C++ :

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

int main(){ 
	double n,x,y;
	cin>>n>>x>>y;
	
	cout<<(int)((n * 1000 + y * 10) / (x * 10 + y * 10));

	return 0; 
} 

Pascal :

var a,b,c,d:real;
begin
read(a,b,c);
a:=a*100;
a:=a-b;
d:=trunc(a/(b+c));
d:=d+1;
write(d:0:0);
end.

Java :

import java.util.*;
public class Main {
	public static void main(String[] args){
		Scanner sc = new Scanner(System.in);
		double n = sc.nextDouble();
		double x = sc.nextDouble();
		double y = sc.nextDouble();
		double c = n * 100;
		double b = x + y;
		int a = 0;
		if((n * 100) % (x + y) >= x){
			a =(int) (c / b + 1);
		}else{
			a =(int)( c / b);
		}
		System.out.println(a);
	}
}	

Python :

sr=input().split()
n=float(sr[0])*100
k=float(sr[1])
j=float(sr[2])
m=n//(k+j)
y=n%(k+j)
if y>=k:
    print("%d"%(m+1))
else:
    print("%d"%m)
