The total cost of producing x generators is given by
$TC= x^3-60x^2+1500x+2000.$
The Marginal Cost (MC), when x = 10 units is :
Answer & explanation
Correct answer: option 3
Given total cost
$TC=x^3-60x^2+1500x+2000$
Marginal cost
$MC=\frac{d(TC)}{dx}$
$MC=3x^2-120x+1500$
At $x=10$
$MC=3(10)^2-120(10)+1500$
$=300-1200+1500$
$=600$
The marginal cost at $x=10$ units is ₹600.
