'A + B' means 'A is the mother of B' 'A - B' means 'A is the husband of B' 'A × B' means 'A is the father of B' 'A ÷ B' means 'A is the daughter of B' Hence, if we consider S + Z - R ÷ H - P + U × M, then which of the following is NOT correct?
U is the son of S.
Understanding Blood Relations with Code Language
This question asks us to analyze a complex blood relation expression based on a given set of codes and identify the statement that is NOT correct among the options provided. We need to decode the expression step-by-step to establish the family relationships.
Decoding the Expression: S + Z - R ÷ H - P + U × M
Let's break down the expression segment by segment using the given codes:
- S + Z: 'A + B' means 'A is the mother of B'. So, S is the mother of Z.
- Z - R: 'A - B' means 'A is the husband of B'. So, Z is the husband of R. This implies R is the wife of Z.
- R ÷ H: 'A ÷ B' means 'A is the daughter of B'. So, R is the daughter of H.
- H - P: 'A - B' means 'A is the husband of B'. So, H is the husband of P. This implies P is the wife of H.
- P + U: 'A + B' means 'A is the mother of B'. So, P is the mother of U.
- U × M: 'A × B' means 'A is the father of B'. So, U is the father of M.
Establishing the Family Relationships
Based on the decoding, we can infer the following relationships:
- S is the mother of Z.
- Z is married to R. (Z is husband, R is wife).
- R is the daughter of H.
- H is married to P. (H is husband, P is wife). This means H and P are the parents of R.
- P is the mother of U. Since H is P's husband, H is the father of U. Thus, H and P are the parents of U.
- U is the father of M.
From these relationships, we can see that R and U are siblings, as they are both children of H and P.
Summary of key relationships:
- S $\leftarrow$ Mother $\leftarrow$ Z
- Z $\leftrightarrow$ Husband/Wife $\leftrightarrow$ R
- R $\leftarrow$ Daughter $\leftarrow$ H
- H $\leftrightarrow$ Husband/Wife $\leftrightarrow$ P
- P $\leftarrow$ Mother $\leftarrow$ U
- U $\leftarrow$ Father $\leftarrow$ M
Also, since H and P are married, H is R's father and P is R's mother. Since H and P are married, U is their child. R and U are siblings.
Combining these: S is Z's mother. Z is R's husband. R is the daughter of H and P. U is the child of H and P. U is the father of M. Therefore, R and U are siblings, and Z is R's husband, making Z the brother-in-law of U. S is the mother of Z, the brother-in-law of U.
Analyzing the Options
Now let's evaluate each given option based on the established family relationships:
Option 1: P is the mother of R.
- We deduced that H and P are the parents of R (H is husband of P, R is daughter of H). P is the wife of H, so P is the mother of R. This statement is correct.
Option 2: H is the paternal grandfather of M.
- U is the father of M. H is the father of U (since H is husband of P, and P is mother of U).
- So, H is the father of M's father (U). This makes H the grandfather of M.
- Since H is male ('H - P' means H is the husband), he is the paternal grandfather. This statement is correct.
Option 3: S is the mother - in - law of R.
- S is the mother of Z. Z is the husband of R.
- The mother of one's husband is the mother-in-law. So, S is the mother-in-law of R. This statement is correct.
Option 4: U is the son of S.
- S is the mother of Z. Z is the husband of R. R is the daughter of H and P. U is the child of H and P.
- This means R and U are siblings. Z is married to R, so Z is U's brother-in-law.
- S is the mother of Z. S is the mother of U's brother-in-law. This does not mean U is the son of S. U is the son or daughter of H and P. This statement is not correct.
Therefore, the statement that is NOT correct is "U is the son of S."
| Statement | Analysis | Correctness |
|---|---|---|
| P is the mother of R. | R is daughter of H. H is husband of P. P is wife of H. So P is mother of R. | Correct |
| H is the paternal grandfather of M. | U is father of M. U is child of H and P. H is husband of P. So H is father of U. H is father of M's father. H is male. H is paternal grandfather of M. | Correct |
| S is the mother - in - law of R. | S is mother of Z. Z is husband of R. S is mother of R's husband. S is mother-in-law of R. | Correct |
| U is the son of S. | S is mother of Z. Z is husband of R. R is daughter of H and P. U is child of H and P. R and U are siblings. Z is U's brother-in-law. S is mother of U's brother-in-law. U is child of H and P, not S. | Not Correct |
Revision Table: Blood Relations Codes
| Code | Meaning | Example |
|---|---|---|
| A + B | A is the mother of B | S + Z means S is mother of Z |
| A - B | A is the husband of B | Z - R means Z is husband of R |
| A × B | A is the father of B | U × M means U is father of M |
| A ÷ B | A is the daughter of B | R ÷ H means R is daughter of H |
Additional Information on Blood Relation Puzzles
Blood relation questions are common in reasoning sections of various exams. They test your ability to understand and decode relationship information presented in different formats, such as codes, diagrams, or direct statements. Here are some tips for solving blood relation puzzles:
- Always start by decoding the given expression or statements.
- Draw a family tree diagram. This visual representation helps in tracing the relationships clearly. Use symbols like circles for females, squares for males, double lines for marriage, and single lines for siblings or parent-child relationships.
- Work through the relationships step-by-step from the beginning to the end of the expression or set of statements.
- Pay close attention to gender information provided by the codes or statements.
- Remember standard family relationships like mother-in-law, paternal grandfather, etc.
- Verify each option against the family tree or the derived relationships to determine its correctness.
Practice with different types of blood relation questions to improve your speed and accuracy in decoding and tracing relationships.
