Understanding Blood Relation Coded Relationships
This question requires us to decode specific symbols representing relationships and then determine which sequence of symbols fits into a given expression to achieve a desired relationship.
Decoding the Symbols
Let's first break down the meaning of each symbol as provided:
Z + Ymeans 'Y is the son of Z'. This implies Z is a parent of Y, and Y is male.Z $ Ymeans 'Y is the father of Z'. This implies Z is a child of Y, and Y is male.Y % Zmeans 'Y is the son-in-law of Z'. This implies Y is married to Z's daughter. Y is male, and Z is a parent of Y's spouse.Z – Ymeans 'Y is the wife of Z'. This implies Z is married to Y. Y is female, and Z is male.Y * Zmeans 'Z is the brother of Y'. This implies Y and Z are siblings, and Z is male.Y # Zmeans 'Z is the only sister of Y'. This implies Y and Z are siblings, and Z is female.
Target Relationship and Expression Analysis
Our goal is to find symbols that make the expression W % O – B ? C ? D show that ‘D is the wife of W’.
Let's analyze the given part of the expression:
W % O: According to the ruleY % Zmeans 'Y is the son-in-law of Z', here W is the son-in-law of O. This means W is married to O's daughter. Let's assume O's daughter is X. So, W is married to X, and X is the daughter of O. W is male.O – B: According to the ruleZ – Ymeans 'Y is the wife of Z', here B is the wife of O. This means O is married to B. B is female and O is male. Since W is married to O's daughter (X), and B is O's wife, both O and B are the parents of X. So, X is the daughter of O and B.
So far, we know W is married to the daughter of O and B (let's call her X). We need to replace ? C ? D such that D is the wife of W. This implies D should be X, the daughter of O and B.
Evaluating the Options
Let's test each option by substituting the symbols for the question marks:
Option 1: % and –
Expression becomes W % O – B % C – D
B % C: C is the son-in-law of B. C is married to B's daughter. B's daughter is X (W's wife). So C is married to X.C – D: D is the wife of C.
If C is married to X, and D is the wife of C, this means D is X. But we already established C is married to X. This creates a contradiction where X is married to W and also to C. This option doesn't lead to D being W's wife in a consistent family structure.
Option 2: $ and +
Expression becomes W % O – B $ C + D
B $ C: C is the father of B. This means B is the child of C.B – B: This means B is the wife of O. B is married to O.
These two parts contradict each other in a standard family structure. B cannot be the wife of O and simultaneously the child of C, unless C is a parent of O or B's lineage is traced through O, which isn't directly supported by the codes. This option is unlikely.
Option 3: + and #
Expression becomes W % O – B + C # D
B + C: C is the son of B. Since B is the wife of O, O and B are parents of C. C is male. C is a sibling of X (W's wife).C # D: D is the only sister of C. Since C is the son of O and B, and D is his sister, D is the daughter of O and B. D is female.
We know W is married to O's daughter (X), and D is O's daughter. The rule C # D states D is the only sister of C. Since C is the son of O and B, and X is the daughter of O and B who is married to W, X is a sister of C. If D is the *only* sister of C, then D must be the same person as X. Therefore, D is the daughter of O and B, and D is married to W. This matches the target relationship 'D is the wife of W'. D is female and married to W.
Option 4: + and –
Expression becomes W % O – B + C – D
B + C: C is the son of B. (As in Option 3, C is the son of O and B). C is male. C is a sibling of X (W's wife).C – D: D is the wife of C. D is female. C is married to D.
This means the son of O and B (C) is married to D. We need D to be the wife of W. This interpretation means D is married to C, not W. This option doesn't lead to the target relationship.
Conclusion
Based on the analysis, only Option 3, using the symbols '+' and '#', results in the relationship 'D is the wife of W'.
| Expression Part | Symbols | Relationship Implied | Analysis |
|---|---|---|---|
W % O |
% | W is son-in-law of O | W is married to O's daughter (X). W is male. O is parent of X. |
O – B |
– | B is wife of O | O is married to B. B is female, O is male. O and B are parents of X. |
B + C (Option 3) |
+ | C is son of B | C is son of O and B. C is male. C is sibling of X. |
C # D (Option 3) |
# | D is the only sister of C | D is daughter of O and B. D is female. D is sibling of C. Since D is the only sister of C and X is also a sister of C, D must be X. |
| Conclusion: If D = X, and W is married to X, then W is married to D. D is female. Thus, D is the wife of W. | |||
Revision Table: Key Symbol Meanings
| Symbol | Relationship (X Symbol Y) | Interpretation |
|---|---|---|
| + | X + Y | Y is son of X |
| $ | X $ Y | Y is father of X |
| % | X % Y | X is son-in-law of Y |
| – | X – Y | Y is wife of X |
| * | X * Y | Y is brother of X |
| # | X # Y | Y is the only sister of X |
Additional Information: Solving Blood Relation Puzzles
Blood relation questions often involve decoding relationships expressed through symbols or codes. To solve these effectively, follow these steps:
- Decode Each Symbol: Clearly write down what each symbol means in terms of standard relationships (father, mother, sister, brother, wife, son, daughter, etc.). Pay attention to the order of the individuals (e.g., X is the father of Y vs. Y is the father of X).
- Analyze the Expression: Break the given expression into smaller parts based on the symbols.
- Build a Family Tree/Diagram: Use diagrams or mental mapping to represent the relationships derived from the expression. Use symbols like arrows (for parent-child), double lines (for marriage), and single lines (for siblings). Indicate gender where known.
- Connect the Relationships: Link the individuals based on the decoded symbols.
- Evaluate the Target Relationship: Determine what relationship needs to be proven.
- Test Options (if applicable): If question marks are involved, substitute the options one by one into the expression. Extend the family tree based on the substituted symbols.
- Verify the Target: Check if the extended family tree/relationships satisfy the target relationship.
- Consider Constraints: Note any constraints like "only son" or "only sister", as these are crucial.
Using a step-by-step approach and visualizing the relationships helps in solving complex blood relation puzzles accurately.
