Statement: All that glitters is not gold. Conclusions: I. Some things that glitter are gold. II. Gold always glitters.
A. Both I and II follow
B. Neither I nor II follows
C. Only I follows
D. Only II follows
Answer: Option B
Solution (By JKExamLibrary)
The statement means not everything that glitters is gold; it doesn't say that some things that glitter are gold (they could be none). II is false because gold may not always glitter. Neither follows.
Statement:
The price of petrol has increased globally; hence, inflation in the country will rise.
Conclusions:
I. Petrol prices directly impact inflation in the country.
II. The country imports petrol from the global market.
Which conclusion(s) logically follow?
Explanation:
The statement draws a direct cause-and-effect link between global petrol prices and domestic inflation, making Conclusion I valid. Furthermore, this link implies the country's economy is tied to global petrol prices, which logically implies it imports or relies on global petrol (Conclusion II).
Statement: By 2005 to achieve 70% literacy, a new scheme has been started on 2/5/2001.
Conclusions:
I. On 2/5/2001 literacy is less than 70%.
II. This new scheme would be completed by 2005.
Explanation:
Neither conclusion follows. The statement sets a target to achieve 70% literacy by 2005, but the current literacy rate is not explicitly stated (it could already be 70% or higher, aiming to maintain). Conclusion II is not stated; the scheme started on that date, but its completion date is not mentioned.
Statement: This medicine is effective only if taken with warm water. Conclusions: I. Taking with cold water reduces its effect. II. It cures all diseases.
