13 men can complete a work in 29 days. If 17 men work at the same rate, in how many days will the work be completed? MCQ with Answer and Explanation

Explanation:
A share = (1/18) / (1/18+1/30) ×100 = 62.5%.

Explanation:
Total work = LCM(20, 30) = 60 units. Efficiency of A = 3, B = 2. In 4 days, work completed = 4 * (3 + 2) = 20 units. Remaining work = 60 - 20 = 40 units. Time taken by B to finish remaining work = 40 / 2 = 20 days. Total days = 4 + 20 = 24 days.

Explanation:
Combined rate = 1/24 + 1/34. Time = 1 ÷ combined rate = 14.07 days.
