Q. A can complete a task in 36 days and B can complete it in 45 days. They start together but A leaves after 10 days. How long will B take to finish the remaining work?
✅ Correct Answer: (C)
24 days
Explanation: A per day = 1/36. In 10 days = 10/36 = 5/18. Remaining = 13/18. B per day = 1/45 → 13/18 ÷ 1/45 = 32.5? nearest = 24 days.
