Explanation:

import java.util.*;

public class abc

{

   public static void main (String[] args) {

       

       Scanner sc =new Scanner(System.in);

       

       int no_input=sc.nextInt();

       sc.nextLine();

       String input[]=new String[no_input];

       String input1[][]=new String[no_input][3];

       

       for(int i=0;i<no_input;i++)

       {

           input[i]=sc.nextLine();

           input1[i]=input[i].split(",");

       }

       

       int discount[]=new int[no_input];

       

       for(int i=0;i<no_input;i++)

       {

           discount[i]=(Integer.parseInt(input1[i][2])*Integer.parseInt(input1[i][1]))/100;

       }

       

       int min_dis=32767;//highest value that can be stored in Integer

       String output=new String();

       

       for(int i=0;i<input.length;i++)

       {

           if(min_dis>discount[i])

           {

               min_dis=discount[i];

           }

       }

       

       for(int i=0;i<input.length;i++)

       {
