@[lyxsunday](/user/461676) `n % a == 0` 的时候就不用加一

@[bxnya_miana](/user/297675) 这样?
```cpp
if(n%a==0)
{
t=n/a;
}
else
{
t=n/a+1;
}
```

我按你的改了下：
```cpp
#include<iostream>
using namespace std;
int n,a,b,t,ans=100000000;
int main()
{
cin>>n;
for(int i=1;i<=3;i++)
{
cin>>a>>b;
t=n/a;
while(a * t < n){
t++;
}
ans=min(ans,b*t);
}
cout<<ans;
return 0;
}
```
