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'.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
