Marks: +1, -0

10 women can complete a work in 7 days and 10 children take 14 days to complete the work. How many days will 5 women and 10 children take to complete the work?

5 days
4 days

Validate

Solution:

5 women's 1 day's work = 5 ×

1/{10×7}

1/{14}

10 children's 1 day's work =

1/{14}

Hence (5 women + 10 children)'s 1 day's work =

1/{14} + 1/{14}

1/7

Therefore, 5 women and 10 children will complete the work in 7 days.
