If P $ Q means P is the brother of Q; P # Q means P is the mother of Q; P * Q means P is the daughter of Q. If the expression is A # B $ C * D, who is the father? MCQ with Answer and Explanation

Explanation:
'The wife of my husband' is Rita herself. Her daughter's brother is her own son. Thus, the man on the stage is Rita's son.

Explanation:
E is B's daughter and D is E's brother. Therefore B is D's parent, and A, being B's mother, is D's grandmother.

Explanation:
P ÷ Q → P mother of Q. Q – S → Q father of S. S + K → S brother of K, so K is also son of Q. K – T → K father of T. T × R → T husband of R. K is father-in-law of R (true). S is brother of K, T's father (true). Q is father of K, so father of T's father (true). P is mother of Q, so P is grandmother of K, not mother of K's mother. Hence C is incorrect.
