In a certain code, ‘X % Y’ means X is greater than Y; ‘X $ Y’ means X is either greater than or equal to Y; ‘X @ Y’ means X is smaller than Y; ‘X # Y’ means X is either smaller than or equal to Y; ‘X & Y’ means X is equal to Y. Statements: O # N, N # K, K @ L, L @ J, J @ M. Conclusions: I. M $ O II. N $ J. Which of the conclusions is definitely true?
Correct answer A. Only conclusion I is true
Explanation
Decoding gives O ≤ N ≤ K < L < J < M. I: O ≤ N ≤ K < L < J O, so I is true. II: N ≤ K < L < J gives only N < J, so II (N ≥ J) does not follow.
