Question

A women alone can complete apiece of work in 10 days,where as 10 children alone take 15 days to complete the same piece of work.how many days will 6 women and 10 children together take to complete the piece of work ?

Answer 1

1 woman can do a peice of work in 10 days

1 woman can do a peice of work in 10 days therefore 6 woman can do same work in 10/6 days

i.e.5/3 days

1 day work of children= 3/5

10 children do work in 15 days

1 day work of children=1/15

Total work = 5/3+1/15

=26/15

time required = 15/26

hope it helps you :)
