Answer 2

Answer:

Please Mark Me as brainiest

Step-by-step explanation:

We are given that the boys and girls in a school are in the ratio 8:5.

Let the ratio be x

So, number of boys = 8x

Number of girls = 5x

We are given that the total number of girls is 160

So,  

x= 32

So, number of boys = 8x=8*32 = 256

So, total strength = 256+160 = 416

So, the strength of the school is 416
