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?
- 400
- 1200
- 1600
- 2800
Correct answer: 1600
Solution
Loss is proportional to deviation squared: 4900 = c*7^2 gives c = 100. For a deviation of 4, loss = 100*4^2 = 1600 rupees. The stored answer 400 is wrong.
