In a certain code, ‘X @ Y’ means X is smaller than Y; ‘X # Y’ means X is equal to Y; ‘X $ Y’ means X is greater than Y; ‘X & Y’ means X is either smaller than or equal to Y; ‘X % Y’ means X is either greater than or equal to Y. Statements: N $ K, K # M, M @ J. Conclusions: I. J % M II. J $ N. Which of the conclusions is definitely true?
Correct answer D. Only conclusion I is true
Explanation
Decoding gives N > K = M < J. I: M M, so I is true. II: in N > K = M < J the signs change direction, so J and N are not related and II fails.
