Three statements are given followed by four conclusions numbered I, II, III and IV. 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 horses are camels.
Some mouses are camels.
All mouses are ants.
Conclusions:
I. No horses are ants.
II. Some ants are mouses.
III. Some ants are camels.
IV. No mouse is horse.
Show answer & explanation

Explanation
The correct answer is option 2 i.e. Only Conclusion II and III follow.
The least possible venn diagram is:
Conclusions:
I. No horses are ants. → Does not follow (As there is no direct relation between them)
II. Some ants are mouses.→ Follows (As all mouses are ants. So, definitely some ants are mouses.)
III. Some ants are camels. → Follows (As all mouses are ants and some mouses are camels. So, some ants are camels too)
IV. No mouse is horse. → Does not follow (As there is no direct relation between them)
