    My solution is similar to yours but it is not able to pass the last test case... its giving wrong result for a few sets. Can you please help me understand what I did wrong.

public class Main {
    public static void main(String args[] ) throws Exception {
        /* Enter your code here. Read input from STDIN. Print output to STDOUT */
        Scanner sc = new Scanner(System.in);
        int t = sc.nextInt();
        int n;
        int q1 = 0,q2 = 0,r1 = 0 ,r2 = 0;
        int sum = 0;
        int low;
        for(int ai = 0 ; ai < t ; ai ++){
            n = sc.nextInt();
            int[] a = new int[n];
            for(int i = 0 ; i < n ; i++){
                a[i] = sc.nextInt();
            }
           sum = 0;
           int k =0;
           long sum1 = 1000000000;
           Arrays.sort(a);
           low = a[0];
           for(low = a[0] ; low >= 0 ; low--){
             sum = 0;
           for(int i = 0 ; i < n ; i++){
               k = a[i]-low;
               //System.out.println(low + " " + a[i]);
               q1 = k/5;
               r1 = k % 5;
               q2 = r1/2;
               r1 = r1 % 2;
               sum = sum + r1 + q2 + q1;
               //System.out.println(a[i] + "---" + q1 + " " + q2 + " " + r1);
           }
           //System.out.println(sum + "");
           if(sum < sum1)
            sum1 = sum;
           }
           System.out.println(sum1); 
        }
    }
}
