Solving the Blood Relation Puzzle

This question asks us to determine the relationship between a woman in a picture and Raju based on a statement made by Raju. Let's break down the statement carefully to figure out the connection.

Analyzing Raju's Statement

Raju says, "Her mother-in-law has only one grandchild whose mother is my wife."

Let's dissect the statement step by step:

• "my wife": This refers to Raju's wife.
• "whose mother is my wife": This part describes the grandchild. The mother of the grandchild is Raju's wife. This means the grandchild is the child of Raju and Raju's wife. So, Raju's child is the grandchild being referred to.
• "has only one grandchild whose mother is my wife": This tells us that the person mentioned at the beginning of the statement has only one grandchild, and that grandchild is Raju's child.
• "Her mother-in-law": This refers to the mother-in-law of the woman in the picture. So, the mother of the woman in the picture's husband is her mother-in-law.

Connecting the Relationships

Putting it together: The mother-in-law of the woman in the picture has only one grandchild, and that grandchild is Raju's child.

So, the woman in the picture's mother-in-law is the grandmother of Raju's child. There are two main ways someone can be a grandmother of Raju's child:

1. Raju's mother.
2. Raju's wife's mother.

The statement says the woman in the picture's mother-in-law is the person who has the grandchild. If the woman in the picture's mother-in-law is Raju's mother, then Raju's mother is the grandmother of Raju's child (which is true).

Identifying the Woman in the Picture

We know that the woman in the picture's mother-in-law is Raju's mother.

Who is Raju's mother's daughter-in-law? Raju's wife is his mother's daughter-in-law. The person whose mother-in-law is Raju's mother must be Raju's wife.

Let's verify this:

• If the woman in the picture is Raju's wife:
  • Her mother-in-law is Raju's mother.
  • Raju's mother has only one grandchild (Raju's child).
  • The mother of that grandchild is Raju's wife.

This sequence perfectly matches the statement made by Raju.

Let's consider other options briefly:

• If the woman is Raju's sister: Her mother-in-law is her husband's mother. For this person to have Raju's child as her only grandchild, Raju's child would have to be the child of Raju's sister's husband's mother's son/daughter. This doesn't fit the relation directly.
• If the woman is Raju's mother: Her mother-in-law is Raju's father's mother (Raju's paternal grandmother). Raju's child is the grandchild of Raju's mother, not necessarily Raju's paternal grandmother (unless Raju's father is an only child). More importantly, the mother of the grandchild (Raju's wife) would be the woman in the picture's daughter-in-law, not fitting the initial part of the statement "Her mother-in-law...".
• If the woman is Raju's aunt: Her mother-in-law is her husband's mother. Similar to the sister case, it's a complex path that doesn't directly align with Raju's statement as clearly as the wife relation.

Therefore, the woman in the picture must be Raju's wife.

Conclusion on the Relationship

Based on the analysis of Raju's statement, the woman in the picture is Raju's wife.

Additional Information - Solving Blood Relation Questions

Blood relation questions are common in logical reasoning tests. They require you to deduce relationships between people based on given information. Here are some tips for solving them:

• Draw a family tree: This is often the easiest way to visualize the relationships. Use symbols for male, female, marriage, and siblings.
• Break down the statement: Analyze the statement segment by segment, starting from the end (e.g., "my wife") and working backward or forward.
• Identify the speaker: Understand who is making the statement (in this case, Raju).
• Consider all possibilities: Sometimes, there might be multiple interpretations, but usually one fits all conditions perfectly.
• Substitute names: Once you deduce a relationship, substitute the person's name into the statement to see if it makes sense.

Practicing different types of blood relation puzzles helps improve your logical reasoning skills.
