Hello student you can calculate and get your rank by using this formula
100 - (your total percentile) *112679 /100
In your case your rank must be around - 39,437
I request you to please help me with your category and state so that I can check and provide you the exact information. Cut off vary every year on various factors like the level of question in the entrance examination and total number of applicants in that examination. With this rank its tough to get admission in any government college as we all know that seats are very limited and admission is directly based on merit rank.

Feel free to comment if you have any doubt
Good luck
