Answer 2

Number of girls in the school is 180.

The ratio of boys and girls in a school is 5 : 3. If there are 300 boys.

We have to find the number of girls in the school.

Let the proportionality constant is k.

So the number of boys = 5k

and the number of girls = 3k

Here, number of boys = 5k = 300

⇒k = 60

∴ number of girls = 3k = 3 × 60 = 180

Therefore the number of girls in the school is 180.
