At the market price of 10rs , a firm supplies 4 units of output. The market price increases to 30rs. The price elasticity of the firm's supply is 1.25. What quantity will the firm supply at the new price ?

Answer»

SOLUTION :
PRICE elasticity of supply (PES) `=(DeltaQ)/(DeltaP)xx(P)/(Q)`
`1.25=(DeltaQ)/(20)xx(10)/(4)`, i.e., `DeltaQ=10`
As price increases, then quantity supplied ALSO increase. It means,
New Qunatity =Original Quantity (Q) + Change in Quantity `(DeltaQ]=4+10=14` units.
New Quantity `=14` units
