Question

In a school with a total of $480$ students, the ratio of boys to girls is $8:7$. How many girls attend the school?

• A. $212$
• B. $224$
• C. $256$
• D. $322$
• E. $420$

Answer 1

The correct option is B $224$

Let the number of boys be $8x$ and girls be $7x$
Total number of students $=8x+7x=480$
$\Rightarrow 15x=480$
$\Rightarrow x=32$
So, number of girls that attended the school $=7x=7\times 32=224$
