Solution
Given, number of boys in the class = 36
Percentage of girls in the class = 55%
$$\Rightarrow$$ Percentage of boys in the class = 45%
Let total students in the class = x
$$\Rightarrow$$ 45% of x = 36
$$\Rightarrow$$ $$\frac{45}{100}$$x = 36
$$\Rightarrow$$ x = 80
$$\therefore\ $$Total number of students in the class = 80
