Understanding Blood Relation Symbols and Solving the Puzzle

This blood relation question requires us to decode the given symbols and then trace the relationships within the provided expression to find the connection between two individuals, T and Q.

Decoding the Blood Relation Symbols

First, let's understand what each symbol represents:

Symbol Meaning
A @ B A is the husband of B (Implying B is the wife of A)
A & B A is the father of B (Implying B is the child of A)
A # B B is the son of A (Implying A is the parent of B, and B is male)

Analyzing the Given Expression: S @ T # P @ Q # R & V

Now, let's break down the expression piece by piece:

  • S @ T: According to the rule 'A @ B' means 'A is the husband of B', this means S is the husband of T. Therefore, T is the wife of S. Gender: S is male, T is female.
  • T # P: According to the rule 'A # B' means 'B is the son of A', this means P is the son of T. Since T is female, T is the mother of P. Gender: P is male.
  • P @ Q: According to the rule 'A @ B' means 'A is the husband of B', this means P is the husband of Q. Therefore, Q is the wife of P. Gender: P is male, Q is female.
  • Q # R: According to the rule 'A # B' means 'B is the son of A', this means R is the son of Q. Since Q is female, Q is the mother of R. Gender: R is male.
  • R & V: According to the rule 'A & B' means 'A is the father of B', this means R is the father of V. V is the child of R. Gender: R is male, V's gender is not specified.

Tracing the Relationship between T and Q

Let's connect the derived relationships to find how T is related to Q:

  1. We know that T is the mother of P.
  2. We also know that P is the husband of Q.
  3. So, T is the mother of Q's husband (P).

The mother of one's husband is called the Mother-in-law.

Therefore, T is the mother-in-law of Q.

Final Answer Determination

Based on our step-by-step analysis of the blood relations defined by the symbols in the expression S @ T # P @ Q # R & V, we found that T is the mother-in-law of Q. We should select the option that states 'Mother-in-law'.

Additional Information on Blood Relation Reasoning

Blood relation reasoning questions test your ability to understand and interpret relationships between members of a family based on given information. These problems often use symbols or coded language to represent relationships, requiring you to decode them first.

Tips for solving blood relation problems:

  • Carefully read and understand the meaning of each symbol or phrase defining a relationship.
  • Break down the given expression or sentence into smaller parts.
  • Draw a family tree or diagram to visually represent the relationships as you decode them. This helps in keeping track of genders and generations.
  • Start from a known relationship and extend it step-by-step using the rules provided.
  • Determine the gender of individuals whenever possible, as it is often crucial in identifying the correct relationship (like differentiating between uncle/aunt, son/daughter, father/mother).
  • Finally, trace the connection between the two individuals whose relationship is asked.

Common relationships include parents, children, siblings, grandparents, grandchildren, uncles, aunts, nephews, nieces, cousins, in-laws (like mother-in-law, father-in-law, sister-in-law, brother-in-law, son-in-law, daughter-in-law).
