Correct Answer: 23.46%


Solution : Let the marks of Peter be $100$.
$\therefore$ Marks obtained by sam = $\frac{(100-19)}{100}\times 100=\frac{81}{100}\times 100 = 81$
Now, the percentage of marks obtained by Peter is more than that of Sam's
= $\frac{19}{81}\times 100$
= $23.46{\%}$
Hence, the correct answer is 23.46%.
