Analyzing Family Relationships for Logical Reasoning

This question requires us to deduce the relationship between two individuals, Kartik and Ankit, based on a series of given family relationships. We need to carefully break down each statement and connect the individuals involved.

Step-by-Step Relationship Analysis

Let's analyze each statement to build the family tree step by step:

  • Statement 1: "Saloni is the daughter of the only son of Kartik."
    This tells us that Kartik has only one son. Let's call this son 'S'. Saloni is the daughter of S. So, S is Saloni's father, and Kartik is Saloni's paternal grandfather.
  • Statement 2: "Nirupama is the mother of Deepak."
    This establishes Nirupama and Deepak as mother and son.
  • Statement 3: "Yamini’s only son, Ankit, is married to Nirupama."
    Yamini has only one son, Ankit. Ankit is married to Nirupama. Since Nirupama is Deepak's mother (from statement 2) and Ankit is her husband, Ankit must be Deepak's father.
  • Statement 4: "Kartik is the paternal grandfather of Deepak."
    A paternal grandfather is the father of one's father. We know Ankit is Deepak's father (from statement 3). Therefore, Kartik must be the father of Ankit.

Connecting the Relationships

From Statement 1, we know Kartik has an only son (S). From Statement 4, we determined that Kartik is the father of Ankit. This means Ankit is Kartik's son. Since Kartik has only one son, Ankit must be that 'only son' mentioned in Statement 1.

Summary of Key Relationships

Based on the analysis, we can establish the following direct relationships:

  • Kartik is the father of Ankit.
  • Ankit is the only son of Kartik.
  • Ankit is married to Nirupama.
  • Ankit and Nirupama are the parents of Deepak.
  • Kartik is the paternal grandfather of Deepak (father of Deepak's father, Ankit).
  • Ankit is the father of Saloni (since he is Kartik's only son, and Saloni is the daughter of Kartik's only son).

The question asks for the relationship between Kartik and Ankit.

Our analysis clearly shows that Kartik is the father of Ankit.

Conclusion on Kartik and Ankit Relationship

The relationship between Kartik and Ankit is that Kartik is Ankit's father. Ankit is Kartik's only son.

Therefore, Kartik is the Father of Ankit.

Additional Information: Solving Family Relation Puzzles

Family relationship questions are common in logical reasoning sections. To solve them effectively:

  • Draw a diagram: A visual representation like a family tree can help keep track of complex relationships.
  • Break down statements: Analyze each piece of information separately before combining them.
  • Identify keywords: Terms like "only son," "paternal grandfather," etc., are crucial.
  • Establish direct links: Find the direct relationship between individuals first.
  • Connect indirect links: Use established relationships to find indirect ones (e.g., if A is father of B, and B is father of C, then A is grandfather of C).
  • Work forwards and backwards: Sometimes starting from the person whose relationship you need to find, and other times starting from the known points, can be helpful.

In this specific problem, identifying Ankit as Deepak's father and Kartik as Deepak's paternal grandfather directly leads to Kartik being Ankit's father. The "only son" detail confirms Ankit's position in Kartik's lineage.
