Question

    In the following questions, the symbols @, #, %, $ and * are used with the following meaning as illustrated below. A * B means A is either equal to or greater than B. A $ B means A is equal to B. A # B means A is either equal to or smaller than B. A & B means A is smaller than B. A @ B means A is greater than B.

    Statements:  P * R, M & N, R $ M

    Conclusions:      a) P @ M              b) P $ M

    A If only conclusion a is answer Correct Answer Incorrect Answer
    B If only conclusion b is answer Correct Answer Incorrect Answer
    C If either conclusion a or b is answer Correct Answer Incorrect Answer
    D If neither conclusion a nor b is answer Correct Answer Incorrect Answer
    E If both conclusions a and b are true Correct Answer Incorrect Answer

    Solution

    given statements: P * R, M & N, R $ M After converting: P ≥ R, M < N, R = M After combining: P ≥ R = M < N Conclusion a → P @ M → P > M The relation between P and M in the statement P ≥ R = M < N : P > M As the relation between P and M is P ≥ M . So, it can be true. Conclusion b → P $ M → P = M The relation between P and M in the statement P ≥ R = M < N : P ≥ M. So, it can be true.
