Answer : Option A
Explanation :
ATQ, target = work should be finished in 38 days
Now, after assigning more workers, the work is finished in 37 days.
Note: man * days = total work
As per the given information,
Total work = (30 Men * 25 days) + (35 men * 12 days) = 30*25 + 35*12
Or, total work = 750 + 420 = 1170
Note: 1 worker = 1 unit work per day
So, if work is done by 30 workers, i.e., 30 units of work per day
The number of days required = total work/ work per day
= 1170/30= 39 days
Target with 30 workers = 38, but it will take 39 days
So, work will be late by 1 day.
