CAT Mini Mock Test - 7 - Question 1

Instructions
Read the passage carefully and answer the questions given
. . . “Everybody pretty much agrees that the relationship between elephants and people has dramatically changed,” [says psychologist Gay] Bradshaw. . . . “Where for centuries humans and elephants lived in relatively peaceful coexistence, there is now hostility and violence. Now, I use the term ‘violence’ because of the intentionality associated with it, both in the aggression of humans and, at times, the recently observed behavior of elephants.” . . .
Typically, elephant researchers have cited, as a cause of aggression, the high levels of testosterone in newly matured male elephants or the competition for land and resources between elephants and humans. But. . . Bradshaw and several colleagues argue. . . that today’s elephant populations are suffering from a form of chronic stress, a kind of species-wide trauma. Decades of poaching and culling and habitat loss, they claim, have so disrupted the intricate web of familial and societal relations by which young elephants have traditionally been raised in the wild, and by which established elephant herds are governed, that what we are now witnessing is nothing less than a precipitous collapse of elephant culture. . . .
Elephants, when left to their own devices, are profoundly social creatures. . . . Young elephants are raised within an extended, multitiered network of doting female caregivers that includes the birth mother, grandmothers, aunts and friends. These relations are maintained over a life span as long as 70 years. Studies of established herds have shown that young elephants stay within 15 feet of their mothers for nearly all of their first eight years of life, after which young females are socialized into the matriarchal network, while young males go off for a time into an all-male social group before coming back into the fold as mature adults. . . .
This fabric of elephant society, Bradshaw and her colleagues [demonstrate], ha[s] effectively been frayed by years of habitat loss and poaching, along with systematic culling by government agencies to control elephant numbers and translocations of herds to different habitats. . . . As a result of such social upheaval, calves are now being born to and raised by ever younger and inexperienced mothers. Young orphaned elephants, meanwhile, that have witnessed the death of a parent at the hands of poachers are coming of age in the absence of the support system that defines traditional elephant life. “The loss of elephant elders,” [says] Bradshaw . . . "and the traumatic experience of witnessing the massacres of their family, impairs normal brain and behavior development in young elephants.” What Bradshaw and her colleagues describe would seem to be an extreme form of anthropocentric conjecture if the evidence that they’ve compiled from various elephant researchers. . . weren’t so compelling. The elephants of decimated herds, especially orphans who’ve watched the death of their parents and elders from poaching and culling, exhibit behavior typically associated with post-traumatic stress disorder and other trauma-related disorders in humans: abnormal startle response, unpredictable asocial behavior, inattentive mothering and hyperaggression. . . . [According to Bradshaw], “Elephants are suffering and behaving in the same ways that we recognize in ourselves as a result of violence. . . . Except perhaps for a few specific features, brain organization and early development of elephants and humans are extremely similar.”
Q. Which of the following statements best expresses the overall argument of this passage?

Detailed Solution for CAT Mini Mock Test - 7 - Question 1

Through the passage, the author explains how the ways elephants behave is similar to the trauma related response evoked in individuals. He explains how the elephant society is affected by the human activity and the impact of the same on the brain development of young elephants.
The primary purpose of the passage is not to draw an analogy between elephants and humans in any way. Therefore, we can eliminate options A and D. Option C states that the relationship between elephants and humans has changed from one of coexistence to one of hostility. Though this point is true, it is not the central theme of the passage. The author places much emphasis on how the elephant behaviour can be explained as a species-wide trauma response and hence, option B is the right answer.

Q. In paragraph 4, the phrase, “The fabric of elephant society . . . has[s] effectively been frayed by . . .” is:

Detailed Solution for CAT Mini Mock Test - 7 - Question 2

The author uses strong comparison in the given line. The author has not mentioned that the elephant society, which is like a fabric, is frayed by human activities. He uses the term 'the fabric of elephant society' and this comparison is called a metaphor.
We can eliminate option A since it fails to capture the fact that a comparison has been used.
Option D states that the line is an ode to the fragility of elephant society today. Option D fails to capture the fact that human activities are wrecking the social structure of elephants.
Option C states that the line is an exaggeration to bolster Bradshaw's claims. The author is not exaggerating the facts to substantiate Bradshaw's claims. He tries to capture the effects of human activities on the elephant society metaphorically. Therefore, option B is the right answer.

Q. The passage makes all of the following claims EXCEPT:

Detailed Solution for CAT Mini Mock Test - 7 - Question 3

The author explains how elephants are profoundly social creatures like humans and how human activities are putting elephants under stress. Then, he explains how the recent elephant behaviour is similar to post traumatic stress syndrome observed in humans. Options A, B, and C can be inferred.
The author expresses apprehension that young calves are raised by inexperienced elephant mothers and this, in turn, affects the brain development of the calves. Nowhere has it been mentioned that elephant mothers are developing newer ways of rearing their calves. Therefore, option D is the right answer.

CAT Mini Mock Test - 7 - Question 4

Instructions
Read the passage carefully and answer the questions given
. . . “Everybody pretty much agrees that the relationship between elephants and people has dramatically changed,” [says psychologist Gay] Bradshaw. . . . “Where for centuries humans and elephants lived in relatively peaceful coexistence, there is now hostility and violence.

[According to Bradshaw], “Elephants are suffering and behaving in the same ways that we recognize in ourselves as a result of violence. . . . Except perhaps for a few specific features, brain organization and early development of elephants and humans are extremely similar.”
Q. In the first paragraph, Bradshaw uses the term “violence” to describe the recent change in the humanelephant relationship because, according to him:

Detailed Solution for CAT Mini Mock Test - 7 - Question 4

In the first paragraph of the passage, the author uses the line "Now, I use the term ‘violence’ because of the intentionality associated with it". Therefore, we can infer that the author specifically uses the term violence to emphasize that the actions of the elephants on humans are deliberate just like those of humans on elephants.
Therefore, option B is the right answer.

CAT Mini Mock Test - 7 - Question 5

According to the passage, Said’s book, “Orientalism”:

Detailed Solution for CAT Mini Mock Test - 7 - Question 5

This is a slightly challenging question. To find the right answer, we have to read the entire second paragraph. The author towards the end says “Said’s work became a model for demonstrating cultural forms of imperialism in travel texts... legitimating discourses such as those articulated through travel writing” ...to legitimise something means to give approval to something or justify something.  Thus choice 2 is the right option, without a shade of doubt. Option 4 goes out because colonial domination and cultural imperialism seem to be one and the same thing. For the other choices we don’t see any significant evidence.

CAT Mini Mock Test - 7 - Question 6

From the passage, it can be inferred that scholars argue that Victorian women experienced self-development through their travels because: 

Detailed Solution for CAT Mini Mock Test - 7 - Question 6

This question is specifically about how Victorian women experienced self-development through their travels. The answer to this question can be found in the last few sentences of the last paragraph. The second last sentence of the last paragraph says that “...many studies demonstrated the ways in which women’s gendered identities were negotiated differently “at home” than they were “away”, thereby showing women’s self-development through travel. Thus without the slightest doubt we can mark 1 as the right choice

CAT Mini Mock Test - 7 - Question 7

American travel literature of the 1920s:

Detailed Solution for CAT Mini Mock Test - 7 - Question 7

This is a slightly tricky question. There are a few close choices, but by elimination we can arrive at the right choice. We have to answer for American literature of the 1920s. Option 1 goes out because it did not develop the desire for male protagonist’s desire for independence. Instead it expressed their sense of independence they experienced through travel. Thus instead of developing the desire, it celebrated the freedom that travel gives, making choice 3 the right answer. There is no reference for discovering a sense of identity different from others. Option 4 goes out because though there was emphasis on value of rural folk traditions, it doesn’t mean that they participated in it. They could have appreciated the value of rural folk traditions simply by observing those traditions from a distance or by indirectly studying about them. Choice 4 is not as directly stated as option 3 is

CAT Mini Mock Test - 7 - Question 8

From the passage, we can infer that feminist scholars’ understanding of the experiences of Victorian women travellers is influenced by all of the following EXCEPT scholars':

Detailed Solution for CAT Mini Mock Test - 7 - Question 8

This is a challenging question and demands careful reading of the last paragraph. The question wants us to pick a choice that would not have influenced feminist scholars' understanding of the experiences of Victorian women. Choice 1 goes out because what is given in the choice did influence. The passage says “from a liberal feminist perspective...”, suggesting that there was a liberal perspective brought in by the feminists. Remember we have to mark for the choice that did not influence the feminists. Option 3 goes out because gender issues can be derived from the fact that there were ideological constructs that posited men as explorers and women tied to home. So there were gender issues. Thus 3 can be ruled out. The fact that “poststructural turn in studies of Victorian travel writing has focussed attention on women’s diverse and fragmented identities”, suggests that feminists were aware of the ways in which identity was formed. Without being aware of that they would not be able to understand the gendered identities of Victorian women. For option 2 we have the least amount of evidence. The Victorian women were indeed tied to their class, but that doesn’t mean that the feminists had knowledge of class tensions in Victorian society

CAT Mini Mock Test - 7 - Question 9

Direction: The sentences given in the question, when properly sequenced, form a coherent paragraph. Each sentence is labeled with a letter. Choose the most logical order of sentences from the given choices to construct a coherent paragraph.

A. Patrilineal ownership of lands and the culture of dowry attached to it have turned daughters into bad debts.

B. The control of such castes on local politics aggravates masculine hubris.

C. The bigotry of our village culture and polity is intrinsically linked to a control of land and agriculture.

D. Land makes certain castes ‘kingly’ in rural communities.

Detailed Solution for CAT Mini Mock Test - 7 - Question 9

Sentence C talks of the intolerance that marks the village culture and polity. We see that this is the main idea of the paragraph.

Sentence D talks of some castes being considered “kingly"? in rural communities. Sentence C talks of the control of “these castes"? on local politics and how it aggravates masculine pride. So C comes after D. Both of these sentences substantiate the idea of bigotry that is made by sentence C.

Sentence A talks of the patrilineal system of passing ownership of lands and system of linking dowry to land ownership turning daughters to be regarded as “bad debts"?. This sentence substantiates the point make by sentence C.

The question is " Arrange the sentences in the correct order "
The order is CDBA

Hence, the answer is CDBA
Choice C is the correct answer.

CAT Mini Mock Test - 7 - Question 10

Which of the following four sentence is grammatically correct?

Detailed Solution for CAT Mini Mock Test - 7 - Question 10

The correct option is B. All other options have subject verb disagreement. The state of his affairs is the main subject which is singular. The correct usage would be "The state of affairs was/is such" which is only mentioned in B.

Seven candidates, Akil, Balaram, Chitra, Divya, Erina, Fatima, and Ganeshan, were invited to interview for a position.
Candidates were required to reach the venue before 8 am. Immediately upon arrival, they were sent to one of three interview rooms: 101, 102, and 103. The following venue log shows the arrival times for these candidates. Some of the names have not been recorded in the log and have been marked as ‘?’.

Additionally here are some statements from the candidates: Balaram: I was the third person to enter Room 101.
Chitra: I was the last person to enter the room I was allotted to.
Erina: I was the only person in the room I was allotted to.
Fatima: Three people including Akhil were already in the room that I was allotted to when I entered it.
Ganeshan : I was one among the two candidates allotted to Room 102.
Q. What best can be said about the room to which Divya was allotted?

Detailed Solution for CAT Mini Mock Test - 7 - Question 11

It is given that there were a total of 3 rooms and seven candidates. Ganeshan said that he was one among the two candidates allotted to Room 102 whereas Erina said that she is the only person in the room she was allotted to.
Therefore, we can say that there were 1 and 4 candidates in either 101 or 103 room. But it is given that Balaram was the third person to enter in the Room 101 therefore we can say that there were 4 candidates in Room 101 and only 1 candidate in room 103.

Fatima said that three people including Akhil were already in the room that I was allotted to when I entered it. Hence, we can say that Fatima was the last person to enter in 101 and Akhil is the first person who entered in room 101.
Chitra said that she was the last person to enter the room she was allotted to. Hence, we can say that Chitra was allotted room no 102 and she entered after Ganeshan.
Erina was the only person in room no 103.

Every element of S1 is made greater than or equal to every element of S2 by adding to each element of S1 an integer x. Then, x cannot be less than:

Detailed Solution for CAT Mini Mock Test - 7 - Question 20

The smallest integer of the series is 1 and greatest integer is 50. If each element of S1 is made greater of equal to every element of S2, then the smallest element 1 should be added to (50 - 1) = 49. Hence option (G-L) is the correct answer.

As this is a variable based question: the word "ANY" can be used.

Let the series of integers a1,a2,.......,a50 be 1,2,3,4,5,.......,50.

S1=1,2,3,4,.........24, S2=25,26,27,..........50.

CAT Mini Mock Test - 7 - Question 22

If the work done by p men in (p + 2) days is to the work done by (p + 4) men in (p – 1) days is in the ratio 1 : 1, then the value of p is:

Detailed Solution for CAT Mini Mock Test - 7 - Question 22

Work done will be directly proportional to number of men and days.
So according to the question:

  • [(p)(p + 2)] / [(p + 4)(p - 1)] = 1/1 
  • p2 + 2p /  p2 + 4p - p - 4 = 1
  • p2 + 2p =  p2 + 3p - 4
  • -p = -4
  • p = 4

CAT Mini Mock Test - 7 - Question 24

There is 80% increase in an amount in 8 years at simple interest. What will be the compound interest of Rs. 14,000 after 3 years at the same rate? 

Detailed Solution for CAT Mini Mock Test - 7 - Question 24

Simple interest = P * r * t /100, where, P is the Principal, r is the rate of interest and t is the time period such that the rate of interest and the time period have mutually compatible units like r % per annum and t years.

Here, in the first case, let the Principal be Rs.P and rate of interest be r % per annum. Time period is given as 8 years . Interest is given as 80 P / 100
So, 80 P / 100 = P * r * 8 / 100
Or, 80 = 8 r
So, r = 10 % per annum.

Now, in the second case, Principal is given as Rs. 14,000, rate of compound interest is 10 % per annum as determined above; and t is 3 years.
Compound interest = P * ( 1 + r/100)t - P 
= 14,000 * ( 1+ 10 /100)3 - 14,000
= 14,000 * ( 1 + 0.1)3 - 14,000
= 14,000 *(1.1)3 - 14,000
(14,000 * 1.331) - 14,000
= 18,634 - 14,000 = 4,634
So, the compound interest on Rs.14,000 at the same rate of interest as in case 1 in 3 years will be Rs. 4,634.

CAT Mini Mock Test - 7 - Question 25

A and B walk around a circular track. A and B walk at a speed of 2 rounds per hour and 3 rounds per hour respectively. If they start at 8 a.m. from the same point in opposite directions, how many times shall they cross each other before 9.30 a.m.?

Detailed Solution for CAT Mini Mock Test - 7 - Question 25

Relative speed = Speed of A + Speed of B = 2 + 3 = 5 rounds per hour
(∴ they walk in opposite directions)

⇒ They cross each other 5 times in 1 hour and 2 times in 1/2 hour

∵ Time duration from 8 a.m. to 9.30 a.m. = 1.5 hour

∴ They cross each other 7 times before 9.30 a.m

CAT Mini Mock Test - 7 - Question 26

Detailed Solution for CAT Mini Mock Test - 7 - Question 26

Given:

√(3 - 2x) + √(7 + 2x) = 4

Find the possible values of x.

Solution:

Step 1: Square both sides to eliminate the square roots:

(√(3 - 2x) + √(7 + 2x))² = 4²

⇒ (3 - 2x) + (7 + 2x) + 2√((3 - 2x)(7 + 2x)) = 16

⇒ 3 - 2x + 7 + 2x + 2√((3 - 2x)(7 + 2x)) = 16

⇒ 10 + 2√((3 - 2x)(7 + 2x)) = 16

⇒ 2√((3 - 2x)(7 + 2x)) = 6

⇒ √((3 - 2x)(7 + 2x)) = 3

Step 2: Square both sides again to remove the square root:

((3 - 2x)(7 + 2x)) = 9

Step 3: Expand the left side:

(3)(7) + (3)(2x) - (2x)(7) - (2x)(2x) = 9

21 + 6x - 14x - 4x² = 9

21 - 8x - 4x² = 9

Step 4: Bring all terms to one side:

21 - 8x - 4x² - 9 = 0

12 - 8x - 4x² = 0

Divide entire equation by -4 for simplicity:

-3 + 2x + x² = 0

Or, rearranged:

x² + 2x - 3 = 0

Step 5: Factor the quadratic equation:

(x + 3)(x - 1) = 0

Step 6: Find roots:

x = -3 or x = 1

Step 7: Verify these values satisfy the original equation:

  • For x = -3:

    √(3 - 2(-3)) + √(7 + 2(-3)) = √(3 + 6) + √(7 - 6) = √9 + √1 = 3 + 1 = 4 ✓

  • For x = 1:

    √(3 - 2(1)) + √(7 + 2(1)) = √(3 - 2) + √(7 + 2) = √1 + √9 = 1 + 3 = 4 ✓

Hence, the possible values of x are -3 and 1.

Answer: A. -3, 1

Two types of tea, A and B, are mixed and then sold at Rs. 40 per kg. The profit is 10% if A and B are mixed in the ratio 3 : 2, and 5% if this ratio is 2 : 3. The cost prices, per kg, of A and B are in the ratio

Detailed Solution for CAT Mini Mock Test - 7 - Question 27

The selling price of the mixture is Rs.40/kg.
Let a be the price of 1 kg of tea A in the mixture and b be the price per kg of tea B.
It has been given that the profit is 10% if the 2 varieties are mixed in the ratio 3:2
Let the cost price of the mixture be x.
It has been given that 1.1x = 40
x = 40/1.1
Price per kg of the mixture in ratio 3:2 = 

3.3a + 2.2b = 200 --- (1)
The profit is 5% if the 2 varieties are mixed in the ratio 2:3.
Price per kg of the mixture in ratio 2:3 = 

2.1a+ 3.15b = 200 -- (2)
Equating (1) and (2), we get,
3.3a+2.2b = 2.1a + 3.15b
1.2a = 0.95b

Detailed Solution for CAT Mini Mock Test - 7 - Question 28

L.C.M. of 21, 36, 66 = 2772.

Now, 2772 = 2 x 2 x 3 x 3 x 7 x 11

To make it a perfect square, it must be multiplied by 7 x 11.

So, required number = 22 x 32 x 72 x 112 = 213444

CAT Mini Mock Test - 7 - Question 29

A train is traveling at 48 kmph . It crosses another train having half of its length , traveling in opposite direction at 42 kmph, in 12 seconds. It also passes a railway platform in 45 seconds. What is the length of the platform?

Detailed Solution for CAT Mini Mock Test - 7 - Question 29

► Let the length of the train traveling at 48 kmph be 2x meters. 

► And length of the platform is y meters.

► Relative speed of train = (48+42) kmph

= (90*5/18) = 25 m/sec;

And 48 kmph = 48*5/18 = 40/3 m/sec.

 

► According to the question,

(2x +x)/25 = 12;

Or, 3x = 12*25 = 300;

Or, x = 300/3 = 100m 

► Then, length of the train = 2x = 100*2 = 200m.

200+y/(40/3) = 45;

600+3y = 40*45;

Or, 3y = 1800-600 = 1200;

Or, y = 1200/3 = 400 m.

► Length of the platform = 400 m.
