The exact numbers for fee and cancellation with all the details and deadlines will mentioned in your offer letter.
But just to ballpark everything in case you are expecting to receive an offer letter, you should pay the entire fee within 7 days of receiving it.
It’s just an estimate but I think you’ll need to pay around 3 lakhs. And you’ll get be refunded everything on cancellation of admission except the admission fee which is I guess around 10 thousand.
