Decoding Family Relationships from Coded Expressions
The question requires us to determine the relationship between S and P using a given coding scheme for family relations. The expression is $S - K ÷ T × V + P$.
Step-by-Step Relationship Analysis
- $S - K$: 'A - B' means 'A is the wife of B'. Therefore, S is the wife of K. This tells us S is female.
- $K ÷ T$: 'A ÷ B' means 'A is the father of B'. Thus, K is the father of T. Since S is K's wife, S is the mother of T.
- $T × V$: 'A × B' means 'A is the sister of B'. So, T is the sister of V. Since S is the mother of T, and T and V are siblings, S is also the mother of V.
- $V + P$: 'A + B' means 'A is the mother of B'. Hence, V is the mother of P.
Determining the S to P Relation
From the steps above:
- S is the mother of V.
- V is the mother of P.
Combining these, S is the mother of P's mother. This relationship is known as the maternal grandmother.
Therefore, S is the Mother's mother of P.
