The total revenue in Rupees received fro...

The total revenue in Rupees received from the sale of x units of a product is given by `R(x)=3x^2+36 x+5`. The marginal revenue, when `x = 15`is (A) 116 (B) 96 (C) 90 (D) 126

Text Solution

Verified by Experts

We have `R(x)=3x^2+36x+5`
`implies` Marginal revenue(MR)=`(dR(x))/dx=6x+36`
Thus at `x=15`,Marginal revenue=`6(15)+36=126`
Option `D` is correct
