Solving Blood Relation Puzzles

Let's break down the statement given by Priya to understand the relationship between the man she pointed at and herself. The statement is: "he is her brother's paternal grandmother's only child."

We need to trace the relationship step-by-step, starting from Priya's brother:

  1. Priya's brother: This is a direct relative.
  2. Priya's brother's paternal grandmother: The paternal grandmother of Priya's brother is the mother of his father. Since Priya and the brother share the same father, this paternal grandmother is also Priya's paternal grandmother.
  3. Priya's brother's paternal grandmother's only child: This refers to the only child of Priya's paternal grandmother. The children of a paternal grandmother are her son(s) and daughter(s). Since she is the *paternal* grandmother, her son is the father of Priya's brother (and Priya). The statement specifies her *only* child. This means this son is the only child she has. Therefore, the only child of Priya's paternal grandmother is Priya's father.

So, the man Priya pointed towards is her father.

Relationship Analysis in Detail

Let's visualize the family structure based on the statement:

  • Priya has a brother.
  • They share a paternal grandmother. This grandmother is the mother of their father.
  • The grandmother has only one child. This child is the father of Priya's brother and Priya.
  • The man is this only child.

Therefore, the man is Priya's father.

Evaluating the Options

Let's look at the given options in the context of our conclusion:

  • Brother: The man is Priya's father, not her brother.
  • Paternal grandfather: The man is the only child of the paternal grandmother, which makes him Priya's father, not her paternal grandfather (who is the paternal grandmother's husband).
  • Father: Our analysis shows the man is Priya's father. This option matches.
  • Son: The man is Priya's father, not her son.

Based on the detailed relationship analysis, the correct relationship is Father.

Relationship Step Interpretation
Priya's brother Starting point relative
Brother's paternal grandmother Priya's paternal grandmother (mother of her father)
Grandmother's only child The only child of Priya's paternal grandmother. This must be Priya's father as she is the paternal grandmother.

Additional Information on Solving Blood Relation Questions

Blood relation questions test your ability to understand and trace relationships within a family tree. Here are some tips for solving them:

  • Break down the statement into smaller parts.
  • Start tracing the relationship from the end of the statement backwards towards the person pointing or being pointed at.
  • Draw a family tree diagram if the relationships are complex.
  • Identify the gender of individuals where specified (e.g., brother, grandmother, child).
  • Be careful with terms like 'only child', 'only son', 'only daughter', as they limit possibilities.
