In a certain code, ‘X @ Y’ means X is smaller than Y; ‘X & Y’ means X is greater than Y; ‘X # Y’ means X is equal to 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: M & Q, Q @ N, N & P. Conclusions: I. P $ M II. Q $ P. Which of the conclusions is definitely true?
Correct answer A. Neither conclusion I nor II is true
Explanation
Decoding gives M > Q P. I: in M > Q P the signs change direction, so P and M are not related and I fails. II: in Q P the signs change direction, so Q and P are not related and II fails.
