Family Relation Logic Puzzle Analysis

This solution decodes a family relationship puzzle based on symbolic representations.

Symbol Definitions

  • $C $ D$ means C is the husband of D (C is male, D is female).
  • $C & D$ means C is the mother of D (C is female).
  • $C % D$ means C is the son of D (C is male).

Expression Breakdown: $X % Z $ W & Y$

  1. $X % Z$: This translates to 'X is the son of Z'.
    • X is male.
    • Z is the parent of X.
  2. $Z $ W$: This translates to 'Z is the husband of W'.
    • Z is male.
    • W is female (wife of Z).
    Combining with the previous step, since Z is the husband of W and the parent of X, W must be the mother of X. Therefore, X is the son of W.
  3. $W & Y$: This translates to 'W is the mother of Y'.
    • W is female.
    • Y is the child of W.

Applying the Constraint

The condition states that 'W has only one son'.

  • From step 2, we established that X is the son of W.
  • Since X is the only son W has, and Y is also a child of W (from step 3), Y must be a daughter.

Final Relationship

Based on the analysis:

  • X is the son of W.
  • Y is the daughter of W.
  • Both X and Y are children of W.
  • Therefore, X is the brother of Y.
