Understanding the Blood Relation Code Language
This blood relation question uses a coded language where symbols represent specific relationships. Let's break down the meaning of each symbol:
- A + B means 'A is the wife of B'. This tells us that A is female and B is male. A and B are a couple.
- A - B means 'A is the father of B'. This tells us that A is male and B is A's child.
- A × B means 'A is the sister of B'. This tells us that A is female and A and B are siblings.
- A ÷ B means 'A is the brother of B'. This tells us that A is male and A and B are siblings.
Analyzing the Given Expression: V ÷ W + X - Y × Z
We need to determine the relationship between V and Z based on the expression 'V ÷ W + X - Y × Z'. We can decode this expression segment by segment from left to right:
- V ÷ W: According to the code, A ÷ B means 'A is the brother of B'. So, V is the brother of W. This tells us that V is male.
- W + X: According to the code, A + B means 'A is the wife of B'. So, W is the wife of X. This tells us that W is female and X is male. W and X are married.
- X - Y: According to the code, A - B means 'A is the father of B'. So, X is the father of Y. Since W is the wife of X, W must be the mother of Y.
- Y × Z: According to the code, A × B means 'A is the sister of B'. So, Y is the sister of Z. This tells us that Y is female. Since Y is the child of X and W, Z is also a child of X and W. Y and Z are siblings.
Building the Family Relationships
Based on the analysis of the expression, we can establish the following relationships:
| Relationship | Interpretation | Gender (if known) |
|---|---|---|
| V ÷ W | V is brother of W | V is male |
| W + X | W is wife of X | W is female, X is male |
| X - Y | X is father of Y | X is male (already known), Y's gender is determined later |
| Y × Z | Y is sister of Z | Y is female, Z's gender is not specified |
Combining these relationships:
- V is the brother of W.
- W is the wife of X.
- X is the father of Y. (Therefore, W is the mother of Y).
- Y is the sister of Z. (Therefore, Y and Z are siblings, and W and X are also the parents of Z).
Determining How V is Related to Z
We want to find the relationship between V and Z. From our analysis:
- V is the brother of W.
- W is the mother of Z.
If W is the mother of Z, and V is the brother of W, then V is the brother of Z's mother. The brother of one's mother is called the maternal uncle, or mother's brother.
Therefore, V is related to Z as Z's mother's brother.
Revision Table: Key Relationships
| Individuals | Relationship |
|---|---|
| V and W | V is brother of W |
| W and X | W is wife of X |
| X and W | Parents of Y and Z |
| Y and Z | Siblings (Y is Z's sister) |
| W and Z | W is mother of Z |
| V and Z | V is brother of W (Z's mother) |
Additional Information: Solving Blood Relation Questions
Blood relation questions are common in logical reasoning sections of competitive exams. They test your ability to decipher coded relationships and construct family trees. Here are some tips for solving such questions:
- Read the coded language rules carefully, noting the gender implied by each relationship.
- Break down the given expression into smaller segments based on the operators.
- Determine the direct relationship between the two individuals in each segment.
- Link the segments together to build a complete chain of relationships or a family tree diagram.
- Work step-by-step to connect the individuals whose relationship you need to find.
- Pay attention to gender, as it is crucial in determining the exact relationship (e.g., uncle vs. aunt).
