Understanding the Blood Relation Puzzle

This question involves a classic blood relation puzzle. We need to carefully break down the statement made by Neeraj to determine his relationship with the lady in the photo.

Analyzing Neeraj's Statement

Neeraj says, "She is the daughter of my paternal grandfather's only son." Let's analyze this statement part by part from Neeraj's perspective:

• "My paternal grandfather": This refers to Neeraj's father's father.
• "My paternal grandfather's only son": Neeraj's paternal grandfather has only one son. Since Neeraj is the grandson of his paternal grandfather, that only son must be Neeraj's father.

So, the phrase "my paternal grandfather's only son" simplifies to "my father".

Connecting the Statement to the Lady

Now, substitute this back into the original statement:

• "She is the daughter of my paternal grandfather's only son" becomes "She is the daughter of my father."

The daughter of one's father is one's sister.

Therefore, the lady in the photo is Neeraj's sister.

Determining Neeraj's Relation with the Lady

The question asks for the relation of Neeraj with the lady in the photo. Since the lady is Neeraj's sister, Neeraj is her brother.

Evaluating the Options

Let's look at the given options:

1. Father: This is incorrect. Neeraj is not the lady's father.
2. Father-in-law: This is incorrect. This relationship involves marriage.
3. Uncle: This is incorrect. An uncle is a father's or mother's brother.
4. Brother: This is correct. If the lady is Neeraj's sister, then Neeraj is her brother.

Based on the analysis, the relation of Neeraj with the lady in the photo is Brother.

Additional Information on Blood Relations

Solving blood relation questions often involves tracing the relationships backwards or drawing a family tree diagram. Here are some tips:

• Break down complex statements into smaller, manageable parts.
• Start from the "my" part of the statement (e.g., "my paternal grandfather").
• Use symbols or diagrams to represent family members and their relationships if the puzzle is complex.
• Common terms like 'paternal' (father's side) and 'maternal' (mother's side) are important.
• 'Only son' or 'only daughter' clauses are crucial as they limit possibilities.
