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 beards are nails.
Some nails are rings.
All rings are pendants.
Conclusions:
I. All rings can never be nails.
II. Some beards are rings.
III. Some nails are pendants.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Only conclusion III follows.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. All rings can never be nails → False (It is possible, but no definite conclusion can be drawn.)
II. Some beards are rings → False (It is possible, but no definite conclusion can be drawn.)
III. Some nails are pendants → True (As some nails are rings, and all rings are pendants, so, some nails are pendants is also true.)
Hence, Only conclusion III follows.
