Let AT be all together.

1/4 AT+ 1/3 AT + 1/6 AT + 300=AT
3/12 AT + 4/12 AT + 2/12 AT+300=AT
9/12 AT +300=AT
solve for AT

9th = 1/4
10th = 1/3
11th = 1/6
1/4 + 1/3 + 1/6= 1/4+2/6+1/6
=1/4 + 3/6
=1/4 + 1/2 =3/4
300= 25% or 1/4
3/4= 3* 300= 900

let total no of students=T
so in 9th class= T/4
in 10th class=T/3
in 11th class=T/6
so in 12th class=T-[(T/4)+(T/3)+(T/6)]
= T/4
and is given that, students in 12th class= 300
so total students in school= 300*4=1200
