1. Develop a program which accepts a number (an amount of money to be paid by a
customer in rupees) entered from the keyboard. If the amount is greater than or equal to
1,000 rupees, a 5% discount is given to the customer.Then display the final amount that
thecustomerhastopay.
2. Modify the program for the question 1 so that it displays the message “No discount…”
iftheamountislessthan1,000.
3. Write a program that reads the marks obtained for a given subject and display the given
message.
• 0-50=>“Fail”
• 51-100=>“Pass”
4. Write a python program to implement the Number Guessing Game. In this game the
computer chooses a number between 1 and 10, and the player tries to guess the number
in one attempt. Each time the player enters a guess, the computer tells him whether the
guess istoohighortoolow.
