Hi Ajay,
You can go through the previous years' DU cut-offs for all courses and colleges here: https://www.shiksha.com/du-cut-off-trends-for-past-years-article-12697-1

Dear Ayesha,
Yes with this score you can get admission in B.com in delhi university, since cutoffs for B.Com are not so high hence you can get.
All the very best

Dear Sauhaard,
With this score you can easily get admission in B.com in DU, but if you are looking for admission in B.com Hons course then you may find it with 30% chances of admission if cutoffs goes above 5.
Apart from Du you can look for admission in IP university, Jamia millia, Amity noida
All the very best

you can get direct admission if your 12th percentage is 80%+

First of all congratulations on securing such a good scoring. Yes you may get, I stress upon may because, it depends on the scores submitted to SPA, Delhi. If there are higher ranks submitted, it will be difficult for you to get in there, but if luck favors you and lower ranks than yours submit then surely you will get the seat in your name.

You will get a good college. But as you are from outside Delhi
I'll advice you to check http://ipuadmissions.nic.in/ for rank cutoffs.
Top Ip colleges are
1.USMS
2.MAIT
3.DIAS
4.RDIAS

Bachelors in DU is not called BBA, it's BBS/BBA(FIA)/BBE and these are the best among the choices.
MBA in India and abroad are quite similar. it depends upon individual choices.

FMS and LBSIM and IMI are most preferred under management quota.
