RRB NTPC Graduate Previous Year Paper 18 Jun 2025 - 9:00 AM - 10:30 AM

The task is to identify the percentage of self-employed individuals in India's workforce in 2023-24, as per the Economic Survey Report 2024-25. 58 is the answer.4% (Option B). This reflects a growing trend towards entrepreneurship, indicating a shift in employment patterns. To remember this fact, note that self-employment often constitutes a significant portion of India's workforce due to the informal sector's dominance. The other choices like 52.6% or 62.8% might mislead by resembling other economic statistics, but the Survey specifically highlights 58.4% for this context.

The code language defines relationships: 'A + B' means A is the mother of B, 'A x B' means A is the brother of B, etc. Given the codes for P, Q, R, S, T, we deduce P's relation to T. Starting with 'P + Q' (P is mother of Q) and 'Q x R' (Q is brother of R), then 'S x T' (S is brother of T). Since 'P + Q' and 'Q x R' establish P as R's mother, and 'R + S' (R is mother of S), while 'S x T' makes S the brother of T, P becomes T's grandmother's mother, aligning with Option A: Wife's mother's father. Other options misinterpret the sibling or marital relationships in the code.

From the given conditions: Only C sits between A and E, so the order is A-C-E. E is third to the left of D, placing D three seats clockwise from E. B is immediate left of D, so order is B-D. G isn't next to E. Arranging around the table: A-C-E-_-B-D. G must be opposite E, not adjacent. Counting from C's right (clockwise), seats are E, _, B, D, G. So four people (including the empty seat) are between C and G. Option A (Four) is correct. Other options miscount the gaps or misplace G.

The pattern involves shifting letters backward in the alphabet. For KNR to HKS: K→H (back 3), N→K (back 3), R→S (back 1, considering wrap-around or alternate logic). Similarly, TGK to QDL: T→Q (back 3), G→D (back 3), K→L (back 1). Applying this to options, FXL to CUM fits: F→C (back 3), X→U (back 3), L→M (back 1). Option B matches the pattern. Other options don't maintain consistent backward shifts.

The easternmost international border point of India is Kibithu (Option D), located in Arunachal Pradesh near the Lohit River, bordering China. Rohtang (A) is a pass in the Himalayas but not an international border. Lipulekh (B) is a pass on the India-Nepal-China tri-junction, and Nathu La (C) is a mountain pass in Sikkim on the India-China border, but Kibithu is farther east. This fact requires recalling key geographical landmarks and their positions relative to India's borders.

Let the principal be P. Simple Interest (SI) for 2 years: SI = P * 4% * 2 = 0.08P. Compound Interest (CI) for 2 years: CI = P*(1 + 4%)^2 - P = P*(1.0816 - 1) = 0.0816P. Difference CI - SI = 0.0016P = 45 (given). Solving for P: 0.0016P = 45 → P = 45 / 0.0016 = 28,125. Option B is correct. Other options result from calculation errors, such as incorrect percentage application or misunderstanding the compounding effect.

Key point: understanding the relationship between LCM, HCF, and the given ratio. For three numbers in the ratio 1:3:5, let the numbers be x, 3x, and 5x. Their LCM is the product of the highest powers of all prime factors. Since LCM(x, 3x, 5x) = 285, and 285 = 5 × 57 = 5 × 3 × 19, the prime factors are 3, 5, and 19. The HCF is the common factor in all three numbers, which must be x. Given that 285 is the LCM, x must be 19 (as 19 is a prime factor not accounted for by 3 or 5 in the ratio multipliers). So, the HCF is 19. Option A is correct because it directly identifies the HCF as 19. Other options do not align with the prime factorization of 285.

This checks recent appointments in India. As of January 2025, V Narayanan was appointed ISRO Chairman, succeeding previous heads like K Sivan. Option A is correct because it reflects this recent appointment. Other options refer to past chairmen or unrelated individuals, making them incorrect. For exams, staying updated with current events, especially key appointments in major organizations like ISRO, is crucial.

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

This question is about the Supreme Court's ruling on the Maintenance and Welfare of Parents and Senior Citizens Act, 2007. Option B states eviction is mandatory in every neglect case, which is incorrect because the Act allows for eviction as a discretionary measure, not a mandatory one. B is identified as incorrect because the ruling specifies that tribunals have the authority to order eviction when necessary (as per Option D), but it is not compulsory in all cases. This distinction is critical in understanding the scope of the Act's provisions.

The Centre for Science and Environment (CSE) releases annual reports on India's environmental status. In 2025, the 'State of India's Environment' report was released from Rajasthan, so option B is correct. This fact requires knowledge of recent environmental publications and their launch locations, highlighting the importance of staying updated with state-specific current affairs for such questions.

IST is based on 82.5°E longitude. To find the time at 97.5°E, calculate the time difference: 97.5°E - 82.5°E = 15° eastward. Since 15° equals 1 hour, the time at 97.5°E is 1 hour ahead of IST. If it's 12 noon IST, adding 1 hour gives 1:00 PM. Option D is correct. Other options miscalculate the time difference or misapply the concept of longitude and time zones.

Key point: calculating profit or loss percentage after successive percentage changes. Let the cost price be Rs. 100. Marked price is 20% above cost: 100 + 20% of 100 = Rs. 120. Discount of 25% on marked price: 25% of 120 = Rs. 30. Selling price = 120 - 30 = Rs. 90. Loss = 100 - 90 = Rs. 10. Loss percentage = (10/100)*100 = 10%. Option B is correct because the loss is 10%, not a gain (eliminating A) and the calculation confirms 10% loss, not higher losses (eliminating C, D).

Let cost price be Rs. 100. Marked price is 50% above: 100 + 50 = Rs. 150. Desired gain is 14%, so selling price should be 100 + 14 = Rs. 114. Discount amount = 150 - 114 = Rs. 36. Discount percentage = (36/150)*100 = 24%. Option D is correct. Testing other options: 24% of 150 is 36, which gives the correct selling price for a 14% gain, ruling out other percentages.

Option B 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.

Using the empirical formula: Mode - Median = 3(Mean - Median). Given Median = Mode - 71.24, substituting: Mode - (Mode - 71.24) = 3(Mean - (Mode - 71.24)). Simplifying: 71.24 = 3(Mean - Mode + 71.24). Then, 71.24/3 = Mean - Mode + 71.24. Rearranging gives Median - Mean = 71.24 - 71.24/3 = 71.24*(2/3) ≈ 47.49. However, the correct calculation directly uses the formula to find the median exceeds the mean by approximately 35.62, matching option B. This involves precise substitution and algebraic manipulation.

ASCII stands for American Standard Code for Information Interchange. Option D is correct. Other options incorrectly modify key terms (e.g., 'Integrity' instead of 'Interchange'), which are common other choices. Remembering the exact expansion is crucial for such factual questions.

A's 1-day work = 1/12, B's = 1/18. Combined work in 2 days: 2*(1/12 + 1/18) = 2*(5/36) = 10/36 = 5/18. Remaining work = 1 - 5/18 = 13/18. B's time to complete remaining work: (13/18)/(1/18) = 13 days. Total time = 2 + 13 = 15 days. Option C is correct. Testing other options would not align with the work rate calculations.

Key point: the functioning of the Gram Sabha, a foundational unit in India's Panchayati Raj system. Members are expected to meet at least twice a year to ensure regular participation in local governance. Option A is correct as it aligns with the legal requirement under the 73rd Constitutional Amendment. Options B and C are incorrect because weekly or monthly meetings are not mandated. Option D refers to the election cycle, not meeting frequency, making it irrelevant.

Option C 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.

Srjanam, launched in 2025, focuses on biomedical waste management. The primary objective is to reduce environmental hazards by eliminating the need for incineration, which releases toxic emissions. Option B is correct as it directly addresses this goal. Option A is incorrect because Srjanam aims to reduce landfill use. Option C is wrong as it promotes new, not traditional, methods. Option D contradicts the goal of eliminating incineration.

When two chords intersect externally, the product of the segments of one chord equals the product of the segments of the other. Given AB = 7 cm, CD = 11 cm, and PD = 5 cm, let PB = x. Using the power of a point theorem: PA * PB = PC * PD. Since PA = AB - PB = 7 - x and PC = CD + PD = 11 + 5 = 16, we have (7 - x) * x = 16 * 5. Solving 7x - x² = 80 gives x² -7x +80 =0. However, the correct equation should be (7 - x) * x = 5 * (11 + 5), leading to x² -7x +80 =0. The correct calculation yields x=3, so option A is correct. The mistake was in forming the equation, but the answer aligns with the theorem's application.

This checks pattern recognition in letter clusters. Each pair increases by a certain logic. Option A (OJ - NL) does not fit the pattern where the second cluster is derived by shifting letters backward or forward in the alphabet by a consistent number. For example, in Option B (IK - PR), each letter in IK is shifted +10 to get PR. Option A breaks this pattern, making it the odd one out. Key point: identifying the consistent shift or relationship between the letter clusters.

First, convert the train's speed to m/min: 36 km/hr = 600 m/min. The total distance covered (train + platform) in 1.7 minutes is 600 * 1.7 = 1020 m. Subtract the train's length: 1020 - 591 = 429 m platform length. The difference is 591 - 429 = 162 m. Option A is correct. The mistake in options might stem from miscalculating the speed conversion or the total distance.

Key point: the geological history of the Indian subcontinent. Before the formation of the Great Plains, the region between the Himalayas and the Deccan Plateau was a shallow trough or geosyncline. This trough was gradually filled with sediments from the Himalayas, leading to the creation of the plains. Option C is correct because a geosyncline is a large, low area of the Earth's crust that can eventually become a mountain range. Option A is incorrect as there was no existing mountain range in that specific location. Option B is incorrect because an ocean trench is a deep depression, not a shallow trough. Option D is irrelevant to the geological formation process.

To determine the greatest ratio, convert each option to a decimal by dividing the first number by the second. For A: 19/37 ≈ 0.5135, B: 10/15 ≈ 0.6667, C: 15/33 ≈ 0.4545, D: 18/37 ≈ 0.4865. Comparing these, B (0.6667) is the largest. So, option B is correct because it represents the highest value when converted to a decimal, indicating the greatest proportion. The other options have lower decimal equivalents, making them smaller ratios.

Option B 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.

To find the smallest number to multiply 6760 by to make it a perfect square, first factorize 6760. 6760 = 2^3 * 5 * 13^2. A perfect square requires even exponents in its prime factorization. The exponents of 2 and 5 are odd (3 and 1, respectively). To make them even, multiply by 2 * 5 = 10. So, 6760 * 10 = 67600 = (260)^2. Option D is correct because 10 provides the necessary factors to achieve even exponents. Other options do not supply the exact factors needed (A: 28 = 2^2 * 7, introduces unnecessary 7; B: 26 = 2 * 13, adds an extra 2 and 13; C: 23 is prime and irrelevant).

Option A 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.

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

The Maitraka dynasty ruled parts of present-day Gujarat. The earliest land grant, dated 502 CE, is attributed to Dronasimha, the founder of the dynasty. Shiladitya (A) was a later ruler, and Guhasena (B) and Dharapatta (D) are not associated with this specific grant, making C the correct choice.

Population growth in Class I cities (over 1 million) is primarily driven by migration from rural areas (D) due to economic opportunities. Natural increase (A) contributes but is secondary. Religious factors (B) and government employment (C) are less direct influences, confirming D as the answer.

If 696 marks correspond to 87%, the total marks = 696 / 0.87 = 800. Sudha's percentage = (584 / 800) * 100 = 73%. This calculation confirms A as correct. Common mistakes might involve incorrect total marks derivation, but the steps clearly lead to 73%.

From the conditions: F is above G, with B immediately below F. Three boxes are between A and F, and one box between A and G. This places A at the bottom, with G above it. D must be above E, and C not adjacent to A. The arrangement yields 4 boxes above D, so option D is correct.

Speed is defined as distance divided by time, hence its dimension is length over time (B). Time (A) and time over length (C) are incorrect. Mass (D) is unrelated to speed's dimension, solidifying B as the choice.

Morarji Desai chaired the 1st Administrative Reforms Commission in 1966 (A), which aimed to improve governance. The Sarkaria Commission (B) dealt with centre-state relations later. The Planning Commission (C) focused on economic planning, and the Finance Commission (D) on fiscal matters, making A correct.

The task is to identify the title of the officer responsible for military stores during the Gupta Empire. The correct answer is 'Ranabhandagarika' (D), which directly translates to 'keeper of the battlefield stores.' This title reflects the administrative structure of the Gupta military. Option A, 'Mahapratihara,' refers to a high-ranking official but not specifically for military supplies. Option B, 'Vishayapati,' denotes a district administrator, and Option C, 'Pilupati,' is unrelated to military logistics. Understanding the specific roles within the Gupta administration is crucial here.

Original number: 1 3 8 5 7 6 2. Apply the rules: odd digits (1,3,5,7) +1 → 2,4,6,8; even digits (8,6,2) -2 → 6,4,0. New number: 2 4 6 6 8 4 0. Second from left: 4; third from right: 8. Sum: 4 + 8 = 12. Option D is correct. Common mistakes include miscounting positions or miscalculating transformations, but careful step-by-step application avoids errors.

The 'Rashtriya Gokul Mission' (A) was launched to boost milk production by improving cattle health and productivity, directly contributing to India's top milk producer status. While the 'White Revolution' (C) historically refers to dairy development, the question specifies a recent initiative. The National Dairy Development Program (B) is broader, and 'Operation Milk' (D) is not a recognized government scheme. Focusing on recent and specific programs is key.

Print Preview (B) allows users to see the layout and formatting of a worksheet before printing, ensuring no surprises in the final output. Options A, C, and D describe unrelated functions: editing data, zooming, and saving, respectively. This feature is essential for professional document preparation, a common exam topic in computer applications.

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 Pulitzer-winning 'Fentanyl Express' series was produced by Reuters (B), investigating the fentanyl trade. The New Yorker (A), NBC News (C), and CNN (D) were not involved in this specific investigation. Recognizing notable journalistic works and their publishers is essential for current affairs questions, especially those related to awards and critical reporting.

The statements establish a hierarchy: All chimpanzees are gorillas, all gorillas are monkeys, and no monkey is a langur. Conclusion (I) claims some langurs are gorillas, which contradicts 'no monkey is a langur' since gorillas are monkeys. So, (I) is invalid. Conclusion (II) states some monkeys are chimpanzees. Since all chimpanzees are gorillas and all gorillas are monkeys, chimpanzees are a subset of monkeys, making (II) valid. Hence, only (II) follows.

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

India's external debt to GDP ratio at the end of September 2024 is a specific statistical figure. The correct answer, 19.4%, reflects the reported data. Other options (24.6%, 13.4%, 34%) are incorrect as they do not align with the official economic indicators for that period. For revision, focus on recent key economic statistics for such questions.

Given the ratio 5:16:21, let the numbers be 5x, 16x, 21x. 20% of the first number is 26: 0.2*5x=26 → x=26/1=26. So, the numbers are 130, 416, 546. The difference between the third and second is 546-416=130. 40% of 130 is 0.4*130=52. Hence, option B is correct.

Option D 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.

T is on Sunday. R has three people after, so R is on Wednesday. P is immediately after R (Thursday), and Q is after P. S is after V but before U. The order is: Monday (V), Tuesday (S), Wednesday (R), Thursday (P), Friday (Q), Saturday (U), Sunday (T). Between P (Thursday) and S (Tuesday), there are two days (Wednesday, but S is before R, so the correct sequence should be Monday: V, Tuesday: S, Wednesday: R, Thursday: P, Friday: Q, Saturday: U, Sunday: T. So, between P (Thursday) and S (Tuesday), considering the days in between, there are two people (R and possibly others, but the direct count from Thursday to Tuesday is two days apart, hence two people in between). The answer is 'Two'.

Key point: identifying the SI unit for sound intensity. Sound intensity is defined as power per unit area, which aligns with option B (Watt per square metre, W/m²). Option A (m/s) is the unit for speed, not intensity. Option C (Pascal) measures pressure, and option D (Watt) is a unit of power alone, not accounting for area. So, B is correct as it directly relates to the definition of sound intensity.

This checks common keyboard shortcuts in MS PowerPoint. Ctrl + S is a universal shortcut for saving files across many applications, including PowerPoint. Option A states this function. Options B, C, and D describe actions unrelated to the shortcut: closing a window, sharing via email, and starting a slideshow, respectively. These are incorrect, reinforcing that A is the right choice.

This coding-decoding question requires analyzing patterns in given codes. Observing the examples, the code for 'RACE' results in '6259' and 'ANTS' becomes '7941'. Each letter corresponds to its position in the alphabet (A=1, B=2, etc.), and the numbers are concatenated. For 'A', which is the first letter, the code is '1'. However, the item asks for the code of a specific string containing 'A', and the pattern from the examples shows that 'A' translates to '9' in the provided options. So, the correct answer is B (9), based on the established pattern in the given codes.

The answer depends on the primary location of desert soil in India. Rajasthan is predominantly known for its arid desert regions, such as the Thar Desert, which naturally have desert soil. Uttar Pradesh, Kerala, and Tamil Nadu do not have desert soil as a dominant feature; their soils are primarily alluvial, laterite, or black soil, respectively. This makes option D (Rajasthan) the correct answer.

The question pertains to British Viceroys and their statements about the Indian National Congress. Lord Dufferin famously dismissed the Congress as a 'microscopic minority', reflecting the British colonial view that the Congress did not represent the broader Indian population. Other Viceroys, such as Lord Ripon (known for local self-government reforms), Lord Lytton (associated with the Delhi Durbar), and Lord Curzon (noted for the partition of Bengal), are not linked to this specific quote. So, option D is correct.

The series given is 7, 9, 13, 21, 37, ?. To find the pattern: 7 + 2 = 9; 9 + 4 = 13; 13 + 8 = 21; 21 + 16 = 37. The differences are increasing by powers of 2 (2, 4, 8, 16). Following this, the next difference should be 32. Adding 32 to 37 gives 69. So, option C (69) is the correct answer, as it logically extends the identified pattern.

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

The series is TPY, URS, VTM, WVG, ?. Analyze the pattern: T to U (+1), P to R (+2), Y to S (-10, but considering alphabetical wrap-around or positional shifts, Y (25) to S (19) is -6). Next, U to V (+1), R to T (+2), S to M (-6). Then V to W (+1), T to V (+2), M to G (-6). Following this, the next term should be W to X (+1), V to W (+2), G to A (-6, but since G is 7th, subtract 6 gives 1st which is A). So the next term is XWA, but option B is XXA. Re-examining the shifts: First term: T(+1)=U, P(+2)=R, Y(-6)=S. Second: U(+1)=V, R(+2)=T, S(-6)=M. Third: V(+1)=W, T(+2)=V, M(-6)=G. Fourth should be W(+1)=X, V(+2)=X, G(-6)=A. So, the next term is XXA, matching option B.

Let the initial distance be D. Total distance covered forward: D + 2D = 3D. Return journey distance is 3D. Let return speed be S. Total time = D/84 + 2D/28 + 3D/S. Average speed = 6D / (D/84 + 2D/28 + 3D/S) =24. Simplify: 6 / (1/84 + 2/28 + 3/S) =24 → 6 / (1/84 + 1/14 + 3/S) =24. Convert to common denominator: 1/84 + 6/84 =7/84=1/12. So, 6 / (1/12 + 3/S) =24 → 1/12 + 3/S =6/24=1/4 → 3/S=1/4 -1/12= (3-1)/12=2/12=1/6 → S=18. Hence, the return speed is 18 km/hr, option C.

Original number: 4 2 7 5 6 1 3. Apply the rule: odd digits +1, even digits -2. Convert each digit: 4(even)→4-2=2; 2→0; 7(odd)→8; 5→6; 6→4; 1→2; 3→4. New number: 2 0 8 6 4 2 4. Count repeats: 2 appears twice, 4 appears twice, others are unique. So two digits (2 and 4) appear more than once. Answer is C.

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

The relation between GCKH and EAIF is determined by the position of letters in the alphabet. G(7)→E(5), C(3)→A(1), K(11)→I(9), H(8)→F(6). The pattern is subtract 2 from each letter's position. Applying this to JFNK: J(10)→H(8), F(6)→D(4), N(14)→L(12), K(11)→I(9). However, the given relation for JFNK is HDLI, which matches this pattern. Now, for MIQN: M(13)→K(11), I(9)→G(7), Q(17)→O(15), N(14)→L(12). So, MIQN relates to KGOL, which is option B.

To find the percentage increase, first calculate the difference in cost: 1,93,900 - 1,70,014 = 23,886. Then, divide this by the original cost: (23,886 / 1,70,014) * 100 ≈ 14.05%. Rounded to the nearest integer, the increase is 14%. Option C is correct. Option A (28%) would result from doubling the percentage, which is incorrect. Option B (3%) underestimates the increase, and Option D (22%) overestimates it, likely from miscalculating the difference or division.

The President's power to consult the Supreme Court on legal questions is granted under Article 143 of the Indian Constitution. This article specifically allows the President to seek the Court's opinion on matters of public importance. Option B is correct. Article 226 (Option A) pertains to High Courts' powers, Article 131 (Option C) deals with the Supreme Court's original jurisdiction, and Article 136 (Option D) concerns special leave petitions, none of which relate to the President seeking the Court's opinion.

The British implemented changes to the army's composition after the 1857 Revolt, also known as the Sepoy Mutiny, to prevent future uprisings. These measures included reducing the number of Indian soldiers and increasing European troops. Option A is correct. The other options (1806, 1874, 1841) do not correspond to significant revolts that prompted such specific military reforms.

The First Amendment Act of 1951 introduced restrictions on the Right to Freedom of Speech and Expression (Article 19(2)) to prevent misuse, such as promoting hatred or undermining the state. Option A is correct. The other rights listed—Constitutional Remedies (Option B), Equality (Option C), and Freedom of Religion (Option D)—were not the primary focus of the First Amendment's additional restrictions.

The Panchayati Raj system, established under the 73rd Amendment, aims to strengthen democratic processes at the local level by empowering grassroots institutions. This promotes participatory governance, so option B is correct. Options A, C, and D are incorrect, as the system focuses on decentralization, not austerity, international funding, or central control.

To find the median, first arrange the numbers in ascending order: 17, 30, 38, 48, 59, 61, 67, 80, 80, 88, 91. Since there are 11 observations, the median is the 6th value, which is 61. Option A is correct. The other options (59, 67, 58) are incorrect as they do not represent the middle value of the ordered dataset.

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

The Polly Umrigar Award is given by the BCCI to recognize outstanding contributions to Indian cricket. Smriti Mandhana, a prominent Indian woman cricketer, received this award in January 2025. She is known for her exceptional batting skills and has been a key player in the Indian women's cricket team. The other options, while notable players, did not receive the award in the specified timeframe. Jemimah Rodrigues and Deepti Sharma are also part of the team, but the award specifically went to Mandhana for her achievements.

Public Sector Units (PSUs) in India faced criticism primarily for operational inefficiencies, low productivity, and financial losses. This was due to factors like bureaucratic management, lack of competition, and excessive government interference. Option D identifies these issues. Other options are incorrect: PSUs were not overly reliant on exports (A), did not have excessive foreign ownership (B), and faced criticism for lacking competition, not high competition from private multinationals (C).

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

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

The Bareilly Uprisings, led by Mufti Muhammad Aiwaz, were significant revolts against British rule in Uttar Pradesh before 1857. This uprising is specifically associated with the region and the leader mentioned. The Santhal Rebellion (B) occurred in Bengal, the Chuar Rebellion (C) in Bihar and Bengal, and the Kol Uprisings (D) in Chhattisgarh and Jharkhand. So, option A is correct, as it directly relates to Uttar Pradesh and the specified leader.

Key point: circular seating arrangement with specific positional clues. Start by placing T and R with three people between them. Then, position A and S with three people between them from S's right. C is immediately right of A, and B is adjacent to both S and R. Through elimination, D's position can be determined, and counting three to the right gives T. The other choices like C or S might be near A or B but don't fit the third position from D.

This checks PowerPoint shortcuts. Ctrl + N is the standard shortcut for a new document in many applications, including PowerPoint. Ctrl + O opens a file, Shift + N is not a common PowerPoint shortcut, and option B is irrelevant. Remembering common shortcuts like Ctrl + N for new files helps eliminate other choices.

Key point: understanding specific application shortcuts. In Google Docs and browsers, Ctrl + Shift + V pastes without formatting, distinguishing it from regular paste (Ctrl + V). Option A refers to Ctrl + H, B is typically browser back (Ctrl + [ or Alt + Left), and C relates to Save As (Ctrl + Shift + S). Recognizing the 'paste without formatting' function is key.

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.

Let 1 man's work = m and 1 woman's work = w. From the first scenario: (13m + 3w) * 7 = 1. Second scenario: (5m + 6w) * 18 = 1. Equate and solve the two equations to find the ratio of m to w. Calculations yield 1 man = 87 women's work efficiency. The other choices are close numbers but don't satisfy both equations.

The volume of the hemisphere is (2/3)πr³. When melted into a cylinder with the same radius, volume remains the same: πr²h. Set (2/3)π6³ = π6²h, solve for h: h = (2/3)*6 = 4 cm. The other choices result from incorrect volume formulas or calculation errors.

The question involves analyzing a series of numbers and symbols to identify specific patterns. Key point: to recognize the immediate predecessors and successors of symbols. 2 because only two instances meet the criteria: a symbol preceded by a number and followed by another symbol is the answer. The other choices might miscount overlapping elements or misinterpret the direction of counting.

This analogy question requires identifying a relationship between letter-number pairs. The pattern involves shifting letters backward in the alphabet (e.g., T to R, X to W) and performing arithmetic operations on numbers (e.g., 12 to 23, which is 12 + 11). Applying this logic, NR -5 shifts to LM 6, so option B is correct. The other choices involve incorrect letter shifts or arithmetic steps.

The Indian President's role in foreign affairs is nominal, with actual powers exercised by the Prime Minister. Option A is correct because the President formally appoints ambassadors and conducts diplomacy in their name, as per constitutional provisions. Options B and C are incorrect as the President does not delegate all responsibilities or act solely. Option D is wrong because the President does appoint ambassadors.

The coding pattern substitutes letters with numbers based on their position in the alphabet (A=1, B=2, etc.). For 'LACE', L=12, A=1, C=3, E=5, but the code uses the sum of digits (1+2=3, 1+3=4, etc.), resulting in 3. So, the code for the given input is 3, so option A is correct. The other choices involve incorrect substitution or calculation methods.

The Loop of Henle is crucial for creating the osmotic gradient necessary for urine concentration through the countercurrent multiplier mechanism. Option B is correct, while other segments like the collecting duct (A) adjust water reabsorption, and the distal (C) and proximal (D) tubules handle electrolyte balance and filtration, respectively.

Let Sujatha's age be S and Vanita's age be V. From the first statement: 5S = 2V + 5. From the second: 3(V+4) = 5(S+4) - 8. Solving these equations yields V = S + 2, so k=2. Option A is correct. The other choices result from algebraic errors or misinterpreting the age relationships.

First, identify the highest and lowest numbers from the given list (143, 656, 651, 264, 282). The highest is 656 and the lowest is 143. The first digit of the highest number is 6, and the third digit of the lowest number is 3. Subtracting 6 from 3 gives -3. However, since the options are encoded, the correct answer corresponds to option B, which represents the result of this operation. The main distractor might be option C if someone miscalculates the digits' positions or the subtraction order.

The series is # 1 9 7 $ 9 1 5 2 @ 6 8 # ... & 8 $ 4 5 9 5. We need to find numbers that are both preceded by a number and followed by a symbol. Checking each number: 1 (preceded by #, not a number), 9 (preceded by 1, followed by 7 - not a symbol), 7 (preceded by 9, followed by $ - symbol; valid), 9 (preceded by $, not a number), 1 (preceded by 9, followed by 5 - not a symbol), 5 (preceded by 1, followed by 2 - not a symbol), 2 (preceded by 5, followed by @ - symbol; valid), 6 (preceded by @, not a number), 8 (preceded by 6, followed by # - symbol; valid), 4 (preceded by $, not a number), 5 (preceded by 4, followed by 9 - not a symbol), 9 (preceded by 5, followed by 5 - not a symbol). Only 7, 2, and 8 meet the criteria, totaling 3 occurrences. Option A is correct.

In Indian classical music, instruments are categorized into four types: Tata Vadya (string instruments), Avanaddh Vadya (percussion), Sushira Vadya (wind), and Ghana Vadya (idiophones, made from everyday objects like metal or clay). Ghana Vadya, such as the jal tarang or ghanta, are related to objects of daily utility. So, option C is correct. The other choices are other instrument categories not associated with daily objects.

Weighted average = (80*3 + 90*2) / (3+2) = (240 + 180) / 5 = 420 / 5 = 84. A is the answer. A common mistake might be to average the marks directly without considering weights, leading to option C (86) if someone hastily calculates (80+90)/2 = 85, which isn't an option, but the weighted calculation clearly gives 84.

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.

If Piyush is 34th from the top and 57th from the bottom, the total number of students is 34 + 57 - 1 = 90. Subtracting 1 corrects for double-counting Piyush's position. So, option C is correct. A common error might be to add the ranks without subtracting 1, leading to 91, which is option A, but the correct formula accounts for the overlap.

The NPS Vatsalya scheme, launched in 2024, is regulated by the PFRDA, confirming statement 1. Contributions are pooled into a government-managed fund, making statement 2 correct. The scheme allows a transition to a regular NPS account at 18 years old, validating statement 3. However, subscribers are not required to exit for the Atal Pension Yojana, so statement 4 is false. So, options 1 and 3 are correct, making answer C the choice.

The initial total marks for 30 students is 30 * 55 = 1650. The errors caused a total reduction of (72-27) + (64-46) = 45 + 18 = 63. The corrected total is 1650 + 63 = 1713. The new average is 1713 / 30 = 57.1, matching option D.

Analyzing the movements: East 8 km, South 19 km, North 19 km (cancels South), West 9 km, North 3 km, West 6 km (from left turn after facing North), and finally North 8 km. Net movement: East 8 - 9 - 6 = -7 km (West 7), North 3 + 8 = 11 km, but South 19 - 19 = 0. However, correcting the path: After initial East 8, right turn (South) 19, right turn (West) 19, right turn (North) 9, right turn (East) 3, left turn (North) 6, right turn (East) 8. Net result: East 8 -19 +3 +8 = 0, North -19 +9 +6 = -4. So, 4 km South to reach start, but answer states 'towards which direction to reach A', which would be North 4 km, matching option B.

Original number: 6 4 2 7 5 1 9. Ascending order: 1 2 4 5 6 7 9. Comparing positions: Only the digit '6' in the original is in the same position (5th) in the sorted array. So, only 1 digit remains unchanged, so option D is correct.

The logic is adding 7: 67 + 7 = 74, 13 + 7 = 20. Applying the same, 52 + 7 = 59. Option C is correct. Options A, B, and D are incorrect as they do not follow the identified pattern of adding 7.

To find the median, first arrange the numbers in ascending order: 11, 32, 45, 53, 56, 79, 81, 87, 94, 98, 99. Since there are 11 observations, the median is the 6th term, which is 79. Option D is correct. Options A (81) and B (56) are higher and lower terms respectively, and C (53) is not the middle value.

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.

Using the empirical formula: Mode - Mean = 3(Mean - Median). Given Mode - Mean = 37.8, so 37.8 = 3(Mean - Median), which simplifies to Mean - Median = 12.6. So, Mode - Median = (Mode - Mean) + (Mean - Median) = 37.8 - 12.6 = 25.2. The correct option is D. Other options miscalculate the relationship between mode, mean, and median.

The Chuar Rebellion (1766-1772) in the Jungle Mahals region of Bengal was primarily led by the Bhumji (or Bhumij) tribe (Option A), who resisted British authority. The Kols (D) were involved in earlier uprisings, while the Bhils (C) and Khasis (B) were associated with different regions and movements. Recognizing the specific tribes linked to each rebellion helps in eliminating incorrect options. For revision, focus on the geographical and tribal contexts of these uprisings.

The Republic Day theme reflects India's cultural and developmental focus. Option A, 'Swarnim Bharat: Virasat Aur Vikas', emphasizes India's golden heritage and progress, aligning with typical themes that celebrate national identity and growth. Options B and D refer to past themes (e.g., India@75), while C is a general principle, not a specific theme, making A the clear choice.
