Given : 72 men are engaged for a task with a timeline given beforehand.
It is found that in 38% of the given time 36 % of the task is completed
To Find : . How many additional men are to be engaged so that the timeline can be met
Solution:
Let say Total Work = 100W and to Be completed in 100D Days
Let say a Man do work A in 1 Day
38% of the given time = 38D says
Work Done = 72A * 38 D
36 % of the task is completed => Work Done = 36W
72A * 38 D = 36W
=> AD = W/76
Work Left = 100W - 36W = 64W
Days Left = 100D - 38D = 62D
Let say Men now = M
So Work done = MA62D
= 62M (AD)
= 62M ( W/76)
62M ( W/76) = 64W
=> M = 64 x 76 / 62
=> M = 78.45
As time line need to met so we need to round up men
=> M = 79
Additional Men Required = 79 - 72 = 7
