Read the following information carefully and answer the given questions.

'A + B' means A is sister of B.
'A - B' means A is husband of B.
'A × B' means A is brother of B.
'A ÷ B' means A is daughter of B.

How is P related to M in the expression M ÷ L - N + P × Q ?

  • A.Father
  • B.Maternal uncle
  • C.Son
  • D.Grandfather

Answer: B

P is M's maternal uncle.

Read the expression M ÷ L - N + P × Q step by step:

  • M ÷ L: M is the daughter of L.
  • L - N: L is the husband of N, so N is M's mother.
  • N + P: N is the sister of P.
  • P × Q: P is the brother of Q, so P is male.

P is the brother of M's mother, that is, M's maternal uncle. He cannot be her father (that is L), her son, or her grandfather.
