Solving Blood Relation Puzzles
This blood relation question asks us to determine the relationship between two individuals, D and F, based on a series of defined relationships within a family. To solve such blood relation puzzles, it's often helpful to build a family tree or diagram based on the given information. Let's break down the statements provided in the blood relation puzzle:
- Statement 1: F is C’s son. This tells us that C is the parent of F, and F is male.
- Statement 2: C is the only daughter of B. This means B is C's parent, and C is female. Since she is the 'only' daughter, B might have sons, but only one daughter.
- Statement 3: D is A’s only son-in-law. A son-in-law is the husband of a daughter. This tells us A has a daughter, and D is her husband. He is A's only son-in-law.
- Statement 4: B is C’s father. This confirms the relationship from Statement 2 and specifies B's gender as male.
- Statement 5: A is B's wife. This tells us A and B are a married couple.
Building the Family Connections
Let's combine these statements to understand the family structure in this blood relation puzzle:
- From Statement 4 and 5, we know B is C's father and A is B's wife. This means A is C's mother. So, A and B are the parents of C.
- From Statement 2, C is the only daughter of B (and therefore A).
- From Statement 3, D is A’s only son-in-law. Since C is A's only daughter, D must be the husband of C. This establishes the relationship between C and D.
- From Statement 1, F is C’s son.
Let's summarize the family structure we have built from the blood relation statements:
- A and B are a married couple.
- A and B are the parents of C (their only daughter).
- C is married to D.
- C and D are the parents of F.
Determining the Relationship between D and F
The question asks: How is D related to F?
From our family structure analysis: C is F's mother (Statement 1). D is C's husband (deduced from Statements 2, 3, 4, and 5). In a family, the husband of one's mother is one's father.
Therefore, D is F's father.
| Individual | Relation(s) derived |
|---|---|
| A | B's wife, C's mother |
| B | C's father, A's husband |
| C | A's & B's only daughter, D's wife, F's mother |
| D | A's only son-in-law, C's husband, F's father |
| F | C's son |
Based on the analysis of the blood relation puzzle, D is the father of F.
