Design a class TBills to calculate the monthly telephone bills and calculate the usage cost of telephone bill as per the following rule:
• Minimum Rs. 200 for upto 100 calls.
• Plus Rs. 0.60 per call for next 50 calls.
• Plus Rs. 0.50 per call for next 50 calls.
• Plus Rs. 0.40 per call for any call beyond 200 calls
PROGRAM IN JAVA:
FILE NAME:TBill.java
import java.util.Scanner;
class TBills{
public static void main(String args[]){
int calls;
double bill;
Scanner sc=new Scanner(System.in);
calls=sc.nextInt();
if(calls<=100)
{
bill=200;
}
else if(calls>100 && calls<=150)
{
calls=calls-100;
bill=200+(0.60*calls);
}
else if(calls>150 &&calls<=200)
{
calls=calls-150;
bill=200+(0.60*50)+(0.50*calls);
}
else
{
calls=calls-200;
bill=200+(0.60*50)+(0.50*50)+(0.40*calls);
}
System.out.println(bill);
}
}
