Given:

Total number of days = 6

Formula Used:

Average = Sum of all observations ÷ Total number of observations

Calculation:

According to the question,

⇒ Total sum of new users = 180 + 150 + 135 + 190 + 65 + 115

⇒ Total sum = 835

⇒ Average number of new users = Total sum ÷ Total number of days

⇒ Average = 835 ÷ 6

⇒ Average = 139.1666...

⇒ Average ≈ 139.17

∴ The correct answer is 139.17.

Given:

Number of hotels in S1 = 4400

Formula Used:

Total Number of Hotels = (Number of hotels in a State ÷ Percentage of that State) × 100

Number of hotels in a State = Total Number of Hotels × (Percentage of that State ÷ 100)

Calculation:

According to the question,

⇒ Number of hotels in S1 = 4400

⇒ Percentage of hotels in S1 = 22%

⇒ 22% of Total Hotels = 4400

⇒ Total Hotels = (4400 ÷ 22) × 100

⇒ Total Hotels = 200 × 100 = 20,000

Now, we need to find the state where the number of hotels is 2400.

⇒ Let the required percentage be x%

⇒ x% of 20,000 = 2400

⇒ (x ÷ 100) × 20,000 = 2400

⇒ 200 × x = 2400

⇒ x = 2400 ÷ 200

⇒ x = 12%

From the table/chart, 12% corresponds to State S2.

∴ The correct answer is S2.

Given:

Total number of nurses in H5 and H1 = 3240

Formula Used:

Value of a sector = (Degree of sector ÷ 360°) × Total Value

Percentage less = [(Higher Value − Lower Value) ÷ Higher Value] × 100%

Calculation:

According to the question,

⇒ Total degree sum for H5 and H1 = 54° + 54° = 108°

⇒ Given that 108° corresponds to 3240 nurses

⇒ Value of 1° = 3240 ÷ 108 = 30

⇒ Number of nurses in H1 = 54° × 30 = 1620

⇒ Number of nurses in H4 = 72° × 30 = 2160

Now, calculate the percentage by which nurses in H1 are less than those in H4:

⇒ Difference = 2160 − 1620 = 540

⇒ Percentage less = (Difference ÷ Number of nurses in H4) × 100%

⇒ Percentage less = (540 ÷ 2160) × 100%

⇒ Percentage less = (1 ÷ 4) × 100%

⇒ Percentage less = 25%

Alternatively, using degrees directly:

⇒ Percentage less = [(72° − 54°) ÷ 72°] × 100%

⇒ Percentage less = (18 ÷ 72) × 100% = 25%

∴ The correct answer is 25% (Option 4).

Shortcut Trick

Angle Bisector Theorem: The bisector of an angle divides the opposite side in the ratio of the other two sides.

Ratio BD : DC = AB : AC = 28 : 42 = 2 : 3

Total parts = 2 + 3 = 5 units

Given 5 units = 50 cm ⇒ 1 unit = 10 cm

BD = 2 units = 2 × 10 = 20 cm

∴ The correct answer is 20 cm.

Alternate Method

Given:

In ΔABC, AB = 28 cm, AC = 42 cm, BC = 50 cm.

AD is the internal angle bisector of ∠A meeting BC at D.

According to the Internal Angle Bisector Theorem:

⇒ BD / DC = AB / AC

Let BD = x cm, then DC = (50 − x) cm

⇒ x / (50 − x) = 28 / 42

⇒ x / (50 − x) = 2 / 3

⇒ 3 × x = 2 × (50 − x)

⇒ 3x = 100 − 2x

⇒ 5x = 100

⇒ x = 20

∴ The correct answer is 20 cm.

Additional Information

Internal Angle Bisector Theorem

The internal bisector of an angle of a triangle divides the opposite side internally in the ratio of the corresponding sides: BD/DC = AB/AC.

Length of Angle Bisector

The length of the internal bisector AD is given by AD² = (AB × AC) − (BD × DC). For this triangle, AD = √(28 × 42 − 20 × 30) = √576 = 24 cm.

External Angle Bisector Theorem

If AD' is the external bisector of ∠A meeting BC produced at D', then BD'/CD' = AB/AC.

Shortcut Trick

Profit Ratio (Kamal : Harshit) = (4800 × 4 + 6000 × 8) : (6000 × 4 + 4800 × 8)

⇒ Ratio = 67200 : 62400 = 672 : 624 = 14 : 13

Harshit's share (13 units) = ₹2600 ⇒ 1 unit = ₹200

Kamal's share (14 units) = 14 × 200 = ₹2800

∴ The correct answer is ₹2800.

Alternate Method

Given:

Kamal initial investment = ₹4800 | Harshit initial investment = ₹6000

After 4 months, Kamal adds ₹1200 | Harshit withdraws ₹1200

Annual profit of Harshit = ₹2600

Formula:

Profit Ratio = (Investment₁ × Time₁) : (Investment₂ × Time₂)

Calculations:

⇒ Total Investment value for Kamal = (4800 × 4) + (4800 + 1200) × 8

⇒ Kamal = 19200 + 48000 = ₹67200

⇒ Total Investment value for Harshit = (6000 × 4) + (6000 − 1200) × 8

⇒ Harshit = 24000 + 38400 = ₹62400

⇒ Ratio (Kamal : Harshit) = 67200 : 62400

⇒ Ratio = 672 : 624 = 28 : 26 = 14 : 13

⇒ Harshit's profit share = (13 / 27) × Total Profit = ₹2600

⇒ 13 units = ₹2600

⇒ 1 unit = 2600 ÷ 13 = ₹200

⇒ Kamal's profit share = 14 units = 14 × 200 = ₹2800

∴ The correct answer is ₹2800.

Additional Information

Partnership Profit Rule

In any business partnership, the profit is distributed among partners in the ratio of the product of their investments and the time duration: P₁ : P₂ = C₁ × T₁ : C₂ × T₂.

Compound Partnership

When partners invest different amounts for different periods of time, it is called a compound partnership. The effective capital is calculated by summing the products of various capitals and their respective time periods.

Ratio Simplification

To simplify the profit ratio, find the Highest Common Factor (HCF) of the calculated investment-time products and divide both sides by it.

Shortcut Trick

Let Cost Price (CP) = 100. Then Marked Price (MP) = 100 + 35% = 135.

Price after first 20% discount = 135 × 0.8 = 108.

Overall Profit = 8%, so Required Selling Price = 100 + 8% = 108.

Since the price after the first discount (108) is already equal to the target selling price (108), the second discount y must be 0%.

∴ The correct answer is 0%.

Alternate Method

Given:

Markup Percentage = 35%

First Discount (d₁) = 20%

Overall Profit Percentage = 8%

Calculations:

⇒ Let Cost Price (CP) = ₹100

⇒ Marked Price (MP) = 100 + 35% of 100 = ₹135

⇒ Price after 1st discount = 135 − (20/100) × 135 = 135 − 27 = ₹108

⇒ Required Final Selling Price (SP) for 8% overall profit = 100 + 8% of 100 = ₹108

⇒ Let the second successive discount be y%.

⇒ SP after second discount = 108 × (1 − y/100) = 108

⇒ 1 − y/100 = 108 ÷ 108 = 1

⇒ y/100 = 0

⇒ y = 0

∴ The correct answer is 0%.

Additional Information

Successive Discounts Formula

For two successive discounts d₁% and d₂%, the effective discount D% = d₁ + d₂ − (d₁ × d₂) ÷ 100.

CP, MP and Profit Relation

The relationship between Cost Price and Marked Price is given by: MP ÷ CP = (100 + Profit%) ÷ (100 − Discount%).

Effective Profit Percentage

Profit% = Markup% − Discount% − (Markup% × Discount%) ÷ 100. This formula calculates profit directly from markup and discount rates.

Shortcut Trick

Initial Ratio (Juice : Water) = 5 : 2 → (Multiply by 3) → 15 : 6

New Ratio (Juice : Water) = 8 : 3 → (Multiply by 2) → 16 : 6

Increase in Juice = 16 − 15 = 1 unit

Given: 1 unit = 15 L

Initial Total = 15 + 6 = 21 units = 21 × 15 L = 315 L

∴ The correct answer is 315 L.

Alternate Method

Initial ratio of grape juice and water = 5 : 2

Let the initial volume of grape juice be 5x and water be 2x.

Initial total volume = 5x + 2x = 7x

After adding 15 litres of juice, the new amount of juice = 5x + 15

The amount of water remains the same = 2x

According to the question:

⇒ (5x + 15) / 2x = 8 / 3

⇒ 3 × (5x + 15) = 8 × 2x

⇒ 15x + 45 = 16x

⇒ 16x − 15x = 45

⇒ x = 45

Initial total volume of the mixture = 7x

⇒ 7 × 45 = 315 L

∴ The correct answer is 315 L.

Shortcut Trick

Total ratio units = 2 + 3 + 5 = 10 units.

10 units = ₹1,500 ⇒ 1 unit = ₹150.

A share = 2 × 150 = ₹300.

B share = 3 × 150 = ₹450.

C share = 5 × 150 = ₹750.

∴ The correct answer is A = ₹300, B = ₹450, C = ₹750.

Alternate Method

Given:

Total Sum = ₹1,500

Ratio of A : B : C = 2 : 3 : 5

Formula Used:

Individual Share = (Individual Ratio / Total Ratio Parts) × Total Sum

⇒ Total Ratio Parts = 2 + 3 + 5 = 10

⇒ Share of A = (2/10) × 1,500 = 2 × 150 = ₹300

⇒ Share of B = (3/10) × 1,500 = 3 × 150 = ₹450

⇒ Share of C = (5/10) × 1,500 = 5 × 150 = ₹750

∴ The correct answer is A = ₹300, B = ₹450, C = ₹750.

Divisibility rule for 3: Sum of digits must be a multiple of 3.

Sum of digits for 39P6 = 3 + 9 + P + 6 = 18 + P.

Since 18 is already divisible by 3, P must be 0, 3, 6, or 9.

Among the options, 7 is the only value that makes the sum (18 + 7 = 25) not divisible by 3.

∴ The correct answer is 7.

Alternate Method

Given: The number 39P6 is divisible by 3.

Property: A number is divisible by 3 if the sum of its digits is divisible by 3.

⇒ Sum of digits = 3 + 9 + P + 6 ⇒ Sum = 18 + P ⇒ Since 39P6 is divisible by 3, (18 + P) mod 3 = 0 ⇒ For P = 0: 18 + 0 = 18 (18 ÷ 3 = 6, Remainder = 0) ⇒ For P = 3: 18 + 3 = 21 (21 ÷ 3 = 7, Remainder = 0) ⇒ For P = 6: 18 + 6 = 24 (24 ÷ 3 = 8, Remainder = 0) ⇒ For P = 7: 18 + 7 = 25 (25 ÷ 3 = 8, Remainder = 1) ⇒ Since the remainder is not 0 for P = 7, the number is not divisible by 3.

∴ The correct answer is 7.

Additional Information

Divisibility by 9

Similar to the rule for 3, a number is divisible by 9 if the sum of its digits is a multiple of 9.

Divisibility by 4

Alternate Method

Given: Length (l) = 5 cm, Diagonal (d) = 13 cm

Formula: Diagonal² = Length² + Width² (Pythagoras Theorem)

⇒ 13² = 5² + w²

⇒ 169 = 25 + w²

⇒ w² = 169 − 25 = 144

⇒ w = √144 = 12 cm

⇒ Area = Length × Width

⇒ Area = 5 × 12 = 60 cm²

∴ The correct answer is 60 cm².

Perimeter units = 2 × (3 + 1) = 8 units.

8 units = 64 cm ⇒ 1 unit = 8 cm.

Sides are 24 cm (Length) and 8 cm (Breadth).

Diagonal = 8 × √(3² + 1²) = 8√10 cm.

∴ The correct answer is 8√10 cm.

Alternate Method

Given:

Perimeter of rectangle = 64 cm

Length (L) = 3 × Breadth (B)

Formula Used:

Perimeter = 2 × (L + B)

Diagonal = √(L² + B²)

Calculations:

⇒ Let the Breadth be x cm. Then Length = 3x cm.

⇒ 2 × (3x + x) = 64

⇒ 2 × 4x = 64

⇒ 8x = 64 ⇒ x = 8

⇒ Breadth = 8 cm and Length = 3 × 8 = 24 cm.

⇒ Diagonal = √(24² + 8²)

⇒ Diagonal = √(576 + 64)

⇒ Diagonal = √640

⇒ Diagonal = √(64 × 10) = 8√10 cm.

Shortcut Trick

The average of n consecutive numbers is the middle term of the series.

For 8 consecutive numbers, the average (57) lies exactly between the 4th and 5th terms.

4th term = 57 − 1 = 56 (since even numbers have a gap of 2).

3rd term = 4th term − 2 = 56 − 2 = 54.

∴ The correct answer is 54.

Alternate Method

Given: Average of 8 consecutive even natural numbers = 57.

Let the 8 consecutive even numbers in ascending order be x, x+2, x+4, x+6, x+8, x+10, x+12, x+14.

⇒ Sum of 8 numbers = 57 × 8 = 456

⇒ x + (x+2) + (x+4) + (x+6) + (x+8) + (x+10) + (x+12) + (x+14) = 456

⇒ 8x + 56 = 456

⇒ 8x = 400

⇒ x = 50

⇒ 3rd number = x + 4 = 50 + 4 = 54

∴ The correct answer is 54.

Shortcut Trick

In any sequence of consecutive natural numbers (Arithmetic Progression), the average is always the middle value.

The average is also equal to the mean of the first and last terms.

Formula: Average = (Smallest number + Largest number) ÷ 2

Given: Average = A

Sum of smallest and largest = 2 × Average = 2 × A = 2A

∴ The correct answer is 2A.

Alternate Method

Given: Total consecutive terms (n) = 19, Average = A

Formula: Average = (First term + Last term) ÷ 2

⇒ Let the 19 consecutive natural numbers be x, (x + 1), (x + 2), ..., (x + 18).

⇒ Average = [Sum of all terms] ÷ 19

⇒ In an AP, Average = (Smallest + Largest) ÷ 2

⇒ A = [x + (x + 18)] ÷ 2

⇒ A = (2x + 18) ÷ 2

⇒ 2A = 2x + 18

⇒ Sum of smallest and largest = x + (x + 18) = 2x + 18

⇒ From the previous step, 2x + 18 = 2A

∴ The correct answer is 2A.

Additional Information

Average of AP

For any sequence in Arithmetic Progression, the Average = (First Term + Last Term) ÷ 2 = Middle Term (if n is odd).

Sum of n Consecutive Numbers

The sum of n consecutive natural numbers starting from x is S = (n ÷ 2) × [2x + (n − 1)].

If the number of terms n is odd, the middle term is the [(n + 1) ÷ 2]^th term, which represents the average.

Shortcut Trick

In parallel lines, corresponding angles are equal.

∠RSD = ∠PRB = 74°

Angles on a straight line (linear pair) sum to 180°.

∠DSQ = 180° − ∠RSD = 180° − 74° = 106°

∴ The correct answer is 106°.

Alternate Method

Given: AB || CD, ∠PRB = 74°.

Formula Used: Corresponding angle property and Linear pair property.

⇒ Since AB || CD and PQ is the transversal, ∠PRB and ∠RSD are corresponding angles.

⇒ ∠RSD = ∠PRB = 74°

⇒ Now, S lies on the transversal line PQ, making ∠RSD and ∠DSQ a linear pair.

⇒ ∠RSD + ∠DSQ = 180°

⇒ 74° + ∠DSQ = 180°

⇒ ∠DSQ = 180° − 74°

⇒ ∠DSQ = 106°

∴ The correct answer is 106°.

Additional Information

Corresponding Angles

Angles in the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, corresponding angles are equal.

Linear Pair

A pair of adjacent angles formed by intersecting lines. The sum of the angles in a linear pair is always 180°.

Alternate Interior Angles

Angles between the parallel lines on opposite sides of the transversal. They are always equal (∠ARS = ∠RSD).

Co-Interior Angles

Angles on the same side of the transversal between the two parallel lines. Their sum is always 180° (∠BRS + ∠RSD = 180°).

Shortcut Trick

Draw a line parallel to AB passing through point C.

Angle between BC and the parallel line = 180° − 120° = 60° (Consecutive Interior Angles).

Angle between CD and the parallel line = 180° − 120° = 60° (Consecutive Interior Angles).

The total angle at point C on a straight line is 180°.

∠BCD = 180° − (60° + 60°) = 60°.

∴ The correct answer is 60°.

Alternate Method

Given:

∠ABC = 120°

∠EDC = 120°

AB ∥ DE

Step-by-step Calculation:

⇒ Let us draw a line PCQ passing through C such that PQ ∥ AB ∥ DE.

⇒ Since AB ∥ PQ, then ∠ABC + ∠BCP = 180° (Sum of consecutive interior angles).

⇒ 120° + ∠BCP = 180°

⇒ ∠BCP = 180° − 120° = 60°

⇒ Since DE ∥ PQ, then ∠EDC + ∠DCQ = 180° (Sum of consecutive interior angles).

⇒ 120° + ∠DCQ = 180°

⇒ ∠DCQ = 180° − 120° = 60°

⇒ Now, PCQ is a straight line, so ∠BCP + ∠BCD + ∠DCQ = 180°.

⇒ 60° + ∠BCD + 60° = 180°

⇒ ∠BCD + 120° = 180°

⇒ ∠BCD = 180° − 120° = 60°

∴ The correct answer is 60°.

Additional Information

Consecutive Interior Angles

When two parallel lines are intersected by a transversal, the pairs of angles on the same side of the transversal inside the parallel lines are supplementary (Sum = 180°).

The correct answer is Cinnabar.

Key Points

• Cinnabar is the primary and most common ore of mercury (Hg).
• Chemically, it is known as Mercury(II) sulfide and its chemical formula is HgS.
• It typically appears as a bright red or brownish-red crystalline solid, which has been historically used as a pigment known as vermilion.
• The extraction of mercury from cinnabar involves roasting the ore in a furnace. During this process, sulfur in the ore combines with oxygen to form sulfur dioxide, and the mercury vaporizes.
• The mercury vapor is then cooled and condensed to collect liquid mercury.

Additional Information

• Bauxite:
• It is the principal ore of Aluminium (Al).
• It is not a specific mineral but a sedimentary rock with high aluminum content, primarily consisting of gibbsite, boehmite, and diaspore.
• Australia is the world's largest producer of bauxite, while in India, the state of Odisha is the leading producer.
• Magnetite:
• It is one of the most important ores of Iron (Fe).
• Its chemical formula is Fe3O4 and it is known for its natural magnetic properties, often called lodestone.
• It has a very high iron content, approximately 72.4%, making it a high-quality ore.
• Malachite:
• It is a copper carbonate hydroxide mineral with the formula Cu2CO3(OH)2.
• It is a minor ore of Copper (Cu) and is easily recognizable by its distinct bright green color.
• It was often used as a mineral pigment in green paints in ancient times.

Important Points

• Mercury (Hg): It is also known as quicksilver and is the only common metal that is liquid at standard temperature and pressure.
• Applications: Due to its uniform thermal expansion, mercury is used in thermometers, barometers, and manometers. It is also used in fluorescent lighting and dental amalgams.
• Amalgams: Mercury can dissolve many other metals (like gold and silver) to form alloys called amalgams. However, it does not form amalgams with iron, which is why it is often stored in iron flasks.
• Toxicity: Mercury is highly toxic to humans. Minamata disease is a neurological syndrome caused by severe mercury poisoning, famously occurring in Japan in the 1950s.

p- The correct answer is United Kingdom.

The correct answer is Aravali.

Key Points

• Himadri, also known as the Great Himalayas or Inner Himalayas, is the northernmost and most continuous range of the Himalayan mountain system. It contains the highest peaks in the world, such as Mount Everest and Kanchenjunga, with an average elevation of 6,000 meters.
• Himachal, or the Lesser Himalayas, lies to the south of the Himadri. This range is mainly composed of highly compressed and altered rocks, with an altitude varying between 3,700 and 4,500 meters. It is famous for its hill stations like Shimla, Mussoorie, and Nainital.
• Shiwalik is the outermost range of the Himalayas. It extends over a width of 10-50 km and has an altitude varying between 900 and 1,100 meters. These ranges are composed of unconsolidated sediments brought down by rivers from the main Himalayan ranges located farther north.
• Aravali is one of the oldest fold mountain ranges in the world and is located in the western part of India, primarily in Rajasthan. It is not part of the Himalayan mountain system, which is a much younger geological formation. Hence, Aravali is NOT a division of the Himalaya.

Additional Information

• Himalayan Mountain System:
• The Himalayas are geologically young and structurally fold mountains that stretch across the northern borders of India.
• They run in a west-east direction from the Indus River to the Brahmaputra River, covering a distance of about 2,400 km.
• The width of the Himalayas varies from 400 km in Kashmir to 150 km in Arunachal Pradesh.
• Aravali Range:
• The Aravali Range dates back to the Proterozoic Era, making it significantly older than the Himalayas, which were formed during the Tertiary Period.
• It spans approximately 692 km, starting from Gujarat, passing through Rajasthan and Haryana, and ending in Delhi.
• The highest peak of the Aravali Range is Guru Shikhar, located on Mount Abu, with an elevation of 1,722 meters.
• The range serves as a barrier preventing the eastward expansion of the Thar Desert.

Important Points

• Longitudinal Valleys (Duns): The longitudinal valleys lying between the Lesser Himalayas (Himachal) and the Shiwaliks are known as Duns. Well-known examples include Dehra Dun, Kotli Dun, and Patli Dun.
• Trans-Himalayas: Located immediately north of the Great Himalayan range, this region includes the Karakoram, Ladakh, and Zanskar ranges. It is also known as the Tethys Himalayas.
• Regional Divisions: Apart from longitudinal divisions, the Himalayas are also divided from west to east:
• Punjab Himalayas (between Indus and Sutlej).
• Kumaon Himalayas (between Sutlej and Kali).
• Nepal Himalayas (between Kali and Teesta).
• Assam Himalayas (between Teesta and Dihang).

The correct answer is Iron.

Key Points

• The Harappan Civilization, also known as the Indus Valley Civilization (IVC), belonged to the Bronze Age (circa 3300 BCE to 1300 BCE).
• While the Harappans were highly advanced in metallurgy, Iron was unknown to them. The use of iron in the Indian subcontinent began much later, during the Vedic Period around 1000 BCE. Hence, option 1 is the correct answer.
• Archaeological excavations at major sites like Harappa, Mohenjo-daro, and Lothal have revealed a wide variety of artifacts made of Copper, Bronze, Gold, and Silver, but no iron implements have been discovered.
• The Harappans produced Bronze by mixing Copper with Tin. Copper was sourced from the Khetri mines in Rajasthan, while Tin was likely imported from Afghanistan.
• The absence of Iron suggests that the Harappans relied on softer metals and stone tools for agriculture, construction, and warfare.

Additional Information

• Use of Copper and Bronze:
• Copper was the first metal to be used extensively by the Harappan people. They manufactured tools like axes, saws, knives, and spearheads.
• The invention of Bronze allowed for the creation of more durable tools and artistic figures, marking a significant technological leap.
• Precious Metals (Gold and Silver):
• Gold was used to create elaborate jewelry, including necklaces, bangles, and earrings. It is believed to have been sourced from Southern India (modern-day Karnataka) and Afghanistan.
• Silver was also widely used for making vessels and ornaments. The Harappans were among the earliest people in the world to use silver.
• Lead and Tin:
• The Harappans were aware of Lead and Antimony. Tin was a rare commodity and its scarcity is reflected in the limited number of high-quality bronze artifacts compared to copper ones.
• Trade and Metallurgy:
• The civilization maintained active trade links with Mesopotamia (modern-day Iraq) and Oman, exchanging metal goods for other commodities.

Important Points

• Technological Limitations: Smelting Iron requires a much higher temperature (approx 1538°C) compared to Copper (approx 1085°C). The Harappans had not yet developed the advanced furnace technology required to extract iron from its ore.
• Lost-Wax Technique: One of the most famous metal artifacts of this era is the "Dancing Girl" statue found at Mohenjo-daro, created using the Cire Perdue or lost-wax casting method.
• Transition to Iron Age: The Iron Age in India is associated with the Painted Grey Ware (PGW) culture. Early evidence of iron usage has been found at sites like Atranjikhera in Uttar Pradesh, dating back to approximately 1000 BCE, which is long after the decline of the mature Harappan phase.
• Agricultural Implements: Due to the lack of Iron, Harappan farmers used wooden plows and copper/bronze sickles for harvesting crops like wheat and barley.

The correct answer is By transpiration.

Key Points

• Transpiration is the biological process through which plants eliminate excess water in the form of water vapor from their aerial parts, primarily the leaves.
• Approximately 97-99% of the water absorbed by a plant's roots is not utilized for growth or photosynthesis but is instead released into the atmosphere via this process.
• This process mainly occurs through microscopic pores called stomata, which are located on the underside of the leaves and are regulated by guard cells.
• Transpiration serves several vital functions, including the creation of a transpirational pull (suction force) that aids in the upward transport of water and minerals from the soil to the top of the plant.
• It also helps in thermoregulation, providing a cooling effect to the plant during hot weather, similar to sweating in humans.
• Hence, the correct option is By transpiration.

Additional Information

• Types of Transpiration:
• Stomatal Transpiration: This is the most common type, accounting for about 80-90% of the total water loss through stomata.
• Cuticular Transpiration: Occurs through the cuticle (waxy layer) of the leaf, contributing to about 5-10% of water loss.
• Lenticular Transpiration: Water loss that happens through lenticels, which are small openings in the bark of woody stems.
• Factors Affecting Rate:
• Light: Increases the rate as stomata open in the presence of sunlight.
• Temperature: A higher temperature increases the rate of evaporation, thereby increasing transpiration.
• Humidity: If atmospheric humidity is high, the rate of transpiration decreases because the air is already saturated with moisture.
• Wind Speed: Moving air removes water vapor from the leaf surface, increasing the rate.
• Guttation: This is another method of water loss where water is released in liquid droplets from the edges of leaves through specialized structures called hydathodes. It usually occurs at night or early morning when soil moisture is high and transpiration is low.

Important Points

• Xylem: This is the specialized vascular tissue responsible for the conduction of water and nutrients from the roots to the rest of the plant.
• Cohesion-Tension Theory: This scientific theory explains how water moves upwards against gravity. It relies on the cohesive forces between water molecules and the tension created by transpiration in the leaves.
• Potometer: A laboratory instrument used by botanists to measure the rate of transpiration in a plant shoot.
• Adaptations: Xerophytes (plants in dry climates, like cacti) have adapted features such as sunken stomata, thick cuticles, or leaves modified into spines to minimize water loss.
• Environmental Impact: Transpiration is a key component of the water cycle, as it contributes significantly to atmospheric moisture and rainfall patterns.

The correct answer is Neither I Nor II.

Key Points

• Article 26 of the Indian Constitution provides the freedom to manage religious affairs. It states that every religious denomination has the right to establish and maintain institutions for religious and charitable purposes, manage its own affairs in matters of religion, and own and acquire movable and immovable property. Hence, statement I is incorrect.
• Article 27 of the Constitution relates to the freedom as to payment of taxes for promotion of any particular religion. It mandates that no person shall be compelled to pay any taxes, the proceeds of which are specifically used for the promotion or maintenance of any particular religion or religious denomination. Hence, statement II is incorrect.
• Both articles are part of the Right to Freedom of Religion, which is a Fundamental Right guaranteed under Part III of the Constitution of India.
• The statements provided in the question have swapped the definitions of the two articles, making both descriptions factually wrong in the context of the Article numbers mentioned.
• Hence, the correct answer is Neither I Nor II.

Additional Information

• Right to Freedom of Religion (Articles 25–28):
• Article 25: Guarantees freedom of conscience and the right to freely profess, practice, and propagate religion to all citizens. This right is subject to public order, morality, and health.
• Article 26: Protects collective religious rights. It allows religious denominations to manage their own internal affairs without state interference, provided they do not violate public order.
• Article 27: Prevents the State from using taxpayer money to favor one religion over another, upholding the secular character of the Indian polity.
• Article 28: Prohibits religious instruction in educational institutions wholly maintained out of State funds. In other institutions recognized by the State or receiving aid, religious instruction is permitted only with the consent of the individual (or guardian).

Important Points

• Difference between Tax and Fee:
• Under Article 27, the State is prohibited from levying a tax for religious promotion. However, the courts have clarified that the State can levy a fee to provide secular services, such as providing safety, health, and sanitation facilities for pilgrims during festivals or at religious sites.
• Religious Denominations:
• For a group to be considered a religious denomination under Article 26, it must be a collection of individuals who have a system of beliefs (doctrines) which they regard as conducive to their spiritual well-being, a common organization, and a distinctive name.
• Secularism in India:
• The inclusion of these articles reinforces the Positive Concept of Secularism in India, where the State maintains an equal distance from all religions and gives equal respect to all faiths, rather than a total separation of state and religion seen in Western models.

• This landmark amendment moved five subjects from the State List to the Concurrent List to ensure national uniformity.
• The transferred subjects are Education, Forests, Weights and Measures, Protection of Wild Animals and Birds, and Administration of Justice (excluding the Supreme Court and High Courts).
• Legislative Supremacy and Article 254:
• If there is a conflict between a law made by the Parliament and a law made by a State Legislature on a subject in the Concurrent List, the Central law prevails.
• However, if the State law has been reserved for the consideration of the President and has received his assent, the State law prevails in that particular state.
• Residuary Powers:
• Subjects that are not mentioned in any of the three lists are called Residuary Subjects.
• According to Article 248, the power to legislate on these subjects is vested solely in the Union Parliament.
• Examples of Concurrent List Subjects:
• Key subjects include Criminal Law, Marriage and Divorce, Bankruptcy and Insolvency, Trusts and Trustees, Civil Procedure, Contempt of Court, and Vital Statistics (including registration of births and deaths).
• The final entry, number 47, specifically relates to fees in respect of any of the matters in the list, excluding fees taken in any court.

• Lai Tribe: The Lai people have a distinct dialect and cultural practices within the broader Mizo identity, and Chawng Laizawn is a key marker of their specific ethnic pride.
• Instruments: Traditional Mizo music heavily relies on percussion. The Khuang (drum) is considered the most important instrument and is used in almost all folk dances.
• Mizoram Statehood: Mizoram became the 23rd state of the Indian Union on 20 February 1987, following the Mizo Accord of 1986.

The correct answer is Uttar Pradesh.

Key Points

• Kajri is one of the most prominent folk song and dance genres of India, predominantly famous in the state of Uttar Pradesh and some parts of Bihar.
• It is traditionally associated with the monsoon season, specifically the months of Shravan and Bhadrapada (typically July, August, and September), when the dark clouds bring relief from the summer heat.
• The origin of Kajri is believed to be the city of Mirzapur in Eastern Uttar Pradesh. Legend suggests it evolved from the longing of a woman for her husband during the rainy season.
• The performance of Kajri is a vital part of the Teej festival, where women gather, sing, and dance while enjoying swings in the rain.
• It is usually sung in the Bhojpuri and Maithili dialects, reflecting the local culture and rural lifestyle of the Gangetic plains. Hence, the correct answer is Uttar Pradesh.

The correct answer is June.

Key Points

• Ganga Dussehra, also known as Gangavataran, is a major Hindu festival celebrated to commemorate the descent of the holy River Ganga from heaven to earth.
• The festival is observed on the Dashami (10th day) of the Shukla Paksha (waxing phase of the moon) during the Hindu month of Jyeshtha.
• In the Gregorian calendar, this auspicious day typically falls in the month of June, though occasionally it may begin in late May depending on the lunar cycle.
• The festival marks the successful culmination of the intense penance performed by King Bhagiratha, who sought to bring the river to earth to liberate the souls of his ancestors. Hence, the statement regarding the month is correct.
• It is believed that on this specific day, the goddess Ganga descended from the heavens, making it one of the most sacred days for purification and spiritual merit.

Additional Information

• Significance of the Name: The word Dussehra is derived from the Sanskrit words 'Dasha' (ten) and 'Hara' (to destroy/remove). It signifies the removal of ten types of sins (three physical, four verbal, and three mental) through the grace of the river.

The correct answer is less, decrease.

Key Points

• Population change refers to the change in the number of people during a specific time period. This is a dynamic process influenced by three main factors: births, deaths, and migration.
• The Birth rate is the number of live births per 1,000 people in a year, while the Death rate is the number of deaths per 1,000 people in a year.
• When the birth rate is less than the death rate, it signifies that the number of people dying exceeds the number of babies being born. As a result, the total population will decrease over that period, assuming no significant inward migration. Hence, the statement aligns with the logic of natural decrease.
• The difference between the birth rate and the death rate of a country is called the natural growth rate. If the death rate is higher, the natural growth rate becomes negative.
• Until the 1800s, the world's population grew steadily but slowly because, although many babies were born (high birth rate), the death rate was also high due to poor health facilities and food shortages.
• In modern times, many developed nations have seen a population decline because their birth rate has fallen below the death rate, a phenomenon often observed in countries with aging populations.

Additional Information

• Components of Population Change:
• There are three primary components: Births, Deaths, and Migration. While births and deaths are natural causes, migration is a man-made or induced cause of change.
• Natural Increase occurs when the birth rate is higher than the death rate. This was the primary reason for the population explosion in the 20th century.
• Migration Dynamics:
• Migration is the movement of people across boundaries. It can be internal (within the country) or international (between countries).
• Immigration is when a person arrives in a new country, increasing its population, while Emigration is when a person leaves a country, decreasing its population.
• Countries like the United States of America and Australia have gained in-numbers by in-migration or immigration.
• Demographic Transition:
• This is a model used to represent the transition from high birth and death rates to low birth and death rates as a country develops from a pre-industrial to an industrialized economic system.
• In the final stage of demographic transition, both birth and death rates decline significantly, often leading to a stable or declining population.
• Factors Influencing Rates:
• Birth rates are influenced by social factors, education levels (especially of women), and economic stability.
• Death rates have plummeted globally due to advancements in medicine, better sanitation, and improved nutrition.
• The World Population reached 8 billion in November 2022, largely driven by high natural increase in developing regions.

Important Points

• Statistical Facts:
• A stationary population occurs when the birth rate is exactly equal to the death rate and there is no net migration.
• The Infant Mortality Rate (IMR) and Maternal Mortality Rate (MMR) are critical subsets of the death rate that reflect the socio-economic development and healthcare quality of a nation.
• The Replacement Level Fertility is the total fertility rate—the average number of children born per woman—at which a population exactly replaces itself from one generation to the next, without migration. This value is roughly 2.1 in most countries.

The correct answer is Manufacturing.

Key Points

• The Primary Sector of the economy includes all those activities the end purpose of which consists of exploiting natural resources. It forms the base for all other products that we subsequently make.
• Fishing is a primary activity because it involves the direct extraction of aquatic resources from nature without significant chemical or mechanical transformation at the point of harvest. Hence, it is included in the primary sector.
• Mining involves the extraction of minerals and ores directly from the earth's crust. Since it deals with raw earth materials, it is classified under the primary sector. Hence, it is included in the primary sector.
• Forestry involves activities such as logging, timber production, and the collection of wild-grown forest products. It relies entirely on the biological and environmental growth of forests. Hence, it is included in the primary sector.
• Manufacturing refers to the process of converting raw materials into finished goods using machinery, tools, and labor. This activity adds value to primary products and is categorized under the Secondary Sector. Hence, statement 3 is not included in the primary sector and is the correct answer.

Additional Information

• Sectors of Economy:
• Primary Sector: This sector is also known as the Agriculture and Related Sector. It includes Agriculture, Dairy, Fishing, Forestry, and Mining. In developing countries like India, it remains a significant provider of employment.
• Secondary Sector: This sector covers activities in which natural products are changed into other forms through ways of manufacturing. It is also called the Industrial Sector. Examples include Textile mills, Steel plants, and Automobile assembly.
• Tertiary Sector: Often called the Service Sector, it provides support to the primary and secondary sectors. It includes Transport, Banking, Insurance, Education, and Health Services. It currently contributes the highest share to India's GDP.
• Advanced Classifications:
• Quaternary Sector: This is a knowledge-based part of the economy, including services such as Information Technology (IT), Research and Development (R&D), and Financial planning.
• Quinary Sector: This includes the highest level of decision-making in a society or economy. This includes top officials in Government, Science, and Universities.
• Indian Context:
• In India, while the primary sector employs nearly 45-50% of the workforce, its contribution to the Gross Value Added (GVA) is relatively lower compared to the service sector, highlighting the issue of disguised unemployment in rural areas.

Important Points

• Workers in the primary sector are often called Red-collar workers due to the outdoor nature of their work.
• Workers in the secondary sector (specifically physical labor) are known as Blue-collar workers.
• The transition of an economy from primary to secondary and then to tertiary is known as Structural Transformation. In India, there has been a direct jump from the primary to the tertiary sector in terms of GDP share, bypassing a dominant manufacturing phase.

The correct answer is Both I and II.

Key Points

• A service in volleyball is the act of putting the ball into play by the right-back player, placed in the service zone. It is the only technical action where a player has total control over the ball without interference from teammates or opponents.
• Jump Serve (Jump and Serve): This is an advanced type of serve where the player increases the power and height of the serve by jumping to hit the ball. The server tosses the ball high, takes a rhythmic approach, and strikes the ball in mid-air. This technique generates high velocity and a steep downward angle, making it difficult for the receiving team to pass. Hence, statement I is correct.
• Floating Serve (Floater): A floating serve is hit with very little to no spin. Because of the lack of rotation, the ball's path becomes unpredictable as it interacts with the air currents, causing it to "dance" or move suddenly to the left, right, or drop down. This makes it extremely challenging for the defensive players to track and handle accurately. Hence, statement II is correct.
• Both the Jump Serve and the Floating Serve are fundamental strategies used in modern competitive volleyball to gain an advantage right from the start of the rally.
• Hence, the correct answer is Both I and II.

Additional Information

• History of Volleyball:
• Volleyball was invented in 1895 by William G. Morgan, a physical education director at the YMCA in Holyoke, Massachusetts. It was originally called "Mintonette" and was designed as an indoor sport for businessmen who found basketball too vigorous.
• The game was added to the Olympic Games program for the first time during the 1964 Tokyo Olympics.
• Basic Rules and Court Dimensions:
• A standard volleyball court measures 18 meters in length and 9 meters in width. It is divided by a net into two 9m x 9m halves.
• The height of the net is 2.43 meters for men and 2.24 meters for women.
• Each team consists of 6 players on the court. A team is allowed a maximum of three hits to return the ball over the net.
• Common Volleyball Terminology:
• Ace: A serve that results directly in a point because it hits the floor untouched or the receiving team cannot keep it in play.
• Libero: A specialized defensive player who wears a different colored jersey and can substitute for any back-row player without notice to the officials.
• Dig: The act of preventing the ball from hitting the floor after an attack or spike by the opponent.
• Set: A tactical pass, usually the second contact, that directs the ball towards a hitter to spike it into the opponent's court.

Important Points

• Governing Body: The Fédération Internationale de Volleyball (FIVB) is the international governing body for all forms of volleyball. It was founded in 1947 and is headquartered in Lausanne, Switzerland.
• Variations of Serves: Besides jump and floating serves, players also utilize the Underhand Serve (often for beginners), the Overhand Serve, and the Topspin Serve (which rotates forward rapidly to drop quickly into the court).
• Scoring System: Modern volleyball uses the Rally Point System, where a point is scored on every single rally, regardless of which team is serving. Matches are typically played as the best of five sets, with the first four sets played to 25 points and the fifth set (if necessary) played to 15 points.

• Location: Situated at a high altitude in the Aravalli Range, the site provides a serene environment conducive to meditation and religious activities.
• Preservation: The complex is managed by the Seth Kalyanji Paramanandji Pedhi trust and remains a vital pilgrimage site for the Jain community worldwide.

The correct answer is The sum of the atomic masses of all atoms in a molecule.

Key Points

• The molecular mass of a substance is defined as the sum of the atomic masses of all the atoms present in a single molecule of that substance. Hence, option 3 is correct.
• It is the relative mass of a molecule compared to 1/12th of the mass of one carbon-12 atom.
• Calculation Method: To find the molecular mass, we multiply the atomic mass of each element by the number of its atoms in the chemical formula and then add the results. For example, in Water (H2O), the mass is (2 x 1u) + (1 x 16u) = 18u.
• The total number of atoms in a molecule is known as its atomicity, not its molecular mass. For instance, the atomicity of Phosphorus (P4) is 4. Hence, statement 1 is incorrect.
• The valency of an atom is its combining capacity. The sum of valencies is used to determine chemical formulas but does not represent the mass of the molecule. Hence, statement 2 is incorrect.
• The volume occupied by a molecule relates to its physical state and conditions like temperature and pressure, as described by Avogadro's Law, rather than its mass. Hence, statement 4 is incorrect.

Additional Information

• Atomic Mass Unit (u): Also known as the unified mass, it is the standard unit used for expressing atomic and molecular weights. It is exactly 1/12th the mass of an unbound neutral atom of carbon-12 at rest and in its ground state.
• Molar Mass: While molecular mass refers to the mass of a single molecule (in u), molar mass refers to the mass of one mole of the substance (6.022 x 10^23 molecules) and is expressed in grams per mole (g/mol). Numerically, molecular mass and molar mass are the same.
• Formula Unit Mass: This term is specifically used for ionic compounds (like NaCl or CaCl2) where the constituent particles are ions rather than discrete molecules. It is calculated the same way as molecular mass.
• Significance in Chemistry: Molecular mass is essential for stoichiometry calculations in chemical reactions, allowing scientists to calculate the exact proportions of reactants needed to produce a specific amount of product.
• Example Calculations:
• Carbon Dioxide (CO2): (1 x 12u) + (2 x 16u) = 44u.
• Methane (CH4): (1 x 12u) + (4 x 1u) = 16u.

Important Points

• Standard Reference: The current scale for atomic and molecular masses is based on Carbon-12, adopted by the IUPAC in 1961 to replace older scales based on Oxygen.
• Precision: Molecular mass can be determined with high precision using Mass Spectrometry, which measures the mass-to-charge ratio of ionized molecules.
• Dalton (Da): In biology and biochemistry, the unit Dalton is frequently used interchangeably with the unified atomic mass unit (u) to describe the mass of large organic molecules like proteins and DNA.
• Gram Molecular Mass: This is simply the molecular mass of a substance expressed in grams. For example, the gram molecular mass of Oxygen (O2) is 32g.

The correct answer is Both I and II.

Key Points

• In the realm of Indian Classical Music, specifically the Carnatic tradition, Gitam (also spelled Geetham) is recognized as the simplest type of musical composition. It is designed primarily for students who have moved past basic exercises to understand the melodic structure of a Raga. Hence, statement I is correct.
• A Gitam is characterized by its very simple construction. Unlike more complex forms like Kritis or Varnas, it does not have distinct sections like Pallavi, Anupallavi, and Charana. Instead, it features a continuous and melodious flow of music. Hence, statement II is correct.
• Hence, the correct answer is Both I and II.

Additional Information

• Structural Features of Gitam:
• The term Gitam literally translates to "song." In these compositions, the Sahitya (lyrics) and the Svara (notes) are given equal importance. There are no Sangatis (variations) or complex Gamaka (ornamentations) used, making it easy for beginners to perform.
• It is typically set to Madhyama Kala (medium tempo). The Sahitya often consists of praises for Gods and Goddesses, reflecting the Bhakti (devotional) essence of Indian music.
• Historical Significance:
• Purandara Dasa, widely revered as the Pitamaha (grandfather) of Carnatic music, is credited with standardizing the teaching methodology, which includes the Pillari Gitams.
• The Pillari Gitams are usually the first few songs taught to students and are composed in praise of Lord Ganesha, such as the famous "Sri Gananatha" in Raga Malahari.
• Types of Gitams:
• Samanya Gitam: Also known as Sanchari Gitam, these are ordinary compositions where the Sahitya is religious or philosophical.
• Lakshana Gitam: These are unique because the Sahitya describes the Lakshanas (characteristics) of the Raga itself, including its Arohana (ascending scale), Avarohana (descending scale), and Varjya notes.

Important Points

• Musical Components:
• Tala: Gitams are usually set to simple Suladi Sapta Talas like Rupaka, Triputa, Dhruva, and Matya.
• Language: The lyrics are commonly found in Sanskrit, Kannada, or a specialized musical dialect known as Bhandira Bhasha.
• Pedagogical Role: Learning Gitams is a crucial milestone for a student to grasp the Svarupa (personality) of different Ragas like Kalyani, Sankarabharanam, or Mohanam before advancing to the Varnam stage.

The correct answer is '3' i.e. It was believed that he was innocent.

Key Points

• The given sentence is in the active voice: "People believed that he was innocent."
• To convert this sentence into the passive voice, the following changes are required:
• The object of the active sentence ("that he was innocent") becomes the subject of the passive sentence.
• The verb "believed" is changed to its passive form "was believed."
• The subject of the active sentence ("People") is either omitted (as it's a general reference) or retained in a prepositional phrase starting with "by."
• Therefore, the correct passive voice conversion is: "It was believed that he was innocent."

Correct sentence: It was believed that he was innocent.

Additional Information

• Key rules for converting active to passive voice:
• The object of the active voice becomes the subject in the passive voice.

Correct sentence: Weren't all the employees informed about the new rule by the manager?

Additional Information

• Option 2: "Wasn't all the employees informed about the new rule by the manager?" is incorrect because "employees" is plural, so the correct auxiliary verb should be "Weren't," not "Wasn't."
• Option 3: "Didn't all the employees informed about the new rule by the manager?" is incorrect because "informed" is not used correctly as a past participle in the passive voice.
• Option 4: "Doesn't all the employees informed about the new rule by the manager?" is incorrect because it mixes present tense ("Doesn't") with past participle "informed," which is grammatically wrong.

The correct answer is '3' i.e. Please come early tomorrow.

• Options 1, 2, and 4 are either grammatically incorrect or do not match the tone and intent of the original sentence.

Correct sentence: Please come early tomorrow.

Additional Information

• Passive to Active Voice Conversion Tips:
• Identify the subject performing the action in the passive sentence.
• Rewrite the sentence so that the subject appears at the beginning, performing the action.
• Use appropriate verbs and maintain the tone of the original sentence (e.g., polite requests should remain polite).
• Examples:
