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

A15Correct AnswerIncorrect Answer
B12Correct AnswerIncorrect Answer
C16Correct AnswerIncorrect Answer
D14Correct AnswerIncorrect 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
