一个公式完事

代码

#include<bits/stdc++.h>
using namespace std;
#define ll long long 

int main(){
    ios::sync_with_stdio(false);
    cin.tie(0);
    cout.tie(0);
    //freopen("in.txt","r",stdin);
    ll t,s,a,b,c;
   cin>>t;
   while(t--){
    cin>>s>>a>>b>>c;
        ll sum=0;
        sum=s/c+s/c/a*b;
        cout<<sum<<endl;
   }
    return 0;
}
