A man gains 20% by selling an article for a certain price. If the sells it at double the price, the percentage of profit will be:________?
Correct answer: D. 140
- A. 40
- B. 100
- C. 120
- D. 140
Explanation
A 20% gain means the original selling price is 120% of cost price, or Rs. 1.20C for cost Rs. C. At double that price, selling price is Rs. 2.40C, so profit is Rs. 1.40C and profit percent = (1.40C/C) x 100 = 140%. The likely wrong choice is 120%, which states the new selling price as a percentage of cost rather than the profit percentage.
