Q. In manufacturing industries, loss is usually taken to be proportional to the square of the deviation from a target. If the loss is Rs. 4900 for a deviation of 7 units, what would be the loss in Rupees for a deviation of 4 units from the target?
| (A) 400 | (B) 1200 | (C) 1600 | (D) 2800 |
Ans: 1600
Sol:
Loss =kd2 For duration of 7 units
4900=k(7)2 ⇒k=100
Loss =kd2 For duration of 4 units
=k(4)2 ⇒16k=1600
