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.
Statement:
No lotus is a daisy.
All lotuses are tulips.
All tulips are sunflowers.
Conclusions:
I. All daisies are tulips.
II. Some sunflowers are daisies.
III. No sunflower is a daisy.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Either conclusion II or III follows.
The least possible Venn diagram is as follows:
Conclusions:
I. All daisies are tulips. - Does not follow (because there is no direct relation between daisies and tulips)
II. Some sunflowers are daisies. - Does not follow (It is possible but not definite)
III. No sunflower is a daisy. - Does not follow (It is possible but not definite)
So, Either conclusion II or III follows.
