In a certain code, ‘X % Y’ means X is equal to Y; ‘X & Y’ means X is either greater than or equal to Y; ‘X @ Y’ means X is either smaller than or equal to Y; ‘X # Y’ means X is smaller than Y; ‘X $ Y’ means X is greater than Y. Statements: E % C, C $ F, F @ A, A @ D, D # B. Conclusions: I. B $ F II. D & F. Which of the conclusions is definitely true?
Correct answer B. Both conclusions I and II are true
Explanation
Decoding gives E = C > F ≤ A ≤ D < B. I: F ≤ A ≤ D F, so I is true. II: F ≤ A ≤ D gives D ≥ F, so II is true.
