Question

    In the questions given below, there are three

    statements followed by three conclusions I, II and III. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts. Statements: Some Technical are Mechanical All Mechanical are Electrical No Mechanical is Chemical Conclusion: I. No Technical is Chemical II. Some Electrical is not Chemical III. Some Technical is not Electrical
    A Only conclusion III follows Correct Answer Incorrect Answer
    B Only conclusion I follows Correct Answer Incorrect Answer
    C Only conclusions I and III follow Correct Answer Incorrect Answer
    D Only conclusion II follows Correct Answer Incorrect Answer
    E None of the conclusions follow Correct Answer Incorrect Answer

    Solution

    Some Technical are Mechanical (I) + No Mechanical is Chemical   (A) → Some Technical are not Mechanical (O). Hence conclusion I does not follow. No Mechanical is Chemical (E) → Conversion → No Chemical is Mechanical (E) + All Mechanical are Electrical (A) → Some Electrical is not Chemical (O). Hence conclusion II follows. Some Technical are Mechanical (I) + All Mechanical are Electrical (A) → Some Technical are Electrical (I). Hence conclusion III does not follow.
