Question:

When price of a good falls from Rs 12 per unit to rs 9 per unit, the producer supplies 75% less output. Calculate price elasticity of supply.

Options:

1

2

3

4

Correct Answer:

3

Explanation:

The correct answer is Option 3: 3

Price elasticity of supply ($e_s$)= Percentage change in quantity supplied /Percentage change in price

                                                      = [(△Q/Q)*100]/[(P/△P)*100]

                                                      = [△Q/Q] * [P/△P]
 
Percentage change in quantity supplied  = -75%
Percentage change in price = (-3/12)*100 = -25%
$e_s$ = -75%/-25% =3
