    In the question below there are four statements followed by three conclusions I, II and III. You have to take the four given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follow from the four statements disregarding commonly known facts.

    Statements: Only a few Rayon is Cotton. No

    Cotton is Muslin. Only a few Muslin is Modal. All Modal are Silk. Conclusions: I. Some Silk can be Muslin. II. Some Modal are not Rayon. III. All Muslin can be Rayon.
    A Only conclusion I follows Correct Answer Incorrect Answer
    B Only conclusion I and conclusion II follow Correct Answer Incorrect Answer
    C Only conclusion II follows Correct Answer Incorrect Answer
    D None of the above conclusions follow Correct Answer Incorrect Answer
    E Only conclusion III follows Correct Answer Incorrect Answer

    Solution

    Some Muslin is Modal (I) + All Modal is Silk (A) → Some Muslin are Silk (I) → Conversion → Some Silk are Muslin (I). Hence conclusion I does not follow. Some Rayon are Cotton (I) + No Cotton is Muslin (E) → Some Rayon are Muslin (O) + Some Muslin are Modal (I) → No conclusion. Hence conclusion II does not follow. Some Rayon are Cotton (I) + No Cotton is Muslin (E) → Some Rayon are Muslin (O) → Probable conclusion → All Muslin can be Rayon (I). Hence conclusion III follows.
