Question 1
If X+Y means X is the mother of Y; X-Y means X is the brother of Y; X%Y means X is the father of Y and X x Y means X is the sister of Y, which of the following shows that A is the maternal uncle of B?
Explanation
A-C+D x B is read as: A-C (A is the brother of C), C+D (C is the mother of D), D x B (D is the sister of B).
Since C is the mother of D, and D is the sister of B, C is also the mother of B (D and B share the same mother, C).
A is the brother of C, who is B's mother -- so A is B's maternal uncle.
Since C is the mother of D, and D is the sister of B, C is also the mother of B (D and B share the same mother, C).
A is the brother of C, who is B's mother -- so A is B's maternal uncle.
Question 2
B is the brother of A, whose only sister is the mother of C. D is the maternal grandmother of C. How is A related to D?
Explanation
A's only sister is C's mother. D, the maternal grandmother of C, is therefore the mother of C's mother -- i.e., the mother of A's sister, who is also A's own mother (siblings share the same mother).
So D is A's mother, making A the daughter of D.
So D is A's mother, making A the daughter of D.

Question 6
Each of these questions is based on the following information:
P % Q means P is the father of Q.
P @ Q means P is the sister of Q.
P $ Q means P is the brother of Q.
P * Q means P is the wife of Q.
In the expression A % B @ K * H % P, how is B related to P?
P % Q means P is the father of Q.
P @ Q means P is the sister of Q.
P $ Q means P is the brother of Q.
P * Q means P is the wife of Q.
