Zorluk: OrtaBlood Relations

At a charity dinner, a woman named Sarah points to a man across the room and tells her friend, 'His wife's father-in-law is the husband of my husband's mother.' If it is known that Sarah's husband is his parents' only son, what is the exact relationship of the man to Sarah?

Cevap: Husband / husband / Spouse / spouse / Her husband

Cevap

Husband
Breaking down Sarah's statement: 'the husband of my husband's mother' refers to Sarah's father-in-law (the father of her husband). Therefore, 'His wife's father-in-law' must also be Sarah's father-in-law. For the man's wife to have the same father-in-law as Sarah, the man's father must be Sarah's father-in-law. This means the man is either Sarah's husband's brother, or he is Sarah's husband himself. Since we are given that Sarah's husband is his parents' only son, he cannot have any brothers. Thus, the man Sarah is pointing to must be her own husband.

Adım Adım Çözüm

1
Identify the person described in the second half of Sarah's statement: 'the husband of my husband's mother'.
Sarah's husband's mother is her mother-in-law. The husband of her mother-in-law is Sarah's father-in-law (her husband's father).
Breaking down the relational chain from Sarah's perspective establishes the target identity.
2
Identify the person described in the first half of the statement: 'His wife's father-in-law'.
For any married man, his wife's father-in-law is his own father.
The father-in-law of a wife is by definition the father of her husband.
3
Equate the two identities found in steps 1 and 2.
The man's father is the exact same person as Sarah's husband's father.
The statement uses the word 'is' to connect both descriptions, meaning they refer to the same individual.
4
Determine the relationship based on the constraint that Sarah's husband is his parents' only son.
Since the man and Sarah's husband share the same father, they must be brothers, or they must be the same person. Because Sarah's husband is an only son, there are no brothers. Therefore, the man must be Sarah's husband himself.
Applying the final logical constraint eliminates all other possibilities.
