A piece of work can be completed by 10 men in certain number of days.If there were 2 men less it would have taken 3 more days to complete the work. In how many days can 24 men complete the same work?

Read Solution (Total 2)

5 DAYS

let 10 man completed that work on x days.
so one man's one day work=1/(10*x)
now 2 man less and it would have taken 3 days more
so, one man's one day's work=1/8(x+3)
now,
1/(10*x)=1/8(x+3)
x=12

So,
10 MEN TAKES 12 DAYS
1MEN 1 DAY = 1/120
24MEN 1 DAY = 24/120=1/5
