    Question

    40 men take 15 days to finish some work. If the work is

    to be finished in 8 days, then how many additional men should be hired?
    A 35 Correct Answer Incorrect Answer
    B 75 Correct Answer Incorrect Answer
    C 65 Correct Answer Incorrect Answer
    D 25 Correct Answer Incorrect Answer

    Solution

    Let the total work be 'w' units and efficiency of each man be 'e' units/day Let number of men required to finish the work in 8 days be 'm'. ATQ; W/(40 x 15 x e) =  W/(8 x e x m)   m = 75 So, 75 - 40 = 35 more men should be hired.
