In a code, '@' means ≥, '#' means ≤, '$' means >, '%' means <, and '&' means =. Statements: X @ Y, Y & Z. Conclusions: I. X > Z.
II. X = Z. Which conclusion follows?

Competition practiceInequalities
  • ANeither follows
  • BOnly II follows
  • CEither I or II follows
  • DOnly I follows

Step-by-Step Solution

X ≥ Y = Z gives X ≥ Z, which means either X > Z or X = Z. Neither is certain alone, but together they cover the guaranteed relation, so either I or II follows.
Answer: C) Either I or II follows
