Question

The ratio of the number of girls to that of boys in a school is $9:11$.If the number of boys in the school is $2035$, find:

the number of girls in the school

Answer 1

Given that ratio of the number of girls to that of boys in a school $=$ $9:11$

number of boys in the school $=$ $2035$

Let number of girls in the school $=$$x$

Then,

$\frac{Numberofgirls}{Numberofboys}=\frac{9}{11}$

$$\begin{gathered} \frac{x}{2035}=\frac{9}{11} \\ x=\frac{9\times 2035}{11} \\ x=1665 \end{gathered}$$

Hence, the number of girls in the school is $1665$
