Ratio of girls is 5x

Total no of girls = 320

5x=320

X= 64

Ratio of boys = 9x

9×64= 576

Total number of students in school

is equals to sum of boys and girls

320+576= 896

In school, boys : girls = 9 : 5

Total value = 9 + 5 = 14

Boys fraction = 9/14

Girls fraction = 5/14

Let, total strength of school = x

Given that,

number of girls = 320

==> x * 5/14 = 320

==> x = 320 * 14/5

==> x = 896

Hence, the strength of school = 896
