Prime Factorization of the numbers:

 

 

The prime factors involved are 2, 3, and 5.

The highest power of 2 is 2³ = 8.

The highest power of 3 is 3¹ = 3.

The highest power of 5 is 5² = 25.

LCM calculation:

LCM = 2³ × 3¹ × 5²

LCM = 8 × 3 × 25

LCM = 24 × 25

LCM = 600

The smallest positive integer that is divisible by 25, 30, and 40 is 600.

Hence, the correct answer is “Option 4”.

Given:

Price of grapes = ₹15 per kg 

Price of oranges = ₹10 per kg

Earnings from Grapes = 200 × 15 = ₹3,000

Earnings from Oranges = 100 × 10 = ₹1,000

Total Earnings = Earnings from Grapes + Earnings from Oranges

Total Earnings = 3,000 + 1,000 = ₹4,000

Hence, the correct answer is “Option 2”.

Given:

1. Anita is younger than Bhavna but older than Charu. 

Bhavna > Anita > Charu.

2. Deepa is older than Bhavna but younger than Ekta

Ekta > Deepa > Bhavna.

Combining the two relationships to form a single chain:

Ekta > Deepa > Bhavna > Anita > Charu

From this combined chain, it is clear that Ekta is older than Deepa, Bhavna, Anita, and Charu.

Therefore, Ekta is the oldest among them.

Hence, the correct answer is ‘Option 4’.

Logic followed here is,

15 × 2 + 2 = 30 + 2 = 32

32 × 3 + 3 = 96 + 3 = 99

The correct answer is B.N. Rau.

Key Points

• Sir Benegal Narsing Rau was appointed as the Constitutional Advisor to the Constituent Assembly in 1946 to assist in the democratic transition and legal structuring of independent India.
• He was responsible for preparing the initial draft of the Constitution of India in October 1947, which originally contained 243 articles and 13 schedules.
• To formulate the framework, B.N. Rau traveled to the USA, Canada, Ireland, and the United Kingdom to consult with constitutional experts and jurists, including Justice Felix Frankfurter of the US Supreme Court.
• The Drafting Committee, led by Dr. B.R. Ambedkar, utilized B.N. Rau’s preliminary draft as the base document to refine and finalize the ultimate text of the Constitution.
• Beyond his work in India, he was an eminent jurist who also assisted in drafting the Constitution of Burma (Myanmar) in 1947 and served as a judge at the International Court of Justice in The Hague.

 Additional Information

• Alladi Krishnaswami Ayyar:
• An eminent lawyer and former Advocate General of the Madras State.
• He served as a key member of the Drafting Committee and played a vital role in shaping the provisions related to Fundamental Rights.
• T.T. Krishnamachari:
• A prominent businessman and politician who was inducted into the Drafting Committee in 1948.

• K.M. Munshi:
• Kanaiyalal Maneklal Munshi was a lawyer and independence activist who was a member of the Drafting Committee.
• He is also known for founding the Bharatiya Vidya Bhavan in 1938 to promote Indian culture and education.

The correct answer is Administrators appointed by the President.

Key Points

• According to Article 239(1) of the Constitution of India, every Union Territory is administered by the President. This administration is conducted through an Administrator appointed by the President with a designation he specifies.
• The Administrator of a Union Territory is an agent of the President and not a constitutional head of state like a Governor. This ensures the Central Government maintains direct executive control over these specific administrative units.
• The designation of the head varies: it is Lieutenant Governor for Delhi, Puducherry, Andaman and Nicobar Islands, Jammu and Kashmir, and Ladakh. In other territories like Chandigarh, Lakshadweep, and Dadra and Nagar Haveli and Daman and Diu, the title used is Administrator.
• Even in Union Territories with a Legislative Assembly and a Council of Ministers (like Delhi and Puducherry), the President remains the ultimate authority, exercising power through the Lieutenant Governor.

 Additional Information

• Constitutional Framework:
• Part VIII of the Constitution (Articles 239 to 241) specifically deals with the Union Territories. These units were created under the 7th Constitutional Amendment Act of 1956 and the States Reorganisation Act.
• Article 240 empowers the President to make regulations for the peace, progress, and good government of certain territories, which have the same legal force as an Act of Parliament.
• Parliament and State Entities:
• Parliament: Under Article 246(4), Parliament has the power to legislate on any subject, including those in the State List, for the Union Territories, but it does not directly administer them.
• Governors: Governors are appointed for States under Article 153. While the President can appoint a Governor of a state as an Administrator of an adjoining Union Territory under Article 239(2), their roles remain legally distinct.
• Chief Ministers: They exist only in Union Territories where Parliament has created a Legislative Assembly (e.g., Delhi under Article 239AA and Puducherry).

The correct answer is Harvest festivals and religious ceremonies.

Key Points

• The Santhal dance is a vibrant and ancient folk dance performed by the Santhal tribe, which is one of the largest Scheduled Tribes in India, primarily settled in Jharkhand, West Bengal, Odisha, and Bihar.
• This traditional dance is deeply connected to the agrarian lifestyle of the community and is predominantly performed during harvest festivals to express gratitude to the gods and nature for a successful yield.
• The most significant occasion for this dance is the Sohrai festival, celebrated in the month of October or November (after the Kharif harvest), where men and women dance together to the rhythmic beats of traditional drums.
• It is also performed during religious ceremonies such as Baha (the flower festival), which marks the spring season and the arrival of the Sal blossoms, honoring the supreme deity Marang Buru.
• The dance movements are characterized by synchronized steps where dancers form semi-circles or lines, often holding hands or waist-to-waist, symbolizing communal harmony and social cohesion.

 Additional Information

• Santhal Musical Instruments:
• Madal: A traditional two-headed drum made of clay or wood, which serves as the primary rhythmic heartbeat of the dance.
• Tiriao: A bamboo flute used to provide melodic accompaniment to the percussion.
• Dhamsa: A large kettle drum used to add depth and intensity to the performance.
• Santhal Tribe Heritage:
• They follow the Sarna religion, which is based on the worship of nature spirits and sacred groves known as Jaher.
• Their language, Santhali, is written in the Ol Chiki script, which was developed by Pandit Raghunath Murmu in 1925.
• Other Festivals:
• Karam Festival: Observed to seek blessings for the protection of crops and the well-being of the family.
• Erok-Sim: A ritual ceremony performed during the sowing of seeds at the start of the monsoon.

The correct answer is Weddings and festivals.

Key Points

• Tippani dance is a prominent folk dance originating from the Saurashtra region of Gujarat, particularly associated with the coastal towns of Chorwad and Veraval.
• The dance is traditionally performed by the women of the Koli and Bhil communities, who originally developed these rhythmic movements while working as laborers to level the ground during the construction of houses and forts.
• While it has its roots in manual labor, the performance has evolved into a celebratory art form conducted during significant social and cultural events, such as weddings and major Hindu festivals like Holi and Diwali.
• The performance is characterized by the use of the Tippani stick, a long wooden pole roughly 175 cm in length with a heavy square wooden or iron block (called a Garbo) attached at the base to strike the floor.
• The dancers arrange themselves in two rows and strike the floor in a synchronized, rhythmic pattern, creating a unique sound that serves as both music and a display of physical coordination and endurance.

 Additional Information

• Instruments and Music:
• The rhythmic thumping of the Tippani is accompanied by folk instruments like the Zanz, Manjira (cymbals), Tabla, and Dhol (drum) to maintain a steady tempo.
• The Turi and Shehnai are also frequently used to provide melodic accompaniment to the percussive nature of the dance.
• Cultural Context:
• Unlike purely Religious rituals that are confined to temples, Tippani is a social dance that brings the community together in public squares or household courtyards.
• The costumes worn are traditional Gujarati attire, including the Ghagra-Choli for women, often embellished with mirrors and vibrant embroidery typical of the Saurashtra folk style.
• It is often compared to other work-related folk dances, but it stands out due to its high energy and the percussive floor-striking technique which is rare in other Indian folk traditions.

The correct answer is Central India.

Key Points

• The Satpura Range is a major mountain system located in Central India, forming a significant part of the Indian peninsula's geographic backbone.
• Geographically, it extends in an east-west direction across the states of Gujarat, Maharashtra, Madhya Pradesh, and Chhattisgarh.
• The range is situated between two major west-flowing rivers: the Narmada River to the north and the Tapti River to the south.
• It runs parallel to the Vindhya Range, and together they create a natural divide between the Indo-Gangetic Plain of Northern India and the Deccan Plateau of the south.
• The name 'Satpura' is derived from the Sanskrit words 'Sapta' (seven) and 'Pura' (mountains), signifying the seven folds or hills that constitute the range.

 Additional Information

• Geological Characteristics:
• The Satpura Range is classified as a block mountain (horst), formed due to tectonic activity that created rift valleys (graben) on either side.
• The range is composed primarily of basaltic rocks in the west, while its eastern sections are made of Gondwana formations and metamorphic rocks.
• Highest Peak and Sub-ranges:
• Dhupgarh, located in the Mahadeo Hills near the hill station of Pachmarhi, is the highest peak of the Satpura Range, standing at 1,350 meters.
• The range includes several distinct hilly tracts such as the Rajpipla Hills, Gawilgarh Hills, and the Maikal Range.
• River Systems and Biodiversity:
• The Amarkantak Plateau, where the Satpura and Vindhya ranges meet, is the source of the Narmada and Son rivers.
• The range is home to rich deciduous forests and famous tiger reserves, including Kanha National Park, Satpura National Park, and Pench National Park.

The correct answer is West Bengal.

Key Points

• The Ganga-Brahmaputra Delta, also known as the Sunderbans Delta or the Bengal Delta, is the largest river delta in the world, covering an area of approximately 100,000 square kilometers.
• In the Indian subcontinent, this deltaic region is primarily situated in the state of West Bengal and the neighboring country of Bangladesh.
• The delta is formed by the confluence of the Ganga (Padma) and the Brahmaputra (Jamuna) rivers as they discharge their sediment-laden waters into the Bay of Bengal.
• It is renowned for the Sundarbans, a vast mangrove forest ecosystem that is a UNESCO World Heritage Site and the primary habitat of the Royal Bengal Tiger.
• The region is characterized by high alluvial fertility, making it one of the most productive agricultural zones in South Asia, supporting large populations.

 Additional Information

• Uttar Pradesh:
• This state lies in the Upper and Middle Ganga Plains. While the Ganga flows through it, the river is in its youthful and mature stages here, far from the deltaic formation at the river mouth.
• Bihar:
• Located in the Middle Ganga Plain, Bihar acts as a major drainage basin for the Ganga and its tributaries like the Gandak and Kosi, but it is a landlocked state located upstream of the delta.
• Assam:
• Assam is the primary valley for the Brahmaputra River in India. Although the river carries massive amounts of silt through this state, the actual delta formation begins only after the river enters Bangladesh and meets the Ganga.
• Geographical Features:
• The delta is a prograding delta, meaning it is still expanding into the sea due to the heavy sediment load deposited by the rivers.
• It features a complex network of distributaries, estuaries, and tidal creeks that are critical for local fisheries and transport.

The correct answer is Shankar Dayal Sharma.

The correct answer is Education, Income, Life expectancy.

Key Points

• The Human Development Index (HDI) is a composite statistical tool used to measure a country's overall achievement in its social and economic dimensions, shifting the focus from purely economic growth to human-centric development.
• It was created by Pakistani economist Mahbub ul Haq and Indian Nobel laureate Amartya Sen and has been published annually by the United Nations Development Programme (UNDP) since 1990.
• The index is calculated using three basic dimensions: a Long and healthy life, Knowledge, and a Decent standard of living.
• The Health dimension is assessed by Life expectancy at birth, which serves as a proxy for the quality of a nation's healthcare system, nutrition, and environmental safety.
• The Knowledge or Education dimension is measured through a combination of the Mean years of schooling for adults aged 25 years and older and the Expected years of schooling for children of school-entering age.
• The Standard of Living is quantified using Gross National Income (GNI) per capita adjusted for Purchasing Power Parity (PPP) in US dollars to account for differences in the cost of living across countries.

 Additional Information

• Methodology and Scoring:
• HDI values range between 0 and 1; a score closer to 1 indicates a higher level of human development.
• Countries are categorized into four tiers: Very High (0.800 and above), High (0.700–0.799), Medium (0.550–0.699), and Low Human Development (below 0.550).
• The final index is the geometric mean of the normalized indices for each of the three dimensions, ensuring that poor performance in one area is not masked by high performance in another.
• Extended Indices:
• To address criticisms of the HDI, the UNDP introduced the Inequality-adjusted HDI (IHDI) in 2010 to account for how achievements are distributed among the population.
• Other related metrics include the Gender Inequality Index (GII), which measures gender-based disadvantages, and the Multidimensional Poverty Index (MPI), which identifies overlapping deprivations.
• While Gross Domestic Product (GDP) measures economic output, HDI is considered a more holistic indicator as it incorporates social indicators like literacy and longevity.

The correct answer is Greater tilt increases seasonal contrast.

Key Points

• Axial tilt, also known as obliquity, is the angle between Earth's rotational axis and its orbital plane, currently measuring approximately 23.5 degrees.
• The tilt fluctuates between 22.1 degrees and 24.5 degrees over a cycle of roughly 41,000 years, a phenomenon identified by Serbian scientist Milutin Milankovitch.
• When the tilt is at its maximum (24.5 degrees), each hemisphere receives more direct solar radiation during its summer and significantly less during its winter, which increases seasonal contrast.
• A greater tilt results in hotter summers and colder winters because the higher latitudes are oriented more directly toward or away from the Sun during solstices.
• Conversely, a minimum tilt of 22.1 degrees leads to milder seasons; cooler summers in this phase often prevent winter snow from melting entirely, facilitating the growth of ice sheets and triggering glaciation.

 Additional Information

• Milankovitch Cycles include two other primary variations:
• Eccentricity: This refers to the shape of Earth's orbit around the Sun, which shifts from nearly circular to mildly elliptical over 100,000-year and 400,000-year cycles, affecting the total insolation received.
• Precession: Often called the Earth's 'wobble', this 26,000-year cycle changes the orientation of the axis, determining which hemisphere is tilted toward the Sun at perihelion (closest approach) or aphelion (farthest point).
• Orbital Speed: The speed at which Earth travels is governed by Kepler's Second Law and is influenced by eccentricity (distance from the Sun), not the tilt of the axis.
• Magnetic Field: Earth's magnetism is generated by the geodynamo effect in the outer core and is independent of the orbital obliquity cycles.

The correct answer is Indo-French Colonial.

Key Points

• The French Quarter of Puducherry, historically known as Ville Blanche (White Town), is globally recognized for its Indo-French Colonial architecture, a unique blend of 18th-century European designs and local Indian structural adaptations.
• The area is characterized by a Cartesian grid street layout, a common feature of French urban planning, where streets intersect at right angles, providing an organized and airy atmosphere.
• Buildings typically feature high compound walls and monumental arched gateways that lead into private courtyards, which were designed to provide privacy and natural cooling in a tropical climate.
• The aesthetic is defined by lime-plastered walls painted in a palette of yellow ochre, mustard, and white, which reflect the sunlight and help maintain a cooler internal temperature.
• Architectural details include tall windows with wooden louvered shutters (persiennes), wide verandahs, and ornamental cornices, showcasing a synthesis of French elegance and practical regional design.

 Additional Information

• Gothic Revival:
• While not the primary style of the quarter, it is seen in religious landmarks like the Basilica of the Sacred Heart of Jesus, featuring pointed arches and stained glass.
• Neoclassical Style:
• This style influenced many institutional buildings in Pondicherry, such as Raj Nivas and the Old Court Building, characterized by columns, pediments, and symmetrical facades.
• Tamil Quarter (Ville Noire):
• Located across the Canal, this area features vernacular Tamil architecture with Thinnais (raised street porches) and carved wooden pillars, which occasionally adopted French decorative motifs over time.
• Preservation:
• The INTACH (Indian National Trust for Art and Cultural Heritage) has played a significant role in restoring these colonial heritage buildings to maintain the city's historical identity.

The correct answer is constellation.

Key Points

• Orion is one of the most prominent and recognizable constellations in the night sky, characterized by its location on the celestial equator, which makes it visible globally.
• Named after a giant hunter in Greek mythology, it is commonly referred to as The Hunter and is listed as one of the 88 modern constellations defined by the International Astronomical Union (IAU).
• The constellation is most easily identified by Orion's Belt, an asterism formed by three bright stars: Alnitak, Alnilam, and Mintaka.
• It contains two of the ten brightest stars in the sky: Rigel (a blue supergiant) and Betelgeuse (a red supergiant).
• It also houses the Orion Nebula (M42), a massive region of dust and gas where new stars are being born, visible even to the naked eye as a fuzzy patch.

 Additional Information

• Star:
• A massive, luminous ball of plasma held together by gravity, undergoing nuclear fusion in its core. While Orion contains stars like Saiph and Bellatrix, the name Orion refers to the entire group.
• Planet:
• A celestial body that orbits a star, has sufficient mass for its self-gravity to make it spherical, and has cleared its neighborhood of other objects, such as Venus or Jupiter.
• Satellite:
• An object that orbits a planet or another body larger than itself. This includes natural satellites like the Moon and artificial satellites launched for telecommunications or research.

The correct answer is Involuntary action.

Key Points

• Involuntary actions are biological processes or movements that occur without the conscious control or will of an individual.
• The heartbeat is classified as an involuntary action because it is performed automatically by the body to ensure continuous blood circulation, requiring no deliberate thought.
• These functions are primarily regulated by the Autonomic Nervous System (ANS), which manages internal organ operations.
• The Medulla Oblongata, situated in the hindbrain, acts as the primary control center for regulating the heart rate, breathing, and blood pressure.
• The rhythmic contraction of the heart is initiated by the Sinoatrial (SA) node, often referred to as the natural pacemaker, located in the right atrium.

 Additional Information

• Reflex Action
• This is a rapid, spontaneous response to a stimulus, such as the knee-jerk reflex or blinking of eyes.
• It is usually controlled by the spinal cord to protect the body from immediate harm.
• Voluntary Action
• These actions are under the direct control of the cerebrum and involve conscious decision-making.
• Examples include writing, cycling, and dancing.
• Cardiac Muscles
• The heart is composed of unique striated muscles that are myogenic in nature, meaning they can initiate contraction without external nerve impulses.
• These muscles never fatigue, allowing the heart to beat approximately 72 times per minute throughout a person's lifetime.

The correct answer is Waste disposal.

Key Points

• Lysosomes are membrane-bound vesicular structures formed by the process of packaging in the Golgi apparatus.
• They serve as the waste disposal system of the cell by digesting foreign materials, such as bacteria and food, as well as worn-out cell organelles.
• These organelles contain a variety of hydrolytic enzymes (including lipases, proteases, and carbohydrases) that are capable of breaking down all major classes of biological macromolecules.
• The enzymes within a lysosome are optimally active at an acidic pH (approximately 4.5 to 5.0), which is maintained by proton pumps in the lysosomal membrane.
• In the event of cellular damage or malfunction, lysosomes may burst, leading to the autolysis or self-digestion of the cell; for this reason, they are famously known as the suicide bags of the cell.

 Additional Information

• Energy production:
• This is the primary role of the mitochondria, often referred to as the powerhouse of the cell.
• Mitochondria produce ATP (Adenosine Triphosphate) through the process of oxidative phosphorylation during cellular respiration.
• Protein synthesis:
• This process is carried out by ribosomes, which can be found floating freely in the cytoplasm or attached to the Rough Endoplasmic Reticulum (RER).
• The nucleolus within the nucleus is responsible for the synthesis of ribosomal RNA (rRNA).
• Storage of lipids:
• The Smooth Endoplasmic Reticulum (SER) is the major site for the synthesis and storage of lipids and steroid hormones.
• In specialized animal cells, lipids are stored in large quantities within adipocytes (fat cells) in the form of triglycerides.

The correct answer is Chilika Lake.

Key Points

• Chilika Lake, located in the state of Odisha on the eastern coast of India, is the largest brackish water lagoon in India and the second largest in the world.
• It spreads across the Puri, Khurda, and Ganjam districts at the mouth of the Daya River, covering an area that fluctuates between 900 and 1,165 square kilometers during different seasons.
• In 1981, it was designated as the first Indian wetland of international importance under the Ramsar Convention due to its rich biodiversity.
• The lake serves as a massive wintering ground for migratory birds traveling from the Caspian Sea, Lake Baikal, Aral Sea, and other remote regions of Central and South-East Asia.
• It is one of the few places in the world where the endangered Irrawaddy Dolphins can be spotted, particularly near the Satapada island area.

The correct answer is 1767-69.

Key Points

• The First Anglo-Mysore War was a major military conflict in India that took place between 1767 and 1769.
• It was fought between the Kingdom of Mysore, under the leadership of Hyder Ali, and the British East India Company.
• The war was preceded by a tripartite alliance formed in 1766 involving the British, the Nizam of Hyderabad, and the Marathas against Mysore.
• Hyder Ali successfully broke the alliance through strategic diplomacy, convincing the Marathas to withdraw and the Nizam to switch sides and support Mysore against the British.
• In a decisive move, Hyder Ali reached the outskirts of Madras (now Chennai), threatening the British headquarters and forcing them to negotiate.
• The conflict concluded with the signing of the Treaty of Madras on April 4, 1769, which was a defensive alliance ensuring the mutual return of conquered territories and assistance in case of a third-party attack.

 Additional Information

• The struggle for supremacy in South India continued through three more wars:
• Second Anglo-Mysore War (1780-1784): Sparked by the British capture of Mahe; it ended with the Treaty of Mangalore after the death of Hyder Ali.
• Third Anglo-Mysore War (1790-1792): Fought between Tipu Sultan and the British under Lord Cornwallis, resulting in the Treaty of Seringapatam and Mysore losing half its territory.
• Fourth Anglo-Mysore War (1799): Initiated by Lord Wellesley, this final conflict ended with the fall of Seringapatam and the death of Tipu Sultan, leading to the restoration of the Wodeyar dynasty under British Subsidiary Alliance.

Shortcut Trick

Use the ratio relationship: Illumination (I) ∝ Power (P) / Distance² (d²)

I₂ / I₁ = (P₂ / P₁) × (d₁ / d₂)²

I₂ / 15 = (100 / 60) × (2 / 3)²

I₂ / 15 = (5 / 3) × (4 / 9) ⇒ I₂ = 15 × 20 / 27 = 300 / 27

I₂ = 11.11 lux

∴ The correct answer is 11.11 lux.

Alternate Method

Given:

Initial Power (P₁) = 60 W, Distance (d₁) = 2 m, Illumination (I₁) = 15 lux

Final Power (P₂) = 100 W, Distance (d₂) = 3 m

Formula Used:

I = k × (P / d²), where k is the proportionality constant.

Step 1: Find the value of k from the first condition

⇒ 15 = k × (60 / 2²)

⇒ 15 = k × (60 / 4)

⇒ 15 = k × 15

⇒ k = 1

Step 2: Find the illumination for the second condition

⇒ I₂ = k × (P₂ / d₂²)

⇒ I₂ = 1 × (100 / 3²)

⇒ I₂ = 100 / 9

⇒ I₂ = 11.111...

∴ The correct answer is 11.11 lux.

Shortcut Trick

Given Sum of Diagonals (d₁ + d₂) = 62 cm and Area = 336 cm².

Relationship between Side (a) and Diagonals: 4a² = d₁² + d₂².

We know (d₁ + d₂)² = d₁² + d₂² + 2d₁d₂ = 4a² + 4 × Area.

62² = 4a² + 4 × 336 ⇒ 3844 = 4a² + 1344.

4a² = 2500 ⇒ a² = 625 ⇒ a = 25 cm.

∴ The correct answer is 25 cm.

Alternate Method

Given:

Sum of diagonals (d₁ + d₂) = 62 cm

Area of rhombus = 336 cm²

Formula Used:

Area of Rhombus = (1/2) × d₁ × d₂

Side of Rhombus (a) = √[(d₁/2)² + (d₂/2)²]

Calculations:

⇒ Area = (1/2) × d₁ × d₂ = 336

⇒ d₁ × d₂ = 672

⇒ We know: (d₁ + d₂)² = d₁² + d₂² + 2d₁d₂

⇒ 62² = d₁² + d₂² + 2(672)

⇒ 3844 = d₁² + d₂² + 1344

⇒ d₁² + d₂² = 3844 − 1344 = 2500

⇒ For a rhombus, 4a² = d₁² + d₂²

⇒ 4a² = 2500

⇒ a² = 2500 ÷ 4 = 625

⇒ a = √625 = 25 cm

∴ The correct answer is 25 cm.

In a parallelogram, the sum of adjacent angles is always 180°.

Total ratio parts = 1 + 3 = 4 units.

4 units ⇒ 180°

1 unit ⇒ 180° ÷ 4 = 45°

Larger angle (3 units) ⇒ 3 × 45° = 135°.

∴ The correct answer is 135°.

Alternate Method

Given:

Ratio of adjacent angles = 1 : 3

Formula used:

Sum of adjacent angles in a parallelogram = 180° (Supplementary angles property)

Let the two adjacent angles be 1x and 3x.

⇒ 1x + 3x = 180°

⇒ 4x = 180°

⇒ x = 180° ÷ 4

⇒ x = 45°

⇒ Smaller angle = 1 × 45° = 45°

⇒ Larger angle = 3 × 45° = 135°

∴ The correct answer is 135°.

Additional Information

Properties of a Parallelogram

Shortcut Trick

Simplify all fractions to their lowest terms before calculation.

4/7 is already in simplest form.

8/14 → 4/7 (dividing by 2) and 12/21 → 4/7 (dividing by 3).

Since all fractions are now 4/7, their LCM is 4/7.

∴ The correct answer is 4/7.

Alternate Method

Given Fractions: 4/7, 8/14, and 12/21

Formula Used: LCM of Fractions = LCM of Numerators ÷ HCF of Denominators (applied to simplified fractions)

⇒ First, reduce all fractions to their simplest forms:

⇒ Fraction 1 = 4/7

⇒ Fraction 2 = 8/14 = (8 ÷ 2) / (14 ÷ 2) = 4/7

⇒ Fraction 3 = 12/21 = (12 ÷ 3) / (21 ÷ 3) = 4/7

⇒ Now, find the LCM of (4/7, 4/7, 4/7):

⇒ LCM = LCM of (4, 4, 4) ÷ HCF of (7, 7, 7)

⇒ LCM = 4 ÷ 7 = 4/7

∴ The correct answer is 4/7.

Additional Information

LCM of Fractions Formula

LCM of fractions = LCM of Numerators ÷ HCF of Denominators. Ensure fractions are in their simplest form first.

HCF of Fractions Formula

HCF of fractions = HCF of Numerators ÷ LCM of Denominators. This is the inverse of the LCM rule.

Simplification Rule

Shortcut Trick

Ratio of numbers = 4 : 5

LCM of ratio parts 4 and 5 = 20 units

Given 20 units = 180 ⇒ 1 unit = 9

Sum of ratios = 4 + 5 = 9 units

Total Sum = 9 × 9 = 81

∴ The correct answer is 81.

Alternate Method

Given:

Ratio of two numbers = 4 : 5

LCM of the numbers = 180

Formula Used:

If two numbers are in the ratio a : b, then the numbers are ax and bx (where x is the HCF).

LCM (ax, bx) = a × b × x (if a and b are coprime).

Calculations:

⇒ Let the two numbers be 4x and 5x.

⇒ LCM of 4x and 5x = 4 × 5 × x = 20x

⇒ According to the question, 20x = 180

⇒ x = 180 ÷ 20

⇒ x = 9 (This is the HCF of the numbers)

⇒ First number = 4 × 9 = 36

⇒ Second number = 5 × 9 = 45

⇒ Sum of the numbers = 36 + 45 = 81

∴ The correct answer is 81.

Additional Information

Relation between LCM and HCF

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 × LCM.

HCF of Ratios

If numbers are in the ratio a : b, then the HCF is the common multiplier x that converts the ratio into actual values ax and bx.

Coprime Numbers

Two numbers are coprime if their HCF is 1. If ratio parts are simplified (like 4 and 5), they are always coprime.

Shortcut Trick

The ratio of the percentages is 30% : 120% = 1 : 4.

Given that 1 part (representing 30%) is equal to 90.

To find 4 parts (representing 120%), we calculate: 4 × 90 = 360.

∴ The correct answer is 360.

Alternate Method

Given: 30% of a number is 90.

Formula: Value = (Total Number × Percentage) ÷ 100

⇒ Let the number be x.

⇒ 30% × x = 90

⇒ (30 ÷ 100) × x = 90

⇒ x = (90 × 100) ÷ 30

⇒ x = 300

⇒ Now, find 120% of the number 300:

⇒ 120% of 300 = (120 ÷ 100) × 300

⇒ 1.2 × 300 = 360

∴ The correct answer is 360.

Additional Information

Unitary Method in Percentage

If p% of a number is 'a', then 1% is a ÷ p, and q% is (a ÷ p) × q.

Percentage to Decimal Conversion

To convert a percentage to a decimal, divide by 100 (e.g., 120% = 120 ÷ 100 = 1.2).

Percentage of a Number

The formula to find p% of x is (p ÷ 100) × x.

Shortcut Trick

Convert percentages into fractions: 40% = 2/5 and 80% = 4/5.

Required value = (2/5) × (4/5) × (5/8) × 4800

Simplify fractions first: (4/5) × (5/8) = 1/2. Then (2/5) × (1/2) = 1/5.

Final calculation: 1/5 × 4800 = 960.

∴ The correct answer is 960.

Alternate Method

Given: Initial value = 4800, fractional part = 5/8, percentages = 80% and 40%.

Formula Used: Final Value = P₁% × P₂% × Fraction × Total Value

⇒ Step 1: Calculate 5/8 of 4800

⇒ (5/8) × 4800 = 5 × 600 = 3000

⇒ Step 2: Calculate 80% of the result

⇒ 80% of 3000 = (80/100) × 3000 = 0.8 × 3000 = 2400

⇒ Step 3: Calculate 40% of the result

⇒ 40% of 2400 = (40/100) × 2400 = 0.4 × 2400 = 960

∴ The correct answer is 960.

Additional Information

The 'Of' Operator

In mathematical expressions, 'of' functions as a multiplication sign and should be prioritized according to BODMAS/VBODMAS rules.

Percentage to Fraction Chart

Memorizing common equivalents helps in quick calculations: 20% = 1/5, 40% = 2/5, 60% = 3/5, 80% = 4/5, and 12.5% = 1/8.

Commutative Property of Multiplication

The order of multiplication does not affect the result. Therefore, (40% of 80% of 5/8) is identical to (5/8 of 40% of 80%).

Shortcut Trick

Ratio of Cost Price (CP) to Selling Price (SP) is the inverse of their percentage coefficients.

CP : SP = 50 : 40 = 5 : 4

Since CP (5) > SP (4), there is a Loss of 1 unit.

Loss % = (Loss ÷ CP) × 100 = (1 ÷ 5) × 100 = 20%

∴ The correct answer is 20%.

Alternate Method

Given: 40% of CP = 50% of SP

Formula: Loss % = [(CP − SP) ÷ CP] × 100

⇒ 40 ÷ 100 × CP = 50 ÷ 100 × SP

⇒ 4 × CP = 5 × SP

⇒ SP ÷ CP = 4 ÷ 5

⇒ Let CP = 5 and SP = 4

⇒ Loss = 5 − 4 = 1

⇒ Loss % = (1 ÷ 5) × 100 = 20%

∴ The correct answer is 20%.

Additional Information

Profit and Loss Basics

Profit occurs when Selling Price (SP) > Cost Price (CP). Profit % = [(SP − CP) ÷ CP] × 100.

Inverse Ratio Property

If x% of A = y% of B, then the ratio A : B = y : x. This is a common shortcut for comparison-based problems.

Marked Price and Discount

Discount is always calculated on the Marked Price (MP). SP = MP × (100 − Discount%) ÷ 100.

Shortcut Trick

Profit is 30% on Selling Price (SP) ⇒ Profit : SP = 30 : 100 = 3 : 10

Since Cost Price (CP) = SP − Profit, then CP = 10 − 3 = 7 units

Profit percentage on CP = (Profit ÷ CP) × 100

Profit % = (3 ÷ 7) × 100 = 42.857...% ≈ 42.86%

∴ The correct answer is 42.86 percent.

Alternate Method

Given: Profit on Selling Price = 30%

Formula Used: Profit % on Cost Price = [Profit ÷ (Selling Price − Profit)] × 100

⇒ Let the Selling Price (SP) = 100

⇒ Profit earned = 30% of 100 = 30

⇒ Cost Price (CP) = SP − Profit = 100 − 30 = 70

⇒ Profit Percentage on Cost Price = (Profit ÷ CP) × 100

⇒ Profit % = (30 ÷ 70) × 100

⇒ Profit % = 300 ÷ 7 = 42.857...

⇒ Profit % ≈ 42.86%

∴ The correct answer is 42.86 percent.

Additional Information

Profit Percentage Comparison

Profit % on Cost Price is always numerically higher than Profit % on Selling Price because the denominator (CP) is smaller than SP.

Direct Conversion Rule

If profit on SP is x%, then Profit % on CP = [x ÷ (100 − x)] × 100.

Loss on Selling Price

If loss on SP is y%, then Loss % on CP = [y ÷ (100 + y)] × 100.

Shortcut Trick

Efficiency ratio of R : S = 140 : 100 = 7 : 5.

Time ratio is inversely proportional ⇒ R : S = 5 : 7.

Given S takes 35 days (7 units = 35 days ⇒ 1 unit = 5 days).

Time for R alone = 5 units × 5 = 25 days.

∴ The correct answer is 25 days.

Alternate Method

Given:

Time taken by S = 35 days.

R is 40% more efficient than S.

Formula used:

Total Work = Efficiency × Time

Calculations:

Let the Efficiency of S be 1 unit/day.

⇒ Total Work = 1 × 35 = 35 units.

⇒ Efficiency of R = 1 + 40% of 1 = 1.4 units/day.

⇒ Time taken by R = Total Work ÷ Efficiency of R

⇒ Time for R = 35 ÷ 1.4

⇒ Time for R = 350 ÷ 14 = 25 days.

∴ The correct answer is 25 days.

Additional Information

Efficiency and Time Relation

Efficiency is inversely proportional to the time taken to complete a task. If efficiency ratio is a : b, then time ratio is b : a.

Work and Wages

In most competitive exams, wages are distributed in the ratio of the total work done by each individual, which depends on their efficiency and time spent.

Percentage Conversion

To increase a value by x%, multiply the base value by (100 + x) ÷ 100. Here, 40% more means a multiplier of 1.4.

Shortcut Trick

Total hours for R = 10 × 3 = 30 hr | Total hours for S = 6 × 5 = 30 hr.

Since both take 30 hours, their combined time = 30 ÷ 2 = 15 hours.

To finish the work in 4 days, hours per day = 15 ÷ 4 = 3.75 hours.

∴ The correct answer is 3.75 hours.

Alternate Method

Given: R works 10 days (3 hr/day) | S works 6 days (5 hr/day) | Target duration = 4 days.

Formula Used: Total Work = Efficiency × Total Time (in hours).

⇒ Total hours for R = 10 × 3 = 30 hr

⇒ Total hours for S = 6 × 5 = 30 hr

⇒ LCM of (30, 30) = 30 units (Total Work)

⇒ Combined Efficiency of (R + S) = 1 + 1 = 2 units/hr

⇒ Total time needed together = 30 ÷ 2 = 15 hours

⇒ Hours per day needed for 4 days = 15 ÷ 4 = 3.75 hours/day

∴ The correct answer is 3.75 hours.

Additional Information

Work and Wages

Wages are always distributed in the ratio of the actual work done by each person, which is (Efficiency × Time).

Combined Efficiency Rule

If two people take 'a' and 'b' hours respectively, they complete the work together in (a × b) ÷ (a + b) hours.

Inverse Proportion

For a constant amount of work, the time taken is inversely proportional to the efficiency of the worker.

Shortcut Trick

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

Speed = 216 × (5/18)

Speed = 12 × 5 = 60 m/s

∴ The correct answer is 60 m/s.

Alternate Method

Given: Speed of the car = 216 km/hr

Formula Used: Speed = Distance ÷ Time

⇒ Distance in 1 hour = 216 km = 216 × 1000 = 216000 meters ⇒ Time taken = 1 hour = 60 × 60 = 3600 seconds ⇒ Speed = 216000 ÷ 3600 ⇒ Speed = 2160 ÷ 36 ⇒ Speed = 60 m/s

∴ The correct answer is 60 m/s.

Additional Information

Speed Conversion Factors

To convert km/hr to m/s, multiply by 5/18. To convert m/s to km/hr, multiply by 18/5.

Average Speed

Average Speed = Total Distance ÷ Total Time. If a car travels equal distances at speeds x and y, Average Speed = (2 × x × y) ÷ (x + y).

Relative Speed

When two objects move in opposite directions, their relative speed is the sum (S₁ + S₂); in the same direction, it is the difference (S₁ − S₂).

Shortcut Trick

Speed ratio (Usual : New) = 100% : 40% = 5 : 2.

Since distance is constant, Time ratio is the inverse of speed ratio = 2 : 5.

Difference in time parts = 5 − 2 = 3 units.

Given, 3 units = 15 min ⇒ 1 unit = 5 min.

Usual time = 2 units = 2 × 5 = 10 min.

∴ The correct answer is 10 min.

Alternate Method

Given:

New speed = 40% of Usual speed.

Time delay = 15 minutes.

Formula Used:

Distance = Speed × Time

Calculations:

⇒ Let Usual speed = S and Usual time = T.

⇒ New Speed = 40% of S = 0.4S.

⇒ New Time = T + 15 min.

⇒ Since Distance is same: S × T = 0.4S × (T + 15)

⇒ T = 0.4T + 6

⇒ T − 0.4T = 6

⇒ 0.6T = 6

⇒ T = 6 ÷ 0.6 = 10 min.

∴ The correct answer is 10 min.

Additional Information

Speed-Time Inverse Relationship

When Distance is constant, Speed (S) is inversely proportional to Time (T). Thus, S₁ × T₁ = S₂ × T₂ or S₁/S₂ = T₂/T₁.

Late and Early Concept

If a person is late by time t₁ in one case and late by t₂ in another, the time difference is |t₁ − t₂|. If one is late and one is early, the difference is t₁ + t₂.

Percentage to Ratio Shortcut

Always convert percentage speed to fractions (40% = 2/5). If speed becomes 2/5, then time must become 5/2 of the usual time.

Shortcut Trick

Initial ratio A : B = 7 : 5 (Difference = 2 units)

Final ratio A : B = 4 : 3. To equate differences, multiply by 2 → 8 : 6 (Difference = 2 units)

Increase in each part = 8 − 7 = 1 unit (for A) and 6 − 5 = 1 unit (for B)

Given 1 unit = 4

Initial value of B = 5 units = 5 × 4 = 20

∴ The correct answer is 20.

Alternate Method

Given: Initial ratio of A and B is 7 : 5. Increase in each number is 4. New ratio is 4 : 3.

Formula Used: Ratio → a : b can be written as ax and bx.

⇒ Let the numbers be 7x and 5x.

⇒ According to the question: (7x + 4) / (5x + 4) = 4 / 3

⇒ 3 × (7x + 4) = 4 × (5x + 4)

⇒ 21x + 12 = 20x + 16

⇒ 21x − 20x = 16 − 12

⇒ x = 4

⇒ Initial value of B = 5x = 5 × 4 = 20

∴ The correct answer is 20.

Additional Information

Concept of Ratio

A ratio a : b represents the relative size of two quantities. Multiplying both terms by the same constant k gives an equivalent ratio ak : bk.

Equating Differences

If the same value is added to or subtracted from both terms of a ratio, the absolute difference between the parts must be adjusted to be consistent across both ratios to solve using the unit method.

Proportionality Rule

If a/b = c/d, then by cross-multiplication, ad = bc. This is the fundamental property used to solve linear equations involving ratios.

Shortcut Trick

The difference in Selling Price is equal to the difference in Discount Percentages applied on the Marked Price.

Difference in discount % = 25% − 18% = 7%

Given, 7% of Marked Price = Rs. 70

1% of Marked Price = Rs. 10

⇒ 100% (Marked Price) = 10 × 100 = Rs. 1000

∴ The correct answer is Rs. 1000.

Alternate Method

Given:

Discount₁ = 25% | Discount₂ = 18% | Difference in SP = Rs. 70

Formula Used:

Selling Price (SP) = Marked Price (MP) × (100 − Discount%) ÷ 100

Calculations:

Let the Marked Price (MP) of the article be Rs. x.

⇒ SP₁ = x × (100 − 25) ÷ 100 = 0.75x

⇒ SP₂ = x × (100 − 18) ÷ 100 = 0.82x

⇒ Difference = SP₂ − SP₁ = 0.82x − 0.75x

⇒ 70 = 0.07x

⇒ x = 70 ÷ 0.07

⇒ x = 1000

∴ The correct answer is Rs. 1000.

Additional Information

Relationship between MP and CP

Marked Price (MP) ÷ Cost Price (CP) = (100 + Profit%) ÷ (100 − Discount%). This is used when both profit and discount percentages are known.

Successive Discounts

If two successive discounts of a% and b% are given, the single equivalent discount is (a + b − ab/100)%.

Net Profit after Discount

Profit = [MP × (100 − D%)/100] − CP. If SP is less than CP, it results in a loss.

Shortcut Trick

Quickly calculate the Discount ÷ Marked Price ratio for all options:

1. 200/1200 = 1/6 ≈ 16.67%

2. 300/1500 = 1/5 = 20%

3. 800/2300 = 8/23 ≈ 34.78%

4. 600/2200 = 3/11 ≈ 27.27%

Comparing the values, 34.78% is the highest.

∴ The correct answer is Selling price = Rs. 1500 and Marked price = Rs. 2300.

Alternate Method

Given: Selling Price (SP) and Marked Price (MP) for four different scenarios.

Formula Used: Discount % = [(MP − SP) ÷ MP] × 100

Calculating discount percentage for each case:

Case (1): MP = 1200, SP = 1000

⇒ Discount % = [(1200 − 1000) ÷ 1200] × 100 = (200 ÷ 1200) × 100 = 16.66%

Case (2): MP = 1500, SP = 1200

⇒ Discount % = [(1500 − 1200) ÷ 1500] × 100 = (300 ÷ 1500) × 100 = 20%

Case (3): MP = 2300, SP = 1500

⇒ Discount % = [(2300 − 1500) ÷ 2300] × 100 = (800 ÷ 2300) × 100 ≈ 34.78%

Case (4): MP = 2200, SP = 1600

⇒ Discount % = [(2200 − 1600) ÷ 2200] × 100 = (600 ÷ 2200) × 100 ≈ 27.27%

By comparison, Case (3) provides the highest discount percentage.

∴ The correct answer is Selling price = Rs. 1500 and Marked price = Rs. 2300.

Additional Information

Successive Discount Formula

For two successive discounts of x% and y%, the single equivalent discount is (x + y − xy/100)%.

Marked Price (List Price)

The price printed on the label of an article is called the Marked Price. Discounts are always computed on this value unless specified otherwise.

Relationship between MP and CP

The ratio of Marked Price to Cost Price is given by MP/CP = (100 + Profit%)/(100 − Discount%).

The correct answer is 'of'.

 

Key Points

• The preposition 'of' is used to indicate the material or substance that something is made from.
• We typically use 'made of' when the base material (in this case, wool) is still recognizable and has not undergone a significant chemical transformation.
• Since the blanket is physically composed of wool fibers, the phrase 'made of wool' is grammatically correct.

Therefore, the correct answer is Option 4.

 

Complete Sentence: 'Bibhu liked the blanket made of wool.'

 

Additional Information

• Made from: Used when the original material has been transformed into something else (e.g., Paper is made from wood).
• Made by: Used to specify the person, company, or process that created the object (e.g., The sweater was made by his grandmother).
• Made out: This is usually part of the phrasal verb 'made out of' or used in different contexts like 'making out a check'.

The correct answer is Will the organisers make the necessary arrangements before the festival starts?.

Key Points

• The given sentence is in the Passive Voice and follows the structure of an Interrogative Sentence in the Future Indefinite Tense (Simple Future).
• The passive construction for simple future interrogative is: Will/Shall + Object + be + V3 (Past Participle) + by + Subject?. Here, the object is the necessary arrangements and the subject (agent) is the organisers.
• To convert this into Active Voice, the structure must change to: Will/Shall + Subject + V1 (Base Form) + Object?.
• Applying this rule, the subject the organisers moves to the beginning after the auxiliary verb Will, and the main verb made reverts to its base form make.
• The phrase before the festival starts is a subordinate clause that remains unchanged during the voice transformation.
• Therefore, the active form is: Will the organisers make the necessary arrangements before the festival starts?.

 Additional Information

• Active vs. Passive Voice Rules:
• Active Voice: The subject performs the action (e.g., The organisers will make...).
• Passive Voice: The subject receives the action (e.g., Arrangements will be made...).
• In Future Indefinite, the auxiliary will is accompanied by be in the passive form, while the main verb always takes the third form (V3).
• Options using Do, Have, or Did are incorrect because they change the Tense of the sentence to Simple Present, Present Perfect, and Simple Past respectively.
• The auxiliary verb Will is used for third-person plural subjects like the organisers in modern English standard usage.

The correct answer is No one must leave the gate open..

Key Points

• The original sentence is in the Passive Voice, structured as: Object (The gate) + Modal (must) + Negative (not) + be + Past Participle (left) + Complement (open) + Preposition (by) + Agent (anyone).
• To transform a sentence into the Active Voice, the agent of the passive sentence (anyone) becomes the subject of the active sentence. In English grammar, when a negative statement involves not + anyone, it is conventionally expressed using the negative pronoun No one or Nobody as the subject.
• The Modal Verb (must) denotes a strong obligation or a strict prohibition. During voice conversion, the modal verb must remain unchanged to preserve the original mood and intensity of the instruction.
• In Active Voice constructions with modals, the auxiliary be is removed, and the Past Participle (V3) form of the verb (left) is converted back to its Base Form (V1), which is leave.
• The resulting Active Voice structure follows the pattern: Subject (No one) + Modal (must) + Verb in Base Form (leave) + Object (the gate) + Complement (open).

 Additional Information

• Voice and Modal Verbs:
• Active Structure: Subject + Modal + V1 + Object. For example, He must finish the work.
• Passive Structure: Object + Modal + be + V3 + (by + Subject). For example, The work must be finished by him.
• Negative Pronouns: Using No one at the beginning of a sentence is more concise and standard than using Anyone must not..., which is often considered grammatically weak or non-standard in formal English.
• Semantic Consistency: Changing must to should (as seen in some incorrect options) alters the meaning from a command/prohibition to a suggestion/advice, which violates the rules of transformation.
• Verb Tense: The transformation must maintain the simple aspect of the modal; introducing continuous forms like be leaving changes the temporal nature of the action.

The correct answer is 'over'.

 

Key Points

• The preposition 'over' is commonly used with the verb 'tripped' when someone stumbles because their foot hits an obstacle on the ground.
• In this sentence, the heap of garbage acts as the obstacle that caused Neha to lose her balance and fall.
• Using 'tripped over' correctly indicates the physical movement of catching one's foot on something and falling forward or down.

Therefore, the correct answer is Option 3.

 

Complete Sentence: 'Neha tripped over the heap of garbage and fell onto the floor.'

 

Additional Information

• Option 1: 'onto' is used to show movement to a position on a surface (e.g., she fell onto the floor). It does not fit the blank describing the cause of the trip.
• Option 2: 'against' implies contact or collision with a vertical surface or opposition, which is not the standard phrasing for stumbling over something on the ground.
• Option 4: 'by' usually indicates proximity (near) or the agent of an action, neither of which is appropriate for describing the object one stumbles upon.

The correct answer is aimed at bringing about.

Key Points

• The verb aimed is idiomatically followed by the preposition at when expressing a purpose or intention. When at is used as a preposition, it must be followed by a gerund (the -ing form of the verb), making aimed at bringing the grammatically correct structure.
• The phrasal verb bring about means to cause something to happen, to result in, or to initiate a change. In the context of economic reforms, the intended goal is to cause an increase or improvement in the productivity of the nation.
• The original phrase bringing up is contextually inappropriate as it primarily means to nurture/raise a child or to mention a specific topic during a conversation. It does not collocate with economic metrics like productivity.
• Option 1 is incorrect because aimed in is not a standard idiomatic expression for purpose, and bringing forward means to move a scheduled event to an earlier date or to present a proposal.
• Option 3 is incorrect because while aim for can be used with a noun, aimed at is the preferred and more formal construction when describing the objective of systemic reforms or policies followed by a verb.

 Additional Information

• Understanding Phrasal Verbs with Bring:
• Bring about: To make something happen, especially a major change or revolution.
• Bring up: To mention a subject or to rear children. Example: She was brought up in a small town.
• Bring forward: To introduce for discussion or to change the timing of a meeting to an earlier slot.
• Bring in: To introduce a new law, system, or legislation.
• Bring out: To produce or launch a new product, or to highlight a specific trait.

The correct answer is Option 2.

Key Points

• The paragraph tells a story about an old nobleman, his love interest, and his family's reaction.
• Sentence S1 is fixed: It introduces the grandfather (an old nobleman) who fell in love with his farmer's daughter.
• Sentence D follows S1: After the characters are introduced, the narrator mentions their personal connection to the story by stating, 'I knew them both' (referring to the grandfather and the girl).
• Sentence A is the third sentence: It provides a detailed physical and character description of the farmer's daughter mentioned in S1, describing her as blond, pale, and gentle like a Madonna.
• Sentence C is the fourth sentence: It describes the progression of the relationship, where the old nobleman took her to his home because he was so captivated by her.
• Sentence B is the fifth sentence: It introduces the reaction of the family members (his daughter and daughter-in-law) living in the chateau, noting that they found the situation natural.
• Sentence S2 is fixed: It concludes the paragraph by elaborating on the family members' perspective (the 'them' from sentence B), explaining why passion and suffering in love did not surprise them.
• The correct logical sequence is DACB.

Coherent paragraph after rearrangement:

'The grandfather of the owner of this hair, of whom it is the last souvenir, after many adventures, duels and elopements, at about sixty-five fell madly in love with his farmer's daughter. I knew them both. She was blond, pale, distinguished-looking, with a slow manner of talking, a quiet voice and a look so gentle that one might have taken her for a Madonna. The old nobleman took her to his home and was soon so captivated with her that he could not live without her for a min. His daughter and daughter-in-law, who lived in the chateau, found this perfectly natural, love was such a tradition in the family. Nothing in regard to a passion surprised them, and if one spoke before them of parted lovers, even of vengeance after treachery, both said in the same sad tone: 'Oh, how he must have suffered to come to that point!''

The correct answer is Option 2.

Key Points

• The paragraph describes a social interaction between a captain, a girl, and a man named Bananas.
• Sentence C follows S1: After the captain asks the question in S1, Sentence C provides the girl's immediate non-verbal reaction (smiling and shrugging).
• Sentence D follows C: This sentence provides the verbal answer to the captain's question, explaining that Bananas had taken a fancy to her and was sullen because she rejected him.
• Sentence A is the third sentence: It describes the captain's reaction to this news. Being good-humoured and not jealous, he finds the idea of Bananas being in love to be funny.
• Sentence B follows A: It provides the captain's private thought or reasoning for why Bananas had a poor chance in love, mentioning his squint.
• Finally, S2 concludes the sequence by showing the captain acting on his amusement by chaffing (teasing) Bananas during tea.
• The correct logical sequence is CDAB.

Coherent paragraph after rearrangement:

'Next day Bananas turned up again, but he was more sullen than ever, and after dinner the captain asked the girl what was the matter with him. She smiled and shrugged her pretty shoulders. She told the captain that Bananas had taken a fancy to her and he was sore because she had told him off. The captain was a good-humoured man and he was not of a jealous nature; it struck him as exceeding funny that Bananas should be in love. A man who had a squint like that had a precious poor chance. When tea came round he chaffed him gaily.'

The correct answer is reaffirmed his commitment.

Key Points

• The verb reaffirm is defined as stating or asserting something strongly once again. The prefix re- in English grammar inherently denotes repetition or a return to a previous state.
• Using the word again in conjunction with reaffirmed creates a pleonasm, which is the use of more words than are necessary to convey a meaning. This is considered a redundancy error in formal writing.
• In the original sentence, the phrase reaffirmed again essentially translates to affirmed again again, which is grammatically incorrect. Removing the word again streamlines the sentence and adheres to the rules of grammatical economy.
• The structure reaffirmed his commitment is the most precise and concise choice, maintaining the Subject-Verb-Object flow while effectively conveying that the chairman is stating his dedication a second time.

 Additional Information

• Redundant Phrases in English:
• Option 1 (reaffirmed his commitment again): Moving the word again to the end of the phrase does not eliminate the semantic overlap. It remains redundant because the re- prefix already carries the meaning of again.
• Option 2 (reiterated once again): The verb reiterate means to say something repeatedly for emphasis. Combining it with once again creates an even more wordy and redundant expression than the original sentence.
• Common examples of similar errors include return back, revert back, recede back, and repeat again. In all these cases, the adverb (back/again) should be omitted for grammatical correctness.
• Contextual Usage: In professional communication and corporate governance, using exact terminology like reaffirmed is preferred to show consistency and transparency in leadership actions.

The correct answer is 'was filled'.

Key Points

• The passage begins with the time marker 'Last month', which establishes that the entire narrative is set in the past tense.
• Supporting verbs in the context, such as 'went' and 'started', further confirm that the actions occurred in the past.
• 'Was filled' is the Simple Past Passive form, which is used to describe the state or condition of the atmosphere at that specific time.
• The other options are incorrect because:
• 'Fills' is in the Simple Present tense, used for habits or general facts.
• 'Will fill' is in the Future tense.
• 'Has filled' is in the Present Perfect tense, which implies a connection to the present.

Therefore, the correct answer is 'Option 2'.

Complete Passage: Last month, our class went on an excursion to the National Science Museum. The atmosphere 1. was filled with excitement as the bus started its journey. Our teacher reminded us to observe carefully and note important details, because the trip was meant to combine fun with learning. As we entered the museum, we saw fascinating models of satellites, robots, and ancient tools. One section 2. displayed the history of Indian inventions, from the concept of zero to modern space missions. Everyone listened attentively to the guide, who explained each exhibit with clarity. During the break, a friend said, 'Without science, progress would have been impossible.' Another replied, 'True, but blind dependence on machines 3. may lead us into laziness and health problems.' Their discussion showed how science could inspire both admiration and caution. In the afternoon, we attended a workshop on renewable energy. The instructor emphasized that innovation must go hand in hand with responsibility. His words 4. served as a reminder that every discovery has consequences, good or bad. On our way back, the teacher concluded, 'The museum visit has not just enriched your knowledge but also encouraged you to think critically. 5. Curiosity and responsibility are the pillars of education.'

Additional Information

• The Passive Voice (was/were + V3) is often used when the focus is on the state or the recipient of the action rather than the performer. In this case, the focus is on the atmosphere being characterized by excitement.

The correct answer is 'displayed'.

Key Points

• The passage is written in the past tense, as it describes an excursion that took place 'Last month'.
• The verbs used throughout the narrative, such as 'went', 'started', 'entered', and 'saw', are all in the simple past tense.
• Blank (B) requires a verb to describe what the museum section showed during the visit. To maintain tense consistency, the past tense form 'displayed' must be used.
• Other options like 'display' (present plural), 'displays' (present singular), and 'will display' (future) do not fit the chronological context of the story.

Therefore, the correct answer is 'Option 1'.

Complete Passage: Last month, our class went on an excursion to the National Science Museum. The atmosphere A. was filled with excitement as the bus started its journey. Our teacher reminded us to observe carefully and note important details, because the trip was meant to combine fun with learning.

One section B. displayed the history of Indian inventions, from the concept of zero to modern space missions. Everyone listened attentively to the guide, who explained each exhibit with clarity.

On our way back, the teacher concluded, 'The museum visit has not just enriched your knowledge but also encouraged you to think critically. E. Curiosity and responsibility are the pillars of education.'

Additional Information

• Simple Past Tense is used to describe completed actions that happened at a specific time in the past.
• Subject-Verb Agreement: Since 'One section' is a singular subject, if the sentence were in the present tense, 'displays' would be used; however, the past tense remains 'displayed' regardless of whether the subject is singular or plural (for most verbs).

The correct answer is 'may'.

Key Points

• The sentence is expressing a possibility or a potential consequence regarding the over-reliance on technology.
• The modal verb 'may' is used to indicate that something is possible, even if it is not certain. In this context, it suggests that blind dependence on machines has the potential to lead to laziness and health issues.
• 'Would' is typically used for hypothetical or conditional situations, which is less appropriate here as the speaker is talking about a realistic risk.
• 'Will' indicates certainty or a definite future outcome, which might be too absolute for a cautionary opinion.
• 'Shal' is a misspelling of 'shall' and is generally used with the first person (I/We) for suggestions or formal future statements.

Therefore, the correct answer is 'Option 3'.

Additional Information

• Possibility (May/Might/Can): Used to express that something could happen. 'May' is more formal and indicates a medium level of probability.
• Necessity/Certainty (Must/Will): Used when there is no doubt about the outcome or when something is required.
• Hypothetical (Would): Used when talking about imaginary or conditional scenarios.

The correct answer is 'served as'.

Key Points

• The passage describes an educational trip to the National Science Museum and the lessons learned by the students.
• The phrase needed in blank (D) must connect 'His words' with 'a reminder', indicating the function or role those words played.
• 'Served as' is a standard phrasal verb or collocation meaning to act as, function as, or be used as something specific.
• In this context, the instructor's words functioned as a reminder for the students, making 'served as' the most appropriate choice.

Therefore, the correct answer is 'Option 1'.

Additional Information

• Served for: Usually refers to the duration of time someone worked (e.g., He served for ten years) or a specific purpose, but it does not collocate well with 'a reminder'.
• Served over: This is not a standard idiomatic collocation in this context; it might refer to serving a period of time or serving across a distance.
• Served up: Means to present or provide something, often used for food or delivering information in a particular style (e.g., The chef served up a delicious meal).

The correct answer is 'Apathy'.

Key Points

• The word 'Curiosity' refers to a strong desire to know or learn something.
• An antonym is a word that has the opposite meaning of another word.
• 'Apathy' means a lack of interest, enthusiasm, or concern, which is the direct opposite of being curious or inquisitive.
• Therefore, 'Apathy' is the most suitable antonym for the word provided in bracket (E).

Therefore, the correct answer is 'Option 4'.
