UPPSC Prelims 2011 Question Paper with Answers & Explanations

Explanation

Zinc phosphide (Zn₃P₂) is an inorganic chemical compound widely utilized as a rodenticide for the control of rats, mice, and other pests. When a rodent ingests the bait containing zinc phosphide, the compound reacts with the hydrochloric acid present in the animal's stomach to release phosphine gas (PH₃). This phosphine gas is highly toxic, rapidly entering the bloodstream and causing systemic organ failure, particularly affecting the heart, lungs, and liver, which leads to the death of the rodent. Because of this specific chemical reaction and its high lethality to small mammals, zinc phosphide is the standard active ingredient in many commercial rat poisons.

Explanation

Carbon dioxide (CO₂) is a fundamental reactant in the photosynthesis process. Green plants and other autotrophs capture this gas from the atmosphere through specialized pores called stomata. In the presence of sunlight and chlorophyll, the carbon from CO₂ is fixed and reduced to synthesize glucose (C₆H₁₂O₆), which serves as the primary energy source for the organism. The overall chemical reaction is represented as 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂. Without the availability of carbon dioxide, the dark reaction (Calvin cycle) of photosynthesis cannot proceed, preventing the formation of organic matter and the release of oxygen as a byproduct.

Explanation

Morphine matches with Analgesic (3) because it is an opioid medication used as a potent pain reliever for severe physical distress.

Sodium matches with Kerosene oil (4) because it is a highly reactive alkali metal that reacts violently with water and air, requiring storage under an inert liquid like kerosene.

Boric Acid matches with Antiseptic (1) because it possesses mild antibacterial and antifungal properties, making it suitable for treating minor cuts or use in eyewashes.

German Silver matches with Alloy (2) because it is a solid solution of copper, zinc, and nickel, characterized by its silver-like appearance despite containing no elemental silver.

Explanation

Scurvy is a disease resulting from a deficiency of Vitamin C, or ascorbic acid, which is vital for the synthesis of collagen and the maintenance of connective tissues. Amla, also known as the Indian Gooseberry, is renowned for being one of the most concentrated natural sources of Vitamin C. Because the human body cannot synthesize Vitamin C, it must be obtained through the diet. Consuming Amla provides a high dosage of this essential nutrient, making it highly effective in both the prevention and the therapeutic treatment of scurvy symptoms such as bleeding gums, fatigue, and impaired wound healing.

Explanation

Astra is India's first indigenous Beyond Visual Range air-to-air missile, developed by the Defence Research and Development Organisation. It is designed to be integrated onto fighter aircraft like the Sukhoi-30 MKI and the Tejas Light Combat Aircraft to engage and destroy highly maneuverable supersonic aerial targets. The missile incorporates advanced guidance and navigation techniques, including mid-course inertial guidance and terminal active radar homing, allowing it to strike enemy aircraft at various ranges and altitudes under all weather conditions. Development of this missile was a significant milestone in India's missile technology, reducing dependence on imported air-to-air weapon systems.

Explanation

Golden rice is a genetically modified variety of rice developed to produce beta-carotene, a provitamin that the human body converts into Vitamin A. It was engineered by inserting genes from maize and a soil bacterium into the rice genome to complete the biosynthetic pathway for beta-carotene in the endosperm. The project was initiated to address Vitamin A deficiency (VAD) in populations that rely on rice as their primary source of calories but lack access to a diverse diet. The accumulation of beta-carotene in the grain gives the rice its distinctive golden color.

Explanation

The radiosensitivity of human organs is generally governed by the Law of Bergonie and Tribondeau, which states that cells are more susceptible to radiation damage if they have a high division rate, a long dividing future, and are least specialized. Among the given options, the eyes, specifically the ocular lens, are the most susceptible to harmful radiations.

The lens of the eye is highly radiosensitive because its epithelial cells are constantly dividing but have no mechanism to shed or remove damaged cells. When ionizing radiation strikes these cells, it causes protein denaturation and cellular damage that leads to the formation of cataracts. This damage can occur at relatively low radiation doses compared to other organs. While the lungs also contain sensitive epithelial and endothelial tissues, they have a higher threshold for damage, such as radiation pneumonitis, than the lens does for cataractogenesis. The heart and the brain are composed of highly differentiated, non-dividing cells, which makes them significantly more radioresistant to the harmful effects of ionizing radiation.

Explanation

Bharati is the third permanent research station established by India in Antarctica under the Indian Antarctic Programme. Located in the Larsemann Hills at approximately 69 degrees South latitude and 76 degrees East longitude, the station was conceptualized to facilitate advanced research in oceanography and the study of continental break-up. It follows India's previous stations, Dakshin Gangotri and Maitri, and was specifically designed to help scientists explore the geological link between the Indian subcontinent and Antarctica, which were once part of the supercontinent Gondwanaland. The station is constructed using specialized shipping containers and is engineered to withstand extreme polar conditions while maintaining a minimal environmental footprint.

Explanation

Penicillin was discovered by the Scottish scientist Alexander Fleming in 1928, a breakthrough that earned him the Nobel Prize in Physiology or Medicine in 1945. Jacob Perkins was an American inventor and physicist who is primarily credited with designing the first working vapor-compression refrigeration system in 1834. Since the discovery of the antibiotic Penicillin is historically attributed to Fleming and not Perkins, this pairing is inaccurate.

Explanation

According to the laws of reflection, for a person to see their full image in a plane mirror, light rays from the top of the head and the bottom of the feet must reflect off the mirror and enter the person's eyes. Let H be the total height of the person. If the distance from the eyes to the top of the head is h₁ and the distance from the eyes to the feet is h₂, then H = h₁ + h₂. To see the top of the head, the mirror must extend to a point halfway between the eyes and the head, covering a vertical distance of h₁/2. To see the feet, the mirror must extend to a point halfway between the eyes and the feet, covering a vertical distance of h₂/2. The minimum height of the mirror required is the sum of these two segments: h₁/2 + h₂/2 = (h₁ + h₂)/2 = H/2. This geometric relationship remains constant regardless of the person's distance from the mirror.

Explanation

Helium is a noble gas belonging to Group 18 of the periodic table, characterized by a completely filled valence shell. This electronic configuration makes it chemically inert and non-combustible under standard atmospheric conditions. Unlike hydrogen, which is highly flammable and reacts vigorously with oxygen (O₂) to form water (H₂O) in an exothermic reaction, helium does not undergo combustion or support it. Consequently, helium does not form explosive mixtures with air, making it the safer choice for use in balloons and airships where the risk of fire must be eliminated.

Explanation

Vitamin A is an essential fat-soluble nutrient that the human body cannot synthesize endogenously from basic metabolic precursors. It must be obtained through the diet either as preformed vitamin A (retinol and its esterified forms) found in animal-derived foods or as provitamin A carotenoids, such as beta-carotene, found in plants. Although the human body can convert these dietary carotenoids into active vitamin A within the liver and small intestine, it lacks the biological machinery to form the vitamin entirely on its own. This necessity for external intake is a defining characteristic of most vitamins, which are required for critical physiological functions like vision and immune health but are not produced by human cellular processes.

Explanation

Information technology terminology refers to the specialized vocabulary used in computing, telecommunications, and data management. A protocol is a fundamental set of rules or standards that define how data is transmitted and received between different devices in a network, such as the Transmission Control Protocol or Hypertext Transfer Protocol. A login is the process or the set of credentials used to authenticate a user and provide access to a computer system or digital network. Since both terms are essential concepts in the operation and communication of modern computing systems, they are both considered core components of IT terminology.

Explanation

Sir Tim Berners-Lee invented the World Wide Web in 1989 while working as a software engineer at CERN, the particle physics laboratory in Switzerland. He developed the fundamental technologies that remain the basis of the modern web, including Hypertext Markup Language (HTML), Hypertext Transfer Protocol (HTTP), and Uniform Resource Locators (URLs). In 1990, he wrote the first web browser and established the first web server. To ensure the web remained an open and global platform, he founded the World Wide Web Consortium (W3C) in 1994 at the Massachusetts Institute of Technology to develop interoperable technologies and standards. He is widely recognized for his decision to make the source code of the web available for free, allowing for its rapid global expansion.

Explanation

Assertion (A) is false because green vegetables are not the exclusive source of Vitamin A. A person can maintain healthy levels of this vitamin by consuming other rich sources such as carrots, sweet potatoes, pumpkins, milk, eggs, and liver. Therefore, stopping the intake of green vegetables does not automatically result in night blindness. Reason (R) is true because night blindness is a clinical manifestation of Vitamin A deficiency. This deficiency impairs the production of rhodopsin, a light-sensitive pigment in the retina that is essential for vision in low-light or dim conditions.

Explanation

Anosmia is a medical condition characterized by the complete loss of the ability to detect odors. This sensory deficit occurs when there is an interruption in the olfactory pathway, which may be caused by physical blockages in the nasal cavity, inflammation of the nasal mucosa, or damage to the olfactory nerves and the brain regions responsible for processing scents. It is distinct from hyposmia, which is a reduced ability to smell, and can significantly impact the perception of flavor, as smell plays a critical role in the sensory experience of food. Common triggers for the condition include upper respiratory infections, head trauma, and chronic sinonasal disease.

Explanation

The retina is the light-sensitive innermost layer of the eye where the lens focuses images. It contains photoreceptor cells, such as rods and cones, which detect light and convert it into neural signals. In a traditional camera, the film acts as the recording medium and is coated with light-sensitive chemicals. Much like the retina, the film is positioned at the back of the device where the image is projected and captured. Both the retina and the film serve the identical functional role of being the surface upon which a focused optical image is received and recorded for further processing.

Explanation

AIDS (Acquired Immunodeficiency Syndrome) is caused by the Human Immunodeficiency Virus (HIV), which is a member of the lentivirus genus within the retrovirus family. This virus infects vital cells in the human immune system, such as helper T cells (specifically CD4+ T cells), macrophages, and dendritic cells. By integrating its genetic material into the host cell's DNA, the virus replicates and systematically destroys these immune cells. The resulting severe loss of immune function makes the individual highly susceptible to life-threatening infections and malignancies. HIV is primarily transmitted through the exchange of bodily fluids during unprotected sexual contact, contaminated blood transfusions, or from mother to child during pregnancy, childbirth, or breastfeeding.

Explanation

Gambusia affinis, commonly known as the mosquitofish, is a freshwater fish widely utilized globally as a biological control agent against mosquitoes. It is particularly effective because it is a surface feeder that predominantly preys on mosquito larvae and pupae. By consuming these larvae before they can mature into adult insects, Gambusia helps significantly reduce the transmission of mosquito-borne diseases such as malaria and dengue. Its high reproductive capacity, resilience in diverse aquatic environments, and specialized diet make it a primary tool in integrated pest management programs aimed at controlling mosquito populations without the use of chemical insecticides.

Explanation

The regulation of blood sugar levels is primarily the responsibility of the pancreas, which secretes hormones such as insulin and glucagon. Insulin helps lower blood glucose levels by facilitating the uptake of glucose into cells, while glucagon raises blood glucose by stimulating the liver to convert stored glycogen into glucose. While the kidneys are involved in filtering glucose from the blood and reabsorbing it back into the systemic circulation through the proximal convoluted tubules, they do not possess the sensory or endocrine mechanisms required to regulate and maintain homeostatic blood sugar concentrations. The appearance of glucose in urine typically occurs only when blood sugar levels exceed the renal threshold, which is a symptom of a metabolic issue rather than a normal regulatory function of the kidney.

Explanation

Thrombin is an essential serine protease enzyme that facilitates the blood clotting process by converting soluble fibrinogen into insoluble fibrin strands. This conversion is the final step in the coagulation cascade, where the resulting fibrin network traps platelets and blood cells to form a stable clot at the site of vascular injury. Thrombin is generated from its inactive precursor, prothrombin, through the action of the prothrombinase complex. In addition to its role in fibrin formation, thrombin further promotes hemostasis by activating other clotting factors and stimulating platelet aggregation, ensuring the integrity of the circulatory system after tissue damage.

Explanation

Indane is a brand of Liquefied Petroleum Gas (LPG) marketed by the Indian Oil Corporation. LPG is a flammable mixture of hydrocarbon gases, primarily consisting of propane and butane. These alkanes are extracted during the refining of petroleum or from natural gas streams. In India, domestic LPG cylinders contain a pressurized mixture of these two gases in liquid form, which vaporizes upon release. While the exact ratio can vary based on regional standards and seasonal temperatures, the combination of butane and propane provides the necessary vapor pressure and energy density required for efficient household cooking.

Explanation

Bone Mineral Density (BMD) testing is a medical procedure used to measure the level of minerals, primarily calcium, within a specific volume of bone. It is the gold standard for diagnosing osteoporosis, a condition characterized by a decrease in bone mass and density that leads to increased bone fragility and risk of fractures. The most common method for measuring BMD is Dual-Energy X-ray Absorptiometry (DEXA or DXA) scan. The results are typically reported as a T-score, which compares the patient's bone density to that of a healthy young adult. According to the World Health Organization, a T-score of -2.5 or lower indicates the presence of osteoporosis, while scores between -1 and -2.5 indicate osteopenia.

Explanation

Amniocentesis is a prenatal diagnostic procedure performed during pregnancy to detect chromosomal abnormalities and genetic defects in the fetus. The process involves using a needle to withdraw a small sample of amniotic fluid from the amniotic sac surrounding the developing fetus. This fluid contains live fetal cells, such as those shed from the skin and respiratory tract, which carry the genetic information of the unborn child. By culturing these cells and performing a chromosomal analysis known as karyotyping, medical professionals can examine the complete set of chromosomes. Because this analysis identifies the sex chromosomes, XX for a female and XY for a male, amniocentesis serves as a definitive method to determine the foetal sex. While its primary medical purpose is to screen for conditions like Down syndrome or spina bifida, its ability to reveal the sex of the fetus is a direct application of the cellular analysis involved.

Explanation

Graphite is used as a moderator in nuclear reactors to slow down fast neutrons produced during the fission process. For a nuclear chain reaction to be sustained efficiently, neutrons must be decelerated to thermal energy levels, as slower neutrons have a significantly higher probability of being captured by U-235 nuclei to induce further fission.

A good moderator must have a low atomic mass to facilitate energy transfer through elastic collisions and a very low neutron absorption cross-section to ensure that neutrons are slowed down rather than being lost. Graphite, a crystalline form of carbon, fulfills these requirements effectively. Its high purity and structural stability at high temperatures allow it to maintain a consistent neutron flux within the reactor core. This property historically allowed for the development of reactors that could achieve criticality using natural uranium fuel.

Explanation

Subrahmanyan Chandrasekhar established the theoretical foundation for the final stages of stellar evolution by defining the Chandrasekhar Limit. This limit, which is approximately 1.44 times the mass of the Sun (M_☉), represents the maximum mass a white dwarf star can possess while remaining stable against gravitational collapse. He demonstrated that stars exceeding this mass threshold would continue to contract under their own gravity, eventually leading to the formation of neutron stars or black holes. His work provided the mathematical proof necessary to understand the lifecycle of massive stars and the inevitability of gravitational singularities, for which he was awarded the Nobel Prize in Physics in 1983.

Explanation

Refrigeration works by lowering the temperature of food, which significantly slows down the kinetic energy of molecules involved in chemical and biological processes. The rate of these biochemical reactions, including microbial growth and enzymatic activity that lead to spoilage, is governed by the Arrhenius equation k = Ae⁻ᴱᵃ/ᴿᵀ. In this equation, k represents the reaction rate constant and T is the absolute temperature. As the temperature T decreases, the value of k decreases exponentially, meaning the chemical transformations responsible for food decay proceed at a much slower pace. By maintaining a cold environment, refrigeration inhibits the metabolic functions of bacteria and fungi and reduces the speed of internal enzymatic reactions, thereby extending the shelf life of the food.

Explanation

Convex mirrors are used as rear-view mirrors in vehicles because they always form an erect and virtual image of the objects behind the vehicle. These mirrors are curved outwards, which provides a significantly wider field of view compared to other mirror types. This allows the driver to monitor a much larger area of traffic than would be possible with a flat surface. While the images produced are diminished in size, the broad perspective of the road provided by the convex shape is essential for safety, lane changing, and awareness of approaching vehicles.

Explanation

Tungsten is the standard material for electric bulb filaments because it possesses the highest melting point of any metal in its pure form, reaching approximately 3422°C. This property allows the filament to reach the high temperatures necessary for incandescence—producing visible light—without melting. Furthermore, tungsten has a high electrical resistivity, which enables it to generate significant heat as current passes through it, and a very low vapor pressure at high temperatures, which prevents the filament from evaporating quickly and darkening the bulb's interior surface.

Explanation

Ajatasatru was a king of the Haryanka dynasty of Magadha who ruled in the early 5th century BCE. According to Buddhist traditions recorded in texts like the Mahavamsa, he imprisoned his father, King Bimbisara, to seize the throne. Driven by his ambition and influenced by Devadatta, Ajatasatru eventually caused his father's death in prison, typically cited as starvation. This act of parricide is a well-documented event in ancient Indian history, earning him a reputation for ruthlessness during his rise to power. His reign subsequently saw the expansion of the Magadhan empire through the annexation of territories like Vaishali and Kashi.

Explanation

Gautam Buddha attained Mahaparinirvana at the age of 80 in Kushinagar. During the 6th century BCE, Kushinagar served as the capital of the Malla Mahajanapada, which was one of the prominent ancient Indian republics. After traveling from Pava and falling ill, the Buddha reached a grove of Sal trees belonging to the Mallas near the Hiranyavati River. It was at this location that he delivered his final instructions to his disciples and passed into the state of final liberation. The Malla clan took responsibility for his funeral rites and the initial preservation of his relics.

Explanation

Gautama Buddha spent the largest part of his monastic life in Sravasti, which was the capital of the Kosala kingdom. Records indicate that he observed twenty-five rainy season retreats (Varshavas) in Sravasti, staying nineteen seasons at the Jetavana monastery and six seasons at the Purvarama monastery. Because he resided there longer than any other location, he delivered the maximum number of his sermons and discourses in this city. A vast majority of the teachings recorded in the Pali Canon are attributed to the period the Buddha spent preaching to the large community of monks and lay followers established in Sravasti.

Explanation

Chandragupta I, who reigned from approximately 319 to 335 CE, was the first ruler of the Gupta dynasty to issue gold coins. These coins are famously known as the Chandragupta-Kumaradevi type, featuring portraits of the king and his queen, who was a Lichchhavi princess, on the obverse. The introduction of this coinage coincided with his assumption of the imperial title Maharajadhiraja, which established the sovereign status of the Gupta Empire. The issuance of these gold coins served as a symbol of the dynasty's rising political authority and economic prosperity during his reign, distinguishing him as the pioneer of Gupta numismatics.

Explanation

Patanjali, the great grammarian and author of the Mahabhasya, flourished during the 2nd century BCE and was a contemporary of the Sunga king Pushyamitra Sunga. Internal evidence within the Mahabhasya provides direct historical links to this period, most notably through Patanjali’s mention of conducting a horse sacrifice (Ashvamedha) for Pushyamitra Sunga. He uses the present tense in the phrase iha pushyamitram yajayamah to signify his personal participation in the ritual. Additionally, Patanjali refers to the Greek or Yavana incursions into Indian territories like Saketa and Madhyamika, events which are historically recorded as having taken place during the reign of the first Sunga monarch. This textual evidence firmly establishes his chronological placement within the Sunga era.

Explanation

The Vikram Samvat era was established in 58 BC, traditionally attributed to King Vikramaditya of Ujjain to commemorate his victory over the Sakas. The Saka Samvat began in 78 AD and is widely believed to have been started by the Kushan emperor Kanishka upon his accession to the throne; it currently serves as the basis for the Indian National Calendar. The Gupta era commenced in 319 AD, marking the coronation of Chandragupta I, which signaled the rise of the Gupta Empire in northern India. The fourth statement is historically inaccurate as the establishment of Muslim rule in India is generally dated to 1192 AD following the Second Battle of Tarain, whereas 192 AD predates the birth of Prophet Muhammad and the emergence of Islam.

Explanation

Sheikh Moinuddin Chisti, popularly known as Khwaja Gharib Nawaz, was the first major Sufi saint of the Chisti Silsila to establish a permanent base in India. He arrived in the Indian subcontinent from Sistan via Lahore and Delhi in the late 12th century, eventually settling in Ajmer during the reign of Prithviraj Chauhan. His arrival marked the beginning of the Chisti order's influence in the region. He transformed Ajmer into a significant center for spiritual and social activities, where he lived until his death in 1236 CE. His presence in Ajmer predates the establishment of other major Chisti centers in Delhi or elsewhere by his successors and disciples.

Explanation

Firoz Shah Tughlaq was the first Sultan of Delhi to impose Jaziya on Brahmins, who had previously been exempted from this tax under earlier rulers. His reign was marked by a strict adherence to Sharia and the influence of the Ulema in state affairs. He viewed the exemption of Brahmins as a violation of religious law and argued that as they were the leaders of the non-Muslim community, they must also pay the tax. Despite widespread protests and hunger strikes by Brahmins in Delhi, the Sultan refused to withdraw the order, eventually forcing the community to comply, although the tax was collected at a lower rate for them.

Explanation

Tipu Sultan, the ruler of Mysore, was a pioneer in recognizing the significance of international diplomacy to counter British expansion in India. He established embassies in various foreign countries on modern lines, sending diplomatic missions to the Ottoman Empire (Istanbul) in 1787 and to France (Versailles) in 1788. These missions sought military and commercial alliances, with the embassy to France specifically aiming for a treaty with Louis XVI. He also maintained diplomatic correspondence with Napoleon Bonaparte, the Sultan of Oman, and the Zamaun Shah of Afghanistan. By adopting formal diplomatic protocols, including the exchange of credentials and specific negotiating mandates, Tipu Sultan attempted to internationalize the conflict against the British East India Company and modernize Mysore's external relations.

Explanation

Maize is a New World crop native to Central America and was introduced to the Indian subcontinent by the Portuguese explorers and traders. This introduction occurred only after the end of the 15th century, following Vasco da Gama's arrival in Calicut in 1498. Since the 13th and 14th centuries fall within the Delhi Sultanate period and predate European maritime contact with the Americas, maize was not available for cultivation by Indian peasants during that time. It became a significant part of Indian agriculture only during the Mughal period in the 16th and 17th centuries.

Explanation

Sikandar Lodhi founded the city of Agra in 1504. He established the settlement to serve as a strategic military base and administrative center, allowing him to exercise better control over the rebellious chiefs of the Doab region and to monitor the routes leading to Gwalior and Malwa. In 1506, he officially shifted the capital of the Delhi Sultanate from Delhi to Agra. Under his patronage, the city began its transformation into a significant political and cultural center, a status that was further elevated later during the Mughal era.

Explanation

Raja Jai Singh I of Amber was a high-ranking Mughal general appointed by Emperor Aurangzeb to lead a massive campaign against Chhatrapati Shivaji Maharaj in the Deccan. After Jai Singh successfully besieged the strategic fort of Purandhar and applied intense military pressure, Shivaji realized the necessity of a diplomatic settlement to prevent further destruction. The Treaty of Purandhar was signed on June 11, 1665, between Jai Singh, representing the Mughal Empire, and Shivaji. According to the terms, Shivaji ceded twenty-three forts to the Mughals while retaining twelve for himself, agreed to provide military support for the Mughal invasion of Bijapur, and consented to send his son Sambhaji to the Mughal court as a mansabdar. Jai Singh's strategic victory and subsequent negotiations were pivotal in briefly bringing the Maratha ruler into the Mughal administrative fold.

Explanation

Vinayak Damodar Savarkar, along with his brother Ganesh Savarkar, started the Mitra Mela in 1899 at Nashik. It was a secret revolutionary organization founded to advocate for the absolute political independence of India from British rule. The association focused on physical training, the promotion of Swadeshi goods, and the dissemination of nationalistic ideas through literature and patriotic songs. In 1904, during a gathering of several hundred revolutionaries, the Mitra Mela was expanded and renamed the Abhinav Bharat Society, taking inspiration from Giuseppe Mazzini's Young Italy. This organization became one of the most influential secret societies in Western India, coordinating various revolutionary activities against the colonial administration.

Explanation

At the annual session of the Indian National Congress held in Nagpur in December 1920, Chittaranjan Das (C.R. Das) moved the main resolution on the Non-Cooperation Movement. Although he had initially opposed certain aspects of the program during the special Calcutta session in September 1920, he reached a compromise with Mahatma Gandhi before the Nagpur meet. The session, presided over by C. Vijayaraghavachariar, ratified the Non-Cooperation program and marked a pivotal shift in the Congress's creed toward the attainment of Swaraj through peaceful and legitimate means. C.R. Das's role in moving the resolution signaled the unification of the Congress leadership behind Gandhi's mass movement strategy.

Explanation

Jawaharlal Nehru made this famous declaration during his presidential address at the Lucknow Session of the Indian National Congress in April 1936. In this landmark speech, Nehru explicitly identified himself as a socialist and a republican, emphasizing that the only key to the solution of India's problems lay in socialism. His statement reflected a clear ideological stance against the feudal nature of the Princely States and the institution of monarchy, advocating for a democratic and egalitarian future for independent India. Under his influence during this period, the Congress party began to integrate more socialist principles into its national agenda.

Explanation

The correct chronological order is: (1) August Offer, 1940 by Viceroy Linlithgow offering dominion status post-war; (3) Cripps Mission, 1942 to secure Indian cooperation during WWII; (4) Wavell Plan/Shimla Conference, 1945 to form an executive council; (2) Cabinet Mission, 1946 to plan transfer of power. The sequence 1, 3, 4, 2 corresponds to Option B.

Explanation

Syed Haider Raza was a prominent nationalist leader who organized and spearheaded the Swadeshi Movement in Delhi. After the partition of Bengal in 1905, the movement transitioned from a regional protest to a national struggle. Raza was instrumental in mobilizing public opinion in the Delhi region by organizing meetings and promoting the boycott of foreign goods while encouraging the use of indigenous products. His leadership ensured that the anti-partition agitation gained significant momentum in the capital, aligning with the efforts of other extremist leaders who sought to spread the movement across India.

Explanation

Jai Prakash Narayan was a prominent socialist leader who played a pivotal role in the underground phase of the Quit India Movement. Following the mass arrests of the Congress leadership in August 1942, he was imprisoned in the Hazaribagh Central Jail in Bihar. On the night of Diwali in November 1942, he made a daring escape from the prison along with five other inmates. After his escape, he crossed over into the Terai region of Nepal, where he organized the Azad Dasta, an underground guerilla force. This organization was designed to train volunteers in sabotage techniques, such as disrupting railway lines and telegraph wires, to paralyze the British administration. His efforts were instrumental in sustaining the momentum of the movement through secret channels when open protests were being suppressed by the colonial authorities.

Explanation

Tatya Tope was one of the most prominent military leaders of the Indian Rebellion of 1857. Born in 1814 in Yeola, Maharashtra, his birth name was Ram Chandra Pandurang Yawalkar. He was a close associate and loyal commander of Nana Saheb. He played a significant role in the siege of Kanpur and later led the rebel forces in Gwalior alongside Rani Lakshmibai. Tatya Tope is specifically remembered for his mastery of guerrilla warfare, which allowed him to evade and harass British forces across Central India for a prolonged period. He was eventually captured due to the betrayal of a local chieftain and was executed by the British at Shivpuri in April 1859.

Explanation

Mahatma Gandhi presided over the Indian National Congress session only once in his life, which was the 39th annual session held at Belgaum in December 1924. This session is historically significant as it marked Gandhi's return to active politics after his release from prison earlier that year. During this session, he worked to bridge the rift between the Swarajists and the No-changers, ultimately reaching a compromise that allowed the Swaraj Party to work within the legislative councils while remaining part of the Congress. Gandhi used his presidency to emphasize his constructive program, focusing on the promotion of Khadi, the removal of untouchability, and the necessity of Hindu-Muslim unity as essential requirements for achieving Swaraj. This remains the only instance where he served as the formal president of the organization.

Explanation

Dr. B.R. Ambedkar was one of the few Indian leaders who participated in all three Round Table Conferences held in London between 1930 and 1932. Representing the Depressed Classes, he utilized these forums to demand political safeguards and separate electorates for the marginalized sections of Indian society. His involvement in the first session in 1930, the second session in 1931, and the third session in 1932 focused on securing legal and constitutional rights to ensure social and political equality in a future independent India. His persistent advocacy during these conferences played a crucial role in the announcement of the Communal Award and the negotiations that led to the Poona Pact. Alongside Ambedkar, Sir Tej Bahadur Sapru was another prominent figure who attended all three sessions.

Explanation

Surendranath Banerjee was the primary leader of the agitation against the Partition of Bengal announced by Lord Curzon in 1905. Known as the Indian Burke, he spearheaded the Swadeshi and Boycott movements through the Indian Association and his newspaper, The Bengalee. He presided over the historic meeting at the Calcutta Town Hall on August 7, 1905, where the Boycott resolution was formally adopted to protest the division of the province. His role in mobilizing public opinion and organizing mass protests across Bengal was instrumental in the early phase of the anti-partition struggle, which eventually led to the annulment of the partition in 1911.

Explanation

Mahatma Gandhi returned to India from South Africa in January 1915 and initially spent time traveling across the country to understand its social and political landscape. In 1917, at the request of Rajkumar Shukla, he visited the Champaran district in Bihar to address the plight of peasants forced by European planters to cultivate indigo under the oppressive Tinkathia system. This system required farmers to grow indigo on 3/20th of their land, often at a loss. Gandhi utilized the principles of Satyagraha for the first time in India to protest this exploitation. The movement forced the government to appoint an inquiry committee, which included Gandhi as a member, leading to the abolition of the Tinkathia system and a partial refund of illegally collected dues to the peasants.

Explanation

Chandra Shekhar Azad was a key member of the Hindustan Republican Association (HRA) and a central figure in the Kakori train robbery of 1925. Following the event, while the British authorities conducted widespread raids and arrested most of the participants, Azad managed to escape the police dragnet and remained a fugitive. He was declared an absconder in the subsequent Kakori Conspiracy Case trial. While several of his fellow revolutionaries were captured, sentenced to death, and executed in 1927, Azad continued his underground activities and reorganized the HRA into the Hindustan Socialist Republican Association (HSRA). He was never apprehended or hanged by the British judicial system, eventually dying in a self-inflicted gunshot during a police encounter at Alfred Park, Allahabad, in February 1931.

Explanation

Uttarakhand became the first state in India to grant Sanskrit the status of its second official language in January 2010. This was achieved through the Uttarakhand Official Language (Amendment) Bill, which was passed under the administration of Chief Minister Ramesh Pokhriyal Nishank. The decision was motivated by the state's deep cultural and religious roots, often referred to as Devbhoomi or the Land of the Gods, and aimed to promote the study and use of the ancient language in official capacities and educational institutions. This status allows for the use of Sanskrit in signboards, official ceremonies, and certain administrative documentations alongside Hindi, which is the primary official language.

Explanation

Article 169 of the Constitution of India provides the legal mechanism for the abolition or creation of Legislative Councils in the states. Under this provision, the Parliament of India has the authority to create or abolish the upper house of a state legislature if the Legislative Assembly of that state passes a resolution requesting such a change. This resolution must be passed by a special majority, which is defined as a majority of the total membership of the Assembly and a majority of not less than two-thirds of the members of the Assembly present and voting. Following the state's resolution, the Parliament may then enact a law to give effect to the creation or abolition of the Council. Crucially, any such law passed by Parliament for this purpose is not considered an amendment to the Constitution for the purposes of Article 368.

Explanation

Under Article 88 of the Constitution of India, the Attorney General of India has the right to speak in, and otherwise to take part in the proceedings of, either House of Parliament, any joint sitting of the Houses, and any committee of Parliament of which he may be named a member. As the highest law officer in the country appointed under Article 76, the Attorney General is granted this special privilege to provide legal counsel and represent the executive's perspective during legislative deliberations. While the Attorney General enjoys all the privileges and immunities available to a Member of Parliament, this right to participate in proceedings specifically excludes the right to vote.

Explanation

The voting age in India was lowered from 21 years to 18 years through the 61st Constitutional Amendment Act of 1988, which amended Article 326 of the Constitution. This legislative change received presidential assent and came into force on March 28, 1989. As a result, the 1989 General Elections for the 9th Lok Sabha became the first national elections in which the newly eligible youth population aged 18 to 20 could exercise their right to vote. The amendment aimed to increase the involvement of the younger generation in the country's political process.

Explanation

According to Article 75 and Article 88 of the Indian Constitution, Ministers can be members of either the Lok Sabha or the Rajya Sabha. There is no constitutional requirement or restriction that limits membership of the Cabinet specifically to the Lower House. A Minister has the right to speak and take part in the proceedings of either House or any committee of Parliament of which they may be named a member, regardless of which House they belong to. Furthermore, Article 75(5) allows a person who is not a member of either House to be appointed as a Minister for a maximum period of six months, after which they must be elected to either the Lok Sabha or the Rajya Sabha to continue in office. Numerous Prime Ministers and Cabinet Ministers in India have historically been members of the Upper House.

Explanation

According to the India Human Development Report 2011, Kerala ranked first among Indian states with a Human Development Index value of 0.790, driven by its high literacy rates, low infant mortality, and high life expectancy. At the same time, data from the National Sample Survey Organisation (NSSO) 66th round and the Labour Bureau's 2010-11 report showed that Kerala had the highest unemployment rate in the country, largely due to a mismatch between the high educational attainment of its workforce and the availability of suitable local jobs. While both statements are factually accurate, the high unemployment rate does not explain or cause the high human development index; rather, the high HDI is a result of long-term investments in social sectors like education and health.

Explanation

An LIC policy is unique because it is a participating instrument that allows the holder to share in the profits of the institution. Under the Life Insurance Corporation Act of 1956, the corporation is legally required to distribute 95% of its surplus (profit) to its policyholders in the form of bonuses. This profit-sharing mechanism grants the policyholder a quasi-ownership interest in the financial surplus of the corporation. In contrast, bank deposits, government savings certificates like Kisan Vikas Patra, and debentures are debt instruments where the investor acts strictly as a creditor. In those cases, the investor is entitled only to a fixed or predetermined interest payment and has no legal claim on the underlying profits or ownership of the issuing entity.

Explanation

The National Highways Authority of India (NHAI) derives its primary funding from the Central Road Fund (CRF), which was established by the Central Road Fund Act, 2000. This fund is sustained through a dedicated cess levied on the sale of petrol and high-speed diesel across the country. The revenue generated from this cess is specifically earmarked for the development and maintenance of the national highway network. This reliable and consistent flow of capital serves as the backbone for the National Highways Development Project (NHDP), allowing NHAI to execute large-scale infrastructure projects and leverage these funds to secure additional financing from other sources.

Explanation

ECGC (Export Credit Guarantee Corporation) promotes foreign trade by providing export credit insurance to Indian exporters against the risk of non-payment by foreign buyers, which encourages banks to provide more liberal credit facilities for international transactions. MMTC (Metals and Minerals Trading Corporation) is a premier international trading house that handles the export and import of high-volume commodities such as minerals, metals, and fertilizers, playing a central role in India's bulk trade operations. STC (State Trading Corporation) was established to manage and stimulate trade, particularly with state-trading nations, and deals in a diverse range of agricultural and industrial products to expand India's presence in global markets. These organizations collectively provide the financial security, logistical framework, and marketing expertise necessary to facilitate and grow the nation's external commerce.

Explanation

A Letter of Credit is a financial instrument used in international trade that acts as a guarantee from a bank that a seller will receive a buyer's payment in full and on time. The process is initiated by the importer, who requests their bank to issue the letter in favor of the exporter. By producing this document, the importer provides the exporter with security, as the bank assumes the obligation to pay once the terms of the credit, such as the shipment of goods and presentation of required documents, are met. This mechanism effectively transfers the credit risk from the importer to the issuing bank.

Explanation

The import procedure formally commences with the placement of an Indent. An indent is a comprehensive purchase order sent by an importer to an overseas supplier or an agent, detailing the specific requirements of the goods to be purchased. It includes essential information such as the description, quality, quantity, and price of the goods, as well as instructions regarding packing, shipping, and insurance. By issuing this document, the importer officially initiates the transaction, providing the exporter with the necessary authorization and specifications to prepare the shipment. This step typically occurs after the importer has obtained the necessary import licenses and secured a line of credit or foreign exchange.

Explanation

The Reserve Bank of India (RBI) is the statutory body and the central authority responsible for the management of foreign exchange in India under the Foreign Exchange Management Act (FEMA), 1999. As the custodian of the country's foreign exchange reserves, the RBI regulates all transactions involving foreign currency to maintain the stability of the Indian Rupee and ensure the smooth flow of external trade. The RBI issues licenses to Authorised Dealers, such as commercial banks, to carry out foreign exchange transactions, but these entities must operate within the framework and limits prescribed by the central bank. Consequently, the RBI holds the ultimate power to sanction and control the allocation of foreign exchange for the purpose of importing goods into the country.

Explanation

The Indian mutual fund industry was opened to the private sector in 1993, marking a significant shift from the previous era dominated by public sector entities. This change was formalized with the introduction of the SEBI (Mutual Fund) Regulations, 1993, which provided a comprehensive regulatory framework for the operation of these funds. Kothari Pioneer, which later merged with Franklin Templeton, became the first private sector mutual fund to be registered in India in July 1993. This policy reform aimed to foster competition, enhance transparency, and provide a wider range of investment products to the public by allowing private asset management companies to operate in the domestic market.

Explanation

In the Union Budget 2011-2012, the Government of India provided short-term crop loans to farmers at an interest rate of 7 percent per annum through the Interest Subvention Scheme. To incentivize disciplined borrowing and timely repayment, the Finance Minister increased the additional interest subvention for farmers who repay their loans on or before the due date from 2 percent to 3 percent. Subtracting this 3 percent prompt repayment incentive from the base interest rate of 7 percent results in an effective interest rate of 4 percent for such farmers.

Explanation

MODVAT, which stands for Modified Value Added Tax, was introduced in the 1986-87 Union Budget to implement the principles of Value Added Tax within the existing central excise structure. It is a system that allows manufacturers to claim credit for the taxes paid on inputs and raw materials used in the production of goods. This mechanism ensures that the tax is ultimately levied only on the value added at each stage of the manufacturing process, effectively eliminating the cascading effect where tax is calculated on the tax already paid at earlier stages. By shifting the tax base to value addition, MODVAT streamlined the indirect tax system and served as the precursor to the CENVAT and the later Goods and Services Tax regimes.

Explanation

Tata Consultancy Services (TCS) was the largest Indian software company in 2011 based on total revenue, profitability, and market capitalization. During the fiscal year 2010-11, TCS achieved a significant milestone by becoming the first Indian IT services company to exceed 8 billion dollars in annual revenue. The company consistently held the top position in the annual industry rankings released by NASSCOM, which evaluated firms based on their export and domestic turnover. By March 2011, TCS had expanded its global workforce to over 200,000 employees, reinforcing its scale and dominant market share within the global information technology and consulting landscape. This period marked a phase of high growth where TCS maintained a substantial lead in financial performance and valuation over its domestic competitors.

Explanation

Maharashtra was the leading producer of sugar in India during the 2010-11 crushing season. The state dominance in the sugar industry is primarily due to the high concentration of cooperative sugar mills and the favorable agro-climatic conditions of the Deccan plateau. The tropical climate in Maharashtra allows for a longer crushing period and yields sugarcane with a higher sucrose content compared to the subtropical regions of North India. During the 2010-11 period, Maharashtra sugar output exceeded other states by producing approximately 9.05 million tonnes of sugar, which accounted for a substantial portion of the national total. The efficient cooperative model and better recovery rates from the cane varieties grown in the peninsular region were key factors in maintaining this top position.

Explanation

The Zaid season is a short cropping season that occurs between the harvesting of Rabi crops and the sowing of Kharif crops, typically from March to June. During this period, farmers in regions with reliable irrigation facilities utilize the summer heat to grow quick-maturing crops. Moong and Urad are short-duration pulses that fit perfectly into this window, often requiring only 60 to 70 days to reach maturity. These crops are particularly valued during Zaid because they are drought-tolerant but thrive with controlled irrigation, and their ability to fix atmospheric nitrogen helps in maintaining soil health for the subsequent Kharif season. In the irrigated tracts of the Indo-Gangetic plains, these pulses provide an essential supplementary income and protein source during the summer months.

Explanation

Kuwait is recognized as one of the most urbanized countries globally and the most urbanized in West Asia, with an urban population rate reaching approximately 98 percent by 2011. The nation operates largely as a city-state where the population is concentrated within the Kuwait City metropolitan area. This extreme level of urbanization is a result of its geographic constraints, such as its small land area and harsh desert environment, coupled with a high-income economy focused on petroleum and trade that centralizes labor and infrastructure in urban centers.

Explanation

According to the provisional figures of the 2011 Census, Lakshadweep is the least populated administrative unit in India, with a total population of approximately 64,473. In terms of population density, Arunachal Pradesh recorded the lowest figure in the country, with only 17 persons per square kilometer. Regarding population growth, Dadra and Nagar Haveli registered the highest decadal growth rate of 55.88 percent between 2001 and 2011. These demographic indicators confirm the validity of statements 1, 3, and 4.

Explanation

According to the India State of Forest Report (ISFR) 2011, the term Forest Area refers to the Recorded Forest Area (RFA), which represents land legally classified as forest in government records. The RFA values for the given states as per the 2011 report (which used data from ISFR 2009 and 2011) are as follows:

Andhra Pradesh: 63,814 km² Maharashtra: 61,939 km² Orissa: 58,136 km² Arunachal Pradesh: 51,540 km²

Arranging these states in descending order of their Recorded Forest Area yields the sequence Andhra Pradesh (1) > Maharashtra (3) > Orissa (4) > Arunachal Pradesh (2). This corresponds to the code 1, 3, 4, 2. Unlike Forest Cover, which measures actual tree canopy, Recorded Forest Area is based on administrative and legal boundaries where Andhra Pradesh and Maharashtra had larger designated tracts than Arunachal Pradesh during this period.

Explanation

According to the India State of Forest Report 2011, Arunachal Pradesh has the largest area under the very dense forest category in India. The Forest Survey of India defines very dense forest as all lands with a tree canopy density of 70 percent and above. In the 2011 assessment, Arunachal Pradesh reported approximately 20,868 square kilometers of very dense forest, a figure that far exceeds the coverage in other states. This vast expanse of high-density canopy is largely due to the state's location in the Eastern Himalayas, characterized by high rainfall and a topography that limits human interference in primary forest zones.

Explanation

Bihar registered the highest percentage point increase in literacy rate during the 2001-2011 decade according to the Census 2011 data. The state literacy rate jumped from 47.00 percent in 2001 to 61.80 percent in 2011, indicating an absolute increase of 14.80 percentage points. This growth was the most significant improvement recorded by any state in India during this period, driven largely by a substantial rise in female literacy which increased from 33.12 percent in 2001 to 51.50 percent in 2011.

Explanation

Based on the demographic data from the Census of India 2001 and the provisional figures available around 2011, Delhi reported the largest absolute slum population among the given cities. According to the 2001 Census, Delhi's slum population was approximately 1.85 million people. The city serves as a major destination for interstate migration, which led to the expansion of numerous notified and non-notified slum clusters. While Mumbai holds the highest slum population in India, Delhi consistently maintained a higher volume of slum dwellers compared to other metropolitan centers like Chennai, Bangalore, and Surat, reflecting the intense urban density and housing challenges in the national capital region.

Explanation

Based on the provisional data of the 2011 Census, Allahabad (now Prayagraj) was the most populous district in Uttar Pradesh with a population of approximately 59.54 lakh. Ghaziabad followed as the next most populous among the given districts with about 46.81 lakh people. Azamgarh recorded a population of roughly 46.13 lakh, while Lucknow, the state capital, had a population of approximately 45.89 lakh. Consequently, the descending order of these districts by population size is Allahabad (1), Ghaziabad (3), Azamgarh (2), and Lucknow (4).

Explanation

The 2011 Census provisional figures identified Daman and Diu as having the lowest sex ratio in the country at 618 females per 1000 males. This demographic indicator highlights a stark gender imbalance in the Union Territory, primarily attributed to the high influx of male migrants working in the local industrial sectors. The sex ratio is defined as the number of females per 1000 males in the population, and the figure of 618 was the minimum value recorded among all administrative divisions in India during the 2011 enumeration.

Explanation

According to the provisional figures released for the 2011 Census of India, Maharashtra is the second most populous state in the country. The state recorded a total population of approximately 11,23,74,333, which accounts for about 9.28 percent of India total population. While Uttar Pradesh holds the first rank in terms of population, Maharashtra follows as the second, maintaining its significant demographic position. The 2011 data indicated a decadal growth rate of approximately 15.99 percent for the state compared to the 2001 census findings.

Explanation

China has been the leading producer of crude steel in the world since the mid-1990s, driven by rapid industrialization and urbanization. By 2010, the global production of crude steel was approximately 1,414 million tonnes, while China alone produced about 627 million tonnes. This output accounted for nearly 44 percent of the total global production, easily surpassing the one-third mark. The massive scale of China's steel industry is supported by its extensive domestic iron ore and coal resources, alongside significant state investment in infrastructure and heavy manufacturing sectors. As of the early 2010s, its production volume was several times larger than that of any other individual country.

Explanation

Hamilton is located in the province of Ontario, Canada, and has historically been known as the Steel Capital of Canada because it hosts the country's largest iron and steel manufacturing plants. Birmingham is a prominent industrial city in the West Midlands of the United Kingdom that served as a powerhouse of the Industrial Revolution, particularly famous for its metalworking and steel industries. Essen is a central city in the Ruhr industrial region of Germany and was the historical headquarters of the Krupp industrial empire, making it a primary hub for German coal and steel production. Anshan is known as the Iron Capital of China and is home to the Anshan Iron and Steel Group, which was the first large-scale iron and steel complex established in the People's Republic of China.

Explanation

India has maintained its position as the largest milk producer in the world since 1998, a result of the systematic development of the dairy sector through initiatives like Operation Flood. By 2011, India was producing over 115 million tonnes of milk annually, combining output from both cows and buffaloes. The United States followed as the second-largest producer, with its production primarily concentrated in highly industrialized cow milk farming. China witnessed a massive expansion in its dairy industry during the 2000s, elevating it to the third position globally to meet rising domestic demand. Russia held the fourth position, supported by a large agricultural base and traditional dairy consumption patterns. This descending order reflects the global production statistics provided by the Food and Agriculture Organization (FAO) for the late 2000s and early 2010s.

Explanation

Let the labelled price of the watch be 100. Since Sonu bought the watch at a 30 percent discount on the labelled price, his cost price is 100 - 30 = 70. He then sold the watch at a 20 percent profit on the labelled price, making his selling price 100 + 20 = 120. The actual profit earned by Sonu is the difference between his selling price and his cost price, which is 120 - 70 = 50.

To find the percentage of profit relative to the price he paid, we use the profit percentage formula:

Profit Percentage = (Selling Price - Cost Price)/Cost Price × 100

Substituting the calculated values:

Profit Percentage = (120 - 70)/70 × 100 = 50/70 × 100 = 5/7 × 100 ≈ 71.42%

Given the options provided, the approximate profit percentage is 70.

Explanation

The given series follows a specific mathematical pattern where each term Tₙ is calculated using the formula Tₙ = n³ - n² or Tₙ = n²(n - 1), where n is the position of the term in the sequence.

By applying the formula to each position: For n = 1: 1³ - 1² = 1 - 1 = 0 For n = 2: 2³ - 2² = 8 - 4 = 4 For n = 3: 3³ - 3² = 27 - 9 = 18 For n = 4: 4³ - 4² = 64 - 16 = 48

The missing number is the fifth term in the series (n = 5). Calculating for n = 5: T₅ = 5³ - 5² = 125 - 25 = 100

To verify the pattern, the sixth term (n = 6) is: T₆ = 6³ - 6² = 216 - 36 = 180

The calculation aligns perfectly with the provided sequence, confirming the missing value.

Explanation

The series follows an alphabetical progression for each character position in the triplets. The first letters follow the sequence L → M → N → O, which is a constant increment of one position in the alphabet (+1). The next letter in this sequence is P.

The second letters follow the sequence x (24), T (20), P (16), and L (12), representing a constant decrement of four positions (-4). The next letter in this sequence is H (8). The third letters follow the sequence F (6), J (10), N (14), and R (18), representing a constant increment of four positions (+4). The next letter in this sequence is V (22).

Combining these gives the next term as PHV. The term Plague is the only option that begins with the letter P, matching the first letter of the next term in the sequence.

Explanation

The coding logic follows a three-step pattern: Swap the first and last letters of the word. Reverse the order of the intermediate (middle) letters. Increment each of those intermediate letters by one position in the alphabet (+1).

Applying this to COMPUTER: First and last letters (C, R) are swapped to become R and C. The intermediate letters are O, M, P, U, T, E. Reversing them gives E, T, U, P, M, O. Incrementing each reversed letter by +1: E→F, T→U, U→V, P→Q, M→N, O→P. Combining these gives RFUVQNPC.

Applying this to MEDICINE: The first and last letters (M, E) are swapped, so the code must start with E and end with M. The intermediate letters are E, D, I, C, I, N. Reversing them gives N, I, C, I, D, E. Incrementing each reversed letter by +1: N→O, I→J, C→D, I→J, D→E, E→F. Combining these gives the result EOJDJEFM.

Comparing this result to the given options, only option d) correctly starts with E and ends with M. Thus, based on the positions of the first and last letters, d) is the correct code.

Explanation

Let Avinash's total monthly income be x. He spends 2/5 of his income on rent, which leaves a remainder of 1 - 2/5 = 3/5 of his income. He then spends 3/4 of this remainder on other expenses, which means the final balance represents 1 - 3/4 = 1/4 of that remainder.

The savings can be expressed by the following equation: 1/4 × (3/5x) = 180

Simplifying the fraction: 3/20x = 180

To find the total income x, multiply both sides by the reciprocal of the fraction: x = (180 × 20)/3 x = 60 × 20 = 1200

Thus, the total monthly income is ₹ 1,200.

Explanation

The surface area S of a cube with side length a is determined by the formula S = 6a². Given that the surface area is 384 m², we can find the side length by solving the equation 6a² = 384. Dividing both sides by 6 yields a² = 64, and taking the square root of both sides gives a side length of a = 8 m. The volume V of a cube is calculated using the formula V = a³. By substituting the side length into this formula, we get V = 8³, which equals 512 m³.

Explanation

In a partnership business, the profit is distributed in the ratio of the product of the capital invested and the time period for which it is invested.

Investment of Manas (Iₘ) = ₹ 42,000 Time period for Manas (Tₘ) = 12 months Investment of Kamal (Iₖ) = ₹ 50,000 Time period for Kamal (Tₖ) = 12 - 7 = 5 months

The ratio of their profit shares (Manas : Kamal) is calculated as: Pₘ : Pₖ = (Iₘ × Tₘ) : (Iₖ × Tₖ) Pₘ : Pₖ = (42000 × 12) : (50000 × 5) Pₘ : Pₖ = 504000 : 250000 Pₘ : Pₖ = 504 : 250 = 252 : 125

The total parts of the profit are 252 + 125 = 377. Given the total profit is ₹ 30,160, Kamal's share is determined by: Kamal's Share = 125/377 × 30160 Kamal's Share = 125 × 80 = 10000

Thus, Kamal's share in the profit is ₹ 10,000.

Explanation

The relation can be deciphered by breaking down the statement from the perspective of Mohan. Mohan refers to the only daughter of his mother-in-law. Since a mother-in-law is the mother of one's spouse, her only daughter must be Mohan's wife. The statement identifies this woman as the mother of the girl being introduced. If the girl's mother is Mohan's wife, then Mohan is the girl's father.

Explanation

The series follows the mathematical pattern xₙ₊₁ = (xₙ × k) + k, where k is a decreasing integer. Applying this logic to the terms in the sequence:

65 × 4 + 4 = 260 + 4 = 264 264 × 3 + 3 = 792 + 3 = 795

Following this progression, the next term (where k = 2) should be: 795 × 2 + 2 = 1590 + 2 = 1592

To verify the pattern, we apply the next step (where k = 1) to this value: 1592 × 1 + 1 = 1592 + 1 = 1593

Since the calculated value 1592 correctly yields the subsequent term 1593, the number 1590 in the original series is incorrect.

Explanation

Raghu's present age is calculated by subtracting the 3 years from his future age, resulting in 15 - 3 = 12 years. Since Govind is four times as old as Raghu, Govind's current age is 4 × 12 = 48 years. Shyama's age is determined by the fact that Govind is 3 years older than her, meaning she is 3 years younger than him. Therefore, Shyama's present age is 48 - 3 = 45 years.

Explanation

According to the divisibility rule for 11, a number is divisible by 11 if the difference between the sum of its digits at odd positions and the sum of its digits at even positions is either 0 or a multiple of 11.

For the number 1X5X01, let us calculate these sums starting from the rightmost digit: Sum of digits at odd positions = 1 + X + X = 1 + 2X Sum of digits at even positions = 0 + 5 + 1 = 6

The difference is (1 + 2X) - 6 = 2X - 5. For the number to be divisible by 11, this difference must be a multiple of 11. Setting the difference equal to the first positive multiple: 2X - 5 = 11 2X = 16 X = 8

Since 8 is a single-digit integer, it satisfies the condition for the digit X.

Explanation

Let the present ages of Ram and Moti be 3x and 4x respectively, following the given ratio 3:4. Ten years ago, their ages were 3x - 10 and 4x - 10. The problem states that ten years ago, Ram's age was half of Moti's age, which is expressed by the equation 3x - 10 = 1/2(4x - 10). Multiplying the entire equation by 2 gives 6x - 20 = 4x - 10. Solving for x involves moving like terms to one side: 6x - 4x = 20 - 10, which simplifies to 2x = 10, and thus x = 5. The present age of Ram is 3 × 5 = 15 and the present age of Moti is 4 × 5 = 20. The total of their present ages is 15 + 20 = 35. A faster verification is to note that the sum of the ages must be a multiple of 3 + 4 = 7, and only 35 satisfies the condition that subtracting 10 from each component age (15-10=5 and 20-10=10) results in a 1:2 ratio.

Explanation

Let the four prime numbers be represented as a, b, c, and d. The problem states that the product of the first three numbers is a × b × c = 385 and the product of the last three numbers is b × c × d = 1001.

To isolate the first and last numbers, we divide the product of the last three by the product of the first three:

(b × c × d)/(a × b × c) = 1001/385

By canceling the common prime factors b and c from the numerator and denominator, we get:

d/a = 1001/385

To simplify the fraction 1001/385, we find the common divisors. Dividing both numerator and denominator by 7 gives 143/55. Further dividing both by 11 gives 13/5.

d/a = 13/5

Since a and d are prime numbers, it follows that the first number a = 5 and the last number d = 13. This is consistent with the prime factorization of the given products, where 385 = 5 × 7 × 11 and 1001 = 7 × 11 × 13.
