John bought a laptop at 25% discount on the marked price. If he paid ₹ 28,473 for the laptop, what was its marked price?

Discount = 25%

Selling Price (after discount) = ₹ 28,473

​$$\text{Selling Price} = \text{Marked Price} \times \left(1 - \frac{\text{Discount}}{100}\right)$$​​

Solution: 

Substituting the value in formula;

​$$28473 = \text{Marked Price} \times \left( 1- \frac{25}{100}\right) \\ \ \\ 28473 = \text{Marked Price} \times \left( \frac{75}{100}\right) \\ \ \\ \implies \text{Marked Price} = \frac{ 28473 \times 100}{75} = 37964$$ 

Thus, the marked price is Rs. 37,964.
