x = 40

Number of boys = 40 multiplied by 7

= 280

Number of boys = 280

Answer 2

Step-by-step explanation:

Let the number of boys and girls in the school be 7x and 5x.

Then, A/q

$\therefore 7x+5x=480$

$\implies 12x=480$

$\implies x=\frac{480}{12}$

$\implies x=40$

$\because \mathtt{Number \;of\; boys\; in\; the \;school = 7\times40= 280 }$

$\mathtt{and\; Number \;of \;girls\; in \;the \;school = 5\times40=200}$
