There are total of 300 students in the school. If 40% of them are girls, find the total number of girls in the school.

Given, Percentage of boys= 40%

Total number of students in the school = 300

$\therefore$Total number of boys in the school = 40% of 300

$\Rightarrow$ $\frac{40}{100}\times 300$

$\Rightarrow$  120, students are girls.
