Question

18 men can complete a piece of work in 63 days. 9 women take 189 days to complete the same piece of work. How many days will 4 men, 9 women and 12 children together take to complete the piece of work if 7 children alone can complete the piece of work in 486 days?

Answer 1

Answer:

Hopefully I remember school....

18 men = 63 days, 4 men = 283.5 days

9 women = 189 days, 9 women = 189 days

7 children = 486 days, 12 children = 283.5 days

4 men + 9 women + 12 children = 283.5 days + 189 days + 283.5 days = 756 days.

756 days is equivalent to 2.069815195071869 years.
