Question

A husband, wife and child can do a piece of work in 6 days. wife alone can do the work in 16 days, child alone can do the work in 24 days then husband alone can do the work in how many days?

Answer 1

Wife 1 day work = 1/16
Child 1 day work = 1/24
One day work of all three together = 1/6
1 day work of man alone,
= 1/6 - 1/16 - 1/24
= (8-3-2) / 48
= 3/48
= 1/16
Man alone can do it in 16 days
