Sneha, You have not specified whether you want to inquire about your chances based on percentile secured in JEE MAIN PAPER-1 or JEE MAIN PAPER-2. So, I am going to answer your query taking into consideration that the query is about Paper2 and if your query was different, then you can let me know.

Now, to calculate your expected rank for B.Arch based on the percentile score that you have secured, you can use this formula:

So, (100 - your total percentile score) is the percentage of people ahead of you. Also, 112679 were the number of candidates who appeared for January exam.

Also,note that the ranks will change according to increase or decrease in the number of participants in the next session.

So rank formula is (100 - your total score) X 112679 /100.

Now, according to this formula, your expected rank is around 3560. The admission to any college also depends on your home state and category status and you have not given details about the same.In your case, your chances of getting NIT TRICHY are very small irrespective of your home state and gender as previous year closing rank for ALL INDIA quota for general category was 1075 and the closing rank for general category based on home state quota was 2468. So, going by previous years trends, your chances of making it to NIT THIRUCHIRAPALLI are very small.

However, you have a good percentile and it could give you admission to some other NITs and many other good private institutes and hence you should try for the same.
