UGC NET Paper 1: Held on 8th Jan 2025 Shift 2 (Previous Year Paper)

Total number of students in College E during all the years:

2018 : 1300+1320=2620

2019 : 1100+480=1820

2020 : 540+480=1020

2021 : 1080+1140=2220

2022 : 1360+1300=2660

2023 : 2160+2540=4700

Answer : 3.

Boys in College D in 2020 = 1280

Boys in College D in 2021 = 1060

% decrease = \(\frac{1280-1060}{1280}=17\)% (approx.)

Avg. number of girls of College A = \(\frac{720+840+1380+1920+2580+2880}{6}=1720.\)

Calculation:

Total number of students in college in E in 2019 = 1820

Number of girls in college B in 2022 = 1180

Required percentage = (1820 - 1180) × 100/1180 = 54.23% ≈ 54%

Avg. number of boys in the year 2023 = \(\frac{2460+1960+2340+2440+2160}{5}=2272.\)

Given:

Train A speed: 45 km/h,

Train B speed: 36 km/h,

Bridge length: 1.2 km

Formula used:

Distance = Speed × Time

Calculations:

Train A speed (m/s):

⇒ 45 × (5/18) = 12.5 m/s

Train A time (s):

T = 2 × 60 = 120 s

Train A total distance:

⇒ 12.5 × 120 = 1500 m

Train A length = Total distance covered by A - Bridge length

⇒ 1500 - 1200 = 300 m

Train B speed (m/s): 36 × (5/18) = 10 m/s

Train B time (s):

⇒ 3 × 60 = 180 s

Train B total distance:

⇒ 10 × 180 = 1800 m

Train B length = Total distance covered by B - Bridge length

⇒ 1800 - 1200 = 600 m

Ratio of lengths:

⇒ 300 : 600 = 1 : 2

∴ Ratio of lengths of train A and train B is 1 : 2.

The Correct answer is: A, C and D only

Key Points

• Statement A: The middle term is distributed in the major premise
• This statement is correct.
• Major premise is an A (Universal Affirmative: “All M are P”). In an A-proposition the subject (M) is distributed, so M is distributed in the major premise.
• Statement D: The middle term is distributed in the minor premise
• This statement is correct.
• Minor premise is an E (Universal Negative: “No S are M”). In an E-proposition the predicate (M) is distributed. Thus M is distributed in the minor premise.
• Statement C: It commits the fallacy of illicit-Major
• This statement is correct.
• The conclusion is an E (Universal Negative: “No P are S”). In an E-proposition both subject and predicate are distributed, so the major term (P) is distributed in the conclusion.
• Illicit-Major occurs when the major term is distributed in the conclusion but was not distributed in the major premise. Here the major premise is A (“All M are P”), where P is the predicate of an A — the predicate of an A is undistributed. So P is not distributed in the major premise but is distributed in the conclusion → illicit-Major.
• Statement B: It commits the fallacy of illicit-Minor
• This statement is incorrect.
• Illicit-Minor would require the minor term to be distributed in the conclusion but not distributed in the minor premise. In our case the conclusion is E (“No P are S”) — the minor term S is the predicate of the conclusion and therefore distributed in the conclusion.
• However the minor premise is E (“No S are M”), an E-proposition in which S (the subject) is already distributed. So the minor term is distributed in the premise as well; there is no illicit-Minor.
• Statement E: The conclusion does not distribute either of the terms
• This statement is incorrect.
• The conclusion is an E-proposition, which distributes both its subject and predicate. Thus the conclusion does distribute the major term (and also the minor term). Therefore the claim that the conclusion distributes neither term is false.

Additional Information

• Distribution rules (quick reminder)
• A (All S are P): subject distributed, predicate undistributed.
• E (No S are P): both subject and predicate distributed.
• I (Some S are P): neither term distributed.
• O (Some S are not P): predicate distributed, subject undistributed.
• Illicit Major vs Illicit Minor (definition)
• Illicit-Major: the major term is distributed in the conclusion but not distributed in the major premise — invalid.
• Illicit-Minor: the minor term is distributed in the conclusion but not distributed in the minor premise — invalid.
• Why AEE-1 is invalid
• In AEE Figure 1 the major premise (A) fails to distribute the major term while the conclusion (E) distributes it — this exactly produces illicit-Major, so the syllogism is invalid.
• Concise verdict
• Statements A and D are true (middle term distributed in both premises); C is true (illicit-Major occurs); B and E are false. Hence the correct choice is Option 1: A, C and D only.

Given:

Principal (P) = Rs. 1,00,000

Rate (r) = 10% per annum

Time (t) = 1 year

Formula used:

Amount (A) = P(1 + r/n)^nt

Compound Interest (CI) = A - P

Where n = number of times interest is compounded per year

Calculations:

r = 10/2 = 5% per half-year

n = 2

A = 100000(1 + 0.05)²

⇒ A = 100000(1.05)²

⇒ A = 100000 × 1.1025 = 110250

CI = 110250 - 100000

⇒ CI = 10250

∴ The compound interest is Rs. 10,250.

Given:

Total days = 10 days

Total payment = Rs. 10,000

Man is 50% more efficient than boy.

Formula used:

Efficiency ratio = Work ratio = Wage ratio

Calculations:

Efficiency ratio (Man : Boy) = 150 : 100 = 3 : 2

Work ratio (Man : Boy) = 3 : 2

Wage ratio (Man : Boy) = 3 : 2

Total ratio = 3 + 2 = 5

Total daily wage = 10000 / 10 = 1000

Man's daily wage ratio = 3/5

Boy's daily wage ratio = 2/5

Man's daily wage = (3/5) × 1000 = Rs. 600

Boy's daily wage = (2/5) × 1000 = Rs. 400

Difference = 600 - 400 = Rs. 200

∴ The difference between the daily wages of the man and the boy is Rs. 200.
