Statements:
1. Some cups are plates.
2. No plate is a spoon.
Conclusions:
I. Some cups are not spoons.
II. No cup is a spoon.
Which conclusion(s) logically follow?
A. Only conclusion II follows
B. Both I and II follow
C. Neither I nor II follows
D. Only conclusion I follows
Answer: Option D
Solution (By JKSSB Mock Tests)
Since some cups are plates, and no plates are spoons, the portion of cups that are plates can never be spoons. Thus, some cups are definitely not spoons (Conclusion I). However, we do not know about all cups, so we cannot definitively say no cup is a spoon (Conclusion II).
Statements:
1. Some glasses are mirrors.
2. All mirrors are fragile.
Conclusions:
I. Some fragile things are glasses.
II. All glasses are fragile.
Which conclusion(s) logically follow?
Explanation:
The glasses that are mirrors must also be fragile, meaning some fragile things are glasses (I follows). We do not know about the glasses that are not mirrors, so we cannot conclude they are all fragile (II does not follow).
Statement: Our approach of fund management is based on Science as much as on common sense and discipline because our goal is consistent performance in the long term- Advertisement of a mutual fund company.
Conclusions:
I. Only the approach of Science of investment can lead to high gains in short term investment.
II. It is not necessary to go for long term investment when low return short term investment is available.
Explanation:
Neither conclusion follows. The advertisement focuses on long-term consistent performance, not on short-term high gains through science alone. Conclusion II contradicts the company's emphasis on long-term investment.
