One day's work = 2 / (7 * 90)
One hour's work = 2 / (7 * 90 * 8)
One man's work = 2 / (7 * 90 * 8 * 75)
The remaining work (5/7) has to be completed within 60 days, because the total number of days allotted for the project is 150 days.So we get the
equation(2 * 10 * x * 60) / (7 * 90 * 8 * 75) = 5/7
where x is the number of men working after the 90th day.
We get x = 225
Since we have 75 men already, it is enough to add only 150 men..
