Question

16 men can complete a piece of work in 25 days. In how many days can 20 men complete that piece of work?

Answer 1

Step-by-step explanation:

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:

In 20 days 20 men can complete the piece of work.

Step-by-step explanation:

we all know the formula m1*d1=m2*d2 --------->(1)

where m1&m2 are no of men and d1&d2 are no of days

here, m1=16, d1=25, m2=20, d2=x.

so, by eq(1)

16*25=20*x

x=20

Therefore, in 20 days 20 men can complete the piece of work.
