Question

The sale price of an article including the Sales Tax is Rs 616. The rate of Sales Tax is 10%. If the shopkeeper has made a profit of 12%, then the cost price of the article is

• A. $Rs500$
• B. $Rs515$
• C. $Rs550$
• D. $Rs600$

Answer 1

The correct option is A $Rs500$

Let $C.P.$ be Rs $x$

$\therefore$ $S.P.$ $=x+12\%$ of $x$

$=\frac{112x}{100}=\frac{28x}{25}$
$\therefore \frac{28x}{25}+10\%$of $\frac{28x}{25}=616$
$\Rightarrow x=Rs500$
