It turns out that boys are girls: 5/6

1 After the transfer of boys, boys are girls: 87.5%.

There are more boys 1, but more girls: 87.5%-5/6 = 1/24.

So girls have: 1 ÷ 1/24 = 24.

Boys used to have: 24 * 5/6 = 20.

It turns out that a * * * has: 24+20 = 44.

Solution:

Female students: 1 ÷ (87.5%-5/6) = 24 (people).

Boys used to have: 24 x 5/6 = 20 (person)

6 1 grade: 24+20 = 44 (person)
