Question

A man spends $\frac{3}{8}$ of his money and still has Rs. 720 left with him. How much money did he had at first?

• A. Rs. 1920
• B. Rs. 1450
• C. Rs. 1152
• D. Rs.1476

Answer 1

The correct option is C Rs. 1152

Let the initial amount be x.
So, he spends $\frac{3}{8}$ of x.
Amount remaining with him = $x-\left(\frac{3}{8}\right)$
=$\frac{5x}{8}$
According to question, this amount should be equal to Rs. 720.
$\Rightarrow$ $\frac{5x}{8}=Rs.720$
$\Rightarrow$ $x=Rs.1152$
