Q:

A) 10 % | B) 14 ( 2/7 )% |

C) 20 % | D) Can't be determined |

Answer: B) 14 ( 2/7 )%

Explanation:

Explanation:

Let he initially employed x workers which works for D days and he estimated 100 days for the whole work and then he doubled the worker for (100-D) days.

D * x +(100- D) * 2x= 175x

=> D= 25 days

Now , the work done in 25 days = 25x

Total work = 175x

Therefore, workdone before increasing the no of workers = $\frac{25x}{175x}\times 100$ % = $14\frac{2}{7}\%$
