The work these men do is creating highly complex pieces of a machine. 35 are needed and each piece takes a man 20 days to complete.

If only 25 men are employed there will only be 25 pieces done after 20 days so it will take another 20 days to produce the rest.

Total, 40 days.

It depends greatly on the type of work.
