Statements: E & F, H # I, G $ F, E % D, G @ H

Conclusions:     I . D $ F                  II. F @ I                 III. I & G

A If only conclusion I is true Correct Answer Incorrect Answer
B If both conclusions I and II are true Correct Answer Incorrect Answer
C If both conclusions II and III are true Correct Answer Incorrect Answer
D If only II is true Correct Answer Incorrect Answer
E If both conclusions I and III are true Correct Answer Incorrect Answer

Solution

given statements: E & F, H # I, G $ F, E % D, G @ H After converting: E > F, H = I, G ≥ F, E ≤ D, G < H After combining: D ≥ E > F ≤ G < H = I Conclusion a → D $ F → D ≥ F: D ≥ E and E > F → D > F so It is not true. Conclusion b → F @ I → F < I: F ≤ G, G < H and H = I → F < I so, it is true.    Conclusion c → I & G → I > G:  I = H, and H > G → I > G so, it is true.
