Understanding Blood Relation Coding

This question involves decoding a set of relationships represented by symbols and then using the decoded information to determine the relationship between two specific individuals in a given expression. Let's first understand the meaning of each symbol:

• \(A + B\) means \(A\) is the sister of \(B\).
• \(A - B\) means \(A\) is the daughter of \(B\).
• \(A \times B\) means \(A\) is the brother of \(B\).
• \(A \div B\) means \(A\) is the husband of \(B\). (Note: The expression uses symbols +, -, and ×, but the definition for ÷ is provided, though not used. We will focus on the symbols used in the expression).

Decoding the Blood Relation Expression

The given expression is \(V + U \times Q - T + R + P \times S\). We need to break this down segment by segment from left to right to build the family tree.

1. \(V + U\): According to the code, \(V + U\) means \(V\) is the sister of \(U\).
2. \(U \times Q\): According to the code, \(U \times Q\) means \(U\) is the brother of \(Q\).

   From steps 1 and 2, we know that \(V\) is the sister of \(U\), and \(U\) is the brother of \(Q\). This means \(V\), \(U\), and \(Q\) are siblings. \(V\) is female (sister) and \(U\) is male (brother). \(Q\)'s gender is not yet determined from this part alone.

3. \(Q - T\): According to the code, \(Q - T\) means \(Q\) is the daughter of \(T\).

   This tells us that \(T\) is the parent of \(Q\). Since \(V\), \(U\), and \(Q\) are siblings, \(T\) is the parent of \(V\), \(U\), and \(Q\).

4. \(T + R\): According to the code, \(T + R\) means \(T\) is the sister of \(R\).

   This confirms \(T\) is female.

5. \(R + P\): According to the code, \(R + P\) means \(R\) is the sister of \(P\).

   From steps 4 and 5, \(T\) is the sister of \(R\), and \(R\) is the sister of \(P\). This means \(T\), \(R\), and \(P\) are siblings. \(T\) is female (sister) and \(R\) is female (sister). \(P\)'s gender is not yet determined from this part alone.

6. \(P \times S\): According to the code, \(P \times S\) means \(P\) is the brother of \(S\).

   This confirms \(P\) is male. From steps 4, 5, and 6, \(T\), \(R\), \(P\), and \(S\) are siblings. \(T\) is female, \(R\) is female, and \(P\) is male. \(S\)'s gender is not determined.

Constructing the Family Relationship Diagram

Based on the decoded relationships, we can summarize the connections:

• \(V\), \(U\), \(Q\) are siblings. \(V\) is female, \(U\) is male, \(Q\) is female (daughter of T).
• \(T\) is the parent of \(V\), \(U\), and \(Q\).
• \(T\), \(R\), \(P\), \(S\) are siblings. \(T\) is female, \(R\) is female, \(P\) is male.

Since \(T\) is female and is the parent of \(V\), \(T\) is \(V\)'s mother. \(P\) is the brother of \(T\). Therefore, \(P\) is the brother of \(V\)'s mother.

Determining the Relationship of P to V

We have established that:

• \(T\) is the mother of \(V\).
• \(P\) is the brother of \(T\).

The brother of one's mother is one's maternal uncle.

Thus, \(P\) is the maternal uncle of \(V\).

Analyzing the Options

Let's check the given options:

• Paternal aunt: Incorrect, P is male and related through the mother's side.
• Paternal uncle: Incorrect, related through the mother's side.
• Maternal uncle: Correct, P is male and is the brother of V's mother.
• Maternal aunt: Incorrect, P is male.

The relationship of \(P\) to \(V\) is that \(P\) is the Maternal uncle of \(V\).

Combining the deductions:

• V, U, Q are siblings, and T is their parent.
• T, R, P, S are siblings.
• T is female. Since T is V's parent and is female, T is V's mother.
• P is the brother of T.
• Therefore, P is the brother of V's mother, making P the maternal uncle of V.

Additional Information: Tips for Solving Blood Relation Puzzles

Solving blood relation puzzles often involves systematically breaking down the given information. Here are some helpful tips:

• Draw a Family Tree: Visualizing the relationships using a diagram can make it much easier to track connections and genders.
• Determine Gender: Pay close attention to which parts of the relation definition assign a gender (e.g., "A is the sister of B" tells you A's gender, but not B's).
• Break Down Complex Expressions: Handle expressions segment by segment, working from left to right.
• Identify Generations: Place individuals on different levels in your tree to represent parent-child or grandparent-grandchild relationships.
• Practice Different Types: Familiarize yourself with coded relations, puzzles based on conversations, and family tree-based questions.
