Question

12 men can do a work in 25 days. how long will 10 men take to complete the work​

Answer 1

✯ Given :

• 12 men can do a work in 25 days.
• find the number of days taken by 10 men to complete the work.

✯ Solution :

• m = men , d = days
• h = hours , w = work

work1 will get cancelled by work2 and we will remove h because hours is not given in the question

$\large \bf\frac{m_1 \: d_1 \: h_1}{w_1} \: = \: \frac{m_2 \: d_2 \: h_2}{w_2} \\ \\ \large \bf \frac{12 \:×\: 25 }{w} \: = \: \frac{10 \:×\:d}{w} \\ \\ \bf \dfrac{300}{10}\: =\:d \\ \\ \bf30\: =\:d \\ \\ \boxed{ \underline{ \sf \therefore \: Days~=~30 }}$

So, days taken to complete the same work by 10 men = 30 days

✯ Answer :

It will take 30 days for the work to be completed by 10 men.
