If 'P @ Q' means 'P is the wife of Q', 'P # Q' means 'P is the son of Q', and 'P $ Q' means 'P is the father of Q', then what is the relationship of K to H in the expression: H # I @ J # K?
Show answer & explanation
Correct answer: B
Explanation
From the diagram:
- (+) → Male
- (−) → Female
- (=) → Marriage
Relationships:
- I(−) is married to J(+) → I is the wife of J
- H(+) is the son of I
- J(+) is the son of K
Reasoning:
H is the son of I, and I is the wife of J ⇒ H is also the son of J.
J is the son of K ⇒ K is the father of J.
Therefore, K is H's grandfather (paternal).
