If the selling price is Rs 728 after getting a discount of 9%, what was the marked price?
Let Marked Price = Rs. $$x$$
Selling price = Rs. 728
Discount % = $$\frac{(x - 728)}{x} \times 100 = 9$$
=> $$\frac{x-728}{x} = \frac{9}{100}$$
=> $$100x - 72800 = 9x$$
=> $$100x - 9x = 91x = 72800$$
=> $$x = \frac{72800}{91} = Rs. 800$$
