Question
30 men can complete a work in 12 days. After 6 days, 24
more men joined them. How many days will they now take to complete the remaining work?Solution
Let, the efficiency of a man = y ATQ- (30 x y x 6) + (54 x y x D) = 30 x y x 12 (54 x y x D) = 30 x y x6 D = (30 x 6)/54 = 10/3 D = 3(1/3) days
