Question

In a class , the ratio of boys to girls is 16 : 25. What part of the whole class are girls ?

• A. $\frac{25}{41}$
• B. $25$
• C. $\frac{25}{28}$
• D. $\frac{16}{25}$

Answer 1

The correct option is A

$\frac{25}{41}$

Given that ratio is 16 : 25

$\therefore$ Total number of students in the class = 16 + 25 = 41

Hence the fraction of girls = $\frac{\text{Number of Girls}}{\text{Total number of students in the class}}$

= $\frac{25}{41}$
