Statements: 1. Some pens are not pencils. 2. All pencils are markers. Conclusions: I. Some pens are not markers. II. Some markers are pencils. Which conclusion(s) logically follow? MCQ with Answer and Explanation
Statements:
1. Some pens are not pencils.
2. All pencils are markers.
Conclusions:
I. Some pens are not markers.
II. Some markers are pencils.
Which conclusion(s) logically follow?
A. Only conclusion I follows
B. Neither I nor II follows
C. Only conclusion II follows
D. Both I and II follow
Answer: Option C
Solution (By JKSSB Mock Tests)
Even if some pens are not pencils, those pens could still be markers (because the marker category is larger than the pencil category). Thus, I does not follow. Since all pencils are markers, some markers are definitely pencils (II follows).
Statement: Since inequality is built in, wherever there is development there is little that can be done to arrest it except at the cost of development itself.
Conclusions:
I. To achieve development, inequality should be allowed to continue.
II. Equality and development do not go together.
Explanation:
Both conclusions follow from the statement. If arresting inequality comes at the cost of development, then to achieve development, inequality must be allowed (I). Also, it implies equality and development are not compatible (II).
Statements:
1. Some phones are smart.
2. No smart thing is cheap.
Conclusions:
I. Some phones are not cheap.
II. No phone is cheap.
Which conclusion(s) logically follow?
Explanation:
The phones that are smart cannot be cheap (since no smart thing is cheap). Therefore, at least some phones are definitely not cheap (Conclusion I). We don't know about the phones that are not smart, so II does not follow.
