Answer 1

Answer:

Hours to increase = 33%

Step-by-step explanation:

Hours to increase = 33%

◆ Explanation -

Let X be the original production.

After fall in manpower, production decreased to -

Decreased production = X - 25%X

Decreased production' = X - 0.25X

Decreased production = 0.75 X

To restore the production to original, hours increased will be -

Hours to increase = (X - 0.75X) / 0.75X

Hours to increase = 0.25X / 0.75X

Hours to increase = 0.33

Hours to increase = 33%

Therefore, 33% hours should be increased in order to restore original production.
