Question

A man loses $12\frac{1}{2}$ % of his money and after spending 70% of the remainder, he was left with Rs. 210. The money that he had at the beginning is

• A. Rs. 810
• B. Rs. 800
• C. Rs. 790
• D. Rs. 780

Answer 1

Answer: (B)

Rs. 800

Let Rs. $x$ be the amount at the beginning.

Loss $=12.5\%$

Remainder $=\frac{87.5x}{100}$

$210=\frac{30}{100}\times \frac{87.5x}{100}$

$\therefore x=800$
