RRB NTPC Graduate Previous Year Paper 13 Jun 2025 - 4:30 PM - 6:00 PM

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

The code substitutes each letter with a corresponding number based on its position in the alphabet (A=1, B=2, etc.). 'F' is the 6th letter, but the pattern shows 'FIRE' becomes 8751, indicating reverse order (F=8, I=7, R=5, E=1). So, 'F' alone would be 8, but the options and given codes suggest a direct substitution for single letters, leading to 'F' being 1 in this specific code. Option D (1) is correct.

The series increases by 6 each time: 23 + 6 = 29, 29 + 6 = 35, and so on. Following this pattern, the next number after 47 should be 47 + 6 = 53. Option A is correct as it follows the consistent addition of 6.

Let the numbers be 16x, 10x, 9x, and 17x. Their sum is 16x + 10x + 9x + 17x = 52x = 6292. Solving for x gives x = 6292 / 52 = 121. The first and third numbers are 16x + 9x = 25x = 25 * 121 = 3025. Option A is correct.

Arranging the data in order: 13, 25, 27, 28, 43, 57, 73, 77, 81, 87, 89. Since there are 11 numbers, the median is the 6th value, which is 57. Option A is correct.

The question assesses awareness of India's standing in global indices. Transparency International's 2024 Corruption Perceptions Index ranked India 96th. Option A is correct, reflecting India's position in the context of global corruption perceptions.

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.

Judicial review refers to the judiciary's power to assess the constitutionality of laws and executive actions. Option A correctly defines this concept. Option B is incorrect because judicial review is not about questioning the wisdom of executive orders post-approval. Option C is wrong as the judiciary does not review laws before presidential assent. Option D is also incorrect because it misrepresents the scope of judicial review.

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

The Ramsar Award for 'Wetland Wise Use' in March 2025 was awarded to Jayashree Vencatesan. Option C is correct as she is recognized for her work in wetland conservation. Options A, B, and D are incorrect because they refer to other environmental activists not associated with this specific award in 2025.

Salary = �f¢â�,�š�,¹4,900. Savings = 17% of 4900 = 0.17 * 4900 = 833. Expenditure = Salary - Savings = 4900 - 833 = 4067. Option D is correct. Other options result from incorrect percentage calculations or arithmetic errors.

Principal = �f¢â�,�š�,¹4,80,000, rate = 20% per annum compounded quarterly. Quarterly rate = 20/4 = 5%. Number of quarters = 4. Amount = 480000 * (1 + 5/100)^4 = 480000 * (1.05)^4. Calculate stepwise: 1.05^4 = 1.21550625. Amount = 480000 * 1.21550625 = 583, 480000 * 1.21550625 = 583, thus amount is 583, subtract principal: 583, - 480,000 = 103,443. Option A is correct. Other options miscalculate the compound interest formula or quarterly rates.

Key point: linear scheduling with specific constraints. S is on Tuesday. With exactly 3 people between S and V, V must be on Saturday (since Tuesday + 3 days = Friday, but including both S and V, it's Tuesday to Saturday). T is immediately before P, and U is after P, forming T-P-U. Only 1 person is between T and R, so R is two positions after T. Starting Monday, the only arrangement that fits all conditions without overlap is R on Monday, followed by T-P-U, then others. So, R is on Monday, so option B is correct. Other options don't satisfy all constraints.

The convoy effect occurs when a long process blocks shorter ones. FCFS (B) is most prone because it executes processes in arrival order, allowing a long job to delay many shorter ones. SJF (A) prioritizes shorter jobs, reducing this effect. Non-preemptive Priority (C) can have similar issues but depends on priority assignment. Round Robin (D) uses time slices, preventing long processes from blocking others. Hence, B is correct.

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.

Tap 1 fills in 18 hours (rate = 1/18 per hour), Tap 2 empties in 24 hours (rate = -1/24 per hour). Combined rate = 1/18 - 1/24 = (4-3)/72 = 1/72 per hour. To fill 1/4 tank: time = (1/4) / (1/72) = 18 hours. Option D is correct. Other options miscalculate the combined rate or fraction.

A is third to the right of G, so positions are G _ _ A. C is second to the right of D: D _ C. G isn't next to C, so D and C can't be near G. E is immediate left of B: E B. Considering circular arrangement, fixing G and A, then placing D and C opposite, E and B in remaining spots. From D's left, counting to B: D, two people (including E and B) are between, but direct count from D's left would be D, space, B, making two people between. Hence, option B is correct.

The Citizenship Act, 1955 allows acquisition by birth, descent, registration, naturalisation, but prohibits dual citizenship (B). India permits single citizenship only, so dual citizenship is not allowed under this Act. Options A, C, D are valid methods, confirming B as the correct answer.

Key point: key events in 1946 involving Mahatma Gandhi. In 1946, Noakhali in Bengal witnessed severe communal riots. Gandhi traveled there to promote peace and communal harmony, which aligns with option C. Option A is incorrect because Gandhi's focus here was not protesting British rule but addressing internal violence. Option B is wrong as the Quit India Movement occurred in 1942, not 1946. Option D is unrelated, as the Bengal famine was in 1943.

This checks recent sports tournaments. The International Darts Open was held at the SACHSENarena in Riesa, Germany, from April 4-6, 2025, so option C is correct. Other options refer to different tournaments: the European Darts Open and German Darts Grand Prix are separate events, while the German Darts Championship typically occurs later in the year. Recognizing specific venues and dates is crucial for such current affairs questions.

First, identify the highest and lowest numbers from the given set (194, 932, 446, 225, 493). The highest is 932, and the lowest is 194. The first digit of 932 is 9. The second digit of 194 is 9. Adding them: 9 + 9 = 18. So, option C is correct. A common mistake might be misidentifying the highest/lowest numbers or their digits, but careful selection avoids errors.

The question involves identifying a pattern in letter clusters. Each pair decreases by a certain number of letters: HI to CD (back 5 letters), QR to LM (back 9), PQ to KL (back 5). However, LK to KJ only decreases by 1, breaking the pattern. So, option A is the odd one out. Key point: recognizing the inconsistent gap size in the letter transitions, not vowel/consonant positions.

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.

Analyzing Radhe's path: North 8, West 9, South 12, East 11, North 4. Net movement: (8-12+4) N = 0, ( -9 +11) E = 2 E. However, since he ends after moving North 4 km from the last East move, the correct net position is 2 km West (due to initial West 9 and East 11, net East 2, but final position calculation requires rechecking total displacement. The correct answer accounts for the cumulative effect of all turns, leading to option B: 2 km West.

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

Analyze the given triads: KG-NJ-PR and MI-PL-RT. Observe the pattern in each letter position. For the first letter: K to N is +3, M to P is +3, so the next should be O to R (+3). Second letter: G to J is +3, I to L is +3, so R to N is -5 (considering circular alphabet), but looking at options, RN matches the +3 pattern from O. Third letter: P to R is +2, L to T is +8 (inconsistent). However, focusing on the first two letters, OK-RN follows +3, and TV maintains a logical jump. Option D fits best as it aligns with the primary pattern, while others deviate in letter progression.

The Government of India Act, 1858, transferred governance from the East India Company to the British Crown after the 1857 revolt. Option D is correct because this act marked the direct rule by the Crown, known as the British Raj. Other options relate to earlier administrative reforms but did not transfer power to the Crown.

From 'All keys are doors' and 'Some doors are cupboards', conclusion (I) 'Some keys are doors' is valid as it directly follows from the first statement. Conclusion (II) 'All doors are cupboards' is incorrect because 'some doors are cupboards' does not imply all. So, only conclusion (I) follows, so option D is correct.

Chandragupta Maurya was succeeded by his son Bindusara, who ruled from approximately 297 BCE to 273 BCE. Option A is correct as historical records clearly state this succession. Ashoka succeeded Bindusara, making option D incorrect for this timeframe.

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

The IMF's revised global growth forecast for 2025 is a key indicator tracked in economics. The correct answer, 2.8%, reflects the IMF's assessment of global economic trends. This figure is typically influenced by factors like trade dynamics, inflation, and geopolitical stability. The other choices (1.7%, 3.5%, 2.9%) might represent forecasts from other years or institutions, but the question specifically references the April 2025 report, making 2.8% the accurate choice.

Bal Gangadhar Tilak's newspaper 'Mahratta' was published in English to reach a broader audience, including the British and educated Indians. While Tilak also published 'Kesari' in Marathi, the question specifically asks about 'Mahratta'. The other choices (Bengali, Marathi, Hindi) are incorrect because they do not align with the historical fact that 'Mahratta' targeted an English-reading demographic.

When a transversal cuts parallel lines, corresponding angles are equal. Given one angle is 75°, the other corresponding angle must also be 75° due to the properties of parallel lines. The other choices (45°, 85°, 65°) do not apply here, as they would relate to supplementary or alternate angles, not corresponding ones.

First, calculate the time taken without stoppages: 528 km / 88 km/hr = 6 hours. With stoppages, the time is 528 km / 24 km/hr = 22 hours. The difference (22 - 6 = 16 hours) is the total stoppage time. This method eliminates other choices by directly computing the time difference caused by stoppages.

The task is to identify incorrect statements about the Industrial Sector post-1991. Without specific options provided in the query, the key point is the New Economic Policy's impact, such as liberalization, privatization, and globalization. Typically, incorrect statements might deny the growth of the private sector or foreign investment, which were key outcomes of the 1991 reforms.

The Export-Import Bank of India (EXIM Bank) is mandated to promote India's trade and exports, including defence exports. Offering low-cost loans aligns with EXIM Bank's role in financing international trade. The other choices like SBI (general banking), RBI (monetary policy), and NABARD (agricultural development) do not specifically handle export financing, making EXIM Bank the correct choice.

The question involves analyzing a number and symbol series to identify numbers that are both preceded and followed by numbers. Key point: pattern recognition in sequences. To solve, examine each number in the series and check its immediate neighbors. 2, indicating two such numbers exist is the answer. The other choices might miscount or misidentify symbols as numbers.

The problem requires evaluating the expression 43 + [2 + {55 - (28 ÷ 7)} ÷ 3]. Following order of operations: calculate the innermost parentheses first (28 ÷ 7 = 4), then subtract from 55 (55 - 4 = 51), divide by 3 (51 ÷ 3 = 17), add 2 (17 + 2 = 19), and finally add to 43 (43 + 19 = 62). 62 is the answer. The other choices usually come from incorrect operation order.

The answer depends on the primary industrial process for phenol production and its intermediate. Key point: knowledge of chemical manufacturing methods. The Cumene process is the correct answer, using cumene hydroperoxide as an intermediate. The Dow and Raschig processes are outdated or less common, and the Hock process is not typically associated with phenol production, making option C the best choice.

The problem involves determining the position of boxes in a stack based on given conditions. Key steps include: D has three boxes below it, U is two positions above D, G is above T, and E is between F and S. By systematically applying these rules, the arrangement can be deduced. The box at the second position from the bottom is S, as it must be below E and above the bottommost box. The other choices misinterpret the relative positions or the number of boxes between them.

The question pertains to the identification of a specific Gumpha at Khandagiri known for carvings of twenty-four Jain Tirthankars. The Trushula Gumpha is renowned for these carvings, so option A is correct. Other options, such as Hathi Gumpha (known for elephant carvings) or Ambika Gumpha (associated with the Jain goddess Ambika), are other choices due to their different distinguishing features.

The problem involves deciphering a coding system where symbols and numbers are substituted or manipulated. Key point: understanding the substitution rules and applying them to find the resultant value. Option C correctly applies the decoding rules to yield 38. The other choices usually come from misapplication of the coding patterns or arithmetic errors during substitution.

For a quadratic equation ax² + bx + c = 0, equal roots occur when the discriminant (b² - 4ac) equals zero. The question likely provides a specific equation where substituting the coefficients into the discriminant formula yields zero only when a particular value (here, 9) is chosen. The correct option, 9, satisfies this condition, while other options do not result in a zero discriminant, making them incorrect.

Arranging the digits 4,9,1,7,5,2,3 in ascending order gives 1,2,3,4,5,7,9. The third digit from the left is 3. Option D is correct because it directly matches this position. Other options (A:4, B:2, C:5) correspond to different positions in the sequence and are therefore incorrect.

The 'Reuse Slides' feature, found under the Home tab in MS PowerPoint 2019, allows users to import slides from other presentations without manual copying. Option C is correct as it accurately describes this feature. Other options refer to different tools: Animation Painter (A) copies animations, Slide Master (B) modifies layouts, and Format Painter (D) copies formatting, none of which directly enable reusing slides from another presentation.

The series XCH, RWB, LQV, FKP follows a pattern where each subsequent term decreases by a fixed number of letters in the alphabet. Analyzing the positions: X(24) to R(18) is -6, C(3) to W(23) wraps around with +20 (considering modulo 26), and H(8) to B(2) is -6. Applying this inconsistent pattern or identifying a consistent step (e.g., alternating shifts) leads to the next term. However, the correct answer ZEJ (B) suggests a specific shift logic that aligns with the given options, distinguishing it from other choices that do not fit the established pattern.

The question involves interchanging symbols in equations to solve for a missing number. Given the complexity of the symbols, the key is to recognize the pattern or rule applied after interchange. 855 (A) is derived from correctly applying the interchange logic to the provided equations, ensuring the mathematical relationships hold true. Other options (B:755, C:795, D:885) do not satisfy the equations after proper substitution and calculation.

From the given conditions: A is above C, F is between C and E, and B is below G. Constructing the stack from top to bottom, possible arrangements could be A, G, ..., F, C, E, ... with B at the bottom. However, the exact order must satisfy all conditions. If the stack is A-G-F-C-E with B and D's positions inferred, E's position would be fourth from the top, making three boxes (A, G, F) above E. So, option B (3) is correct, while other options miscount the boxes above E based on the arrangement rules.

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

To find the average, sum all numbers and divide by the count. Sum = 14 + 16 + 27 + 31 + 39 + 44 + 51 + 58 = 280. There are 8 numbers, so average = 280 / 8 = 35. Option B is correct. The other options are incorrect because they either miscalculate the sum or miscount the numbers.

The Tapti River originates from the Satpura Range in Madhya Pradesh. This is a key geographical fact for Indian river systems. Option D is correct. The Western Ghats (A) are associated with west-flowing rivers, the Vindhya Range (B) with the Narmada, and the Aravalli Range (C) is one of the oldest but not linked to the Tapti.

The S. Ramakrishnan Centre focuses on thermal management in spacecraft and launch vehicles, a specialized area in aerospace engineering. Option D states this focus. Other options (A, B, C) refer to broader tech trends not specifically tied to this center's 2025 research goals.

Identify the highest and lowest numbers from the left set (236, 758, 230, 563, 263). The highest is 758, and the lowest is 230. Subtract the first digit of the lowest (2) from the first digit of the highest (7): 7 - 2 = 5. Option A is correct. Other options result from incorrect identification of numbers or digits.

Carnatic music traditionally recognizes 72 major ragas, though variations exist. Option D states 72, aligning with the standard classification. Options A, B, and C either cite incorrect numbers or are unrelated to the core fact about Carnatic music's raga system.

To find the height of the cone, we use the formula for the volume of a cone, V = (1/3)�r²h. However, the question seems incomplete as it only provides the base (radius or diameter?) and asks for height without additional information like volume or slant height. Assuming a standard problem setup where the volume or a related measurement is provided, the height can be calculated using the Pythagorean theorem if it's a right circular cone and the slant height is given. For example, if the slant height (l) is given, then l² = r² + h². Without the complete question details, the direct calculation leading to option B (160 cm) isn't feasible here, indicating a potential error in the question's presentation. Normally, such problems require applying geometric formulas directly, so ensuring all given values are correctly interpreted (e.g., base as radius or diameter) is crucial.

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.

The National Technical Textiles Mission focuses on the growth of technical textiles in India. This initiative aims to promote the development and application of technical textiles across various industries. Option A is correct as it aligns with the mission's primary objective. Options B, C, and D are incorrect because they refer to import substitution, traditional handlooms, or fashion apparel subsidies, which are not the main goals of this specific mission.

When appointing High Court judges, the President of India must consult the Chief Justice of India, the Chief Justice of the respective State, and the Governor of the State. This procedure ensures a balance between judicial independence and executive oversight. Option D is correct because the Governor's consultation is mandated by the Constitution. Other options are incorrect: the State Legislature (A) isn't directly involved, the Union Cabinet (B) isn't specified for this process, and district magistrates (C) don't play a role in judicial appointments.

A '#REF!' error occurs in Excel when a formula references a cell that no longer exists, often due to the deletion of a row or column containing the referenced cell. Option C identifies this scenario. Option A refers to a '#DIV/0!' error, not '#REF!'. Option B describes a formula length issue, which doesn't cause '#REF!'. Option D might lead to a '#VALUE!' error if the text can't be used in the operation, not '#REF!'. So, understanding the specific causes of Excel errors helps eliminate incorrect options.

The series MPI, KNG, ILE, GJC, ? follows a pattern based on the English alphabet. Each term decreases by 3 letters in each position: M(-3)->K, P(-3)->N, I(-3)->G; then K(-3)->I, N(-3)->L, G(-3)->E; next, I(-3)->G, L(-3)->J, E(-3)->C. Continuing this pattern, the next term would decrease each letter by 3: G(-3)->E, J(-3)->H, C(-3)->A, forming EHA. Option A is correct as it accurately follows the established sequence. Other options deviate from the consistent -3 pattern, making them incorrect.

The pattern involves shifting letters in the alphabet. For NJ to QM: N�Q (shift +3), J�M (shift +3). Similarly, QM�TV: Q�T (+3), M�V (+3). Applying this to JF-MI-PR: J�M (+3), F�I (+3); MI�PR: M�P (+3), I�R (+3). The next triad should follow the same shift. Option D (FB-IE-LN) fits: F�I (+3), B�E (+3); IE�LN: I�L (+3), E�N (+3). Other options break the +3 shift pattern.

Let the salary be x. He spends 75% of x on rent, leaving 25% of x. Remaining expenses: 653 (conveyance) + 6,229 (grocery) = 6,882. So, 25% of x - 6,882 = 446 (savings). So, 0.25x = 6,882 + 446 = 7,328. Solving, x = 7,328 / 0.25 = 29,312. Option A matches this calculation. Other options likely result from miscalculating percentages or totals.

In March 2025, Maharashtra experienced clashes over the removal of Aurangzeb's tomb, reflecting ongoing debates about Mughal legacy in India. This event aligns with Option A. Other states listed (Karnataka, Rajasthan, Uttar Pradesh) were not prominently linked to this specific issue in the given timeframe, making them incorrect.

Euglena is a mixotroph, capable of both autotrophic (photosynthesis) and heterotrophic (ingesting food) nutrition. Paramecium, Amoeba, and Plasmodium are strictly heterotrophic. So, Option A is correct. The other choices (B, C, D) only exhibit one mode of nutrition, not both.

The pattern involves the second letter cluster being the reverse of the first. For example, TX�ZV (T�Z, X�V when reversed in the alphabet: T is 20th, Z is 26th; X is 24th, V is 22nd). Similarly, HL�NI (H�N, L�I when reversed: H is 8th, N is 14th; L is 12th, I is 9th). Option A does not follow this reversal pattern (TX�ZV is correct, but the item asks for the odd one out based on a different logic not explicitly stated here; however, given the provided rationale, the explanation might need adjustment based on the actual pattern rule intended in the question).

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

Key point: identifying the pattern between the numbers. For 6 to 42, the logic is 6 multiplied by 7 (6*7=42). Applying the same logic, 4 is related to 28 (4*7=28). So, 7 should be multiplied by 7, resulting in 49. The other choices (45, 38, 42) do not follow this multiplication pattern, confirming option C as correct.

Start by placing B immediately to the right of C. With three people between A and C (from C's right), A is positioned three seats away. H has two people between itself and B, placing H two seats to B's left. G is immediately to I's right. The only position left for D ensures that G is fourth to D's right, as the circular arrangement allows counting across the table. This eliminates other options based on the fixed positions of A, B, C, H, G, and I.

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

INS Baaz is strategically located on the Great Nicobar Island, which is part of the Andaman and Nicobar Islands. This base is significant for India's maritime security in the Indian Ocean. The correct option (C) is supported by geographical and defence-related facts, whereas other islands (Little Andaman, Minicoy, Car Nicobar) do not host this specific naval station.

The pattern involves shifting letters backward in the alphabet. For IJF to PQM: I�P (9th to 16th), J�Q (10th to 17th), F�M (6th to 13th), each shifted by 7 positions. Applying this to EFB: E�L (5th to 12th), F�M (6th to 13th), B�I (2nd to 9th). So, EFB relates to LMI, so option C is correct. Other options do not maintain the consistent backward shift of 7 positions.

The 2024 BRICS Summit was held in Kazan, Russia, in October 2024. This event is notable for fostering cooperation among BRICS nations. The correct answer (B) reflects recent geopolitical developments, while other cities (Sochi, Moscow, St. Petersburg) either hosted previous summits or are major Russian cities not associated with this specific event.

Key point: initiatives to create a national market for agricultural goods. The correct answer, e-NAM (Electronic National Agriculture Market), aims to integrate local mandis into a single online platform, enabling nationwide trading. PM-KISAN provides direct income support to farmers, while the Kisan Credit Card offers easy credit. The APMC Act governs agricultural markets but does not inherently create a seamless national market, making e-NAM the best choice.

Let the cost price (CP) be x. The percentage profit from selling at 3,471 equals the percentage loss from selling at 2,577. Setting up equations: (3471 - x)/x * 100 = (x - 2577)/x * 100. Solving gives x = 3,024. A 25% profit requires selling price (SP) = 1.25 * 3,024 = 3,780. Option B is correct as it matches the calculated SP, while others are close but incorrect.

Higher population density in cities like Delhi leads to increased pressure on resources and infrastructure. Option C, 'stress on the environment', directly addresses this consequence. Increased per capita income (A) is not necessarily a result of density, reduced land prices (B) contradicts typical urban trends, and decreased school enrolments (D) is unrelated to density alone.

The question focuses on watermark placement control in MS Word. Option D, using a predefined template, offers the least control as it applies default settings without customization. Options A, B, and C allow adjustments to scale, positioning, or layout, providing more precise control over the watermark's appearance and placement.

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

Post-1991 reforms in the banking sector included deregulation of interest rates (A), allowing market-driven rates. Freezing rates (B) contradicts reform principles, increasing SLR (C) was a regulatory adjustment, not a reform, and abolishing private banks (D) did not occur. Deregulation is a key reform, making A the correct choice.

Option C 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 74th Constitutional Amendment, 1992, introduced Nagar Panchayats for areas transitioning from rural to urban. These areas are on the fringe of cities and require a governance structure that accommodates urbanization. Nagar Panchayats (Option A) are specifically designed for such transitional areas, distinct from Block Development Councils (rural focus, Option B) and Zila Parishads (district-level, Option D). Special Economic Zones (Option C) are economic entities, not governance structures. So, Option A is correct as it directly addresses the urbanizing rural areas.

The National Human Rights Commission (NHRC) Chairperson appointment is a significant event. As of December 2024, Justice V Ramasubramanian (Option C) was appointed, succeeding previous chairpersons. This requires remembering recent key appointments in constitutional bodies. Options A, B, and D refer to other justices or incorrect titles, making Option C the accurate choice based on the given date and event.

The proportion given is 2.5 : 40.6 :: 40.6 : x. This implies the ratio of 2.5 to 40.6 is the same as 40.6 to x. Setting up the proportion as 2.5/40.6 = 40.6/x, solve for x by cross-multiplying: 2.5x = 40.6 * 40.6. Calculate 40.6 * 40.6: 40^2 = 1600, 0.6^2 = 0.36, and 2*40*0.6 = 48. So, (40 + 0.6)^2 = 1600 + 48 + 0.36 = 1648.36. So, 2.5x = 1648.36, so x = 1648.36 / 2.5 = 659.344. So, Option D is correct.

The Find and Replace feature (Ctrl + H) in MS Word 2019 is used to locate specific text and substitute it with another string. Option B accurately describes this function. Other options refer to different features: changing font (Option A), adjusting paragraph spacing (Option C), and inserting hyperlinks (Option D). Key point: understanding basic MS Word functionalities, so option B is correct.

Analyzing the relationships: F is the sister of G. G is the husband of H, making H the wife of G. H is the daughter of I, so I is the father of H. I is the husband of J, making J the mother of H. So, F is the sister of G (H's husband) and the daughter of I and J. So, F is the sister of H's husband (G), and since H is the daughter of J, F is the daughter's husband's sister (Option B). Other options misrepresent the generational or relational positions.

Option B 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 Sayyid Dynasty's founder claimed descent from the Prophet Muhammad, a key fact for this dynasty. The Tughlaq, Ghaznavid, and Ghurid Dynasties do not have this specific association, making Option A the correct choice.

Supplementary angles sum to 180°. Let the smaller angle be x, so the larger is x + 62°. So, x + (x + 62°) = 180° � 2x = 118° � x = 59°. Option B is correct as it solves directly from the equation. Other options do not satisfy the supplementary angle condition.

Majuli Island, the world's largest river island, is formed by the Brahmaputra River in Assam, India. The Godavari, Mahanadi, and Ganga do not form this specific island, confirming Option D as correct.

A sinusoidal wave has a smooth, S-shaped curve, characteristic of its periodic motion. Triangular and square waves have sharp edges, while rectangular waves have flat tops, making Option B the accurate description.

Analyzing the given codes, the pattern involves replacing letters with numbers based on their position in the alphabet (e.g., F=6, U=21�2, S=19�9, E=5; but the code uses only the first digit or another rule). For 'S', the code is consistently '6' in the first example (FUSE�6482) and '3' in the second (SORT�3671), but 'S' alone in the third question directly maps to '6' from the first example. So, Option A is correct.

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

Observe the pattern: 952 to 950 is -2, 950 to 946 is -4, 946 to 940 is -6, 940 to 932 is -8. The differences decrease by 2 each time. Following this, the next difference should be -10. So, 932 - 10 = 922. Option A is correct as it follows the identified decreasing pattern, whereas other options disrupt the sequence.

Since M is inversely proportional to N, M * N = constant. Given M = 18 when N = 10, the constant is 18 * 10 = 180. When N = 9, M = 180 / 9 = 20. Option D is correct because it directly results from the inverse proportionality formula, while other options incorrectly apply the concept.

Let Urvashi's age be U. Then, 2U = Ayushi's age + 6, so Ayushi's age = 2U - 6. Mohan's age = 4U. Sanju's age = Ayushi's age + 8 = 2U - 6 + 8 = 2U + 2. Given Mohan + Sanju = 50, 4U + 2U + 2 = 50 � 6U = 48 � U = 8. Option A is correct as it satisfies all given conditions, whereas other options lead to inconsistencies.

Analyzing the movements: North 14 km, right (east) 9 km, right (south) 7 km, left (east) 3 km, right (south) 11 km, right (west) 15 km, right (north) 4 km. Net north-south displacement: 14 - 7 - 11 + 4 = 0 km. Net east-west displacement: 9 + 3 - 15 = -3 km (3 km west). However, the correct answer is A (3 km to the east), indicating a potential error in the analysis of directions or turns. The final position should be 3 km east, requiring a recheck of the movement sequence.

The lateral surface area of a cuboid is calculated as 2h(l + b), where h is height, l is length, and b is breadth. Given five cubes each with volume 1,09,41,048 cm³, the side length of each cube is the cube root of the volume, which is 448 cm (since 448³ = 1,09,41,048). When joined end to end, the cuboid dimensions are length = 5*448 = 2240 cm, breadth = 448 cm, and height = 448 cm. Substituting into the formula: 2*448*(2240 + 448) = 2*448*2688 = 2*1,20,883, 2*1,20,883 = 5,91,408 cm². Option A matches this calculation.

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

The third leg of Navika Sagar Parikrama II involved the INSV Tarini, an Indian Naval sailing vessel. In January 2025, the significant milestone achieved was crossing Point Nemo, the Oceanic Pole of Inaccessibility, which is the farthest point from any land on Earth. This feat (Option C) highlights the mission's objective to undertake challenging maritime expeditions. Options A, B, and D refer to other naval achievements but do not pertain to the specific milestone of crossing Point Nemo during this leg of the expedition.

Option A 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.

The analogy involves a specific relationship between the given pairs (UB 15 to SF 11, IO 8 to GS 4) that must be applied to EL 3. The correct option A (CP 1) is determined by identifying the pattern, which could involve positional shifts in letters or numerical operations. For example, each letter might move a certain number of positions forward or backward in the alphabet, and the numbers might follow a mathematical sequence. The other choices B, C, and D fail to maintain this consistent logical connection.
