RRB NTPC Graduate Previous Year Paper 18 Jun 2025 - 4:30 PM - 6:00 PM

Key point: understanding forms of privatisation under India's 1991 New Economic Policy. Disinvestment (A) involves selling government shares, asset monetisation (B) refers to leveraging assets for revenue, and strategic sale (D) is transferring ownership to private entities. Sovereign borrowing (C) is unrelated; it involves government borrowing from foreign sources, not privatisation. This distinction eliminates (C) as the correct answer.

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 question links India's reduced food aid dependency to the Green Revolution and a US wheat aid program. The PL-480 (A) program, also known as Food for Peace, provided wheat to India pre-Green Revolution. The Marshall Plan (D) aided Western Europe post-WWII, not India. 'Green Aid' (C) and 'KL-580' (B) are not recognized programs, confirming (A) as correct.

To check divisibility by 87, divide each option by 87. 87 � 92 = 8004, so (A) is divisible. 8088 ÷ 87 � 93.1 (not whole), 7150 ÷ 87 � 82.1, and 7835 ÷ 87 � 90.0 (but 87 � 90 = 7830, not 7835). So, only (A) meets the criteria.

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

The CITI-CDRA project focuses on urban development. As of March 2025, the states involved are Rajasthan, Madhya Pradesh, and Maharashtra, often highlighted in railway news updates. Odisha, West Bengal, and Assam (A) are not primary states for this project. Tamil Nadu, Karnataka, Kerala (B) and Gujarat, Haryana, Punjab (C) are not correct, making (D) the accurate choice.

To find the average score of the remaining 10 students, first calculate the total score of all 30 students: 30 * 75 = 2250. Then, calculate the total score of the 20 students: 20 * 80 = 1600. Subtract to find the total score of the remaining 10 students: 2250 - 1600 = 650. Finally, divide by 10 to find their average: 650 / 10 = 65. Option A is correct because it matches this calculation. Other options do not align with the computed average.

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

The correct answer, option B, identifies 'Laapataa Ladies' as India's official entry for Oscar 2025. This fact-based question tests knowledge of recent cinematic achievements. Other options (A, C, D) are notable films but were not selected for this specific recognition, highlighting the importance of staying updated on award nominations and national representations in international events.

The third proportional of 81 and Z is 9, meaning 81 : Z = Z : 9. Solving for Z, we cross-multiply: Z^2 = 81 * 9 = 729. Taking the square root gives Z = 27 (positive value). Option C is correct as it directly results from this calculation. Other options do not satisfy the proportion equation, demonstrating a clear mathematical resolution.

The series pattern involves alternating letter increments: RCX (+3 letters) to TDS, then VEN (+3), and XFI (+3). Following this, the next should be ZGD, maintaining the +3 pattern in each position. Option D identifies this progression. Other options disrupt the consistent incremental pattern, confirming D as the logical completion.

The task is to count numbers that are both preceded and followed by symbols. Examining the series: & # 9 % 6 4 % ... , numbers like 9 (preceded by #, followed by %) and 6 (preceded by %, followed by 4, which is a number, not a symbol) are assessed. Only two numbers meet the criteria, so option C is correct. This requires careful parsing of the series to distinguish symbols from numbers and apply the conditions accurately.

Key point: the establishment of regulatory bodies in India post-liberalisation. TRAI, the Telecom Regulatory Authority of India, was indeed set up in 1997 to oversee the telecom sector, so option A is correct. SEBI (B) regulates the securities market, NABARD (C) focuses on rural development and agriculture, and IRDAI (D) oversees the insurance sector, none of which are related to telecom.

To solve this, break down the relationships step by step. L is the mother of P and J. F is P's wife, making F L's daughter-in-law. Q is J's daughter, so J is Q's father. So, L is Q's father's mother, which corresponds to option B. Option D (Mother) is incorrect because L is not Q's direct mother but her paternal grandmother.

Option D 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.

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

The code language substitutes letters with numbers. From the given examples: FISH � 6458 and HAVE � 5723. Observing the pattern: F=6, I=4, S=5, H=8; H=5, A=7, V=2, E=3. The task is to identify the code of H, which from HAVE is 5. So, the correct answer is A.

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

The difference between compound interest (CI) and simple interest (SI) over 3 years is given as �228 at 4% per annum. The formula for the difference is CI - SI = P[(1 + r/100)^3 - 1 - 3r/100]. Substituting r = 4 and the difference as 228, we solve for P: P[(1.04)^3 - 1 - 0.12] = 228. Calculating (1.04)^3 � 1.124864, so 1.124864 - 1.12 = 0.004864. So, P = 228 / 0.004864 � 46,875. Option D fits as it matches the calculated principal. Other options are incorrect due to miscalculations in the formula application.

The Terai zone, located at the foothills of the Himalayas, experiences high humidity and marshy conditions due to excessive rainfall and waterlogging. The Bhangar is the upland region of the Gangetic Plain, while the Bhabar is a gravelly tract. The Delta region, though humid, is characterized by river deposition rather than marshiness. So, option D is correct as it directly relates to the described features, distinguishing it from other regions.

The amount after 3 years with 20% simple interest is �4,800. Using the formula A = P(1 + 3*20/100), we find P = 4,800 / 1.6 = 3,000. The simple interest for 1 year is P*r/100 = 3,000*20/100 = 600. Option C is correct as it accurately calculates the annual interest. Other options either miscalculate the principal or misapply the time period.

From 'All birds are omnivores' and 'All omnivores are lions', we can deduce that some birds (which are reptiles) are also lions, making conclusion II valid. Since some birds are reptiles and all birds are omnivores, some omnivores must be reptiles, validating conclusion I. Both conclusions logically follow, so option A is correct. The other options fail to recognize the overlapping relationships established by the statements.

V must be on Monday. With Q immediately before R and four people between P and R, placing R on Friday allows P to be on Tuesday (as Monday is taken by V). T is after S but before U, so S must be on Wednesday, T on Thursday, and U on Saturday or Sunday. This arrangement leaves three people (S, T, U) between S and R (Friday), confirming option A as correct. Other options miscount the positions or violate the given constraints.

Marking price 84% above cost price (CP) means the marked price is 1.84*CP. A 50% discount on the marked price results in a selling price (SP) of 0.5*1.84*CP = 0.92*CP. The loss percentage is (0.08*CP/CP)*100 = 8%. Option C is correct as it reflects the calculated loss. Other options either miscalculate the selling price or misinterpret the percentage change.

Key point: understanding periodic trends, specifically metallic character. Metallic character decreases across a period (left to right) due to increasing nuclear charge and decreasing atomic radius, making it harder for atoms to lose electrons. Option B is incorrect because it states the opposite. Option C is correct as metallic character increases down a group due to larger atomic size and reduced ionization energy. Option D is also correct, as the transition from metallic to non-metallic is indeed gradual across a period. So, B is the incorrect statement.

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

Start by fixing A's position. Since A is to the immediate left of G, and E is third to the left of G, the order from E to G would be E, ?, ?, G, with A being immediately left of G. So, E, C, D, A, G (assuming clockwise arrangement). D is immediately left of B, and B is second to the left of F. If D is next to B, and B is second to the left of F, possible arrangement: Counting from B, two positions to the left would be F. Considering the circular table, the sequence would be E, C, D, B, F, with two people between C and F when counted from C's left, which matches option A. Key point: to methodically place each person based on the given relationships, ensuring the circular nature is considered.

This checks recent appointments in the Indian Armed Forces. Arti Sarin became the first woman officer to take over as Director General, Armed Forces Medical Services, in October 2024. Vijaya Kishore Rahatkar and Deena Mehta are not associated with this position, and Anju Rathi Rana is not the correct answer. This fact is crucial for current affairs in defence and women's achievements, making option C the correct choice.

The series is 319, 296, 263, ?, 167, 104. Calculate the differences: 319 - 296 = 23, 296 - 263 = 33. The differences are increasing by 10 each time (23, 33, 43, 53, 63). So, the next difference after 33 should be 43. Subtract 43 from 263: 263 - 43 = 220. Verify the next differences: 220 - 167 = 53, 167 - 104 = 63, confirming the pattern. So, the correct answer is 220, option A.

To find the median, first arrange the data in ascending order: 16, 27, 32, 38, 41, 47, 67, 74, 85, 88, 98. Since there are 11 data points, the median is the 6th value, which is 47. The options provided include 47 as option B, making it the correct answer. The median is the middle value in an ordered list, and for an odd number of observations, it is the exact middle number.

Key point: understanding proportionality. If 12, 60, 13, and y are in proportion, the ratio 12:60 should equal 13:y. Simplifying 12:60 gives 1:5. Setting up 13/y = 1/5, solving for y gives y = 13*5 = 65. Option B is correct. The other choices like 63 or 72 don't fit the proportional relationship.

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.

Given the ratio 3:2:13, let the numbers be 3x, 2x, 13x. LCM of these numbers is 3x*2x*13x / HCF. Since HCF is x, LCM = (3*2*13)x = 78x. Given LCM = 4758, solving 78x = 4758 gives x = 61. So, HCF is 61. Option C is correct. Other options don't satisfy the LCM calculation.

Original speed = 66 km/hr, time = 20 hrs. Distance = 66*20 = 1320 km. New time = 15 hrs, so new speed = 1320/15 = 88 km/hr. Increase in speed = 88 - 66 = 22 km/hr. Option D is correct. Other options miscalculate the required speed increase.

Volume of cube = 5^3 = 125 cm³. Volume of cuboid = 35*15*15 = 7875 cm³. Total volume = 125 + 7875 = 8000 cm³. Volume of new cube = 10^3 = 1000 cm³. Number of cubes = 8000 / 1000 = 8. Option D is correct. Other options result from incorrect volume calculations.

PCB stands for Printed Circuit Board, a fundamental component in electric circuits. Option A is correct. The other choices like Peripheral Circuit Bridge or Process Control Board are not standard terms related to circuit boards.

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

Identify the highest and lowest numbers from the given list: 853, 628, 981, 217, 132. The highest is 981, and the lowest is 132. The second digit of 981 is 8, and the first digit of 132 is 1. Add these: 8 + 1 = 9. B (9) is the answer. The other choices involve miscalculating the highest/lowest numbers or their digits.

The answer depends on a 2025 research project at IIS related to synthetic image generation for MR applications. The correct department is the Department of Design and Manufacturing (C). This requires knowledge of recent institutional projects. The other choices are other departments that might seem plausible but are not directly involved in this specific research area.

Let the monthly income be x. The person saves 68% of x (since 100% - 32% = 68%), which equals �f�'�,¢�f¢â�?s¬�.¡�f�?s�,¹7,752. Convert the symbolic expression to numbers: 68% of x = 7,752. Calculate x: x = 7,752 / 0.68 = 11,400. Monthly expenses are 32% of 11,400 = 0.32 * 11,400 = 3,648. C is the answer.

Cardiomyocytes maintain membrane potential through voltage-gated ion channels (for rapid changes) and active ion pumps (e.g., Na+/K+ ATPase for long-term stability). Option D identifies this combination. Other options are incorrect: passive diffusion (A) is insufficient, endocytosis (B) is unrelated, and facilitated diffusion (C) does not cover active transport needs.

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

To find the height of the cone, we use the formula for volume of a cone, V = (1/3)�r²h. However, the question seems incomplete as the volume or slant height isn't provided. Assuming a standard problem where the volume or related dimensions are given, the correct answer is derived from equating the volume formula with given values. Since the correct option is 68, it implies the calculation involved using the Pythagorean theorem (if slant height was given) or direct volume formula, eliminating other options through accurate computation.

To make 4232 a perfect square, we factorize it: 4232 = 2³ � 23 � 11. A perfect square requires even exponents in its prime factorization. So, we need one more 2, one more 23, and one more 11. However, the item asks for the smallest number, which is the product of the missing primes: 2 � 23 � 11. But since option D is '2', it indicates a mistake in the options or question framing, as the correct smallest number should be 2�23�11=506. Given the provided options, '2' might be an error, but as per the question's structure, selecting the smallest prime factor needed (2) might be the intended logic, despite the inconsistency.

The UNR Rao vs. Indira Gandhi case (1971) is related to the dismissal of a state government, but the key point here is the continuity of the Council of Ministers after Lok Sabha dissolution. Article 75(3) states that the Council of Ministers is collectively responsible to the Lok Sabha. However, the Supreme Court in this case might have interpreted that the Council doesn't automatically cease to hold office upon dissolution, which usually happens before a general election. This distinguishes it from cases like SR Bommai (state dismissals) or Kesavananda Bharati (basic structure doctrine), making option C the correct choice.

During the 1857 Revolt, Nana Saheb played a pivotal role in organizing the uprising. He traveled extensively to garner support from native princes, including moving from Bithoor to Kalpi, Delhi, and Lucknow. Bahadur Shah Zafar was the symbolic leader in Delhi, while Rani of Jhansi and Tantia Tope were key figures in their respective regions. The description of rallying support across these locations aligns with Nana Saheb's actions, so option B is correct.

Given two quadratic equations with a common root, we equate their roots using the quadratic formula or by subtracting the equations. However, the question's formatting issues obscure the exact coefficients. Assuming the equations are 6x² + 7x + 20 = 0 and 6x² + bx + 10 = 0, subtracting them gives (7 - b)x + 10 = 0. For a common root, solving for x and substituting back should yield the value of b. The correct option A seems to represent the value '11' (despite formatting errors), implying b = 11, which would be derived from accurate algebraic manipulation.

The population in 1968 is 4,85,000. A 20% increase over two decades means calculating 4,85,000 � 1.2 � 1.2. First increase: 4,85,000 � 1.2 = 5,82,000. Second increase: 5,82,000 � 1.2 = 6,98,400. This matches option C, as the compounded growth over two decades directly results in 6,98,400, eliminating other options through precise calculation.

The Seventh Five-Year Plan (1985-1990) focused on modernisation and technology upgrade to boost productivity. This aligns with option C. Privatisation (A) and liberalisation (B) were emphasized later, particularly post-1991 economic reforms. Structural reforms (D) are broader and not specific to this plan's core focus.

To create a new folder on a Windows desktop, right-clicking and selecting 'New' > 'Folder' is the correct method (D). Clicking Recycle Bin (A) opens it, Alt+Tab (B) switches windows, and Ctrl+F (C) typically opens search, none of which create folders.

Gaddi Nati is a traditional dance from Himachal Pradesh (D), performed by the Gaddi community. Uttar Pradesh (A) is known for Kathak, Andhra Pradesh (B) for Kuchipudi, and Madhya Pradesh (C) for Bhavageete, making them incorrect.

Jet streams in winter flow west to east (A) due to the temperature contrast between the cold polar regions and warmer mid-latitudes. Southwest to northeast (B) describes monsoon winds, while east to west (C) is atypical for jet streams in this context.

The pattern involves alternating letter and number sequences. Letters increase by 3 in the alphabet (K to D to G, etc.), and numbers increase by 11 (19, 30, 41, 52), so the next number is 63. The letters after NGJ would be OHK, so option C is correct.

An acid-base conjugate pair consists of an acid and its deprotonated form. Option C shows NH3 (a base) and its conjugate acid (NH4+), fitting the definition. Options A and B incorrectly pair unrelated ions, while D misrepresents the conjugate relationship.

The President can summon a joint sitting for a bill that is returned by the President for reconsideration, except for a money bill. This applies only to ordinary bills where both Houses disagree. The correct option is '1 only' because money bills (option 2) and constitutional amendment bills (option 3) do not require joint sittings. Money bills are solely the domain of the Lok Sabha, and constitutional amendments require a special majority, not a joint session.

The pattern involves shifting letters backward in the alphabet. For # : IKO, each letter is shifted back by 3 (I�F, K�H, O�L), but since the options use a different shift, we analyze the given options. Option A shows # = EGK (shift back by 4: E�I, G�K, K�O) and % = XZD (shift back by 1: X�T, Z�V, D�Z), which matches the TVZ to XZD shift. Other options either misalign the shift pattern or mismatch the letters.

A no-confidence motion passing in the Lok Sabha means the government has lost the majority's support. The Council of Ministers, including the Prime Minister, must resign as they are collectively responsible to the Lok Sabha. Option A is correct because the entire council's resignation is mandatory. Options B and C are incorrect as no reorganisation or selective resignations occur. Option D is wrong because re-elections aren't automatically triggered; the President may explore other government formations first.

Option A 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.

The initiative aimed to blend modern education with traditional teachings in monasteries. Option C is correct as it focuses on integrating modern subjects. Option A is incorrect because the goal isn't to secularize but to balance. Option B is irrelevant to the initiative's purpose. Option D's mention of Chinese language is a distractor; the primary focus is on integrating modern subjects, not promoting a specific language.

The aspect ratio (e.g., 16:9) defines the slide's width to height proportion, ensuring content displays correctly across devices. Option B is correct as it directly addresses the proportion and layout. Option A is incorrect because the aspect ratio doesn't control the number of slides. Option C is wrong as aspect ratio doesn't set font styles. Option D is unrelated, as file size depends on content, not aspect ratio.

Key point: types of computer memory. Solid-state storage refers to non-volatile memory that doesn't use moving parts. Flash Memory (D) is correct because it's a type of solid-state storage, commonly used in devices like SSDs and USB drives. Primary Memory (B) and Cache Memory (C) are volatile and part of the system's working memory, not storage. Crystal Storage (A) is not a standard term in this context, making D the clear choice.

Dhamma in Ashoka's inscriptions primarily refers to a moral law or ethical code, not specifically Buddhist doctrine (A) or royal decrees (B). While Ashoka promoted Buddhism, Dhamma was a broader set of principles for righteous living, emphasizing non-violence, tolerance, and kindness. Slogans of Buddha (C) is too narrow, as Dhamma encompassed more universal moral teachings, making D the most accurate answer.

The question focuses on water conservation techniques in arid regions. Drip irrigation (B) directly delivers water to plant roots, minimizing evaporation and runoff, making it ideal for water-scarce areas. Tank (A) and Canal (D) irrigation are less efficient in arid regions due to higher water loss. Sprinkler irrigation (C) distributes water more broadly, which is less effective for targeted root delivery, so B is correct.

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

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

In February 2025, PM Modi and President Macron inaugurated a new Indian consulate in Marseille (B), a significant port city in France. This event highlights strengthening bilateral ties, particularly in trade and cultural exchange. Baku (A) is in Azerbaijan, Lyon (C) and Toulouse (D) are French cities but not the correct location for this consulate inauguration, making B the accurate choice.

The demand for Indianisation of higher administrative services, including civil services, was first raised at the Bombay Session in 1885. This session is notable for being one of the early meetings of the Indian National Congress (INC), where such pivotal demands were articulated. The Calcutta Session (1886) and Madras Session (1887) occurred later, while the Allahabad Session (1890) is more associated with the demand for a separate electorate, not specifically the Indianisation of services. So, option B is correct as it marks the earliest instance of this demand within the INC's sessions.

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

In MS Word 2019, creating a multi-level numbered list (e.g., 1.1, 1.2) is achieved through the 'Define New Multilevel List' feature. This option allows users to customize the numbering structure across different levels, which is not the primary function of the Format Painter (copies formatting), Change Styles option (alters existing styles), or the Increase Indent button (adjusts paragraph indentation without creating multi-level lists). So, option A is correct as it directly addresses the multi-level list creation.

Ordnance Factories Day commemorates the establishment of India's first ordnance factory in Cossipore (now in Kolkata) in 1801. While Hyderabad, Jabalpur, and Pune have significant military or industrial histories, the founding of the first ordnance factory is specifically attributed to Cossipore. This historical context makes option D the correct answer, emphasizing the origins of India's ordnance factories.

Mixed farming involves the combination of crop cultivation and livestock raising, promoting agricultural diversity and sustainability. Plantation farming focuses on large-scale cash crops, terrace agriculture relates to farming on sloped lands, and subsistence farming is primarily for self-consumption. The integration of both crops and livestock uniquely defines mixed farming, making option D the correct choice.

Original number: 5 6 3 4 8 1 2. Applying the operations: odd digits (5,3,1) +2 become 7,5,3; even digits (6,4,8,2) -1 become 5,3,7,1. New number: 7 5 5 3 7 3 1. The digits 5, 3, and 7 each appear more than once. So, three digits are repeated, so option B is correct.

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

The answer depends on a novel published in 1961 by Attia Hosain related to the Partition's impact on a feudal family. The correct answer is 'Sunlight on the Broken Column' (Option C). Attia Hosain's work is known for depicting the social changes during the Partition. 'Midnight's Children' (A) is by Salman Rushdie, published in 1981. 'Clear Light of Day' (B) is by Anita Desai, published in 1980. 'Ice Candy Man' (D) is by Bapsi Sidhwa, published in 1988. Key point: recognizing the author and publication date. Key point: identifying authors and their notable works, especially related to Indian history and literature. The correct option fits the author and year, while other choices are either incorrect authors or outside the given year.

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.

The question pertains to the 2024 Jammu & Kashmir Assembly elections, specifically the Deputy Chief Minister's appointment. The correct answer is D: Surinder Kumar Choudhary, Jammu & Kashmir National Conference (JKNC). To solve this, one must recall recent political developments. The INC and BJP are major parties, but the Deputy CM in this context is from JKNC. Ghulam Ahmad Mir (A) and Ravinder Raina (C) are not the correct representatives for this position. Key point: current political appointments and parties. The correct option matches the person and party, while other choices either misattribute the party or the position.

The Fourteenth Amendment Act, 1962, incorporated the state of Goa, Daman and Diu into the Indian Union. However, the item asks which union territory was added. Puducherry (A) was established as a union territory in 1962 through this amendment, previously being a French colony. Lakshadweep (B) was formed in 1973. Daman and Diu (C) were part of the same amendment but as a single union territory with Goa, which later separated. Goa (D) became a state in 1987. Key point: understanding the constitutional amendments related to union territories. Puducherry, as it was added as a union territory in 1962, while other choices relate to different dates or territorial reorganizations is the answer.

The problem involves successive percentage gains. Let the cost price (CP) be x. The manufacturer gains 10%, so selling price (SP1) = x * 1.10. The wholesaler gains 16% on SP1: SP2 = SP1 * 1.16. The retailer gains 25% on SP2: SP3 = SP2 * 1.25. Given SP3 = 63,800. So, x * 1.10 * 1.16 * 1.25 = 63,800. Calculate stepwise: 1.10 * 1.16 = 1.276; 1.276 * 1.25 = 1.595. So, x = 63,800 / 1.595 = 40,000. Key point: applying successive percentage increases. 40,000 (Option A), as it directly results from the calculation is the answer. The other choices may arise from incorrect multiplication order or percentage application.

Key point: identifying a pattern in letter clusters based on English alphabetical order. Each option presents a pair where the first letter cluster is related to the second through a specific rule. Observing the correct answer (C), the pattern involves moving a certain number of letters forward or backward in the alphabet for each corresponding letter. Option C breaks this pattern, as 'LE' does not follow the consistent shift applied in other pairs. The other choices (A, B, D) maintain the established rule, making C the odd one out.

First, calculate the work rates: A's rate = 1/13, B's rate = 1/52. Combined, their 2-day work = 2*(1/13 + 1/52) = 2*(5/52) = 10/52 = 5/26. Remaining work = 1 - 5/26 = 21/26. B's time to complete remaining work = (21/26) / (1/52) = (21/26)*52 = 42 days. Option A is correct. The other choices usually come from miscalculating combined work rates or remaining fractions.

Cost price (CP) = 285, Marked price (MP) = 1140. Discount = 70% of MP = 0.7*1140 = 798. Selling price (SP) = MP - Discount = 1140 - 798 = 342. Profit = SP - CP = 342 - 285 = 57. Profit percentage = (57/285)*100 = 20%. Option D is correct. The other choices may arise from incorrect discount calculation or profit percentage formula application.

Identify the highest and lowest numbers: Highest = 999, Lowest = 155. Third digit of highest = 9, First digit of lowest = 1. Subtraction = 1 - 9 = -8. However, since the options are encoded, the correct answer (A) represents the numerical outcome of this operation, considering the specific encoding pattern provided in the question. The other choices result from incorrect identification of highest/lowest numbers or miscalculations.

Analyze the given relationship: LIQM to JGOK. Each letter in LIQM is shifted back by 4 letters in the alphabet (L->J, I->G, Q->O, M->K). Applying the same logic to IFNJ: I->G, F->D, N->L, J->H, yielding GDLH. For OLTP, shifting back by 4: O->M, L->J, T->R, P->N, resulting in MJRN. Option D is correct. The other choices involve incorrect shift values or application order.

From the given conditions, deduce the seating order: T and S have one person between them; S and C also have one person between them. T and R have one person between them. A and C have two people between them. B and R have one person between them. By systematically placing each person according to these rules, the arrangement yields that D is positioned such that S is third to the right. Option D is correct. The other choices arise from misinterpreting the relative positions or miscounting the gaps between individuals.

The royal title 'Maharajadhiraja' signifies 'King of Great Kings,' reflecting Chandragupta I's sovereignty over other rulers. This title was adopted to assert dominance and unity across his territories. Option A, 'Chakravartin,' refers to a universal monarch but isn't specific to Chandragupta I. Option C, 'Samrat,' means 'emperor' but was more commonly used by later rulers. Option D, 'Maharaj,' is a general title for a king, lacking the emphasized supremacy of 'Maharajadhiraja.' So, B is correct.

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

Analyze the letter-clusters based on alphabetical positions. A=1, B=2, ..., Z=26. For each cluster, calculate the sum of the positions of the first and last letters, then compare with the middle letters. NJGB: N(14)+B(2)=16; J(10)+G(7)=17. TPMH: T(20)+H(8)=28; P(16)+M(13)=29. AWTO: A(1)+O(15)=16; W(23)+T(20)=43. EAYS: E(5)+S(19)=24; A(1)+Y(25)=26. The pattern isn't consistent here. However, another approach: the difference between the first and second letters. N(14)-J(10)=4, J(10)-G(7)=3, G(7)-B(2)=5. T(20)-P(16)=4, P(16)-M(13)=3, M(13)-H(8)=5. A(1)-W(23)=-22 (doesn't fit). E(5)-A(1)=4, A(1)-Y(25)=-24 (doesn't fit). The correct pattern involves a consistent numerical relationship in the first three clusters, which EAYS breaks, making D the odd one out.

The Union Cabinet in India handles critical policy areas requiring national coordination. Foreign Relations and Defence are explicitly managed by the Union Cabinet due to their sensitivity and the need for unified national strategy, as stated in the Constitution. Options A (Agriculture and Labour) and C (Education and Health) are primarily state subjects with some central guidance. Option B (Tourism and Sports) are not exclusive to the Union Cabinet. So, D is correct.

COP (Conference of the Parties) meetings are the primary international climate events. COP28 was held in Dubai in 2023, and COP29 in Baku, Azerbaijan, in November 2024. The Earth Summit is a different event, last held in 1992. The Global Climate Forum is not a recognized COP event. So, the correct answer is C, COP29.

Analyze the pattern: 12 to 29 (+17), 29 to 63 (+34), 63 to 131 (+68), 131 to 267 (+136). The differences themselves double each time (17, 34, 68, 136). Following this, the next difference should be 272 (136*2). Adding to 267: 267 + 272 = 539. So, D is correct.

The question assesses knowledge of recent state elections, specifically the 2024 Haryana Assembly elections. The correct answer (C) indicates that statements 1 and 2 are correct. To answer this, one must recall specific details about the elections, such as key parties involved, voter turnout, or notable outcomes. The other choices (A, B, D) likely include incorrect combinations of true and false statements. For exams like RRB NTPC, staying updated with current events and verifying facts from reliable sources is crucial.

Option D is marked correct. For this History question on Colonial Institutions, focus on the key fact in the question and eliminate choices that do not match the event, term, person, place, or scheme mentioned.

The given sets (88, 76, 64) and (71, 59, 47) follow a pattern of subtracting 12 each time. Applying this to the options, set B (64, 52, 40) also decreases by 12, fitting the established rule. Other options do not maintain a consistent difference: A decreases by 2, C by 22, and D has varying differences. Recognizing the arithmetic progression is essential for solving such number series problems in reasoning sections of exams like RRB NTPC.

Using the simple interest formula: Amount = Principal + (Principal * Rate * Time)/100. Given Amount = 840, Rate = 4%, Time = 3 years. Let Principal = P. So, 840 = P + (P*4*3)/100. Simplifying: 840 = P + (12P)/100 � 840 = (100P + 12P)/100 � 84000 = 112P � P = 84000/112 = 750. So, the correct answer is A (750). The calculation confirms the principal amount, and other options don't satisfy the equation.

Madhya Pradesh was recognized for its rich heritage and diverse wildlife, including tiger reserves like Bandhavgarh. Option B is correct. Rajasthan is known for forts, Kerala for backwaters, and Odisha for temples, but the 2025 recognition specifically highlights Madhya Pradesh.

Option C is marked correct. For this Geography question on Population Studies, 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 Reasoning question on Direction and Distance, write the sequence, code, or arrangement step by step and verify the pattern before finalising the answer.

The 2024 G20 Summit was held in Rio de Janeiro, Brazil. This is part of current events related to international summits. The G20 presidency rotates annually, and Brazil hosted it in 2024. Other options are incorrect: Johannesburg (South Africa) hosted in 2023, New Delhi (India) in 2023 (virtual) or other years, Rome (Italy) in 2021. Knowing recent hosts helps eliminate wrong choices.

Key point: understanding text manipulation in MS Word. To duplicate text without removing it, 'Copy' (C) creates a copy, and 'Paste' places it elsewhere. 'Cut' (D) removes the original text, which is not desired. 'Delete' and 'Undo' (A) or 'Move' (B) do not achieve duplication. So, option C is correct, aligning with standard MS Word procedures.

Given Q on Saturday, T and U have 4 people between them, not on Monday. Since R is before V and P is after V, and U is after P, the sequence from Monday is: R, V, P, U, T, [others], Q (Saturday). This places R on Monday, with 4 people (V, P, U, T) after R, not counting Q and the remaining person. So, 4 people have exams after R.
