The marked price of an article is Rs. 1500. After allowing a certain discount, it is sold at Rs. 1320. Find the discount percentage.
Appeared in: DSSSB - 29 August 2019 (Shift-1)
Explanation
- The discount is the difference between the marked price (Rs. 1500) and the selling price (Rs. 1320), which amounts to Rs. 180.
- The discount percentage is calculated by dividing the discount amount by the original marked price and then multiplying by 100 to express it as a percentage.
- The calculation is (Rs. 180 / Rs. 1500) × 100, which equals 12%.
Why Other Options Were Wrong
- Option A: An 18% discount on Rs. 1500 would be Rs. 270. This would result in a selling price of Rs. 1230 (1500 - 270), which does not match the given selling price of Rs. 1320.
- Option B: A 10% discount on Rs. 1500 would be Rs. 150. This would result in a selling price of Rs. 1350 (1500 - 150), which is higher than the given selling price of Rs. 1320.
- Option D: A 15% discount on Rs. 1500 would be Rs. 225. This would result in a selling price of Rs. 1275 (1500 - 225), which does not match the given selling price of Rs. 1320.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Calculating discount percentage from marked price and selling price as background academic context rather than a clinical decision trigger.
- While not a clinical topic, understanding percentages is a fundamental mathematical skill essential for various nursing calculations, including drug dosages, IV drip rates, and interpreting statistical data in research.
- Basic financial literacy, including concepts like discounts and percentages, is important for personal finance management for students and professionals alike.
- What if the question asked for the selling price after a 20% discount? The calculation would be: Discount = 0.20 × 1500 = 300. Selling Price = 1500 - 300 = Rs. 1200.
How to Approach the Question
- First, carefully read the question to identify the given values: the Marked Price (MP) is Rs. 1500 and the Selling Price (SP) is Rs. 1320.
- Recall the formula to find the discount amount: Discount = Marked Price – Selling Price.
- Calculate the discount amount by subtracting the SP from the MP: 1500 - 1320 = 180.
- Next, recall the formula for the discount percentage: Discount % = (Discount / Marked Price) × 100.
- Substitute the values you have: (180 / 1500) × 100.
- Perform the calculation to find the final answer, which is 12%.
