Coding Language Rules Explained

The problem provides specific codes for family relationships:

  • 'A + B' means 'A is the wife of B'.
  • 'A - B' means 'A is the daughter of B'. This implies A is female.
  • 'A * B' means 'A is the father of B'. This implies A is male.
  • 'A / B' means 'A is the brother of B'. This implies A is male.

Analyzing Relationship Expression: W - Q * F * E

We need to find the relationship between W and E using the expression 'W - Q * F * E'. We decode this step-by-step:

Decoding W - Q

According to the rule 'A - B', 'W - Q' means 'W is the daughter of Q'. This confirms W is female.

Decoding Q * F

Using the rule 'A * B', 'Q * F' means 'Q is the father of F'. This indicates Q is male. Since Q is the parent of W and also the parent of F, W and F are siblings.

Decoding F * E

Applying the rule 'A * B' again, 'F * E' means 'F is the father of E'. This confirms F is male.

Deriving W's Relation to E

Let's combine the derived facts:

  • W is the daughter of Q (female).
  • Q is the father of F (male).
  • F is the father of E (male).

From these points, we know W and F are siblings (children of Q). Since W is female, she is the sister of F. Because F is the father of E, W is the sister of E's father.

Final W to E Relationship

W is the sister of E's father. Therefore, W's relationship to E is Father's sister.
