Answers & Solutions:

1) Answer (B)

From the figure below we can see that conclusion I is false. As the subset wireless is a subset of devices and overlaps with the set phones, the set devices must overlap with phones. Hence, some devices are phones.

2) Answer (A)

As musicians is a subset of music lovers and music lovers set and ‘people who like drums’ set does not overlap => musicians and ‘people who like drums’ set cannot overlap. Hence, conclusion I follows. From the figure below we can see that conclusion II is untrue.

3) Answer (D)

From the figure below we can see that both conclusions are false. Hence, option D.

4) Answer (E)

As some teachers are lawyers, by reversing the statement we get some lawyers are teachers. As all advocates are lawyers, some lawyers must be advocates. Hence, both conclusions necessarily follow.

5) Answer (B)

From the figure below we can see that conclusion I is false. As the set tools is a subset of set levers, and books and tools overlap, then books and levers must also overlap. Hence, some books are levers must be true.

6) Answer (D)

The figure below shows a case when both conclusions are untrue. Hence, option d.

7) Answer (D)

The figure below shows a case when both conclusions are not true. Hence, option D.

8) Answer (C)

In the figure on the left, we see that the conclusion I does not follow. In the figure on the right, we see that the conclusion II does not follow. However, both cases cannot exist at the same time. Either one or the other of the two conclusions must be true. Hence, option C.

9) Answer (C)

From the figure on the left we can see a case when conclusion I isn’t true. Hence, conclusion I does not follow. From the figure on the left we can see a case when conclusion II isn’t true. Hence, conclusion II does not follow. For I to be untrue, All hornets should be reptiles. Hence, the set hornets should be a subset of the set reptiles. Hence, the set hornets cannot overlap with the set birds. Hence, some birds will not be hornets. The cases shown below are mutually exclusive. If one occurs the other cannot occur and vice versa. Hence, either conclusion I or II follows.

10) Answer (B)

From figure on the left we can see that the conclusion is not true in the case shown. Hence conclusion 1 does not follow. From the figure on the right, we can see that we cannot draw the set reptiles to encase all bees as it cannot overlap with the set birds. Hence, some bees will not be reptiles. Hence, conclusion II follows.

11) Answer (D)

The data given to us:
Statements: Some mangoes are yellow. Some tixo are mangoes.

This can be intrepreted as:

Conclusions: A. Some mangoes are green which is a wrong conclusiom
B. Tixo is yellow which is again a wrong conclusion.
Neither I or II follow.

12) Answer (B)

The only statement which will be a fact is ‘Some baseball caps are blue’.
All baseball caps are hats. Hats are of two colours blue and black.
Therefore, some baseball caps are blue.
Hence, only statement II is true.
13) Answer (C)

14) Answer (E)

15) Answer (D)

16) Answer (B)

17) Answer (C)

18) Answer (B)

19) Answer (C)

From the diagram, we can see that All crows can be pigeons and All bats can be black.
Hence, option C is the correct answer.

20) Answer (E)

From the diagram, we can see that all batsmen being all rounder is a possibility and some wicket keepers can be all rounders.
Hence, option E is the correct answer.
