If, in a competitive exam, the marks obtained by Sam are 19% less than those of Peter, then the marks obtained by Peter are how much percentage more than the marks obtained by Sam? (Correct to two decimal places)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 23.46%.
Let the marks obtained by Peter be 100x
Marks obtained by Sam = 81x
Hence, the required percentage = [(100x - 81x)/81x] × 100
⇒ (19x/81x) × 100
⇒ 23.46%
