Q. A and B together can complete a work in 18 days. A alone takes 30 days. After working together for 6 days, A leaves. In how many more days will B finish the remaining work?
✅ Correct Answer: (C)
30 days
Explanation: B's rate = 1/18 - 1/30 = 1/45. Completed in 6 days = 1/3. Remaining = 2/3. Time = (2/3)/(1/45) = 30 days.
