#include<iostream>
#include<iomanip>
#include<cstdio>
#include<cmath>
#include<algorithm>using namespace std;int main()
{int n,p;float x,y,s,t=0;cout << "输入：";cin >> n;for(int i=1;i<=n;i++){cin >> x >> y >> p;s = sqrt(x*x + y*y);t += p * 1.5 + 2 * (s *1.0) /50; 	}cout << ceil(t);return 0;
}
//cout << "输入：";

结果：
