The correct answer is If the market of a particular commodity consists of more than one seller, but the number of sellers is few, the market structure has termed an oligopoly.

Key Points

• A market with an oligopoly has a small number of businesses that are aware of their interdependence in terms of price and production strategies.
• Each company has a certain amount of market power due to the small number of enterprises.
• Oligopoly differs from perfect competition in that each firm must consider its interconnectedness, from monopolistic competition in that firms have some control over pricing, and from monopoly, in that, a monopolist has no competitors.
• The implications of mutual dependency among firms in pricing and output decisions are generally the focus of oligopoly study.​

Additional Information

• A market with a monopoly has just one producer, a duopoly has two businesses, and an oligopoly has three or more businesses.
• A monopoly is a market system where there is only one seller and there are enough barriers to entry for any other sellers.

The correct answer is Tamil Nadu​.

Key Points

• Kanyakumari is located at the southern tip of the Cardamom Hills in Tamil Nadu.
• Cape means the land infiltrated into the sea and Comorin is the former ame of the Kanyakumari.
• During the British Rule, sailors and traders used the word Cape to mention the identical landmark of Comorin.

Important Points

• The north-south extent from Indira Col in Kashmir to Kanyakumari is 3,214 km.
• The east-west width from the Rann of Kutch to Arunachal Pradesh is 2,933 km.
• With an area of 32,87,263 sq km, India is the seventh-largest country in the world.
• India accounts for about 2.4 per cent of the total surface area of the world.

Additional Information

• Extreme points of India:

Given:

15, 2, 7, 8, 11, 5 and 14

Concept used:

Median is defined as the middle value of a sorted list of numbers.

Calculation:

The distribution in sorted form,

2, 5, 7, 8, 11, 14, 15.

Now, the median of the distribution = 8

∴ 8 is the median of 15, 2, 7, 8, 11, 5, and 14.

The correct answer is Net Worth = Assets - Liabilities.

Key Points

• The book value of the equity held by shareholders of a corporation is referred to as "Net worth."
• It can also be thought of as the net worth of a corporation that its shareholders would be able to claim in the event that all of its assets were liquidated and all of its obligations were paid off.
• To put it another way, it is the sum of assets that remain after all liabilities have been settled.
• Stockholder's equity and shareholder's equity are other names for a company's net worth.
• By deducting the subject company's total liabilities from its total assets, one can arrive at the formula for net worth.

Important Points

• Although equity and net worth are sometimes used interchangeably, they are occasionally employed in different circumstances.
• The net worth calculation takes into account both assets and liabilities.
• The following are the two things to keep in mind when thinking about net worth:
  • If net worth is more than zero, it can pay off debt and has strong financial growth.
  • If net worth is zero, the company cannot pay its debts and has negative financial growth.

Given:

Rate of interest = 60%

Time (n) = 2 years

Interest = ₹11,700

Concept used:

Compound interest, CI = P(1 + R/100)ⁿ - P

where

P = Principal amount

R = Rate of interest per year

N = Time in years

Calculation:

Let the initial investment (Principal amount) be P.

According to the question,

P(1 + 60/100)² - P= 11700

⇒ P × 1.6² - P = 11700

⇒ P × 2.56 - P = 11700

⇒ P (2.56 - 1) = 11700

⇒ P × 1.56 = 11700

⇒ P = 11700/1.56

⇒ P = 7500

∴ He initially invested ₹7,500.

The correct answer is income effect.

Key Points

• The change in demand for a commodity or service brought on by a shift in a consumer's purchasing power as a result of a change in real income is known as the income effect in microeconomics.
• This adjustment may be brought about by an increase in salaries, for example, or by the release of funds from an existing income due to a drop in the cost of the item being purchased.
• The income effect is an expression of how changes in relative market prices and incomes impact consumption patterns for consumer goods and services.
• Consumer choice theory links preferences to consumption expenditures and consumer demand curves.
• When real consumer income increases, consumers will desire more of the typical economic items to buy.

Important Points

• The substitution effect is the decline in sales of a product that results from customers switching to less expensive substitutes when the price of the product increases.
• The change in output that results from using one extra unit of a certain input, given that the quantities of other inputs are held constant, is known as the marginal product or marginal physical productivity of an input (factor of production).
• The set of all conceivable consumption bundles that a customer may afford, given the prices of the commodities they have access to and their income, is known in economics as a budget set or the opportunity set facing a consumer.

The correct answer is Madhya Pradesh.

Key Points

• The total forest cover of MP is 77,414 sq km.
• In terms of area, Madhya Pradesh has the largest forest cover in the country followed by Arunachal Pradesh, Chhattisgarh, Odisha, and Maharashtra.

Additional Information

• In terms of forest cover as a percentage of their total geographical area, the top five states are
  • Mizoram (85.41 per cent)
  • Arunachal Pradesh (79.63 per cent)
  • Meghalaya (76.33 per cent)
  • Manipur (75.46 per cent)
  • Nagaland (75.31 per cent).

The least possible Venn diagram is:

Conclusions:

I. Some goods are costly. → False (it is possible but not definite)

II. All costly are beautiful. → False (it is possible but not definite)

Hence, neither conclusion I nor conclusion II follows.

The correct answer is Ranchi.

Key Points

• The ninth edition of the National Open Race Walking Championships, a qualifying event for the 2022 year’s World Championships, was held in Ranchi, Jharkhand.
• The championships will have 35km and 20km race walk events for men and 20km events for women.

Given:

The length and the width of a rectangular plot of land are 10.5 m and 8 m, respectively.

Concept used:

Area of a rectangle = Length × Width

Calculation:

Area of the rectangular plot = 10.5 × 8 = 84 m²

Cost of laying grass in the entire plot

⇒ 84 × 15.25

⇒ ₹1,281

∴ The cost of grass in the entire plot is ₹1,281.

Statement:

W = H ≤ G < C ≥ T = L > M

Conclusions:

I. W < T → False (As W = H ≤ G < C ≥ T → a definite relation between W and T cannot be determined)

II. C > M → True (As C ≥ T = L > M → C > M)

Hence, only conclusion II is true.

Given:

The price of item A was 2/3 of the price of item B, while the price of item C was  3/4 of the price of item B.

The price of item A was ₹88

Calculation:

Let the price of item B be Q.

The price of item A = 2Q/3

The price of item C = 3Q/4

According to the question,

2Q/3 = 88

⇒ Q = (88 × 3)/2

⇒ Q = 132

Now,

3Q/4 = (3 × 132)/4

⇒ 99

∴ The price of item C was ₹99.

The correct answer is It requires decreasing inputs over time.

Key Points

• The introduction of new, high-yielding varieties into emerging countries starting in the middle of the 20th century, led to a significant increase in the production of food grains (particularly wheat and rice).
• Mexico and the Indian subcontinent saw their first stunning successes.
• In order to achieve their high yields, the new types need to use significant quantities of chemical fertilisers and pesticides, which raises concerns about the expense and potential negative impacts on the environment.

Important Points

• The collection of research and technology transfer programmes known as the "Green Revolution" took place between 1950 and the late 1960s and significantly enhanced agricultural production throughout much of the world.
• High-yielding varieties (HYVs) of cereals, particularly dwarf wheat and rice, were adopted as a result of the initiatives.
• It was connected to mechanised farming, artificial fertilisers, agrochemicals, controlled water supply (typically using irrigation), and innovative farming techniques.
• These were all considered to be part of a "bundle of activities" that would replace "conventional" technology and be adopted as a whole.

Given:

5 is added to one-third of the number, the sum is 59.

Calculation:

Let the number be Q.

One-third of Q = Q/3

According to the question,

5 + Q/3 = 59

⇒ Q/3 = 59 - 5

⇒ Q/3 = 54

⇒ Q = 54 × 3

⇒ Q = 162

∴ The number is 162.

The correct answer is SoftWorthy.

Key Points

The logic followed here is:

Similarly,

Hence, ‘EGLTDR’ is the correct answer.

Concept used:

If the sum of digits of the number is divisible by 9, then the number itself is divisible by 9.

Calculation:

We'll be considering the options one by one,

Option A ,

The sum of the digits of 45390

⇒ 4 + 5 + 3 + 9 + 0

⇒ 21

⇒ Not a multiple of 9

Now since we've already encountered a number that is not divisible by 9 among the four options, there is no need to check any further.

∴ 45390 is not divisible by 9.

There are six girls Mayuri, Kavyanjali, Divya, Poonam, Neha and Vidya.

Each girl likes a different colour - red, blue, purple, yellow, green and pink.

1. Divya likes red colour.

2. Poonam does not like green and yellow colour.

3. Neha likes purple colour.

4. Vidya does not like pink and green colour.

5. Mayuri likes blue colour.

It is clear that Kavyanjali likes Green colour as there is no vacant position left for Green.

Vidya likes Yellow and Poonam likes Pink Colour as these are the only vacant positions left for Yellow and Pink.

1. Kavyanjali - Pink → Incorrect

2. Neha - blue → Incorrect

3. Vidya - yellow → Correct

4. Poonam - green → Incorrect

Clearly, 'Vidya - yellow' combination is correct.

Hence, ‘Vidya - yellow’ is the correct answer.

Given:

A conical tent with a base diameter of 10 m and a height of 12 m has been made.

An additional 10% cloth is required as wastage in stitching the tent.

Concept used:

Curved surface area = πrl

where r = radius of the base and l = slant height

Slant height, L =

where R = radius of the base, H = Height

The area of the cloth needed to make the conical tent is equal to the curved surface area of the conical tent.

Calculation:

Radius of the base = 10/2 = 5m

Slant height of the tent

⇒

⇒ 13m

Total curved surface area of the conical tent

⇒ π × 5 × 13

⇒ 65π m2

Now, the area of the cloth required

⇒ 65π + 65π × 10%

⇒ 65π + 6.5π

⇒ 71.5π m²

∴ The area of the cloth required is 71.5π m2.

Six friends - Sheela, Roma, Sheetal, Sreeja, Naina and Rahul are sitting on a bench facing north.

1. Sreeja and Rahul are sitting at the 3rd and 4th positions respectively from the left end.

2. Sheela and Naina are sitting at the extreme right and left ends, respectively.

3. Sheela is sitting to the immediate right of Roma.

Clearly, only one position is left and Sheetal is the only person left, so the vacant position will be occupied by Sheetal.

Therefore, the arrangement will be as shown below:

Sheetal is sitting immediately next to Naina.
Hence, ‘Sheetal’ is the correct answer.

The correct answer is Brazil.

• Santos Port also known as the 'coffee port' of the world is located in Brazil.

Key Points

• Brazil is the top coffee-producing country accounting for 40 percent of the global coffee supply.
• Vietnam is the second-largest coffee producer, accounting for roughly 20 percent of the world's coffee production.
• Quality-wise, Ethiopian coffee is considered the world's best coffee.

Important Points

• The motherland of coffee - Ethiopian Highland (Africa).
• Santos Port in Brazil is also known as a Coffee port.

Additional Information

• In India, the first plant of coffee was planted in Baba Budan Hills, Karnataka.

Eight friends - Janaki, Komali, Lokesh, Manu, Nirvan, Rajan, Paru and Silpa, are sitting around a square table in such a way that four of them sit at four corners while four sit in the middle of each of the four sides.

The ones who sit in the middle of the sides face the centre, while those who sit at the four corners face outward (i.e. opposite the centre).

1. Lokesh sits third to the right of Manu.

2. Manu sits in the middle of one of the sides of the table.

3. Exactly three people sit between Lokesh and Silpa.

4. Paru sits second to the right of Silpa.

5. Nirvan is one of the immediate neighbours of Paru.

6. Exactly three people sit between Nirvan and Komali.

The above condition cannot be satisfied in Case I, so it is eliminated.

7. Janaki sits second to the right of Komali.

Only one person Rajan and one position is vacant, so Rajan will occupy the vacant position.

So, the final arrangement will be as shown below:

1. Nirvan sits second to the left of Rajan → False (Lokesh sits second to the left of Rajan)

2. Both Manu and Komali are immediate neighbours of Rajan → True

3. Only three people sit between Rajan and Janaki → False (Either two or four people sit between Rajan and Janaki when counted from the left of Rajan and right of Rajan respectively)

4. Rajan sits in the middle of one of the sides → False (Rajan sits at one of the corners)
Hence, 'Both Manu and Komali are immediate neighbours of Rajan' is the correct answer.

The correct answer is Tejus Chauhan.

  • Headquarters - Paris, France.
  • Secretary-General - John W.H. Denton AO

The correct answer is Ghrelin.

Key Points

• Small amounts of ghrelin are also released by the small intestine, pancreas, and brain.
• Ghrelin is primarily synthesised and released by the stomach.
• Ghrelin serves a variety of purposes. Because it stimulates appetite, increases food intake, and encourages fat storage, it is known as the "hunger hormone."
• Ghrelin circulates in the bloodstream and works in the hypothalamus, a region of the brain important in the regulation of appetite, increasing food intake in humans by up to 30%.​

Important Points

• The INS gene in humans encodes insulin, a peptide hormone generated by beta cells of the pancreatic islets.
  • It is regarded as the body's primary anabolic hormone.
• Resistin is a cysteine-rich peptide hormone produced by adipose tissue and is encoded by the RETN gene in humans.
  • Other names for resistin include adipose tissue-specific secretory factor (ADSF) and C/EBP-epsilon-regulated myeloid-specific secreted cysteine-rich protein (XCP1).
• Leptin is a hormone primarily produced by enterocytes and adipocytes in the small intestine.
  • It inhibits appetite, which in turn reduces fat storage in adipocytes and aids in the regulation of energy balance.

The pattern followed here is: Vowels with the highest place value are arranged first and then consonants with the highest place value are arranged

According to the alphabetical positions of the letters,

'COUSIN' is written as 'UOISNC' → Vowels with the highest place value are arranged first and then consonants with the highest place value are arranged to get the code for the word COUSIN.

'AUNTY' is written as 'UAYTN' → Vowels with the highest place value are arranged first and then consonants with the highest place value are arranged to get the code for the word AUNTY.

Similarly,

'UNCLE' will be coded as 'UENLC'.

Hence, ‘UENLC’ is the correct answer.

Statement: One must wake up early in the morning and exercise.

Assumption I: Exercising is not possible at any other time of the day.

This assumption extends beyond what the statement says. The statement merely emphasizes the importance of waking up early to exercise, but it doesn't rule out the possibility of exercising at other times of the day.

Assumption II: Everyone who exercises early in the morning is fitter than those who do not.

This assumption introduces an unwarranted comparison of fitness levels based on the timing of exercise, which is not mentioned or implied in the statement. The statement does not comment on the fitness outcomes relative to the timing of exercise.

Given that neither of these assumptions is directly supported or implied by the statement, the correct answer is:

Neither assumption I nor assumption II is implicit.

Alternate Method

The statement tells us that it is a must to wake up early and exercise in the morning.

However, this statement does not imply that it is not possible to exercise at other times. Therefore, assumption I is not implicit.

The statement does not give any information at all about the effect of early morning exercises. Therefore, assumption II is not implicit.

Hence, neither assumption I nor assumption II is implicit.

The correct answer is E-100.

Key Points

  • World environment day is celebrated to encourage awareness and action for the protection of the environment.
  • It is celebrated on 5th June every year.
  • First held in 1974.
  • The theme of first-world environment day was "only one earth".
  • The theme for World Environment Day 2022 is Only One Earth.
  • The host country is Sweden.

Calculation:

Cases reported in state C = 12%

Cases reported in state F = 30%

Cases reported in state C and F together = 12 + 30 = 42%

Let the entire pie chart be 100%

The crime cases in state A (14% in the pie chart) were 672 in that year.

Now, 1% of the pie chart represents = 672/14 = 48 number of cases

Now, the number of cases reported in state C and state F together

⇒ 42 × 48

⇒ 2016

∴ The number of cases reported in state C and state F together was 2016.
