Answer 2

Marginal revenue = 12

Explanation:

Given;

When price is Rs.20 then quantity demand is 15 units

When price is 18 then quantity demand is 16 units

Output(Q) = 9 units to 10 units

Marginal revenue = ?

We know that,

$Marginal\ revenue = \frac{\Delta T\times R}{\Delta Q}$

$Marginal\ revenue = \frac{16\times 18 - 20\times 15}{9 - 10}$

$Marginal\ revenue = \frac{288 - 300}{ - 1 }$

Or,

Marginal revenue = 12
