    Statements: F % W, W © R, R @ M, M $ D

    Conclusions:   I.D @ R                                II.M $ F                                III.R @ D              IV.R * F In the following questions, the symbols @, © , %, $ and * are used with the following meaning as illustrated below.   ‘P © Q’ means ‘P is not smaller than Q’.   ‘P * Q’ means ‘P is not greater than Q’. ‘P @ Q’ means ‘P is neither greater than nor equal to Q’. ‘P $ Q’ means ‘P is neither smaller than nor equal to Q’. ‘P % Q’ means ‘P is neither greater than nor smaller than Q’.
    A Only I is true Correct Answer Incorrect Answer
    B Only IV is true Correct Answer Incorrect Answer
    C None 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:  F % W, W © R, R @ M, M $ D After converting: F =W, W ≥ R, R < M , M > D After combining: F = W ≥ R < M > D Conclusion a → D @ R → D < R ( R < M > D ) No relationship can be established between D and R so, it is not true. Conclusion b → M $ F → M > F ( F = W ≥ R < M ) No relationship can be established between M and F so, it is not true. Conclusion c → R @ D → R < D ( R < M > D ) No relationship can be established between D and R so, it is not true. Conclusion d → R * F → R ≤ F ( F = W ≥ R ), it is true.
