Statements: R © K, K * N, N $ J, J % H

Conclusions:      I.R $ N                   II.J @ K                                III.H @ N             IV.K $ H

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

Solution

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