AC代码：
```
#include<iostream>
#include<cstdio>
using namespace std;
int n,n1,p1,n2,p2,n3,p3,t1,t2,t3,boss;
int main(){
scanf("%d%d%d%d%d%d%d",&n,&n1,&p1,&n2,&p2,&n3,&p3);
t1=!(n%n1)?n/n1*p1:(n/n1+1)*p1;
t2=!(n%n2)?n/n2*p2:(n/n2+1)*p2;
t3=!(n%n3)?n/n3*p3:(n/n3+1)*p3;
boss=t1;
if(t2<boss)boss=t2;
if(t3<boss)boss=t3;
printf("%d",boss);
return 0;
}
```
错误原因：当``boss``值修改后，不能再与```t3```比较。
