Question

In a certain code language, A x B means ‘A is the mother of B’, A - B means ‘A is the brother of B’, A + B means ‘A is the wife of B’, A = B means ‘A is the father of B’. Based on the above, how is T related to K if ‘T x D – S + W = K’?

• A. Mother's sister
• B. Mother's mother
• C. Mother
• D. Sister

Answer 1

Answer:

B. Mother's mother

To find out how T is related to K, let's decode the expression ‘T x D – S + W = K’ step-by-step from left to right:

1. Decoding the Expression:

• $T \times D$: T is the mother of D.

• $D - S$: D is the brother of S.
  (Since T is D's mother, T is also the mother of S).

• $S + W$: S is the wife of W.
  (This means S is female, W is male, and T is the mother of the wife, S).

• $W = K$: W is the father of K.

2. Analyzing the Relationships:

• S and W are the parents of K (S is the mother, W is the father).

• T is the mother of S.

Therefore, T is the mother of K's mother.

Final Answer

T is the maternal grandmother of K (or mother's mother).
