UGC NET Paper 1: Held on 16th Jan 2025 Shift 1 (Previous Year Paper)

Calculation:

 

Let number of males selected for Interview = x

Since ratio is 1 : 2,

x : 460 = 1: 2

⇒ x = \(\frac{460}{2}\) = 230

Percentage of males selected for Interview = \(\frac{230}{2000} \times 100\)

⇒ \(\frac{23000}{2000}\) = 11.5%

Percentage of females selected for Interview = \(\frac{460}{8000} \times 100\)

⇒ \(\frac{46000}{8000}\) = 5.75%

Required percentage = \(\frac{(11.5 - 5.75)}{5.75} \times 100\)

⇒ \(\frac{5.75}{5.75} \times 100\) = 100%

∴ The percentage of males selected for Interview is 100% more than that of females.

Formula used:

Percentage required = \(\frac{\text{Number of females selected}}{\text{Number of males selected}} \times 100\)

Calculation:

 

⇒ Number of males selected for Interview = \(\frac{15 \times 3600}{100}\)

⇒ \(\frac{54000}{100}\) = 540

⇒ Required percentage = \(\frac{351}{540} \times 100\)

⇒ \(\frac{35100}{540}\) = 65%

∴ The number of female students selected to appear for Interview is 65% of the number of male students selected to appear for Interview.

Calculation:

 

⇒ Number of females selected after Interview = \(\frac{3600}{100}\) = 36

⇒ Total students selected after Interview = \(\frac{36 \times 100}{40}\)

⇒ \(\frac{3600}{40}\) = 90

∴ The total number of students selected after Interview from City E is 90.

Calculation:

 

⇒ Number of students who appeared for Interview from city C = \(\frac{35}{8 \times 100}\) × 16000 = 700

⇒ Number of males who appeared for Interview from city C = 700 - 300 = 400

⇒ Required percentage = \(\frac{400}{50000} × 100\)

⇒ 0.8%

∴ The number of male students who appeared for Interview from City C is 0.8% of the number of male students who appeared in Exam-1 from City C.

Calculation:

 

Count the number of cities where the number of females who appeared in Exam-1 is more than 4,000.

Cities with more than 4,000 females appearing in Exam-1:

City A (4,200)

City B (8,000)

City C (30,000)

City D (70,000)

Number of such cities = 4

∴ The number of cities where the number of females who appeared in Exam-1 is more than 4,000 is 4.

The correct answer is - 11 and 11

Key Points

• Understanding the IF Function
• The IF function in Excel evaluates a condition and returns one value if true, and another value if false.
• Nested IF Functions
• The function used is a nested IF function, meaning one IF function is placed inside another.
• This allows for multiple conditions to be evaluated sequentially.
• Evaluating the Conditions
• First condition: A1 > B1 returns 1.
• Second condition: A1 = 10 returns 2.
• Third condition: A1 < B1 returns 3.
• If none of the above conditions are true, it returns 4.
• Final Evaluation
• If A1 = 11 and B1 = 11, none of the conditions (A1 > B1, A1 = 10, A1 < B1) are met.
• Therefore, the function returns the final value, which is 4.

Additional Information

• IF Function Syntax
• The basic syntax of the IF function is: =IF(condition, value_if_true, value_if_false)
• It is used to make logical comparisons between a value and what the user expects.
• Logical Operators

Given:

The speed of an electric train is 25% more than that of a steam engine train.

The steam engine train takes 4 hours 25 minutes to cover a certain distance.

Formula Used:

Speed = Distance / Time

Time = Distance / Speed

Calculations:

Let the speed of the steam engine train be "S".

Then, the speed of the electric train is 1.25 times "S" (since it is 25% more).

Time taken by the steam engine train to cover the distance = 4 hours 25 minutes = 4 + 25/60 = 4 + 5/12 = 53/12 hours

Let "D" be the distance covered.

For the steam engine train: D = S × 53/12

For the electric train: D = 1.25S × Time

Since the distance covered is the same, we can equate the two distances:

S × 53/12 = 1.25S × Time

53/12 = 1.25 × Time

Time = 53/12 × 1/1.25 = 53/12 × 4/5 = 53/15 = \(\rm 3\frac{8}{15}\ hr\)

∴ Time taken by the electric train to cover the distance is \(\rm 3\frac{8}{15}\ hr\).

The correct answer is - Accent

Key Points

Given:

We need to match LIST-I with LIST-II.

Calculations:

A. Median of 4, 4, 5, 7, 6, 7, 7, 12, 3

Arranging in ascending order: 3, 4, 4, 5, 6, 7, 7, 7, 12

Median = Middle value = 6

So, A → III

B. Mean of 7, 5, 9, 8, 15, 3, 8, 9

Mean = (Sum of values) / (Number of values)

= (7 + 5 + 9 + 8 + 15 + 3 + 8 + 9) / 8

= 64 / 8

= 8

So, B → IV

C. Mode of 2, 3, 7, 1, 3, 2, 3

Mode = Most frequent number = 3

So, C → I

D. Value of x, if mean of x, x+2, x+4, x+6, x+8 is 11

Mean = (x + (x+2) + (x+4) + (x+6) + (x+8)) / 5

11 = (5x + 20) / 5

55 = 5x + 20

5x = 35

x = 7

So, D → II

Final Matching:

A → III (6)

B → IV (8)

The correct answer is - A universal proposition of which only the subject is distributed

Key Points

• Visamvyapti
• Refers to a universal proposition where the subject is distributed, but the predicate is not.
• In logic, distribution means that a term refers to all members of the category it denotes.
• Example: In the statement "All dogs are mammals," "dogs" is distributed because it refers to all dogs, but "mammals" is not distributed because not all mammals are dogs.

Additional Information

• Propositions in Logic
• Universal Propositions
• Statements that assert something about all members of a category.
• Examples include "All A are B" and "No A are B."
• Particular Propositions
• Statements that assert something about some members of a category.
• Examples include "Some A are B" and "Some A are not B."
• Distribution of Terms
• A term is distributed if the proposition makes an assertion about every member of the category denoted by the term.
• In universal affirmative propositions (A propositions), the subject is distributed, but the predicate is not.
• In universal negative propositions (E propositions), both the subject and predicate are distributed.
• In particular affirmative propositions (I propositions), neither the subject nor predicate is distributed.
• In particular negative propositions (O propositions), the predicate is distributed, but the subject is not.

Given:

Six numbers a, b, c, d, e, f are such that ab = 1, bc = 1/2, cd = 6, de = 2, and ef = 1/2.

Calculations:

ad = abcd / bc

⇒ (1 × 6) / (1 / 2) = 12

be = bcde / cd

⇒ [(1 / 2) × 2 ] / 6 = 1 / 6

cf = cdef / de

⇒ ( 6 × 1 / 2 ) / 2 = 3 / 2

Now the required ratio :

(ad ∶ be ∶ cf) = ( 12 : \(\frac{1}{6}\) : \(\frac{3}{2}\) ) × 6

⇒ 72 : 1 : 9

∴ The correct answer is 72 : 1 : 9.

Given:

Two cylindrical jars have their diameters in the ratio 3 ∶ 1 and heights in the ratio 1 ∶ 3.

Formula Used:

Volume of a cylinder = πr²h

where r = radius, h = height

Calculations:

Let the diameter of the first jar be 3d and the diameter of the second jar be d. Hence, the radii will be 3d/2 and d/2 respectively.

Let the height of the first jar be h and the height of the second jar be 3h.

The volume of the first jar = π(3d/2)²h = π(9d²/4)h = (9πd²h)/4

The volume of the second jar = π(d/2)²3h = π(d²/4)3h = (3πd²h)/4

∴ The ratio of their volumes = (9πd²h)/4 : (3πd²h)/4 = 9 : 3 = 3 : 1
