Question

In a library, books were given to members for two weeks. Upon late return, they were charged at a rate as per following chart:

Days Late (D)	Late Fine in ₹
<=3	₹ 4 per day
Next 3 days	₹ 8 per day in this range
Next 3 days	₹12 per day in this range
Beyond 9 days	₹ 15 per day in this range

Answer 1

import java.util.*;
class clLibrary
{
    void main()
    {
         Scanner sc = new Scanner(System.in);
         int days = 0, fine = 0;
         System.out.print("Days late :: ");
         days = sc.nextInt();
         if(days<=3
         {
             fine = 4;
         }
         else if(days <= 6)
         {
             fine = 4 + (days - 3) * 8;
         }
         else if(days <=9)
         {
             fine = 4 + 8+ (days – 6) * 12;
         }
         else
         {
             fine = 4 + 8 + 12 + (days -9) * 15;
         }
         System.out.print(" For " + days + " days late, fine is : "+ fine );
    }
}

Output:

Days late :: 7

For 7 days late, fine is: 24
