UGC NET Paper 1: Held on 27th August 2024 Shift 1 (Previous Year Paper)

Given:

Revenue from Books in 2023 = ₹79 lakh

Total Revenue in 2023 = ₹40 + ₹54 + ₹79 = ₹173 lakh

Formula used:

Percentage from Books = (Revenue from Books / Total Revenue) × 100

Calculation:

⇒ Percentage from Books = (79 / 173) × 100

⇒ Percentage from Books ≈ 46%

∴ The approximate percentage of revenue from books in 2023 is 46%.

Given:

Total revenue in 2022 = ₹40 + ₹42 + ₹87 = ₹169 lakh

Total revenue in 2023 = ₹40 + ₹54 + ₹79 = ₹173 lakh

Formula used:

Revenue growth rate = ((Revenue in 2023 - Revenue in 2022) / Revenue in 2022) × 100

Calculation:

⇒ Revenue growth rate = ((173 - 169) / 169) × 100

⇒ Revenue growth rate ≈ 2.37%

Revenue in 2024 = Revenue in 2023 × (1 + Growth Rate)

⇒ Revenue in 2024 = 173 × (1 + 2.37 / 100)

⇒ Revenue in 2024 ≈ ₹177.095 lakh

∴ The approximate revenue in the year 2024 will be ₹177.095 lakh.

Given:

Revenue from Journals:

2020 = ₹45 lakh

2021 = ₹47 lakh

2022 = ₹40 lakh

2023 = ₹40 lakh

Formula used:

Change in Revenue = Revenue in current year - Revenue in previous year

Calculation:

For 2021:

⇒ Change = 47 - 45 = ₹2 lakh

For 2022:

⇒ Change = 40 - 47 = -₹7 lakh

For 2023:

⇒ Change = 40 - 40 = ₹0 lakh

∴ The highest change in revenue from the sale of journals occurred in 2022, with a decrease of ₹7 lakh compared to the previous year.

Given:

Revenue from Journals, Magazines, and Books:

2020: Journals = ₹45 lakh, Magazines = ₹35 lakh, Books = ₹70 lakh

2021: Journals = ₹47 lakh, Magazines = ₹40 lakh, Books = ₹80 lakh

2022: Journals = ₹40 lakh, Magazines = ₹42 lakh, Books = ₹87 lakh

2023: Journals = ₹40 lakh, Magazines = ₹54 lakh, Books = ₹79 lakh

Formula used:

Identify years where revenue increased in at least two types of publications.

Calculation:

From 2020 to 2021:

Journals: Increase (₹45 to ₹47)

Magazines: Increase (₹35 to ₹40)

Books: Increase (₹70 to ₹80)

⇒ Increase in all three types (At least two types increased)

From 2021 to 2022:

Journals: Decrease (₹47 to ₹40)

Magazines: Increase (₹40 to ₹42)

Books: Increase (₹80 to ₹87)

⇒ Increase in two types (Magazines and Books)

From 2022 to 2023:

Journals: No Change (₹40 to ₹40)

Magazines: Increase (₹42 to ₹54)

Books: Decrease (₹87 to ₹79)

⇒ Increase in only one type

∴ The number of years with an increase in revenue from at least two types of publications is 2 (2021 and 2022).

Given:

Total Revenue in 2020 = ₹150 lakh

Total Revenue in 2023 = ₹173 lakh

Formula used:

Percentage Increase = ((Revenue in 2023 - Revenue in 2020) / Revenue in 2020) × 100

Calculation:

⇒ Percentage Increase = ((173 - 150) / 150) × 100

⇒ Percentage Increase = (23 / 150) × 100 ≈ 15%

∴ The approximate increase in total revenue from 2020 to 2023 is 15%, so the correct answer is option (3).

The correct answer is - Data packets may follow different routes and may arrive at different times in different order.

Key Points

• Packet Switching
• Packet switching is a method of data transmission where messages are divided into smaller packets before being sent.
• Each packet can take a different path to the destination, leading to packets arriving at different times and potentially out of order.
• The destination device reassembles the packets in the correct order to recreate the original message.

Additional Information

• Option 2: Data packets will always follow the same route and arrive at the same time in the same order.
• This describes circuit switching, not packet switching. In circuit switching, a dedicated communication path is established for the duration of the transmission.
• Option 3: Data packets will always follow the same route but could arrive at different times in different order.
• Inconsistent with packet switching as packets do not follow a single predetermined path. This scenario is more aligned with circuit switching with potential delays.
• Option 4: Data packets may follow different routes but will always arrive at the same time in the same order.
• Packets arriving at the same time and in order is not typical of packet switching. Packet switching can result in varied arrival times and requires reordering at the destination.

The correct answer is - Vaişesika

Key Points

• Vaişesika
• The Vaişesika school of Classical Indian Philosophy was founded by the sage Kanada.
• It is known for its naturalistic approach and its theory of atomism.
• According to Vaişesika, the physical world is composed of indivisible particles called atoms (anu).
• These atoms combine in various ways to form the diversity of objects we perceive.
• Vaişesika also focuses on metaphysics and categorizes reality into six or seven categories (padarthas) including substance, quality, action, generality, particularity, and inherence.

Additional Information

• Advaita
• Advaita Vedanta is a school of Hindu philosophy and spiritual practice.
• Founded by Adi Shankaracharya, it posits non-dualism (Advaita) and asserts that the individual self (Atman) and the ultimate reality (Brahman) are one and the same.
• It emphasizes the illusory nature of the material world (Maya) and seeks liberation (Moksha) through knowledge (Jnana).
• Buddhists
• Buddhism, founded by Siddhartha Gautama (the Buddha), is based on the Four Noble Truths and the Eightfold Path.
• Buddhism does discuss elements akin to atomism in its Abhidharma texts, but its focus is more on impermanence (Anicca), suffering (Dukkha), and non-self (Anatta).
• It provides a psychological and ethical framework rather than a strictly physical or naturalistic one.
• Samkhya
• Samkhya is one of the oldest schools of Indian philosophy, traditionally attributed to sage Kapila.
• It is dualistic and posits two fundamental realities: Purusha (consciousness) and Prakriti (matter).
• Samkhya focuses on the enumeration and categorization of the components of the universe and the process of evolution from the unmanifest (Prakriti) to the manifest world.

The correct answer is - Quantitative

Key Points

Hence, "Option 3" is the correct answer.

The correct answer is - B, C and D Only

Key Points

• Sub-contrary Propositions
• Statement B: They cannot both be false
• This is true for sub-contrary propositions. In logic, sub-contrary propositions are pairs of propositions that cannot both be false simultaneously, but they can both be true.
• Statement C: If one is false, the other must be true
• This is also true for sub-contrary propositions. If one proposition is false, the other must be true to prevent both from being false simultaneously.
• Statement D: They can both be true
• This is true for sub-contrary propositions. They are not required to be mutually exclusive in terms of truth; both propositions can be true at the same time.

Additional Information

• Other Options Explained
• Statement A: If one is true, the other must be false
• This is not true for sub-contrary propositions. This characteristic is actually of contradictory propositions, not sub-contrary propositions. Sub-contrary propositions can both be true, which contradicts this statement.

The correct answer is - placebo group

Key Points

• Placebo Group
• A placebo group in medical research is a set of participants that receives a treatment which has no therapeutic effect.
• The placebo itself is designed to look like the actual treatment but does not contain any active ingredient that would affect the condition being studied.
• This group is used as a control to help determine the effectiveness of the actual treatment by comparing the outcomes between the two groups.
• The use of placebo groups helps to account for the placebo effect, where participants experience perceived or actual improvements in their condition simply because they believe they are receiving treatment.

Additional Information

• Experimental Group
• This group receives the treatment or intervention that is being tested in the study.
• Outcomes from this group are compared to those of the control or placebo group to determine the treatment's effectiveness.
• Control Group
• This group does not receive the experimental treatment but may receive a standard treatment or no treatment at all.
• It serves as a benchmark to measure how the experimental group performs relative to normal conditions.
• Independent Group
• In experimental design, this refers to a group of subjects that is not influenced by other groups or variables within the study.
• The term "independent group" is more commonly used in the context of statistical analysis to describe groups that are not related or paired.

Given:

Total value = ₹570

Denominations: ₹20, ₹10, ₹5, ₹2, ₹1

Number of coins of each denomination is the same

Formula used:

Total Value = Number of Coins × (Sum of Denominations)

Calculation:

Let the number of coins of each denomination be x.

Total Value = x × (20 + 10 + 5 + 2 + 1)

⇒ 570 = x × 38

⇒ x = 570 / 38

⇒ x = 15

∴ The correct answer is option 3.

The correct answer is - B and D Only

Key Points

• B and D Only
• Statement B: "No animals are trees" means that there is no overlap between the set of animals and the set of trees.
• Statement D: "No trees are animals" is another way of saying that the set of trees and the set of animals do not intersect.
• Both B and D are logically equivalent because they express the same relationship: the two sets are mutually exclusive.

Additional Information

• A. All non-trees are non-animals
• This statement means that if something is not a tree, then it is also not an animal. This does not directly mean that no animals are trees.
• C. Some animals are not trees
• This statement suggests that there are animals that are not trees, which is a weaker assertion compared to B and D. It does not imply mutual exclusivity between the sets.

The correct answer is - Recover

The correct answer is 'Decreasing snow cover and melting ice sheets result in reduced reflection of sunlight.'

Key Points

• Positive Feedback in Climate Change:
• Positive feedback in climate change refers to processes that amplify the initial warming. When certain changes in the climate system trigger mechanisms that further enhance warming, it is considered a positive feedback loop.
• The reduction in snow cover and melting ice sheets reduce the Earth's albedo (reflectivity). Since snow and ice reflect a significant portion of sunlight, their reduction means that less sunlight is reflected back into space and more is absorbed by the Earth's surface, leading to further warming.
• This process creates a cycle where warming causes ice to melt, which then leads to more warming.

Additional Information

• Other Options Explained:
• The warmer Earth radiates more infrared energy (heat) into space: This is a negative feedback mechanism because as the Earth warms, it emits more infrared radiation, which helps to cool the planet by sending heat into space.
• Plants remove carbon dioxide from the air: This process is known as carbon sequestration and is a negative feedback mechanism. Plants absorb carbon dioxide during photosynthesis, which helps to reduce the greenhouse gases in the atmosphere and mitigate warming.
• The oceans remove carbon dioxide from the air: The oceans act as a carbon sink, absorbing large amounts of carbon dioxide from the atmosphere. This is also a negative feedback mechanism as it helps to lower atmospheric carbon dioxide levels and reduce warming.

Given:

5 pumps work 18 hours/day to empty the tank in 12 days.

6 pumps need to empty the tank in 9 days.

Formula used:

Pumps × Hours/day × Days = Constant (Tank Capacity)

Calculation:

For 5 pumps:

⇒ 5 × 18 × 12 = Constant

⇒ Constant = 1080

For 6 pumps working for 9 days:

⇒ 6 × Hours/day × 9 = 1080

⇒ Hours/day = 1080 / (6 × 9)

⇒ Hours/day = 1080 / 54 = 20 hours

∴ The correct answer is option (2), 20 hours.

**The correct answer is "This is an illogical statement."**

**Key Points**

- **Illogical Statement:**
- The statement "A vessel has mass. Therefore, all parts of the vessel have mass." is illogical because it assumes that the property of the whole (having mass) necessarily applies to all parts of the whole without any supporting evidence.
- While it is true that the vessel as a whole has mass, it does not logically follow that every individual part of the vessel must have mass. For example, the vessel could contain hollow parts or components that do not contribute to the mass.
- This type of reasoning falls under the category of a logical fallacy, specifically the fallacy of division, where one assumes that something true for the whole must also be true for all its parts.

**Additional Information**

- **Inflection Errors:**
- Inflection errors pertain to mistakes in the modification of words to express different grammatical categories. The given statement does not contain such errors.
- **Flaw of Ambiguity:**
- An ambiguity flaw occurs when a statement can be interpreted in multiple ways. The given statement is not ambiguous; its meaning is clear and specific, though incorrect.
- **Uncritical Generalization:**
- Uncritical generalization involves making broad claims based on insufficient evidence. While the statement does generalize, its primary issue is the logical fallacy rather than being uncritically generalized.

Additional Information

• Financial success: The passage does not mention financial success as being easier to achieve in a ritual-oriented workplace.
• Stress and anxiety: The text indicates that a "religious observance workplace" reduces stress and anxiety, making it easier to maintain a state of flow, so this option is incorrect.
• Ambiguous goals: The passage mentions that religious rituals provide clear rules and goals, thus this option is incorrect.

The correct answer is: Option 2.

Key Points

• Explanation: The passage explains that in modern Japan, due to the influence of religions like Confucianism, Buddhism, and Shintoism, the process of doing a task (rituals, etiquette, work ethic) is emphasized over the end results in business practices.
• Specifically, it states: "In doing business in Japan, the process of doing a task, etiquette and work ethic are more important than the end results."
• In summary, option 2 accurately captures how religious rituals influence business practices in modern Japan, stressing the importance of civility and process over the end result, whereas options 1, 3, and 4 do not align with the details provided in the passage.

Additional Information

• Results are prioritized over process: This is incorrect as the passage clearly states that the process is prioritized over the end results in Japanese business practices.
• Religious observance is not important in Japanese culture: The passage explicitly mentions that religious observances are unusually pervasive in daily life and business practices in Japan, making this option incorrect.

The correct answer is: Option 2.

Key Points

• Explanation: The passage explains that when achieving a big goal, religious rituals help by giving us clear rules and breaking the goal down into smaller, manageable parts.
• This is highlighted in the sentence: "Rituals give us a process, steps on our way to achieving the goal. When it comes to achieving a big goal, try breaking the goal down into parts and then working on achieving each part."
• In summary, option 2 accurately articulates how religious rituals help in achieving a big goal by providing clear rules and breaking the goal into sub-steps, based on the explanations provided in the passage. Options 1, 3, and 4 are either inconsistent with the text or directly refuted by the passage.

Additional Information

• Religious rituals condition us to feel more stressed: The passage actually states that rituals help reduce stress, not increase it.
• Religious rituals eliminate the need for goals: The passage does not claim that rituals eliminate goals; rather, they provide a structured way to achieve them.
• Religious rituals enable us to ignore goals: Again, the passage indicates that rituals help us achieve our goals through a structured process, not ignore them.

The correct answer is: Option 2.

Key Points

• Explanation: The passage suggests that humans are naturally drawn to engaging religious observances.
• It highlights that in modern Japan, religious rituals are integrated into daily life and business practices, providing clear rules and goals that help people stay engaged and structured in their activities.
• This is evident from the lines: "Rituals give us clear rules and goals that help us enter a state of flow" and "Use your daily rituals as a tool to enter a state of flow and focus on enjoying your daily rituals."
• In summary, option 2 accurately reflects the role of religious rituals in human life as presented in the passage, which is to keep us busy and provide structure to our daily activities. Options 1, 3, and 4 either misinterpret the text or contradict the information provided in the passage.

Additional Information

• Distracts us from our goals: The passage specifically mentions that rituals help achieve goals by breaking them down into manageable parts, not by distracting from them.
• Are more important only during religious practices: The passage indicates that rituals are pervasive in daily life and business practices, not just during explicit religious practices.
• Irrelevant to contemporary life: The passage emphasizes the relevance of religious rituals in modern Japan, showing that they play a significant role in daily and business practices.
