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 sixes are sevens.
No seven is an eight.
Conclusions:
I. All eights are sixes.
II. No eight is a six.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Neither conclusion I nor II follows
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. All eights are sixes → False (It is possible, but no definite conclusion can be drawn.)
II. No eight is a six → False (It is possible, but no definite conclusion can be drawn.)
Hence, the correct answer is Neither conclusion I nor II follows.
