CAT Miscellaneous Questions

Consider A: Some sphinxes laugh. No cowboy laughs => Some sphinxes are definitely not cowboys.

So, it will be either option a) or c).

Consider D: All crazy people are whistlers. Some crazy people are pianists. So, the crazy people who are pianists are also whistlers => Some whistlers are pianists.

So, option c) is the correct answer.

Options C and D are the correct ones as shown in the Venn Diagrams below.

Only B is the correct option. That can be explained from the Venn Diagram below:

In A, there need not be an intersection between earthquakes and landslides.

In B, the curios that are glass things are transparent. So, some curios are transparent. So, B is correct.

A)

All IIMs are in India. For IIMs to be BIMs, at least some BIMs must be in India. But they are not according to the second part of the sentence. Hence, No IIMs are BIMS => Third part can be inferred => A is true

B)

All IIMs are in India. For BIMs to be IIMs, at least some BIMs must be in India. But they are not according to the second part of the sentence. Hence, No BIMs are IIMs.

C and D cannot be inferred as there is a possibility that no IIMs are BIMs.

Of the given four options, only A is correct.

Note: If Rajiv dreamt about spiders, it doesn't necessarily mean that he used the internet. But if he didn't dream about spiders, he didn't use the internet.

If A => B, then ~B => ~A

Using this logic, we can say that:

A says that all software companies employ knowledge workers.

C says that Tara tech is a software company.

So, we can say that Tara Tech employs knowledge workers.

Option A: Traffic congestion and increase in carbon monoxide are hazardous to health. But, we cannot infer that one is a result of other. Hence, option A is wrong.

Option B: Option B is wrong because the traffic congestion that does not cause increased carbon monoxide might cause some thing else that is hazardous to health.

Option C: C and D are not related. So, we cannot infer E.

Option D: Increase in Carbon monoxide is hazardous to health and traffic congestion increases Carbon monoxide. So, we can say that traffic congestion is hazardous to health.

Option A: All sweets are tasty and no apple is tasty

=> Apples and sweets are disjoint sets.

Option a) is incorrect. Ram need not necessarily be a popular actor.

Option b) is also incorrect. The first two statements talk about actors whereas the third statement talks about people. So, it cannot be deduced.

Option c) is also incorrect. The first two statements talk about Ram whereas the third statement talks about all actors. So, it cannot be deduced.

Option d) is the correct answer. The third statement can be deduced from the first two statements.

The statements can be understood by the Venn Diagram below.

Modern industry is technology driven ( Modern industry is a subset of technology driven)

BTI is a modern industry ( BTI is a subset of modern industry)

Hence, BTI is technology driven (BTI is a subset of technology driven.)

Since this holds, the statements are implied.

The relationship between Golmal Islanders, Blue colored people and some smart people is as shown in the diagram below.

Since some smart people and golmal islanders are non-intersecting sets,option B holds true.

The sentence Ram and Sita are in great demand is a conclusion that can be drawn from Ram and Sita are MBAs and MBAs are in great demand.

Either Sita is sick or she is careless => Sita is sick or she is careless.

The statement can be written as follows:

Ram eats a hamburger => Ram get a swollen nose

Ram did not get a swollen nose => Ram did not eat a hamburger

Option d) is the correct answer.

The members are either hostile or have no confidence.

Consider the pair of sentences CB.

C says the members have confidence in the management. So, they do not have 'no confidence' => The members should be hostile in nature, which is what statement B says. So, option b) is the correct answer.

The sentence can be written as follows:

Ram reads late into the night => His father beats him

Ram's father did not beat him => Ram did not read late into the night

Irresponsible parents did not shout => Children cavorted

So, AB follows from the statement.

Statement A: There need not be an intersection between the sets Xs and Ys.

Statement B: There need not be an intersection between the sets Sonas and Crazy.

Statement D: Third statement follows only from the second statement.

The third statement in C follows from its first two statements.

Option b) is the correct answer.

Statement A: Since all cycles are men and some iciles are cycles, it follows that some iciles are definitely men.

Statement B: Girls is a subset of Teeth. There is no intersection between the sets Teeth and Yellow. So, there is no intersection between the sets Girls and Yellow.

The third sentences in C and D need not necessarily follow from the respective first two statements. Option b) is the correct answer.

Statement A: No sun is not white => All Sun is white. So, Sun is a subset of white. All moon is sun => Moon is a subset of Sun. So moon is a subset of white.

In none of the other three statements do the third sentences follow from the respective first two statements.

Option a) is the correct answer.

In both A and C the third statement is logically concuded. The reasoning is if A = B, B = C then A = C.

Similarly T's = Square,  Square = Rectangle then T's = Rectangle.

Idiots = Bumblers, Bumblers = Fumble then Idiots = Fumble

Option A => ACB

Zens are Marutis and Marutis are fragile => Zens are fragile

Hence, option A is the answer.

Option A: AFE

Dogs sleep in the open and some open are not sheep. E need not follow these statements because there is a possibility that all dogs sleep in open that are sheep.

All indoors are sheep and dogs are like sheep. Statement A is unrelated to this. Hence, option B is wrong.

Option C: ABE
A and B contain 4 sets => Not related. Hence, E cannot be inferred.

Either Sam is ill, or he is drunk.

So, we can say "if Sam is not drunk then he is ill" and "if Sam is not ill, then he is drunk".

(a) is incorrect as it doesn't have the "the more..., the more..." pattern in the sentence.

(c) is incorrect as it doesn't introduce the pronoun "they" even though it is used twice in the sentence.

(d) is inappropriate as it makes the sentence redundant by not conveying any new information.

It's haunting images is the correct answer. The haunting images doesn't make it clear as to how haunting images are related to the movie. Haunted means something to do with a ghost.
