Question 26

In a class composed of x girls y boys what part of the class is composed of girls ?

Solution

No. of girls in class=x.
No. of boys in class=y.
Part of the class is composed of girls=$$\frac{No. of girls}{No. of students}$$.
$$=\frac{No. of girls}{No. of girls+No. of boys}$$
$$=\frac{x}{x+y}$$
Hence, Option C is correct.
