Answer to your question as it is: I am not giving any salary to a CS graduate or any graduate for that matter from IIT Delhi or anywhere else because I don't own a company.
If your question asks for my opinion on "How much salary should a CS graduate from IIT Delhi get?" My answer is, "I don't care." You should do whatever makes you happy, whether it is salary or work or the company or city. Make your own decision based on what is important to you.
