Question

In these questions, there are two statements followed by three conclusions numbered, I, II and III. You have to take the given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusion logically follows from the given statements.

Statements
All nets are jets.
All jets are sets.

Conclusions
I. All jets are nets.
II. Some sets are neither nets nor jets.
III. No set is a net.

• A. Only III follows
• B. Only I follows
• C. Only II follows
• D. None follow

Answer 1

The correct option is D None follow

All nets are ets. [A-type]
All jets are sets. [E-type]
$A-A\Rightarrow A$ type
Conclusion: All nets are sets.
This conclusion is not given.
The conversion of A type is I type.
No conclusion can be negative.
Therefore, no conclusion follows.
