Which of the following makes C $ E or Y % E definitely true?

A X © Y $ C @ D % E # G Correct Answer Incorrect Answer
B X # Y % C $ D @ E # G Correct Answer Incorrect Answer
C X # Y © C % D % E $ G Correct Answer Incorrect Answer
D X @ Y % C © D # E @ G Correct Answer Incorrect Answer
E None of these Correct Answer Incorrect Answer

Solution

a - X © Y $ C @ D % E # G → X = Y ≥ C > D ≤ E < G, in this C $ E = C ≥ E and Y % E = Y ≤ E, it is not true. b - X # Y % C $ D @ E # G → X < Y ≤ C ≥ D > E < G, in this C $ E = C ≥ E not follows and Y % E = Y ≤ E, not follows. c - X # Y © C % D % E $ G → X < Y = C ≤ D ≤ E ≥ G, in this C $ E = C ≥ E, not follows and Y % E = Y ≤ E, follows. d- X @ Y % C © D # E @ G → X > Y ≤ C = D < E > G, in this C $ E = C ≥ E, not follows and Y % E = Y ≤ E, not follows.
