CAT Mini Mock Test - 3 - Question 1

Direction: Read the following passage and answer the question that follows:
In the heart of the Amazon rainforest, a botanical enigma has piqued the interest of scientists and environmentalists alike. This enigma is the "Devil's Garden," a peculiar patch of land where only one species of tree, Duroia hirsuta, seems to thrive, while all others are conspicuously absent. For years, this anomaly baffled researchers, prompting theories ranging from soil peculiarities to indigenous farming practices. However, recent studies have shed light on a rather astonishing interplay between nature's flora and fauna.
Upon closer examination, scientists discovered that the Duroia hirsuta tree has an unlikely ally: the Myrmelachista schumanni ant. These ants form a mutualistic relationship with the tree, wherein the tree provides nectar from its stems, which is not found in any other species in the area. In return, the ants protect the tree from encroaching plant species by deploying a potent herbicide secreted from their bodies, effectively creating a botanical monoculture around their home.
The discovery of this relationship has profound implications for our understanding of mutualism and its impact on biodiversity. It raises the question of whether human intervention in preserving biodiversity should take into account such complex natural relationships, which can sometimes lead to the dominance of a single species over others in a given area. This phenomenon also highlights the delicate balance ecosystems maintain, which can be easily disrupted by external factors.
The "Devil's Garden" serves as a microcosm of the larger issues facing our planet's biodiversity. As the world grapples with environmental changes and human encroachment, the survival of such unique and intricate ecosystems hangs in the balance. It reminds us that nature's workings are far more complex and interconnected than they appear, and preserving biodiversity requires a deep understanding of these relationships.

Q. What is the primary focus of the passage?

Detailed Solution for CAT Mini Mock Test - 3 - Question 1

The passage primarily discusses the symbiotic relationship between the Duroia hirsuta tree and Myrmelachista schumanni ants, making option B the correct answer.

CAT Mini Mock Test - 3 - Question 5

Directions: Read the following passage carefully and answer the given question.

The psychiatrist, psychoanalyst and 'anti psychiatrist' Thomas Szasz argued that there was no such thing as mental illness. He believed that mental illnesses were 'problems of living': personal conflicts, bad habits and moral faults. Therefore, mental illness was the sufferer's own personal responsibility. As a consequence, Szasz claimed that psychiatry should be abolished as a medical discipline, since it had nothing to treat. If a person's symptoms had a physiological basis, then they were physical disorders of the brain rather than 'mental' ones.

I personally believe that mental illnesses are mental only in that they are psychiatric. Ordinary understandings of the mind, and what is and isn't part of it, have nothing to do with it. Perception is generally considered to be mental, a part of the mind – yet, while medicine considers deafness and blindness to be disorders of perception, it doesn't class them as mental illnesses. Why? The answer is obvious: because psychiatrists generally aren't the best doctors to treat deafness and blindness.

When people talk about 'the mind' and 'the mental' in psychiatry, my first thought is always 'What exactly do they mean?' A 'mental' illness is just an illness that psychiatry is equipped to deal with. That's determined as much by practical considerations about the skills psychiatrists have to offer, as it is by theoretical or philosophical factors. But this pragmatic approach hides itself behind appeals to 'mental illness'. In many contexts, the term mental tends to bring along inappropriate and stigmatizing connotations – showing that the wrong bridges have been built.

Imagine that you suffer from long-term, chronic pain. You go to the latest in a series of doctors: by this point, and especially if you are a member of a marginalized group (a woman or person of color, say), doctors might have dismissed or disbelieved you; they might have assumed you were exaggerating your pain, or perhaps that you were a hypochondriac. After some tests, and some questions, you're eventually told that your chronic pain is a mental illness, and referred to a psychiatrist. The psychiatrist, you are told, will not prescribe drugs or surgery, but will instead prescribe psychotherapy, also known as 'talk therapy', and occasionally, 'mental therapy'.

You might, quite reasonably, think that this doctor disbelieves you too. Perhaps they think that you have a delusion, or that you're lying because of some kind of personality disorder? In mainstream pieces on the topic, being referred to a psychiatrist is seen as tantamount to being disbelieved, dismissed or called a hypochondriac. It's understandable that you might be annoyed for your condition to be branded a 'mental illness'. But what about your doctor – what did they want you to take away from that interaction? It might well be that they absolutely believed that you were in severe, involuntary pain, caused by heightened sensitisation of the peripheral nervous system as a result of 'rewiring'. Pain that results from rewiring of the nervous system is known as 'neoplastic pain', recognised as a highly medically significant category of pain. They don't necessarily think you're lying or delusional. In invoking 'mental illness', what they might have meant is only that it might be best treated by talk therapy, and best managed and understood by a psychiatrist.

Q. Which of the following can be best inferred about Thomas Szasz terming mental illnesses as 'problems of living'?

Detailed Solution for CAT Mini Mock Test - 3 - Question 5

(1) - This cannot be inferred. In fact, Szasz completely ignores presence of any mental illness. According to him, what our personal conflicts lead to are simply 'problems' instead of 'illnesses'.
(2) - This can be inferred. According to Szasz, what people experience are daily problems, but they are made to look like mental illnesses, where otherwise no such thing exists.
(3) - This cannot be inferred. Again, Szasz does not believe in mental illnesses. Hence, even if an individual continues to experience distressing situations, 'mental illnesses' cannot exist.
(4) - No such view is inferable. Whether it is a result of personal or non personal experience, in no case can it be termed mental illness.

Q. In the statement 'mental illnesses are mental only in that they are psychiatric', what is the author trying to imply?

Detailed Solution for CAT Mini Mock Test - 3 - Question 6

(1) - This cannot be inferred. Although a problem to be dealt by psychiatrist does fall under the ambit of mental illness, it cannot be assumed that other doctors would be incapable of doing so.
(2) - Here, the success of treatment is not under discussion. The psychiatrist may/may not be successful. However, just because he was deemed capable of treating a problem makes it a mental problem.
(3) - This is what the author is implying. Mental problem is mental because it is dealt by a 'psychiatrist'. It has nothing to do with what actually constitutes a mental problem, rather the simple fact that it is treatable by a psychiatrist makes it a mental problem.
(4) - This cannot be inferred. Again, no comparison between abilities of other doctors and psychiatrists to solve mental problems is mentioned or inferable.

Q. Which of the following, in context of the passage, would justify terming an illness as 'mental illness'?

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

The author is of the opinion that mental illnesses are not necessarily related to the 'mind'. In fact, an illness can be termed as 'mental' if it is solely or sufficiently capable to be treated by a psychiatrist. Even problems related to factors considered mental, like 'perception', may not be termed mental illnesses if they are not sufficiently treatable by psychiatrists. For example: deafness etc. On the other hand, even physiological pains can be termed mental if they are better treated by psychiatrists.
Option 1 - accurately details this phenomenon.
Option 2 - This adopts a narrow view and fails to answer the question.
Option 3 - This cannot be inferred. It fails to justify naming an illness as mental illness.
Option 4 - Nothing about 'treatment' aspect can be inferred from the statement.

Q. Which of the following statements is the author most likely to disagree with?

Detailed Solution for CAT Mini Mock Test - 3 - Question 8

(1) - This is what the author means. He does not contest the mental illnesses. Rather, he contests when a particular illness is indeed a mental illness. It may be that such illness may not be present, but as it can be treated by a psychiatrist, it is indeed a mental illness.
(2) - This can be inferred from, 'Perception is generally considered . . . deafness and blindness,' in the 2nd paragraph.
(3) - This can be inferred. The passage indicates that people want that doctors should indeed regard their illness as mental irrespective of the stigmatizing conditions.
(4) - This cannot be inferred and is far fetched as it incorrectly assumes the basis for doctors not recommending an illness as mental.

CAT Mini Mock Test - 3 - Question 9

Directions: The passage given below is followed by four alternative summaries. Choose the option that best captures the essence of the passage.

It is important to examine the attitudes towards women before divulging into the roles in which they existed. While the overall religious and societal context of late antiquity has been discussed, the societal perception of the concept of womanhood or femininity ought to be discussed in its own right. One ought to look for sentiments regarding women held throughout the empire by investigating their portrayal in various historian accounts as well as ecclesiastical writings.

Detailed Solution for CAT Mini Mock Test - 3 - Question 9

The passage is stressing upon the need to analyse perception towards women before debating what roles they played. It will give us a general idea about them and also how different religions viewed them.
(1) - 'More important' is neither mentioned nor inferable. 'A simple analysis of attitudes is needed' is what is mentioned rather than them playing a more important role than previously thought of.
(2) - This accurately captures the essence as evident from the explanation. 'Other aspect' refers to 'debating' about the roles in which they existed.
(3) - Again, no such comparison between documents and oral comments is either made or inferable.
(4) - No such comparison between the importance of analysing attitudes over analysis of the roles is being made. The author simply mentions that it is important to know about perceptions, rather than it being more important.

CAT Mini Mock Test - 3 - Question 10

Directions: The passage given below is followed by four alternative summaries. Choose the option that best captures the essence of the passage.

We seem to have something within us which is not entirely a property of this world. If we were entirely of a longing of this world, sunk in this material world and exhausted completely in the phenomena that are visible, it would be impossible for us to know that there is any kind of limitation at all. We would never be unhappy for any reason. Unhappiness of every kind, sorrow of any character is an indication that there is something in the human individual which is not satisfied with anything in this world, and this endowment, this impulse arising from the human being, cannot be considered as a property of this world because anything that is an integral part of this visible world only, this world which is limited so much, cannot raise this question. A thing that is involved in the world cannot raise a question about the world.

Detailed Solution for CAT Mini Mock Test - 3 - Question 10

1. Not true. It is not the "pleasures" that lack "divinity"; it is the "man" who lacks something in him that he feels unhappy about despite the pleasures.
2. Not true. It is not "dissatisfaction" but the lack of complete satisfaction.
3. True. Man remains unhappy not because of indulgences but in spite of them, he partakes in them, and still cannot be happy. This means he has something in him that cannot be made happy by the material or worldly things. Thus, it may be inferred that some part in him is unworldly.
4. Not true. The author has not mentioned anywhere that man longs for something out of this world.

CAT Mini Mock Test - 3 - Question 11

Which of the following is the ODD ONE OUT? [TITA]
1. The ancient Greek philosopher Aristotle taught that living a virtuous life was the key to happiness.
2. The Indian philosophy of Buddhism teaches that the path to happiness lies in the elimination of desire and the achievement of enlightenment.
3. The German philosopher Immanuel Kant believed that morality is based on reason and that we should always act in a way that treats others as ends in themselves.
4. The 17th-century French philosopher Rene Descartes is known for his famous statement "I think, therefore I am", which established the concept of mind-body dualism.
5. The Chinese philosopher Confucius emphasized the importance of social harmony and moral behavior in achieving happiness.


Detailed Solution for CAT Mini Mock Test - 3 - Question 11

Statement 4 is the odd one out because it is the only statement that does not talk about the achievement of happiness as a central concept in philosophy. Statement 1 talks about Aristotle's philosophy that a virtuous life leads to happiness, Statement 2 talks about the Buddhist philosophy that the elimination of desire and the achievement of enlightenment leads to happiness, Statement 3 talks about Kant's philosophy that morality based on reason leads to happiness, and Statement 5 talks about Confucius' philosophy that social harmony and moral behavior lead to happiness. On the other hand, Statement 4 is discussing the concept of mind-body dualism, which is not directly related to the attainment of happiness. Therefore, Statement 4 is the odd one out.

Detailed Solution for CAT Mini Mock Test - 3 - Question 15

CAT Mini Mock Test - 3 - Question 16

A person invests an amount of Rs. 50000 in company Y in 2023 for 1 year. After one year, from the total amount received, he bought a Television worth of Rs. 20000 and invested the remaining amount in company X for one year. Find the interest received by him from the investment.

Detailed Solution for CAT Mini Mock Test - 3 - Question 16

Given:

A person invests an amount of Rs. 50000 in company Y in 2023 for 1 year

He bought a Television worth of Rs. 20000 in the next year with the amount received

He invested the remaining amount in company X for one year

Concept Used:

Simple interest (SI) = (P × R × T)/100

Where, P = principal amount, R = rate of interest, and T = time of investment

Calculation:

Amount received after 1 year from Y = 50000 + (50000 × 8)/100 = Rs. 54000

Remaining amount after buying television = 54000 - 20000 = Rs. 34000

Interest received on Rs. 34000 in the next year from X = (34000 × 8)/100 = Rs. 2720

∴ The correct answer is option 3

CAT Mini Mock Test - 3 - Question 17

In 2024, an amount of 1 Lac is invested in company X for 1 year and after that the total amount received is invested in company Y for 1 year in 2025. Find the total amount received after these two years. (The interest rate of 2025 for Y is the same as 2024)

Detailed Solution for CAT Mini Mock Test - 3 - Question 17

Given:

In 2024, an amount of 1 Lac is invested in company X for 1 year 

The total amount received is invested in company Y for 1 year in 2025

The interest rate of 2025 for Y is the same as 2024

Concept Used:

Simple interest (SI) = (P × R × T)/100

Where, P = principal amount, R = rate of interest, and T = time of investment

Calculation:

Amount received from X in 1 year = 100000 + (100000 × 8)/100 = Rs. 108000

Amount received from Y in 2025 = 108000 + (108000 × 15)/100 = Rs. 124200

∴ The correct answer is option 2

CAT Mini Mock Test - 3 - Question 18

In 2023, a part of Rs. 45,000 is invested in company X and the rest was invested in company Y for 1 year. If the total interest received is Rs. 3100, then what was the amount invested in company X?

Detailed Solution for CAT Mini Mock Test - 3 - Question 18

Given:

In 2023, a part of Rs. 45,000 is invested in company X

The rest was invested in company Y for 1 year

The total interest received is Rs. 3100

Concept Used:

Simple interest (SI) = (P × R × T)/100

Where, P = principal amount, R = rate of interest, and T = time of investment

Calculation:

Let, Rs. a is invested in X and Rs. (45000 - a) is invested in Y

According to the question,

(6a/100) + (45000 - a) × 8/100 = 3100

⇒ 6a + 360000 - 8a = 310000

⇒ 2a = 50000

⇒ a = 25000

∴ The amount invested in X was Rs. 25000

CAT Mini Mock Test - 3 - Question 19

Two different amounts in the ratio 8 : 15 are invested in X and Y respectively in 2022. Then find the ratio of the amount received after 1 year for X to Y.

Detailed Solution for CAT Mini Mock Test - 3 - Question 19

Given:

Two different amounts in the ratio 8 : 15 are invested in X and Y respectively in 2022

Concept Used:

Simple interest (SI) = (P × R × T)/100

Where, P = principal amount, R = rate of interest, and T = time of investment

Calculation:

Let, the amount invested in X is = 8a, and in Y is = 15a in 2022

The amount received from X = 8a + (8a × 10)/100 = Rs. (88a/10)

The amount received from Y = 15a + (15a × 5)/100 = Rs. (63a/4)

The respective ratio of amount received from X and Y is

⇒ (88a/10) : (63a/4) = 176 : 315

∴ The correct answer is option 2

A person invested Rs. 12,500 in company X in the year 2020 for 1 year. If he had invested the same amount in company Y for one year in 2020, how much less amount would he earn than?

Detailed Solution for CAT Mini Mock Test - 3 - Question 20

Given:

A person invested Rs. 12,500 in company X in the year 2020 for 1 year

Concept Used:

Simple interest (SI) = (P × R × T)/100

Where, P = principal amount, R = rate of interest, and T = time of investment

Calculation:

The interest received from X = (12500 × 12)/100 = Rs. 1500

The interest received from Y = (12500 × 10)/100 = Rs. 1250

He would earn (1500 - 1250) = Rs. 250 less from Y than X

∴ The correct answer is option 2

Four bells ring simultaneously at starting and an interval of 6 sec, 12 sec, 15 sec and 20 sec respectively. How many times they ring together in 2 hours?

Detailed Solution for CAT Mini Mock Test - 3 - Question 21

GIVEN:

Bells ring together every LCM of their intervals (6, 12, 15, 20 s). LCM is 60 s (common multiple).

Step 1: Find LCM

  • Prime factors: 6=2×3, 12=2²×3, 15=3×5, 20=2²×5.

  • LCM = 2² × 3 × 5 = 60 s.

Step 2: Total time

  • 2 hours = 7200 s.

Step 3: Count rings

  • They ring together at t=0 and every 60 s up to 7200 s.

  • Intervals: 7200 / 60 = 120.

  • Total (including start): 120 + 1 = 121.

The answer is C: 121.

Quick Verification/Shortcut

LCM(6,12,15,20)=60 (quick: max powers 2²,3,5).
Rings = (total s / LCM) + 1 (include t=0).
(7200/60) +1=121.

CAT Mini Mock Test - 3 - Question 23

Directions for Question: A set of 10 pipes (set X) can fill 70% of a tank in 7 minutes. Another set of 5 pipes (set Y) fills 3/8 of the tank in 3 minutes. A third set of 8 pipes (set Z) can empty 5/10 of the tank in 10 minutes.

Q. If one pipe is added for set X and set Y and set Z ' s capacity is increased by 20% of its original value and all the taps are opened at 2.58 p.m., then at what time does the tank gets filled? (If if is initially empty).

Detailed Solution for CAT Mini Mock Test - 3 - Question 23
  1. Find per-pipe filling rates

    • Set X: 10 pipes fill 0.7 tank in 7 min ⇒ rate per pipe = 0.7⁄(7·10) = 0.01 tank/min

    • Set Y: 5 pipes fill 3/8 tank in 3 min ⇒ rate per pipe = (3/8)⁄(3·5) = 0.025 tank/min

  2. New filling rates after adding one pipe each

    • X: 11 pipes × 0.01 = 0.11 tank/min

    • Y: 6 pipes × 0.025 = 0.15 tank/min

  3. Set Z emptying rate increase

    • Original emptying: 8 pipes empty 0.5 tank in 10 min ⇒ total = 0.5⁄10 = 0.05 tank/min

    • +20% ⇒ 0.05×1.2 = 0.06 tank/min (outflow)

  4.  Net Filling Rate
    0.11 + 0.15 - 0.06 = 0.20 tank / min

  5. Time to fill 1 tank:
    1/0.20 min = 5 mins

  6. Completion time:
    Started at 2: 58 p.m + 5 mins = 3: 03 p.m 

CAT Mini Mock Test - 3 - Question 24

In a company, 20% of the employees work in the manufacturing department. If the total salary obtained by all the manufacturing employees is one-sixth of the total salary obtained by all the employees in the company, then the ratio of the average salary obtained by the manufacturing employees to the average salary obtained by the nonmanufacturing employees is

Detailed Solution for CAT Mini Mock Test - 3 - Question 24

Let the number of total employees in the company be 100x, and the total salary of all the employees be 100y.

It is given that 20% of the employees work in the manufacturing department, and the total salary obtained by all the manufacturing employees is one-sixth of the total salary obtained by all the employees in the company.

Hence, the total number of employees in the manufacturing department is 20x, and the total salary received by them is (100y/6)

Average salary in the manufacturing department = (100y/6*20x) = 5y/6x

Similarly, the total number of employees in the nonmanufacturing department is 80x, and the total salary received by them is (500y/6)

Hence, the average salary in the nonmanufacturing department = (500y/6*80x) = 25y/24x

Hence, the ratio is:- (5y/6x): (25y/24x) 

=> 120: 150 = 4:5

The correct option is D

CAT Mini Mock Test - 3 - Question 25

The average height of 22 toddlers increases by 2 inches when two of them leave this group. If the average height of these two toddlers is one-third the average height of the original 22, then the average height, in inches, of the remaining 20 toddlers is

Detailed Solution for CAT Mini Mock Test - 3 - Question 25

Let the average height of 22 toddlers be 3x.
Sum of the height of 22 toddlers = 66x
Hence average height of the two toddlers who left the group = x
Sum of the height of the remaining 20 toddlers = 66x – 2x = 64x
Average height of the remaining 20 toddlers = 64x/20 = 3.2x
Difference = 0.2x = 2 inches => x = 10 inches
Hence average height of the remaining 20 toddlers = 3.2x = 32 inches

CAT Mini Mock Test - 3 - Question 26

It takes eight hours for a 600 km journey, if 120 km is done by train and the rest by car. It takes 20 minutes more, if 200 km is done by train and the rest by car. What is the ratio of the speed of the train to that of the car?

Detailed Solution for CAT Mini Mock Test - 3 - Question 26

Eight hours for a 600 km journey, when 120 km is done by train and 480 km by car.

It takes 20 minutes more if 200 km is done by train and 400 km by car.

Formula used:

Speed = Distance/Time

Calculation:

Let the speed of the train be x km/h

And the speed of the car be y km/h

⇒ 120/x + 480/y = 8

⇒ 120(1/x + 4/y) = 8

⇒ 1/x + 4/y = 1/15     ...i)

In the second condition

⇒ Total time = 8 + 20/60 = 25/3 hr

∴  200/x + 400/y = 25/3

⇒ 200(1/x + 2/y) = 25/3

⇒ 1/x + 2/y = 1/24     ...ii)

After solving equation (i) and (ii)

(By substracting equation 2 from equation 1)

⇒ x = 60 km/h

⇒ y = 80 km/h

Ratio of the speed of train and car is

⇒ 60 : 80

⇒ 3 : 4

∴ The ratio of the speed of train and car is 3 : 4.

CAT Mini Mock Test - 3 - Question 27

Find the value of x in the given figure.

Detailed Solution for CAT Mini Mock Test - 3 - Question 27

By the rule of tangents, we get:

⇒ 122 = (x + 7)x
⇒ 144 = x2 + 7x
⇒ x2 + 7x – 144 = 0
⇒ x2 +16x – 9x –144 = 0
⇒ x(x + 16) – 9(x + 16) = 0
⇒ x = 9 or –16

–16 can’t be the length, hence this value is discarded. Thus, x = 9

Detailed Solution for CAT Mini Mock Test - 3 - Question 28

Such questions are all about visualization and ability to write one area in terms of others.

Here, Let the radius of PQRS be 2r 
∴ Radius of each of the smaller circles = 2r/2 = r

Area A can be written as:
A = π (2r)2 – 4 x π(r)2 (Area of the four smaller circles) + B (since, B has been counted twice in the previous subtraction)

A = 4πr2 - 4πr2 + B
A = B
A/B = 1

Choice (B) is therefore, the correct answer.
Correct Answer: 1

⇒ (y - 3)(y + 6) ≥ 0

⇒ y ≥ 3 and y ≤ - 6

CAT Mini Mock Test - 3 - Question 30

How many 3 digit numbers can be formed from the digits 2, 3, 5, 6, 7 and 9 which are divisible by 5 and none of the digits is repeated? 

Detailed Solution for CAT Mini Mock Test - 3 - Question 30

Since each desired number is divisible by 5, so we must have 5 at the unit place. So, there is 1 way of doing it.
The tens place can now be filled by any of the remaining 5 digits (2, 3, 6, 7, 9). So, there are 5 ways of filling the tens place.
The hundreds place can now be filled by any of the remaining 4 digits. So, there are 4 ways of filling it.
∴ Required number of numbers = (1 x 5 x 4) = 20.
