```cpp
#include<iostream>
using namespace std;

int sum = 0, num = 0;
for(int i = 0; i < 12; i++) {
cin >> a[i];
}
for(int i = 0; i < 12; i++) {
if(num + 300 < a[i]) {
cout << "-" << (i + 1);
return 0;
}
num += (300 - a[i]);
if(num >= 100) {
sum += (num / 100) * 100;
num = num % 100;
}
}
cout << (sum * 1.2 + num);
}
