Question

The final price after applying a 10% discount on a product is $x$. Find the marked price of the product in terms of $x$.

• A. $0.99x$
• B. $1.11x$
• C. $1.2x$
• D. $1.42x$

Answer 1

The correct option is B $1.11x$

Let the marked price of the product be $y$.

Rate of discount = 10%

So, $x=90$%$\text{of}y=\frac{90}{100}\times y=0.9y$

$\Rightarrow y=\frac{x}{0.9}=1.11x$

$\therefore$ Marked price of the product in terms of $x$ is $1.11x$.
