Indian Railways — parking fees in secunderabad railway station

Address:

Hyderabad, Andhra Pradesh, 500001

I wanted to understand the basis of defining the parking charges in railway stations. When i tried to compare the parking fees in secundrabad railways station with any other parking facility it at least 200 % higher. They are charging a sum of rupees 120 for bike for 12 hours. They have openly displayed the price charts, but these prices are more than railway ticket prices if you travel for 12 hours in general.
