'A + B' means 'B is the father of A'
'A - B' means 'B is the mother of A'
'A # B' means 'B is the sister of A'
'A & B' means 'B is the wife of A'
If A# B + C & D - E, then how is E related to A?
Blood Relation Codes Explained
This question tests your ability to decode relationships based on symbolic representations. Each symbol has a specific meaning defining a family connection. Let's understand each one:
- A + B means 'B is the father of A'. This indicates that the person on the right side of the '+' symbol (B) is the father of the person on the left side (A).
- A - B means 'B is the mother of A'. Similarly, the person on the right side of the '-' symbol (B) is the mother of the person on the left side (A).
- A # B means 'B is the sister of A'. This signifies that the person on the right side of the '#' symbol (B) is the sister of the person on the left side (A).
- A & B means 'B is the wife of A'. This shows that the person on the right side of the '&' symbol (B) is the wife of the person on the left side (A).
Decoding the Expression: A # B + C & D - E
Now, we will systematically decode the given expression A # B + C & D - E using the relationship codes provided. This process helps build a clear family tree.
- A # B: Based on the rule 'A # B' means 'B is the sister of A'. So, A and B are siblings, and B is female.
- B + C: The rule 'A + B' means 'B is the father of A'. Applying this to 'B + C', we get 'C is the father of B'. Since A and B are siblings, C is also the father of A.
- C & D: The rule 'A & B' means 'B is the wife of A'. Applying this to 'C & D', we get 'D is the wife of C'. As C is the father of A, his wife D must be the mother of A.
- D - E: The rule 'A - B' means 'B is the mother of A'. Applying this to 'D - E', we get 'E is the mother of D'.
Final Relationship Determination
Let's combine the deduced relationships to find out how E is related to A:
- From the previous steps, we determined that D is the mother of A.
- We also found that E is the mother of D.
Therefore, E is the mother of A's mother. This relationship defines E as A's maternal grandmother.
The question asks for the relationship of E to A. Based on our step-by-step analysis, E is the mother of A's mother.
