Question

In a certain code language,
A = B means 'A is the sister of B',
A $ B means 'A is the brother of B',
A@B means 'A is the wife of B',
and A * B means 'A is the father of B'.

How is A related to K if 'A = R @ F * B $ K'?

The correct answer is
Mother's sister

To determine how A is related to K based on the given relationships, we'll decipher the expression using the code language rules:

  1. Expression Analysis: The expression given is 'A = R @ F * B $ K'.
  2. Breaking Down the Expression:
    • A = R: 'A is the sister of R'.
    • R @ F: 'R is the wife of F'.
    • F * B: 'F is the father of B'.
    • B $ K: 'B is the brother of K'.
  3. Building the Relationships:
    • Since R is the wife of F, the pair F and R could be the parents of B and K.
    • This makes F the father of B and R the mother of B.
    • Since B is the brother of K, we conclude B and K are siblings.
    • A is the sister of R, making A the maternal aunt of both B and K. Hence, A is the sister of their mother, R.
  4. Conclusion: Therefore, A is related to K as Mother's sister.

Thus, the correct answer is Mother's sister.
