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. 9 1/11 %
- C. 11 1/9 %
- D. 66 2/3 %
- E. None
Explanation
After a 25% reduction, the new price is 75% of the original price. To restore it, the required increase is (100% - 75%)/75% x 100% = 25/75 x 100% = 33 1/3%. The likely trap is 25%, which measures the reduction against the original price rather than the reduced price.
