The price of an article has been reduced by 25 %. In order to restore the original price, the new price must be increased by:________?
Correct answer: A. 33 1/3 %
- A. 33 1/3 %
- B. 11 1/9 %
- C. 9 1/11 %
- D. 66 2/3 %
Explanation
After a 25% reduction, the new price is 75% of the original price. To recover the missing 25% using the new price as the base, the required increase is 25/75 × 100 = 33 1/3%. Students may choose 25% because they measure the increase against the original price instead of the reduced price.
