UGC NET Paper 1: Held on 6th Jan 2025 Shift 2 (Previous Year Paper)

Let the total population of state D be 100x.

=> Population above poverty: 72x.

Number of males above poverty: \(\frac{5}{12}\times72x= 2700000.\)

=> 30x = 2700000

x= 900000.

total population = 90 lacs.

Given that, population of state C is 9000000.

%above poverty population = 100 - 22 = 78%.

Above poverty population : \(9000000\times\frac{78}{100}= 7020000\).

Male population (above poverty) : \(7020000\times\frac{7}{13}=3780000.\)

Let the population of state C be 7x and that of state D be 4x.

Male population below poverty line of state C: \(7x\times\frac{22}{100}\times\frac{6}{11}=0.84x\).

% above poverty population = 100 - 28 = 72%.

Female population above poverty line of state D: \(4x\times\frac{72}{100}\times\frac{7}{12}=1.68x\)

Required ratio: \(\frac{0.84x}{1.68x}\) = 1:2

Let the total population of state F be x.

Females below poverty line of state F : \(\frac{20}{100}\times x \times \frac{3}{5}=0.12x.\) 

% above poverty population : 100 - 20 = 80%.

Males above poverty line of state F : \(\frac{80}{100}\times x \times\frac{3}{8}=0.3x.\)

Required ratio: \(\frac{0.12x}{0.3x}= 2:5\)

Given that, total population: 7000000.

Males below poverty line : \(\frac{16}{100}\times7000000\times\frac{5}{8}= 700000\)

% above poverty population : 100 - 16 = 84%

Females above poverty line : \(\frac{84}{100}\times7000000\times\frac{3}{7}=2520000.\)

Difference : 2520000 - 700000 = 1820000.

The correct answer is - For the Jain philosophers, verbal testimony (śabda pramāṇa) is a secondary inference

Key Points

• Jain Philosophy
• Contrary to the statement, Jain thinkers accept śabda (verbal testimony) as an independent pramāṇa when it comes from trustworthy persons (like omniscient beings or Tirthankaras).
• It is not treated as a mere subset or derivative of inference (anumāna).
• Buddhist Philosophy
• Most Buddhist schools (e.g., Yogācāra, Madhyamaka) do not accept śabda as an independent pramāṇa.
• They rely mainly on pratyakṣa (perception) and anumāna (inference) for valid knowledge.
• Mīmāṁsā School
• The Mīmāṁsakas place supreme importance on śabda as an independent and eternal pramāṇa.
• Especially in interpreting Vedic texts, śabda is treated as apauruṣeya (non-human origin).
• Vedānta Philosophy
• Śabda is a valid and essential source of knowledge, especially for understanding Brahman and Ātman.
• Like Mīmāṁsā, Vedānta also treats the Vedas as apauruṣeya and infallible.

Additional Information

• Pramāṇa (Means of Knowledge)
• In Indian philosophy, pramāṇa refers to the valid means by which knowledge is obtained.
• Common pramāṇas include:
• Pratyakṣa (Perception)
• Anumāna (Inference)
• Śabda (Verbal Testimony)
• Other pramāṇas like Upamāna (Comparison), Arthāpatti (Postulation), and Anupalabdhi (Non-cognition) are accepted by specific schools.
• Śabda as Independent Pramāṇa
• Accepted by: Mīmāṁsā, Vedānta, and Nyāya schools.
• Rejected as independent by: Buddhism and certain Materialist (Cārvāka) schools.
• Jains accept it independently under specific conditions (from omniscient beings).

The logic followed here is :-

• Water Quality Parameters
• pH measures the acidity or alkalinity of water and is crucial for chemical dosing in water treatment.
• BOD (Biochemical Oxygen Demand) indicates the amount of organic matter in water, which affects its quality and treatment.
• COD (Chemical Oxygen Demand) measures the total quantity of oxygen required to oxidize both organic and inorganic substances in water.
• Turbidity measures the clarity of water and is influenced by the presence of suspended particles.

Given:

The cost price of an article is 95% of its selling price.

Formula Used:

Profit = (SP - CP)

Profit% = (SP - CP)/CP × 100

where CP → Cost Price, SP → Selling Price

Calculations:

Let the selling price (SP) be 100 units.

Then, the cost price (CP) = 95% of SP = 95 units.

Profit = SP - CP = 100 - 95 = 5 units.

Percentage Profit = (5 / 95) × 100 = 5.26%

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

Key Points

• Population mean (μ) and (1/N) ∑Xi²
• The population mean (μ) is a measure of central tendency, representing the average value of a population.
• The expression (1/N) ∑Xi² is used to calculate the average of the squared values of the population data points.
• To find the population standard deviation (σ), we use the formula:

σ = sqrt((1/N) ∑Xi² - μ²)

• Matching LIST-I with LIST-II
• For each pair in LIST-I, we need to calculate the population standard deviation using the given mean (μ) and (1/N) ∑Xi² values.
• A. μ = 5, (1/N) ∑Xi² = 61:

σ = sqrt(61 - 5²) = sqrt(61 - 25) = sqrt(36) = 6

• B. μ = 6, (1/N) ∑Xi² = 85:

σ = sqrt(85 - 6²) = sqrt(85 - 36) = sqrt(49) = 7

• C. μ = 7, (1/N) ∑Xi² = 113:

σ = sqrt(113 - 7²) = sqrt(113 - 49) = sqrt(64) = 8

• D. μ = 8, (1/N) ∑Xi² = 145:

σ = sqrt(145 - 8²) = sqrt(145 - 64) = sqrt(81) = 9

Additional Information

• Population Standard Deviation
• The population standard deviation (σ) measures the dispersion of a set of data points in a population.
• It is the square root of the variance, which is the average of the squared differences from the mean.
• Formula: σ = sqrt((1/N) ∑(Xi - μ)²)
• Sample vs Population
• Population: The entire group being studied.
• Sample: A subset of the population used to make inferences about the population.
• Population parameters are denoted by Greek letters (e.g., μ for mean, σ for standard deviation).
• Sample statistics are denoted by Latin letters (e.g., x̄ for mean, s for standard deviation).

Given:

Four persons A, B, C, and D play a game of cards.

We need to determine the number of cards A has.

Calculation:

Let:

A = Number of cards with A

B = Number of cards with B

C = Number of cards with C

D = Number of cards with D

Forming the equations based on given conditions:

1. If A gives 8 cards to B, then B will have as many as C:

⇒ B + 8 = C       ...(i)

2. After giving 8 cards, A will have 3 less than C:

⇒ A - 8 = C - 3       ...(ii)

3. If A takes 6 cards from C, he will have twice as many as D:

⇒ A + 6 = 2D       ...(iii)

4. The total number of cards with B and D is 50:

⇒ B + D = 50       ...(iv)

Solving the equations:

From equation (i):

C = B + 8

Substituting this in equation (ii):

A - 8 = (B + 8) - 3

⇒ A - 8 = B + 5

⇒ A = B + 13       ...(v)

Substituting equation (i) in equation (iii):

A + 6 = 2D

Using equation (v):

(B + 13) + 6 = 2D

⇒ B + 19 = 2D

⇒ D = (B + 19) / 2       ...(vi)

Substituting equation (vi) in equation (iv):

B + (B + 19) / 2 = 50

Multiplying by 2 to eliminate fraction:

2B + B + 19 = 100

3B + 19 = 100

⇒ 3B = 81

⇒ B = 27

Using B = 27 in equation (i):

C = 27 + 8 = 35

Using B = 27 in equation (v):

A = 27 + 13 = 40

Using B = 27 in equation (vi):

D = (27 + 19) / 2 = 23

Final Answer:

A = 40

B = 27

C = 35

D = 23

∴ A has 40 cards.
