Question

if 12men and 16 boys can do a piece of work in 5 days and 13 men can do it in 4 days,compare the daily work done by a man with that of done by a boy ?​

Answer 1

Answer:

Given:

13 men can do a piece of work in 4 days.

Therefore, one man can do it in 52 days.

So 12 men can do the same piece of work in 52/12 days.

But we even have 16 boys working.

Their work is done alone in 5-52/12 days =0.7 days

The same piece of work done by one boy is 0.7×16=11.2 days.
