Question

a work done by 12 men or 15 women in 20 days. what is the time taken by 4 men and 5 women. to complete this

Answer 1

12 men can finish this work in 20 days.

so 4 men can finish it in 60 days.

so 4 men's one day's work = 1/60.

15 women can complete the same work in 20 days.

so 5 women can complete it in 60 days.

so 5 women's one day's work = 1/60

4 men's one day work + 5 women's one day work.
1/60 + 1/60 = 1/30

their one day work is 1/30. So they will finish the work in 30 days.
