Solution

Sure, let's break down the problem step by step:

Problem Understanding

Chef has collected N notes of Rs. 2000 each to pay his college fees. However, the Rs. 2000 notes have been banned, and now Chef needs to pay the same amount using Rs. 500 notes only. We need to determine how many Rs. 500 notes Chef will need.

Steps to Solve the Problem

  1. Calculate the Total Amount Chef Has:

    • Each Rs. 2000 note contributes Rs. 2000.
    • If Chef has N notes, the total amount is N * 2000.
  2. Convert the Total Amount to Rs. 500 Notes:

    • Each Rs. 500 note contributes Rs. 500.
    • To find out how many Rs. 500 notes are needed, divide the total amount by 500.

Formula

Given N notes of Rs. 2000:

  • Total amount = N * 2000
  • Number of Rs. 500 notes needed = (N * 2000) / 500

This simplifies to:

  • Number of Rs. 500 notes needed = N * 4

Example

Let's go through the provided example:

  • Input: N = 4
  • Total amount = 4 * 2000 = 8000 rupees
  • Number of Rs. 500 notes needed = 8000 / 500 = 16

Implementation

Let's write the code to solve this problem:

def calculate_500_notes(N):
    # Calculate the number of Rs. 500 notes needed
    return N *
