Question

Consider the following information and answer the given question

M is the mother of N.

N is the brother of O.

O is the wife of P.

P is the son of Q.

How is O related to Q?

1. A. Grand Daughter
2. B. Mother
3. C. Daughter
4. D. Daughter-in-law (Correct answer)

Correct Answer

Option D — Daughter-in-law

Detailed Solution & Explanation

The correct answer is Daughter-in-law.

Key Points

• Working through each statement:
  • M is the mother of N → N is M's child.
  • N is the brother of O → O is N's sibling, so O is also M's child.
  • O is the wife of P → O is female, and P is her husband.
  • P is the son of Q → Q is P's parent.
• Since O is married to P, and P is the son of Q, O is the wife of Q's son — that is, Q's daughter-in-law.

Shortcut Trick

• Work backwards from the two people named in the question. Here only the chain O → P → Q matters, and the first two statements about M and N are entirely redundant. Identifying the shortest path between the two people in question avoids drawing the whole family tree.

Additional Information

• Note the gender clue. "O is the wife of P" is what establishes O as female — without it, the answer could not be "daughter-in-law". Watch for gender being fixed by relationship words: *wife, mother, sister, daughter, aunt* are female; *husband, father, brother, son, uncle* are male. Words like *cousin, spouse, sibling, child* and *in-law* leave gender open.
• Standard notation for solving these questions:
  • Use + for male and − for female.
  • Draw a horizontal line for same-generation links (siblings, spouses) and a vertical line for parent-to-child links.
• Distractor check: "Granddaughter" would require O to be the child of Q's child; "Daughter" would require O to be Q's own child. Both confuse a marital link with a blood link, which is the standard trap in this question type.
