HardOriginal questionIn a code, X + Y means X is the mother of Y; X − Y means X is the brother of Y; X × Y means X is the husband of Y; and X ÷ Y means X is the daughter of Y.

Show the answer and explanation
CorrectNot quiteAnswer D
Correct answer: D
Explanation
U × V: U is V's husband.
V ÷ W: V is W's daughter, so W is a parent of U's wife.
W is U's father-in-law if W is a man and U's mother-in-law if W is a woman.
No symbol ever states W's gender, so the relation cannot be determined.
Worth noting
Only the LEFT person of each symbol gets a gender. W appears only on the right, so W's gender is never fixed.
