A shopkeeper offers the following two discount schemes on the sale of a watch with having marked price of ₹3,600.
- Two successive discounts of 15%.
- A discount of 10% followed by a discount of 20%.
What is the difference between the selling price of the watch in case (1) and case (2)?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. ₹9.
SP (Case 1) = 3600 × (85/100) × (85/100) = 2601
SP (Case 2) = 3600 × (90/100) × (80/100) = 2592
Difference = 2601 - 2592 = 9
