Answer #1

Question 1). Answer :- Price elasticity of demand = 0.37

Explanation :- Price elasticity of demand = % Change in quantity demanded / % Change in price.

% Change in quantity demanded = (90 - 70) / [ (90 + 70) / 2 ]

= 20 / (160 / 2)

= 20 / 80

= 0.25

% Change in price = (2 - 1) / [ (2 + 1) / 2 ]

= 1 / (3 / 2)

= 1 / 1.5

= 0.6667 (approx).

Accordingly, Price elasticity of demand = 0.25 / 0.6667 = 0.37 (approx).

Question 2). Answer :- Inelastic demand.

Explanation :- Demand for tomatoes in the given question is inelastic because the Price elasticity of demand for the tomatoes, being, 0.37 is less than 1.
