In a certain code, ‘X $ Y’ means X is either smaller than or equal to Y; ‘X % Y’ means X is greater than Y; ‘X & Y’ means X is smaller than Y; ‘X # Y’ means X is either greater than or equal to Y; ‘X @ Y’ means X is equal to Y. Statements: Q & R, R $ U, U $ S, S & T. Conclusions: I. Q & S II. R % Q. Which of the conclusions is definitely true?
Correct answer D. Both conclusions I and II are true
Explanation
Decoding gives Q < R ≤ U ≤ S < T. I: Q < R ≤ U ≤ S gives Q < S, so I is true. II: Q Q, so II is true.
