Show answer & explanation
Correct answer: B
Concept
In a coded-relationship expression, replace each symbol with the relationship it stands for and read the chain one link at a time between adjacent people. Track each person's gender from the relationship words, then trace the path from the first named person to the second.
Applying it to M ÷ L − N + P × Q
M ÷ L means M is the daughter of L, so L is a parent of M.
L − N means L is the husband of N; therefore L is male (M's father) and N is female (M's mother).
N + P means N is the sister of P, so P is a sibling of N — and N is M's mother.
P × Q means P is the brother of Q, which confirms that P is male.
Cross-check
P is male and is the brother of N, who is M's mother. The brother of one's mother is the maternal uncle. Hence P is the maternal uncle of M.
