Two statements are given, followed by two conclusions numbered I and II. 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:
Some pens are markers.
All markers are crayons.
Conclusions:
I. All pens can never be crayons.
II. At least some crayons are pens.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 1 i.e. Only conclusion II follows.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. All pens can never be crayons → False (It is possible, but no definite conclusion can be drawn.)
II. At least some crayons are pens → True (Since some pens are markers, and all markers are colours, so, at least some crayons are markers is also true.)
Hence, Only conclusion II follows.
