Answered

A and B together can do a piece of work in 6 days. If A can alone do the work in 18 days, then the number of days required for B to finish the work is

- 9
- 15
- 12
- 10

Best answer

**Answer: (1) 9 days**

**Explanation:-**

A and B together can do a piece of work = 6 days

Therefore, A and B can do a piece of work in a day = 1/6

A can alone do the work = 18 days

A can alone do work in a day = 1/18

Then, B can alone do work in a day = 1/6 – 1/18

= (3 – 1)/18

= 2/18

= 1/9

Therefore, B can alone finish the work = 9 days

Hence, the answer is (1) 9 days.
