Using the coded relationships below, answer the question. 'E + B' means 'E is the husband of B'. 'E - B' means 'E is the daughter of B'. 'E $ B' means 'E is the father of B'. 'E # B' means 'E is the mother of B'. If N + D # Z $ B, how is N related to B?

  1. N is the paternal grandfather of B
  2. N is the mother-in-law of B
  3. N is the paternal grandmother of B
  4. N is the maternal grandmother of B

Correct answer: N is the paternal grandfather of B

Solution

N + D: N is the husband of D. D # Z: D is the mother of Z, so N (D's husband) is the father of Z. Z $ B: Z is the father of B. Therefore N is the father of Z who is the father of B, making N the paternal grandfather of B.
