Hello,
Yes, both the options are open for you. You can become a CA or pursue MBA after your graduation. For both the exams there will be a need of basic level of mathematics that you can learn during your preparation for your respective courses. There are some really good books and online courses available for both, for you to prepare yourself for the exams.
If at all you need more understanding and one-to-one teaching/ learning you can join some good coaching centre present in your locality.
In fact just a matter of fact, there have been CAs who haven't opted for maths in their +2 and now doing MBA from IIM too and are very successful in their careers. So nothing can stop you from achieving anything in life.
Wish you and your daughter all the very best !!
