then quantity supplied also increase. It means,
Final Output =Initial Output (Q) +Change in Quantity (DeltaQ]
`=10+15=25` units
Initial Output (Q)=10 units, Final Output `(Q_(1))=25` units.
