Understanding the Blood Relation Puzzle

The question asks us to determine how Sarika is related to a boy, based on a statement Sarika makes about him. Let's break down Sarika's statement step by step to figure out the relationship.

Sarika says, "He is my sister's son's father's wife's only sister's son."

Step-by-Step Blood Relation Analysis

Let's analyze the statement from Sarika's perspective:

1. "My sister's son": This person is Sarika's nephew. Let's call him Nephew N.
2. "My sister's son's father": The father of Nephew N. is the husband of Sarika's sister. This person is Sarika's brother-in-law. Let's call him Brother-in-law BIL.
3. "My sister's son's father's wife": The wife of Brother-in-law BIL is Sarika's sister. This is the same sister mentioned at the beginning. Let's call her Sister S.
4. "My sister's son's father's wife's only sister": Sister S has an "only sister". If Sarika's sister has only one sister, that person must be Sarika herself. This part of the statement refers to Sarika.
5. "My sister's son's father's wife's only sister's son": This is the son of Sarika (the "only sister" from the previous step).

Therefore, the statement "He is my sister's son's father's wife's only sister's son" simplifies to "He is Sarika's son".

Determining Sarika's Relationship to the Boy

Based on our analysis, the boy is Sarika's son. The question asks how Sarika is related to the boy. If the boy is her son, then Sarika is his mother.

Evaluating the Options

Let's look at the given options:

• Maternal grandmother: This would mean Sarika is the mother of the boy's mother or father, which is not the case.
• Maternal aunt: This would mean Sarika is the sister of the boy's mother, which is not the case.
• Sister: This would mean Sarika is the boy's sister, which is not the case.
• Mother: This means Sarika is the boy's mother, which matches our conclusion.

The correct relationship is that Sarika is the boy's mother.

Summary of the Relationship

Let's visualize the relationship chain:

Boy $\leftarrow$ Son of (Only Sister of (Wife of (Father of (Son of (Sarika's Sister)))))

Simplifying:

• Sarika's Sister's Son = Sarika's Nephew
• Sarika's Sister's Son's Father = Sarika's Sister's Husband = Sarika's Brother-in-law
• Sarika's Sister's Son's Father's Wife = Sarika's Sister
• Sarika's Sister's Son's Father's Wife's Only Sister = Sarika
• Sarika's Sister's Son's Father's Wife's Only Sister's Son = Sarika's Son

So, the boy is Sarika's son.

Therefore, Sarika is the boy's mother.

Additional Information on Solving Blood Relation Questions

Blood relation questions require careful step-by-step decoding of the given statement. Here are some tips:

• Start decoding from the end of the statement and move towards the beginning, or start from the perspective of the person making the statement.
• Break down complex sentences into smaller, manageable parts.
• Use diagrams or family trees if helpful, but often step-by-step text analysis is sufficient for simpler relations.
• Pay close attention to words like "only," which significantly restrict possibilities.
• Clearly identify the two individuals whose relationship is being asked.

Practicing different types of blood relation questions helps improve speed and accuracy.
