A number was mistakenly increased by 25% instead of decreased by 20%. By what percent is the final result more than the CORRECT value?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 56.25%.
Let number = 100
Correct value after 20% decrease = 80
Mistaken value after 25% increase = 125
Increase over correct value = 125 - 80 = 45
Required% = × 100 = % = 56.25%
