-
- 10 men can do the piece of work in 15 days so the total men power required is
15 x 10 =150
so 25 women can finish the same piece of work in 150 /25= 6 days
answer is 3) 6 Days

- 6 days
10 men's, 5 day work= 5/15= 1/3, Remaining work= 2/3
If 1 woman takes 'x' days to complete the work, then
10 women's, 1 day work=10/x
Given, 10 men & 10 women completes the remaining 2/3 work in 5 days
So, 5[(1/15)+(10/x)]= 2/3 , x= 150
As 1 woman can complete the whole work in 150 days,
So 25 women will finish the same work in 150/25 =6 days - 10 years agoHelpfull: Yes(1) No(0)
