In a class of CSS, there are 70% girls if there are 25 boys, how many total students are in the class?

Let x be total students in a class.

If there are 70% girls in class, it means 30% are boys.

we can write it as:

⇒ 30% of students in class = 25 boys

The equation will be:

⇒ \frac{30}{100}\times x\ =\ 25

Keep the x on left side, and bring other value to right side

it will become,

x\ =\ \frac{25\times100}{30}

x\ =\ \frac{5\times100}{6}

x\ =\ \frac{500}{6}

x=\ 83.3

A. 83.3

B. 90

C. 80

D. 70

### Answer & Solution

**Answer:**The correct answer is

**83.3**students.

**Solution:**

Let x be total students in a class.

If there are 70% girls in class, it means 30% are boys.

we can write it as:

⇒ 30% of students in class = 25 boys

The equation will be:

⇒ \frac{30}{100}\times x\ =\ 25

Keep the x on left side, and bring other value to right side

it will become,

x\ =\ \frac{25\times100}{30}

x\ =\ \frac{5\times100}{6}

x\ =\ \frac{500}{6}

x=\ 83.3

**Hence, There are total 83.3 students in the class.**
