1)In an Internet Café customers are charged as follows for browsing:
• First hour or part of an hour – 40 Rupees
• Next four hours – 30 Rupees per hour or part of an hour
• For each hour after that – 20 Rupees per hour or part of an hour
Write a C program using the “Else-If” statement such that when the user enters the number of hours of Internet Connection, the program displays the amount to charge from the customer.
Example: If a user browsed the Internet 3 hours and 15 minutes,
Charge = 40 Rs for the 1st hr+30*3 Rs for the next 2 hr and 15 min
2)A shop sells electrical appliances such as TVs, Fridges, Fans, and Washing Machines etc. In case the customers cannot pay the full amount to purchase an appliance the shop supports easy payment schemes, such that the customers can make the payments via monthly installments.

1 6 months 6 6
2 1 year 12 8
3 1.5 years 18 10
4 2 years 24 12
Monthly Installment = (Price of the Appliance + Interest) / No. of Installments
