If the demand function of a new product is $P(x)= 4000 -150x,$ then the marginal revenue when 10 units are sold is : |
500 2500 2000 1000 |
1000 |
The correct answer is Option (4) → 1000 Revenue is given as, $R(x)=P(x)×x$ $=(4000-150x)×x$ $=4000x-150x^2$ Marginal Revenue, $MR=\frac{d}{dx}(4000x-150x^2)$ $=4000-300x$ $MR(10)=4000-300×10$ $=1000$ |
