Answer 2

GIVEN:

• % of girls in school=60%
• Girls=18

TO FIND:

• Total number of students.

SOLUTION:

Let total number of students be x

So according to the question:-

$\sf : \implies \: \: 60 \% \: of \: x=18$

$\sf : \implies \: \: \frac{60}{100} \times x = 18$

$\sf : \implies \: \: x = \frac{18 \times 100}{60}$

$\sf : \implies \: \: x = \cancel\frac{1800}{60}$

$\large\underline{ \boxed{ \sf \blue{X=30}}}$

So total no. of students=x=30
