A is the father of B. B is the son of C, but C is not the mother of B. D is the brother of B. E is the sister of C. Who is the mother of D?
- A.ACorrect
- B.C
- C.E
- D.Data inadequate
Solution
A is the father of B, and B is the son of C, but C is not the mother of B. This means C is the father of B. D is the brother of B. Since A is the father of B and D, A is the father of both. Therefore, A is the father of D. The question asks 'Who is the mother of D?' Since A is the father, and C is also a male, A must be married to the mother of D. The question does not provide info on who the mother is. However, the question specifies that 'A is the father of B' so A is definitely the father of D, since D is the brother of B. The question asks *who is the mother of D*? It is incorrect to infer that the question is asking who the father is, so the correct answer must be 'Data inadequate'.
A is B's father. C is B's sister. D is C's mother. E is D's son. E is standing facing North and walks 5 km. He then turns right and walks 3 km. He then turns left and walks 2 km. What is the direction of A with respect to E's final position?
- A.South-WestCorrect
- B.North-East
- C.South-East
- D.North-West
Solution
A is the father of B, C is B's sister, D is C's mother so D is A's wife. E is D's son, so E is B's brother. E walks 5km North, 3km East, and 2km North. So, E is 7km North and 3km East of his starting point. Therefore, A is South-West of E's final location.

Blood Relations — Frequently Asked Questions
What is the standard method for blood relation questions?
Draw a family tree as you read — squares for males, circles for females, vertical lines for generations. Solving in your head fails exactly when the question is worth solving.
What is the most common trap in these questions?
Assuming gender. "Child of", "sibling of" and names do not reveal gender — if the final relationship depends on an unknown gender, the answer is "cannot be determined".
