UGC NET Paper 1: Held on 3rd Sept 2024 Shift 1 (Previous Year Paper)

Given:

Number of people in City A = 14.4 lakhs

Ratio in City A (I ∶ II ∶ III) = 1 ∶ 3 ∶ 2

Number of people in City B = 16 lakhs

Ratio in City B (I ∶ II ∶ III) = 2 ∶ 3 ∶ 3

Number of people in City C = 19.2 lakhs

Ratio in City C (I ∶ II ∶ III) = 1 ∶ 1 ∶ 2

Number of people in City E = 12 lakhs

Ratio in City E (I ∶ II ∶ III) = 1 ∶ 3 ∶ 1

Formula used:

People in age group = (Total people in city) × (Ratio for age group) / (Sum of ratio)

Calculation:

Age Group II in City A = 14.4 × 3 / (1 + 3 + 2)

⇒ 14.4 × 3 / 6

⇒ 7.2 lakhs

Age Group II in City B = 16 × 3 / (2 + 3 + 3)

⇒ 16 × 3 / 8

⇒ 6 lakhs

Age Group III in City C = 19.2 × 2 / (1 + 1 + 2)

⇒ 19.2 × 2 / 4

⇒ 9.6 lakhs

Age Group III in City E = 12 × 1 / (1 + 3 + 1)

⇒ 12 × 1 / 5

⇒ 2.4 lakhs

Difference:

⇒ (Age Group II of City A + City B) - (Age Group III of City C + City E)

⇒ (7.2 + 6) - (9.6 + 2.4)

⇒ 13.2 - 12

⇒ 1.2 lakhs

∴ The difference is 1.2 lakhs.

Given:

City C

Current Number of People = 19.2 lakhs = 1920000

Age Group Ratio I : II : III = 1 ∶ 1 ∶ 2

People turning 21 next year = 16000

Newborns next year = 32000

People in Group III remain the same

Formula used:

New number of people in Age Group I = Current Group I + Newborns - People turning 21

New number of people in Age Group II = Current Group II + People turning 21

New number of people in Age Group III = Current Group III

Calculations:

Current Group I = \(\dfrac{1920000}{4} = 480000\)

Current Group II = \(\dfrac{1920000}{4} = 480000\)

Current Group III = \(\dfrac{1920000}{2} = 960000\)

⇒ New Group I = 480000 + 32000 - 16000 = 496000

⇒ New Group II = 480000 + 16000 = 496000

⇒ New Group III = 960000

New Ratio:

Group I : Group II : Group III = 496000 ∶ 496000 ∶ 960000

⇒ New Ratio = 31 ∶ 31 ∶ 60

∴ The new ratio of people in different age groups in city C is 31 ∶ 31 ∶ 60.

Given:

Number of people in City D = 12.8 lakhs = 1280000

Ratio of age groups in City D (I : II : III) = 3 ∶ 1 ∶ 4

Number of people in City B = 16 lakhs = 1600000

Ratio of age groups in City B (I : II : III) = 2 ∶ 3 ∶ 3

Formula used:

Percentage increase = \(\dfrac{\text{Difference}}{\text{Value of Age Group II (City B)}} \times 100\)

Calculations:

People in Age Group III of City D = \(\dfrac{4}{8} \times 1280000 = 640000\)

People in Age Group II of City B = \(\dfrac{3}{8} \times 1600000 = 600000\)

⇒ Difference = 640000 - 600000 = 40000

⇒ Percentage increase = \(\dfrac{40000}{600000} \times 100 = 6.67%\) = \(6\frac{2}{3}\)%

∴ The number of people in age group III of city D is \(6\frac{2}{3}\)% more than that of age group II of city B.

Given:

City A: Total population = 14.4 lakhs = 1440000

City A age group ratio (I : II : III) = 1 ∶ 3 ∶ 2

City D: Total population = 12.8 lakhs = 1280000

City D age group ratio (I : II : III) = 3 ∶ 1 ∶ 4

City C: Total population = 19.2 lakhs = 1920000

City C age group ratio (I : II : III) = 1 ∶ 1 ∶ 2

City E: Total population = 12 lakhs = 1200000

City E age group ratio (I : II : III) = 1 ∶ 3 ∶ 1

Formula used:

Number of people in Age Group I = \(\dfrac{\text{Ratio of Age Group I}}{\text{Total Ratio}} \times \text{Total Population}\)

Calculations:

People in Age Group I of City A = \(\dfrac{1}{6} \times 1440000 = 240000\)

People in Age Group I of City D = \(\dfrac{3}{8} \times 1280000 = 480000\)

People in Age Group I of City C = \(\dfrac{1}{4} \times 1920000 = 480000\)

People in Age Group I of City E = \(\dfrac{1}{5} \times 1200000 = 240000\)

⇒ Total for Age Group I (City A and D) = 240000 + 480000 = 720000

⇒ Total for Age Group I (City C and E) = 480000 + 240000 = 720000

Ratio:

City A and D : City C and E = 720000 : 720000

⇒ Ratio = 1 ∶ 1

∴ The ratio of the number of people of age group I of cities A and D together to the number of people of age group I of cities C and E together is 1 ∶ 1.

Given:

Number of people and age group ratios for each city:

City A: Total population = 14.4 lakhs = 1440000, Ratio (I : II : III) = 1 ∶ 3 ∶ 2

City B: Total population = 16 lakhs = 1600000, Ratio (I : II : III) = 2 ∶ 3 ∶ 3

City C: Total population = 19.2 lakhs = 1920000, Ratio (I : II : III) = 1 ∶ 1 ∶ 2

City D: Total population = 12.8 lakhs = 1280000, Ratio (I : II : III) = 3 ∶ 1 ∶ 4

City E: Total population = 12 lakhs = 1200000, Ratio (I : II : III) = 1 ∶ 3 ∶ 1

Formula used:

Number of people in Age Group I = \(\dfrac{\text{Ratio of Age Group I}}{\text{Total Ratio}} \times \text{Total Population}\)

Calculations:

People in Age Group I of City A = \(\dfrac{1}{6} \times 1440000 = 240000\)

People in Age Group I of City B = \(\dfrac{2}{8} \times 1600000 = 400000\)

People in Age Group I of City C = \(\dfrac{1}{4} \times 1920000 = 480000\)

People in Age Group I of City D = \(\dfrac{3}{8} \times 1280000 = 480000\)

People in Age Group I of City E = \(\dfrac{1}{5} \times 1200000 = 240000\)

Result:

Cities with more than 4 lakh people in Age Group I: City C, and City D

∴ The number of cities where the population of age group I is more than 4 lakhs is two.

Given:

Three positive numbers are in the ratio 2 ∶ 3 ∶ 4. If the sum of their squares is 2349.

Formula used:

Let the numbers be 2x, 3x, and 4x.

The sum of their squares = (2x)² + (3x)² + (4x)²

Calculation:

(2x)² + (3x)² + (4x)² = 2349

⇒ 4x² + 9x² + 16x² = 2349

⇒ 29x² = 2349

⇒ x² = 81

⇒ x = 9

The correct answer is 'Temporal separation'.

Key Points

• Temporal separation:
• In conventional media, there is often a time delay between the production of content and its consumption by the audience.
• This delay can be due to various factors such as editing, broadcasting schedules, and distribution processes.
• For example, a television show might be filmed weeks or even months before it is aired to the public.

Additional Information

• This term does not accurately describe the relationship between content production and consumption in conventional media.
• Imaginary hurdles would imply non-existent or hypothetical barriers, which is not the case in traditional media workflows.
• Free marketing:
• Free marketing is unrelated to the timing or process of content production and consumption.
• It refers to the promotion of products or services without incurring costs, which is a different aspect of media management.
• Technological over-dependence:
• Technological over-dependence highlights reliance on technology, but it does not address the temporal aspect of content production and consumption.
• While technology plays a significant role in media, the key issue here is the time lag, not over-dependence.

The correct answer is '8 years'

Key Points

• Simple Interest Formula:
• The formula for simple interest is SI = (P * R * T) / 100, where SI is the simple interest, P is the principal amount, R is the rate of interest per annum, and T is the time in years.
• Doubling the Principal:
• To find the time required for the principal to double, we need the amount (A) to be twice the principal (P), i.e., A = 2P.
• The formula for amount in simple interest is A = P + SI. Since A = 2P, we have 2P = P + SI, which simplifies to SI = P.
• Substituting SI = P in the simple interest formula, we get P = (P * R * T) / 100.
• Canceling out P from both sides, we get 1 = (R * T) / 100.
• Rearranging the equation, we get T = 100 / R.
• Given R = 12.5%, we have T = 100 / 12.5 = 8 years.

Additional Information

• Other Options:
• 10 years: This would be correct if the interest rate was 10% per annum, as T = 100 / 10 = 10 years.
• 6 years: This would be correct if the interest rate was approximately 16.67% per annum, as T = 100 / 16.67 ≈ 6 years.
• 12 years: This would be correct if the interest rate was approximately 8.33% per annum, as T = 100 / 8.33 ≈ 12 years.

The correct answer is 'B, C and E Only'

Key Points

• Softening of hard water:
• Hard water contains high concentrations of calcium and magnesium ions, which can cause scale buildup in pipes and reduce the effectiveness of soap.
• Softening of hard water is the process of removing these calcium and magnesium ions to make the water suitable for household and industrial use.
• Boiling:
• Boiling precipitates out temporary hardness caused by bicarbonates of calcium and magnesium.
• This method is effective only for temporary hardness, not for permanent hardness.
• Lime Soda:
• This method involves adding lime (calcium hydroxide) and soda ash (sodium carbonate) to hard water.
• It precipitates out calcium and magnesium ions as their respective carbonates, which can be filtered out.
• Ion Exchange:
• Ion exchange resins replace calcium and magnesium ions with sodium ions, effectively softening the water.
• This method is suitable for both temporary and permanent hardness and is widely used in water softeners.

Additional Information

• Aeration:
• Aeration involves mixing water with air to remove dissolved gases like carbon dioxide and oxidize dissolved metals such as iron and manganese.
• It is not effective for softening hard water as it does not remove calcium and magnesium ions.
• Ozonation:
• Ozonation uses ozone to disinfect water and oxidize organic and inorganic substances.
• It is primarily used for water purification and disinfection, not for softening hard water.

The correct answer is 768 MB of memory is used for the 12 music tracks.

Key Points

• Total length of the tracks:

• Storage required per minute:
• Each minute of music requires 12 MB of storage.
• Total storage required:
• Multiply the total length by the storage required per minute: 64 minutes * 12 MB = 768 MB.

Additional Information

• Incorrect Options:
• 512 MB of memory is used for the 12 music tracks: This is incorrect because 512 MB would imply a shorter total music length or lower storage requirement per minute.
• 1 GB of memory is used for the 12 music tracks: This is incorrect since 1 GB equals 1024 MB, which is more than the calculated 768 MB.
• If the tracks are to be stored in MP3 format, then each music track will be reduced in size by 90%. The storage that the 12 tracks would require is 69.12 MB: While this option considers compression, it doesn't apply to the given conditions of the problem which specify uncompressed storage requirements.

Given:

Let L and M be the sum and average of four consecutive odd numbers (a, b, c, and d) respectively.

And, P and Q be the sum and average of three consecutive even numbers (x, y, and z) respectively.

M = Q - 6

P = L - 16

Formula used:

Sum of four consecutive odd numbers: L = a + b + c + d

Average of four consecutive odd numbers: M = L / 4

Sum of three consecutive even numbers: P = x + y + z

Average of three consecutive even numbers: Q = P / 3

Calculation:

Let the four consecutive odd numbers be (2n+1), (2n+3), (2n+5), (2n+7)

⇒ L = (2n+1) + (2n+3) + (2n+5) + (2n+7)

⇒ L = 8n + 16

⇒ M = (8n + 16) / 4

⇒ M = 2n + 4

Let the three consecutive even numbers be (2m), (2m+2), (2m+4)

⇒ P = (2m) + (2m+2) + (2m+4)

⇒ P = 6m + 6

⇒ Q = (6m + 6) / 3

⇒ Q = 2m + 2

Given: M = Q - 6

⇒ 2n + 4 = (2m + 2) - 6

⇒ 2n + 4 = 2m - 4

⇒ 2n - 2m = -8

⇒ n - m = -4

Given: P = L - 16

⇒ 6m + 6 = 8n + 16 - 16

⇒ 6m + 6 = 8n

⇒ 3m + 3 = 4n

⇒ 3m = 4n - 3

Substitute n = m - 4

⇒ 3m = 4(m - 4) - 3

⇒ 3m = 4m - 16 - 3

⇒ 3m = 4m - 19

⇒ m = 19

Substitute m = 19

⇒ n = 15

Now, M = 2n + 4

⇒ M = 2(15) + 4

⇒ M = 30 + 4

⇒ M = 34

∴ The correct answer is option (2).

The correct answer is 'impaires'

Key Points

• Impact of Over-Fertilization on Lakes:
• Over-fertilization of lakes, also known as eutrophication, leads to an excessive growth of algae and aquatic plants due to the high nutrient levels, primarily nitrogen and phosphorus.
• As these plants and algae die and decompose, the process consumes a significant amount of oxygen in the water, creating hypoxic or anoxic conditions.
• This depletion of oxygen can severely impair the quality of fish produced as many fish species require well-oxygenated water to survive and thrive.

Additional Information

• Analysis of Other Options:
• Does not change:
• This is incorrect because over-fertilization significantly alters the aquatic environment, particularly affecting the oxygen levels and overall water quality.
• Impoves:
• This is incorrect as the initial increase in nutrients may temporarily boost plant and algal growth, but the resultant oxygen depletion ultimately degrades water quality and fish health.
• First improves then impaires:
• While there may be a brief period of increased plant growth, the overall and more significant impact is the impairment of water quality and fish health due to oxygen depletion.

The correct answer is 'internal validity'.

Key Points

• Internal validity:
• Internal validity refers to the degree to which a study accurately establishes a causal relationship between variables, ensuring that the results are due to the independent variable and not other factors.
• In qualitative research, 'credibility' is akin to internal validity as it ensures that the findings are believable and accurately represent the participants' experiences.
• Credibility in qualitative research is achieved through techniques such as prolonged engagement, persistent observation, and member checking.

Additional Information

• External validity:
• External validity refers to the extent to which the results of a study can be generalized to other settings, populations, and times.
• It is not equivalent to 'credibility' in qualitative research, which focuses on the trustworthiness of the findings rather than generalizability.
• Objectivity:
• Objectivity involves the removal of researcher bias and ensuring that the findings are based solely on the data collected.
• While important, objectivity is not directly equivalent to 'credibility' in qualitative research.
• Reliability:
• Reliability refers to the consistency and repeatability of the findings over time and across different researchers.
• In qualitative research, the equivalent concept to reliability is 'dependability', not 'credibility'.

Given:

If a person travels in a car at a speed of 36 km/hour, then he will reach his destination on time. He covers half the journey in (4/5)^th time.

Formula used:

Distance (D) = Speed (S) × Time (T)

Calculations:

Let the total distance be D and total time be T.

Given speed = 36 km/hour

So, D = 36 × T

Half journey distance = D/2

Half journey time = (4/5)T

Speed for half journey = Distance/Time

Speed = (D/2) / (4/5)T

⇒ Speed = (D/2) × (5/4T)

⇒ Speed = D × (5/8T)

⇒ Speed = (36 × T) × (5/8T)

⇒ Speed = 36 × (5/8)

⇒ Speed = 180/8

⇒ Speed = 22.5 km/hour

Remaining time = T - (4/5)T

⇒ Remaining time = T/5

Remaining distance = D/2

Required Speed = Remaining distance / Remaining time

Required Speed = (D/2) / (T/5)

⇒ Required Speed = (36T/2) / (T/5)

⇒ Required Speed = 18T / (T/5)

⇒ Required Speed = 18 × 5

⇒ Required Speed = 90 km/hour

∴ The correct answer is option (3).

The correct answer is 'It has a non-inferentially contradicted middle term.'

Key Points

• Introduction to Nyaya School of Logic:
• The Nyaya School of Logic is one of the six orthodox schools of Hindu philosophy, focusing on logic, epistemology, and metaphysics.
• It emphasizes the importance of correct reasoning and argumentation.
• Fallacies, or errors in reasoning, are critically examined in Nyaya philosophy.
• Explanation of the Correct Answer:
• The statement "fire is cold because it is a substance" is fallacious due to a non-inferentially contradicted middle term.
• A non-inferentially contradicted middle term is one that directly contradicts observable reality or established knowledge.
• In this case, the middle term "substance" is being used to infer that fire is cold, which contradicts the observable fact that fire is hot.

Additional Information

• Other Options Explained:
• Option 2: The middle term has an impossible locus: This means the middle term cannot exist in the subject. However, "substance" can exist in fire, so this option is incorrect.
• Option 3: The middle term instead of proving its presence in major term proves its absence: This means the middle term negates the major term. In this case, "substance" does not negate "cold," so this option is incorrect.
• Option 4: The major term proves its presence: This option is vague and does not address the fallacy in the argument. Therefore, it is incorrect.

The correct answer is 'Far transfer'

Key Points

• Far transfer:
• Far transfer occurs when learning in one context or domain is applied to a different context or domain that appears to be quite different on the surface.
• In this case, the student is applying knowledge from geometry class to a spatial problem in an architect's office, which is a different context.
• This type of transfer requires a deeper understanding of the underlying principles and the ability to adapt and apply them in new situations.

Additional Information

• Near transfer:
• Near transfer refers to applying learned skills or knowledge to situations or problems that are very similar to the original context of learning.
• It involves minimal transformation of the original knowledge.
• Forward-reaching transfer:
• Forward-reaching transfer involves learning something with the intention of applying it to future situations or problems.
• It emphasizes the proactive use of knowledge in anticipating future applications.
• Low-road transfer:
• Low-road transfer refers to the automatic, unconscious transfer of skills to similar contexts.
• It involves little to no conscious thought and is usually based on habits or routines.

The correct answer is 'F' test-statistic in hypothesis testing

Key Points

• F-test in hypothesis testing:
• The F-test is used to compare the variances of two populations to determine if they are significantly different from each other.
• It is commonly used in the context of ANOVA (Analysis of Variance), regression analysis, and the comparison of multiple group means.
• The F-test uses both numerator and denominator degrees of freedom, which correspond to the degrees of freedom of the variance estimates being compared.

Additional Information

• t-test:
• The t-test is used to determine if there is a significant difference between the means of two groups.
• It uses a single degree of freedom based on the sample size minus one for each group being compared.
• Z-test:
• The Z-test is used for large sample sizes to determine if there is a significant difference between sample and population means or between two sample means.
• It assumes a normal distribution and typically does not use degrees of freedom in the same way as the t-test or F-test.
• χ2 (chi-square) test:
• The chi-square test is used to test the independence of two categorical variables or the goodness of fit of an observed distribution to a theoretical one.
• It uses degrees of freedom based on the number of categories minus one, but does not use numerator and denominator degrees of freedom like the F-test.

Mastering algebra helps in understanding calculus.

Key Points

• Positive-transfer of learning:
• Positive transfer occurs when learning in one context enhances a related performance in another context.
• This concept is crucial in education and skill development, as it allows previously acquired knowledge or skills to aid the learning of new, related tasks.
• In this case, mastering algebra provides a strong foundation for understanding and solving calculus problems, since algebraic manipulation is a critical component of calculus.

Additional Information

• Learning to play piano makes it more difficult to learn the violin:
• This is an example of negative transfer, where the skills learned in one area interfere with learning in another area.
• The techniques and finger placements for piano and violin are quite different, which can cause confusion and hinder learning.
• Knowing how to drive a car makes it harder to learn how to ride a bicycle:
• This is another example of negative transfer. The motor skills and balance required for riding a bicycle are different from those needed for driving a car.
• The habits and reflexes developed while driving do not directly apply to cycling and might even impede learning to ride a bicycle.
• Learning to speak French hinders learning Spanish:
• This is also an example of negative transfer. Although French and Spanish are both Romance languages, their grammar, vocabulary, and pronunciation are different enough to cause interference.
• Similarities might cause confusion, making it harder to distinguish between the two languages while learning.

The correct answer is 'A, C and D Only'

Key Points

• The main use of content analysis has been in the examination of printed texts and documents (Statement A):
• Content analysis is a research technique used to systematically analyze the content of communication.
• It has traditionally been used to analyze printed texts and documents to understand their meaning and context.
• Coding is crucial in content analysis (Statement C):
• Coding involves categorizing segments of text or data into meaningful categories.
• It is an essential step in content analysis as it allows researchers to quantify and interpret the content systematically.
• It is almost impossible to devise coding manuals that do not entail some interpretation on the part of coders (Statement D):
• Even the most detailed coding manuals require some level of interpretation by coders.
• This is because language and content can be ambiguous and context-dependent, necessitating subjective judgment.

Additional Information

• Content analysis lacks transparency (Statement B):
• This statement is incorrect. Content analysis is known for its systematic and transparent approach to analyzing data.
• Researchers document their coding procedures and criteria, making the process transparent and replicable.
• Other Incorrect Options:
• Option 1 (A, B and C Only): This option is incorrect because Statement B is incorrect.
• Option 2 (B, C and D Only): This option is incorrect because Statement B is incorrect.
• Option 4 (A, B and D Only): This option is incorrect because Statement B is incorrect.

The correct answer is 'Kurtosis'

Key Points

• Kurtosis:
• Kurtosis is a statistical measure that describes the sharpness or peakedness of the distribution of data.
• It helps in understanding the tails and the peak of the distribution compared to a normal distribution.
• High kurtosis indicates heavy tails and a sharp peak, while low kurtosis indicates light tails and a flatter peak.
• It is crucial in identifying outliers in data and understanding the distribution's behavior.

Additional Information

• Skewness:
• Skewness measures the asymmetry of the distribution of data.Positive skewness indicates a distribution with a longer tail on the right side, while negative skewness indicates a longer tail on the left side.
• Skewness does not provide information about the peak's sharpness or the tail's weight.
• Mean:
• The mean is the average of all data points in a distribution.
• It provides a measure of central tendency but does not indicate the shape or sharpness of the distribution.
• Median:
• The median is the middle value when data points are arranged in ascending or descending order.
• It also represents a measure of central tendency and does not provide information about the distribution's peak or tail behavior.

• Additionally, ethical living involves our behavior towards the environment (C).
• Material satisfaction (D) is not mentioned as a basis for ethical living in the passage.

Therefore, the correct answer is Option 3.

The correct answer is Option 1.

 

Key Points

• The statement "Culture is static" is incorrect because culture is actually dynamic, evolving over time.
• Cultures continuously change and adapt due to various internal and external influences.
• Therefore, stating that culture is static contradicts the adaptive nature of cultural norms and principles.

Therefore, the correct answer is Option 1.

 

Additional Information

• Option 2: It is correct to state that all cultures develop their ethical norms and principles over time.
• Option 3: Rational people of goodwill do exist in all cultures, contributing to ethical reflections and discussions.
• Option 4: Culture is indeed dynamic, constantly evolving with influences from various factors such as technological advances, social changes, and intercultural interactions.

The correct answer is Option 4.

 

Key Points

• The virtuous character traits mentioned in the context are integrity, honesty, faithfulness, and compassion.
• Psychophancy (flattering people for personal gain) is not considered a virtuous character trait.
• Therefore, the correct virtuous character traits are A (Integrity), C (Honesty), D (Compassion), and E (Faithfulness).

Therefore, the correct answer is Option 4.

The correct answer is Option 2.

 

Key Points

• The text emphasizes the importance of daily ethical reflection for effective moral leadership.
