- B. 12 days
- C. 10 days
- D. 16 days
Show answer and explanation
Answer: B. 12 days
In 2 days (A then B) they do 1/6. After 5 such pairs (10 days) the work done is 5/6. A works one more day, then B finishes the remaining 1/24 in 1 day(s). Total = 12 days.

- A. 7/18
- B. 2/3
- C. 5/9
- D. 1/2
Show answer and explanation
Answer: C. 5/9
Work done = 8/18 = 4/9. Remaining = 1 - 4/9 = 5/9.
- A and B can do a job in 12 days, B and C in 16 days, and C and A in 24 days. In how many days can all three together do it?
- A. 11 2/3 days
- B. 8 2/3 days
- C. 7 2/3 days
- D. 10 2/3 days
Show answer and explanation
Answer: D. 10 2/3 days
Adding: 2(A + B + C) = 1/12 + 1/16 + 1/24 = 3/16. So A + B + C = 3/32 a day, and the time = 10 2/3 days.
- A can do a piece of work in 10 days and B can do it in 15 days. In how many days can they finish it together?
- A. 9 days
- B. 5 days
- C. 7 days
