Question

# Ramu can complete of the work in 5 days and Ravi can complete of the same work in 6 days How long would both of them take to complete that work, if they work together ?

- 18 days
- 12 days
- 16 days
- 20 days

## The correct answer is: 12 days

### To find the number of days take to complete that work, if Ramu and Ravi work together.

Ramu can complete of the work in 5 days.

1 day work of Ramu = = 0.05.

Ravi can complete of the same work in 6 days.

1 day work of Ravi = = 0.0333.

1 day work if they work together = 0.05+0.0333 = 0.0833.

Total number of days that take to complete the work if they work together = = 12.

Therefore, to complete the work, It takes 12 days if they work together.

Therefore, the money should be divided in the ratio of 5:4:3

i.e, A's share=400

B's share=320

C's share=240
