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:
No actor is an engineer.
All engineers are magicians.
Conclusions:
I. No magician is an engineer.
II. Some magicians are engineers.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Only conclusions II follows.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. No magician is an engineer → False (It is possible but no definite conclusion can be drawn).
II. Some magicians are engineers → True (As engineers are magicians, so, some magicians are engineers).
Hence, Only conclusions II follows.
