3 Perl

use List::Util qw( max sum );
$n = int(<STDIN>);
@lst = (split / /, <STDIN>);
($max, $sum) = (max(@lst), sum(@lst));
printf("%.2f\n", $sum / $n * 100 / $max);

4 PHP

<?php
fscanf(STDIN,'%d',$n);
$scores = explode(' ',rtrim(fgets(STDIN)));
$max = max($scores);
$sum = array_sum($scores);
echo $sum/$n*100/$max;

5 Python

import sys
N = int(sys.stdin.readline())
lst = list(map(int,sys.stdin.readline().split()))
M = max(lst)
S = sum(lst)
print( S / N * 100 / M )
