The correct answer is sabha.

Key Points

• The correct answer is option 2, "sabha," which was an assembly of Brahmin landowners mentioned in the inscriptions of the Pallavas.
• "Naukayan" refers to a leader of a group of boats or ships, "parishad" refers to a council or committee, and "bhraman" is not a term commonly used in this context.
• The concept of local assemblies was important in the political organization of ancient India, and the Pallavas were one of the dynasties that ruled over parts of southern India during the early medieval period (3rd to 9th centuries CE).
• The role and composition of these assemblies varied across different regions and time periods, but they were generally involved in decision-making and dispute resolution related to local governance, land use, and social issues.
• The mention of Brahmin landowners in this context suggests that the Pallava sabha may have had a specific role in managing land rights and property disputes among this privileged social group.

Additional Information

• The inscriptions of the Pallavas mention a number of local assemblies.
• These assemblies functioned through subcommittees, which looked after irrigation, agricultural operations, making roads, local temples, etc.
• The Nagaram was an organization of merchants.
• It is likely that these assemblies were controlled by rich and powerful landowners and merchants.
• There were three types of places during this time:

• Sabha - Land granted to Brahmins and was also called Agrahara villages.
• Nagaram - Where merchants and traders resided

The correct answer is an independent judiciary.

Key Points

• The rule of law is the principle that everyone in a society, including the government, is subject to the law. This means that the law should be applied equally to everyone, without discrimination or favoritism.
• An independent judiciary is essential to upholding the rule of law. It means that judges are free from political influence or pressure, and can make decisions based solely on the facts and the law.
• Without an independent judiciary, there is a risk that the government could abuse its power and violate the rights of citizens. For example, if the judiciary is not independent, the government could use the courts to punish political opponents or suppress dissent.
• Freedom of speech is also an important part of democracy, but it is not the only factor that determines whether a society is governed by the rule of law. Similarly, a written constitution and sovereignty of the Parliament are important, but without an independent judiciary, they may not be enough to ensure that the rule of law is upheld.

<br>

Additional Information

• Freedom of speech is a fundamental right that allows individuals to express their opinions and ideas without censorship or fear of reprisal. It is protected by many democracies, including India. However, it is not an absolute right, and there may be limits on speech in certain circumstances (for example, to prevent hate speech or incitement to violence).
• A written constitution is a document that sets out the basic principles and rules of a country's government. It typically includes provisions on the separation of powers, individual rights, and the structure of government. India has a written constitution, which is one of the longest in the world.
• Sovereignty of the Parliament refers to the principle that the elected representatives of the people have the ultimate authority to make laws and govern the country. In India, Parliament is made up of two houses - the Lok Sabha (lower house) and the Rajya Sabha (upper house). However, this authority is not absolute, and is subject to the limitations imposed by the constitution and the rule of law.

The correct answer is the Himalayas.

Key Points

• The Himalayas are the mountain range that prevents the cold Siberian winds from entering India.

• The Himalayas are the highest mountain range in the world, and they run across the northern border of India.
• They are also home to some of the highest peaks in the world, including Mount Everest.
• The Satpura Range is a mountain range in central India, and it does not prevent the cold Siberian winds from entering India. The Aravali Hills are a range of mountains in western India, and they also do not prevent the cold Siberian winds from entering India.
• The Western Ghats are a mountain range that runs along the western coast of India, and they do not prevent the cold Siberian winds from entering India. However, they do play an important role in the monsoon season by blocking the southwest monsoon winds from entering the interior of India.

<br>

Additional Information Impact of Himalayan Mountains on India:

• Following are some of the important benefits that India derives from the Himalayan Mountains:
• The Himalayas influence the monsoon pattern as they effectively intercept the summer monsoons coming from the Bay of Bengal and the Arabian Sea which leads to precipitation in the form of snow or rain.
• The latest meteorological studies have revealed that the Himalayas are responsible for splitting the jet stream into two branches and these in turn are significant for the monsoons.
• By virtue of their high altitude, length, and direction they prevent the cold waves from coming from central Asia. Without these, winters would have been very severe.
• The Himalayan Mountains are a source of almost all the major rivers of India.
• The large glaciers and abundant rainfall are responsible for the mighty rivers of India.
• The rivers originating from the Himalayas travel large distances and carry enormous quantities of alluvium while descending from the Himalayas.
• The formation of the Indo-Gangetic plain is closely related to the formation of the Himalayas.
• The rivers which were previously flowing into the Tethys Sea (Before the Indian Plate collided with the Eurasian Plate - continental drift, plate tectonics) deposited a huge amount of sediments in the Tethys Geosyncline.

Given values: 24 and 12

To find the third proportional to two numbers, we use the formula a ∶ b = b ∶ x

⇒ 24 ∶ 12 = 12 ∶ x

⇒ x = (12 × 12)/24 = 6

Therefore, the third proportional to 24 and 12 is 6.

Calculation:

The condition of divisibility by 80 is that the last two digits should be zero.

As p and q are single digits, they must be 0.

Hence, p × q = 0 × 0 = 0.

Calculation:

If the two numbers are 2x and 3x, then (2x + 8) ∶ (3x + 8) = 8 ∶ 11

⇒ 22x + 88 = 24x + 64

⇒ 2x = 24

⇒ x = 12

Therefore, the numbers are 24 and 36.

Given:

The total surface area of a solid right circular cylinder is 1100 cm2

Formula used:

The total surface area of a cylinder is 2πrh + 2πr2

Calculation:

⇒ 2πrh = Total surface area - 2πr²

⇒ 2 × 22/7 × 7h = 1100 - 2 × 22/7 × 7²

⇒ h = (1100 - 308) / 44 = 18 cm

Now, the curved surface area = 2πrh = 2 × 22/7 × 7 × 18 = 792 cm²

Therefore, the curved surface area of the cylinder is 792 cm².

Given:

The height and the radius of a cone are 21 cm and 7√7 cm

Formula used:

V = 1/3πr2h

Calculation:

The volume of a cone is given by V = 1/3πr²h

⇒ V = 1/3 × 22/7 × (7√7)² × 21 = 7,546 cm³

Therefore, the volume of the cone is 7,546 cm³.

Given:

Akash can do a piece of work in 74 days.

Vishal can do this work in 37 days

Calculation:

One day work of Akash = 1/74

One day work of Vishal = 1/37

One day work of Akash and Vishal together = 1/74 + 1/37 = 3/74

Let's assume Vishal joins after x days

⇒ x/74 + (40 - x) × 3/74 = 1

⇒ x + 120 - 3x = 74

⇒ 2x = 46 

⇒ x = 23 days

Therefore, Vishal should join after 23 days.

Shortcut Trick

When the distance for both parts of the journey is equal, the Average Speed is the harmonic mean of the individual speeds.

Shortcut formula: Average Speed = (2 × S₁ × S₂) ÷ (S₁ + S₂)

Given S₁ = 30 km/h and S₂ = 20 km/h.

Average Speed = (2 × 30 × 20) ÷ (30 + 20) = 1200 ÷ 50 = 24 km/h.

∴ The correct answer is 24 km/h.

Alternate Method

Given:

Speed from Home to School (v₁) = 30 km/h

Speed from School to Home (v₂) = 20 km/h

Distance between Home and School (d) = 8 km

Formula Used: Average Speed = Total Distance ÷ Total Time

⇒ Total Distance = 8 + 8 = 16 km

⇒ Time for Home to School (t₁) = 8 ÷ 30 = 4/15 hours

⇒ Time for School to Home (t₂) = 8 ÷ 20 = 2/5 hours

⇒ Total Time = 4/15 + 2/5 = 4/15 + 6/15 = 10/15 = 2/3 hours

⇒ Average Speed = 16 ÷ (2/3) = 16 × 3 ÷ 2 = 24 km/h

∴ The correct answer is 24 km/h.

Additional Information

General Average Speed Formula

For any journey, Average Speed is the ratio of Total Distance to Total Time taken: v_avg = D_total ÷ T_total.

Equal Time Intervals

If a person travels at speed v₁ for time t and speed v₂ for the same time t, the Average Speed is the arithmetic mean: (v₁ + v₂) ÷ 2.

Unit Conversion

To convert speed from km/h to m/s, multiply by 5/18. To convert m/s to km/h, multiply by 18/5.

Total cost price = 20 × 372 = Rs. 7440

Total selling price = 20 × 12 × 32 = Rs. 7680

Profit = Selling price - Cost price = 7680 - 7440 = Rs. 240

Profit percentage = (Profit/Cost price) × 100

⇒ Profit percentage = (240/7440) × 100 = 3.22%

Therefore, the percentage profit was 3.22%.

Shortcut Trick

Using the Work Equivalence (MDH) formula: (M₁ × D₁) ÷ W₁ = (M₂ × D₂) ÷ W₂

Substitute the given values for both phases: (200 × 50) ÷ (1/4) = (M₂ × 100) ÷ (3/4)

⇒ 40000 = M₂ × 400 ÷ 3 ⇒ M₂ = 300 workers.

⇒ Additional workers needed = 300 − 200 = 100.

∴ The correct answer is 100 workers.

Alternate Method

Given:

Initial workers = 200

Total target time = 150 days

Work completed in 50 days = 1/4

Formula Used:

Total Work = Efficiency × Time

⇒ 200 workers complete 1/4 of the work in 50 days, so they would take 50 × 4 = 200 days to complete the full work.

⇒ Work completed in 50 days = 50 × 1 = 50 units.

⇒ Remaining work = 200 − 50 = 150 units.

⇒ Remaining time available = 150 − 50 = 100 days.

⇒ Required combined efficiency = 150 ÷ 100 = 1.5 units/day.

⇒ Since 200 workers provide 1 unit/day, 1 worker provides 1 ÷ 200 = 0.005 units/day.

⇒ Total workers required = 1.5 ÷ 0.005 = 300 workers.

⇒ Additional workers to employ = 300 − 200 = 100 workers.

∴ The correct answer is 100 workers.

Additional Information

Chain Rule (MDH Concept)

For a given piece of work, the relationship between Men (M), Days (D), Hours (H), and Work (W) is given by the formula: (M₁ × D₁ × H₁) ÷ W₁ = (M₂ × D₂ × H₂) ÷ W₂.

Work and Efficiency

Total Work is always equal to the product of Efficiency and Time. If the amount of work remains constant, Efficiency is inversely proportional to Time.

Work Equality in Changing Groups

When workers leave or join halfway through a project, calculate the work already completed, subtract it from the total work, and equate the remaining work to the new group's strength and remaining time limits.

Let's denote the initial population by P.

After two years, the population = P * (1 + 10/100) * (1 - 10/100)

Therefore, P = 990000 / ((1 + 10/100) * (1 - 10/100)) = 1,000,000.

The percent decrease is calculated by the formula: (Initial Value - Final Value) / Initial Value * 100%

⇒ Percent decrease = (34 - 8) / 34 * 100% =           76.47%

Therefore, the percent decrease in temperature is 76.47%.

Average speed = Total distance / Total time

Total distance = 450 km + 360 km + 150 km = 960 km

Total time = 450/30 + 360/40 + 150/50 = 27 hours

⇒ Average speed = 960 / 27 = 320/9 km/h

Therefore, the average speed during the whole journey is 320/9 km/h.

Given:

The marked price of book is Rs. 5000

Formula used:

Discount = Marked price - Selling price

Calculation:

⇒ Discount = 5000 - 4000 = Rs. 1000

Therefore, the discount on the book is Rs. 1000.

Shortcut Trick

For 3 years, the difference (D) between CI and SI is: D = P × (R/100)² × (3 + R/100)

⇒ 61.60 = P × (8/100)² × (3 + 8/100)

⇒ 61.60 = P × (64 / 10,000) × (308 / 100)

⇒ P = (61.60 × 1,000,000) ÷ (64 × 308) = 61,600,000 ÷ 19,712

⇒ P = ₹3,125

∴ The correct answer is ₹3,125.

Alternate Method

Given:

Rate (R) = 8% per annum | Time (T) = 3 years | Difference (D) = ₹61.60

Formula Used:

Difference for 3 years = PR²(300 + R) ÷ 100³

Calculations:

⇒ Let Principal = P

⇒ R = 8% = 2/25 (as a fraction)

⇒ Let P = 25³ = 15,625 units

⇒ Simple Interest (SI) for 1 year = 15,625 × (2/25) = 1,250 units

⇒ SI for 3 years = 1,250 × 3 = 3,750 units

⇒ Compound Interest (CI) for 3 years = 15,625 × [(1 + 2/25)³ − 1]

⇒ CI = 15,625 × [(27/25)³ − 1] = 15,625 × [19,683/15,625 − 1]

⇒ CI = 19,683 − 15,625 = 4,058 units

⇒ Difference = 4,058 − 3,750 = 308 units

⇒ Given: 308 units = ₹61.60

⇒ 1 unit = 61.60 ÷ 308 = ₹0.2

⇒ Principal = 15,625 × 0.2 = ₹3,125

∴ The correct answer is ₹3,125.

Additional Information

Difference for 2 Years

The difference between CI and SI for 2 years is D = P(R/100)².

Compound Interest Formula

The amount under CI is A = P(1 + R/100)^T and CI = A − P.

Effective Rate Method

For 8% for 3 years, effective SI is 24% and effective CI is 25.9712%, making the difference 1.9712% of Principal.

Formula used:

Average = sum of observations/total number of observations

Calculation:

Square of numbers: 25, 64, 81, 144, 225, and 256

Average = (25 + 64 + 81 + 144 + 225 + 256) / 6 = 132.50

Therefore, the average of the square of the given numbers is 132.50.

Shortcut Trick

Ratio of the numbers 12 : 16 ⇒ 3 : 4

HCF = Common divisor ⇒ 12 ÷ 3 = 4

LCM = HCF × Product of remaining ratios ⇒ 4 × 3 × 4 = 48

Required Sum = HCF + LCM = 4 + 48 = 52

∴ The correct answer is 52.

Alternate Method

Given: Numbers are 12 and 16.

Formula: LCM is the product of the highest powers of all prime factors; HCF is the product of the lowest powers of common prime factors.

⇒ Prime factorization of 12 = 2 × 2 × 3 = 2² × 3¹

⇒ Prime factorization of 16 = 2 × 2 × 2 × 2 = 2⁴

⇒ HCF = 2² = 4

⇒ LCM = 2⁴ × 3¹ = 16 × 3 = 48

⇒ Sum = HCF + LCM = 4 + 48 = 52

∴ The correct answer is 52.

Additional Information

Product Property

For any two numbers a and b, the product of the numbers is equal to the product of their HCF and LCM: a × b = HCF(a, b) × LCM(a, b).

Co-prime Numbers

Two numbers are said to be co-prime if their HCF is 1. In this case, their LCM is simply the product of the two numbers.

Divisibility Rule

The HCF of any set of numbers is always a factor of their LCM. This means LCM ÷ HCF will always result in an integer.

Calculation:

Let's assume the price tag on the sling bag was x.

The total discount is (x × 10/100) + ((x - x × 10/100) × 5/100)

Mayuri paid = x - total discount = Rs. 2565

Solving the equation gives x = Rs. 3000

Therefore, the price tag on the sling bag was Rs. 3000.

If selling price is 110% of cost price (10% profit), then cost price = Selling price / 110 * 100

⇒ Cost price = 29700 / 110 * 100 = ₹27,000

Therefore, the cost price of the phone for Suresh was ₹27,000.

Calculation:

If the price of sugar decreases by 5%, the consumption has to increase by Price/(Price - Decrease) × 100

⇒ Increased consumption = 100/(100 - 5) × 100 = 5.26%

Therefore, the family will have to increase the consumption of sugar by 5.26%.

Shortcut Trick

Calculation:

The distance traveled in 2 seconds = 4 × 3.75 = 15 m

Distance traveled in one hour = 15 m/2 s × 3600 s = 27000 m = 27 km

Therefore, the distance traveled in two hours = 2 × 27 = 54 km
