Hii,do not worry i am here to help you according to your query.The maximum pay package offered to students this year was 21 lakh per annum and the minimum - 7 lakh per annum.(this is in all IIT)An average of 10 to 15 lakh per annum is usually the package but then again it depends on the student; the extra effort put in by that individual is eventually what companies look for.An M.Tech course requires 7.8 lakhs (for 2019 batch), which I presume you already know.

Hope,this information helpful for you.Goodluck.
