Answer 1

Step-by-step explanation:

By applying Man - Days, we have :

Men × Time = Work

100 × 1 = 100 unit work

After Increment in work ,

150 × 1 = 150 unit work

Extra man power = 50

But since, new workers are 5/4

time as efficient as existing workers

So,

Actual no. of workers = 50/(5/4)

= 40 workers

% required = 40×100/100=40%
