Asher School had 408 students and Gabriel School had 25% more students. When an equal number of students left each school, the ratio of the students in Gabriel School to that in Asher School became 3 : 2. How many students were there in both schools in the end?

	Asher School	Gabriel School	Difference
Before	408		102
Change	- ?	- ?
After	3 u	2 u	1 u

Since an equal number of students left each school, the difference in the number of students at first and in the end between the 2 schools remains the same.  Make the difference between the number of students in Asher School and Gabriel School at first and in the end the same. 

Difference between the number of students in both schools at first
= 25% x 408
= ²⁵₁₀₀ x 408
= 102

Difference between the number of students in both schools in the end
= 3 u - 2 u
= 1 u

1 u = 102

Total number of students in both schools in the end
= 3 u + 2 u
= 5 u
= 5 x 102
= 510

Answer(s): 510
