    Question

    A group of 'x' men can finish a job in 46 days. If 8

    additional men had joined the group, they could have completed the same job 16 days earlier. Assuming all men work at the same efficiency level, determine the value of 'x'.
    A 15 Correct Answer Incorrect Answer
    B 12 Correct Answer Incorrect Answer
    C 16 Correct Answer Incorrect Answer
    D 14 Correct Answer Incorrect Answer

    Solution

    Let efficiency of each man = ‘M’ units/day ATQ, (x × M × 46) = {(x + 8) × M × (46 – 16)} Or, 46x = 30x + 240 Or, 16x = 240 Or, x = (240/16) = 15
