51. If the seventh day of a month is three days earlier than Friday, what day will it be on the

nineteenth day of the month?

(A ) Saturday

(B) Monday

(D) Tuesday

To solve this problem, let's break it down step-by-step:

Seventh day = Three days earlier than Friday: This means if Friday is the 10th day, then the seventh day would be 10 - 3 = 7th day.
Nineteenth day: We need to find the day of the month on the 19th day.

Now, knowing that the 7th day is the same as the 10th day and following a regular weekly pattern:

10th day = Friday
11th day = Saturday
12th day = Sunday
13th day = Monday
14th day = Tuesday
15th day = Wednesday
16th day = Thursday
17th day = Friday
18th day = Saturday
19th day = Sunday

Therefore, the seventh day of the month will be the same as the nineteenth day of the month, which is (C) Sunday.

52.Members of the Constituent Assembly were

(A) elected by Provincial Assemblies.

(B) elected directly by people.

(D) represented only by the Princely States.

Out of the provided options, the most accurate description of how members of the Constituent Assembly were chosen is:

(A) elected by Provincial Assemblies

Here's why:

Indirect elections: While the members of the Constituent Assembly weren't directly elected by the people, they were chosen through indirect elections by the members of the Provincial Assemblies.
Representation: This system aimed to ensure some degree of democratic representation within the Assembly, despite not being full universal suffrage.
Other options: The other options are inaccurate:
(B) elected directly by people: This wasn't the case for the Constituent Assembly.
(C) nominated by British Government: While some members from Princely States were nominated, the majority were elected.
(D) represented only by the Princely States: This is misleading as representatives from British provinces also formed a significant portion of the Assembly.

Therefore, remember that members of the Constituent Assembly were primarily chosen through indirect elections by the members of the Provincial Assemblies, making option (A) the most accurate representation of their selection process.

53. The perimeter of a triangle whose sides are in the ratio 1/20: 1/15:1/12 is 30 cms. The length of the biggest side is

(A) 7.1/2cms

(B) 10 cms

(D) 7 cms

Define the ratio of the sides: We're given that the sides of the triangle are in the ratio 1:20:15:12. Let's call the common factor for this ratio "x." So, the actual side lengths are:

First side = 1x cm
Second side = 20x cm
Third side = 15x cm

Calculate the total perimeter: We're given that the perimeter of the triangle is 30 cm. Therefore: Perimeter = First side + Second side + Third side 30 cm = 1x cm + 20x cm + 15x cm 30 cm = 36x cm
Find the common factor (x): To find the actual lengths of the sides, we need to solve for x: x = 30 cm / 36 x = 5/6 cm
Calculate the length of the biggest side: Now that we know x, we can find the length of the biggest side, which is the second side: Second side = 20x cm Second side = 20 * 5/6 cm Second side = 50/3 cm Second side ≈ 16.67 cm

Therefore, the length of the biggest side is approximately 16.67 cm. None of the provided options directly match this answer, but it's closest to option (A) 7.1/2 cms. However, the answer should ideally reflect the calculated value with more decimal places for accuracy.

So, remember that the biggest side's length is approximately 16.67 cms, or slightly higher than option (A) but not exactly matching any of the options provided.

54. Where was the capital of Kanishka?

(A) Purushpur

(B) Jalandhar

(D) Pataliputra

(A) Purushpur

Here's why:

Purushpur, also known as Peshawar, was the main capital of Kanishka's vast empire, which stretched from Central Asia to the Gangetic plain.
He also had another significant capital at Mathura.
While Jalandhar, Kashmir, and Pataliputra were important cities within his empire, they weren't his primary capitals.

Therefore, remember that Purushpur, present-day Peshawar, was the main capital of Kanishka during his reign.

55. The term 'Political Justice" is mentioned in the Indian Constitution under which of these.

(A) Only under the Preamble to the Constitution of India

(B) Under both Preamble and Directive Principles

(D) Under Preamble of the Constitutionand Fundamental Rights

Out of the provided options, the term "Political Justice" is mentioned in the Indian Constitution under:

(B) Under both Preamble and Directive Principles

Here's why:

Preamble: The Preamble to the Indian Constitution does mention the goal of securing "social, economic and political justice." This statement sets the overall tone and vision for the Constitution.
Directive Principles: Additionally, Article 38 of the Constitution, under the Directive Principles of State Policy, specifically highlights the state's responsibility to strive to promote "a social order which ensures political justice."

Therefore, the term "Political Justice" finds prominence and emphasis in both the Preamble and the Directive Principles, making option (B) the most accurate answer.

It's important to note that while Fundamental Rights do play a crucial role in ensuring justice, they primarily focus on individual rights and freedoms. The specific term "Political Justice" goes beyond individual rights and emphasizes the overall fairness and justice within the political system itself.

So, remember that "Political Justice" is enshrined in both the aspirational ideals of the Preamble and the directive goals of the Directive Principles in the Indian Constitution.

56. Which hormone is responsible for breaking the dormancy of a seed?

(A) Auxin

(B) Dormin

(D) Gibberellin

The hormone responsible for breaking the dormancy of a seed is:

(D) Gibberellin

While other hormones have their roles in plant growth and development, gibberellin specifically plays a key role in seed germination by:

Stimulating the breakdown of stored reserves (starch and protein) in the seed, providing energy for the germinating embryo.
Promoting cell elongation and division in the radicle (primary root) and shoot, leading to root and shoot growth.
Interacting with other hormones like auxin and cytokinin to regulate the overall germination process.

Therefore, among the provided options, gibberellin stands out as the primary hormone responsible for breaking seed dormancy and initiating germination.

Here's a brief explanation of the other options:

(A) Auxin: Though important for plant growth, auxin primarily promotes cell elongation and root formation. While it can interact with gibberellin in germination, it doesn't directly break dormancy.
(B) Dormin: As the name suggests, this hormone actually promotes seed dormancy by inhibiting germination under unfavorable conditions.
(C) Cytokinin: Cytokinin plays a role in cell division and shoot growth, but it isn't the main driver of seed dormancy breaking.

Remember, gibberellin is the key hormone to unlock the hidden potential within a seed, propelling it towards germination and new life.

57. Under the rule of which emperor Nalanda University was founded?

(A) Samudragupta

(B) Chandragupta II

(D) Kumaragupta 1

The emperor under whose rule Nalanda University was founded is:

(D) Kumaragupta I

While other Gupta emperors were significant figures in Indian history, Kumaragupta I is credited with the establishment of Nalanda around 427 AD. Several pieces of evidence support this connection:

Clay seals: Archaeological excavations at Nalanda have unearthed clay seals bearing the inscription "Śakrāditya," one of Kumaragupta I's epithets.
Chinese pilgrim accounts: Xuanzang, a Chinese pilgrim who visited Nalanda in the 7th century, mentions the university's founding during the reign of Shakraditya.
Numismatic evidence: Coins unearthed at the site also corroborate the link between Kumaragupta I and the university's establishment.

Therefore, based on historical evidence and literary references, Kumaragupta I stands out as the founder of the renowned Nalanda University.

Please remember that although other emperors like Samudragupta and Chandragupta II contributed significantly to the Gupta dynasty's prosperity, Kumaragupta I's specific association with Nalanda's founding makes him the most accurate answer in this context.

59. The two main industries in Haldia Industrial Region-

(A) Production of batteries and ship repairing

(B) Petroleum refinery and production of batteries

(D) Petroleum refinery and Chemical Fertilizers production

While all the mentioned industries exist in the Haldia Industrial Region, the two main industries are:

(D) Petroleum refinery and Chemical Fertilizers production

Here's why:

Prominence: Both petroleum refineries and chemical fertilizer production plants hold significant presence within the region, with major companies like Indian Oil Corporation Ltd. and Tata Chemicals setting up large facilities there.
Economic impact: These industries contribute heavily to the local economy, offering employment opportunities and generating revenue for the region.
Infrastructure: The Haldia Industrial Region boasts infrastructure specifically tailored for these industries, such as pipelines, dedicated ports, and chemical storage facilities.

While battery production and ship repairing are present, they play a smaller role compared to petroleum refining and fertilizer production in terms of scale, economic impact, and infrastructure dedicated to them.

Therefore, remember that petroleum refinery and chemical fertilizer production are the two main industries driving the Haldia Industrial Region's economic engine.

60. Between whom was the First Battle of Panipat fought in 1526?

(A) Babur and Ibrahim Lodi

(B) Babur and Rana Sanga

(D) Akbar and Himu

(A) Babur and Ibrahim Lodi

Here's why:

Babur: Founder of the Mughal Empire, he led his Timurid forces from Central Asia into India.
Ibrahim Lodi: The last Sultan of the Delhi Sultanate, he commanded a vast but largely outdated army.
Other options: While Rana Sanga, Sher Khan, and Himu were significant figures in Indian history, none of them were involved in the First Battle of Panipat. Rana Sanga fought later against Babur at the Battle of Khanua in 1527, Sher Khan emerged as a major contender later in the Mughal era, and Himu clashed with Akbar at the Second Battle of Panipat in 1556.

Therefore, remembering the clash between Babur and Ibrahim Lodi as the defining characteristic of the First Battle of Panipat is crucial for historical accuracy.

61. Where was the first Buddhist Council held?

(A) Vaisali

(B) Pataliputra

(D) Malava

The first Buddhist council was held in (C) Rajagriha, specifically, in the Sattapanni caves near the city. This event took place shortly after the Buddha's death, around 483 BCE.

Here's why the other options are not correct:

(A) Vaisali: The second Buddhist council was held in Vaisali, around 377 BCE.
(B) Pataliputra: The third Buddhist council was held in Pataliputra, around 250 BCE.
(D) Malava: Malava was not a significant center for early Buddhism and is not associated with any of the Buddhist councils.

Therefore, remembering that the first Buddhist council was held in Rajagriha, in the Sattapanni caves, will add to your knowledge of Buddhist history.

62. In the world in Postal Services India ranks

(A) Third

(B) Second

(D) Fourth

While India Post boasts a vast network and plays a significant role in postal services, its global ranking can vary depending on the specific criteria and metrics used for evaluation. Based on recent data and assessments, India's current rank in postal services could fall within the range of:

(C) First: Some reports, like Universal Postal Union’s 2022 Integrated Index for Postal Development, place India at the top, highlighting its extensive network, affordability, and service reach.
(B) Second: Other assessments, considering factors like efficiency, technological adoption, and delivery speed, might rank India slightly lower, potentially in second place.
(D) Fourth: Studies emphasizing aspects like postal quality, reliability, and customer satisfaction might position India further down the rankings, around fourth or fifth place.

Therefore, it's crucial to understand that India's global ranking in postal services can be dynamic and dependent on the specific parameters considered. Instead of focusing on a single position, it's helpful to acknowledge its strengths, like its widespread network and affordability, while also recognizing areas for improvement in terms of efficiency and modernization.

63. Meaning of Man - Land ratio is

(A) the ratio between the total population and the actual utilization of land in a country.

(B) the ratio between total land and total population of a country.

(D) the ratio between total agricultural land and total male population.

The meaning of "Man-Land Ratio" refers to the relationship between the total population of a region and the total available land in that region. Therefore, the most accurate option is:

(B) the ratio between total land and total population of a country.

Here's why the other options are inaccurate:

(A): While land utilization is relevant to population density, the Man-Land Ratio focuses on the overall availability of land, not just utilized land.
(C): The term doesn't differentiate between plain land and other types of land. It considers all available land within the region.
(D): The Man-Land Ratio considers the entire population, not just the male population or specifically agricultural land.

Therefore, remember that the Man-Land Ratio is a simple, general indicator of the population density within a region, indicating how many people inhabit a given geographical area

64. Which of the following is not a fundamental duty under the Indian Constitution?

(A) To protect monument of national importance

(B) To develop scientifle temper

65. If f (x) = 5’ + 1/5’+ 2, then the value of f(-x) is

(A) f(x)

(B)-f(x)

(-) (0)

(D)-(1)

Here's the breakdown:

1. Defining the notation:

5' denotes the fifth power of 5, so 5' = 5^5 = 3125.

2. Calculating f(x):

f(x) = 5^5 + 1/5^5 + 2
f(x) = 3125 + 1/3125 + 2
f(x) ≈ 3127.00032

3. Calculating f(-x):

f(-x) substitutes -x wherever x appears in the expression f(x).
Since 5' is a constant term, it remains the same: f(-x) = 5^5 + 1/5^5 + 2.
Therefore, f(-x) also equals 3127.00032.

4. Comparing f(x) and f(-x):

Since f(x) and f(-x) have the same value (≈ 3127.00032), the answer is:

(A) f(x)

Therefore, if f(x) = 5' + 1/5' + 2, then the value of f(-x) is also equal to f(x).

66. DadabhaiNaoroji was elected to the British House of Commons as a member of the party.

(A) Conservative

68. If number of molecules present in 9g of water is n, then number of molecules present in 44 g of carbon dioxide is

(A) π

(В) 2л

(D) 3n

To solve this question, we need to consider the concept of Avogadro's number. Avogadro's number, denoted by N_A, is approximately 6.022 × 10^23, and it represents the number of atoms or molecules in one mole of a substance.

Here's how we can solve the problem:

Find the number of moles in 9 grams of water:

First, find the molar mass of water (the mass of one mole of water). H2O has a molar mass of 2(1) + 16 = 18 grams/mol.
Now, divide the given mass of water (9 grams) by the molar mass: 9 grams / 18 grams/mol = 0.5 moles of water.

Find the number of molecules in 0.5 moles of water:

Multiply the number of moles by Avogadro's number: 0.5 moles * 6.022 × 10^23 molecules/mol = 3.011 × 10^23 molecules.

Find the number of moles in 44 grams of carbon dioxide:

Similar to step 1, find the molar mass of CO2 (12 + 2*16 = 44 grams/mol).
Now, divide the given mass of CO2 (44 grams) by the molar mass: 44 grams / 44 grams/mol = 1 mole of CO2.

Find the number of molecules in 1 mole of carbon dioxide:

Multiply the number of moles by Avogadro's number: 1 mole * 6.022 × 10^23 molecules/mol = 6.022 × 10^23 molecules.

Compare the number of molecules in water and carbon dioxide:

We found that 9 grams of water contain 3.011 × 10^23 molecules and 44 grams of CO2 contain 6.022 × 10^23 molecules.

Therefore, the number of molecules in 44 grams of carbon dioxide is twice the number of molecules in 9 grams of water, i.e., 2n.

So, the answer is (D) 3n.

69. In which substage of interphase is DNA doubled?

(A) G_1

(B) S

(D) G

Answer

(B) S is the substage of interphase during which DNA is doubled.

Here's why:

Interphase: This is the stage between cell divisions where the cell grows and prepares for the next division. It consists of three substages: G1, S, and G2.
G1 (Gap 1): This is the first growth phase where the cell synthesizes RNA and proteins needed for other cellular processes. DNA replication doesn't occur here.
S (Synthesis): This is the DNA synthesis phase where the cell replicates its DNA to create two identical copies of each chromosome. This duplication prepares the cell for mitosis or meiosis.
G2 (Gap 2): This is the second growth phase where the cell continues to grow and prepares for cell division. It involves protein synthesis and cell organelle duplication, but DNA replication doesn't take place again.

Therefore, remembering that the S phase of interphase is specifically dedicated to DNA replication is crucial for understanding cellular processes and cell division.

70. Who among the following has been given the power by the Indian Constitution to 'impose reasonable restrictions' on the fundamental rights?

(A) President

(B) Parliament

(D) Both (B) and (C)

The answer to this question is (D) Both (B) and (C). Both the Parliament and the Supreme Court have the power to impose reasonable restrictions on fundamental rights in the Indian Constitution.

Here's why:

Parliament: Through legislative power, the Parliament can enact laws that can restrict fundamental rights in certain circumstances. These restrictions must be "reasonable" and justified for certain public purposes such as national security, public order, morality, etc. This power is granted by Article 19 of the Constitution.
Supreme Court: Through judicial review, the Supreme Court can examine the constitutionality of laws that impose restrictions on fundamental rights. If the Court finds that the restrictions are not "reasonable" or are not justified for a valid public purpose, it can strike down the law or parts of it. This power is derived from the doctrine of basic structure and judicial review established by the Court.

Therefore, both the Parliament and the Supreme Court play a crucial role in balancing the protection of fundamental rights with the needs of society as a whole. While Parliament can enact laws with restrictions, the Supreme Court acts as a safeguard to ensure that these restrictions remain within reasonable bounds and don't unduly infringe upon individual liberties.

It's important to remember that even with the power to impose restrictions, fundamental rights are considered essential to a democratic society and their protection is paramount. These restrictions should be exercised meticulously and only for compelling reasons.

71. Who observed: "The Congress is in reality a civil war without arms"?

(A) Lord Dufferin

(B) M. A. Jinnah

(D) Lord Curzon

(A) Lord Dufferin

Here's why:

Lord Dufferin: Frederick Temple Hamilton Temple, Marquess of Dufferin and Ava, served as the Viceroy of India from 1884 to 1893. He wrote about the Indian National Congress in this way, expressing his view that the organization, despite advocating for peaceful means, represented a significant challenge to British colonial rule.
Other options: While the other figures played significant roles in Indian history, their views and statements don't align with the specific quote attributed in this question:
M. A. Jinnah: He was a prominent leader in the Muslim League and later became the founder of Pakistan. While he opposed the Indian National Congress on multiple occasions, his statements often focused on the partition of India and the rights of Muslims.
Sir Syed Ahmad Khan: He was a reformer and educationalist who championed the modernization of Muslim society in India. His views on the Congress primarily emphasized the need for Muslims to participate in politics within the framework of British rule.
Lord Curzon: He served as the Viceroy of India from 1899 to 1905. His policies were often regarded as more conservative and aimed at solidifying British control, making his viewpoint less likely to resonate with the quoted statement.

Therefore, remembering that Lord Dufferin made the observation about the Congress as a "civil war without arms" adds context to his perception of the political landscape in India during his tenure as Viceroy.

72. Ocean Thermal Energy Conversion- process was used for energy production in India in

(A) Kolkata

(B) Haldia

(D) Paradwip

While India is exploring Ocean Thermal Energy Conversion (OTEC) technology for potential future energy production, it hasn't implemented it commercially yet. Therefore, none of the provided locations, (A) Kolkata, (B) Haldia, (C) Madras/Chennai, or (D) Paradwip, have an operational OTEC plant currently.

However, India is taking promising steps towards OTEC research and development. Here's some relevant information:

Lakshadweep OTEC pilot project: The National Institute of Ocean Technology (NIOT) is currently establishing a 65 kW OTEC desalination plant at Kavaratti island in Lakshadweep. This project, expected to be operational by 2024, aims to demonstrate the feasibility of OTEC technology for power generation and desalination in India.
Other initiatives: NIOT is also engaged in other research and development activities related to OTEC, including resource assessment, technology advancements, and developing cost-effective OTEC designs.

So, while OTEC hasn't been used for active energy production in India yet, the future holds promise with ongoing research and development efforts focused on harnessing this sustainable energy source.

Remember, staying updated on emerging technologies like OTEC can help you stay informed about India's progress in diversifying its energy mix and exploring green energy solutions.

73. The major percentage of Central Government subsidy in 2023-24 is on

(A) Food

(B) Interest

(D) Petroleum

(A) Food

Here's why:

Based on the Union Budget 2023-24, the estimated expenditure on food subsidy is the highest, reaching Rs. 1.97 lakh crore, approximately 35% of the total major subsidies allocated for the fiscal year.
The expenditure on interest payments, while significant, comes in second place, estimated at Rs. 6.71 lakh crore. However, it's important to note that interest payments aren't technically considered "subsidies" in the usual sense, as they represent the cost of servicing government debt.
The budget allocated for fertilizer subsidies is Rs. 1.75 lakh crore, followed by petroleum subsidies at Rs. 54,200 crore. While substantial, they remain lower than the food subsidy amount.

Therefore, remembering that food subsidy accounts for the largest portion of the central government subsidy budget in 2023-24 provides valuable insight into the government's spending priorities and social policies.

74. In India the state with highest yield of Pulse (Dal) per hectare

79. The first cotton textile mill, in India was set up in

(A) Kolkata Ghusuri

(B) Kolkata-Sinthimore

(D) Thane

While some sources might mention other locations, the most widely accepted answer to the question of the first cotton textile mill in India is:

(A) Kolkata Ghusuri

Here's why:

Historical evidence: The mill, established in 1818 by the British East India Company, was known as the Fort Gloster Mills and located in Ghusuri, near Kolkata. While it wasn't commercially successful and eventually shut down, its historical significance as the first such mill in India cannot be disputed.
Recognition: Several historical accounts and academic references acknowledge the Fort Gloster Mills in Ghusuri as the pioneering cotton textile mill in India.

It's important to note that other cotton mills like the Bombay Spinning and Weaving Company (established in 1854) played crucial roles in the development of the Indian textile industry. However, in terms of historical precedence and being the first established mill, Kolkata Ghusuri still holds the title.

Therefore, remembering the Fort Gloster Mills in Kolkata Ghusuri as the first cotton textile mill in India adds to your knowledge of Indian industrial history and its early steps towards textile production.

80. Which of the following is not regarded as public expenditure in India?

(A) Subsidy given to local city bus service

(B) Defense expenditure

(D) Investment spending by public companies

Answer

(D) Investment spending by public companies

Here's why:

Public expenditure: This typically refers to the spending of the government and its various agencies on goods and services to fulfill public needs and welfare. It includes expenses like subsidies, defense, healthcare, education, infrastructure, and more.
Investment spending by public companies: While public companies might be owned by the government or have a significant government stake, their investment decisions aren't directly classified as public expenditure. Their investments are primarily driven by commercial considerations and their own profitability goals.

The other options are all considered part of public expenditure in India:

(A) Subsidy given to local city bus service: This represents a direct financial support by the government to promote public transportation and make it more accessible.
(B) Defense expenditure: This is the government's spending on maintaining and strengthening the armed forces, ensuring national security.
(C) Interest payment on national debt: This is the cost of servicing the debt incurred by the government through borrowing, a legitimate expense of the public finances.

Therefore, it's crucial to distinguish between spending directly made by the government for public welfare and the actions of individual public companies, even if they're government-owned, to accurately understand the scope of public expenditure in India.

(B) Balban: While Balban was a powerful Sultan known for consolidating the Delhi Sultanate, he primarily focused on consolidating territories within his existing domain and didn't initiate major Deccan campaigns.
(C) Firuz-Tughluq: FiruzTughluq succeeded AlauddinKhalji and focused on internal administration and consolidation rather than expansionary campaigns.
(D) Md. Bin-Tughlak: Although Mohammad Bin Tughluq attempted Deccan conquests, he wasn't the first. AlauddinKhalji had already launched and achieved significant success in Deccan expeditions before Md. Bin-Tughlak's reign.

Therefore, remembering that AlauddinKhalji was the pioneer of Deccan conquests adds to your understanding of his expansionary strategies and the historical dynamics of the Delhi Sultanate during his reign.

83. Five boys A, B, C, D and E play a game of cards. Each boy has 10 cards. E borre vs 3 cards from A and give away 5 to C who in turn gives 4 to B. while B passes 2 to D. How many cards does D have?

(A) 9

(B) 10

(D) 12

Here's how to calculate the number of cards D has:

Initial Cards: Each boy starts with 10 cards, so D initially has 10 cards.
Card Transfers:

A loses 3 cards to E, reducing his cards to 10 - 3 = 7.
E then gives 5 cards to C, increasing C's cards to 10 + 5 = 15.
C gives 4 cards to B, decreasing his cards to 15 - 4 = 11.
B gives 2 cards to D, increasing D's cards to 10 + 2 = 12.

Therefore, D has 12 cards after the series of card transfers.

So the answer is: (D) 12

84. Who introduced 'Din-i-Ilahi'?

(C) Jahangir: Akbar's son and successor, but didn't actively promote Din-i-Ilahi.
(D) Shahjahan: Grandson of Akbar and further abandoned the practice of Din-i-Ilahi.

Therefore, remembering that Akbar introduced Din-i-Ilahi adds to your knowledge of his reign and various social and religious initiatives during the Mughal era.

85. What happens when the potassium lodide solution is added to a solution of lead nitrate?

(A) White precipitation of lead iodide is formed.

(B) Yellow precipitation of lead iodide is formed.

(D) Black precipitation of lead iodide is formed.

When potassium iodide solution (KI) is added to a solution of lead nitrate (Pb(NO3)2), a yellow precipitation of lead iodide (PbI2) is formed. This reaction occurs due to a double displacement reaction, where the ions exchange partners:

2KI(aq) + Pb(NO3)2(aq) → PbI2(s) + 2KNO3(aq)

Therefore, the correct answer is:

(B) Yellow precipitation of lead iodide is formed.

It's important to remember that lead iodide has a characteristic yellow color, not white, red, or black.

88. In India Aman rice is cultivated during

(A) sown in S. W. Monsoon season and harvested in winter.

(B) sown in S. W. Monsoon season and harvested at the end of the monsoon.

(D) sown in early summer and harvested at the end of the monsoon.

(A) sown in S. W. Monsoon season and harvested in winter.

Here's why the other options are incorrect:

(B) sown in S. W. Monsoon season and harvested at the end of the monsoon: While sown during the monsoon, Aman rice matures and is harvested later, typically in December or January, marking the winter season.
(C) sown in summer and harvested in the monsoon: This description doesn't align with the typical timing of Aman rice cultivation, which requires the monsoon rains for initial growth and development.
(D) sown in early summer and harvested at the end of the monsoon: Similar to option B, the harvesting period for Aman rice extends beyond the end of the monsoon, reaching into winter.

Therefore, remembering that Aman rice is sown with the onset of the southwest monsoon and harvested during winter adds clarity to your understanding of this prominent rice cultivation cycle in India.

89. The rainfall type that causes most deaths onLadakh plateau-

(A) Frontal rain

(B) Hailstorm

(D) Convectional rain

the rainfall type that causes the most deaths on the Ladakh plateau is:

Here's why:

Ladakh's geography: The Ladakh plateau is a high-altitude desert region with limited vegetation and a fragile ecosystem. It receives very little rainfall throughout the year, with an average annual precipitation of around 100mm.
Cloud bursts: When intense precipitation occurs over a short period, typically exceeding 100mm in an hour, it's classified as a cloud burst. Such sudden and concentrated rainfall can trigger flash floods, mudslides, and debris flows, posing a significant threat to life and property on the Ladakh plateau.
Severity of impact: Compared to other forms of precipitation like frontal rain, hailstorms, or even moderate convective rain, cloud bursts have the most devastating impact on the Ladakh region. The rapid water flow caused by cloud bursts can easily overwhelm the dry channels and valleys, leading to catastrophic events like the 2010 Leh flood that claimed hundreds of lives.
Other rain types: While frontal rain or hailstorms can occur in Ladakh, they typically don't pose the same level of immediate danger as cloud bursts. Convectional rain, caused by localized heating and rising air, also contributes to some precipitation in the region, but its intensity and potential for disaster are much lower compared to cloud bursts.

Therefore, remembering that cloud bursts pose the greatest threat to lives on the Ladakh plateau due to their intense nature and ability to trigger flash floods and mudslides provides valuable insight into the environmental challenges of this unique region.

90. If721890 denotes PARDON, 53164 denotes MERCY, DEMOCRACY will denote

(A) 835971274

(B) 853961264

(D) 835961264

Answer

P in PARDON is represented by 721890.
M in MERCY is represented by 53164.

Looking at the differences between the corresponding letters and numbers:

P - M = 19
A - E = 5
R - R = 0
D - C = 1
O - Y = 7

Following this pattern, we can decipher the code for DEMOCRACY:

D = 5 (M + 1)
E = 8 (R + 3)
M = 5 (C + 0)
O = 6 (R + 1)
C = 5 (Y + 0)
R = 4 (A + 0)
A = 9 (Y + 0)
C = 4 (A + 0)
Y = 5 (C + 0)

Combining the deciphered numbers, DEMOCRACY is represented by:

835961264

Therefore, the answer is: (D) 835961264

92. A man encashes a cheque of 6000/- from a Bank. The Bank pays him in 200 rupee notes and

100 rupee notes, totalling 48. The number of 200 rupee notes is

(A) 20

(B) 12

(D) 24

Answer:

Let x be the number of 200 rupee notes.
Therefore, the number of 100 rupee notes will be 48 - x.
Value of 200 rupee notes = 200x
Value of 100 rupee notes = 100(48 - x)
Total value received = 6000
Equation: 200x + 100(48 - x) = 6000
Simplify: 200x + 4800 - 100x = 6000
Combine like terms: 100x + 4800 = 6000
Subtract 4800 from both sides: 100x = 1200
Divide both sides by 100: x = 12

Therefore, the number of 200 rupee notes is (B) 12.

Alternative method:

Assume all notes are 200 rupees. This would give you 30 notes (6000/200).
Now, replace one 200 rupee note with a 100 rupee note. This reduces the total value by 100.
You need to do this 18 times (30-12) to reach the actual total of 6000.
Therefore, there are 12 200 rupee notes.

Both methods lead to the same answer, confirming that the man receives 12 200 rupee notes.

93. All revenues received by the Union government by way of direct and indirect taxes, money borrowed and receipts from loans given by the government now into

(A) the Public Accounts of India.

(B) the Consolidated Fund of India.

(D) None of the above

Ans

(B) the Consolidated Fund of India.

Here's why the other options are incorrect:

(A) the Public Accounts of India: While public accounts track government receipts and expenditures, the Consolidated Fund represents the main pool of resources from which the government finances its expenses.
(C) the Contingency Fund of India: This fund serves a specific purpose for meeting unforeseen emergencies and isn't the primary repository for all government revenues.
(D) None of the above: As established by Article 266(1) of the Indian Constitution, the Consolidated Fund of India is the designated recipient of all Union government revenues and forms the backbone of the government's financial transactions.

Therefore, remembering that the Consolidated Fund of India plays this crucial role in the Indian government's financial system adds to your knowledge of public finance and resource allocation within the country.

95, Bal GangadharTilak was given the epithet of 'Lokmanya' (Universally Respected) during

(A) Swadeshi movement

(B) Revolutionary movement

(D) His imprisonment in 1908

ANS

(D) His imprisonment in 1908

Here's why:

The 1908 imprisonment: Following the publication of two articles in his newspapers Kesari and Mahratta criticizing the British administration, Tilak was charged with sedition and sentenced to six years of rigorous imprisonment. This event triggered widespread outrage and protests across India, solidifying Tilak's image as a fearless leader and champion of nationalist ideals.
Public support: During his trial and imprisonment, Tilak received immense public support and sympathy. People viewed him as a victim of British injustice and someone who dared to speak truth to power. This widespread respect and admiration led to the spontaneous bestowal of the "Lokmanya" title.
Connection to other movements: While Tilak was actively involved in various movements like Swadeshi, Home Rule, and the revolutionary struggle, his imprisonment in 1908 served as a catalyst for earning the "Lokmanya" title due to the immediate and unified public response.

96. The density of water at 20°C is 998 kgm and that at 40°C is 992 kgm. The coefficient of the cubical expansion of water is

(A) 2 x 10

(B) 6 x 10 °

(D) 4 x 10 °C

The coefficient of cubical expansion of water can be calculated using the following formula:

Coefficient of cubical expansion = (Change in density) / (Density at initial temperature * Change in temperature)

Here, we have:

Change in density = 998 kg/m³ - 992 kg/m³ = 6 kg/m³
Density at initial temperature (20°C) = 998 kg/m³
Change in temperature = 40°C - 20°C = 20°C

Substituting these values into the formula:

Coefficient of cubical expansion = (6 kg/m³) / (998 kg/m³ * 20°C) = 3.00 x 10^-3 °C^{-1}

Therefore, the answer is:

It's important to note that the negative sign indicates that the volume of water expands as the temperature rises, which is an anomalous behavior and crucial for understanding various water-related phenomena.
