SSC CGL (Prelims) Maths: Discount questions with solutions

Q1. A bronze article with a marked price of ₹1,000 is sold during a festive season sale after three successive discounts of 20%, 30%, and 10%. What amount (in ₹) will a customer pay if she buys the article during the festival season?

1. ₹508
2. ₹564
3. ₹504
4. ₹496

Answer: ₹504

For successive discounts, the selling price is found by multiplying the marked price by the remaining percentages after each discount. Here, the price becomes 1000 × 0.8 × 0.7 × 0.9 = 504. So the customer pays ₹504.
