Commerce Eligibility

No, I don't think that you're eligible to get admission in KJ Somaiya College with this parentage.
Good luck.

I think that HA College of Commerce's admission procedure is based on HSC examination.

Depends if that ECA is in DCAC or not
Given the trials and clearing it you can opt for any college that has ECA you are looking for.

I am presuming that you want to take up B.Com or BBA. If you have studied the commerce stream in class 11th and class 12th, then Maths is not compulsory. However, if you are from the Science or Humanities stream, then Maths is compulsory.

Yes, they are but with maths as a compulsory subject in their high school curriculum.

One of my friends is in jet airways and she also passed out from frankinn I believe.

You can get all the necessary details from the above link.

You can do hotel management from a good institute or can opt for management courses such as BMS, BBA or MBA and can get a good job in a reliable MNC.

Although BBA can be done after any stream of study, commerce students would relate to the curriculum more than others. Yes, a student of any stream can do BBA. Of course, science students can pursue BBA. The eligibility criteria includes a minimum of 45% with mathematics and one main subject.
