Son-in-law
Solving the Blood Relation Puzzle
Let's break down the given expression and the codes to determine the relationship between J and S.
The given codes are:
- A + B means A is the father of B.
- A * B means A is the daughter of B.
- A % B means A is the brother of B.
The expression we need to analyze is: J + T % N % C * L * S
We will decode the expression step by step from left to right:
- J + T: According to the rule A + B means A is the father of B, this means J is the father of T. From this, we know J is male.
- T % N: According to the rule A % B means A is the brother of B, this means T is the brother of N. From this, we know T is male. T and N are siblings.
- N % C: According to the rule A % B means A is the brother of B, this means N is the brother of C. From this, we know N is male. N and C are siblings. Since T is brother of N, and N is brother of C, T, N, and C are all siblings.
- C * L: According to the rule A * B means A is the daughter of B, this means C is the daughter of L. From this, we know C is female. Since J is the father of C (as J is father of T, N, C), and C is the daughter of L, L must be the mother of C. Therefore, J and L are husband and wife, with J being the father and L being the mother of T, N, and C. L is female.
- L * S: According to the rule A * B means A is the daughter of B, this means L is the daughter of S. From this, we know L is female. S is the parent of L (either father or mother).
Let's summarize the relationships we have found:
- J is the father of T, N, and C. (J is male)
- T is the brother of N and C. (T is male)
- N is the brother of T and C. (N is male)
- C is the daughter of J and L. (C is female)
- L is the mother of T, N, and C, and the wife of J. (L is female)
- L is the daughter of S. (S is the parent of L)
The question asks: How is J related to S?
We know that J is married to L, and L is the daughter of S.
If a person (L) is the daughter of someone (S), then the husband of that person (J) is the son-in-law of that someone (S).
Therefore, J is the son-in-law of S.
| Relation | Inference |
|---|---|
| J + T | J is father of T (J is male) |
| T % N | T is brother of N (T is male) |
| N % C | N is brother of C (N is male) |
| C * L | C is daughter of L (C is female). Since J is father of C, L is mother of C. |
| L * S | L is daughter of S (L is female) |
| J and L | Married (Husband and Wife) |
| J to S | J is husband of L, and L is daughter of S. Thus, J is son-in-law of S. |
