Decoding the Family Relationships

This question is a classic blood relation puzzle that requires us to decode a series of relationship codes and apply them to a specific expression to determine the connection between two individuals, Z and S.

Understanding the Relationship Codes

Let's first understand the meaning of each symbol as defined:

  • A + B: A is the mother of B
  • A $\div$ B: A is the wife of B
  • A & B: A is the brother of B
  • A $\times$ B: A is the sister of B
  • A - B: A is the father of B

Applying the Codes to the Expression

We need to decipher the expression 'A $\times$ Z + P & R $\div$ Q - S' step by step.

  1. A $\times$ Z: This means 'A is the sister of Z'. From this, we know A is female, but Z's gender is not yet determined.
  2. Z + P: This means 'Z is the mother of P'. This tells us that Z is female. Since Z is the mother of P, P is Z's child.
  3. P & R: This means 'P is the brother of R'. This tells us P is male. Since P and R are siblings, and Z is the mother of P, Z must also be the mother of R.
  4. R $\div$ Q: This means 'R is the wife of Q'. This confirms R is female. Since R is married to Q, Q must be male.
  5. Q - S: This means 'Q is the father of S'. This confirms Q is male and S is Q's child.

Establishing the Link Between Z and S

Now let's combine these deduced relationships to find out how Z is related to S:

  • From step 2 and 3, we established that Z is the mother of R.
  • From step 4, we know that R is the wife of Q.
  • Combining these, Z is the mother of R, and R is married to Q. Therefore, Z is the mother-in-law of Q.
  • From step 5, we know that Q is the father of S.
  • Since Z is the mother of R, and R is the wife of Q (who is the father of S), Z is the mother of S's mother (R).
  • Therefore, Z is the mother's mother of S.

Conclusion

Based on the step-by-step decoding of the expression and the given relationship codes, Z is the mother's mother of S.
