From the diagram, we can see that All pages can be notebooks and some books can be notebooks.
Hence, option C is the correct answer.

From the diagram, we can see that some desks can be chair and some class can be table.
Hence, option E is the correct answer.

The given statements can be expressed diagrammatically as follows without violating any condition.

As we can see, neither of the conclusions follow. Therefore, option D is the right answer.

From the diagram, we can see that some TVs can be ACs. Hence, conclusion I follows.
From the diagram, we can see that some heaters can be radios. Hence, conclusion II follows.
Therefore, option C is the correct answer.

From the venn diagram, we can see that conclusion I follows.

Some books are pens and no pen is a chalk. So, some books are definitely not chalks. Thus, all books cannot be chalks. So, conclusion II is not possible. Hence, option A is the correct answer.

The below Venn diagram shows a possibility.
From the venn diagram we can see that only conclusion II follows.

From the venn diagram we can see that only conclusion I follows.

From the venn diagram we see that only conclusion I follows.

Some Plants are not green as all yellow are not Green. And as we can see some Trees are Plants is a possibility. Hence, option B is correct.

The venn diagram for above statements isÂ :

Conclusion:

(I) Polynomials are quadratic = false
(II) Linear equations are quadratic = false

Thus, neither I nor II follows

=> Ans – (C)

Based on the statements given we can make following possibilities –

We cannot definitely say that conclusion I follow as other possibilities exist.
Conclusion II follows.
Hence, option B is right choice.

No actor is a producer. Some directors are producers.
The following diagram represents a possibility.

Directors, who are producers, cannot be actors. Therefore, some directors are not actors. Hence, conclusion I is definitely true.
Directors, who are not producers, can be actors. Therefore, we cannot say conclusion II to be definitely true. Therefore, only conclusion I follows. Hence, option A is the right answer.

We have following possibility as shown in the diagram:

Thus neither I nor II follows.
Hence, option C is the right answer.

The Venn diagram for the concerned syllogism is as follows. That explains the answer

The Venn diagram for the concerned syllogism is as follows. That explains the answer

The Venn diagram for the concerned syllogism is as follows. That explains the answer. Since the conclusions are complimentary, either of them is implied.

The Venn Diagram for the concerned statements is as follows. So, only conclusion 1 is implied.
