# In How Many More Days is the Work Completed? If

20 men can do a piece of work in 18 days. They worked together for 3 days, then 5 men joined them. In how many more days is the work completed?

- 12
- 14
- 15
- 13

**Answer: (1) 12 days**

**Explanation:-**

20 men can do piece of work = 18 days

20 men can do work in a day = 1/18

Therefore, 20 men can do work in 3 days = 3/18 = 1/6

Remaining work = 1 – 1/6 = 5/6

5 men joined them

Then, the number of men = 20 + 5 = 25

25 men can do work in a day = 6 x 25/18 x 20 x5 = 1/12

25 men can do work complete = 12 days

Hence, the answer is (1) 12 days.
