Question

If Chameli had Rs $600$ left after spending $75$ % of her money, how much did she have in the beginning?

Answer 1

Let the amount of money which Chameli had in the beginning be $x$.
It is given that after spending $75$ % of Rs $x$, she was left with Rs $600$.
Therefore,
$(100 - 75)$ % of $x$ = Rs $600$

Or, $25$ % of $x$ = Rs $600$

$\frac{25}{100} × x$ = Rs $600$

$x$ = Rs $\bigg(600 × \frac{100}{25}\bigg)$ = Rs $2400$

Thus, she had Rs $2400$ in the beginning.
