SSC CGL 2019 (Tier 2) GS Finance & Economics Previous Year Paper (17-Nov-2020)
The correct answer is

Maternal Grandfather

This question asks us to determine the relationship between two people, Kavinder and Satish, based on a series of given relationships between several individuals. To solve this type of blood relation puzzle, we need to break down each statement and build a family structure step by step.

Analyzing the Blood Relation Statements

Let's analyze each statement provided in the question:

  • Statement 1: Amit is the brother of Sonia.

    This means Amit and Sonia are siblings and are in the same generation.

  • Statement 2: Jyoti is the sister of Nikita.

    Jyoti and Nikita are siblings and are in the same generation.

  • Statement 3: Sonia is the daughter of Satish’s father.

    This statement implies that Sonia and Satish share the same father. Therefore, Sonia is the sister of Satish. This also means Amit, Sonia, and Satish are siblings (from Statement 1 and 3).

  • Statement 4: Nikita is the daughter of Kavinder.

    Kavinder is the parent (father or mother) of Nikita.

  • Statement 5: Jyoti is the mother of Amit.

    Since Amit, Sonia, and Satish are siblings (from deductions based on Statements 1 and 3), Jyoti being Amit's mother means she is also the mother of Sonia and Satish.

  • Statement 6: Mukesh is Nikita’s only sister’s husband.

    From Statement 2, Jyoti is Nikita's sister. The statement says Nikita's *only* sister. This confirms Jyoti is Nikita's only sister. Mukesh is Jyoti's husband.

  • Statement 7: Kavinder is male.

    This tells us Kavinder is a man.

Building the Family Structure

Now, let's connect the relationships we've identified:

  1. From Statements 1, 3, and 5: Jyoti is the mother of Amit, Sonia, and Satish. They are siblings. Their father is Satish's father.
  2. From Statements 2 and 4: Nikita is the daughter of Kavinder, and Jyoti is the sister of Nikita. This means Kavinder is the parent of both Nikita and Jyoti (as siblings).
  3. From Statement 7: Kavinder is male. Combined with point 2, Kavinder is the father of Nikita and Jyoti.
  4. From point 1, Jyoti is the mother of Satish. From point 3, Kavinder is the father of Jyoti.

So, we have established that Jyoti is Satish's mother, and Kavinder is Jyoti's father.

Determining Kavinder's Relationship to Satish

Kavinder is the father of Satish's mother (Jyoti). The father of one's mother is known as the maternal grandfather.

Therefore, Kavinder is the maternal grandfather of Satish.

Let's summarize the key connections leading to the answer:

  • Amit, Sonia, and Satish are siblings.
  • Jyoti is their mother.
  • Jyoti and Nikita are sisters.
  • Kavinder is the father of Nikita and Jyoti.
  • Kavinder is male.
  • So, Kavinder is the father of Jyoti, who is the mother of Satish.
  • This makes Kavinder the maternal grandfather of Satish.

Final Relationship

Based on the analysis and the family structure derived, Kavinder is Satish's mother's father, which means Kavinder is the Maternal Grandfather of Satish.

Additional Information: Solving Blood Relation Problems

Blood relation questions test your ability to decipher and connect different relationships. Here are some tips for solving them effectively:

  • Read the entire question carefully to get an overview of the people involved.
  • Break down the problem into smaller statements.
  • Try to visualize or draw a family tree diagram. Use symbols (like squares for males, circles for females, double lines for marriage, single lines for siblings, vertical lines for parent-child) to represent relationships visually.
  • Start with a definite relationship and build upon it. For example, a direct parent-child or husband-wife relationship.
  • Connect different pieces of information. Look for individuals mentioned in multiple statements.
  • Pay attention to keywords like "only" (e.g., "only son," "only sister"), which can restrict possibilities.
  • Be careful with gender. Some names might not clearly indicate gender, so rely only on the information given (like "Kavinder is male").
  • Work backward or forward from the individuals whose relationship is being asked.
  • Once you have a potential relationship, trace it back through the statements to ensure it is consistent with all the given information.

Practicing with different types of blood relation puzzles will help improve your speed and accuracy in competitive exams.
