Question

In a class, the ratio of boys to girls is $4:3$. If there are $18$ girls, then find the boys in the class.

Answer 1

Let $x$ be the no. of boys in the class.

Now, according to the question-

$\frac{x}{18}=\frac{4}{3}$

$\Rightarrow x=\frac{4\times 18}{3}=4\times 6=24$

Hence there are $24$ boys in the class.
