A customer purchases a product for ₹550 after a 12% discount. What was the…

For any discount problem, the selling price (SP) equals the marked price (MP) reduced by the discount percentage: SP = MP × (1 − discount% / 100). To find the marked price when the selling price and discount percentage are known, this relation is rearranged as MP = SP ÷ (1 − discount% / 100).

1. A 12% discount means the customer pays 88% of the marked price, so the relation becomes SP = MP × 0.88.

2. Substituting the given selling price: 550 = MP × 0.88.

3. Solving for MP: MP = 550 ÷ 0.88 = 625.

Checking the result: applying a 12% discount to ₹625 gives 625 × 0.88 = ₹550, which matches the price the customer actually paid, confirming the marked price is correct.

The marked price of the product was ₹625.
