- BP is the grandmother of S
- CP is the mother of S
- DS is the grandmother of P
Solution & Step-by-step Explanation
Let's break down the coded expression P @ Q * R # S step-by-step from right to left:
1. R # S \rightarrow R is the husband of S. (R is Male, S is Female; they are a married couple).
2. Q is the daughter of R. Since R and S are married, Q is also the daughter of S.
3. P is the son of Q.
Since Q is the mother of P, and S is the mother of Q, S is the maternal grandmother of P.
Hence, S is the grandmother of P.
1. R # S \rightarrow R is the husband of S. (R is Male, S is Female; they are a married couple).
2. Q is the daughter of R. Since R and S are married, Q is also the daughter of S.
3. P is the son of Q.
Since Q is the mother of P, and S is the mother of Q, S is the maternal grandmother of P.
Hence, S is the grandmother of P.
