    Question

    Which of the following does not make J @ K and R # K

    definitely not true? In the following questions, the symbols @, #, %, $ and © are used with the following meaning as illustrated below: ‘A @ B’ means ‘A is neither smaller than nor equal to B’. ‘A # B’ means ‘A is neither greater than nor equal to B’. ‘A % B’ means ‘A is not greater than B’. ‘A $ B’ means ‘A is not smaller than B’. ‘A © B’ means ‘A is neither smaller than nor greater than B’.
    A J # Q % N © K $ T © U $ R Correct Answer Incorrect Answer
    B J $ Q @ N @ R # T © K % U Correct Answer Incorrect Answer
    C J @ Q © N $ K $ T @ U © R Correct Answer Incorrect Answer
    D J © Q @ N © K @ T $ U © R Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Explanation; a - J # Q % N © K $ T © U $ R → J < Q ≤ N = K ≥ T = U ≥ R, in this J @ K = J > K and R # K = R < K, it will hold the condition true. b - J $ Q @ N @ R # T © K % U → J ≥ Q > N > R < T = K ≤ U, in this J @ K = J > K, not follows and R # K = R < K, follows but it will not hold the condition true. c - J @ Q © N $ K $ T @ U © R → J > Q = N ≥ K ≥ T > U = R, in this J @ K = J > K, follows and R # K = R < K, follows but it will not hold the condition true. d- J © Q @ N © K @ T $ U © R → J = Q > N = K > T ≥ U = R, in this J @ K = J > K, follows and R # K = R < K, follows but it will not hold the condition true.
