The correct Answer is:
To solve the problem, we need to analyze the given relationships and determine which option correctly represents "R is the son of M." ### Step-by-Step Solution: 1. **Understanding the Symbols**: - 'P + Q' means 'P is the brother of Q'. - 'P x Q' means 'P is the father of Q'. - 'P - Q' means 'P is the mother of Q'. 2. **Evaluating Each Option**: We need to evaluate each option to see which one correctly represents "R is the son of M". **Option 1: M x S x R** - M x S means M is the father of S. - S x R means S is the father of R. - Therefore, R is the grandson of M, not the son. **(Incorrect)** **Option 2: M + R x S** - M + R means M is the brother of R. - R x S means R is the father of S. - Therefore, M is the brother of R, and R is the father of S. This does not imply that R is the son of M. **(Incorrect)** **Option 3: M x S - R** - M x S means M is the father of S. - S - R means S is the mother of R. - Therefore, M is the father of S, and S is the mother of R, which implies that R is the son of M. **(Correct)** 3. **Conclusion**: After evaluating all options, we find that **Option 3** correctly represents "R is the son of M". ### Final Answer: The correct representation of "R is the son of M" is **Option 3: M x S - R**. ---
