A shopkeeper marked a price on an article so that he gets 50% profit. After 2 months, the sale of the article reduced. So, he decided to sell the same article with a profit of 20%. What percentage of discount does he announce to get only 20% profit? | UPSC CAPF 2026 Q No 65

Accepted Answer: (D) 20

Topic Covered: Quantitative Aptitude and Reasoning

Key Concept: Mathematical relationships, counting and logical analysis

Marked price is 50% above cost price, while a 20% profit fixes the selling price at 120% of cost. Comparing selling price with marked price gives the required discount.

The key is to apply the central fact, formula, definition or relationship tested in the question and then eliminate alternatives that do not satisfy it.
