Statements: R @ D, D $ J, J # M, M @ K Conclusions:      
I. K # J                  
II. D @ M           
III. R $ J               
IV. K @ D

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