A pair of trousers has a marked price of ₹1,200. A shopkeeper offers a 20% discount on the trousers and then another 30% discount on the original price. How much will you ultimately have to pay?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e ₹672.
Selling price = (1 − first discount⁄100)(1 − second discount⁄100) × Marked price
⇒ Selling price = (1 − 20⁄100) × (1 − 30⁄100) × 1200
⇒ Selling price = (1 − 1⁄5) × (1 − 3⁄10) × 1200
⇒ Selling price = (4⁄5) × (7⁄10) × 1200
⇒ Selling price = Rs. 672
