# In how many days they can complete work together. If

A, B and C can complete a piece of work I 24,5 and 12 days respectively. Working together, they well complete the some work in:

- 4 days
- 1/24 days
- 7/24 days
- 24/7 days

**All options are wrong.
Correct Answer: 40/13 days**

**Explanation:-
**A can complete a piece of work = 24 days

Therefore, he can a piece of work in a day = 1/24

B can complete the same work = 5 days

Therefore, he can the same work in a day = 1/5

C can complete the same work = 12 days

Therefore, he can the same work = 1/12

A , B and C can together the same work = 1/24 + 1/5 + 1/12

= (5 + 24 + 10)/120

= 39/120

= 13/40

So, A, B and C can together complete the same work = 40/13 days.

Hence, the answer is 40/13 days.
