Understanding the Blood Relation Puzzle
This question asks us to figure out the relationship between Nitin and Sanchi's mother based on a statement Nitin made while pointing to Sanchi's photograph. Let's break down the statement step by step to understand the complex chain of relations described.
Step-by-Step Analysis of Nitin's Statement
Nitin says, “Her mother’s father’s son’s wife is my mother-in-law’s only daughter”.
Let's analyse the first part of the statement, which refers to a person related to Sanchi:
- "Her" refers to Sanchi.
- "Her mother" refers to Sanchi's mother.
- "Her mother's father" refers to Sanchi's maternal grandfather. This is the father of Sanchi's mother.
- "Her mother's father's son" refers to the son of Sanchi's maternal grandfather. This son could be Sanchi's mother's brother or Sanchi's mother herself (if she had no brothers). However, in blood relation puzzles, "son" typically refers to a male descendant. Since the statement continues, this "son" is distinct from Sanchi's mother. So, "Her mother's father's son" is Sanchi's maternal uncle (brother of Sanchi's mother).
- "Her mother's father's son's wife" refers to the wife of Sanchi's maternal uncle. This person is Sanchi's aunt (specifically, her maternal uncle's wife) and the sister-in-law of Sanchi's mother.
Now let's analyse the second part of the statement, which refers to a person related to Nitin:
- "My" refers to Nitin.
- "My mother-in-law" refers to the mother of Nitin's wife.
- "My mother-in-law's only daughter" refers to the only daughter of Nitin's mother-in-law. Since Nitin's mother-in-law is the mother of Nitin's wife, her only daughter must be Nitin's wife.
Connecting the Two Parts
The statement says that the person from Sanchi's side ("Her mother's father's son's wife") is the same person as the one from Nitin's side ("my mother-in-law's only daughter").
So, we have:
The wife of Sanchi's maternal uncle = Nitin's wife
If the wife of Sanchi's maternal uncle is Nitin's wife, it means Nitin is married to Sanchi's maternal uncle's wife. For this to be true, Nitin must be Sanchi's maternal uncle.
Let's verify this:
- If Nitin is Sanchi's maternal uncle, then Nitin is the brother of Sanchi's mother.
- Nitin's wife would be the wife of Sanchi's maternal uncle.
- Is Nitin's wife also Nitin's mother-in-law's only daughter? Yes, because Nitin's wife is the daughter of Nitin's mother-in-law. The statement says "only daughter", which confirms that Nitin's wife is indeed the person being referred to.
So, the conclusion holds: Nitin is Sanchi's maternal uncle, which means Nitin is the brother of Sanchi's mother.
Determining the Final Relationship
The question asks: "How is Nitin related to Sanchi’s mother?"
Based on our analysis, Nitin is the brother of Sanchi's mother.
