A completes a work in 12 days whereas B completes the same work in 24 days. If both A and B work together, the work will be completed in ____?
- 6
- 8
- 10
- 12
Explanation
A completes the work in 12 days.
So, A's 1-day work:
1/12
B completes the work in 24 days.
So, B's 1-day work:
1/24
Together, their 1-day work:
1/12 + 1/24
LCM of 12 and 24 = 24:
2/24 + 1/24
= 3/24
= 1/8
Therefore, they will complete the whole work in:
8 days
