Answer by Glaviolette(140)   (Show Source):
You can put this solution on YOUR website! Looking at it as an inverse variation. 15 = k/36. k = 540
Then, 10 = 540/x
x = 54
54 - 36 means 18 additional workers are needed

You can put this solution on YOUR website! .
The entire construction work is 36*15 = 540 working days.
To complete it in 10 days,  = 54 workers are needed.
So, additional 54 - 36 = 18 workers should be employed.
Answer by htmentor(1343)  (Show Source):
You can put this solution on YOUR website! The job will take 36 people x 15 days = 540 people-days to complete
This means, for example, that it would take one person 540 days,
18 people 30 days, etc. to complete
Thus, to finish in 10 days, the total number of people required is 54
So he needs to hire 18 additional workers
