A electricity board charges the following rates to domestic users to charge large consumption of energy. For first 100 units - 40paise/ unit , for next 200 units – 50paise/ unit , for next or beyond 300 units – 60paise /unit, if the total bill is more than Rs.250 then an additional charge of 15% is added to the bill. Write a program that read the names of the users and number of units consumed and print the charges with names.

class Charge

   {

     public static void main(String[] args)

      {

       float p;

       int units=Integer.parseInt(System.console().readLine("enter the units="));

       String userName=System.console().readLine("entr the user name=");

        if(units<=100)

          {

            p=units*.4f;

            System.out.println("rs="+p);

           }

          else

            {

             if((units>100)&&(units<=300))

             {

                p=(100*.40f)+((units-100)*.50f);

                System.out.println("rs="+p);

             }

            else

               {

                 p=(100*(40/100f))+(200*(50/100f))+((units-300)*(60/100f));

                 System.out.println("rs="+p);

               }

             }

          if(p>250)

             {

               p=p+p*(15/100f);

               System.out.println("Bill="+p);

             }

        System.out.println("userName="+userName+" & Bill="+p);

      }
