Question

In a certain code language, A $ B means ‘A is the son of B’ A : B means ‘A is the father of B’ A + B means ‘ A is the wife of B’ A < B means ‘A is the sister of B’ Based on the above, how is T related to N if 'T < R $ U + E : N’?

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

Answer 1

Answer:

B. Sister

T is the sister of N (or T and N are siblings).

Let's decode the expression T < R U + E : N from left to right:

1. T < R: T is the sister of R. (T is Female)

2. R U: R is the son of U. (This means T and R are siblings, and U is their mother/father).

3. U + E: U is the wife of E. (This means U is the mother [Female] and E is the father [Male] of T and R).

4. E : N: E is the father of N.

Conclusion:

Since E and U are the parents of T, R, and N, all three are siblings. Because T is female (T < R), T is the sister of N.
