In this question isn’t it needed to evaluate whether the partnership with those persons as to whether or not they are within the prescribed qualifications if they aren’t members of ICAI?
Now a days partnership is allowed with Non-CAs also like CS, CMA, LLB etc
So question is not clear with whom partnership is entered,
Further it is not specified whether prior permission was taken under clause 11 ,because if such permission is available then he can enter into partnership for such business
hence, assumptions are taken and answer is given
