# How Much Work will me Left?If

A can do piece of work in 25 days and B can do the same work in 30 days. They work together for 5 days, how much of work left?

- 15/30
- 19/30
- 11/30
- 12/30

**Answer: (2) 19/30
Explanation:-**

A can do a piece of work = 25 days

A can do work in a day = 1/25

B can do a piece of work = 30 days

B can do work in a day = 1/30

They do work together in 5 days = 5(1/25 + 1/30)

= 5(6 + 5)/150

= 11/30

Remaining work = 1 – 11/30 = 19/30

Hence, the answer is (2) 19/30.
