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:
Some colours are rainbows.
Some paints are rainbows.
All rainbows are drawings.
Conclusions:
I. Some drawings are colours.
II. All paints are drawings.
III. Some drawings are rainbows.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Only conclusions I and III follow.
The least possible Venn diagram:
Conclusions:
I. Some drawings are colours → Follow (As, some colours are rainbows and all rainbows are drawings. So, some drawings are colours it is definitely true.)
II. All paints are drawings → Does not Follow (As, some paints are rainbows and all rainbows are drawings. So, it is possible but not definitely true)
III. Some drawings are rainbows → Follow (As, all rainbows are drawings. So, some drawings are rainbows it is definitely true.)
