IITM HELPING HAND

The company rents out vehicles to customers. When a customer

requests for a car, the company lets them know what types of

vehicles are available and the charges for each car.

For every car, there is per hour charge and a per kilometre charge. A

car can be rented for a minimum of 4 hours. The amount chargeable

to a customer is maximum of (per hour charge for the car times the

number of hours used, and per kilometre charge times the number of

kilometres run) subject to a minimum amount decided by the charge

for 4 hours use of the car.

An AC vehicle of a particular category is charged 50% more than a

non-AC vehicle of the same category.

There is a charge of rupees 150 for every night halt regardless of the

type of the vehicle.

When a customer books a car, he has to deposit an advance amount.

The customer also informs the company when he expects to return

the car. When the car is returned, depending on the usage, either the

customer is refunded some amount, or he has to pay additional

amount to cover the cost incurred.

In addition to automating the above activities, the company wants to

collect statistics about various types of vehicles such as average

amount of money spent on repairs for the car, average demand,

revenue earned by renting out the car, and fuel consumption of the

car. Based on these statistics, the company may take a decision about

which vehicles are more profitable. The statistics can also be used to

decide the charge for different types of vehicles.
