Hello Ravindra,
Yes, check for IGNOU, U18, MGU, KSOU etc.

After completing your Diploma, you can go for engineering or try to get a decent job.

Yes, you can do that. Mathematics is not required.

Both are different streams, so comparing them makes no sense. Figure out what you enjoy studying most, figure out your skills - Do you like decision making? Do you have good analytical skills or do you like research oriented work? Take a psychometric test and check your aptitude. If you want an MBA later again, there is no point doing B.Sc. Choose the field you really like.

You have a very fair chance in PGDM-IB which runs parallel to PGDM.

Yes, you definitely can. Go for higher studies. You can get a good job.
