A man, a woman and a boy together complete a piece of work in 3 days. If a man alone can do it in 6 days and a boy alone in 18 days, how long will a woman take to complete the work?

Answer»

9 days



(Man + Boy + WOMAN)’s 1 DAY’s work = 1/3 

Man’s 1day’s work = 1/6 

Boy’s 1 day’s work = 1/18 

Then, Woman’ 1 day’s work = 1/3 – ( 1/6 + 1/18) = 1/3 – 4/18 =2/18 = 1/9 

Therefore, the Woman ALONE can FINISH the work in 9 days.
