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:
All girls are smart.
All smart are intelligent.
Conclusions:
I. All girls are intelligent.
II. Some girls are not intelligent.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Only conclusion I follows.
The least possible diagram is shown below:
Conclusions:
I. All girls are intelligent → Follow (This conclusion follows as all girls are smart and all smart are intelligent so, this definitely mean all girls are intelligent.)
II. Some girls are not intelligent → Does not follow (This conclusion does not follow as all girls are intelligent so it is not possible that some girls are not intelligent.)
Hence, Only conclusion I follows is the correct answer.
