Question

If 10 men can complete a piece of work in
30days, how many men are required to
complete the same in 25 days?​

Answer 1

Answer:

Always go step by step for easily understanding.

20 men —30 days

1 man - 30*20 days=600 days

25 men=600/25 days

=24 days

So 25 men require 24 days to complete that job

Answer 2

Answer:

by inverse proportion

$\frac{10}{30} = \frac{?}{25}$

$\frac{ {x}^{1} }{ {x}^{2} } = \frac{ {y}^{2} }{ {y}^{1} }$

$\frac{10}{ {x}^{2} } = \frac{25}{30}$

$\frac{10 \times 30}{25} = {x}^{2}$

$12 = {x}^{2}$

the answer is 12 men are needed to complete the work in 25 days
