A and B together can complete a piece of work in 35 days while A alone can complete the same work in 60 days. In how many days, B alone will be able to complete the same work?
Correct Answer: 84 days
Explanation:
In this question, A and B did the work for 35 days to complete it. A can complete the work in 60 days.
So, A did/A can + B did/B can = 1
⇒ 35/60 + 35/x = 1
⇒ x = 84 days
