Which of the following means `Q is the paternal uncle of K'?
A) K × P ÷ M × Q
B) K × B ÷ N × Q ×D
C) Q × L ÷ R × K
Only (B)
(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 or 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.
