Question
Ram and Shyam can complete a
piece of work together in 15 days. If Shyam is 50% more efficient than Ram, find how long Shyam alone will take to finish the work.Solution
ATQ, Let the efficiency of Ram alone = 6 units/day. Then, efficiency of Shyam alone = 6 + 6 à 0.5 = 9 units/day. Total work = (6 + 9) à 15 = 225 units. Thus, time taken by Shyam alone to complete the work = 225 á 9 = 25 days.
