If ‘P # Q’ means ‘P is the brother of Q’, ‘P $ Q’ means ‘P is the father of Q’ and ‘P % Q’ means ‘P is the mother of Q’, then in the expression G # H $ J % K, how is H related to K?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Maternal grandfather
Read the expression one symbol at a time. The father of one’s mother is one’s maternal grandfather.
G # H: G is the brother of H
H $ J: H is the father of J
J % K: J is the mother of K
H is the father of K’s mother J: H is K’s maternal grandfather
Why the other options are incorrect
Option (1) Paternal grandfather — Incorrect. H is the father of K’s mother, not of K’s father.
Option (2) Father — Incorrect. K’s parent in the chain is J, the daughter of H.
Option (4) Maternal uncle — Incorrect. A maternal uncle is the mother’s brother; H is the mother’s father.
