UGC NET Paper 1: Held on 12th Dec 2023 Shift 1 (Previous Year Paper)

Number of Registered Cars and Population Data:

 

Calculation Details

City A: Per capita registered cars = 9500 / 0.8 = 11875 cars per million people

City B: Per capita registered cars = 1500 / 0.2 = 7500 cars per million people

City C: Per capita registered cars = 10000 / 0.6 = 16666.67 cars per million people

City D: Per capita registered cars = 7400 / 0.75 = 9866.67 cars per million people

Hence, In the year 2020, per capita registered cars were maximum in the city: City C

Given:

Number of cars registered in 2017 = 7500

Number of cars registered in 2018 = 8000

Number of cars registered in 2019 = 9000

Number of cars registered in 2020 = 9500

Formula Used: 

Percentage growth = (Final value - Initial value) / Initial value × 100

Average growth percentage = Total percentage growth / Number of periods

Calculation:

Percentage growth of each year,

2017 - 2018 ⇒ (8000 - 7500) / 7500 × 100

⇒ 500 / 75 = 6.67%

2018 - 2019 ⇒ (9000 - 8000) / 8000 × 100

⇒ 1000 / 80 = 12.50%

2019 - 2020 ⇒ (9500 - 9000) / 9000 × 100

⇒ 500 / 90 = 5.56%

Now, calculate the average growth percentage,

⇒ (6.67 + 12.50 + 5.56) / 3 

⇒ 8.24

Use the average growth percentage to estimate the number of registered cars in 2021:

Estimated cars in 2021 = Final value in 2020 × (1 + Average growth percentage)

Estimated cars in 2021 = 9500 × (1 + 0.0824)

Estimated cars in 2021 = 9500 × 1.0824 ≈ 10,283

∴ The correct answer is 10,283.

Calculation:

Total number of cars registered in 2017 = A + B + C + D

⇒ (7500 + 1200 + 6000 + 5000) 

⇒ 19,700

Total number of cars registered in 2018 = A + B + C + D

⇒ (8000 + 1350 + 7500 + 6000)

⇒ 22,850

Required Percentage = (22850 - 19700) / 19700 × 100 

⇒ 3150 / 19700 × 100

⇒ 15.98 ≈ 16%

∴ The correct answer is 16%.

Calculation:

Total number of cars registered in 2020 = A + B + C + D

⇒ (9500 + 1500 + 10000 + 7400)

⇒ 28,400

Total number of cars registered in 2017 = A + B + C + D

⇒ (7500 + 1200 + 6000 + 5000) 

⇒ 19,700

Required ratio = 28,400 / 19,700

⇒ 28400 : 19700

⇒ 284 : 197

∴ The correct answer is 284 : 197.

Calculation:

Percentage growth from 2017 to 2020

In city A = (9500 - 7500) / 7500 × 100

⇒ 2000 / 7500 × 1000 = 26.66%

In city B = (1500 - 1200) / 1200 × 100

⇒ 300 / 1200 × 100 = 25%

In city C = (10000 - 6000) / 6000 × 100

⇒ 4000 / 6000 × 100 = 66.66%

In city D = (7400 - 5000) / 5000 × 100

⇒ 2400 / 5000 × 100 = 48%

City C has shown maximum percentage growth.

Hence, City C is the correct answer.

The correct response is User specific information.

Key Points

• The automation element of online media has significantly enhanced the generation and dissemination of user-specific information.
• Through algorithms and data analysis, online platforms can tailor content recommendations and advertisements based on user preferences, behavior, and demographics.
• This level of personalization allows users to access information that is more relevant and targeted to their interests and needs.

Additional Information

Limited quantity of quality information

This option is incorrect. The automation element of online media does not necessarily limit the quantity of quality information.

In fact, automation can facilitate the efficient processing and distribution of vast amounts of information, including high-quality content.

Complex philosophical information

This option is incorrect. While online media can certainly facilitate the dissemination of complex information, including philosophical discussions and ideas, the automation element primarily focuses on delivering personalized content rather than specifically generating complex philosophical information.

Non-specific general information  

• This option is incorrect. The automation element of online media aims to provide more specific and targeted information to users rather than non-specific general information.
• Through algorithms and user data analysis, online platforms strive to offer content that is relevant and personalized to individual users' preferences and interests.

The correct answer is 1) (A), (B) and (C) Only.

Key Points

• A) Denotation - Denotation refers to the literal or explicit meaning of a sign or symbol. It represents the basic, objective definition of the sign without any added interpretation or cultural context.
• (B) Connotation - Connotation refers to the subjective or cultural associations and meanings that are added to a sign beyond its denotative meaning. These associations can be personal, social, or cultural, and they contribute to the deeper interpretation and understanding of the sign.
• (C) Myth - In communication theory, myth refers to the broader cultural narratives, ideologies, and beliefs that shape how signs are interpreted and understood within a society. Myths provide the overarching framework through which individuals make sense of the world and assign meaning to signs and symbols.

Additional Information

(D) Credibility - Credibility is not typically considered an order of signification in communication theory. Instead, credibility relates to the perceived trustworthiness, expertise, and reliability of the source or message in communication. While credibility is important in influencing how messages are received and interpreted, it is not part of the orders of signification.

(E) Attribution - Attribution refers to the process of assigning causality or responsibility to a particular source or factor in communication. It involves determining the origins or reasons behind a message or event. Similar to credibility, attribution is not considered an order of signification but rather a concept related to understanding the context and impact of communication

The correct answer is: (A), (D) and (E) Only.

Key Points 

Positive teacher-student relationships are essential for creating a supportive and conducive learning environment. Let's analyze each option:

(A) A teacher who punishes students for asking questions - This is not an example of a positive teacher-student relationship. Punishing students for asking questions can discourage them from actively participating in class, inhibit their curiosity, and create a negative learning atmosphere.

(D) A teacher who humiliates his/her students - This is not an example of a positive teacher-student relationship. Humiliating students can damage their self-esteem, erode trust, and hinder their academic and personal development.

(E) A teacher who ignores the needs and concerns of his/her students - This is not an example of a positive teacher-student relationship. Ignoring the needs and concerns of students can make them feel undervalued, unimportant, and disconnected from the learning process.

Additional Information

• Positive teacher-student relationships have been linked to various positive outcomes, including improved academic performance, increased student engagement, enhanced motivation, and better socio-emotional development.

• Teachers play a critical role in fostering these relationships by creating a supportive, inclusive, and respectful learning environment where students feel valued, heard, and empowered to succeed.

• By prioritizing communication, respect, empathy, and encouragement, teachers can cultivate positive relationships that benefit both students and the overall learning community.

The correct answer is: Earth Summit

 Key Points

1. The Convention on Biological Diversity (CBD) was indeed opened for signature during the Earth Summit.
2. The Earth Summit, also known as the United Nations Conference on Environment and Development (UNCED), was held in Rio de Janeiro, Brazil, in June 1992.
3. During this summit, the CBD was one of the key agreements negotiated and adopted by participating nations.
4. The CBD aims to promote the conservation of biological diversity, the sustainable use of its components, and the fair and equitable sharing of benefits arising from genetic resources.

 Additional Information

• Montreal Protocol - This protocol is related to the protection of the ozone layer and the phase-out of ozone-depleting substances. It was adopted in 1987 and opened for signature in Montreal, Canada, hence the name. However, it is not associated with the Convention on Biological Diversity.
• Kyoto protocol - The Kyoto Protocol is an international treaty aimed at reducing greenhouse gas emissions and addressing climate change. It was adopted in Kyoto, Japan, in 1997, but it is not related to the Convention on Biological Diversity.
• Stockholm Convention - The Stockholm Convention on Persistent Organic Pollutants (POPs) is an international treaty aimed at eliminating or restricting the production and use of certain persistent organic pollutants that pose significant risks to human health and the environment. It was adopted in Stockholm, Sweden, in 2001. While important for environmental protection, it is not associated with the Convention on Biological Diversity.

 Important Points

• The Convention on Biological Diversity (CBD) is one of the major international agreements addressing environmental conservation and sustainability. It emphasizes the importance of biodiversity for ecological stability, human well-being, and sustainable development.
• The CBD has three main objectives: conservation of biodiversity, sustainable use of its components, and fair and equitable sharing of benefits arising from genetic resources. It has been ratified by numerous countries and plays a crucial role in global efforts to safeguard biodiversity and ecosystem services.

The correct answer is (B) and (D) Only.

Key Points 

To determine which p-values are significant at a 5% level of significance, we compare them to the significance level (α) of 0.05.

If the p-value is less than or equal to the significance level (p ≤ α), we reject the null hypothesis and consider the result statistically significant. Otherwise, if the p-value is greater than the significance level (p > α), we fail to reject the null hypothesis, and the result is not considered statistically significant.

Let's analyze each option:

(A) 0.5 - Not significant (p > α)

(B) 0.04 - Significant (p ≤ α)

(C) 0.95 - Not significant (p > α)

(D) 0.002 - Significant (p ≤ α)

(E) 0.995 - Not significant (p > α)

Based on the comparison with the significance level (α = 0.05), the significant p-values are (B) 0.04 and (D) 0.002.

Additional Information 

• In hypothesis testing, the p-value represents the probability of observing the data (or more extreme results) given that the null hypothesis is true.
• When conducting hypothesis tests for correlation coefficients, such as Pearson's correlation coefficient (r), a low p-value indicates strong evidence against the null hypothesis, suggesting that there is a statistically significant relationship between the variables being studied.
• In this context, obtaining a significant p-value (p ≤ α) at a 5% level of significance (α = 0.05) indicates that the correlation coefficient observed in the sample is unlikely to have occurred by random chance alone.
• Therefore, researchers can infer that there is a statistically significant correlation between the variables in the population from which the sample was drawn.
• Conversely, non-significant p-values (p > α) suggest that the observed correlation coefficient is not statistically significant at the chosen level of significance.
• In such cases, researchers fail to reject the null hypothesis, indicating that there is insufficient evidence to conclude a significant relationship between the variables based on the sample data.
• Understanding the significance of p-values in hypothesis testing is crucial for interpreting the results of statistical analyses and drawing valid conclusions about the relationships between variables in research studies.

The correct response is (B) and (D) Only.

Key Points 

In a negatively skewed distribution, the correct option is (B) and (D) only.

Here's a breakdown of why each option is true or false:

A) Mean > Mode: This is not necessarily true. In a negatively skewed distribution, the mean can be greater than, equal to, or less than the mode, depending on the specific data and the degree of skew.

B) Mean < Median: This is true in a negatively skewed distribution. The mean is pulled towards the long tail (left side) due to the presence of more extreme values on that side. This makes the mean fall to the left of the median, which is the "center" of the data.

C) Median < Mode: This is not necessarily true. As with option (A), the relationship between the median and mode can vary depending on the data.

D) Mode > Mean: This is true in some negatively skewed distributions, but not all. When the peak of the distribution is at a higher value than the mean, the mode will be greater than the mean. However, it's important to note that this is not always the case.

Here's a visual representation to help understand why B and D are true:

The correct response is A teacher assigns a group project and students work together to do research and present their findings.

Key Points

A teacher assigns a group project and students work together to do research and present their findings:

• This situation perfectly illustrates collaborative learning. Students are required to work together as a group, which necessitates communication, problem-solving, division of tasks, and collaboration to achieve a common goal.
• This enriches each student's learning experience through peer interactions, shared knowledge, and mutual support, all key features of collaborative learning.

 Additional Information

A teacher assigns individually a reading assignment and students take notes:

This scenario involves individual work where each student is working on their own without interaction with other students.

The essence of collaborative learning involves working together with others to enhance learning through group dynamics and mutual support.

Therefore, this option does not exemplify collaborative learning.

A teacher gives a lecture on a topic and students take notes individually:

Similar to option 1, this situation also involves individual learning rather than collaborative efforts.

Although students are learning the same material, there is no active collaboration or interactivity among them during the learning process in this scenario.

Thus, it is not an example of collaborative learning.

A teacher assigns homework for students to complete independently:

This option clearly specifies that the work is to be completed independently.

While independent work is crucial for developing individual skills and understanding, it does not involve the collective problem-solving, discussion, and peer interaction characteristic of collaborative learning.

Hence, this is not an example of collaborative learning.

The correct answer is - (D), (C), (A), (B).

The correct answer is - Indicator word test.

Key Points

• The indicator word test involves looking for certain words or phrases in the argument that typically signify whether the argument is deductive or inductive.
• In this case, the word "Hence" indicates a conclusion is being drawn directly from the premise provided.
• The argument structure here implies a form of logical necessity, where being a father (under traditional biological and gender assumptions) necessarily means being male.
• This linkage between the premise and the conclusion suggests a deductive structure, where the conclusion is purported to follow necessarily from the premise.

Additional InformationRigorous requirements testing:

• This involves examining the argument to see if it meets the rigorous standards for valid deductive reasoning or strong inductive reasoning.

Common pattern test:

• This test looks for patterns that arguments typically follow, such as those found in deductively valid argument forms (e.g., modus ponens, modus tollens) or common inductive patterns (e.g., generalizations from a sample, causal inferences).

Charitable principle test:

• This involves interpreting the argument in the most reasonable way possible, making allowances for informal or conversational context.

The correct answer is: Statement I is correct but Statement II is incorrect.

Key Points

Statement I: This statement is accurate.

• Breeder reactors are designed to produce more fissile material than they consume by converting fertile isotopes like uranium-238 into fissile plutonium-239.

Statement II: This statement is incorrect.

• As of 2023, the share of nuclear energy in India's energy mix is around 7%, while the share of renewable energy is around 12%. Therefore, renewable energy currently holds a larger share than nuclear energy.

Additional InformationNuclear energy:

• Nuclear energy is the energy released during nuclear fission or fusion, particularly when used to generate electricity.
• Nuclear Fission: Involves splitting atoms (usually uranium or plutonium) to release energy.
• Nuclear Fusion: Combines atoms (usually isotopes of hydrogen) under high pressure and temperature to release energy; not yet commercially viable.
• Key Advantages:
• Low Carbon Emissions: Produces minimal greenhouse gases compared to fossil fuels.
• High Energy Density: Far more efficient than fossil fuels; a small amount of nuclear fuel can produce a large amount of energy.
• Reliable: Provides a consistent power output, not dependent on weather or climate.

Given:

Rate of interest = 10% per annum

Time = 2 years

Calculation:

Let the principle amount be P.

First we will calculate the simple interest of 2 years,

⇒ S.I. = (P × R × T)/100

⇒ (P × 10 × 2)/100

⇒ 0.2P

Now, we will calculate the compound interest of 2 years,

⇒ C.I. = A - P

⇒ P(1 + r)^t - P

⇒ P((1 + 0.1)² - 1)

⇒ P((1.1)² - 1²)

⇒ P(1.1 + 1)(1.1 - 1)

⇒ P(2.1)(0.1)

⇒ 0.21P

Now it is given that the difference is Rs. 5431

⇒ 0.21P - 0.2P = 5431

⇒ 0.01P = 5431

⇒ P = 543100

∴ The correct answer is Rs. 543100.

In syllogistic arguments, which are a form of logical reasoning involving two premises and a conclusion, each of the components plays a specific role governed by certain rules. 

Key Points

• (A) The predicate term of the conclusion is the major term.
• This statement is correct. In a syllogism, the major term is indeed the predicate of the conclusion.
• (B) The subject term of the conclusion is the minor term.
• This statement is also correct. The minor term serves as the subject in the conclusion.
• (C) The middle term must occur only once in the premise.
• This statement is incorrect. The middle term must appear in each of the premises once and be excluded from the conclusion. The error in this statement lies in its implication that the middle term should only occur in one of the premises, not both.
• (D) The middle term must be distributed at least once in the conclusion.
• This statement is incorrect. The middle term, by definition, should not appear in the conclusion at all. It connects the two premises and is not part of the conclusion.

Thus, the correct answer is: (C) and (D) Only.

The correct answer is:Statement I is correct but Statement II is incorrect.

Key Points

• Statement I: This statement accurately reflects the vision of NEP 2020.
• The policy encourages all higher education institutions (HEIs) to strive for graded autonomy and empower their Boards of Governors (BOGs) with decision-making authority.
• Statement II: This statement is inaccurate.
• While the BOG plays a crucial role in institutional development, they are not solely responsible for it.
• According to NEP 2020, other stakeholders like faculty, students, and alumni also contribute to the development plan.

The correct answer is- Upamiti.

Key Points

• Analogy in philosophical or logical terms often corresponds to the concept of comparison or similarity between two different things based on their shared characteristics.
• In the context of traditional Indian epistemology, which categorizes various means of acquiring knowledge (Pramāṇas),
• The term that most closely aligns with the concept of analogy is Upamiti.

Additional Information

• Anumiti corresponds to inference. It involves deriving a new conclusion based on premises that are observed, rather than through direct observation or comparison.
• Upamiti corresponds to analogy or comparison.
• This is where the knowledge of something is obtained through its similarity to another thing that is already known.
• Agama refers to authoritative testimony or verbal testimony.
• It is the acceptance of words or knowledge from a reliable source, such as scriptures or experts, that cannot be easily verified through direct observation.
• Pratyaksha corresponds to perception. It refers to direct observation or sensory experience as a means of acquiring knowledge about the world.

Given:

Distance = 140 km

Speed of A = 80 km/h

Speed of B = 40 km/h

Calculation:

Combined speed = 80 km/h + 40 km/h = 120 km/h

Now, convert the time from minutes to hours:

45 minutes = 45/60 hours = 0.75 hours

Distance = 120 km/h × 0.75 h = 90 km 

So, they will be exactly 90 kilometers apart 45 minutes before they meet

∴ The correct answer is 90 km.

The correct answer is - (A) - (II), (B) - (IV), (C) - (I), (D) - (III) .

The correct response is - Bhakti.

Key Points

• Bhakti is not considered a value as propounded by the Indian traditional concept of Purushartha.
• The traditional Purusharthas consist of :

1. Dharma (righteousness, moral values),
2. Artha (wealth, prosperity),
3. Kama (desires, pleasures), and
4. Moksha (liberation, salvation).

• Bhakti (devotion) is a significant aspect of Indian spirituality and religious practice, but it is not classified as one of the four Purusharthas.

Important PointsThe concept of Purusharthas represents the four goals or aims of human life according to Hindu philosophy.

• Here's a brief overview of each:
• Dharma:
• Represents righteousness, moral values, and duties.
• Encourages adherence to ethical principles and societal norms.
• It's considered the foundation of human life that supports the other three Purusharthas.
• Artha:
• Signifies wealth, prosperity, and career.
• Focuses on achieving material success and financial stability through rightful means.
• Seen as necessary for a comfortable life and fulfillment of duties.
• Kama:
• Denotes desires and pleasures, including emotional and sensual love.
• Emphasizes the importance of fulfilling lawful desires and enjoying life’s pleasures.
• Encourages balance; fulfillment without compromising Dharma and Artha.
• Moksha:
• Translates to liberation or salvation.
• Represents the ultimate goal of escaping the cycle of birth and death (samsara) by realizing the true Self.
• Achieved through spiritual practices, detachment from material desires, and realization of one's connection with the divine.

The correct answer is - (B) and (E) Only.

The correct response is Statement I is incorrect but Statement II is correct.

Key Points 

Statement (I): Not every medium has its own grammar.

This statement is incorrect.

Every medium, by definition, develops its own grammar. The way we understand and interpret information is influenced by the medium's specific characteristics and constraints — what works in one medium often does not work in another because each has developed its own set of rules and conventions or "grammar."

Statement (II): Each media grammar has evolved over a period of time and continues to change.

This statement is correct. The grammar of any medium is not static. It evolves over time in response to changes in technology, culture, audience expectations, and many other factors. New genres, formats, and conventions emerge, and existing ones are adapted or discarded. For instance, the grammar of online communication has evolved rapidly with the advent of social media, adapting to new norms and introducing elements like hashtags and emojis as part of its grammar.

The correct response is Both Statement I and Statement II are correct.

Key Points 

To determine the correctness of the given statements, we need to convert the binary numbers to hexadecimal (base 16) and vice versa, and compare the results.

Statement I: (1011101)2 = (5D)16

First, let's convert the binary number (1011101_2) to hexadecimal (base 16):

Divide it into groups of four (from right to left), adding leading zeros if necessary: (0101; 1101).

Convert each group to its hexadecimal equivalent: (0101) is (5) and (1101) is (D).

So, the binary number (1011101_2) is equal to (5D_{16}).

Statement II: (C2)16 = (11000010)2

Now, let's convert the hexadecimal number (C2_{16}) to binary (base 2):

Convert each hexadecimal digit to its four-bit binary equivalent: (C) is (1100) and (2) is (0010).

So, (C2_{16}) is (11000010_2).

 

Since both statements when checked were found to be correctly matched, the answer is: Both Statement I and Statement II are correct.

The correct answer is - It can limit opportunities for students' creavity and critical thinking.

The correct answer is - Psychosocial effect.

Key Points

• The term "psychosocial effect" refers to the influence that social aspects (such as the age, status, or role of the researcher) have on the psychological processes of individuals, including their behavior and attitudes.
• In this context, the age of the researcher influences the participant through both psychological perception and social interactions.

The correct answer is - Statement I is incorrect but Statement II is correct. 

Key Points 

• Statement

(I) is incorrect.

• Arguments from analogy are not deductive in nature.
• Statement

(II) is correct.

• Arguments from analogy are a type of inductive reasoning.
• Inductive reasoning moves from specific observations to general conclusions, providing probability rather than certainty.
• Deductive arguments are judged as valid/invalid, whereas inductive arguments (including analogies) are judged as strong/weak and cogent/incogent.
• Therefore, arguments from analogy are considered inductive and evaluated in terms of strength, not validity.

Additional Information

**Deductive

Arguments:

**

• Start with general premises to reach a specific conclusion.
• If the premises are true and reasoning valid, the conclusion must be true.
• Evaluated as valid/invalid and sound/unsound.

**Inductive

Arguments:

**

• Move from specific cases to broader generalizations.
• Conclusions are probable, not certain.
• Evaluated as strong/weak and cogent/incogent, not valid/invalid.

The correct answer is - It is invalid argument and contains false premise and false conclusion.

Key Points

• Validity: This argument is not valid because of the fallacy of the undistributed middle term.
• Both premises use the term "cat" (the middle term), but neither premise distributes it (meaning applying it to all cats).
• This makes it impossible to logically draw the conclusion that all whales are dogs.
• However, the conclusions we can correctly draw should uphold the logical structure and direction of the relationship established by the premises.
• The correct logical deduction from the premises should be concerning dogs and cats related to whales but not that all whales are dogs, as there's no premise supporting the reversibility of the categorization.
• Therefore, the conclusion ("All whales are dogs") is also false.

Additional InformationSyllogistic reasoning :

• Syllogistic reasoning is a form of logical reasoning that originated with Aristotle's works on logic.
• It involves constructing a conclusion from two or more premises that are asserted or assumed to be true.
• A syllogism typically consists of three parts: two premises followed by a conclusion, each part containing a statement.
• The statements involve a subject and a predicate, which are linked by being either universally or particularly quantified (e.g., all, some).
• The key components of a syllogism include:
• Major Premise: The first premise, involving the major term (the predicate of the conclusion) and the middle term.
• Minor Premise: The second premise, involving the minor term (the subject of the conclusion) and the middle term.
• Conclusion: A logical deduction made based on the relationship established by the two premises, involving both the major and minor terms.

'SHYAM' → 19 + 8 + 25 + 1 + 19 = 66

'SHYAM' is coded as 66.

Hence, the correct answer is 66.

The correct answer is - Experimental research .

Key PointsExperimental research:

• Experimental research is designed to assess the effect of one specific variable or variables by manipulating them, while controlling for other extraneous variables.
• Focuses on determining cause-and-effect relationships.
• Involves an independent variable (manipulated) to observe its effect on a dependent variable (measured).
• Subjects are randomly assigned to experimental and control groups to minimize bias.

Additional InformationQualitative Research:

• Deals with descriptions and characteristics that can't be easily measured numerically.
• Involves interviews, observations, and textual analysis.
• Focuses on understanding concepts, thoughts, or experiences from the perspective of the study participants.
• Generally does not seek to find cause-and-effect relationships.

Longitudinal Research:

• Studies the same subjects over a period of time, potentially years or decades.
• Aims to observe changes and developments in the subject matter over time.
• Variables are not manipulated; instead, the research observes natural progressions.
• Often used in psychology, sociology, and medicine to study changes through life stages or over generations.

Correlational Research:

• Aims to find whether and how two variables are related.
• Unlike experimental research, it does not involve the manipulation of variables.
• Employs statistical methods to determine the strength and direction of relationships.
• While it can suggest a relationship between variables, it cannot determine cause and effect.

Shortcut Trick

Initial ratio of Water : Milk = 5 : 4 (Sum = 9 units).

Given 9 units = 27 litres ⇒ 1 unit = 3 litres.

Final ratio of Water : Milk = 3 :

1. Since Milk remains constant, equate milk parts: 3 : 1 × 4 = 12 : 4.

Increase in Water units = 12 − 5 = 7 units.

Quantity of water added = 7 × 3 = 21 litres.

∴ The correct answer is 21 litres.

Alternate Method

Given: Total mixture = 27 litres, Initial Ratio (W:M) = 5 : 4, Final Ratio (W:M) = 3 :

1. Formula: Quantity of component = (Ratio Part ÷ Total Parts) × Total Quantity

⇒ Initial Water = (5 ÷ 9) × 27 = 15 litres

⇒ Initial Milk = (4 ÷ 9) × 27 = 12 litres

⇒ Let the quantity of water added be 'x' litres.

⇒ New Water = 15 + x

⇒ New Milk = 12 (Since only water is added)

⇒ New Ratio (Water : Milk) = 3 : 1

⇒ (15 + x) ÷ 12 = 3 ÷ 1

⇒ 15 + x = 36

⇒ x = 36 − 15

⇒ x = 21 litres

∴ The correct answer is 21 litres.

Additional Information

Ratio Balancing Method

When one component in a mixture is added or removed, the other component remains constant. To solve, equalize the ratio parts of the constant component.

Alligation Rule

It relates the concentration of two mixtures. Quantity 1 ÷ Quantity 2 = (Concentration 2 − Mean) ÷ (Mean − Concentration 1).

Percentage to Ratio Conversion

A ratio of 5:4 can be viewed as water being (5/9)×100 ≈ 55.55% and milk being (4/9)×100 ≈ 44.44% of the total volume.

The correct answer is - Both (A) and (R) are correct and (R) is the correct explanation of (A).

Key Points

• Both the assertion and reason are correctly related.
• The assertion notes the severity of indoor air pollution in less developed countries.
• The reason correctly identifies a primary cause of this: the use of traditional cooking methods involving biomass and fossil fuels.
• These fuels, when burned in poorly ventilated spaces, lead to high levels of indoor air pollution, contributing to the health risks associated with such exposure in less developed countries.
• Therefore, (R) is a valid explanation for (A).

Additional InformationIndoor air pollution:

• Indoor air pollution refers to the contamination of the indoor environment due to the presence of various pollutants.
• Indoor air pollution can result from both outdoor sources that infiltrate indoor spaces and pollutants that originate within those spaces.
• Key sources include:
• The burning of solid fuels (wood, coal, dung) for cooking and heating, tobacco smoke, kerosene use.
• Emissions from building materials, mold, household cleaning products, and radon gas.
• It poses significant health risks like respiratory diseases, lung cancer, and heart problems.
• Addressing it necessitates improving ventilation, adopting cleaner energy solutions, and using safer materials and products.

The correct answer is - Both (A) and (R) are correct and (R) is the correct explanation of (A).

Key PointsAssertion (A): True.

• Coral reefs are indeed threatened because of the release of sewage into ocean waters near them.
• Sewage discharge can lead to increased nutrient levels in the water,
• Particularly nitrogen and phosphorus, which promote the growth of algae.
• Algae can smother corals by covering their surfaces, blocking the sunlight they need for photosynthesis, and degrading the quality of the water around them.
• This process can lead to coral stress and, ultimately, contribute to coral death, negatively impacting reef ecosystems.

Reason (R): True.

• The release of sewage in the ocean does tend to reduce the clarity of ocean water.
• Sewage often contains a variety of pollutants including organic materials, nutrients, and chemicals that can increase turbidity (cloudiness) of the water.
• This reduction in water clarity can limit the penetration of sunlight, which is crucial for the health of corals and the photosynthetic algae (zooxanthellae) living in their tissues.
• These algae provide corals with energy through photosynthesis and are essential for their survival.

Therefore, the reason (R) correctly explains the assertion (A).

Additional Information

• Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals.
• They are often referred to as the "rainforests of the sea" due to their astonishing diversity of life.
• Corals are made up of tiny organisms called polyps, which excrete a hard carbonate exoskeleton that provides support and protection.
• Over thousands to millions of years, these structures accumulate, forming the backbone of coral reefs.
