Question

If $\frac{4}{7}$ of a class of 28 students are girls, then how many girls are there in the class ?

• A. 15
• B. 5
• C. 8
• D. 16

Answer 1

The correct option is D 16

$\frac{4}{7}{}^{th}$ of the total number of students are girls.
$\frac{4}{7}{}^{th}$ of the total strength.

So, $\frac{1}{7}{}^{th}$ of the total strength
= 28 ÷ 7 = 4

So, $\frac{4}{7}$ of total students will be 4 × 4 = 16.
So, there are 16 girls in the class.
