Question

In a school, the boys and girls are in the ratio $$9 : 5$$. If there are 425 girls, what is the total number of students in the school?

Answer 1

Let the number of boys be $$9x$$ and girls be $$5x$$. 

Given number of girls = $$5x = 425$$. $$x = \frac{425}{5} = 85$$ 

Total number of students = $$9x + 5x = 14x$$. 

Total students = $$14 \times 85 = 1190$$. 

Therefore, the total number of students in the school is 1190.
