Appeared in: SGPGI Nursing Officer-2024
Explanation
- The discount is the difference between the marked price (Rs. 840) and the selling price (Rs. 714), which is Rs. 126.
- The discount percentage is calculated by dividing the discount amount by the marked price and multiplying by 100.
- Calculation: (126 / 840) × 100 = 0.15 × 100 = 15%.
Why Other Options Were Wrong
- Option A: A 10% discount on Rs. 840 would be Rs. 84. The selling price would then be Rs. 756 (840 - 84), not Rs. 714.
- Option C: A 20% discount on Rs. 840 would be Rs. 168. The selling price would then be Rs. 672 (840 - 168), not Rs. 714.
- Option D: A 25% discount on Rs. 840 would be Rs. 210. The selling price would then be Rs. 630 (840 - 210), not Rs. 714.
