NIT

Hello Mahima,
Eligibility is minimum 75% for general catagory candidates in NIT's. Hence this is ruled out. I am attaching a link that will predict college for you.

No, but few deemed universities are offering food technology courses. Few are there in Andhra Pradesh like JNTU, Kakinda is one among them offering food technology with placements and another college in Longowal University with internship program for two and half years course along with campus placements.

I think you are not mentioning your correct rank. If your general rank is 50k then your ST rank can't be 16k. It will be under 1500.

Hello Jothi!
To get B.Arch course in NITs, you need to have a good score in JEE Mains paper 2. All NITs make admissions only based on your score in JEE Mains paper 2 exam (for architecture). You also need to have atleast 75% in your board exams.

Yes, you can get admission in Gujarat University. For more information, you can contact www.jacpcldce.ac.in.

With this score and rank in JEE Mains I'm sorry to say there are very slim chances of getting the college that you have mentioned above and for the advance there are chances but they are very less.
It will be better to wait for the result and then think about it.
For the college that you will get with your rank you can follow the link in the end of the answer.
