$\bold{HEYA\:MATE!}$

YOUR ANSWER...

Total no. of students =49
No. of boys =x
No. of girls =2/5x

$\frac{2}{5} x + x = 49$

$\frac{2x}{5} + x$

$\frac{2x + 5x}{5} = 49$

$\frac{7x}{5} = 49$

$7x = 49 \times 5$


$7x = 245$

$x = \frac{245}{7}$

$x = 35$
Therefore, no. of boys in the class is 35.

Total no. of students =49

Let the no. of boys be x

No.of girls be 2/3x

Total no. of students - x+2/5x

x+2/3x=49

7x/5=49

x=35
