Solving Symbol Based Blood Relations: Understanding T × V + Z

This question involves decoding relationships expressed using specific symbols. We are given a set of rules defining what each symbol means in terms of family relationships. Our goal is to apply these rules to the given expression 'T × V + Z' and determine the relationship between T and Z.

Understanding the Given Rules for Blood Relations

Here are the definitions of the symbols provided:

• ‘R+S’ means ‘R is the daughter of S’.
• ‘R−S’ means ‘R is the husband of S’.
• ‘R × S’ means ‘R is the brother of S’.

Analyzing the Expression: T × V + Z

Let's break down the expression 'T × V + Z' into its parts based on the given rules.

The expression has two parts joined together:

1. T × V: Using the rule ‘R × S’ means ‘R is the brother of S’, we substitute R with T and S with V. This tells us that T is the brother of V. From this, we know T is male.
2. V + Z: Using the rule ‘R + S’ means ‘R is the daughter of S’, we substitute R with V and S with Z. This tells us that V is the daughter of Z. From this, we know that Z is a parent of V (either father or mother).

Combining the Relationships to Find T's Relation to Z

Now we combine the information we derived from each part of the expression:

• We know T is the brother of V.
• We know V is the daughter of Z.

If V is the daughter of Z, then Z is the parent of V. Since T is V's brother, T is also a child of Z. Because we established that T is male (from 'T × V'), and T is a child of Z, T must be the son of Z.

Conclusion on the Relationship between T and Z

Based on the analysis of the expression 'T × V + Z', we have determined that T is the son of Z.

Evaluating the Options

Let's look at the given options and see which one matches our conclusion:

1. T is the uncle of Z. (Incorrect)
2. T is the father of Z. (Incorrect)
3. T is the son of Z. (Correct)
4. T is the brother of Z. (Incorrect)

The relationship 'T is the son of Z' correctly matches option 3.

Additional Information on Solving Blood Relation Puzzles

Blood relation questions are common in logic and reasoning sections of competitive exams. Symbol-based problems require careful decoding of each part of the expression.

• Step-by-step decoding: Always break down the given expression into smaller segments based on the symbols.
• Determine Gender: Identify the gender of individuals whenever possible from the relationship given. For example, 'R is the daughter of S' tells us R is female. 'R is the brother of S' tells us R is male. 'R is the husband of S' tells us R is male and S is female.
• Combine relationships: Link the relationships derived from each segment to build a family tree or chain of relations.
• Verify Options: Once you determine the relationship, check which option correctly states it.

Understanding the basic family structure and relationships is crucial for solving blood relation problems effectively.
