A and B work together. A alone can complete the work in 18 days and B alone in 36 days. What percentage of the total daily work is contributed by A? MCQ with Answer and Explanation
Explanation:
Total work = LCM(18, 24, 36) = 72 units. Efficiency of A = 4, B = 3, C = 2. Combined efficiency = 4 + 3 + 2 = 9 units/day. Time taken together = 72 / 9 = 8 days.
