Thank You sanjana.You are very smart.
I got AC at all.

#include<stdio.h>
int main()
{
unsigned long p,q,n,count=0,grade[10000],sum=0,index,ca;
float avg,percent,t;

scanf("%lu\n",&ca);
for(index=1;index<=ca;index++)
{
scanf("%lu\t",&n);
if(n<=1000)
{
for(p=1;p<=n;p++)
{
scanf("%lu",&grade[p]);
sum+=grade[p];
avg=sum/n;
}
for(p=1;p<=n;p ...
