The correct answer is

Father

Let's break down the given information step-by-step to understand the blood relations and determine how Q is related to V.

Analyzing the Blood Relation Statements

  • Statement 1: P is the sister of Q and mother of R.
    • This tells us P and Q are siblings.
    • P is female and has a child R.
  • Statement 2: S is the daughter-in-law of W and Wife of Q.
    • S is married to Q.
    • S is the daughter-in-law of W. For S to be W's daughter-in-law and Q's wife, Q must be W's son.
    • This confirms Q is male and married to S.
  • Statement 3: W’s grandson M is the nephew of P and brother of V.
    • M is W's grandson.
    • M is the nephew of P. A nephew of P (Q's sister) would typically be the son of P's sibling, which is Q. So, M is the son of Q.
    • M is the brother of V. This means V is also a child of Q (and S).
  • Statement 4: W has only two children.
    • We know Q is a child of W (from Statement 2).
    • We know P is a sibling of Q (from Statement 1).
    • Since W has only two children, P and Q must be W's only children. P is a daughter of W, and Q is a son of W.

Constructing the Family Structure

Based on the analysis, we can deduce the following family relationships:
  • W is in the eldest generation.
  • P and Q are children of W. P is female (sister of Q), Q is male (husband of S). W is their parent.
  • Q is married to S.
  • M and V are children of Q and S. M is male (grandson of W, nephew of P, brother of V), V is a sibling of M.
  • R is the child of P.
Let's visualize the structure:
Generation Individuals Relationships
1 (Eldest) W Parent of P & Q
2 P Child of W, Sister of Q, Mother of R
2 Q Child of W, Brother of P, Husband of S, Father of M & V
2 S Wife of Q, Daughter-in-law of W, Mother of M & V
3 R Child of P
3 M Son of Q & S, Grandson of W, Nephew of P, Brother of V
3 V Child of Q & S, Sibling of M, Grandchild of W

Determining Q's Relationship to V

The question asks, "How is Q related to V?". From our family structure, we see that V is a child of Q and S, and Q is the husband of S. Since Q is male, Q is the father of V. The relationship between Q and V is that Q is V's father.

Conclusion

By carefully analyzing each statement and combining the information, we have determined the family structure. Q is married to S, and they have children M and V. Therefore, Q is the father of V.

Additional Information - Solving Blood Relation Problems

Solving blood relation questions involves careful reading and building a visual representation like a family tree or using symbols. * Symbols: You can use symbols like '+' for male, '-' for female, '=' for marriage, '|' for parent-child, and '--' for siblings. * Generations: Group individuals by generations to avoid confusion. * Key Relationships: Understand common relations like nephew/niece (sibling's child), uncle/aunt (parent's sibling), cousin (uncle/aunt's child), etc. * Deduction: Use each piece of information to deduce relationships and build the tree gradually. Contradictions mean you might have misinterpreted a statement. * Question Focus: Always double-check who is related to whom in the final question (e.g., How is A related to B? vs. How is B related to A?).
