A contractor undertake to finish a certain work in 124 days and employed 120 men. After 64 days, he found that he had already done 2/3 of the work. How many men can be discharged so that the work may finish in time ?
Days remaining 124 – 64 = 60 days
Remaining work = 1 – 2/3 = 1/3
Let men required men for working remaining days be ‘m’
So men required = (120 x 64)/2 = (m x 60)/1 => m = 64
Men discharge = 120 – 64 = 56 men.
how may we take this equation
