Question

if 36 men can do a piece of work in 25 days find the numbers of men required to complete the same job in 15 day ?​

Answer 1

Here less men, more days.

∴ Let in x days, 15 men can finish the work

Therefore

men 36. 15

day. 25. x

By inverse variation

36:15=x:25

$\frac{36}{15} = \frac{25}{x}$

$\frac{36 \times 25}{15}$

∴ The work will be finished in 60 days
