A% B means 'A is the daughter of B' A = B means 'A is the sister of B' A $ B means 'A is the father of B' If E = F = G $ H = I, then how is G related to E?
Brother
This question involves decoding relationships represented by symbols. We are given a set of rules defining the relationships between two people, say A and B, based on a symbol placed between them. We then need to apply these rules to a longer expression to determine the relationship between two individuals mentioned in the expression.
Understanding the Relationship Codes
Let's first understand what each symbol signifies:
A% Bmeans 'A is the daughter of B'. This tells us A's gender (female) and the relationship (daughter).A = Bmeans 'A is the sister of B'. This tells us A's gender (female) and the relationship (sister).A $ Bmeans 'A is the father of B'. This tells us A's gender (male) and the relationship (father).
Analyzing the Given Expression: E = F = G $ H = I
Now, let's break down the given expression piece by piece, applying the rules:
- E = F: According to the second rule (A = B means A is the sister of B), E is the sister of F. This tells us E is female.
- F = G: According to the second rule (A = B means A is the sister of B), F is the sister of G. This tells us F is female.
- G $ H: According to the third rule (A $ B means A is the father of B), G is the father of H. This tells us G is male.
- H = I: According to the second rule (A = B means A is the sister of B), H is the sister of I. This tells us H is female.
Tracing the Relationship between G and E
We need to find out how G is related to E. Let's connect the relationships we've deduced:
- E is the sister of F.
- F is the sister of G.
If E is the sister of F, and F is the sister of G, this means E, F, and G are siblings. We also know the gender of G from G $ H: G is the father of H, which means G is male.
Since E, F, and G are siblings, and G is male, G is the brother of E (and also the brother of F).
Conclusion
Based on the analysis of the expression E = F = G $ H = I and the given relationship codes, we determined that E, F, and G are siblings, and G is male. Therefore, G is the brother of E.
Let's look at the options provided:
- Brother
- Son's son
- Son's daughter
- Father
Our conclusion that G is the brother of E matches the first option.
| Expression Segment | Relationship | Gender Deduced |
|---|---|---|
| E = F | E is sister of F | E is female |
| F = G | F is sister of G | F is female |
| G $ H | G is father of H | G is male |
| H = I | H is sister of I | H is female |
Combining E = F and F = G, we see that E, F, and G are siblings. Since G is male (from G $ H), G is the brother of E.
Revision Table: Key Relationships
| Symbol | Meaning | A's Gender |
|---|---|---|
| % | A is daughter of B | Female |
| = | A is sister of B | Female |
| $ | A is father of B | Male |
Additional Information: Solving Symbolic Relationship Problems
Solving symbolic relationship problems often involves breaking down complex expressions into smaller, manageable parts. Here are some tips:
- Understand the meaning of each symbol thoroughly, paying attention to which person's relationship and gender are defined by the rule.
- Process the expression sequentially from left to right, determining the relationship between adjacent individuals.
- Keep track of the gender of individuals whenever it can be determined from the rules or the relationships established.
- Combine the direct relationships deduced in each step to find the overall relationship between the target individuals.
- Drawing a family tree diagram can sometimes help visualize the relationships, especially for more complex expressions.
This type of question tests your ability to decode information and logically deduce relationships based on defined rules, which is common in reasoning sections of competitive exams.
