Answer 1

✒Question:-

☛If 36 men can do a piece of work in 25 days. In how many days will 15 men do it.

✒Solution:-

A person working for a day is normally known as a man day .

So this work takes 36*25 = 900 man days to be finished. If the number of men get reduced, then the number of days must increase as the man days remain constant. Number of days required to finish the work,

= 900/15 = 60 days

✔Answer

✌60 days✌

The work requires 36*25 man-days to complete. So if 15 men are to do the same work they will take 36*25 man-days/15 men = 60 days.
