RRB NTPC UG Previous Year Paper 11 Aug 2025 - 9:00 AM - 10:30 AM

The Aravalli Hills in northwest India play a crucial role in the formation of the low-pressure trough during summer. As summer begins, these hills heat up rapidly, creating a thermal low that pulls in moist winds from the southwest monsoon. This initiates the trough's development, which later extends eastward. The Thar Desert (B) contributes to heating but doesn't structurally mark the trough's start. The Satpura Range (A) and Ganga Basin (D) are more eastward and not directly linked to the trough's origin.

Tay-Sachs disease (C) is a genetic disorder caused by a deficiency of the enzyme hexosaminidase, leading to lipid accumulation in brain cells. This results in progressive neurological deterioration. Alzheimer's (A) involves protein plaques, not lipid digestion issues. Parkinson's (B) is linked to dopamine deficiency, and Huntington's (D) is a chromosomal disorder causing motor dysfunction. The key distinction here is the enzyme's role in lipid metabolism.

Amylopectin is a branched component of starch, consisting of glucose units joined by α-1,4-glycosidic bonds (A) in linear chains and α-1,6 bonds at branch points. The primary linkages are α-1,4, so option A is correct. β-1,4 bonds (B) are found in cellulose, not amylopectin. α-1,6 bonds (C) are only at branches, not the primary structure. α-1,2 bonds (D) are not characteristic of amylopectin's structure.

Article 243F of the Indian Constitution sets the minimum age for contesting Panchayat elections at 21 years (C). This provision ensures that candidates have attained adulthood as per Indian law, which defines an adult as someone aged 18 or older but specifies 21 for electoral candidacy in local bodies. Options A (30) and D (25) are higher than required, while B (18) is the general adulthood age but not the electoral eligibility criterion here.

The Trilateral Cooperation briefing on health, trade, and IP in Geneva involved WHO (health), WIPO (intellectual property), and WTO (trade) (C). WHO focuses on global health, WIPO on intellectual property, and WTO on trade rules, making their collaboration relevant to the topics discussed. UNICEF (A) focuses on children's welfare, IMF (B) on monetary cooperation, and UNESCO (D) on education and culture, which do not align as directly with the specified areas of health, trade, and IP.

The Control Panel (C) is a system configuration tool in Windows, allowing users to adjust settings like display, network, and security. It is not a direct visual element on the desktop interface. The Start Menu (A) and Taskbar (B) are interactive desktop components for launching applications and managing open windows. The Recycle Bin (D) is a visible desktop icon for temporary file storage. So, the Control Panel's role as a settings adjuster distinguishes it from the other options.

The Revolt of 1857 led to increased distrust between Hindu and Muslim communities due to the British 'Divide and Rule' policy, which exploited religious divisions post-rebellion. Option A is correct as this divide was a significant negative consequence. Options B and C relate to economic impacts but are not directly tied to the revolt's immediate social effects. Option D is incorrect as the decline of Indian languages was a gradual colonial process, not a direct outcome of 1857.

INS Guldar, a decommissioned Indian Navy ship, was announced in 2025 to be converted into an underwater museum, promoting marine heritage. Option C is correct as INS Guldar's repurposing aligns with environmental and cultural preservation efforts. Other options refer to active or differently designated ships, making them incorrect.

Option A is marked correct. For this Current Affairs question on Defence Technology, focus on the key fact in the question and eliminate choices that do not match the event, term, person, place, or scheme mentioned.

Option B is marked correct. For this Current Affairs question on National Events, focus on the key fact in the question and eliminate choices that do not match the event, term, person, place, or scheme mentioned.

Ikea, approved for a �10,500 crore FDI proposal in 2013, is a Swedish company known for furniture retail. Option A is correct as Ikea's Swedish origin is well-documented. Options B, C, and D are incorrect, as Ikea is neither Chinese, American, nor German, reflecting common misconceptions about multinational corporations.

Ghusadi is a tribal dance form of the Gond tribe in India, performed during festivals. Option D is correct as it directly relates to tribal culture. Options A and B refer to regional or folk dances (Bhangra, Lavani) not exclusively tribal, while Kathak (C) is a classical dance form, making them incorrect choices.

The answer depends on the main belief of moderate Congress leaders regarding British rule. Moderates, led by figures like Dadabhai Naoroji, believed in gradual constitutional methods to achieve political freedom. They did not seek immediate independence (B) or support violent uprising (C). While they cooperated with the British to an extent, 'Support for British' (D) is misleading as their goal was self-rule, not endorsement of British governance. (A) as it aligns with their ideology of incremental progress towards freedom is the answer.

The question pertains to Cambodia's action in 2025 regarding a border dispute with Thailand. The International Court of Justice (ICJ) (C) is the principal judicial organ of the UN and handles disputes between states. ASEAN Regional Forum (A) focuses on security dialogue, not adjudication. The UN Security Council (B) addresses threats to peace, but border disputes typically fall under the ICJ's jurisdiction. The WTO (D) deals with trade, not territorial issues. So, (C) is correct.

The Eran inscription highlights the qualities that led to Samudragupta's selection as king. The Guptas emphasized merit and virtue in governance. Option (A) mentions devotion, righteousness, and valour, which align with the inscription's description and the Gupta ethos. Wealth and popularity (B) were not the primary criteria for succession in this context. Support from other kings (C) relates more to alliances than legitimacy. Age and birthright (D) were less relevant here, as the focus was on personal qualities. Hence, (A) is correct.

The Tata Aircraft Complex for manufacturing C-295 aircraft was inaugurated in Vadodara (A) in October 2024. This project is part of India's defense modernization and Make in India initiative. Chennai (B) and Hyderabad (C) are hubs for IT and pharmaceuticals, respectively, not aerospace manufacturing. Pune (D) has a presence of automotive and engineering industries but is not associated with this specific project. (A) based on the location of the inaugurated facility is the answer.

The Bank of Madras was established as a Presidency Bank in 1843 (B). The Presidency Banks (Bank of Bengal, Bombay, and Madras) were set up in the mid-19th century to manage government finances. The year 1857 (A) is notable for the Revolt, not banking history. The Government of India Act, 1858 (C) postdates the bank's establishment. Option (D) 1840 is close but incorrect, as the Bank of Madras specifically was founded in 1843, making (B) the accurate choice.

The Indian Councils Act, 1892 (D) introduced the right of discussion on the budget in legislative councils, though without voting power. The 1861 Act (B) established the councils but did not permit budget discussions. The 1909 Act (A) is known for introducing separate electorates, not budgetary discussions. The 1858 Act (C) transferred authority from the East India Company to the Crown but did not address legislative council powers. So, (D) is correct as it directly relates to the budget discussion provision.

The term 'Maibis' refers to the designated female devotees who perform the Lai Haraoba dance in Manipur. This dance is a significant ritual in Meitei culture, symbolizing the cosmic dance of the universe. Option B is correct because 'Maibis' are priestesses in Manipuri tradition, distinct from 'Pujarin' (generic term for female priests) or 'Jogins' (ascetics). The other options do not specifically relate to Manipur's cultural context.

The book 'AI on Trial' was authored by Sujeet Kumar and Tauseef Alam, released in April 2025. This requires knowledge of recent publications. Option D is correct as the authors are directly associated with the book's title. Other options list unrelated individuals, such as political figures (Manohar Lal Khattar, Bandaru Dattatreya) or a police officer (Himanshu Roy), which are other choices.

The Kelkar Committee, headed by Vijay Kelkar, recommended simplification of direct taxes in post-liberalisation India (1990s). This aligns with fiscal consolidation strategies. Option B is correct as the Kelkar Committee is renowned for tax reforms. The Dutt Committee focused on indirect taxes, the Tarapore Committee on capital account convertibility, and the Narasimham Committee on banking reforms, making them incorrect.

LAN stands for Local Area Network, which connects computers within a limited area. Option D correctly pairs the abbreviation with its full form and primary function. ASCII (American Standard Code for Information Interchange) relates to character encoding, not LAN setup or graphic design, eliminating options A and C. CD (Compact Disc) stores data but not an operating system permanently, making B incorrect.

The 7th Khelo India Youth Games in 2025 were held in Bihar. This fact-based question requires awareness of recent national sports events. Option C is correct as Bihar hosted the event. Other states listed (Maharashtra, Haryana, Gujarat) may have hosted previous editions or other events, but not the 7th edition, making them other choices.

The 42nd Amendment (1976) added 'Socialist' and 'Secular' to the Preamble during the Emergency period. Option C is correct as this amendment is historically significant for these inclusions. The 24th Amendment dealt with the right to property, the 44th with the replacement of the word 'Lok Sabha' with 'House of the People', and the 39th with anti-defection laws, none of which relate to the Preamble's amendment, eliminating other options.

The Servants of India Society was established by Gopal Krishna Gokhale in 1905 to promote national education, social reform, and self-governance. Gokhale, a key figure in the Indian National Congress, emphasized the need for educated Indians to serve the nation. Option C is correct because Gokhale's role as the founder is well-documented. Options A and B refer to other leaders associated with different movements or organizations, while D, Bal Gangadhar Tilak, was a prominent extremist leader but not linked to this specific society.

UDAY stands for Ujwal DISCOM Assurance Yojana. Launched in 2015, it aimed to improve the financial health of power distribution companies (DISCOMs) through restructuring their debt and improving operational efficiency. Option A is correct as it accurately represents the full form. Other options either misinterpret the acronym (e.g., 'Blackbook' in A is part of the official name) or suggest unrelated meanings (B, C, D), which do not align with the scheme's objectives.

The Fiscal Health Index 2025 by NITI Aayog assesses states based on fiscal management, including revenue growth and expenditure efficiency. Odisha topped the index, reflecting strong financial governance. Option D is correct as per the report's findings. Other states like Maharashtra (A) and Gujarat (C) are economically strong but may not have led in this specific ranking, while Karnataka (B) is known for IT growth but not necessarily fiscal health leadership.

As per the Ministry of Coal data for 2023-24, Odisha has the largest coal reserves in India, primarily due to extensive mining in regions like the Ib Valley and Talcher. Option B is correct. Jharkhand (D) and Madhya Pradesh (C) also have significant coal reserves but are surpassed by Odisha. Telangana (A) is not a major coal-producing state, making it an incorrect choice.

Part XII of the Indian Constitution deals with the financial relations between the Centre and the States, covering aspects like taxation, grants, and fiscal responsibilities. Option B is correct as it directly addresses these financial provisions. Other parts, such as Part XIII (A) on trade and Part X (C) on emergency provisions, are unrelated to financial relations, making them incorrect choices.

The 19th India Digital Summit in January 2025 was hosted by the Internet and Mobile Association of India (IAMAI), which focuses on promoting the digital ecosystem in India. Option D is correct as IAMAI is a key organization in the digital sector. NASSCOM (A) primarily represents the IT and software industry, TRAI (B) regulates telecommunications, and CII (C) is a broader industry body, none of which specifically hosted this summit.

Key point: understanding factors affecting biodiversity in island ecosystems. Lakshadweep's smaller land area limits habitat diversity, and the absence of forests reduces niches for species, directly lowering biodiversity. Option D identifies these factors. Volcanic origin (C) is more relevant to the Andaman and Nicobar Islands. Human population (B) and altitude (A) are not primary factors in this comparison, as both island groups have relatively low elevation and population density isn't the key differentiator.

This checks administrative structures under the Delhi Sultanate. The Diwan-i-arz (C) was specifically responsible for military affairs, including recruitment, salaries, and organization, during Alauddin Khilji's reign. Other options relate to different functions: Diwan-i-wizarat (B) handled finance, Diwan-i-risalat (A) managed religious matters, and Diwan-i-insha (D) dealt with correspondence. Recognizing the specialized roles of these departments is crucial for eliminating incorrect options.

The question assesses familiarity with India's neighboring countries and bordering states. Bihar (C) shares an international border with Nepal, particularly along the Terai region. Meghalaya (A) borders Bangladesh, Odisha (B) does not share a border with Nepal, and Himachal Pradesh (D) borders Pakistan and China but not Nepal. Knowing the geographical layout of northern Indian states helps quickly identify the correct answer.

New Caledonia's status as an overseas territory of France (A) is the key fact. The region has experienced protests related to nickel mining and independence movements, which were widely reported. Eliminating other options requires basic knowledge of global territories: Australia (B) and New Zealand (C) are independent countries, and the UK (D) has different overseas territories, such as the Falklands. Contextualizing the political status of Pacific islands aids recall.

The National Clean Air Programme (NCAP) (B), launched in 2019, aims to reduce particulate matter levels in designated cities. This flagship program of the MoEF&CC targets air quality improvement through collaborative efforts. Other options are either subsequent initiatives (A, C) or unrelated international bodies (D). Recognizing the launch year and the program's scope helps distinguish the correct answer from similar-sounding environmental projects.

Diazonium salts are characterized by the presence of the -N�� group directly attached to an aryl or alkyl group (R-N��, where X� is a counterion). Option B correctly represents this structure. Other options depict different functional groups: A shows an isocyanide, C a nitrile, and D an urea derivative. Understanding the general formula for diazonium compounds is essential to identifying the correct molecular structure.

The Bharat 6G Vision aims to position India as a global leader in 6G technology by 2030. Option C is correct because it aligns with the initiative's goal to drive indigenous innovation and development. Option A is incorrect as the vision isn't limited to urban areas. Option B is false since 5G replacement isn't the focus by 2025. Option D contradicts the vision's emphasis on self-reliance, not imports.

The 97th Amendment to the Constitution amended Part IXB to promote co-operative societies. Option C is correct because Part IXB specifically deals with cooperatives, introduced by this amendment. Options A (Part XI - Distribution of Powers) and B (Part XII - Finance) are unrelated. Option D (Part IXA - Municipalities) refers to local governance, not cooperatives.

Life expectancy in India increased to 72 years by 2023, the highest since records began. Option D is correct, reflecting sustained improvements in healthcare. Options A (75), B (70), and C (65) are either overestimated or outdated, as historical data shows a gradual rise from 58.6 years in 1990, making 72 the accurate figure for 2023.

The Israel-Iran conflict escalated in June 2025 due to an Israeli preemptive strike on Iranian nuclear facilities (Option A). This event directly triggered heightened tensions. Option B refers to the JCPOA collapse, which is a broader context but not the immediate trigger. Options C and D describe subsequent or unrelated actions, not the specific June 2025 escalation.

Let pen cost = p, pencil = c. From the problem: 2p + 19c = 118 and 5(p-5) + 8(c+4) = 144. Simplify the second equation: 5p - 25 + 8c + 32 = 144 � 5p + 8c = 137. Solve the system: Multiply first equation by 5 (10p + 95c = 590) and second by 2 (10p + 16c = 274). Subtract: 79c = 316 � c = 4. Substitute c = 4 into first equation: 2p + 76 = 118 � p = 21. Original cost of 14 pens and 6 pencils: 14*21 + 6*4 = 294 + 24 = 318. Option C is correct.

Given 39% of the first number (F) equals 8/9 of the second number (S): 0.39F = (8/9)S. Rearrange to find F/S = (8/9)/0.39 = (8/9)/(39/100) = (8*100)/(9*39) = 800/351. So, the ratio is 800:351. Option A is correct. Other options do not simplify to this exact ratio, making them incorrect.

To find the overall average, first calculate total runs in 23 matches: 23 * 41 = 943. Then, total runs in next 10 matches: 10 * 14 = 140. Total runs in 33 matches: 943 + 140 = 1083. Overall average = 1083 / 33 � 32.82. Option B is correct because it accurately reflects this calculation. Common mistakes might involve miscalculating totals or misapplying the average formula, but the steps here are straightforward.

Convert speed to km/min: 42 km/hr = 0.7 km/min. Distance = speed * time = 0.7 * 5.4 = 3.78 km. Option B is correct as it directly results from unit conversion and multiplication. The other choices likely arise from incorrect unit conversions or arithmetic errors.

Total cost for 79 plates = â�?s¹79. After breakage, 66 plates remain. Selling price per plate = â�?s¹5.90, so total revenue = 66 * 5.90 = â�?s¹389.40. Profit = Revenue - Cost = 389.40 - 79 = â�?s¹310.40. Option A is correct. Errors might occur in calculating remaining plates or total revenue.

Option D is marked correct. For this Mathematics question on Ratio and Proportion, set up the formula or relation first, substitute the values carefully, and then compare the result with the options.

Total literate population = 22% of 359,000 = 78,980. Literate males = 22% of 179,000 = 39,380. Literate females = 78,980 - 39,380 = 39,600. Total females = 359,000 - 179,000 = 180,000. Percentage of literate females = (39,600 / 180,000) * 100 = 22%. Option C is correct as calculations directly support it. Misinterpretation of percentages or populations could lead to incorrect options.

Given 9A = 3B = 7C = k. Express A, B, C in terms of k: A = k/9, B = k/3, C = k/7. Total amount = 74,000 = k/9 + k/3 + k/7. Finding a common denominator (63): 7k + 21k + 9k = 37k = 74,000 * 63. Solving for k gives k = (74,000 * 63) / 37. Then, A = k/9 = (74,000 * 63) / (37 * 9) = 74,000 / 37 * 7 = 2,000 * 7 = 14,000. Option D is correct. Errors may occur in setting up equations or solving for k.

Key point: decimal arithmetic. To solve, recognize that the question involves basic addition or subtraction of decimals. The correct answer, 17.15, fits because it aligns with precise calculation steps. The other choices like 12.19 or 14.54 might result from miscalculations, such as incorrect placement of the decimal point or arithmetic errors. Ensuring accurate decimal alignment during calculation is crucial.

This checks divisibility rules. The number 740705 ends with a 5, making it divisible by 5, which is why option A is correct. Other options (9, 12, 4) do not have straightforward divisibility rules that apply here. For instance, 9 requires the sum of digits to be divisible by 9, which isn't the case. Focusing on the last digit for 2 and 5 divisibility is key.

This question assesses pattern recognition in number series. The correct option, 7,491, continues the logical sequence. Analyzing differences between numbers or their digits reveals the pattern. The other choices (7,504, 7,484, 7,489) might follow a similar but incorrect progression, such as adding/subtracting a consistent value or altering the wrong digit position.

Option D is marked correct. For this Mathematics question on Simple Interest, set up the formula or relation first, substitute the values carefully, and then compare the result with the options.

The problem involves finding the highest common factor (HCF) with remainders. The approach is to subtract the remainders from the numbers: 527 - 7 = 520 and 632 - 8 = 624. Then, find the HCF of 520 and 624. Factoring both: 520 = 2^3 * 5 * 13, 624 = 2^4 * 3 * 13. The HCF is 2^3 * 13 = 8 * 13 = 104. So, option B is correct. The other choices might result from incorrect remainder subtraction or miscalculating the HCF.

First, apply the trade discount: 20% off 10,000 = 10,000 * 0.8 = 8,000. Then, apply the scheme discount: 10% off 8,000 = 8,000 * 0.9 = 7,200. Finally, apply the cash discount: 5% off 7,200 = 7,200 * 0.95 = 6,840. The correct answer, A, reflects this sequential discount application. The other choices might combine discounts incorrectly (e.g., adding percentages) or apply them in the wrong order, leading to higher final prices.

The relationship between HCF, LCM, and the two numbers is HCF � LCM = Product of the two numbers. Given HCF = 91, LCM = 546, and one number = 182, we can find the other number by dividing (91 � 546) by 182. Calculating 91 � 546 = 49786, then 49786 ÷ 182 = 273. So, the correct answer is 273. Option C is the given number, not the one to find, and options A and D do not satisfy the HCF-LCM relationship.

Let the son's age be S and father's age be F. From the problem: 5S + F = 79 and S + 2.5F = 94. Solve the system of equations. Multiply the second equation by 5: 5S + 12.5F = 470. Subtract the first equation: 11.5F = 391, so F = 391 ÷ 11.5 = 34. Option D is correct. Other options do not satisfy both equations when checked.

Prime numbers between 466 and 476 are 467, 479 is beyond 476, and 473 is not prime (divisible by 11 and 43). Only 467 is prime in this range. Option B claims 3 primes, which is incorrect. Option A (1) is correct, though 'Blackbook' is irrelevant here. Options C and D overcount.

The ratio of investments is 1350:1470:1380, which simplifies to 135:147:138 (dividing by 10) and further to 45:49:46 (dividing by 3). Total parts = 45 + 49 + 46 = 140. Isha's share = (46/140) � 1330 = 437. Option C matches. Other options do not align with the ratio calculation.

Let the original number be N. 160% of N = 3550. So, N = 3550 ÷ 1.6 = 2218.75. Option C is correct. Options A and B miscalculate the percentage increase, and D doubles the result incorrectly.

Total distance = 282 + 120 + 496 = 898 km. Total time = 282/47 + 120/20 + 496/62 = 6 + 6 + 8 = 20 hours. Average speed = Total distance ÷ Total time = 898 ÷ 20 = 44.9 km/hr. Option C is correct. Other options miscalculate total time or distance.

The largest circle inside a rectangle has a diameter equal to the shorter side of the rectangle. Here, the shorter side is 217 m, so the radius is 217/2 = 108.5 m. Circumference = 2 * � * radius � 2 * 3.14 * 108.5 � 682 m. Option D is correct because it matches the calculated circumference. Options A, B, and C are incorrect as they do not align with the calculation using the shorter side.

Option A is marked correct. For this Mathematics question on Algebra, set up the formula or relation first, substitute the values carefully, and then compare the result with the options.

The question appears incomplete as it only states '9' without a clear problem. However, looking at the options and the correct answer D (11x² - 3x - 2), it suggests a factorization problem. If the original expression was something like 11x² - 3x - 2, it's already in its simplest form or correctly factored, making D the right choice. Other options either have incorrect signs or terms.

The marked price is �800, and the discount is 25%. To find the selling price: 25% of 800 = 0.25 * 800 = �200. Selling price = 800 - 200 = �600. Option B is correct. Other options miscalculate the discount amount or percentage application.

Option B is marked correct. For this Reasoning question on Coding-Decoding, write the sequence, code, or arrangement step by step and verify the pattern before finalising the answer.

Analyzing the pairs: QL-PS (Q to P is -1, L to S is +5), TO-SV (T to S is -1, O to V is +5), KF-JM (K to J is -1, F to M is +5). NI-MO (N to M is -1, I to O is +5) also follows the same pattern. However, the correct answer is C, indicating a potential mistake in the explanation or question, as all pairs seem to follow the pattern. Re-evaluation may be needed.

Key point: understanding ranking from both top and bottom. Vijay's rank from the top is 12th, and from the bottom is 34th. To find the total number of students, add the ranks and subtract 1 (since Vijay is counted twice). Calculation: 12 + 34 - 1 = 45. Option B (45) is correct because it accounts for the overlap. Options A, C, and D are incorrect due to miscalculations of the overlap or addition errors.

The series progresses by moving forward in the alphabet. Analyzing the pattern: EHR to LOY (each letter shifts +9, +10, +11), LOY to SVF (+9, +10, +11), SVF to ZCM (+9, +10, +11). Following this, the next shift should be +9, +10, +11 from ZCM, resulting in GJT. Option D fits the pattern. Other options deviate in the shift sequence or letter positions.

Key clues: V and T have three people between them; U is immediately left of T; C is at the far right; two people between C and U; W is immediately right of A. Deductive placement shows the order as A-W-B-C-U-T-V (with B and W having two people between them). Option C (Two) is correct. Other options miscount the positions between B and W due to incorrect sequencing.

The task is to identify symbols flanked by another symbol and a number. Scanning the series from left to right: @ > 5, # ? \\, + * 2, > ? >, $ 4, % %, $ 7, 4 2. Valid instances are @ > 5, # ? \\, + * 2, > ? >. This gives four occurrences. Option B (Four) is correct. Other options undercount or misidentify the symbol-number-symbol pattern.

The logic involves rotating the letters. SONG to OSNG (shift right), OSNG to GNOS (shift right). Applying the same to HEAT: EHAT (shift right), EHAT to TAEH (shift right). The next in the pattern should follow a right shift. Option B (FUSE - UFSE - ESUF) matches the rotation logic. Other options use incorrect shifts or sequencing.

From the clues: Q is left of N, two between N and R, two between L and Q, O is right of P. Constructing the arrangement: L _ Q N _ R, with P and O at the start. The sequence becomes P-O-L-Q-N-_-R, placing M in the third position. Option A (M) is correct. Other options misplace individuals based on the given conditions.

Key point: substitution coding where each word is replaced by a code. In the first statement, 'month owl row' is coded as 'eg kv oc', indicating 'row' corresponds to 'eg'. The second statement 'vex row virus' is coded as 'jl vf eg', confirming 'row' is 'eg'. Options A, C, and D are codes for other words, so option B is correct.

The statements establish that all watches are belts and no belt is a tie, creating a categorical exclusion. Conclusion I is invalid because watches cannot be ties. Conclusion II is also invalid as ties cannot be belts. So, neither conclusion follows, making D the correct choice.

The logic involves rotating the letters one position to the right in each step. For 'SKIP' to 'KSPI' to 'PIKS', each letter shifts right. Applying this to 'MEND' yields 'EMDN' then 'DNEM'. Among options, 'KITE' to 'IKET' to 'ETIK' follows the same rotation pattern, making B correct.

Analyzing Aman's movements: 10m north, 5m east, 6m south, 12m west, and 4m north. Net displacement is 10m -6m +4m = 8m north and 5m -12m = -7m east (i.e., 7m west). However, the item asks for the shortest distance to the starting point, which is the straight-line distance calculated using Pythagoras: sqrt(8^2 +7^2) is not directly relevant. The correct interpretation is the net position is 8m north and 7m west from the end point, so to return, he must go 7m east and 8m south, but the options simplify to the net east-west movement. 7m east, option B is the answer.

Given E @ F + G $ M �f· N, decoding the relationships: E is the wife of F, F is the brother of G, G is the daughter of M, and M is the father of N. So, E is the wife of F, who is the brother of G (and hence N's uncle), making E the brother's wife of N. Option D identifies this relationship.

The question seems incomplete as it references a statement about Rajesh's rank but asks about the number of students in the class. However, if Rajesh is 25th from the top and 35th from the bottom, the total number of students is 25 + 35 -1 = 59. This calculation accounts for Rajesh being counted in both positions. So, option D is correct.

Key point: determining the number of people between two individuals based on their positions in a line. Savitha is 11th from the right, so her position from the left needs to be calculated. If the total number of people is not given, the question might be incomplete. However, assuming standard positioning logic, if Savitha is 11th from the right, there are 10 people between her and the right end. Without knowing Deepa's exact position, the answer cannot be directly calculated. But since the correct answer is 10, it implies that Deepa's position is such that the difference between their positions results in 10 people in between. This requires understanding relative positioning and subtraction to find the number of people between them.

This checks the ability to identify patterns in letter clusters. Each pair in the options follows a specific rule. For GK-BF, G to B is moving 5 letters back (G is the 7th letter, B is the 2nd), and K to F is moving 5 letters back (K is 11th, F is 6th). Similarly, LP-GJ: L to G is 5 back, P to J is 5 back. SW-NQ: S to N is 5 back, W to Q is 5 back. UY-PS: U to P is 5 back, but Y to S is 6 back, breaking the pattern. However, the correct answer is A (GK-BF), indicating a different pattern. The core pattern might involve the difference in positions between the letters. GK-BF: G (7) - B (2) = 5, K (11) - F (6) = 5. LP-GJ: L (12) - G (7) = 5, P (16) - J (10) = 6, which breaks the pattern. This inconsistency suggests the correct odd one out is A, as the others might follow a different rule, such as alternating or varying differences.

The question involves substituting symbols with operations and solving the equation. Given: A = of (multiplication), B = ? (unknown operation), C = + (addition), D = - (subtraction). The equation is 100 A 5 C 14 D 5 B 3 = ?. Substituting known values: 100 * 5 + 14 - 5 B 3. This simplifies to 500 + 14 - 5 B 3 = 514 - 5 B 3. To find B, we need the equation to equal 19. So, 514 - 5 B 3 = 19. Rearranging, 5 B 3 = 514 - 19 = 495. So, B represents division: 5 / 3 is not possible, but if B is a two-digit number operation or a different symbol, it might be 495 / 5 = 99, which doesn't fit. However, the correct answer is 19, suggesting B could be a subtraction or a specific operation that results in 495 when 5 B 3 is calculated. This requires understanding the substitution rules and applying them step-by-step to solve for the unknown operation.

The series is 8, 13, 31, 40, 76, 94, 148, ?. The pattern alternates between adding 5 and multiplying by a certain number. 8 + 5 = 13, 13 * 2 + 5 = 31, 31 + 9 = 40, 40 * 1.9 � 76, 76 + 18 = 94, 94 * 1.57 � 148. However, the exact pattern might be: +5, *2 +5, +9, *2 -4, +18, *1.57. This inconsistency suggests a different approach. Alternatively, the pattern could be: 8 +5=13, 13*2+5=31, 31+9=40, 40*1.9=76, 76+18=94, 94*1.57�148. The next step would be 148 + 27 = 175, fitting option C. Key point: identifying the alternating addition and multiplication pattern, which increases in the added number each time.

The item asks to identify the odd one out based on a specific pattern. Each pair in the options follows a rule. EH - DG: E to D is -1, H to G is -1. GJ - FI: G to F is -1, J to I is -1. KR - GT: K to G is -4, R to T is +2, which breaks the pattern. MP - LO: M to L is -1, P to O is -1. The correct answer is C (KR - GT) because it doesn't follow the consistent -1 pattern for both letters in the pair. Key point: recognizing the consistent decrease in letter positions across the pairs, which KR - GT deviates from.

The series is 5 * # 7 % £ 9 4 $ 3 & @ 8 ?z¦ $ 1 6 & # 2. The task is to find symbols immediately preceded and followed by numbers. Checking each symbol: * is between 5 and # (not a number), # is between * and 7 (preceded by *, not a number), % is between 7 and £ (not a number), £ is between % and 9 (not a number), $ is between 4 and 3 (both numbers), & is between 3 and @ (not a number), @ is between & and 8 (not a number), ?z¦ is between 8 and $ (not a number), $ is between ?z¦ and 1 (not a number), & is between 6 and # (not a number), # is between & and 2 (not a number). Only $ is between 4 and 3, but 3 is a number, and $ is between 4 (number) and 3 (number). However, the correct answer is One, indicating only one such symbol exists. This requires carefully checking each symbol's position relative to numbers in the series.

Option B is marked correct. For this Reasoning question on Direction Sense, write the sequence, code, or arrangement step by step and verify the pattern before finalising the answer.

The number 6317458 is arranged in descending order. The digits in descending order are 8,7,6,5,4,3,1. The third digit from the left is 6, and the second from the right is 3. Their sum is 6+3=9. The correct option is A. A common mistake could be miscounting the positions, especially from the right. For example, if one mistakenly takes the second digit from the right as 4, the sum would be incorrect. Key point: to correctly identify the positions after rearrangement.

The series is 44, 55, 68, 83, 100, ?. The pattern involves adding 11, then 13, then 15, then 17, increasing the difference by 2 each time. So 44+11=55, 55+13=68, 68+15=83, 83+17=100. The next difference should be 19, making the next term 100+19=119. Option C is correct. A distractor might assume a different pattern, such as consistent differences, leading to incorrect options like 124 or 112.

The given sets (384, 32, 6) and (408, 68, 3) follow a pattern where the second number is derived from the first, and the third from the second. For 384: 3+8+4=15, and 384 ÷ 12=32. Then 32 ÷ 16=2, but 6 is given, indicating a possible alternative logic. Alternatively, 384 - 32*6 = 384 - 192 = 192, which doesn't fit. A clearer pattern is needed. Observing the options, the correct set (416, 52, 4) might follow 416 ÷ 8=52, and 52 ÷ 13=4. The exact pattern isn't explicitly clear, but the correct answer is C, suggesting a division or subtraction relationship that maintains consistency with the given examples. Key point: to identify the operations applied to the whole numbers without breaking them into digits.

The relation between GT 23 and FP 6, and HP 21 and GL 4, involves a shift in letters and a mathematical operation on numbers. GT to FP: G->F (back 1), T->P (back 4 in the alphabet, considering T is 20th and P is 16th). The numbers 23 to 6: 23-17=6. Similarly, HP 21: H->G (back 1), P->L (back 4, P is 16th, L is 12th), and 21-17=4. Applying this to OL 15: O->N (back 1), L->H (back 4, L is 12th, H is 8th), and 15-13=2 (since 17 was subtracted before, but here it seems inconsistent; perhaps subtract 13). So, OL 15 becomes NH 2. Option B is correct. The main logic is consistent letter shifting and number subtraction, with possible variations in the number operation that need careful tracking.

Option B is marked correct. For this Reasoning question on Alphabet Series, write the sequence, code, or arrangement step by step and verify the pattern before finalising the answer.

The series consists of squares of prime numbers: 7²=49, 9²=81, 11²=121, 13²=169, so the next prime is 15, 15²=225. Option B fits as the next term. Options A, C, D are not squares of primes in the sequence.

Option B is marked correct. For this Reasoning question on Coding-Decoding, write the sequence, code, or arrangement step by step and verify the pattern before finalising the answer.

Option D is marked correct. For this Reasoning question on Coding-Decoding, write the sequence, code, or arrangement step by step and verify the pattern before finalising the answer.

Statements: All hands are legs (H � L), Some legs are faces (L � F � �). Conclusions: I) All legs are hands (L � H) � incorrect, the original statement is the converse. II) All faces are legs (F � L) � incorrect, only some legs are faces. So, neither conclusion follows. Option D is correct.

Key point: identifying government initiatives aimed at economic growth. Make in India focuses on manufacturing and attracting foreign investment, directly aligning with the question. Skill India (A) emphasizes skill development, Startup India (B) supports startups, and Digital India (C) promotes digital infrastructure. These do not directly address manufacturing or foreign investment, making D the correct choice.

The Paris Agreement was adopted in 2015 at COP21, aiming to limit global warming. The year 2015 is significant as it marks a global consensus on climate action. Options like 2005 (Kyoto Protocol) and 1999 (no major climate agreement) are other choices. Recognizing the timeline of major UN conferences helps eliminate incorrect choices.

This question assesses knowledge of international agreements. The 2030 Agenda for Sustainable Development, which includes the 17 Sustainable Development Goals (SDGs), was adopted in 2015 by UN Member States. Option A is correct, as the adoption occurred through the UN General Assembly in September 2015. Options B, C, and D are incorrect, as they either predate or follow the actual adoption year.

Option A is marked correct. For this Mathematics question on Number Operations, set up the formula or relation first, substitute the values carefully, and then compare the result with the options.

This question evaluates advantages of transport modes. Road transport's main benefit is door-to-door service (C), providing flexibility for short and irregular routes. Railways are more economical for long distances (A and B), but roads offer last-mile connectivity. Environmental friendliness (D) is not a primary advantage of roads, as they often contribute to pollution. The focus should be on accessibility rather than cost or speed for this comparison.

The development of railways in India began in the mid-19th century under British rule, with the first passenger train running in 1853. Option B (19th century) is correct as this period marked the pioneering phase of railway expansion. Options A (18th) and D (17th) predate railway development, while the 20th century (C) saw expansion but not the initial pioneering phase.
