Question 58
In a certain code language,
A = B means ‘A is the sister of B’,
A ÷ B means ‘ A is the father of B’,
A £ B means ‘A is the brother of B’, and
A + B means ‘A is the wife of B’.
Which of the following means that F is the Mother's brother of Z?
Solution
In the expression F £ G = H + Y ÷ Z, we work backward: Y ÷ Z and H + Y establish that H is the mother of Z. The symbols G = H and F £ G show that G and F are siblings of H. Specifically, F £ G identifies F as a male (brother). Since F is the brother of Z's mother (H), F is the maternal uncle of Z. This satisfies the condition that F is the mother's brother of Z.
