In this question, 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 follows/follow from the statements.
Statements:
Some mirrors are glass.
All glass are taps.
Some taps are pens.
Conclusions:
I. Some glass are mirrors.
II. All taps are glass.
III. Some pens are taps.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Only conclusions I and III follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some glass are mirrors → True (As some mirrors are glass, so some glass is mirrors is also true.)
II. All taps are glass → False (It is possible, but no definite conclusion can be drawn.)
III. Some pens are taps → True (As some taps are pens, so some pens are taps is also true.)
