Read the following information carefully to answer the question given below:
  1. ‘A × B’ means ‘A is the brother of B’;
  2. ‘A ÷ B’ means ‘B is the father of A’;
  3. ‘A + B’ means ‘A is the sister of B’;
  4. ‘A – B’ means ‘A is the mother of B’;
  1. 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
    1. Only (a)
    2. Only (b)
    3. Only (c)
    4. Both (a) and (b)

    3. (iii) only
    4. Only (iii) and (iv)
    5. None
Solution
  1. (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 many be the paternal uncle or aunt of Q. Thus, Only (b) represents the correct relation. Hence the answer is (b).
  2. Clearly, we used only (i) and (ii) toe answer the above question, while (iii) and j(iv) are superfluous.Hence, the answer is (d).
 
Example-3
If ‘P + Q’ means ‘P is the father of Q’ ‘P × Q’ means ‘P is the brother of Q’; ‘P - Q’ means ‘P is the mother of Q’, then which of the following is definitely true about C - A + B?
  1. B is the son of A.
  2. A is the son of C.
  3. B is the father of A.
