    Statements:

    All Helpers are Maids.

    All Maids are Workers.

    Some Helpers are Supervisors.

    Conclusion:

    I. Some Maids are Supervisors.

    II. Some Workers are Supervisors.

    III. Some Supervisors are not Workers.

    A Only conclusions I and II follow Correct Answer Incorrect Answer
    B All the conclusions follow Correct Answer Incorrect Answer
    C Only conclusions I and III follow Correct Answer Incorrect Answer
    D Only conclusion III follows Correct Answer Incorrect Answer

    Solution

    Some Helpers are Supervisors (I) → Conversion → Some Supervisors are Helpers (I) + All Helpers are Maids (A) → Some Supervisors are Maids (I) → Conversion → Some Maids are Supervisors (I). Hence conclusion I follows Some Helpers are Supervisors (I) → Conversion → Some Supervisors are Helpers (I) + All Helpers are Maids (A) → Some Supervisors are Maids (I) + All Maids are Workers (A) → Some Supervisors are Workers (I) → Conversion → Some Workers are Supervisors (I). Hence conclusion II follows but conclusion III does not follow.
