Which of the following means 'A is the paternal uncle of K'?
1. K × P ÷ M × A
2. K × B ÷ N × A × D
3. A × L ÷ R × K
4. Both 1 and 2
Sol: Option 2 Explanation:
‘K × P ÷ M × A’ means ‘K is the brother of P whose father is M, who is the brother of A’. Thus, K is the child of M, who is the brother of A. So, A may be the paternal uncle or aunt of K.
‘K × B ÷ N × A × D’ means ‘K is the brother of B, whose father is N, who is the brother of A, who in turn is the brother of D’. Thus, N is the father of K, and A is the brother of N. So, A is the paternal uncle of K.
‘A × L ÷ R × K’ means ‘A is the brother of L whose father is R, who is the brother of K’. Thus, R is the father of A and R is the brother of K. So, K may be the paternal uncle or aunt of A.
Thus, only (2) represents the correct relation. Hence, the answer is (2)
