Answer 2

Given,

Total students in school = 750, and,

Of them, boys are 60%.

To find,

The number of girls.

Solution,

We can solve this problem simply by following the below process.

This problem involves the use of percentages. So, the percent means per 100, or, a fraction of 100. For example, x percent (x%) means x as a fraction of 100 that is, x/100.

It is given that the total number of students is 750. Further, in the school 60% of the total students are boys.

So, the number of boys will be,

$\frac{60}{100} *750\\=0.6*750$

= 450.

⇒ The number of boys = 450.

Now, the number of girls in school can be determined as,

Girls = 750 - 450.

= 300.

Therefore, the number of girls in school is 300.
