Given :

In a class there are 120 students if 80 are boys.

To find :

The percentage of girls

Solution :

Step 1 of 2 :

Calculate number of girls

Here it is given that in a class there are 120 students if 80 are boys.

Number of total students = 120

Number of boys = 80

∴ Number of girls = 120 - 80 = 40

Step 2 of 2 :

Calculate percentage of girls

Number of total students = 120

Number of girls = 40

Hence the percentage of girls

$\displaystyle \sf = \frac{1}{3} \times 100\%$

$\displaystyle \sf \approx33.33\%$
