Hotel / Hospitality Management Eligibility

No, you wouldn't be deemed eligible for any such scholarship, with that rank and Amity University is not affiliated to NCHMCT.

Bachelor Science in Hotel Management-
B.Sc. In Hotel Management is a 3-year full-time undergraduate course, the minimum eligibility for which is higher Secondary Certificate (10+2 qualification) with a minimum aggregate score of 50% in best four relevant subjects. So, you can apply for it.
Best of luck.
Regards.

Yes, you can. However, it is a waste of time if you take it after B.Tech. It's better that you take BHM after +2. There are a few institutes in Visakhapatnam. Sun Institute is the better one.

Candidate must have passed 10+2 to get eligible for the hotel management courses. You can also check the eligibility criteria on its official website.

No age limit has been mentioned for this course. You can probably contact the enquiry desk of the institute directly https://www.isb.edu/contact-us

By the time I'm reading this question, it is already been 11 months and you're more than eligible to apply just here are some of my personal college suggestions:
Central Government IHMs in 1-tier cities only. Oberoi-STEP
Vedatya Institute-Gurgaon
IHM-Aurangabad. All the very best.

For candidates from general and OBC categories, upper age limit is 22 years as on 1.7.2018, therefore, only those candidates whose date of birth falls on or after 1.7.1996 are eligible to apply.
