C :

#include<stdio.h>
int main()
{
	int m,n,s,c;
	scanf("%d%d",&m,&n);
	s=n/m;
	c=5*s;
	printf("%d",c);
	return 0;
}

C++ :

#include <iostream>
using namespace std;

int main(){
	int x;
	int y;
	cin>>x;
	cin>>y;
	cout<<y/x*5<<endl;
}

Pascal :

var
  n,m,a,b:longint;
begin
  read(a,b);
  n:=(b div a)*5;
  write(n);
end.

Java :

import java.util.*;
public class Main{
	public static void main(String args[]){
		Scanner sc = new Scanner(System.in);
			int m = sc.nextInt();
			int n = sc.nextInt();
			System.out.println(5*(n/m));
	}
	}

Python :

s = input().split()
print(int(s[1])//int(s[0])*5)
