You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusion logically follows from the given statements, disregarding commonly known facts. Give answer :

    Statements: All numbers are alphabets. All

    alphabets are vowel. No vowel is digit. Conclusions:I. No number is digit. II. No alphabet is digit.
    A if only conclusion I follows. Correct Answer Incorrect Answer
    B if only conclusion II follows. Correct Answer Incorrect Answer
    C if either conclusion I or II follows. Correct Answer Incorrect Answer
    D if neither conclusion I nor II follows. Correct Answer Incorrect Answer
    E if both conclusions I and II follow. Correct Answer Incorrect Answer
