Question 33

In the following question below are given some statements followed by some conclusions based on those statements. Taking the 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 conclusion logically follows the given statements.
Statements:
I. All A are K.
II. Some J are K.
Conclusions:
I. Some A are J.
II. No K is J.
III. All K are J.

Solution

Conclusion 1: Some A are J - Not always true. Some A can be J but need not always be, as in above diagram.

Conclusion 2: No K is J - Since some J are K, converse is also true. i.e. some K are also J. Therefore the conclusion is false.

Conclusion 3: All K are J - As per the condition and as represented in the diagram, all K need not be J.

Thus, neither conclusion follows.

Option D is correct.
