Question 139

10 women can complete a work in 8 days and 10 children take 12 days to complete the work. How many days will 6 women and 3 children together take to complete the work?

Solution

10 women can complete the work in 8 days. So, number of hours required for 1 woman to complete the work = 80

Number of hours required by one child to complete the work = 120

So, 80W = 120C => 1W = 1.5C

6 women + 3 children = 9 children + 3 children = 12 children

So, 12 children take 10 days to complete the work.
