Father’s father
Solving the Blood Relation Puzzle
This question involves a blood relation puzzle. We need to carefully trace the relationships described in the statement to determine how B is related to F. Let's break down the statement step by step, starting from the end.
The statement is: “She (A) is my sister G’s father D’s sister E’s father B’s wife”.
- "My sister G": This refers to F's sister, who is G. (F and G are siblings).
- "sister G’s father D": This means D is the father of G. Since G is F's sister, D is also F's father. (F and G are children of D).
- "father D’s sister E": This means E is the sister of D. (D and E are siblings, children of B).
- "sister E’s father B": This means B is the father of E.
- "father B’s wife": This means A is the wife of B.
Let's consolidate the relationships we have found:
- F and G are siblings.
- D is the father of F and G.
- E is the sister of D.
- B is the father of E.
- A is the wife of B.
We want to find the relationship between B and F.
We know that D is F's father (\(F \leftarrow D\)).
We also know that E is D's sister (\(D \leftrightarrow E\)).
And we know that B is E's father (\(E \leftarrow B\)).
If B is E's father, and E is D's sister, then B must also be D's father.
So, B is the father of D (\(D \leftarrow B\)).
Since D is F's father, and B is D's father, B is F's father's father.
In simpler terms:
- F's father is D.
- D's father is B.
- Therefore, B is F's grandfather (father's father).
The relationship of A (B's wife) was used to identify A, but it is not needed to find the relationship between B and F.
Thus, B is F's father's father.
Blood Relation Analysis Table
| Step | Relationship from Statement | Deduction |
|---|---|---|
| 1 | My sister G | G is F's sister (\(F \leftrightarrow G\)) |
| 2 | sister G’s father D | D is G's father. D is also F's father (\(F \leftarrow D, G \leftarrow D\)) |
| 3 | father D’s sister E | E is D's sister (\(D \leftrightarrow E\)) |
| 4 | sister E’s father B | B is E's father (\(E \leftarrow B\)) |
| 5 | father B’s wife (is A) | A is B's wife (\(A \leftrightarrow B\)) |
Combining deductions 2, 3, and 4:
- D is F's father.
- E is D's sister.
- B is E's father.
If B is E's father and E is D's sister, then B is also D's father. Since D is F's father, B is F's father's father.

Additional Information on Blood Relations
Blood relation questions test your ability to understand and interpret complex chains of relationships. It is helpful to use diagrams or symbols to represent relationships and trace them clearly. Common symbols used include:
- Horizontal line (\(\leftrightarrow\)) for siblings or spouses.
- Vertical line (\(\downarrow\) or \(\uparrow\)) to indicate parent-child relationship (e.g., \(Child \leftarrow Parent\)).
- Boxes or circles to denote gender (optional, but can be helpful).
When solving these puzzles, always break down the statement into smaller, manageable parts and build the family tree or relationship chain step by step from the end of the statement back to the person in question. Be careful with possessives (e.g., 'D's sister' means the sister belongs to D, or is related through D) and identify the 'my' person correctly (in this case, F).
