I would not say that having maths in +2 is compulsory for attempting CAT. I would rate maths in CAT as a bit advanced version of what you have learned till 10th. If you are aiming for the top colleges, then yes it would be a problem. But for colleges that ask for cutoffs in the range of 50-70, then maths wouldn't be a problem. Even performing average in maths could possibly get you to that score. But ensure that you are able to ace all other sections. If you want to get good score, I suggest you attend a few coaching classes. Brush up on the basics and practice hard.

You have not specified the college you are seeking admission to. Generally, for top MBA college including private ones, you need to achieve a really good score in CAT exam. 90 percentile or more. But a score above 50%ile is considered decent for admission to many private institutions.

The date of birth should be between 2000-2001 to appear for NDA exam.

That's a reasonably good score, with that score your son can quite easily secure admission in Christ University. Provided he qualifies any other requirements laid out by the University.
