Hey Shruthi,
Hope you are doing well. Perhaps you may be asking about the fees for the K-CET alloted colleges as you have tagged it. It depends on mainly two things:
The fee structure had changed last year and there are chances that it will be further increased this year, as many colleges are protesting for the hike in fees. So it would be better if you refer to the previous year fee structure for K-CET so that you may get some idea about it. You can search in Google for "K-CET fee structure 2018" and click on the PDF among the results.
All the best
