Solving Blood Relation Puzzles
Blood relation problems test your ability to understand and decode relationships based on given information. In this question, symbols represent specific relationships, and we need to build a family structure from a coded expression to determine the correct relationships between individuals.
Understanding the Coded Relationships
Let's first understand what each symbol in the problem represents:
- @ means 'A is the sister of B'. (A is female)
- & means 'A is the brother of B'. (A is male)
- # means 'A is the wife of B'. (A is female, B is male)
- ^ means 'A is the mother of B'. (A is female)
- + means 'A is the father of B'. (A is male)
Analyzing the Coded Expression H @ V @ U # W & E ^ X # Z & R ^ S
We will break down the given expression step by step to build the relationships:
- H @ V: H is the sister of V. (H is female)
- V @ U: V is the sister of U. (V is female)
- From steps 1 and 2, H and V are sisters, and V and U are sisters. This means H, V, and U are all sisters. (H, V, U are female)
- U # W: U is the wife of W. (U is female, W is male)
- W & E: W is the brother of E. (W is male)
- From steps 4 and 5, U is married to W, and W is the brother of E. (W is male, E's gender is unknown from this part alone)
- E ^ X: E is the mother of X. (E is female)
- From step 6 and 7, W is the brother of E, and E is the mother of X. E is female. (E is female, X's gender is unknown from this part alone)
- X # Z: X is the wife of Z. (X is female, Z is male)
- From step 7 and 9, E is the mother of X, and X is the wife of Z. X is female, Z is male.
- Z & R: Z is the brother of R. (Z is male)
- From step 9 and 11, Z is married to X and Z is the brother of R. (Z is male, R's gender is unknown from this part alone)
- R ^ S: R is the mother of S. (R is female)
- From step 11 and 13, Z is the brother of R, and R is the mother of S. R is female. (R is female, S's gender is unknown)
Summarizing the Derived Relationships
Based on the analysis of the coded expression, here are the key relationships:
- H, V, and U are sisters. (All female)
- U is the wife of W. (U is female, W is male)
- W is the brother of E. (W is male, E is female)
- E is the mother of X. (E is female, X is female)
- X is the wife of Z. (X is female, Z is male)
- Z is the brother of R. (Z is male, R is female)
- R is the mother of S. (R is female, S's gender is unknown)
Evaluating the Given Statements
Now let's examine each statement provided in the options and check its correctness against the derived relationships:
- Statement 1: Z is the maternal grandfather of S.
S's mother is R (R ^ S). Z is the brother of R (Z & R). This means Z is S's mother's brother. A mother's brother is the maternal uncle. Therefore, Z is the maternal uncle of S, not the maternal grandfather. This statement is NOT correct.
- Statement 2: W is the husband of U.
The expression U # W means 'U is the wife of W'. If U is the wife of W, it means W is the husband of U. This statement is correct.
- Statement 3: E is the mother-in-law of Z.
Z is married to X (X # Z), which means Z is the husband of X. The mother-in-law of a husband is the mother of his wife. X's mother is E (E ^ X). Therefore, E is the mother of X, who is Z's wife. This makes E the mother-in-law of Z. This statement is correct.
- Statement 4: U is the sister of H.
We deduced earlier that H, V, and U are all sisters based on H @ V and V @ U, and confirming U's female gender from U # W. If H, V, and U are sisters, then U is indeed the sister of H. This statement is correct.
Identifying the Incorrect Statement
Based on our evaluation, the statement that is NOT correct is "Z is the maternal grandfather of S", as Z is the maternal uncle of S.
| Statement | Relationship Check | Correct? |
|---|---|---|
| Z is the maternal grandfather of S. | S's mother is R. Z is R's brother. Z is S's maternal uncle. | No |
| W is the husband of U. | U # W means U is wife of W. | Yes |
| E is the mother-in-law of Z. | Z's wife is X. E is mother of X. E is Z's mother-in-law. | Yes |
| U is the sister of H. | H @ V means H sister of V. V @ U means V sister of U. U # W means U is female. H, V, U are sisters. | Yes |

Additional Information on Blood Relations
Solving blood relation problems often involves drawing a family tree or diagram. This helps visualize the connections between individuals and generations. Remember to pay close attention to the gender indicators provided by the symbols, as they are crucial for correctly identifying relationships like uncle vs. aunt, grandfather vs. grandmother, etc. Some relationships like 'sibling' might require deducing gender from other parts of the expression.
