Hello aspirant,
Hope you are doing absolutely great.
So with regard to your query, in general the fee for any IITs across India will be INR 1 lakh rupees for one semester. On an average for 4 years the fee will be INR 8 lakhs.
Further to get admission into IITs firstly you need to qualify JEE Mains exam and further you need to get qualified in this exam. And after that you should give the JEE Advanced exam. If you score good percentile and rank in JEE Advanced then you will be eligible to get admission into IITs.
