Total no of girls = 320
5x=320
X= 64

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
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
