- AX @ Z
- BZ @ X
- CX # Z
- D
Step-by-Step Solution
X < Y and Y ≤ Z give X < Z, which is coded 'X @ Z'. The other three contradict X < Z.
Answer: A) X @ Z
Using the code '*' = greater than, '@' = less than, '#' = equal to, '^' = greater than or equal to and '~' = less than or equal to: if 'X @ Y' and 'Y ~ Z' are true, which of these must be true?
