Statements: M * T, D % T, D # K, K $ R

Conclusions: I. M * D      II. T # K                                III. K * M              IV. R @ T

A Only I is true Correct Answer Incorrect Answer
B Only II and III is true Correct Answer Incorrect Answer
C Only IV is true Correct Answer Incorrect Answer
D Only III is true. Correct Answer Incorrect Answer
E None of these Correct Answer Incorrect Answer

Solution

given statements:  M * T, D % T, D # K, K $ R After converting: M > T, D < T, D ≤ K, K ≥ R After combining: M > T > D ≤ K ≥ R Conclusion a → M * D → M > D ( M > T > D) , it is true. Conclusion b → T # K → T ≤ K ( T > D ≤ K) No relationship can be established between T and K so, it is not true. Conclusion c → K * M → K > M ( M > T > D ≤ K ) , No relationship can be established between K and M so, it is not true. Conclusion d → R @ T → R = T ( T > D ≤ K ≥ R), No relationship can be established between R and T so, it is not true.
