Package depends mainly on the organizations visiting a particular college and the profile they are offering. A rough idea about the package you can have from the average package in past years. You can check student reviews and placement reports if any. For a college in the ranks of 30-40s package for HR is about, 7-8 LPA (an estimate). Also have a look at this article-

These 2 colleges provide distance agribusiness management for 2 years:-

M.Com in banking and insurance.

You can't be an executive chef with a PG certificate. I would suggest you to get into any Kitchen management trainee post with any prominent hotel group after your BHM. And after that plan your PG.

Anyhow, if you have good grades in B.Tech and you have passed entrance exam like CAT, MAT, etc. With flying colours then directly, you can go for Masters. If you have backlog in your graduation and not appeared for any entrance exam then you take up a job which will give you work experience and even a year or two to prepare for entrance exam. Hope this helps you. Be free to share any problem you have.
All the best for your bright future!
