Question

$in \: a \: class \: of \: 48 \: student \: \: the \: number \: of \: boys \: is \: \frac{3}{5 \: } ofthe \: numberof \: girls \: the \: number \: of \: girls \: in \: the \: class$

Answer 1

Let the number of girls be x

So number of boys = 3x/5

Now girls + boys = 48
=> x + 3x/5 = 48
=>
$\frac{5x}{5} + \frac{3x}{5} = 48 \\ = \frac{8x}{5} = 48 \\ x = 48 \times \frac{5}{8} \\ x = 30$
Here we have to find only the number of girls. So number of girls is 30



Hope it helps dear friend ☺️✌️✌️
