Solving the Blood Relation Puzzle: Lady's Relationship to Varun

This is a classic blood relation puzzle where we need to deduce the relationship between a lady and Varun based on a given statement.

Let's break down the statement given by Varun step-by-step:

• The statement is: “The son of her only brother is the brother of my wife”.

Analyzing the Statement Parts

We can analyze the statement from the end to make it clearer:

• “...the brother of my wife”: This person is Varun’s brother-in-law.
• “The son of her only brother...”: This person is the son of the lady’s only brother. This means he is the lady’s nephew.

Combining these two points:

• The lady’s nephew is Varun’s brother-in-law.

Connecting the Relationships

If the lady’s nephew is Varun’s brother-in-law (who is the brother of Varun’s wife), then the father of this nephew must be the father of Varun’s wife.

• The father of the lady’s nephew is the lady’s only brother.
• The father of Varun’s wife is Varun’s father-in-law.

Therefore, the lady’s only brother is Varun’s father-in-law.

Determining the Lady's Relationship to Varun

The lady is the sister of her only brother, who we have deduced is Varun’s father-in-law.

Thus, the lady is the sister of Varun’s father-in-law.

Let's summarize the relationship chain:

• Lady’s only brother $\rightarrow$ Varun’s father-in-law
• Lady is the sister of $\rightarrow$ Lady’s only brother
• Therefore, Lady is the sister of $\rightarrow$ Varun’s father-in-law

Based on this analysis, the lady is the sister of Varun’s father-in-law.
