In a certain code, ‘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 smaller than Y; ‘X # Y’ means X is either greater than or equal to Y. Statements: Q $ R, R $ S, S & U, U % P, P $ T. Conclusions: I. R % P II. P & T. Which of the conclusions is definitely true?
Correct answer D. Neither conclusion I nor II is true
Explanation
Decoding gives Q > R > S T. I: in R > S T gives only P > T, so II (P < T) does not follow.
