Given: 45 men can complete a piece of work in 24 days.
To find The number of men should be added to complete the same work in 20 days
Solution: The problem given is a Time-Work problem in mathematics where it is assumed a man to be an agent of any work and time tells usually in hours or days.
From above, we have
The number of men required to complete a piece of work in 24 days = 45
The number of men required to complete a piece of work in 1 day= 45×24
∴ The number of men required to complete a piece of work in 20 days
= (45×24)/20
= 1080/20
= 54
∴The number of men should be added to complete the same work in 20 days,
= 54-45
=9
Hence the number of men who should be added to complete the same work in 20 days is 9.
