  • $P#Q$ means Q is the sister of P.
  • $P&Q$ means Q is the son of P.

Step-by-Step Analysis

We need to decode the expression $A & B @ C & D # E$.

  1. $A & B$: This means B is the son of A. A is B's parent.
  2. $B @ C$: This means C is the mother of B.
  3. Combining (1) and (2): Since C is the mother of B, and A is B's parent, A must be the father of B.
  4. $C & D$: This means D is the son of C. C is D's parent.
  5. $D # E$: This means E is the sister of D. D and E are siblings.
  6. Combining (4) and (5): Since C is the mother of D, and D and E are siblings, C is also the mother of E.
  7. Conclusion: From (3), A is the father of B. From (2) and (6), C is the mother of B, D, and E. Since A is the father of B (whose mother is C), A is the father of all of C's children, including E.

Final Relationship

A is the father of E.
