Assuming that all the men do the same amount of work in one day and one day work of each
man = 1 units, we have,
Amount of work done by (x − 2) men in (4x + 1) days
= Amount of work done by (x − 2)(4x + 1) men in one day
= (x − 2)(4x + 1) units of work
Similarly,
Amount of work done by (4x + 1) men in (2x − 3) days
= (4x + 1)(2x − 3) units of work
According to the given information,
