Answer: 15%.
The idea
Discount is always a percentage of the marked price, whereas profit is a percentage of the cost price. Confusing the two bases is the commonest slip in this chapter.
Shortcut. The sale keeps 680/800 = 85% of the marked price (8 × 85 = 680), so the discount is 15%.
Common trap. 17.5% — dividing the ₹120 discount by the ₹680 sale price (≈17.6%) instead of by the ₹800 marked price.
