Answer 2

Heya Mate ❣️❣️

The Answer is 33.3%

Explanation ✍️

Given that,

No. Students = 30

No. Girls = 20

No. Boys = Total Students - Girls

30 - 20= 10

So, No. Boys = 10

To Solve,

Percentage of Boys in a Class

$= \geqslant \frac{10}{30} \times 100 \\ = \geqslant 33.3$

Then the percentage of girls will be

$= \geqslant 100 - 33.3 \\ = \geqslant 66.7$

$\fcolorbox{black}{white}{Percentage of Boys is 33.3}$

$\fcolorbox{black}{white}{Percentage of Girls is 66.7}$
