A man buys an article for 10% less than its value and sells it for 10% more than its value. His gain or loss percent is:________?
Correct answer: D. more than 20% profit
- A. no profit, no loss
- B. 20% profit
- C. less than 20% profit
- D. more than 20% profit
Explanation
Let the article's value be V Rs. The cost price is 90% of V, or 0.9V Rs, and the selling price is 110% of V, or 1.1V Rs, so the gain is 0.2V Rs. Gain percent = (0.2V / 0.9V) x 100 = 22.22%, which is more than 20%; students often choose 20% by subtracting the two percentages without dividing by cost price.
