UGC NET Paper 1: Held on 28th August 2024 Shift 2 (Previous Year Paper)

Given:

Number of magazines published in 2022 and 2020 from Table-2

Formula used:

Difference = Total magazines published in 2022 - Total magazines published in 2020

Calculation:

Total magazines published in 2022:

⇒ General = 34 (E) + 30 (H) = 64

⇒ Sports = 14 (E) + 8 (H) = 22

⇒ Film = 10 (E) + 14 (H) = 24

⇒ Business = 12 (E) + 8 (H) = 20

⇒ Total in 2022 = 64 + 22 + 24 + 20 = 130

Total magazines published in 2020:

⇒ General = 24 (E) + 20 (H) = 44

⇒ Sports = 6 (E) + 4 (H) = 10

⇒ Film = 6 (E) + 8 (H) = 14

⇒ Business = 8 (E) + 4 (H) = 12

⇒ Total in 2020 = 44 + 10 + 14 + 12 = 80

Difference between 2022 and 2020:

⇒ 130 - 80 = 50

∴ The difference between the number of magazines published in 2022 and 2020 is 50.

Given:

Number of readers of English Sports magazines from Table-1:

Readers in 2020 = 0.8 lakh

Readers from 2020 to 2023 = 0.8 (2020) + 1.2 (2021) + 2.0 (2022) + 2.1 (2023)

Formula used:

Ratio = Readers in 2020 / Total readers from 2020 to 2023

Calculation:

Total readers from 2020 to 2023 = 0.8 + 1.2 + 2.0 + 2.1 = 6.1 lakh

Ratio = 0.8 / 6.1

⇒ Ratio = 8 : 61

∴ The ratio between the number of readers in 2020 to the total number of readers from 2020 to 2023 is 8:61.

Given:

From Table-2:

Number of Hindi magazines published in 2020 and 2021:

⇒ General: 20 (2020) and 28 (2021)

⇒ Sports: 4 (2020) and 6 (2021)

⇒ Film: 8 (2020) and 12 (2021)

⇒ Business: 4 (2020) and 6 (2021)

Number of English magazines published in 2020 and 2021:

⇒ General: 24 (2020) and 30 (2021)

⇒ Sports: 6 (2020) and 10 (2021)

⇒ Film: 6 (2020) and 10 (2021)

⇒ Business: 8 (2020) and 10 (2021)

Formula used:

P = Difference in Hindi magazines (2021 - 2020)

Q = Difference in English magazines (2021 - 2020)

Ratio = P ∶ Q

Calculations:

P = (28 - 20) + (6 - 4) + (12 - 8) + (6 - 4)

⇒ P = 8 + 2 + 4 + 2 = 16

Q = (30 - 24) + (10 - 6) + (10 - 6) + (10 - 8)

⇒ Q = 6 + 4 + 4 + 2 = 16

Ratio P ∶ Q = 16 ∶ 16

⇒ P ∶ Q = 1 ∶ 1

∴ The ratio P ∶ Q is 1 ∶ 1.

Given:

Readership data for categories General, Sports, Film, and Business in 2020 and 2021.

Formula used:

Compare readership in 2021 with 2020 for each category to identify a decline.

Calculation:

General: 2020 (E: 2.0, H: 2.4) → 2021 (E: 2.6, H: 3.2)

⇒ Increase in both English and Hindi

Sports: 2020 (E: 0.8, H: 0.4) → 2021 (E: 1.2, H: 0.8)

⇒ Increase in both English and Hindi

Film: 2020 (E: 1.2, H: 1.6) → 2021 (E: 1.9, H: 2.5)

⇒ Increase in both English and Hindi

Business: 2020 (E: 0.6, H: 0.3) → 2021 (E: 0.8, H: 0.32)

⇒ Increase in both English and Hindi

∴ None of the above saw a decline in Hindi readership in 2021 compared to 2020.

NOTE:

Upon reviewing the readership data for all categories in Table 1, it is confirmed that each category experienced an increase in readership in 2021 compared to 2020. Therefore, none of the provided options accurately represents a category with a decline in readership. Ensure to cross-check values carefully in such questions to avoid confusion.

Given:

Total Readership in 2022 = 17.7 lakh

Total Magazines Published in 2022 = 130

Calculations:

Average Readership per Magazine = Total Readership / Total Magazines

⇒ Average = 17.7 lakh / 130

⇒ Average = 0.13615 lakh

Convert to Readers:

⇒ 0.13615 lakh = 0.13615 × 100,000 = 13,615 readers

∴ The approximate average readership per magazine in 2022 is 13,615 readers.

The logic followed here is:

Hence, "Option 1" is the correct answer.

Given:

Initial men = 45

Time taken by 45 men to complete the job = 16 days

After 6 days, 30 more men joined.

Formula used:

Work done = Men × Days

Remaining work = Total work - Work done in 6 days

New number of men = Initial men + Additional men

Calculations:

Work done by 45 men in 16 days = 45 × 16 = 720 man-days

Work done in 6 days by 45 men = 45 × 6 = 270 man-days

Remaining work = 720 - 270 = 450 man-days

New number of men = 45 + 30 = 75 men

Time taken to complete remaining work = 6 days

∴ They will take 6 days to complete the remaining work.

Shortcut Trick

Interest in 3/2 years = 1164 - 1008 = Rs. 156

So, Interest in 1 year = 156 × 2/3 = Rs. 104

and, Interest in 2 years = 2 × 104 = Rs. 208

So, amount deposited (P) = A - SI = 1008 - 208 = Rs. 800

Now,

Rs. 104 is the interest in 1 year on the principle of Rs. 800

So, rate = 104/800 × 100 = 104/8 = 13%

Hence, ₹800, 13% is the correct answer.

Alternate Method

Given:

Amount after 2 years = ₹1008

Amount after 3.5 years = ₹1164

Formula used:

Amount = Principal + Simple Interest

Simple Interest (SI) = (P × R × T) / 100

Calculations:

Let Principal = P and Rate of interest = R%

Step 1: For 2 years:

Amount after 2 years = ₹1008

Formula: 1008 = P + (P × R × 2) / 100

⇒ 1008 = P(1 + 2R / 100)

⇒ 1008 = P(1 + 0.02R)

Step 2: For 3.5 years:

Amount after 3.5 years = ₹1164

Formula: 1164 = P + (P × R × 3.5) / 100

⇒ 1164 = P(1 + 3.5R / 100)

⇒ 1164 = P(1 + 0.035R)

Step 3: Divide the two equations:

1164 / 1008 = (1 + 0.035R) / (1 + 0.02R)

⇒ 1.1548 = (1 + 0.035R) / (1 + 0.02R)

Cross multiply and simplify:

⇒ 1.1548 × (1 + 0.02R) = 1 + 0.035R

⇒ 1.1548 + 0.023096R = 1 + 0.035R

⇒ 0.1548 = 0.011904R

⇒ R = 0.1548 / 0.011904 = 13%

Step 4: Substitute R = 13 in the first equation:

1008 = P(1 + (2 × 13) / 100)

⇒ 1008 = P(1 + 0.26)

⇒ 1008 = P(1.26)

⇒ P = 1008 / 1.26 = ₹800

∴ The principal amount deposited is ₹800 and the rate of interest is 13% per annum.

• Option 1 is incorrect because it mentions only gold and treasure, ignoring the other economic motives listed in the passage.
• Option 2 is incorrect because it mentions only salt and metals, ignoring the other economic motives listed in the passage.
• Option 3 is incorrect because it mentions only trade routes, ignoring the other economic motives listed in the passage.

The correct answer is Option 1.

 

Key Points

• The passage mentions that warfare is "extremely diverse and historically widespread."
• Simple remedies are insufficient to address the complexities of war because of its diverse nature and historical breadth.
• Economic, ideological, religious motives, and the quest for security contribute to the persistence of war.
• Other options do not accurately reflect the reasons given in the passage for the difficulty in eradicating war.

Therefore, the correct answer is Option 1.

 

Additional Information

• Option 2: Incorrect because the passage does not claim that understanding people and society is easy or relevant to the difficulty of eradicating war.
• Option 3: Incorrect because modern technology is not cited as a primary reason for the difficulty in eradicating war, though cyber-attacks are mentioned as a new form of conflict.
• Option 4: Incorrect because wealthy people are not indicated as a primary reason for the persistence of war in the passage.
