Q. A and B can complete a work in 18 days, B and C in 24 days, and C and A in 36 days. In how many days can A, B and C together complete the work?
✅ Correct Answer: (C)
16 days
Explanation: Adding pairwise rates: 2(A+B+C) = 1/18 + 1/24 + 1/36 = 1/8. Thus, A+B+C = 1/16, so they take 16 days. Therefore, option3 is correct.
