X % Y means X is the Father of Y.
X @ Y means X is the Son of Y.
X & Y means X is the Wife of Y.
X $ Y means X is the Mother of Y.
Which of the following shows the relationship A is the maternal uncle of J?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A @ K $ T & G % J
Each symbol stands for one relation, read as “the left letter is the ... of the right letter”. A maternal uncle is the brother of one’s mother, so the chain must make A a male child of the same parent as J’s mother.
% : father of
@ : son of
& : wife of
$ : mother of
Option (2), pair by pair:
A @ K: A is the son of K, so A is male
K $ T: K is the mother of T, so A and T are children of K: A is T’s brother
T & G: T is the wife of G, so T is a woman
G % J: G is the father of J, so his wife T is J’s mother
A is the brother of J’s mother, so A is the maternal uncle of J. The first pair, A @ K, fixes A as male.
Why the other options are incorrect
Option (1) A @ K $ T & J — Incorrect. A is T’s brother and T is J’s wife, so A is J’s brother-in-law.
Option (3) A & K $ T @ J — Incorrect. A & K makes A the wife of K, a woman, so A cannot be an uncle.
Option (4) A @ K % T & G $ J — Incorrect. T & G makes G the husband of T, but G $ J calls G the mother of J; the chain contradicts itself.
