Please help me out on this.
You are the foreman of a building construction. Theproject engineer assigned you to determine theneeded number of workers for each phase of theconstruction. You know that a group of 5 skilled mencan finish one phase in 6 days while a group of5 unskilled men can finish one phase in 9 days. Theproject has 10 phases. The daily wage of an unskilledworker is PhP 400 while a skilled worker is PhP 700.The completion of the project should not exceed40 days. You will present the plan to the projectengineer. The decision will be based on mathematicalreasoning, accuracy, presentation, practicality, andefficiency

First figure out the cost for each team to complete a project. Which is less expensive? Suppose it were the skilled team - then 1 team could complete six projects in time leaving 4 days of slack time. So, if the skilled team was less expensive, hire two skilled teams; one for 6 projects and one for 4 projects. If you only have the two teams, one skilled and one unskilled, you will have to hire one team for part of the 10 projects and another for the remaining projects.

I did not get it because the skilled team can do only 1 phase in 6 days not 6 phases, and they have higher salary/expenses.

Are the numbers of men in "groups" fixed, or can you hire different numbers of workers? (I think it is necessary to allow for different numbers, and work in terms of "man-hours", in order to find any solution to this exercise.)

Thank you! ;)

How much does a skilled team cost to do one project?

How many complete projects can a skilled team do in 40 days?
How many complete projects can an unskilled team do in 40 days?

Choose the cheapest to do as much as they can in the 40 days and the other team to do the rest.

Yes, you can hire different numbers of workers like 3 unskilled then 7 skilled but I dont know the right number of workers.

You are right, but i'm finding the right number of workers (skilled and unskilled) that when you combine them, they can to 1 phase for 4 days or less than that. And also cheap expenses.
