PCM-Physics, Chemistry and Maths (Maths Stream )
PCB-Physics, Chemistry, Biology (Medical Stream)
PCMB-Physics, Chemistry, Maths and Biology

If you are interested in Chartered Accountancy, then obviously you should be opting for commerce. No point in doing science and then proceeding for CA.

70% for PCMB in CBSE is not that bad. For you the career options are countless. You might go opt the following:
1. Engineering (Stream can be chosen according to your interest)
2. Medical Field (MBBS or BMS)
3. B.Sc. (Again stream to be chosen according to your interest)
4. Law (if interested)
Other than that if you want to choose any you can.
In the end you have to decide what your interest lies in.

There is no problem with you pursuing B.Com and MBA after that. You can definitely proceed with the same, but it will be a little difficult for you to catch up as compared to the Commerce students. But, since you seem interested in the course you might catch up fast, if you put in a little bit of extra effort.
