Question

A courier company charges differently for 'Ordinary' booking and 'Express' booking based on the weight of the parcel as per the tariff given below: 

Weight of parcel	Ordinary booking	Express booking
Up to 100 gm	₹ 80	₹ 100
101 to 500 gm	₹ 150	₹ 200
501 gm to 1000 gm	₹ 210	₹ 250
More than 1000 gm	₹ 250	₹ 300

Write a program to input weight of a parcel and type of booking ('O' for ordinary and 'E' for express). Calculate and print the charges accordingly.
