A contractor agreeing to finish a work in 150 days, employed 75 men each working 8 hours daily. After 90 days, only 2/7 of the work was completed. Increasing the number of men by ________ each working now for 10 hours daily, the work can be completed in time.	Choose the correct choice from the following answers.
A) 322 men	B) 232 men	C) 838 men	D) 539 men	E) 150 men
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.   Answer:150 men
