# A can Finish the Remaining Work in:

A can do a piece of work in 20 days which B can do in 12 days. B worked at it for 9 days. A can finish the remaining work in :

- 3 days
- 5 days
- 7 days
- 11 days

**Answer: (2) 5 days**

**Explanation:-**

A can do a piece of work = 20 days

Therefore, A can do work in a day = 1/20

B can do the same work = 12 days

Therefore, B can do the work in a day = 1/12

B can do the work in 9 days = 9/12

= 3/4

Remaining work = 1 – 3/4

= (4 – 3) /4

= 1/4

Then, A can finish the remaining work = 20 x 1/4

= 5 days

Hence, the answer is (2) 5 days.
