Question

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

Answer 1

Let her money in the beginning be $Rs.x$
According to the question, spending percentage is $75\%\text{of}x$ and the remaining amount left is $Rs600$
$\Rightarrow x-\left(75\%\text{of}x\right)=600$
$\Rightarrow x-(\frac{75}{100}\times x)=600$
$\Rightarrow x-\frac{3}{4}x=600$
$\Rightarrow x(1-\frac{3}{4})=600$
$\Rightarrow x\left(\frac{4-3}{4}\right)=600$
$\Rightarrow x\left(\frac{1}{4}\right)=600$
$\Rightarrow x=600\times 4=Rs.2400$
Hence, the money in the beginning was $Rs2,400.$
