5 girls from 5A to 5B, 5 boys from 5B to 5A. Eventually, class 5A has 44 students.


Before
[ Boys ] [ Girls ] = 44
After
[ Boys + 5] [Girls - 5] = 44
let u be the number of girls after 5 girls were transferred from 5A to 5B, then
[3u][u] = 44
u = 11

number of girls at first is 11 + 5 = 16

Hope the explanation is clear.[/quote]
