```
#include <bits/stdc++.h>
using namespace std;
int llast,sum,use,save;
int main()
{
for (int i=0; i<12; i++)
{
scanf ("%d",&use);
sum = 300 - use + llast;
if (sum < 0)
{
printf("%d", -i - 1);
return 0;
}
save += sum / 100 * 100;
sum = sum - sum / 100 * 100;
llast = sum;
}
float a = save*1.2;
printf ("%d",int(a)+llast);
return 0;
}
