A can complete a work in 14 days and B can complete the same work in 19 days. If they work together, in how many days will the work be completed? MCQ with Answer and Explanation

Explanation:
Combined rate = 1/16 + 1/29. Required time = 10.31 days.

Explanation:
Combined rate = 1/18 + 1/24. Time = 10.29 days.

Explanation:
Let efficiency of B = 10, then efficiency of A = 13. Total work = Efficiency of A * Time taken by A = 13 * 23 = 299 units. Combined efficiency of A and B = 13 + 10 = 23. Time taken together = 299 / 23 = 13 days.
