Understanding Blood Relations: Analyzing Family Connections

This question involves a classic blood relation puzzle. We need to determine the relationship between the lady and the man based on the statement made by the man.

Let's break down the statement step by step:

• The man says, "your mother's husband's sister is my Aunt".
• First, consider "your mother's husband". For the lady, her mother's husband is her father.
• So the phrase becomes, "your father's sister is my Aunt".
• The lady's father's sister is the lady's paternal aunt.
• The man states that the lady's paternal aunt "is my Aunt".

This means the person who is the lady's aunt is also the man's aunt. If they share the same aunt, it implies they are from the same family line where that aunt belongs. The aunt is the sister of their father.

Therefore, the lady and the man share the same father (whose sister is the aunt). People who share the same father are siblings.

Based on this analysis, the lady is the man's sister.
