Explanation

To arrange the words in alphabetical order as they appear in a dictionary, we compare them letter by letter from left to right.

All four words begin with the prefix Cl.

Comparing the third letter of each word, i (Claim) has a, while the others have e. Since a comes before e, i (Claim) is the first word in the sequence.

For the remaining three words, comparing the fourth letter of the Cle- prefix shows that ii (Clearly) has a, while iii (Clerk) and iv (Clerical) have r. Since a comes before r, ii (Clearly) is the second word in the sequence.

To determine the order between the last two words, we compare the fifth letter of Cler-. The word iv (Clerical) has i, while iii (Clerk) has k. Since i comes before k in the alphabet, iv (Clerical) comes before iii (Clerk).

This yields the complete alphabetical order of i, ii, iv, iii.

Explanation

The letters of the given words are coded with specific symbols based on a direct letter-to-symbol substitution scheme.

From the coding of PEPPER as @#@@#! and AIM as ^?*, the symbol mapping for each individual letter is determined as follows: P is coded as @ E is coded as # R is coded as ! A is coded as I is coded as ? M is coded as *

By substituting these mapped symbols into the word PAMPER: The first letter P is @ The second letter A is The third letter M is * The fourth letter P is @ The fifth letter E is # The sixth letter R is !

Arranging these in order, PAMPER is written as @^*@#!.

Explanation

The sum of the numbers in each column is constant and equals 38. For the first column, 24 + 5 + 9 = 38; for the second column, 30 + 7 + 1 = 38; and for the third column, 19 + 18 + 1 = 38. Thus, the missing number is 1.

Explanation

Substituting the given symbols with their corresponding mathematical operators: 217 ÷ 7 - 3 + 2 × 7

According to the BODMAS rule, division and multiplication are performed first: 217 ÷ 7 = 31 2 × 7 = 14

Substituting these values back into the expression: 31 - 3 + 14

Performing the addition and subtraction: 28 + 14 = 42

Explanation

The given letter series contains 12 positions including the gaps: JK_MJ_LM_KL_.

By placing the letters L, K, J, and M sequentially from the option LKJM into the gaps, the series becomes: JKLMJKLMJKLM

This forms a continuous repeating pattern of the four-letter group JKLM repeated three times, which perfectly completes the series.

Explanation

Let Ankit's house be the central reference point. Since Ravi's house is to the west of Ankit's house, Ravi's position is to the left of Ankit's position. Since Lavi's house is to the north of Ankit's house, Lavi's position is directly above Ankit's position.

To find the direction of Lavi's house with respect to Ravi's house, we look from Ravi's position. Looking from Ravi's house towards Lavi's house requires looking upwards (North) and to the right (East). This combined direction is North-East.

Explanation

In the given matrices, letters are represented first by their row number and then by their column number. The word NAVY is coded as follows:

For N, the code 75 refers to row 7 and column 5 of Matrix-II.

For A, the code 00 refers to row 0 and column 0 of Matrix-I.

For V, the code 96 refers to row 9 and column 6 of Matrix-II.

For Y, the code 59 refers to row 5 and column 9 of Matrix-II.

Explanation

We can break down the statement made by the girl step-by-step:

First, my husband's mother-in-law refers to the girl's own mother.

Second, the only son of my husband's mother-in-law refers to the only son of the girl's mother, which is the girl's brother.

Third, married to the only son of my husband's mother-in-law means married to the girl's brother. This person is the girl's sister-in-law.

Fourth, the statement says that the woman's daughter-in-law is this sister-in-law who is married to the girl's brother. For the girl's brother's wife to be the woman's daughter-in-law, the woman must be the mother of the girl's brother.

Since the woman is the mother of the girl's brother, she is also the mother of the girl. Therefore, the girl is the daughter of the woman.

Explanation

Sachin Tendulkar is a globally renowned professional player associated with the sport of Cricket. Analogously, Roger Federer is a legendary professional player associated with the sport of Lawn Tennis, having won numerous Grand Slam titles.

Explanation

The relationship in the first pair TC : EV is obtained by adding 2 to the alphabetical position of each letter and then reversing their positions.

C is the 3rd letter, and 3 + 2 = 5, which is E. T is the 20th letter, and 20 + 2 = 22, which is V. This gives the letters E and V, which are written as EV.

Applying the same logic to NS: S is the 19th letter, and 19 + 2 = 21, which is U. N is the 14th letter, and 14 + 2 = 16, which is P. Reversing the order of these new letters gives UP.

Explanation

The pattern follows a constant numerical shift in the alphabetical positions of the letters, where A = 1, B = 2, and so on.

For the first pair, DR to KK: D (4) + 7 = K (11) R (18) - 7 = K (11)

Applying this same (+7, -7) pattern to LN: L (12) + 7 = S (19) N (14) - 7 = G (7)

This yields the letters SG.

Explanation

The relation followed in the analogy is based on the formula x³ - x², where x is the given number.

For the first pair: 5³ - 5² = 125 - 25 = 100

Applying the same logic to the second pair: 6³ - 6² = 216 - 36 = 180

Explanation

Pankaj Advani is an acclaimed Indian professional billiards and snooker player who has achieved numerous world championship titles in these cue sports, while the rest of the individuals listed are celebrated Indian field hockey players.

Explanation

The standard letter groups in this question follow a pattern where each consecutive letter decreases by 2 in its alphabetical position.

For the letter group XUS, the positions of the letters in the English alphabet are: X = 24 U = 21 S = 19

The difference between the first and second letter is 3 (24 - 21 = 3), and the difference between the second and third letter is 2 (21 - 19 = 2). Because this group does not follow the constant decrement of 2, it is the odd one out.

Explanation

The number 104 is the odd one out because it is not divisible by 9. The other numbers, 153, 261, and 108, are all multiples of 9. This is verified by the sum of their digits: 1 + 5 + 3 = 9, 2 + 6 + 1 = 9, and 1 + 0 + 8 = 9. The sum of the digits of 104 is 1 + 0 + 4 = 5, which is not divisible by 9.

Explanation

In the number 456, the digits are arranged in consecutive ascending order, where each digit increases by exactly one from left to right (4 → 5 → 6). In all other options, the digits are not arranged in consecutive ascending order.

Explanation

The given series represents the chronological stages of the formal educational qualification system. Matriculation, which represents secondary education, is followed by Intermediate, representing higher secondary education. After this comes Graduation, which represents a bachelor's degree. The next logical stage in this academic progression is a Post-graduate qualification, which represents a master's degree.

Explanation

The series is formed by two independent patterns for the first and second letters of each term.

For the first letters, the position increases by a constant value of 3: A (1) + 3 = D (4) D (4) + 3 = G (7) G (7) + 3 = J (10) J (10) + 3 = M (13)

For the second letters, the position increases by a decreasing sequence of integers (+6, +5, +4, +3): K (11) + 6 = Q (17) Q (17) + 5 = V (22) V (22) + 4 = Z (26) Z (26) + 3 = C (29, which wraps around the alphabet to position 3)

Combining the two letters gives the next term as MC.

Explanation

The series alternates between a two-letter term and a single-letter term. In this pattern, each single-letter term is the alphabetical middle letter of the preceding two-letter term.

For the first pair, the letters are S (19th letter) and Q (17th letter). The letter directly in the middle of them is R (18th letter).

For the second pair, the letters are X (24th letter) and V (22nd letter). The letter directly in the middle of them is W (23rd letter).

Following this pattern, for the third pair, the letters are I (9th letter) and K (11th letter). The letter directly in the middle of them is J (10th letter).

Explanation

The pattern of the series is that each term is obtained by adding the sum of its own digits to itself.

For the first term 19, the sum of its digits is 1 + 9 = 10. Adding this to 19 gives the next term 29.

For the second term 29, the sum of its digits is 2 + 9 = 11. Adding this to 29 gives the next term 40.

For the third term 40, the sum of its digits is 4 + 0 = 4. Adding this to 40 gives the next term 44.

Following this same logic, for the fourth term 44, the sum of its digits is 4 + 4 = 8. Adding 8 to 44 yields 52.

Explanation

By translating the statements into standard logical propositions, we get: All men are sinners. All saints are men.

Combining these two propositions, since the set of saints is entirely contained within the set of men, and the set of men is entirely contained within the set of sinners, it logically follows that the set of saints is entirely contained within the set of sinners. Therefore, all saints are sinners, which matches Conclusion I.

Explanation

From 27th February 2011 to 27th February 2012 is exactly 1 ordinary year of 365 days, because the leap day on 29th February 2012 is not included in this period.

365 days divided by 7 leaves a remainder of 1 odd day. Therefore, 27th February 2012 is Sunday + 1 day = Monday.

From 27th February 2012 to 1st March 2012, we count the remaining days in February 2012, which is a leap year and has 29 days: 28th February is Tuesday. 29th February is Wednesday. 1st March is Thursday.

Alternatively, the total number of days from 27th February 2011 to 1st March 2012 is 365 days (to 27th February 2012) + 2 days (remaining in February) + 1 day (1st March) = 368 days.

Dividing 368 by 7 gives 52 weeks and a remainder of 4 odd days. Adding 4 odd days to Sunday (Sunday + 4 days) results in Thursday.

Explanation

A frog is biologically classified under the class Amphibian. Similarly, a cobra is a venomous snake that belongs to the class Reptiles. The analogy represents the relationship between an animal and its biological class.

Explanation

To arrange the words in the alphabetical order as they appear in a dictionary, we compare them letter by letter from left to right.

All four words start with the prefix Acc. Comparing the fourth letter, Accompany has o while Accuse, Accustom, and Accumulation have u. Since o comes before u, Accompany (iv) is the first word in the sequence.

Next, comparing the remaining three words at the fifth letter, Accumulation has m while Accuse and Accustom have s. Since m comes before s, Accumulation (iii) is the second word in the sequence.

Finally, comparing Accuse and Accustom at the sixth letter, Accuse has e while Accustom has t. Since e comes before t, Accuse (i) comes before Accustom (ii).

This gives the complete alphabetical sequence as Accompany (iv), Accumulation (iii), Accuse (i), and Accustom (ii).

Explanation

The coding pattern shifts each letter of the 7-letter word forward by one position in the English alphabetical order, except for the middle (4th) letter, which remains unchanged:

C (+1) → D E (+1) → F R (+1) → S T (+0) → T A (+1) → B I (+1) → J N (+1) → O

Applying the same logic to CRICKET:

C (+1) → D R (+1) → S I (+1) → J C (+0) → C K (+1) → L E (+1) → F T (+1) → U

Explanation

The pattern followed in each column of the matrix is:

(First Row Number)² × Second Row Number = Third Row Number

Applying this logic to the first column: 7² × 2 = 49 × 2 = 98

Applying this logic to the third column: 5² × 3 = 25 × 3 = 75

Applying the same logic to the second column to find the missing number: 6² × 3 = 36 × 3 = 108

Explanation

According to the given mathematical operators, we substitute the symbols as follows: @ represents division (÷) represents multiplication (×) represents addition (+) % represents subtraction (-)

Substituting these operators into the given expression: 84 @ 12 # 3 24 % 35 = 84 ÷ 12 × 3 + 24 - 35

Applying the BODMAS rule: Step 1: Perform division 84 ÷ 12 = 7 The expression becomes: 7 × 3 + 24 - 35

Step 2: Perform multiplication 7 × 3 = 21 The expression becomes: 21 + 24 - 35

Step 3: Perform addition 21 + 24 = 45 The expression becomes: 45 - 35

Step 4: Perform subtraction 45 - 35 = 10

This yields the final value of 10.

Explanation

The given letter series consists of 18 elements. Dividing this series into two groups of 9 letters each gives: M _ P _ M _ R _ P | M _ P M _ R R _ P

By sequentially substituting the letters R, M, R, P, R, M, P into the gaps, we get: M R P M M R R P P | M R P M M R R P P

This forms a repeating 9-letter pattern. The pattern within each 9-letter block is composed of the sequence MRP followed by the same sequence with doubled letters: M R P + M M R R P P

Explanation

The actual direction of West is at 270°. The incorrectly aligned compass shows South-West (225°) for actual West, which represents a shift of 45° in the counter-clockwise direction.

Applying the same 45° counter-clockwise shift to the actual direction of North (360° or 0°) results in 315°, which corresponds to North-West.

Explanation

The representation of letters from the matrices is given in the row-first and column-second format. By examining the values in option C:

88 corresponds to the letter at Row 8 and Column 8 of Matrix-II, which is M. 65 corresponds to the letter at Row 6 and Column 5 of Matrix-II, which is O. 20 corresponds to the letter at Row 2 and Column 0 of Matrix-I, which is V. 24 corresponds to the letter at Row 2 and Column 4 of Matrix-I, which is E.

Combining these letters in sequence gives the word MOVE.

Explanation

Neha is the only girl of her father. This means her father has only one daughter, who is Neha.

Neha's father is the father-in-law of Pranav's brother. Since Neha is the only daughter, the person married to Neha must be Pranav's brother. Therefore, Pranav's brother is Neha's husband.

We are given that Pranav is Rajeev's nephew. Since Pranav and Neha's husband are brothers, Neha's husband is also Rajeev's nephew.

This makes Rajeev the uncle of Neha's husband. In standard family relationships, the uncle of one's husband is referred to as a father-in-law (or uncle-in-law).

Explanation

The position of each letter of the alphabet is represented by its standard numerical value where A = 1, B = 2, C = 3, and so on.

For the first pair, EFGH to LNPR, the transformation is based on adding consecutive integers starting from 7 to the position of each corresponding letter: E (5) + 7 = 12 (L) F (6) + 8 = 14 (N) G (7) + 9 = 16 (P) H (8) + 10 = 18 (R)

Applying this same logic of adding +7, +8, +9, and +10 to the letters of ABCD: A (1) + 7 = 8 (H) B (2) + 8 = 10 (J) C (3) + 9 = 12 (L) D (4) + 10 = 14 (N)

This yields HJLN.

Explanation

Opposite letters in the English alphabet are pairs of letters that are at the same distance from the beginning and the end. The sum of the positional values of these pairs is always 27.

In the first pair JS : QH: J is the 10th letter from the start, and Q is the 10th letter from the end (17th from the start, 10 + 17 = 27). S is the 19th letter from the start, and H is the 19th letter from the end (8th from the start, 19 + 8 = 27).

Applying the same logic to VW: V is the 22nd letter from the start, so its opposite is the 5th letter from the start, which is E (22 + 5 = 27). W is the 23rd letter from the start, so its opposite is the 4th letter from the start, which is D (23 + 4 = 27).

Explanation

The mathematical relation followed in this analogy is: x : 10 × (x + 1)

Applying this formula to the first term where x = 25: 25 : 10 × (25 + 1) = 10 × 26 = 260

Similarly, applying the same relation to the second term where x = 30: 30 : 10 × (30 + 1) = 10 × 31 = 310

Explanation

An airplane is a mode of air transportation, whereas the other vehicles operate exclusively on land.

Explanation

The letters in the groups FLR, KQW, and CIO follow a pattern where each subsequent letter is obtained by adding 6 to the alphabetical positional value of the previous letter. In FLR, the positions are 6, 12, and 18. In KQW, they are 11, 17, and 23. In CIO, they are 3, 9, and 15. The letter group PIB deviates from this pattern because its alphabetical positions are 16, 9, and 2, which decrease by 7.

Explanation

The sum of the digits of the number 1280 is 1 + 2 + 8 + 0 = 11, which is not divisible by 9. In contrast, the sum of the digits for all the other given numbers is 9, making them perfectly divisible by 9.

Explanation

The number 86 is not divisible by 17, whereas all other numbers in the set are multiples of 17.

Explanation

The terms in the series follow a constant addition pattern based on the alphabetical positions of the letters.

For the first letter of each pair: R is the 18th letter. Adding 8 gives Z, which is the 26th letter. Z (26) + 8 gives H, which is the 8th letter after wrapping around the alphabet. H (8) + 8 gives P, which is the 16th letter.

For the second letter of each pair: S is the 19th letter. Adding 8 gives A, which is the 1st letter after wrapping around. A (1) + 8 gives I, which is the 9th letter. I (9) + 8 gives Q, which is the 17th letter.

This produces the term PQ.

Explanation

The analogy represents the relationship between a specific geographical feature and its corresponding classification. The Pacific is a well-known ocean, making the category Ocean. Following the same pattern, the Nile is a major world river, which means its corresponding classification is River.

Explanation

The word DEMONSTRATE with 11 letters is divided into three parts of 5, 1, and 5 letters respectively: DEMON, S, and TRATE. The first and last parts are reversed, while the middle letter remains in its position, giving NOMED, S, and ETART, which combines to NOMEDSETART.

Applying the same pattern to the 7-letter word CORRUPT, it is divided into three parts of 3, 1, and 3 letters: COR, R, and UPT. Reversing the first and last parts while keeping the middle letter unchanged gives ROC, R, and TPU, which combines to ROCRTPU.

Explanation

The relationship is based on opposite letters in the English alphabet, where the sum of the numerical positions of opposite letter pairs is always 27.

In the first pair, the opposite letter of M (13) is N (27 - 13 = 14), and the opposite letter of N (14) is M (27 - 14 = 13), which gives NM.

Applying the same logic to JK: The opposite of J (10) is Q (27 - 10 = 17). The opposite of K (11) is P (27 - 11 = 16).

This yields the letters QP.

Explanation

The relationship between the first pair of numbers is based on the reversal of their digits. Reversing the digits of the number 85 yields 58.

Applying the same logic to the second pair, reversing the digits of the number 64 yields 46.

Explanation

The series consists of triplets of letters where the position of each letter in the alphabet decreases by a progressively increasing difference of 4, 5, and then 6.

For the first letter of each group: P (16), L (12), and G (7). The difference between the first two is 16 - 12 = 4, and between the second and third is 12 - 7 = 5. Following this pattern, the next difference must be 6. Subtracting 6 from 7 (G) gives 1, which corresponds to A.

For the second letter of each group: O (15), K (11), and F (6). The difference between the first two is 15 - 11 = 4, and between the second and third is 11 - 6 = 5. Following this pattern, the next difference must be 6. Subtracting 6 from 6 (F) wraps around the alphabet to 26, which corresponds to Z.

For the third letter of each group: N (14), J (10), and E (5). The difference between the first two is 14 - 10 = 4, and between the second and third is 10 - 5 = 5. Following this pattern, the next difference must be 6. Subtracting 6 from 5 (E) wraps around the alphabet to 25, which corresponds to Y.

Combining these letters gives AZY.

Explanation

The mantle is an internal structural layer of the Earth situated deep beneath the crust, whereas the other three represent the major outer environmental spheres or domains of the Earth's surface.

Explanation

In the letter pair WT, the alphabetical positions of the letters are W (23) and T (20), giving a difference of 3. In all other pairs, the letters are consecutive in reverse alphabetical order, having a difference of only 1 in their positional values.

Explanation

The number 124 is not a perfect cube, whereas the other options are perfect cubes of integers.

Explanation

In the other numbers, the product of the first and the last digit equals the number formed by the middle two digits. For 4308, the product of the first digit 4 and the last digit 8 is 32, whereas the middle two digits are 30.

Explanation

The series consists of alternating units of length from different measurement systems:

The first and third terms, Inch and Foot, are units of length in the Imperial system, where 1 foot = 12 inches.

The second and fourth terms, Decameter and Meter, are units of length in the Metric system, where 1 decameter = 10 meters.

Since Decameter is paired with the missing term in the metric system, the correct term to complete the series is Meter.

Explanation

The series follows a pattern where the difference between consecutive terms increases by 1 at each step.

8 - 5 = 3 12 - 8 = 4 17 - 12 = 5 23 - 17 = 6

Following this pattern, the difference between the next term and the current term must be 7. Adding 7 to the last term:

23 + 7 = 30
