UGC NET Paper 1: 5th January 2026 Shift 2 (Previous Year Paper)

Given:

Number of cities = 6

Bike tourists:

Shimla = 382

Jaipur = 374

Delhi = 362

Agra = 340

Goa = 298

Manali = 284

Formula used:

Average = Total ÷ Number of observations

Calculation:

Total Bike tourists = 382 + 374 + 362 + 340 + 298 + 284

⇒ Total = 2040

⇒ Average = 2040 ÷ 6

⇒ Average = 340

∴ The average number of tourists who travelled by Bike is 340.

Given:

Six cities: Shimla, Jaipur, Delhi, Agra, Goa, Manali

Five modes: Air, Bike, Train, Bus, Car

Condition: Total tourists > 1600

Formula used:

Total tourists of a city = Sum of all five modes

Calculation:

Shimla = 348 + 382 + 376 + 344 + 384

⇒ 1834 > 1600 ✔

Jaipur = 364 + 374 + 332 + 356 + 360

⇒ 1786 > 1600 ✔

Delhi = 296 + 362 + 388 + 326 + 312

⇒ 1684 > 1600 ✔

Agra = 296 + 340 + 370 + 284 + 264

⇒ 1554 < 1600 ✘

Goa = 366 + 298 + 318 + 310 + 298

⇒ 1590 < 1600 ✘

Manali = 348 + 284 + 326 + 316 + 336

⇒ 1610 > 1600 ✔

∴ Number of cities = 4.

Given:

Tourists visited Jaipur by Car = 360

Tourists visited Goa by Bus = 310

Formula used:

Required ratio = Jaipur (Car) : Goa (Bus)

Calculation:

Required ratio = 360 : 310

⇒ Divide both terms by 10

⇒ 36 : 31

∴ The required ratio is 36 : 31.

Given:

Total tourists in Shimla = 348 + 382 + 376 + 344 + 384

Total tourists in Manali = 348 + 284 + 326 + 316 + 336

Formula used:

Percentage more = (Difference ÷ Manali total) × 100

Calculation:

Shimla total = 1834

Manali total = 1610

Difference = 1834 − 1610 = 224

⇒ Percentage more = (224 ÷ 1610) × 100

⇒ Percentage more ≈ 13.9%

Given:

Air travellers = Shimla + Jaipur + Delhi + Agra + Goa + Manali

Bus travellers = Shimla + Jaipur + Delhi + Agra + Goa + Manali

Formula used:

Difference = Total Air − Total Bus

Calculation:

Total Air = 348 + 364 + 296 + 296 + 366 + 348

⇒ Total Air = 2018

Total Bus = 344 + 356 + 326 + 284 + 310 + 316

⇒ Total Bus = 1936

⇒ Difference = 2018 − 1936

⇒ Difference = 82

∴ The difference is 82 tourists.

Net % change = a + b + (ab / 100)

Where,

a = 20

b = −10

Calculation:

Net % change = 20 + (−10) + (20 × −10) / 100

= 20 − 10 − 2

= 8%

∴ Area increases by 8%

∴ The correct option is 4.

Given:

To appear in the NET exam, one must have 55% marks in the subject at the post-graduation level.

Given:

Quoted price for 1 dozen (12 pairs) of gloves = ₹120

Discount = 20%

Budget = ₹16

Formula used:

Effective price = Quoted price - (Discount% × Quoted price)

Cost per pair = Effective price ÷ Quantity

Number of pairs = Budget ÷ Cost per pair

Calculation:

Effective price = ₹120 - (20% × ₹120)

⇒ Effective price = ₹120 - ₹24 = ₹96

Cost per pair = ₹96 ÷ 12

⇒ Cost per pair = ₹8

Number of pairs = ₹16 ÷ ₹8

⇒ Number of pairs = 2

∴ The correct answer is 2 pairs of gloves.

The correct answer is - Ozone

Key Points

• Ozone is a secondary pollutant.
• It is not emitted directly into the atmosphere but forms when primary pollutants such as nitrogen oxides (NO_x) and volatile organic compounds (VOCs) react in the presence of sunlight.
• It is a major component of photochemical smog, particularly in urban areas with high vehicle emissions.
• Ozone in the troposphere (near Earth's surface) is harmful to human health and the environment, unlike the ozone layer in the stratosphere, which protects us from ultraviolet radiation.

Additional Information

• Primary vs Secondary Pollutants
• Primary pollutants are directly emitted from sources such as vehicles, industries, and natural events (e.g., volcanic eruptions). Examples include carbon monoxide (CO), sulphur dioxide (SO₂), and nitrogen dioxide (NO₂).
• Secondary pollutants are not emitted directly but form when primary pollutants react in the atmosphere. Examples include ozone (O₃) and peroxyacetyl nitrate (PAN).
• Formation of Ozone
• Ozone forms when nitrogen oxides (NO_x) and volatile organic compounds (VOCs) react with sunlight through photochemical processes.
• It is more prevalent during sunny days and in areas with heavy traffic or industrial activity.
• Effects of Ozone

The correct answer is - C and D Only

Key Points

• C and D propositions are logically related such that they cannot both be false, but they can both be true.
• This relationship occurs because:
• Proposition C (Some pitcher-plants are carnivores) affirms the existence of at least one carnivorous pitcher-plant.
• Proposition D (Some pitcher-plants are not carnivores) affirms the existence of at least one non-carnivorous pitcher-plant.
• Both statements can coexist because they describe different subsets within the category of pitcher-plants.
• However, it is impossible for both statements to be false simultaneously because:
• If C is false, it implies no pitcher-plants are carnivores.
• If D is false, it implies all pitcher-plants are carnivores.
• These two implications contradict each other.

Additional Information

• Contradictory propositions
• Propositions A (All pitcher-plants are carnivores) and B (No pitcher-plants are carnivores) are contradictory.
• They cannot both be true at the same time but can both be false if some pitcher-plants are carnivores and some are not.
• Sub-contrary relationship
• Propositions C and D exhibit a sub-contrary relationship, which means they can both be true but cannot both be false.
• This type of logical relationship is commonly seen in categorical logic.
• Logical compatibility
• C and D are logically compatible and reflect different subsets of the universal set of pitcher-plants.
• This compatibility allows for coexistence of both propositions within the logical framework.

.

The correct answer is - A, B, and C Only

Key Points

• Statement A: "Some non-sedans are cars."
• This means there exists at least one object that is both a car and not a sedan.
• Statement B: "Some cars are not non-sedans."
• This is logically equivalent to Statement A because if some cars are not non-sedans, it means those cars must be sedans.
• Statement C: "Some cars are sedans."
• This is also logically equivalent to Statement A because if some cars are sedans, it implies some non-sedans are cars.
• Statement D: "Some sedans are cars."
• This statement does not add new information because sedans are already a subset of cars.
• It is not logically equivalent to A, B, or C as it is a tautology.

Additional Information

• Logical Equivalence
• Two statements are logically equivalent if they always have the same truth value.
• In this question:
• Statement A implies that non-sedans exist as a subset of cars.
• Statement B rephrases the same idea, as it negates "not non-sedans," leading to sedans.
• Statement C directly states the same subset relation as A and B.
• Subset Relationship
• The term "some" indicates the existence of at least one element in the subset.
• In this case, the subset relationship between cars, sedans, and non-sedans is critical for determining logical equivalence.
• Tautology
• Statement D is a tautology because it restates a universally known fact: "All sedans are cars."
• Tautologies are always true but are not equivalent to the other statements in this case.

The correct answer is: Assertion (A) is correct but Reason (R) is not correct.

Key Points

• Assertion (A) is correct.
• According to Nyāya (Classical Indian Logic), the inference "Sound is eternal because it is produced" is logically fallacious.
• Here, producedness (Kṛtakatva) is the Hetu (middle term), while eternality (Nityatva) is the property to be established.
• Nyāya philosophers maintain that whatever is produced is necessarily non-eternal (Anitya).
• Therefore, the reason supports the opposite conclusion and results in a Viruddha Hetvābhāsa (contradictory reason).
• Reason (R) is not correct.
• The defect in the argument does not arise because the middle term is too narrow.
• A narrow middle term is associated with the fallacy called Asādhāraṇa Hetu.
• In the present case, the middle term directly contradicts the conclusion that is intended to be proved.
• Hence, the fallacy is Viruddha Hetvābhāsa, not a case of a narrow middle term.
• Therefore, Assertion (A) is true and Reason (R) is false.

Additional Information

• Viruddha Hetvābhāsa
• A fallacy in which the reason offered proves the exact opposite of the proposition intended to be established.
• Example: "Sound is eternal because it is produced."
• Hetvābhāsa
• Literally means "fallacious reason" or "semblance of a valid reason".
• It refers to an apparently valid inference that fails due to a defect in the middle term.
• Important Terms in Nyāya Logic
• Pakṣa – The subject under consideration (Sound).
• Sādhya – The property to be proved (Eternality).
• Hetu – The reason offered in support of the conclusion (Producedness).
• Vyāpti – The universal and invariable relation between the Hetu and the Sādhya.
