Question

Find the marked price when selling price is $Rs.540$, discount is $10$ %.

Answer 1

Selling price $=Rs.540$

Discount $=10\%$

Let $x$ be the marked price.

Therefore,

$x-\frac{10}{100}x=540$

$\Rightarrow \frac{90}{100}x=540$

$\Rightarrow x=\frac{540\times 100}{90}=Rs.600$

Hence marked price is $Rs.600$.
