Question

In a certain code language, A = B means ‘ A is the wife of B’ A : B means ‘A is the son of B’ A * B means ‘A is the brother of B’ A ? B means ‘A is the father of B’ Based on the above, how is S related to T if 'S = M : A ? R * T’?

• A. Brother's wife
• B. Brother's sister
• C. Brother's son
• D. Brother's mother

Answer 1

Answer:

A. Brother's wife

We need to decode the expression 'S = M : A ? R * T' from left to right:

1. S = M $\rightarrow$ S is the wife of M.
   (This means M is the husband, so M is male and S is female).

2. M : A $\rightarrow$ M is the son of A.

3. A ? R $\rightarrow$ A is the father of R.
   (Since M is also A's son, M and R are siblings).

4. R * T $\rightarrow$ R is the brother of T.
   (This means M, R, and T are all siblings, sharing the same father, A).

Conclusion:

Since M is the brother of T, and S is married to M, S is the brother's wife (sister-in-law) of T.
