Three Statements are given followed by two conclusions numbered I and I. 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 I: All reptiles are amphibians.
Statement II: Some amphibians are frogs.
Statement III: Some frogs are turtles.
Conclusion I: Some amphibians are not reptiles.
Conclusion II: Some turtles are amphibians.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Neither conclusion I nor II follows.
The least possible Venn diagram is as follows:
Conclusion I: Some amphibians are not reptiles. - Does not follow (because All reptiles are amphibians given. So, Some amphibians are not reptiles it is not possible)
Conclusion II: Some turtles are amphibians. - Does not follow (because there is no direct relation between turtles and amphibians so it can be possible but not definite)
