A certain job has been estimated to take 10 men 5days.
So the total number of mendays = 10*5 = 50
On day 4 half the job has been completed.
That means 25 mendays has been completed.
The remaining mendays = 50-25 = 25
In order to complete the work on the fifth day 25 men have to do work.
Therefore the number of additional men required = 25-10 = 15
