Since an equal number of pupils left each school, the difference in the number of pupils at first and in the end between the 2 schools remains the same. Make the difference between the number of pupils in Neave School and Michael School at first and in the end the same.
Difference between the number of pupils in both schools at first
= 25% x 760
=
25100 x 760
= 190
Difference between the number of pupils in both schools in the end
= 3 u - 2 u
= 1 u
1 u = 190
Total number of pupils in both schools in the end
= 3 u + 2 u
= 5 u
= 5 x 190
= 950
Answer(s): 950
