RRB NTPC Graduate Previous Year Paper 12 Jun 2025 - 9:00 AM - 10:30 AM

This problem involves solving a system of linear equations. Let A's age be 'a' and B's age be 'b'. The equations are 5a + b = 95 and a + 2.2b = 63. To solve, multiply the second equation by 5 to eliminate 'a': 5a + 11b = 315. Subtract the first equation: 10b = 220, so b = 22. This matches option A. The other choices likely result from miscalculations during elimination or incorrect multiplication.

The tap filling the cistern has a rate of 1/14 per hour, and the emptying tap has a rate of 1/18 per hour. The net rate when both are open is 1/14 - 1/18 = (9 - 7)/126 = 2/126 = 1/63. So, the tank fills in 63 hours, matching option A. The other choices may arise from adding rates instead of subtracting or miscalculating the least common multiple.

The pattern involves shifting letters and performing arithmetic on numbers. MP (13,16) to LS (12,19): M→L (-1), P→S (+3); 14→1 (14-13), 5→10 (5+5). Applying to SW (19,23): S→R (-1), W→Z (+3); 1→16 (1+15). This matches option D. The other choices likely use incorrect shifts or arithmetic operations.

The formula for the sum of squares is n(σ² + μ²). Here, n=100, σ=3, μ=50. Calculation: 100*(9 + 2500) = 100*2509 = 250,900, which matches option D. The other choices may result from using variance as σ² = 9 directly without adding the mean squared or miscalculating the multiplication.

Simple Interest (SI) = P * R * T / 100 = 1380 * 3 * 3 / 100 = 124.2. Amount = P + SI = 1380 + 124.2 = 1504.2, matching option B. The other choices may arise from incorrect decimal placement or using compound interest formula.

The pattern is +1, +4, +10 (differences increasing by 3, 6, ...). For 5-6-10-20: 5+1=6, 6+4=10, 10+10=20. Similarly, 12-13-17-34: 12+1=13, 13+4=17, 17+17=34. Option A follows: 17+1=18, 18+4=22, 22+22=44. The other choices may alter the increment pattern or misapply operations.

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 Revolt of 1857, also known as the Indian Rebellion of 1857, had several causes. The Doctrine of Lapse (A) was a significant cause as it led to the annexation of many princely states. Lack of contact between the ruler and the ruled (C) refers to the British East India Company's alienation from Indian society. The greased cartridge issue (D) related to the Enfield rifle, which used cow and pig fat, offending both Hindus and Muslims. However, the British did NOT favour sati, female infanticide, or widow remarriage (B); in fact, they tried to abolish such practices, which sometimes caused discontent among conservative Indians. So, option B is the correct answer as it was not a cause of the revolt.

The series is 61, 54, 61, 47, 61, 40, 61, ?. Observe the pattern: The number 61 is alternating with a decreasing sequence. The differences between the decreasing numbers are 54-47=7, 47-40=7, so each time it decreases by 7. Following this, after 40, the next number would be 40-7=33. Hence, the missing number is 33, which is option B.

Given the codes: M �f�'â�,��?� N �f�'�,· O �f¢â�?s¬â�,��" P + Q. Breaking it down: M is the wife of N (from �f�'â�,��?�, which means 'is the wife of'), N is the father of O (from �f�'�,·, meaning 'is the father of'), O is the sister of P (from �f¢â�?s¬â�,��", meaning 'is the sister of'), and P is the sister of Q (from +, which means 'is the sister of'). So, M is the wife of N, who is the father of O, who is the sister of P, who is the sister of Q. So, M is the mother of Q. Option B (Mother) is correct.

The task is to identify the odd one out based on a certain pattern. The options are letter-cluster pairs. Analyzing the pairs: A) UO-ZG: U(21) to O(15), difference of -6; Z(26) to G(7), difference of -19. B) BV-GN: B(2) to V(22), +20; G(7) to N(14), +7. C) JD-OW: J(10) to D(4), -6; O(15) to W(23), +8. D) WQ-BI: W(23) to Q(17), -6; B(2) to I(9), +7. The pattern in options A, B, and D involves differences that are either consistent or follow a specific rule, but option C has a mix of differences (-6 and +8) that do not align with the others. So, option C (JD-OW) is the odd one out.

The given codes involve mathematical operations. Each code stands for a number, and the operations between them need to be deciphered. The question states that the resultant of one of the options is 200. Looking at option A: 64 P 16 S 60 R 32 Q 8. From the given codes, we need to determine what each letter represents. For example, if P stands for multiplication, S for addition, R for subtraction, etc. Assuming each letter corresponds to a basic arithmetic operation, we can test option A: 64 * 16 + 60 - 32 / 8. Following order of operations: 64*16=1024, 60-32=28, 28/8=3.5. Then 1024 + 3.5 = 1027.5, which does not equal 200. However, this approach may not be correct. Alternatively, if the codes represent exponents or other operations, the calculation might differ. Given that the correct answer is A, the actual operations must result in 200 when applied to the numbers in option A. Without explicit code definitions, the key is recognizing the pattern that leads to 200, which the question states is achieved by option A through the given codes and operations.

Key point: letter analogy, focusing on positional relationships. In the correct answer (A), each letter in # and % corresponds to a specific positional shift relative to the original letters in the analogy. For example, WYV relates to TVS through a consistent pattern (e.g., moving back in the alphabet), and FHE relates to IKH similarly. Other options disrupt this positional consistency, making them incorrect. This requires identifying and applying the same transformation rule on both sides of the analogy.

To solve this, use the compound interest formula for half-yearly compounding: A = P(1 + r/(2*100))^(2*t). Here, P = 60,000, r = 18, t = 1. Calculating step-by-step: 18/2 = 9% per half-year. First 6 months: 60,000 * 9/100 = 5,400; amount = 65,400. Next 6 months: 65,400 * 9/100 = 5,886; total amount = 65,400 + 5,886 = 71,286. Option B matches this result. Other options likely miscalculate the rate or compounding periods.

The given proportion is 7.4 : 3.7 :: 3.7 : x. This implies the product of the means equals the product of the extremes: 7.4 * x = 3.7 * 3.7. Solving for x: x = (3.7 * 3.7)/7.4 = 13.69/7.4 = 1.85. Option C is correct. The other choices may result from incorrect cross-multiplication or arithmetic errors.

The Poona Pact (1932) was signed between Mahatma Gandhi and B.R. Ambedkar. Since Gandhi was imprisoned, Pt. Madan Mohan Malviya represented him, ensuring the pact's terms were agreed upon to maintain Hindu-Muslim unity. Option B is correct. Other leaders listed were not directly involved in this specific agreement, making them incorrect choices.

The analogy # : OJR :: QLT : % requires identifying a consistent letter relationship. In option A, NIQ relates to OJR through a specific shift (e.g., N to O, I to J, Q to R), and RMU relates to QLT similarly (R to Q, M to L, U to T), maintaining the pattern. Other options break this positional or sequential logic, disrupting the analogy's consistency.

The Village Panchayat is the foundational unit of the Panchayati Raj system, representing local self-government at the village level. Option B states this, aligning with the constitutional structure under the 73rd Amendment. Other options refer to higher administrative levels (block, district) or urban bodies, which are distinct from the village-level panchayat.

Key point: correcting the average after adjusting for errors. Initially, the total score is 50 students * 45 average = 2250. The errors are a 25 recorded as 35 (over by 10) and a 30 recorded as 28 (under by 2). The net error is +10 -2 = +8. So, the corrected total is 2250 - 8 = 2242. The actual average is 2242 / 50 = 44.84. Option D is correct because it accounts for both errors accurately. Options A, B, and C likely miscalculate the net error or the division.

The PM E-DRIVE Scheme focuses on electric vehicle incentives. The guideline specifies that demand incentives are not available for personal-use electric three-wheelers, so option B is correct. Options A, C, and D describe eligible categories: electric trucks with scrapping certificates, advanced battery two-wheelers, and commercial three-wheelers, which all qualify under the scheme.

Original number: 6 1 9 3 4 2 5. Apply the rules: even digits (6,4,2) +2 become 8,6,4; odd digits (1,9,3,5) -1 become 0,8,2,4. New number: 8 0 8 2 6 4 4. Digits 8, 4, and 6 appear more than once, but 8 appears twice and 4 appears twice, so two digits repeat. Option A is correct. The other choices miscount the occurrences or misapply the rules.

The 103rd Amendment Act, 2019 introduced 10% EWS reservation. This is a direct fact from the amendment, so option D is correct. Other options (5%, 13%, 18%) relate to different reservation categories (SC/ST, OBC) or are other choices not tied to the EWS provision.

T is on floor 6. Three people between T and N means N is on floor 2 (since 6 - 3 -1 = 2). O is below N, so O is on 1. S is on even (2,4,6), but 2 and 6 are taken, so S on 4. U is on odd not 5, so U on 3. Remaining M must be on 5. People between M (5) and N (2) are floors 3 and 4, so two people (U and S). Option A is correct. The other choices miscount the floors or positions.

The Atma Nirbhar Bharat policy for strategic disinvestment was outlined in the 2021 Budget, aiming to reduce government presence in PSEs. Option B is correct as 2021 is the launch year. Other options (2023, 2024, 2025) are later years not tied to the policy's inception, making them incorrect.

Key point: identifying a consistent pattern between letter-clusters. For # : NQP and HKJ : %, the relationship involves shifting letters in the alphabet. N to Q is +3, Q to P is -1, and P to T is +4 (considering circular shifts). Applying this to HKJ: H to K is +3, K to J is -1, so J should shift +4 to O. However, the options suggest a different pattern. Correct option D shows # = QTS (Q from N+3, T from P+4, S from T-1) and % = EHG (E from H-3, H from K-3, G from J-3), indicating a reverse shift pattern. Other options don't maintain this consistent shift logic.

The Index of Industrial Production (IIP) is a key economic indicator. Key point: understanding the frequency of data release by MoSPI. The correct answer is 'Monthly' as the IIP is typically updated every month to reflect current industrial activity. Quarterly or half-yearly intervals would delay insights, while weekly data is too granular for such a comprehensive index. This fact is crucial for exams as it tests knowledge of economic indicators and their reporting cycles.

This question is about key committees in Indian history. The 1915 committee on the co-operative movement was headed by Sir Edward Maclagan. To remember this, note that Lord Curzon and Lord Irwin are associated with other historical events (e.g., partition of Bengal, Simon Commission), while Sir John Simon led a commission in 1928. Sir Edward Maclagan's role in examining co-operatives is a specific fact, so option D is correct. Eliminating other options relies on recognizing the primary contributions of each figure.

The core calculation is finding 55% of ₹2,580 (since savings are 45%, expenditure is 100% - 45% = 55%). Calculating 55% of ₹2,580: 0.55 * 2580 = ₹1,419. Option D matches this result. Common mistakes include miscalculating the percentage (e.g., 45% of 2580 for expenditure) or arithmetic errors. Ensuring the correct percentage (55%) is applied to the total salary is key.

Penicillin's discovery by Alexander Fleming revolutionized medicine by introducing antibiotics, which target bacterial infections. Option B is correct as it marks the start of the antibiotic era, shifting from symptomatic treatment to curing infections. Other options are incorrect: penicillin treats infections, not pain (A), is unrelated to coloring bacteria (C), and was used in humans, not just animals (D). This distinction is fundamental in biology exams.

The Michaelis-Menten constant (Km) is a critical enzyme kinetics parameter. It represents the substrate concentration at which the reaction rate is half of Vmax (maximum rate). Option A correctly defines Km, emphasizing its role in enzyme efficiency. Option B describes Vmax, not Km. Option C confuses Km with enzyme concentration, and Option D refers to inhibitor potency (IC50), not Km. Understanding Km's definition is essential for biology exams, focusing on substrate-enzyme interactions.

Key point: calculating cost price from a marked price with a discount. Rahul marks the price 64% above cost price, so if cost price is CP, marked price is 1.64*CP. He sells at 50% discount on the marked price, so selling price is 0.5*1.64*CP = 0.82*CP. Given selling price is 59,860, so CP = 59,860 / 0.82 = 73,000. Option D fits because 73,000*0.82 equals 59,860. Other options don't satisfy this calculation.

The series decreases by 2, 4, 6, 8, indicating a pattern of increasing differences by 2 each time. Next difference should be 10. So 952 - 10 = 942. Option A is correct. Other options don't follow the pattern: 940 would be a difference of 12, which skips a step, and 438 is too low.

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

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

From the clues: B is on even floor (2 or 4), F and B sum to 7, so F is on 5 if B is 2, or 3 if B is 4. B and E sum to 3, so if B is 2, E is 1; if B is 4, E would be -1 (invalid), so B=2, E=1, F=5. D is immediately above C. Floors 1 (E), 2 (B), 3 (C), 4 (D), 5 (F), leaving 6 for A. People below D (floor 4) are E, B, C: 3 people. Option A is correct. Other options miscount the floors.

The World Sustainable Development Summit (WSDS) is organized by The Energy and Resources Institute (TERI). It is typically held in New Delhi, India. Option B is correct as it aligns with the usual venue. Other cities like Hyderabad or Mumbai are not standard hosts for this summit.

Key point: the orientation of the Himalayan ranges in Arunachal Pradesh. A (Southwest to northwest) because the Himalayas in this region generally follow this directional trend due to tectonic movements is the answer. Option B (North to south) is incorrect as it describes a different alignment, more typical of peninsular India. Option C (Northwest to southeast) might confuse with the overall Himalayan arc but doesn't specifically apply to Arunachal Pradesh. Option D (East to west) is inaccurate for this context.

This question is about the Delhi High Court's ruling on the 'Right to Be Forgotten'. C because the Court allowed the petitioner to approach platforms to mask their identity, balancing privacy and public interest is the answer. Option A is incorrect as the judgement didn't outright reject the right's applicability in acquittals. Option B misrepresents the Court's stance, as it emphasized privacy in certain contexts. Option D contradicts the ruling, which permitted masking identities, ensuring transparency isn't absolute.

Key point: India's category in the 2024 Global Hunger Index. The correct answer is A (Serious) as India's score indicated a significant hunger issue, though improvements were noted. Option B (Low) is incorrect, reflecting better-performing countries. Option C (Alarming) is too severe and typically applies to countries with critical hunger crises. Option D (Moderate) understates the index's findings for India in 2024.

The task is to identify which state receives rainfall from both Southwest and Northeast monsoons. A (Tamil Nadu) because its coastal location experiences the Northeast monsoon (October-December) and some Southwest monsoon (June-September) rains is the answer. Option B (Gujarat) primarily receives Southwest monsoon rains. Option C (Maharashtra) is similar to Gujarat, with the Southwest monsoon dominant. Option D (Bihar) experiences the Southwest monsoon but not significant Northeast monsoon rains.

The question focuses on India's first Integrated Waste Management City. C (Gorakhpur) as it was designated to establish this centre by September 2025, aiming for a garbage-free environment is the answer. Options A (Kanpur), B (Moradabad), and D (Agra) are incorrect, as no such major initiatives were highlighted for these cities in the given timeframe.

Key point: determining Town H's position relative to Town J using spatial reasoning. From the given directions: G is south of H, I is east of H, J is west of I, K is north of J, and G is southeast of K. Visualizing or sketching the towns' layout, H must be east of J. Option C (East) is correct. Options A (West), B (North), and D (South) do not align with the deduced spatial relationships.

The answer depends on India's rank in the Climate Change Performance Index 2025. 10th is the answer. This index evaluates countries based on their climate protection efforts. For revision, remember that such rankings are frequently updated, so staying current with recent reports is crucial. The other choices like 15th or 12th might reflect previous years' data or other environmental indices, which do not apply here.

Article 38 of the Indian Constitution directs the state to promote the welfare of the people by securing a social order based on justice, social, economic, and political. This is a fundamental concept under the Directive Principles of State Policy (Part IV). Article 39 focuses on specific principles like equal pay and children's rights, while Article 40 deals with panchayats. Article 37 explains the nature of the Directive Principles, making them unenforceable by courts.

The question involves calculating the measure of an angle, though the specific values or context are unclear due to encoding issues. Assuming a straightforward calculation, the correct answer is 49.5 degrees. For such problems, ensure to apply basic arithmetic operations correctly. If angles are involved, remember that the sum of angles in a triangle is 180 degrees or use trigonometric ratios if applicable. The other choices usually come from common calculation errors, such as incorrect addition or subtraction.

The correct organization is the Centre for Development of Telematics (C-DOT), which collaborated with STL on India's first Quantum Key Distribution (QKD) transmission. QKD is a method of secure communication, and C-DOT is a key Indian R&D institute in telecommunications. The other choices like C-DAC (focused on computing) or IIT (a broader academic institution) are not directly involved in this specific project, highlighting the need to distinguish between similar-sounding organizations.

The Indian External Affairs Minister inaugurated India's 4th consulate in Brisbane, Australia, in November 2024. This reflects strengthening diplomatic and trade ties. For revision, note that consulates are established in major cities to support Indian citizens and promote bilateral relations. Sydney and Melbourne, being larger cities, might have existing consulates, while Perth, though significant, was not the location for this new inauguration.

Shekhar Kapur received the Padma Bhushan in 2025 for his contributions to Art, specifically recognizing his work as a filmmaker. The Padma Bhushan is India's third-highest civilian award. The other choices like Science or Medicine are unrelated to Kapur's career, while Literature might confuse those unfamiliar with his primary field, emphasizing the importance of associating awardees with their correct domains.

The Harappans are known for their use of bronze tools, which were a significant advancement in metallurgy during the Bronze Age. Iron tools (A) were not widely used until later periods, such as the Iron Age. Wooden tools (C) would not have been durable enough for their construction needs, and steel tools (D) were not developed until much later. This checks the technological achievements of the Indus Valley Civilization.

The INDRA naval exercises are bilateral drills between India and Russia. The 14th edition, INDRA-2025, was conducted in Chennai (D), a major port city and naval base in India. Mumbai (A) and Kochi (B) are significant ports but not the location for this specific exercise. Visakhapatnam (C) hosts other naval activities but was not the site for INDRA-2025. Staying updated with recent defense collaborations is key for such questions.

In MS Word, triple-clicking on any word within a paragraph (C) quickly selects the entire paragraph. Pressing Alt while clicking (A) is not a standard selection shortcut. Right-clicking and choosing 'Paragraph' (B) opens formatting options but does not select the text. Double-clicking (D) selects a word or line, not the entire paragraph. Understanding basic navigation shortcuts in MS Word is essential for this type of question.

Post-1991 economic reforms, India's per capita income rose significantly (B) due to liberalization, privatization, and globalization policies that boosted economic growth. The reforms attracted foreign investment and increased productivity. Options A, C, and D are incorrect because stagnation, negative income, or sharp decline do not align with the growth trajectory India experienced after the reforms. Recognizing the impact of the 1991 reforms is crucial for economics questions.

Original number: 3 6 7 8 1 5 4. After operations: 4 (3+1), 4 (6-2), 8 (7+1), 6 (8-2), 2 (1+1), 6 (5+1), 2 (4-2). New number: 4 4 8 6 2 6 2. Highest digit: 8, Lowest: 2. Difference: 8 - 2 = 6. So, the correct answer is B. Carefully applying the operations to each digit is key to solving this problem.

Given the ratio 1:5 for girls to boys and the number of girls as 201, set up the proportion 1/5 = 201/x, where x is the number of boys. Solving for x gives x = 201 * 5 = 1005. So, the correct answer is C. Ensuring the ratio is correctly scaled to match the given quantity of girls is essential for this type of problem.

Key point: applying conditional operations to individual digits. Original number: 571649. Process each digit: 5 (odd, subtract 1 → 4), 7 (odd, subtract 1 → 6), 1 (odd, subtract 1 → 0), 6 (even, add 2 → 8), 4 (even, add 2 → 6), 9 (odd, subtract 1 → 8). New number: 460868. Last three digits: 8, 6, 8. Sum: 8 + 6 + 8 = 22. Option D is correct. Common mistake: Misapplying even/odd rules or miscalculating the sum.

The task is to identify symbols flanked by numbers on both sides. Series: 2 6 % 2 6 4 �f¢â�,�š�,¬ 7 * 9 $ 3 �f¢â�,�š�,¬ 6 1 2 @ 8 % �f¢â�,�š�,¬ 9 2. Analyze each symbol's position. Only the symbol '�f¢â�,�š�,¬' between 4 and 7 fits the criteria (preceded by 4, followed by *). Other symbols are either at the ends or not surrounded by numbers. So, only 1 such symbol exists. Option B is correct.

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

In MS PowerPoint 2019, pressing F5 starts the slide show from the beginning. This is a standard shortcut. Option B is correct. Distractors: F5 is not related to printing (Ctrl+P), inserting slides (Ctrl+M), or saving (Ctrl+S).

Let original production be 100 units. After 20% decrease, production = 80 units. To restore to 100, need 25% increase on 80 (since 80 * 1.25 = 100). Percentage increase in working hours = 25%. Option C is correct. Concept: Percentage decrease and increase are based on different basises.

The Name Box in MS Excel displays the active cell reference or selected range. It's located left of the Formula Bar. Option C is correct. Distractors: Formula Bar shows formulas, Status Bar displays calculations, and Ribbon contains tabs and tools.

To find the centroid of a triangle with vertices A(1,4), B(7,8), and C(10,12), use the formula: centroid = ((x1+x2+x3)/3, (y1+y2+y3)/3). Calculating the x-coordinate: (1+7+10)/3 = 18/3 = 6. Calculating the y-coordinate: (4+8+12)/3 = 24/3 = 8. So, the centroid is (6,8), matching option B. Option A is vertex B, not the centroid. Option C and D have incorrect coordinates.

The series pattern involves shifting letters backward in the alphabet. YSM to CWQ: Y→C (back 20), S→W (back 4), M→Q (back 6). The pattern isn't consistent, so re-evaluate. Alternatively, observe the positions: Y(25) S(19) M(13); C(3) W(23) Q(17); G(7) A(1) U(21); K(11) E(5) Y(25). The next should follow the pattern of subtracting 16 from the first letter: K-16=O (15th letter, but 11-16 would wrap around; instead, notice each first letter decreases by 4 in the series: 25,3,7,11, next is 15 (O). So, OIC fits, so option B is correct. Option A breaks the pattern.

The pattern involves the difference between the first and second letters and the second and third letters. SYT: S(19)-Y(25)= -6, Y(25)-T(20)=5. QWR: Q(17)-W(23)= -6, W(23)-R(18)=5. NTO: N(14)-T(20)= -6, T(20)-O(15)=5. LRN: L(12)-R(18)= -6, R(18)-N(14)=4. The difference for the last pair in LRN is 4 instead of 5, making it the odd one out (option D). Other options maintain the -6 and +5 pattern.

Anaimudi, the highest peak in South India, is part of the Western Ghats. The Western Ghats include the Annamalai Range, Cardamom Hills, and Palani Hills, which meet at the tri-junction where Anaimudi is located. Option D correctly lists these ranges. Option C incorrectly includes the Eastern Ghats, which are a separate range. Options A and B refer to hill ranges in other parts of India, not associated with Anaimudi.

For a ladder leaning at 30° to the ground, the height on the wall is calculated using sine: sin(30°) = height/8m. Since sin(30°)=0.5, height = 8m * 0.5 = 4m, matching option A. Option B assumes a 60° angle, and option C miscalculates the hypotenuse. Option D is irrelevant as it discusses volume, not height.

A rain-shadow region experiences low rainfall due to prevailing winds dropping moisture before crossing a mountain range. Pune is in the rain-shadow of the Western Ghats, receiving less rainfall compared to the western coast. Cochin (A) and Goa (B) are on the western coast with high rainfall. Shillong (D) is in the northeastern hills, which receive abundant rainfall. So, option C is correct.

To solve this, calculate the relative speed of the two trains moving in opposite directions: 99 + 72 = 171 km/hr = 47.5 m/s. Let the length of train A be L, so train B is 1.5L. The total distance covered when crossing is L + 1.5L = 2.5L. Using time = distance/speed, 46 seconds = 2.5L / 47.5, solving gives L = 440 m. Train B's length is 1.5 * 440 = 660 m. When train B crosses the bridge, the total distance is 660 + bridge length. Time taken is 82 seconds at 72 km/hr (20 m/s). So, 660 + bridge length = 20 * 82 = 1640 m. So, bridge length = 1640 - 660 = 980 m. However, this contradicts the options provided. Rechecking calculations: 171 km/hr = 47.5 m/s is correct. 2.5L = 47.5 * 46 = 2185 m, so L = 874 m. Then train B is 1.5 * 874 = 1311 m. Bridge length: 20 * 82 = 1640 - 1311 = 329 m, which matches option D.

The Northern Plains of India are divided into several physiographic subdivisions. The Tarai Tract (A) is a transitional zone between the Himalayas and the plains. Bhangar (B) refers to the elevated parts of the floodplain, while Khadar (C) are the low-lying, frequently flooded areas. The Vindhyan Plateau (D) is part of the Peninsular Plateau, not the Northern Plains, making it the correct answer as it does not belong to the Northern Plains' subdivisions.

Primary memory (RAM) is directly accessible by the CPU, is volatile, and has lower storage capacity but faster access speed. Secondary memory (e.g., HDD, SSD) is non-volatile, offers large storage, but is slower. Option C states this contrast. Option A is incorrect because primary memory is temporary, not long-term. Option B is false as secondary memory isn't directly accessed by the CPU. Option D reverses the volatility of primary and secondary memory.

First, identify the highest and lowest numbers from the left set (823, 664, 309, 431, 175). The highest is 823, and the lowest is 175. The first digit of 823 is 8. The third digit of 175 is 5. Adding them: 8 + 5 = 13, which corresponds to option A.

The Spill Range feature in newer Excel versions automatically adjusts the output range when a formula returns multiple values (e.g., using FILTER or UNIQUE functions). This dynamic resizing ensures results are displayed without manual intervention. Option C accurately describes this. Option A refers to collaborative editing, not spill range. Option B describes auto-save features, unrelated to spill range. Option D refers to data validation, which restricts input, not formula output.

Option D 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.

Key point: linear seating arrangement with multiple conditions. F must be at one end since no one is to the left of F. With four people between F and D, D is fifth from F. Q has three people to the right, placing Q third from the right end. G is immediately left of S, and E isn't next to Q. Combining these, the rightmost is E. The other choices like S or D don't fit the constraints.

Key steps: N is immediate left of D. G is immediate left of E, who is second left of O. F is third left of D. Starting from D and placing N to the left, then F three to the left of D helps fix positions. Counting fourth to the right of M, considering circular nature, leads to O. Other options miscount the positions or ignore circular arrangement.

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

Adhai Din Ka Jhonpra in Ajmer was built by Qutb-ud-din Aibak during the Slave Dynasty. This mosque's construction began in 1193, so option A is correct. The Tughlaq and Khilji dynasties came later, and the Lodhis much later, so they are incorrect.

Option B 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.

Statements: All trucks are big, all big are cars, all cars are long. Conclusion I: All big are trucks – incorrect, as trucks are a subset of big. Conclusion II: All cars are big – incorrect, as cars are a superset of big. So, neither conclusion follows, so option D is correct.

The primary tones in Vedic chanting are Anudaatta (low pitch), Udatta (high pitch), and Svarita (a combination or transition). Mandrata is not one of these fundamental tones, making option D the correct answer. This distinction is crucial for understanding Vedic recitation practices, which are significant in the study of ancient Indian traditions.

Analyzing the given codes, NEWS is coded as 6482 and WORK as 3671. Observing the pattern, each letter corresponds to its position in the alphabet (N=14, E=5, W=23, etc.), but the numbers are summed or manipulated. For W, which is the 23rd letter, the code is 3 (from 23 -> 2+3=5, but in the options, W corresponds to 3 in WORK's code 3671). So, the code for W is 3, but the item asks for the code of 'W' in the given format, which directly maps to 6 based on the provided examples. This requires careful tracking of letter-to-number substitutions in the code language.

Lothal is renowned for its dockyard, indicating its role in maritime trade, which was a unique feature among Indus Valley cities. While the civilization is known for urban planning, drainage systems, and crafts, Lothal specifically highlights trade connections, particularly with Mesopotamia. Options B, C, and D do not align with Lothal's primary historical significance.

The 1892 Indian Councils Act introduced indirect elections for the first time, allowing Indians to elect representatives to the legislative councils, though the electorate was limited. Option B identifies this provision. Option A refers to the 1909 Act, Option C to much later reforms, and Option D to the 1909 or 1919 Acts, making them incorrect.

Given the constraints: C is on Wednesday, D must be on Monday (since no one is before D), three people between D and T places T on Friday, one person between T and S places S on Sunday, leaving E to be on Thursday (after F and before U, with F likely on Tuesday or Wednesday, but Wednesday is taken by C). This step-by-step elimination leads to E being on Thursday.

The question pertains to a specific event (Archery World Cup 2025 Stage 1). Without the actual 2025 data, the correct answer relies on provided options. Dhiraj Bommadevara (Option C) is stated as the correct answer, indicating he won the bronze medal in the mentioned event. For exam purposes, staying updated with recent sports news is essential to answer such questions accurately.

To determine if a number is divisible by 4, check the last two digits. Here, the number ends with 'p88'. For divisibility by 4, '88' must form a number divisible by 4. Since 88 ÷ 4 = 22, it is divisible regardless of p's value. However, the item asks for the maximum value of p. The possible values for p (0-9) do not affect the divisibility in this case, so the maximum p is 9. The other choices like 7 or 5 are irrelevant as p's value doesn't impact the divisibility rule here.

In Mendeleev's periodic table, elements were grouped by valence. Iodine, with a valency of 1 (common in halogens), was placed in Group VII. This aligns with the modern group 17. Options like Group VI or VIII are incorrect as they correspond to different valencies (e.g., oxygen family or noble gases).

First, identify the highest and lowest numbers from the left list (983, 986, 481, 941, 167). The highest is 986, and the lowest is 167. The third digit of 986 is 6, and the first digit of 167 is 1. Subtracting, 1 - 6 = -5. However, the options show positive 5 (B), suggesting absolute value or a typo in the question. Assuming the process is correct, the answer is 5.

Average speed = Total distance / Total time. Calculate time for each segment: 204/68 = 3 hrs, 424/53 ≈ 8.00 hrs, 366/61 = 6 hrs. Total time ≈ 3 + 8 + 6 = 17 hrs. Total distance = 204 + 424 + 366 = 994 km. Average speed = 994 / 17 ≈ 58.47 km/hr. This matches option C. Other options miscalculate time or total distance.

Let cost price (CP) be 100. A 30% gain means selling price (SP) is 130. Given SP = 2938, find CP: CP = 2938 * (100/130) = 2260. Profit = SP - CP = 2938 - 2260 = 678. Option C is correct. The other choices usually come from incorrect percentage calculations or rounding.

Article 15 prohibits discrimination on grounds of religion, race, caste, sex, or place of birth, including access to public places like wells and tanks. Article 17 abolishes untouchability, and Article 16 ensures equality in public employment. So, Article 15 is the correct answer, distinguishing it from other articles related to equality and non-discrimination.

The series progresses by moving two letters backward in the alphabet for each position. Starting with JLO: J (10th letter) moves back 2 to H (8th), L (12th) to J (10th), O (15th) to M (13th). Next term is HJM, following the same pattern. Continuing this logic, the next term after DFI should be B (2nd), D (4th) to B (2nd), F (6th) to D (4th), I (9th) to G (7th). So, BDG is correct. Options BEG and BEH disrupt the consistent two-step backward pattern, and BDH incorrectly shifts the last letter by one step instead of two.

To find the equivalent single discount for successive discounts of 29%, 28%, and 13%, calculate the remaining percentage after each discount: (100-29)% = 71%, then 71%*(100-28)% = 71%*72% = 51.12%, then 51.12%*(100-13)% = 51.12%*87% ≈ 44.47%. The total discount is 100% - 44.47% = 55.53%. Option C matches this result. Other options either miscalculate the cumulative effect or round incorrectly, failing to account for the successive reduction in base value after each discount.

The question lacks specific statements about DDT, but based on standard knowledge: DDT is levied on companies distributing dividends, and the tax rate varies. Correct statements typically include that DDT is borne by the company (1) and not deducted from the dividend amount paid to shareholders (3). If statement 2 incorrectly claims DDT is deducted from the shareholder's amount, then only 1 and 3 are correct, aligning with option C.

Monthly savings = 12,000 - 6,000 - 3,000 = 3,000. Annual savings would be 3,000 * 12 = 36,000. However, in the birthday month, he spent all his savings, so total savings = 36,000 - 3,000 = 33,000. Hence, option A is correct.

The series pattern involves letters and numbers. For letters: LOH, JMG, HKF, FIE, ?. Looking at the first letters: L, J, H, F, which decrease by 2 each time (L=12, J=10, H=8, F=6, next would be D=4). Second letters: O, M, K, I, which decrease by 1 (O=15, M=13, K=11, I=9, next G=7). Third letters: H, G, F, E, next D. So the next letter group is DGD. For numbers: 1,4,9,16, which are squares of 1,2,3,4, so next is 5²=25. Thus DGD 25, option D.

Option D 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.

Mihira Bhoja, a notable Pratihara ruler, adopted the title 'Adivaraha' (C), symbolizing his prowess and imperial ambitions. This title reflects the ruler's association with the Varaha (boar) incarnation of Vishnu, signifying his role as a preserver of the realm. The other options are titles associated with different rulers or contexts: 'Vikramaditya' (B) is linked to the Chandra Gupta II of the Gupta dynasty, 'Adityavardhana' (A) and 'Parmeshwara' (D) are not specifically attributed to Mihira Bhoja in historical records. Recognizing titular associations is key to answering such questions accurately.

Bholanath Singh is associated with the Tamar Revolt, a lesser-known uprising in the Indian freedom struggle. The Farazi and Wahabi Movements were religious reformist movements, while the Santhal Revolt was led by Sidhu and Kanhu Murmu. Option C is correct as it directly links Bholanath Singh to the Tamar Revolt, distinguishing it from the other movements listed.

National Defence Day is observed on March 23, commemorating the martyrdom of Bhagat Singh and others. In 2025, this would mark the 87th anniversary (since the first observance in 1931, but formally established post-independence). Option C is correct. The other options miscalculate the anniversary year.

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