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
Reading the symbols in turn: A @ K makes A the son of K, K $ T makes K the mother of T, so A and T are brother and sister. Then T & G makes T the wife of G and G % J makes G the father of J, so T is J’s mother.
A is therefore the brother of J’s mother, that is J’s maternal uncle. In the other chains A is either female or is linked to J through the father’s side.
