Decoding the Relationships
We are given a coded language for family relationships:
- $A @ B$ means A is the son of B.
- $A # B$ means A is the sister of B.
- $A + B$ means A is the wife of B.
- $A % B$ means A is the father of B.
We need to find the relationship between E and B using the expression $E + R @ D % N # B$.
Step-by-Step Analysis
- E + R: This translates to 'E is the wife of R'. This means R is the husband of E.
- R @ D: This translates to 'R is the son of D'. So, D is a parent of R.
- D % N: This translates to 'D is the father of N'. Since D is the father of N, and R is the son of D, D is the father of both R and N.
- N # B: This translates to 'N is the sister of B'. This means N and B are siblings, and their father is D.
Determining E's Relation to B
From the steps above:
- E is the wife of R.
- R, N, and B are children of D (R is son, N is daughter, B is sibling of N). D is the father.
- Therefore, R is the brother of B.
- Since E is the wife of R, and R is the brother of B, E is the brother's wife of B.
Thus, E is related to B as her brother's wife.
