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

Formula used:

Ratio of demand for two commodities = (Higher demand) / (Lower demand)

Calculation:

Foodgrains to Milk = 350.0 / 287.5 ≈ 1.22

Meat, Fish, and Eggs to Sugar = 28.3 / 23.1 ≈ 1.22

Milk to Vegetables = 287.5 / 170.2 ≈ 1.69

Meat, Fish, and Eggs to Edible oil = 28.3 / 14.3 ≈ 1.98

Highest ratio = 1.98 (Meat, Fish, and Eggs to Edible oil)

∴ The highest ratio among the given options is for Meat, Fish, and Eggs to Edible oil.

Formula used:

Growth = (Final Value - Initial Value) / Initial Value × 100%

Calculation:

Milk growth = ((287.5 - 48.8) / 48.8) × 100 ≈ 489.96%

Foodgrains growth = ((350.0 - 168.3) / 168.3) × 100 ≈ 108.01%

Meat, Fish, and Eggs growth = ((28.3 - 3.0) / 3.0) × 100 ≈ 843.33%

Sugar growth = ((23.1 - 9.6) / 9.6) × 100 ≈ 140.63%

Highest growth = 843.33% (Meat, Fish, and Eggs)

∴ The commodity with the highest growth in demand from 1990 to 2020 is Meat, Fish, and Eggs.

Calculation:

Average demand for Sugar = (9.6 +  12.8 + 18.4 + 23.1) / 4 = 63.9 / 4 = 15.975

Average demand for Edible oils = (4.3 + 6.3 + 10.1 + 14.3) / 3 = 35 / 4 = 8.75

Average demand for Fruits = (12.5 + 22.2 + 43.5 + 82.1) / 3 = 160.3 / 4 = 40.075

Average demand for Meat, Fish, and Eggs = (3.0 + 6.2 + 13.6 + 28.3) / 4 = 51.1 / 4 = 12.775

Least average demand = 8.75 (Edible oils)

∴ The commodity with the least average demand from 1990 to 2020 is Edible oils.

Formula used:

A commodity’s demand has at least doubled if:

Demand in 2020 ≥ 2 × Demand in 2010

Calculation:

Fruits: 2 × 43.5 = 87.0 (82.1 < 87.0) 

Milk: 2 × 146.2 = 292.4 (287.5 < 292.4) 

Meat, Fish, and Eggs: 2 × 13.6 = 27.2 (28.3 ≥ 27.2) 

Vegetables: 2 × 112.1 = 224.2 (170.2 < 224.2) 

∴ The commodity whose demand has at least doubled from 2010 to 2020 is Meat, Fish, and Eggs.

Formula used:

Ratio of Fruits to Vegetables = Fruits demand / Vegetables demand

Calculation:

1990: 12.5 / 56.0 ≈ 0.223

2000: 22.2 / 80.0 ≈ 0.278

2010: 43.5 / 112.1 ≈ 0.388

2020: 82.1 / 170.2 ≈ 0.482

We need to find years where the ratio is < 1/3 (≈ 0.333).

1990 (0.223) and 2000 (0.278) satisfy this condition.

∴ The correct answer is 1990 and 2000.

Given:

Original fraction = x/y

New numerator = x + 20% of x = 1.2x

New denominator = y - 20% of y = 0.8y

Value of new fraction = 6/9 = 2/3

Formula Used:

New fraction = (1.2x) / (0.8y) = 2/3

Calculations:

According to the question:

(1.2x) / (0.8y) = 2/3

1.2x × 3 = 2 × 0.8y

3.6x = 1.6y

x/y = 1.6/3.6

x/y = 4/9

∴ The fraction is 4/9

Given:

Sequence: -3/2, 3/4, 3/8, 3/16, -3/32, ...

We need to find the 11^th term of this sequence.

Formula used:

The general term of a geometric sequence is:

T_n = a × r^(n-1)

Where:

a = First term = -3/2

r = Common ratio

n = 11

Calculation:

Finding the common ratio (r):

r = (Second term) / (First term)

= (3/4) ÷ (-3/2)

= (3/4) × (-2/3)

= -1/2

Now, using the general formula:

T₁₁ = (-3/2) × (-1/2)^(11-1)

= (-3/2) × (-1/2)¹⁰

= (-3/2) × (1/1024)

= -3 / 2048

∴ The eleventh term is -3/2048.

Given:

Cost of 3 kg of potatoes and 4 kg of tomatoes = Rs. 100

Cost of 4 kg of potatoes and 3 kg of tomatoes = Rs. 110

Formulas Used:

Let the cost of potatoes per kg be P and the cost of tomatoes per kg be T.

3P + 4T = 100 → (i)

4P + 3T = 110 → (ii)

Calculations:

Multiply equation (i) by 4 and equation (ii) by 3 to eliminate P:

12P + 16T = 400 → (iii)

12P + 9T = 330 → (iv)

Subtract equation (iv) from equation (iii):

7T = 70

T = 10

∴ The rate of tomatoes per kg is Rs. 10

Given:

Principal (P) = Rs. 1024

Rate of Interest (R) = 50% per annum compounded half yearly

Time (T) = 2 years

Formula Used:

Amount (A) = P(1 + R/n)^(nT)

where P → Principal, R → Rate of Interest, n → Number of times interest applied per time period, T → Time

Calculations

Since the interest is compounded half yearly, n = 2 and R = 50% per annum = 25% per half year

Amount A = 1024(1 + 0.25)⁴

A = 1024(1.25)⁴

A = 1024 × 2.4414

A = 2500

∴ The amount he has to pay back at the end of the loan period is Rs. 2500
