Correct
(A) ‘K × P ÷ M × Q’ means ‘K is the brother of P whose father is M, who is the brother of Q’. Thus, K is the child of M, who is the brother of Q. So, Q may be the paternal uncle of aunt of K.
(B) ‘K × B ÷ N × Q × D’ means ‘K is the brother of B, whose father is N, who is the brother of Q, who in turn is the brother of D’. Thus, N is the father of K, and Q is the brother of N. So, Q is the paternal uncle of K.

(A) ‘K × P ÷ M × Q’ means ‘K is the brother of P whose father is M, who is the brother of Q’. Thus, K is the child of M, who is the brother of Q. So, Q may be the paternal uncle of aunt of K.
(B) ‘K × B ÷ N × Q × D’ means ‘K is the brother of B, whose father is N, who is the brother of Q, who in turn is the brother of D’. Thus, N is the father of K, and Q is the brother of N. So, Q is the paternal uncle of K.
(C) ‘Q × L ÷ R × K’ means ‘Q is the brother of L whose father is R, who is the brother of K’. Thus, R is the father of Q and R is the brother of K. So, K may be the paternal uncle or aunt of Q.
Thus, only (B) represents the correct relation.

If ‘P × Q’ means ‘P is the daughter of Q’; ‘P + Q’ means ‘P is the father of Q’; ‘P ÷ Q’ means ‘P is the mother of Q’ and ‘P – Q’ means ‘P is the brother of Q’, then in the expression A ÷ B + C – E × F, how is A related to F ?
Correct
A ÷ B + C – E × F means A is the mother of B, who is the father of C, who is the brother of E, who is the daughter of F. Thus, C and E are the children of B and F. Since B is the father, so F is the mother of C and E i.e. F is the wife of B. A is the mother of F’s husband i.e. A is the mother-in-law of F.
Incorrect
A ÷ B + C – E × F means A is the mother of B, who is the father of C, who is the brother of E, who is the daughter of F. Thus, C and E are the children of B and F. Since B is the father, so F is the mother of C and E i.e. F is the wife of B. A is the mother of F’s husband i.e. A is the mother-in-law of F.
