Question

In a certain code language, 'A ? B' means ‘A is the wife of B’, 'A × B' means ‘A is the brother of B’, 'A : B' means ‘A is the father of B’ and 'A − B' means ‘A is the son of B’. How is L related to M if 'E − G ? L : K × M’?

• A. Father
• B. Brother
• C. Mother
• D. Son

Answer 1

Answer:

A. Father

L is the father of M.

Let's break down the expression 'E − G ? L : K × M' from left to right:

1. E − G $\rightarrow$ E is the son of G.

2. G ? L $\rightarrow$ G is the wife of L.

   • Inference: Since G is the wife of L, L must be the husband (male). Together, L and G are the parents of E.

3. L : K $\rightarrow$ L is the father of K.

   • Inference: K and E are siblings.

4. K × M $\rightarrow$ K is the brother of M.

   • Inference: M is another sibling in the family (child of L and G).

Conclusion:

Since L is the father of K, and K is the brother of M, L is the father of M.
