Statement: My umbrella is black. Conclusions: I. All umbrellas are black. II. Some black things are umbrellas.
A. Neither I nor II follows
B. Only I follows
C. Only II follows
D. Both I and II follow
Answer: Option C
Solution (By JKSSB Mock Tests)
I does not follow from a single case. II follows because if my umbrella is black, then there exists at least one black thing that is an umbrella, so 'some black things are umbrellas' is true.
Statements:
1. Some papers are files.
2. Some files are folders.
Conclusions:
I. Some papers are folders.
II. All folders are papers.
Which conclusion(s) logically follow?
Explanation:
A 'some' relationship does not chain logically. There is no direct link established between papers and folders. Therefore, neither conclusion can be logically deduced.
Statement: He is a strict vegetarian; he doesn't even eat eggs. Conclusions: I. He avoids all animal products. II. He will not eat a cake that contains egg.
Explanation:
The additional information 'doesn't even eat eggs' implies he is pure vegetarian, so I follows (eggs are animal product). II: if cake contains egg, he won't eat it. Both follow.
