In a class, the ratio of girls and boys is 13 : 12. Find the percentage of the girls in the class.

Correct option is B

Given:

Ratio of girls to boys: 13:12

Solution:

Let the total ratio be represented by 13 + 12 = 25 parts.

Girls' share = $$\frac{13\text{ parts }}{25\text{ parts}}$$​= 0.52

Percentage of girls = 0.52 × 100% = 52%

Therefore, the percentage of girls in the class is 52%.
