        Scanner sc=new Scanner(System.in);
        System.out.println("Enter the total cost:");
        tc=sc.nextInt();
        if (tc<=2000)
            r=5;
        else if (tc<=5000)
            r=25;
        else if (tc<=10000)
            r=35;
        else
            r=50;
        dis=r/100*tc;
        ap=tc-dis;
        System.out.println("Amount Payable="+ap);
