Question 2

The weights of 4 boxes are 30, 20, 50 and 90 kilograms. Which of the following cannot be the total weight, in kilograms, of any combination of these boxes and in a combination a box can be used only once?

Accepted Answer

The maximum possible weight by combining all four boxes is 30 + 20 + 50 + 90 = 190 kg. Therefore, a total weight of 200 kg is impossible.

Question 3

Select the related letters from the given alternatives. FHK : DFI :: OQT : ? FHK : DFI :: OQT : ?

Accepted Answer

Each letter in the first term is shifted backward by 2 positions to get the second term (F-2=D, H-2=F, K-2=I). Applying this to OQT: O-2=M, Q-2=O, T-2=R, giving MOR.

Question 4

Who discovered television?

Accepted Answer

John Logie Baird, a Scottish engineer, invented the first working mechanical television system in 1925. He successfully demonstrated the transmission of moving silhouette images, revolutionizing communication.

Question 5

Proﬁt of Rs 1,03,500 has to be divided between three partners A, B and C in the ratio 11:7:5. How much amount (in Rs) does B get?

Accepted Answer

Total ratio parts = 11 + 7 + 5 = 23. Value of 1 part = 1,03,500 / 23 = 4,500. B's share is 7 parts, so 7 × 4,500 = 31,500 Rs.

Question 6

At which of the following place, weight of an object is maximum?

Accepted Answer

Weight depends on gravity (W=mg). Gravity is maximum at the poles because they are closer to the Earth's center due to its oblate spheroid shape, making the weight maximum there.

Question 7

Which country is the third biggest in terms of Gross Domestic Product (GDP)?

Accepted Answer

Based on the provided GDP data chart, after arranging the countries in descending order of their GDP values, country C ranks exactly third.

Question 8

What is the difference (in crores) in population of the most and the least populated country?

Accepted Answer

Identify the countries with the maximum and minimum populations from the given data chart. Subtract the lowest population from the highest to get the correct difference of 36 crores.

Question 9

According to the categories of land mentioned in the Chola inscriptions ___________ was known as the land gifted to Brahmanas?

Accepted Answer

In Chola inscriptions, 'Brahmadeya' refers to tax-free land gifted to Brahmanas. 'Vellanvagai' was for non-Brahmana peasants, 'Shalabhoga' for schools, and 'Devadana' for temples.

Question 10

What is the difference of the cube and square of the common root of (x2 – 8x + 15) = 0 and (y2 + 2y – 35) = 0?

Accepted Answer

Find the roots: x = 3, 5 and y = -7, 5. The common root is 5. The difference between its cube and square is 5³ - 5² = 125 - 25 = 100.

Question 11

There are total _________ parliamentary seats (Rajya Sabha constituency) in Punjab.

Accepted Answer

Punjab is allocated exactly 7 seats in the Rajya Sabha (the upper house of India's Parliament) and 13 seats in the Lok Sabha.

Question 12

_______ determines colour, texture, chemical properties, mineral content and permeability of soil. 9/7/2017 Staff Selection Commision

Accepted Answer

The parent rock is the original material from which soil is formed. It directly determines the soil's mineral composition, color, texture, chemical properties, and permeability.

Question 13

If α and β are roots of the equation 3x2 – 13x + 14 = 0, then what is the value of (α/β) + (β/α)?

Accepted Answer

Sum of roots α+β = 13/3, product αβ = 14/3. We need (α²+β²)/αβ = [(α+β)² - 2αβ]/αβ. Substituting values gives [(169/9) - (28/3)] / (14/3) = (85/9) / (14/3) = 85/42.

Question 14

If 17@1=8; 9@1=4; 6@4=1; then what is the value of 8@2=?

Accepted Answer

The logic is (A - B) / 2. For 8@2, subtract 2 from 8 to get 6, then divide by 2 to get 3.

Question 15

What is the fourth proportional to 336, 288 and 161?

Accepted Answer

Let the fourth proportional be x. Then 336/288 = 161/x. Solving this gives x = (288 × 161) / 336. Simplifying the fraction yields x = 6 × 23 = 138.

Question 16

If 2 cos θ = 2 – sin θ, then what is the value of cos θ?

Accepted Answer

Square both sides: 4 cos²θ = 4 - 4 sinθ + sin²θ. Substitute cos²θ = 1 - sin²θ. Solving gives 5 sin²θ - 4 sinθ = 0, so sinθ = 0 or 4/5. Thus, cosθ = 1 or 3/5.

Question 17

A multicellular organism grows by ____________.

Accepted Answer

Multicellular organisms grow through cell division (mitosis), where a single cell divides to form new cells, thereby increasing the total number of cells in the body.

Question 18

Prince Salim was the name of the future Emperor _________.

Accepted Answer

Prince Salim was the eldest son of Emperor Akbar. Upon ascending the Mughal throne in 1605, he adopted the title Jahangir, meaning 'Conqueror of the World'.

Question 20

If the ___________ ﬁrm has zero costs or only has ﬁxed cost, the quantity supplied in equilibrium is given by the point where the average revenue is zero.

Accepted Answer

In perfect competition, Price = Average Revenue (AR) = Marginal Cost (MC). If marginal costs are zero, the equilibrium quantity is supplied where AR is also zero.
