✰ Let the number of girls be = X

$\: \:$

$\therefore$ 35% of boys = x

$\: \:$

$\large \implies \rm \: \dfrac{35}{100} \times 1500 = x$

$\: \:$

$\large \implies \rm \: \dfrac{35}{ \cancel{100}} \times 15 \cancel{00 }= x$

$\: \:$

$\large \implies \rm \: 35 \times 15 = x$

$\: \:$

$\large \therefore \boxed{ \rm \: x = 525}$
