Three Statements are given followed by three conclusions numbered I, II, and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
All D are V.
Some S are D.
No W is a S.
Conclusions:
I. Some W are not D.
II. Some V are S.
III. Some D are S.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. Both Conclusions II and III follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some W are not D → False (No direct relation can be drawn.)
II. Some V are S → True (As all D are V, and some S is D, so, some V are S is also true.)
III. Some D are S → True (As some S are D, so, some D are S is also true.)
Hence, Both Conclusions II and III follow.
