Decoding Relation Codes
The problem provides specific codes for relationship symbols:
- '+' means 'son'
- '-' means 'sister'
- 'x' means 'wife'
- '÷' means 'father'
Analyzing the Expression: Q + E ÷ R – C x D
We break down the given expression step-by-step to determine the relationships:
- Q + E: Q is the son of E. (This establishes Q is male).
- E ÷ R: E is the father of R. (This establishes E is male).
- R – C: R is the sister of C. (This establishes R is female).
- C x D: C is the wife of D. (This establishes C is female and D is male).
Constructing the Family Tree
Based on the decoded relationships:
- Q is the son of E.
- E is the father of R. Since Q is also E's child, Q and R are siblings.
- R is the sister of C. This means Q, R, and C are siblings.
- C is the wife of D.
Determining Q's Relation to D
From the analysis:
- Q is the brother of C.
- C is the wife of D.
- Therefore, Q is the brother of D's wife.
This means Q is the Wife's brother to D.
