2. Design a toll booth Application of Padma bridge. At booth, it will collect the amount of toll from all the vehicles passing through based on the vehicle types (i.e. motorcycle, Buss, Truck, Car, Train etc.) and categories (Govt, Personal, carriage of Goods, Public etc.) and weight of the vehicles etc. Let's assume that Govt wants to encourage its citizen for paying tax regularly. So, it has categorized the taxpayer and provided a card (Platinum, Gold, Silver) to get discount on various public and non-public services. Let's consider that Govt has declared (Platinum->10%, discounts, Gold->8%, Silver->5%) in Tolls Fees, and for Govt vehicles (No Tool fees), for Personal Vehicles-> Govt Official (2%). Design the model and implement the program from OOD and OOP (Inheritance, polymorphism) concept. Also implement a method ie. calculate Toll(Vehicle) which is taking and returning the tollAmount to be paid at toll booth.
