Question

if 15 men and do a work in 13 days, how many men will do the same work in 6 days

Answer 1

Dear student,

Using direct proportion method

15 men do work in 13 days

In 13 days 15 men can do the work

In 1 day 13x15 men can do the work

In 6 days $\frac{13\times 15}{6}$ men can do the work

so, in 6 days 32.5 men can do the work
But as men can not be in fraction so we take 33 men.

Regards
