Question

Which of the following statements is true?

• A. B and D are brothers
• B. A is D's daughter
• C. If E is B's daughter, then she is A's sister
• D. If F is C's grand-daughter, then she is A's sister
• A. D is A's aunt
• B. D is A's uncle
• C. A is D's niece
• D. A is D's father's son's grand daughter

Answer 1

The Correct Option is C

This is a logic puzzle about family relationships. You are given information about how A, B, C, and D are related:

• A is the daughter of B.
• B is the son of C.
• C is the father of D.

You are then asked to determine which of the following statements is true:

• A: B and D are brothers.
• B: A is D's daughter.
• C: If E is B's daughter, then she is A's sister.
• D: If F is C's granddaughter, then she is A's sister.

By constructing a family tree and analyzing the possible connections, we find that the only true statement is C: If E is another daughter of B, she would be A's sister.
The correct answer is (C) : If E is B's daughter, then she is A's sister

Answer 2

This logic puzzle asks you to identify the false statement among several options describing the relationship between A and D, who are related through a family tree.

Key information:

• A is the daughter of B.
• B is the son of C.
• C is the father of D.

By constructing a family tree and carefully analyzing each statement, we can deduce that the only necessarily false statement is:

D (A is D's father's son's grand-daughter): This statement creates a paradox where A would be the granddaughter of her own potential daughter, which is impossible.
The correct answer is (D) : A is D's father's son's grand daughter
