${\huge{\pink{\underline{\underline{\purple{\mathbb{\bold{\mathcal{AnSwEr..}}}}}}}}}$

${\large{\blue{\bold{\underline{Given:-}}}}}$

▪︎ $\huge\frac{3}{5}$ of the total students are girls.

▪︎ Number of boys = 200.

▪︎ Let the total number of students be x.

▪︎ So number of girls = $\huge\frac{3}{5}x$

${\large{\blue{\bold{\underline{Now\:ATQ:-}}}}}$

$\implies \frac{3}{5}x + 200 = x \\ \\ \implies \frac{3x}{5} + 200 = x \\ \\ \implies \frac{3x + 1000}{5} = x \\ \\ \implies3x + 1000 = 5x \\ \\ \implies3x - 5x = - 1000 \\ \\ \implies - 2x = - 1000 \\ \\ \implies \: x = \cancel\frac{ - 1000}{ - 2} \\ \\ \implies \: x = 500$

☆ Therefore the total number of students are 500.
