Question

    Read the given statements and conclusions carefully.

    Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements. Statements: Some Dog are Cat No Rat is Mouse All Rat Are Cat Conclusions: I. Some Cat are Mouse II. Some Rat are Dog III. No Cat is Mouse.
    A Only conclusion I follows. Correct Answer Incorrect Answer
    B Only conclusion III follows. Correct Answer Incorrect Answer
    C Only conclusion I and conclusion II follow Correct Answer Incorrect Answer
    D Either conclusion I or conclusion III follows and conclusion II doesn’t follow Correct Answer Incorrect Answer

    Solution

    No Rat is Mouse (E) → Conversion → No Mouse is Rat (E) + All Rat Are Cat (A) → Some Cat are not Mouse (O*). Hence neither conclusion I nor II follows bit it will make a complementary pair. Hence either conclusion I or II follows.
