/* Calls variable holds the number of calls entered */

calls = s.nextInt();

public double billing()

{

     if (calls <= 100)  /* Rs. 100 for first 100 calls */

            money = 100;

     else if (calls > 100) && (calls <= 150)  

/* Additional 50 calls also charged at Rs.1 per call */

            money = 1*(calls);

else if (calls > 150)

             /* After 150 calls , charge Rs. 1.50 per call */

            money = 150 + (calls-150)* 1.50;

return money;

}

public static void main(String[] args) {
