Analyzing Blood Relations from the Expression
This question asks us to determine the relationship between two individuals, E and G, based on a coded expression representing blood relations. We need to decode each part of the given expression step-by-step using the provided definitions.
Understanding the Blood Relation Codes
Let's first review the meaning of each symbol:
A + Bmeans A is the sister of B.A - Bmeans A is the father of B.A × Bmeans A is the son of B.A ÷ Bmeans A is the wife of B.
Decoding the Given Expression: E ÷ F - H + J ÷ G × D
We will break down the expression from left to right to establish the relationships:
E ÷ F: Based on the code, this means E is the wife of F. This tells us E is female and F is male, and they are married.F - H: Based on the code, this means F is the father of H. Since E is the wife of F, H is the child of both E and F.H + J: Based on the code, this means H is the sister of J. This tells us H is female, and J is H's sibling. Since F is the father of H, F is also the father of J. Similarly, E is the mother of H, so E is also the mother of J.J ÷ G: Based on the code, this means J is the wife of G. This tells us J is female and G is male, and they are married. We already know J is the daughter of E and F.G × D: Based on the code, this means G is the son of D. This tells us G is male, and D is a parent of G. While this information relates to D, it also confirms G's gender (male), which we already deduced fromJ ÷ G. This part of the expression is not directly needed to find the relation between E and G, but it helps confirm G's status in the family structure.
Connecting the Relationships to Find E's Relation to G
From our decoding, we have established the following key relationships:
- E is the mother of J.
- J is the wife of G.
If E is the mother of J, and J is married to G, then E is the mother of G's wife. The mother of one's wife is called the mother-in-law.
Conclusion: E's Relationship to G
Therefore, E is the mother-in-law of G.
Revision Table: Summary of Relationships
Let's summarize the relationships we deduced from the expression:
| Part of Expression | Relationship | Implication |
|---|---|---|
E ÷ F |
E is wife of F | E (Female), F (Male), Married |
F - H |
F is father of H | H is child of F and E |
H + J |
H is sister of J | H (Female), J is child of F and E |
J ÷ G |
J is wife of G | J (Female), G (Male), Married. J is daughter of E and F. |
G × D |
G is son of D | D is a parent of G. |
From the table, we see that J is the daughter of E and F, and J is married to G. This confirms that E is the mother of J, who is married to G. Thus, E is G's mother-in-law.
Additional Information: Solving Blood Relation Puzzles
Blood relation questions test your ability to understand and interpret relationships within a family. When solving such puzzles, it's helpful to:
- Break down complex expressions into smaller parts.
- Use diagrams or family trees to visualize the relationships, especially for more complicated problems. Assign genders where possible based on the relation codes.
- Work step-by-step, connecting each new piece of information to the existing relationships.
- Pay close attention to the phrasing of the final question (e.g., "How is A related to B?" versus "How is B related to A?").
- Practice with different types of coding and relationship structures.
