Make a gap certificate and take the admissions using the certificate.

There's no college in any city which offers a Bachelor degree after 10th. So, you need to complete you 12th first.

You have really good academic scores. There are many colleges where you can apply like:
1) BIMM
2) ISBS
3) ITM Navi Mumbai
4) IIMP, etc.
I'm currently studying in BIMM executive (marketing)

Yes, there are bright chances of getting call from this college but still, I would suggest you to fill form for other colleges as well for backup like:

2) ISBS

For doing MBA, one must complete UG with 50%.

The minimum criteria to apply for BIMM is 50% in graduation, so you are eligible to apply. But you need to prepare well for the GDPI. More weightage is given to GD-PI.

For Diploma, you need to be class 12th pass so just clear it first then go for any course.

You can fill the registration form as there is a chance, though a bit less, and appear for GD-PI as selection depends on GD-PI as well along with other credentials.
All the best.
