प्रश्न
When price of a good falls from Rs 20 to Rs 10 per unit, producer reduces supply from 100 units to 50 units. Calculate price elasticity of supply.
उत्तर
Given that
Q0 = 100 units and Q1 = 50 units
P0 = Rs 20 and P1 =Rs 10
ΔP = P1 - P0
ΔP=10-20=-10
ΔQ = Q1 - Q0
ΔQ = 50 - 100=-50 units
We know that
`E_s = (DeltaQ)/(DeltaP)xxP_0/Q_0`
`=(-50)/-10xx20/100`
`=5xx1/5=1`
