| Next 200 units | Rs. 1 per unit |
| Above 300 units | Rs. 2.50 per unit |

public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter Units Consumed: ");
int units = in.nextInt();
double amt = 0.0;
if (units <= 100)
amt = units * 0.8;
else if (units <= 300)
amt = (100 * 0.8) + ((units - 100) * 1);
else
amt = (100 * 0.8) + (200 * 1.0) + ((units - 300) * 2.5);
amt += 500;
System.out.println("Units Consumed: " + units);
System.out.println("Bill Amount: " + amt);
}
