6. An equipment installation job in the completion stage can be completed in 40 days of 8 hour day work, with 40 men working. With the contract expiring in 30 days, the mechanical engineer contractor decided to add 10 men on the job, overtime not being permitted. If the liquidated damage is P 2,000 per day of delay, and the men are paid P 80 per day, will the engineer be able to complete the jobe on time? Would he save money with the addition of workers?
