Blood Relations Reasoning: Mother-in-Law Puzzle
This solution decodes relationship symbols to solve a blood relations puzzle.
Relationship Codes Explained
- \(G + H\) means G is the son of H.
- \(G - H\) means G is the husband of H.
- \(G * H\) means G is the sister of H.
Analyzing Expressions for J as N's Mother-in-Law
To find J as the mother-in-law of N, J must be the mother of N's spouse.
Option 1: \(N - M * K + J\)
- \(N - M\) implies N is the husband of M. Thus, M is N's spouse (female).
- \(M * K\) implies M is the sister of K.
- \(K + J\) implies K is the son of J. Thus, J is the parent of K.
Deduction: Since M is K's sister and J is K's parent, J is also M's parent. As N is married to M, J is the parent of N's wife. Therefore, J is the mother-in-law of N.
Option 2: \(N * M - K + J\)
- \(N * M\) implies N is the sister of M (N is female).
- \(M - K\) implies M is the husband of K (M is male).
- \(K + J\) implies K is the son of J (J is K's parent).
Deduction: J is the parent of K, and K is the wife of M. N is M's sister. J is the parent of N's brother's wife, not N's mother-in-law.
Option 3: \(N + M - K * J\)
- \(N + M\) implies N is the son of M (N is male).
- \(M - K\) implies M is the husband of K (M is male).
- \(K * J\) implies K is the sister of J (K is female).
Deduction: M is the husband of K. N is the son of M. K is J's sister. N is the son of M (father), and K is M's wife. J is K's sibling. J is the maternal aunt/uncle of N, not the mother-in-law.
Option 4: \(N + M * K - J\)
- \(N + M\) implies N is the son of M (N is male).
- \(M * K\) implies M is the sister of K (M is female).
- \(K - J\) implies K is the husband of J (K is male).
Deduction: M is N's mother. M is K's sister. K is J's husband. N's maternal uncle (K) is married to J. J is the maternal aunt by marriage to N, not the mother-in-law.
Final Determination
Option 1 uniquely satisfies the condition that J is the mother-in-law of N by establishing J as the parent of N's wife.
