Due to decrease in manpower, the production in a factory decreases by 25%. By what per cent should the working hours be increased to restore the original production?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. %.
Let the initial production be 100 units.
New production = 75% of 100 = 75 units
Working hours should be increased = 100 - 75 = 25 units
Required percentage = (25/75) × 100
⇒ %
