    Statements: M $ K; K & N, N % R, R @ W

    Conclusions:     

    I. W & K               

    II. K & W              

    III. M % R

    A If only conclusion I is true Correct Answer Incorrect Answer
    B If only conclusion II is true Correct Answer Incorrect Answer
    C If only conclusion III is true Correct Answer Incorrect Answer
    D If neither conclusion a nor II nor III is true Correct Answer Incorrect Answer
    E If both conclusions I and II are true Correct Answer Incorrect Answer

    Solution

    given statements: M $ K; K & N, N % R, R @ W After converting: M ≥ K, K > N, N ≤ R, R < W After combining: M ≥ K > N ≤ R < W Conclusion a → W & K → W > K There is no relation between W and K in the statement M ≥ K > N ≤ R < W so, it is not true. Conclusion b → K & W → K > W There is no relation between K and W in the statement M ≥ K > N ≤ R < W. So, it is not true. Conclusion c → M % R   → M ≤ R There is no relation between M and R in the statement M ≥ K > N ≤ R < W. So, it is not true.
