A contractor has a job which should be completed in 120 days. At present, he has 80 men on the job and it is estimated that they will finish the work in 150 days. Of the 80 men, 50 are each paid Php 150.00 a day, 25 at Php 210.00, and 5 at Php 280.00. For each day beyond the original 120 days, the contractor has to pay Php 1,500.00 liquidated damages.

Complete solution needed A building constructor has a contract which will expire in 50 days. He has 80 men on the job and can finish the job in 80 days. The wage per day of 40 men is P800.00 each and that of the other 40 men is P500.00 each for 8 hours work per day. The fine or liquidated damages for delay in the work is P15,000.00 per day. How many more men should the contractor add in order to enable him to complete the work on time? Assuming that the additional men to be added will be paid P500.00 per day, will the contractor save money by employing enough men for him to complete the work on time or by not adding more men and paying the fine? How much is the savings, if any? No overtime work is permitted.
