Given: Contractor X employs 200 men to build a dam. They finish 5/6 of the work in 10 months. Then rain sets in and not only does the work remain suspended for 4 months but also half of the work already done is washed away. After the rain, when the work is resumed, only 140 men turn up.
Asked: The total time in which the contractor is able to complete the work assuming that there are no further disruptions in the schedule is
Men = 200
Time = 10 months
Work completed = 5/6
Men-months needed to complete the whole work = 200*10*6/5 = 2400 men-months
Men-months completed = 2000 men-months
Time wasted because of suspension = 4 months
Since half of the work already done is washed away.
Men-months wasted = 1000 men-months
Remaining men-months = 2400 - 2000 + 1000 = 1400 men-months
