SSC CGL 2018 (Tier 2) Statistics Previous Year Paper (22-feb-2018)
The correct answer is

Son-in-law

Let's break down the given information step by step to understand the family relationships and determine how V is related to P.

Analyzing the Blood Relation Puzzle

We are given several statements describing the relationships between members of a family: P, Q, R, S, T, and V. We need to find the relationship between V and P.

Here are the statements and what they tell us:

  • P is the father of Q: This means Q is a child of P. P is in the generation above Q.
  • P is the grandfather of R: This means R is a grandchild of P. R is two generations below P. Since P is the father of Q, R must be the child of Q or a child of Q's sibling.
  • R is the brother of S: R and S are siblings. They share the same parents.
  • S’s mother, T, is married to V: T is the mother of S (and since R is S's brother, T is also R's mother). T is married to V, which means V is the father of S (and R). T and V are the parents of R and S.
  • T is the sister of Q: T and Q are siblings. They share the same parent(s).

Building the Family Structure

Let's put these relationships together:

  1. P is the father of Q.
  2. T is the sister of Q. This means T is also a child of P. So, P is the father of both Q and T.
  3. T is the mother of R and S.
  4. V is married to T. Since T is the mother of R and S, and V is married to T, V must be the father of R and S.
  5. P is the grandfather of R. This fits, as P is the father of T, and T is the mother of R. R is the child of P's child (T), making P the grandfather of R.

Based on this structure, we can see that:

  • P is in the topmost generation mentioned as a parent/grandparent.
  • Q and T are in the next generation below P (children of P).
  • R and S are in the generation below Q and T (children of T).
  • V is married to T.

Let's represent this relationship structure:

Person Relationship Parents Siblings Children Spouse
P Father of Q & T, Grandfather of R & S - - Q, T -
Q Child of P, Sibling of T P T Maybe, but not mentioned Maybe, but not mentioned
T Child of P, Sibling of Q, Mother of R & S P Q R, S V
V Father of R & S, Spouse of T - - R, S T
R Grandchild of P, Child of T & V, Brother of S T, V S - -
S Grandchild of P, Child of T & V, Sister of R T, V R - -

Determining the Relationship of V to P

We have established that T is the daughter of P (since P is the father of Q, and T is the sister of Q). We also know that V is married to T. Therefore, V is the husband of P's daughter, T.

The relationship of a husband to his wife's father is that of a son-in-law.

Thus, V is the son-in-law of P.

Conclusion on V's Relationship to P

Based on the detailed analysis of the family relationships, V is married to T, and T is the daughter of P. This makes V the son-in-law of P.

Comparing this with the given options:

  • Son: Incorrect. V is not P's son; T is P's daughter.
  • Brother-in-law: Incorrect. V is related through P's daughter, not a sibling.
  • Nephew: Incorrect. V is not the son of P's sibling.
  • Son-in-law: Correct. V is the husband of P's daughter.

Additional Information: Solving Blood Relation Questions

Solving blood relation questions effectively often involves visualizing the relationships or drawing a family tree. Here are some tips:

  • Identify genders where specified (e.g., 'father' is male, 'mother' is female, 'brother' is male, 'sister' is female). Sometimes gender is not specified (e.g., 'child', 'sibling', 'grandchild').
  • Break down complex sentences into smaller relationship units.
  • Use symbols or notations to represent relationships (e.g., horizontal line for siblings, vertical line for parent-child, double line for marriage).
  • Start with the most definitive relationships and build outwards.
  • Trace the path between the two individuals whose relationship you need to find.
  • Be careful with terms like 'in-law' relationships (e.g., son-in-law is your daughter's husband, brother-in-law could be your sibling's husband or your spouse's brother/sister's husband).

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