Statements: J # Q, Q * D, D % P, P $ Y

Conclusions:       I. Q * Y                II. P *Y                III. Y @ P              IV. P # Q

A Only II is true Correct Answer Incorrect Answer
B If either conclusion II or III is true Correct Answer Incorrect Answer
C Only I is true Correct Answer Incorrect Answer
D If either conclusion I or II is true. Correct Answer Incorrect Answer
E None of these Correct Answer Incorrect Answer

Solution

given statements:  J # Q, Q * D, D % P, P $ Y After converting: J ≤ Q , Q > D, D < P , P ≥ Y After combining: J ≤ Q > D < P ≥ Y Conclusion a → Q * Y → Q > Y ( Q > D < P ≥ Y ) , No relationship can be established between Q and Y so, it is not true. Conclusion b → P * Y → P > Y ( P ≥ Y) it will make an either case, and conclusion III also is true.    Conclusion d → P # Q → P ≤ Q ( Q > D < P ), No relationship can be established between P and Q so, it is not true.
