RRB Group D Previous Year Paper 01 Dec 2025 - 12:45 PM - 2:15 PM

Nucleons are the subatomic particles in the nucleus. Key point: the composition of the atomic nucleus. Option C is correct because nucleons include both protons (positively charged) and neutrons (neutral). Option A is incorrect as it excludes protons, and Option D is incorrect as it excludes neutrons. Option B is incorrect because electrons are not part of the nucleus; they orbit around it.

The rough appearance of the RER is due to attached ribosomes. Ribosomes are responsible for protein synthesis, and their presence on the RER's surface gives it a rough texture under a microscope. Option C is correct. Options A, B, and D refer to other organelles: peroxisomes (detoxification), lysosomes (digestion), and centrosomes (cell division), none of which affect the RER's texture.

The prostate gland is part of the male reproductive system, contributing fluids to semen. Option B is correct. Options A, C, and D (uterus, vagina, fallopian tubes) are female reproductive organs, making them incorrect choices.

The heart is an organ, not a cellular structure. This checks cellular components. Option B is correct as the heart is not a part of a cell. Options A, C, and D (cell wall, mitochondria, cytoplasm) are all recognized parts of a cell, though the cell wall is specific to plant cells.

Option C is marked correct. For this Physics question on Electric Power and Heat, revise the basic principle and check which option matches the definition, process, or example asked in the question.

A stable solution has uniformly distributed solute particles. Option D is correct because stability means particles do not settle over time. Options A and C describe unstable mixtures (e.g., suspensions), where particles eventually settle or separate. Option B refers to immiscible liquids forming layers, not a solution.

Key point: electrolytic refining, where the anode is the source of metal ions. D because the impure metal strip serves as the anode, dissolving into the solution is the answer. Option A describes the cathode, which is where pure metal deposits. Options B and C refer to inert electrodes used in other electrolytic processes, not specifically in refining where the metal itself acts as the anode.

Kinetic energy (KE) is calculated as ½mv². If velocity (v) doubles, the KE becomes ½m(2v)² = 4*(½mv²), which is four times the original. This eliminates options A, C, and D, which incorrectly apply the velocity factor. The calculation clearly shows the squared relationship between velocity and KE.

Newton's First Law states that an object in motion stays in motion unless acted upon by an external force. When the bus stops, the person's inertia keeps them moving forward relative to the bus, causing them to fall. Options A and D involve action-reaction pairs and momentum conservation, which are not directly related to the tendency to maintain motion. Option B relates to force and acceleration, which is not the primary factor here.

A formula unit represents the simplest ratio of ions in an ionic compound. The correct definition (C) emphasizes the sum of atomic masses in this unit, which is distinct from molecular mass (D) or molar mass (B). Option A refers to atomic mass, not the compound's formula unit. This distinction is crucial for calculating amounts in chemical reactions.

Fleming's Left-Hand Rule correlates the direction of magnetic field (index finger), current (middle finger), and motion (thumb). The thumb specifically points in the direction of the force or motion, so option C is correct. Other options misassign the fingers, which could lead to incorrect application of the rule in motor operation problems.

The Law of Constant Proportions states that elements combine in fixed ratios by mass. The correct answer (D) indicates that statements a and b align with this law, assuming they describe consistent composition across samples. Options involving statement c might refer to variable proportions in compounds, which would not fit the law. Understanding this law is key to grasping stoichiometry and chemical formulas.

Key point: the role of genetic variation in natural selection. Option C is correct because variation allows some individuals to survive environmental changes, ensuring the population's survival. Option A is incorrect as reproduction speed isn't directly tied to variation. Option B contradicts the premise, as variation ensures differences, not uniformity. Option D is wrong because evolutionary benefits often manifest over generations, not instantly.

This checks human anatomy. The kidneys are located in the abdomen, not the chest, eliminating options A and B. Between C and D, the precise location is on either side of the backbone (vertebral column), making D correct. The intestine's position is more central, so C is inaccurate. This distinction is crucial for understanding the urinary system's structure.

Parthenium is an invasive weed that harms crops and livestock, making its removal beneficial. Options B, C, and D are all crops (soybean, wheat, sunflower), not weeds, so removing them would be detrimental to farmers. This question assesses the ability to identify harmful species in an agricultural context, emphasizing the impact of invasive plants on crop productivity.

This question focuses on vegetative propagation. Sweet potatoes can regenerate plants from their roots, a common method of asexual reproduction. Potato plants typically arise from tubers (modified stems), not roots, eliminating A. Maize and gram do not propagate from roots, making B and C incorrect. Understanding plant parts and their reproductive roles is key here.

To balance the combustion reaction of C2H6: 2C2H6 + 7O2 � 4CO2 + 6H2O. Start with C: 2*2 = 4 CO2. Hydrogen: 2*6 = 12, so 6 H2O (12 H). Oxygen: 4*2 + 6 = 16, requiring 7 O2 (14 O to balance 16 from products, considering 2 from 7 O2). Option D matches this stoichiometry. Other options fail to balance elements correctly, demonstrating the step-by-step balancing method.

Dispersion occurs because different wavelengths (colours) of light travel at different speeds in glass, causing them to bend by varying amounts. Option C states this principle. Option A is false, as differing speeds are the cause. Option B is irrelevant, as absorption isn't the mechanism. Option D is incorrect because white light comprises multiple colours, not just one. This explains the rainbow effect seen with prisms.

Key point: the distinction between mass and weight. Mass is a measure of the amount of matter in an object and remains constant regardless of location. Weight, however, is the force exerted on that mass due to gravity, which varies with changes in gravitational acceleration (e.g., on different planets). Option B states that mass is constant and weight is variable. Options A and D incorrectly suggest mass varies or both are constant, ignoring the dependency of weight on gravity. Option C is incorrect because weight is not always constant.

When hydrocarbons undergo complete combustion in excess air, they react with sufficient oxygen to produce carbon dioxide and water as the only products. Option D is correct because it accurately reflects this complete combustion process. Options A and B are incorrect as they mention carbon monoxide, which is a product of incomplete combustion. Option C is incorrect because hydrogen is not a typical product of hydrocarbon combustion in excess oxygen; water is formed instead.

The phenomenon described is dispersion, where white light splits into its constituent colors due to differing wavelengths. The resulting band of colors is called a spectrum. Option D is correct as 'spectrum' directly refers to this colorful display. Options A, B, and C are incorrect: an image is a representation of an object, a shadow is an area without light, and a reflection pattern refers to how light bounces off surfaces, none of which specifically describe the colored band from dispersion.

The loudness of a sound wave is determined by its amplitude, with larger amplitudes producing louder sounds. Since the question specifies the same frequency, speed and wavelength (which are related to frequency) remain unchanged. Option C identifies larger amplitude as the characteristic of a louder sound. Options A and B are incorrect because speed and wavelength are not directly related to loudness in this context. Option D is incorrect because pitch is determined by frequency, not amplitude.

A neutralization reaction involves an acid and a base reacting to form salt and water. This is a fundamental concept in acid-base chemistry. Option A describes this reaction. Options B, C, and D are incorrect: B refers to a reaction involving an oxide (not a typical neutralization), C describes a reaction between an acid and a salt (which does not produce water as the primary product), and D describes a metal-acid reaction (which produces hydrogen gas, not water as the sole product).

Inter-cropping is the practice of growing two or more crops simultaneously on the same land in a specific pattern to promote ecological interactions and synergies. Option B is correct as it directly defines inter-cropping. Option A refers to monocropping, which involves growing a single crop. Options C and D describe soilless cultivation methods (aeroponics and hydroponics), which are unrelated to the simultaneous cultivation of multiple crops on the same field.

Key point: Newton's third law of motion, which states that every action has an equal and opposite reaction. When the swimmer pushes water backwards, the water exerts a reaction force in the forward direction. Option B identifies this reaction force as the water pushing the swimmer forward. Option A is incorrect because gravity acts downward, not forward. Option C misstates the direction of the force exerted by the water. Option D is irrelevant since air resistance is negligible compared to the force from water in this scenario.

The question appears to be incomplete or contains corrupted text, making it unanswerable as provided. However, based on the options given (all in centimeters), it seems to relate to calculating a length or distance in a geometric figure. Without the full question, the correct answer (B: 56 cm) cannot be verified. Typically, such problems involve applying formulas for perimeter, area, or volume of shapes like triangles, rectangles, or circles. Ensure all given information is used to derive the solution.

The question is incomplete or corrupted, but the options suggest a pattern recognition or arithmetic operation problem. D: 330 is the answer. A common approach involves identifying sequences (e.g., multiples of a number) or applying basic arithmetic operations. For example, if the pattern involves adding or multiplying numbers in a series, the next term would follow logically. Without the full question, the reasoning for selecting 330 cannot be fully articulated, but it typically involves recognizing a consistent mathematical relationship between the numbers provided.

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

The cost price (CP) is �10,720, and the selling price (SP) is �9,862.40. Since SP < CP, there's a loss. Loss = CP - SP = 10,720 - 9,862.40 = �857.60. Loss percentage = (Loss/CP) * 100 = (857.60/10,720) * 100 � 8%. Option A is correct. To verify: 10% of 10,720 is 1,072, which is more than the actual loss, so the percentage must be less than 10%, confirming 8% as the accurate choice.

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

The ratio of red to green tokens is 14:8, which simplifies to 7:4. The ratio of pink to red tokens is 2:6, simplifying to 1:3. To find the ratio of green to pink, express all in terms of red. If red = 7*3 = 21, green = 4*3 = 12, and pink = 7*1 = 7. So, green:pink = 12:7. Option D is correct because it directly matches this ratio, while others do not align with the proportional relationships established.

First, calculate individual work rates. A's rate = 1/3, B's rate = 1/2, C's rate = 1/6. Combined rate = 1/3 + 1/2 + 1/6 = (2 + 3 + 1)/6 = 6/6 = 1 work per day. Thrice the work would take 3 days for the combined rate of 1 work/day. Option A is correct as the calculation clearly shows the combined efficiency leads to completing thrice the work in 3 days.

Option D 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.

Volume of the original sphere = (4/3)�(10.5)^3. Volume of each smaller sphere = (4/3)�(3.5)^3. Number of smaller spheres = (10.5/3.5)^3 = 3^3 = 27. Total surface area of smaller spheres = 27 * 4�(3.5)^2. Surface area ratio = [27 * 4�(3.5)^2] / [4�(10.5)^2] = 27 * (3.5/10.5)^2 = 27 * (1/3)^2 = 27/9 = 3:1. Option D is correct as the ratio of surface areas directly results from the cube of the radius ratio.

Option B 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.

Total distance = (20 * 80) + (55 * 60) = 1600 + 3300 = 4900 m. Total time = 80 + 60 = 140 min. Average speed = 4900 / 140 = 35 m/min. Option B is correct as it directly results from dividing total distance by total time, a standard formula for average speed.

The question involves calculating the length of a path or distance, likely related to a geometric figure. The correct answer, 57 m, suggests a perimeter or distance formula application. Common mistakes might involve incorrect formula usage or arithmetic errors. For instance, if the figure is a rectangle with given dimensions, perimeter = 2*(length + width). If length and width were 20m and 8.5m, perimeter would be 2*(20+8.5)=57m. The other choices (56, 58, 59) might result from miscalculations like adding instead of doubling the sum.

The mode is the most frequent value. Given data: 8,7,8,7,9,10,2,8,9,7,5,10,x. Existing frequencies: 8 appears 3 times, 7 appears 3 times. For mode to be 7, x must be 7 to increase its frequency to 4, making it the sole mode. If x were 8, both 7 and 8 would be modes (bimodal), which contradicts the question. So, x=7 (B) is correct. The other choices assume x alters the mode differently, but only 7 ensures it's the unique mode.

Let Pushpraj's investment be P and Himani's be 17800-P. Profit sharing ratio is P:(17800-P). Pushpraj's share is 2100, so ratio is 2100:(5600-2100)=2100:3500=3:5. So, P/(17800-P)=3/5 � 5P=3*(17800-P) � 5P=53400-3P � 8P=53400 � P=6675. So, Pushpraj's investment is 6675 (B). The other choices may result from incorrect ratio setup or algebraic mistakes.

Prime numbers between 146 and 196 are: 149,151,157,163,167,173,179,181,191,193. Total 10 primes. To count, check divisibility for each number in the range. The other choices (11,12,13) might include non-primes or miscount. For example, 187 (11*17) is not prime. Careful checking confirms 10 primes, making D correct.

Let son's age = S, daughter = S+3, mother = 2S, father = 2S+3 (since father-mother difference is 3). Total age: S + (S+3) + 2S + (2S+3) = 6S +6 =144 � 6S=138 � S=23. Daughter's age =23+3=26 (D). The other choices may arise from incorrect variable setup. For instance, if son's age were not half the mother's, equations would mismatch. Correct setup leads to daughter being 26.

The question likely involves area or volume calculation, possibly of a composite figure. Correct answer 49.2 suggests a decimal result, common in area problems (e.g., triangle area = 1/2 * base * height). If the figure were a trapezoid with bases 10 and 20, height 4.8, area = (10+20)/2 *4.8=49.2. The other choices (46.3,54.5,51.6) might result from incorrect formula application or measurement mix-up (e.g., using radius instead of diameter).

First, calculate the total cost before discounts: 250 mixers * �1,014 = �253,500. Apply successive discounts: 30% off (�253,500 * 0.7 = �177,450), then 15% off (�177,450 * 0.85 = �150,832.5). Finally, apply the 20% card discount: �150,832.5 * 0.8 = �120,666. Option A is correct as it matches the final amount. Other options likely miscalculate discount sequences or percentages.

Use the compound interest formula A = P(1 + r/100)^n. Here, P = �7,700, r = 10, n = 2. Calculate for 1st year: �7,700 * 1.1 = �8,470. For the 2nd year: �8,470 * 1.1 = �9,317. Option D is correct. Other options may apply simple interest or miscalculate the compounding.

First, find the train's speed: 1533 m / 73 s � 21 m/s. To cross a 420 m platform, the total distance covered is 1533 + 420 = 1953 m. Time taken = 1953 / 21 � 93 seconds. Option B is correct. Other options may incorrectly calculate speed or total distance.

Original savings: 27% of �12,000 = �3,240. New income: �12,000 * 1.2 = �14,400. New expenditure: (100 - 27)% of �12,000 * 1.15 = �8,760 * 1.15 = �10,074. New savings: �14,400 - �10,074 = �4,326. Increase in savings: �4,326 - �3,240 = �1,086. Option B is correct. Other options may miscalculate percentage changes or savings difference.

Let the smallest piece be x. Largest is 3x. Middle piece is y. Given: x + y + 3x = 24 and y - 3x = x - y. Solving these, we get x = 4, y = 8, largest = 12. Option B is correct. Other options may misassign variables or incorrectly solve equations.

Discount = �4,000 - �280 = �3,720. Discount percentage = (�3,720 / �4,000) * 100 = 93%. Option D is correct. Other options may incorrectly calculate the discount amount or percentage.

Key point: identifying the pattern in the letter triads. Each group of letters is rearranged by moving the first letter to the end. For JOBS to JSBO, J moves to the end. Applying this logic, OILY becomes OYLI, and the next should follow the same rotation. Option C (EARN - ENRA - NRAE) correctly applies this rotation, whereas other options disrupt the sequence. For example, A's KIDS to KDIS skips a step, and B's GAVE to AGVE changes multiple letters' positions, which doesn't fit the established pattern.

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

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

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

The series is 2 8 1 7 3 6 6 6 1 5 5 3 4 1 5 5 3 9 7 7 7. We need to find even digits that are both preceded by an even digit and followed by an odd digit. Checking each even digit: 8 (preceded by 2-even, followed by 1-odd) - valid. 6 (preceded by 3-odd, followed by 6-even) - invalid. Next 6 (preceded by 6-even, followed by 6-even) - invalid. Next 6 (preceded by 6-even, followed by 1-odd) - valid. Then 4 (preceded by 3-odd, followed by 1-odd) - invalid. The valid ones are 8 and the third 6, totaling 2. So, the answer is B.

Rashmi starts at A, goes 5 km west, then right (north) 4 km, right (east) 3 km, left (north) 4 km, right (east) 2 km. Tracking movements: West 5, North 4, East 3 (net West 2), North 4, East 2. Final position: 2 km West and (4+4)=8 km North from A. To return, she needs to go 2 km East and 8 km South. The shortest distance is the hypotenuse of 2 and 8: sqrt(2²+8²)=sqrt(68)�8.25 km, but the options suggest cardinal directions. Since she is 8 km North and 2 km West of A, the shortest path is 8 km South and 2 km East, but the options combine distance and direction. The answer is 8 km towards south, as the primary displacement is North, requiring Southward movement to return, with Eastward movement being minor and possibly incorporated into the 'shortest distance' as a direct path, but the options don't account for diagonal movement, so the closest is B.

Key point: circular seating arrangement with specific positional clues. Starting with X, two people between X and W means W is three seats to the right of X. Then, two people between W and M places M three seats to the right of W. Three people between X and N positions N four seats to the right of X. P is immediately left of Y. By plotting these positions clockwise: X, _, _, W, _, _, M, and N four seats from X, the arrangement can be deduced. The only position left for O must be such that Y is third to the left of O, making D (Y) the correct answer. Other options don't fit the deduced arrangement.

Key point: calculating total students from rank positions. Tanay's rank from the top is 24th, and from the bottom is 56th. To find total students, add the rank from top and bottom and subtract 1 (since Tanay is counted twice). So, 24 + 56 - 1 = 79. Option D is correct. Other options result from incorrect addition or subtraction.

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

Key point: identifying the odd one out based on alphabetical patterns. EFH, MNP, and XYA follow a pattern of consecutive letters with one letter skipped (e.g., E-F-H skips G). However, FHI skips G but also breaks the consecutive sequence after H, which isn't the case here. Actually, FHI is consecutive without skipping, unlike the others that skip one letter. So, B (FHI) is the odd one out. The explanation in the question's note clarifies it's not about consonants/vowels, focusing on sequence instead.

Key point: tracking movement on a grid. Starting at A, Shubham moves West 10 km, then right (North) 8 km, right (East) 14 km, right (South) 12 km, and finally right (West) 4 km. Net movement: West 10 - East 14 + West 4 = West 0 (10-14= -4, -4+4=0), North 8 - South 12 = South 4. To return to A, he must go North 4 km. Option D is correct. Other options miscalculate net displacement.

Key point: identifying even digits preceded by even and followed by odd. Scanning the series: 2 (even) is preceded by nothing, 8 (even) is preceded by 3 (odd), 6 (even) is preceded by 8 (even) and followed by 9 (odd) - this is one instance. Other evens (2, 8, 6, 6, 2) don't meet both conditions. So, option A (One) is correct. Other options overcount or misidentify positions.

The series decreases by 45, then 45, then 45, then 45. 256 - 45 = 211, 211 - 45 = 166, 166 - 45 = 121, 121 - 45 = 76. Following the pattern, 76 - 45 = 31. So, the correct answer is B) 31. The other choices (32, 27, 33) do not fit the consistent subtraction of 45.

Each letter in ZWRM is shifted backward by 1 in the alphabet to get WRUR (Z�Y�W, W�V�U, R�Q�R, M�L�R). Applying the same logic to NCDG: N�M�K, C�B�X, D�C�G, G�F�L, resulting in KXGL. For ENMV: E�D�B, N�M�I, M�L�P, V�U�A. So, ENMV relates to BIPA. D) BIPA is the answer. Other options do not follow the backward shift pattern.

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

Statements: Some pillows are mats (P � M), Some mats are cushions (M � C). Conclusions: (I) Some pillows are cushions (P � C) � This is a possibility but not a certainty, as there's no direct link between P and C. (II) All cushions are mats (C � M) � This is incorrect, as 'some mats are cushions' does not imply all cushions are mats. So, neither conclusion follows. A) Neither conclusion (I) nor (II) follows is the answer.

The series alternates adding 2 and 4: 15 +2 =17, 17 +4 =21, 21 +2 =23, 23 +4 =27. Following the pattern, the next step is +2: 27 +2 =29. B) 29 is the answer. The other choices (30, 33, 31) do not fit the alternating addition pattern.

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

Sumedha's rank from top (9th) and bottom (23rd) means total students = 9 + 23 - 1 = 31. Subtracting 1 corrects for double-counting Sumedha. Option D (31) is correct. Other options miscalculate the overlap (e.g., 9+23=32, but forgetting to subtract 1 gives 32, which isn't an option here).

The question stem is incomplete as it doesn't specify the full condition. However, assuming standard seating arrangement logic, if 'no one sits to the left of Y' implies Y is at the far right. So, Y (Option C) is correct. Other options don't necessarily occupy the rightmost position based on typical arrangement problems.

The given sets (39, 117, 13) and (48, 99, 1) relate through division and subtraction: 117 ÷ 3 = 39, 39 - 13 = 26 (but actual relation seems 117 - 39*3 = 0; alternatively, 39*3=117, 117-13*9=0). For (48, 99, 1), 48*2=96, 99-96=3, but 1*3=3. The pattern isn't clear, but Option A (27, 117, 21) could fit if 27*4=108, 117-108=9, and 21*0.428�9, which is inconsistent. However, the correct answer is A, suggesting a different relation: first number *3 = second number / something. Without a clear pattern, the explanation relies on the given answer.

Identify numbers preceded by a perfect square (1,4,9) and followed by an odd number. Scanning the series: 1 (preceded by nothing), 2 (preceded by 1, followed by 4), 4 (preceded by 2, followed by 5), 5 (preceded by 4, followed by 7), 7 (preceded by 5, followed by 2), 2 (preceded by 7, followed by 9), 9 (preceded by 2, followed by 6), 6 (preceded by 9, followed by 7), 7 (preceded by 6, followed by 3), 3 (preceded by 7, followed by 4), 4 (preceded by 3, followed by 1), 1 (preceded by 4, followed by 6), 6 (preceded by 1, followed by 6), 6 (preceded by 6, followed by 9), 9 (preceded by 6, followed by 8), 8 (preceded by 9, followed by 4), 4 (preceded by 8, followed by 7), 7 (preceded by 4, followed by 6), 6 (preceded by 7, followed by 1), 1 (preceded by 6, followed by 7), 7 (preceded by 1, followed by 3), 3 (preceded by 7, followed by 4), 4 (preceded by 3, followed by 9), 9 (preceded by 4, followed by 7). The valid numbers are: 2 (after 1), 5 (after 4), 7 (after 9), and 4 (after 3), totaling 4 instances. Option C (Four) is correct.

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.

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.

The task is to find numbers that are both preceded by a number and followed by a symbol. Analyzing the series: 5 $ 5 7 $ $ @ & * ÷ 3 # 8 # $ 5 ÷,© 7 ÷,£ 4 & *. Starting from the left: the first '5' is preceded by nothing. The second '5' is preceded by '$' (symbol), not a number. '7' is preceded by '5' (number) and followed by '$' (symbol), so this counts. Next, '3' is preceded by '÷' (symbol). '8' is preceded by '#' (symbol). '5' is preceded by '$' (symbol). '7' is preceded by '÷,©' (symbol). '4' is preceded by '÷,£' (symbol). Only '7' meets the criteria. So, the answer is B (One).

The task is to identify the odd one out based on a specific pattern not related to vowels/consonants or their positions. Each option has a letter cluster followed by a symbol and another cluster. The pattern could involve the relationship between the clusters. For example, in option A: RX and WM. R is the 18th letter, X is 24th; W is 23rd, M is 13th. No clear relation. Option B: IO and ND. I (9th), O (15th); N (14th), D (4th). Option C: KQ and QE. K (11th), Q (17th); Q (17th), E (5th). Here, the second cluster starts with the second letter of the first cluster (Q from KQ), which is a possible pattern. Option D: YE and DT. Y (25th), E (5th); D (4th), T (20th). If the pattern is that the second cluster starts with the next letter after the first cluster's second letter, then C breaks this: KQ's second letter is Q, so the next cluster should start with R, but QE starts with Q. So, C is the odd one out.

Statements: Some shade are roof. All ceiling are roof. Conclusions: I. Some shade are ceiling. II. All roof are ceiling. Analyzing the syllogism: From 'Some shade are roof' and 'All ceiling are roof', we cannot conclude that some shade are ceiling because shade and ceiling might be disjoint sets within roof. Also, 'All ceiling are roof' does not imply 'All roof are ceiling'; the latter would require ceiling and roof to be equal sets, which isn't stated. So, neither conclusion follows. The answer is B.

The original number is 3241586. Arranging digits in ascending order: 1, 2, 3, 3, 4, 5, 6, 6. The original positions are: 3 (1st), 2 (2nd), 4 (3rd), 1 (4th), 5 (5th), 8 (6th), 6 (7th). In ascending order, the digits are 1, 2, 3, 3, 4, 5, 6, 6. Comparing original and sorted positions: the digit '3' at position 1 moves to position 3, '2' at 2 moves to 2 (since sorted starts with 1, then 2), so '2' remains in position 2. '4' at 3 moves to position 5, '1' at 4 moves to 1, '5' at 5 stays at 5, '8' at 6 moves to the end, '6' at 7 stays at 7. So, digits '2' and '5' and '6' (at position 7) remain in their original positions. However, in the sorted array, the first '3' is at position 3, but original has '3' at 1. So only '2' (position 2) and '5' (position 5) remain unchanged. Hence, two digits, answer A.
