UGC NET Paper 1: Held on 9th Jan 2025 Shift 2 (Previous Year Paper)

Percentage of employees in sales department = 16%

Given that the number of employees in Sales department increases by 25%

So, the new percentage of employees in sales department = 16% + 25% of 16% = 20%

Percentage of employees in marketing department = 14%

given that the total number of employees in the marketing department = 560

14% = 560

1% = 560/14 = 40

So, the number of employee in sales department next year = 20% = 20 × 40 = 800

Given that the total number of employees in the marketing department = 560

14 % = 560 employee

1% = 560/14 = 40 employee

Total number of employee in IT department = 8% = 8 × 40 = 320

with increase of 60%, total number of employees in IT = 320 + 60% of 320 = 320 + 192 = 512

With increase of 20%, total number of employees in marketing = 560 + 20% of 560 = 560 + 112 = 672

Ratio of number of employees in IT and Marketing departments in the next year = 512 : 672 = 16 : 21

Given that the total number of employees in the marketing department = 560

14 % = 560 employee

1% = 560/14 = 40 employee

total number of employees in Accounts = 18% = 18 × 40 = 720

total number of employees in HR = 12% = 12 × 40 = 480

total number of employees in Production = 32% = 32 × 40 = 1280

Average = (560 + 720 + 480 + 1280)/4 = 3040/4 = 760

Given that the total number of employees in the marketing department = 560

14 % = 560 employee

1% = 560/14 = 40 employee

total number of employees in HR = 12% = 12 × 40 = 480

total number of employees in Production = 32% = 32 × 40 = 1280

Required percentage = \(\frac{1280 - 480}{1280}\times100 = \frac{800}{1280}\times 100\) = 62.5%

Given that the total number of employees in the marketing department = 560

14 % = 560 employee

1% = 560/14 = 40 employee

total number of employees in HR = 12% = 12 × 40 = 480

total number of employees in Accounts = 18% = 18 × 40 = 720

Ratio of male and female = 5 : 4

Number of male employees in Accounts = 5/9 × 720 = 400

Number of female employee in Accounts = 4/9 × 720 = 320

Total number of employees in HR = 12% = 12 × 40 = 480

60% of the employees in the HR department are females = 60% of 480 = 288

So, the number of male employees in the HR department = 480 - 288 = 192

Total number of male employees in Accounts and HR departments together = 400 + 192 = 592

The logic follows here:

Sum of position value of letters × 2 = coded letter.

Given:

'AC' is coded as 8

⇒ {A(1) + C(3)} × 2 = (1 + 3) × 2 = 4 × 2 = 8

And,

'PQ' as 33.

⇒ {P(16) + Q(17)} × 2 = (16 + 17) × 2 = 33 × 2 = 66

Similarly,

'XZ' will be coded as

Given:

Man's work days = 10 days

Man + Boy's work days = 8 days

Formula used:

Efficiency = Total work / Time

Calculations:

LCM(10, 8) = 40 (Total work)

Man's efficiency = 40 / 10 = 4 units/day

Man + Boy's efficiency = 40 / 8 = 5 units/day

Boy's efficiency = (Man + Boy)'s efficiency - Man's efficiency

⇒ Boy's efficiency = 5 - 4 = 1 unit/day

Ratio of efficiencies (Man : Boy) = 4 : 1

∴ The ratio of efficiencies of the man and the boy is 4 : 1.

Given:

Two successive discounts = 15%, 10%

Formula used:

Single discount = x + y - \(\dfrac{xy}{100}\) (where, x and y are successive discounts)

Calculations:

Single discount = 15 + 10 - \(\dfrac{(-15)(-10)}{100}\)

= 25 - \(\dfrac{3}{2}\)

= 25 - 1.5

= 23.5%

∴ The answer is 23.5%

The correct answer is 'Movement and cracking of water-saturated soil'.

Key Points

• The passage mentions that cities built on soft ground or loosely consolidated soil usually suffer great damage from earthquakes.
• It specifically states that water-saturated soil can liquefy when shaken during an earthquake.
• Under such conditions, buildings often sink or collapse, like rows of dominoes.
• The liquefaction of water-saturated soil leads to the buildings losing their support and sinking.
• The movement and cracking of such soil are the cause of buildings going "out of sight/sink".

Therefore, the correct answer is 'Option 3'.

Additional Information

• Option 1: The passage mentions damage from tsunamis, but it does not specifically link this to buildings sinking during an earthquake.
• Option 2: Cracking is mentioned in the context of seismic slip but not in relation to buildings sinking.
• Option 4: Soil extension is not mentioned in the passage.

The correct answer is 'Seismic slip'.

Key Points

• The passage states that when movement along faults occurs gradually and relatively smoothly, it is called creep or seismic slip.
• This type of movement is often undetectable to the casual observer because it lacks the suddenness associated with larger seismic events.
• Creep or seismic slip allows for the release of stress in a manner that does not generate significant ground shaking.
• Unlike other types of fault movements, seismic slip moves slowly and steadily over time.
• This gradual movement can help reduce the buildup of stress along a fault, potentially preventing larger, more destructive earthquakes.
• Seismic slip can maintain the integrity of the fault by allowing rocks to move without the friction that typically causes stress buildup.

Therefore, the correct answer is 'Option 3'.

Additional Information

• Option 1: Seismic jerk refers to a sudden release of stress, not gradual movement.
• Option 2: The epicenter is the point on a fault where the first movement occurs during an earthquake.
• Option 4: Fault rupture refers to the breaking of a fault, not gradual movement.

The correct answer is 'Sudden movements in the earth's crust along faults'.

Key Points

• The passage mentions that earthquakes are sudden movements in the earth's crust that occur along faults (planes of weakness), where one rock mass slides past another.
• It emphasizes that these movements are the primary cause of earthquakes.
• When stress builds up due to friction preventing rocks from slipping easily, it is eventually released with a sudden jerk, leading to an earthquake.
• The passage details the process of stress accumulation and release along faults, leading to earthquakes.
• The description of faults and the movement along them indicates the significance of these geological features in causing earthquakes.
• Other causes such as volcanic eruptions or extreme weather conditions are not mentioned as primary causes in the passage.

Therefore, the correct answer is 'Option 2'.

Additional Information

• Option 1: While volcanic eruptions can cause earthquakes, they are not mentioned as the main cause in this passage.
• Option 3: Floods are not related to the geological cause of earthquakes discussed in this passage.
• Option 4: Extreme weather conditions are not linked to the cause of earthquakes in the passage.

The correct answer is 'Kobe, Japan and Mexico City'.

Key Points

• The passage specifies that cities such as Kobe, Japan or Mexico City are built partly on soft ground or loosely consolidated soil.
• This particular characteristic is responsible for the significant damage these cities suffer during earthquakes.
• Soft ground or loosely consolidated soil increases the potential for soil liquefaction when shaken.
• Soil liquefaction can cause buildings to sink or collapse, exacerbating the destruction during an earthquake.
• The mention of these two specific cities indicates their vulnerability due to the nature of the soil they are built on.
• This detail distinguishes them from the other locations mentioned, which are not highlighted for having this specific soil condition.

Therefore, the correct answer is 'Option 1'.

Additional Information

• Option 2: Indonesia and Pakistan are mentioned for their earthquake events but not for being built on soft or loosely consolidated soil.
• Option 3: Pakistan is not specifically noted for having parts built on soft or loosely consolidated soil in the passage.
• Option 4: Indonesia is not specifically noted for having parts built on soft or loosely consolidated soil in the passage.

The correct answer is 'The point on a fault where the first movement occurs'.

Key Points

• The passage defines the epicenter as the point on a fault at which the first movement occurs during an earthquake.
• This is the initial location where built-up stress is released, resulting in seismic waves.
• The epicenter is essentially the starting point of the earthquake's rupture.
• The epicenter is crucial in determining the intensity and distribution of seismic waves.
• This point affects the surrounding areas depending on the depth and magnitude of the earthquake.
• The epicenter is typically located on the surface directly above the point of origin, called the focus.

Therefore, the correct answer is 'Option 3'.

Additional Information

• Option 1: The point where the most damage occurs is usually near the epicenter but is not the definition of the epicenter.
• Option 2: The area with the highest population is irrelevant to defining the epicenter.
• Option 4: The center of a tsunami is unrelated and refers to the point of the tsunami's origin, not directly to earthquake definitions.
