A @ B → A father of B. B # C → B brother of C. C # D → C brother of D. So A is father of B, C, D. D & E → D daughter of E. Since D is child of A, E must be wife of A. Hence A is husband of E.
'P @ Q' means 'P is the sister of Q' 'P & Q' means 'P is the mother of Q' 'P # Q' means 'P is the husband of Q' If 'A # B & C @ D # E' then how is E related to B?
Explanation:
A # B → A husband of B. B & C → B mother of C. So C is daughter of A and B. C @ D → C sister of D, so D is son of A and B. D # E → D husband of E. Hence E is wife of D (son of B), so E is daughter-in-law of B.
Explanation:
Since the man has no brother or sister, 'my father's son' must be the man himself. The statement simplifies to: 'that man's father is myself'. Therefore, the photograph is of his son.
