Explanation

Jatin's paternal grandfather's wife is Jatin's paternal grandmother. The only daughter-in-law of Jatin's paternal grandmother must be the wife of Jatin's father, as she is the sole daughter-in-law in that generation. The wife of Jatin's father is Jatin's mother.

Explanation

The relationship in the first pair links a system of government to a country that practices it. India is famously the largest democracy in the world. Similarly, China is historically and currently defined as a communist state, governed continuously by the Chinese Communist Party since 1949.

Explanation

The relationship between the second pair of words, BIG and CLL, is determined by the addition of consecutive odd numbers to the alphabetical positions of their letters.

B + 1 = C (2 + 1 = 3) I + 3 = L (9 + 3 = 12) G + 5 = L (7 + 5 = 12)

Applying the same logic in reverse to find the first word from DDY:

D - 1 = C (4 - 1 = 3) D - 3 = A (4 - 3 = 1) Y - 5 = T (25 - 5 = 20)

Explanation

The relation in the second pair RMS : SLU is established by shifting the alphabetical positions of each letter.

The first letter increases by 1: R (18) + 1 = S (19) The second letter decreases by 1: M (13) - 1 = L (12) The third letter increases by 2: S (19) + 2 = U (21)

Using this same relationship in the first pair to find the unknown term from LLH, we perform the reverse operations:

The first letter is L (12) - 1 = K (11) The second letter is L (12) + 1 = M (13) The third letter is H (8) - 2 = F (6)

Explanation

The relationship between the numbers in the first pair is established by squaring the first number and multiplying the result by 10.

For the first pair: 11² × 10 = 121 × 10 = 1210

Applying the same logic to the second pair: 10² × 10 = 100 × 10 = 1000

Explanation

Trouser is worn on the lower part of the body to cover the legs, whereas all the other items are types of headwear worn on the head.

Explanation

The letter group FHA is the odd one out because it does not follow the constant letter-shifting pattern of subtracting 3 from the position of the first letter to get the second letter, and adding 7 to the second letter to get the third letter. For FHA, the positional values are F = 6, H = 8, and A = 1, where the difference from the first to second letter is plus 2 and from the second to third letter is minus 7, thereby deviating from the established pattern.

Explanation

The number 12 is the odd one out because it does not follow the mathematical pattern of n² - 1, where n is an odd integer. The other numbers in the set are all exactly 1 less than the square of an consecutive odd integers: 5² - 1 = 24, 7² - 1 = 48, and 9² - 1 = 80. For 12, the nearest values of this form are 3² - 1 = 8 and 4² - 1 = 15, which makes it the misfit in this group.

Explanation

The number 125 is a perfect cube (5³), while the other numbers in the group are perfect squares (12², 16², and 19²).

Explanation

The given series lists the United States Presidents who were assassinated while in office, arranged in chronological order of their assassination. Abraham Lincoln was assassinated in 1865, James Garfield in 1881, William McKinley in 1901, and John F. Kennedy in 1963.

Explanation

The given series can be analyzed by separating the first and second letters of each term.

The first letters follow the sequence A, C, E, ... Corresponding alphabetical positions: A = 1 C = 3 E = 5 The pattern is adding 2 to each successive position. The next position is 5 + 2 = 7, which corresponds to G.

The second letters follow the sequence K, O, S, ... Corresponding alphabetical positions: K = 11 O = 15 S = 19 The pattern is adding 4 to each successive position. The next position is 19 + 4 = 23, which corresponds to W.

Combining these two gives the next term in the series as GW.

Explanation

The series is formed by adding 5 to the alphabetical position of each letter in the preceding term.

The first letter of each term increases by 5: C (3rd) to H (8th), then to M (13th), and finally to R (18th).

The second letter of each term increases by 5: D (4th) to I (9th), then to N (14th), and finally to S (19th).

The third letter of each term increases by 5: E (5th) to J (10th), then to O (15th), and finally to T (20th).

This logic systematically produces the letters R, S, and T in order.

Explanation

The given series is generated by multiplying each term by 2 and then subtracting consecutive integers starting from 0:

3 × 2 - 0 = 6 6 × 2 - 1 = 11 11 × 2 - 2 = 20 20 × 2 - 3 = 37

Alternatively, the pattern can be observed through the difference between consecutive terms:

6 - 3 = 3 11 - 6 = 5 20 - 11 = 9

The differences between these successive differences are:

5 - 3 = 2 9 - 5 = 4

Since these second-level differences are successive powers of 2 (2¹ = 2, 2² = 4), the next difference of differences must be 2³ = 8.

This means the next term-to-term difference is 9 + 8 = 17. Adding this to the last term gives 20 + 17 = 37.

Explanation

By translating the statements into set theory: Let D represent the set of dogs, B represent the set of bullocks, and G represent the set of goats.

The first statement, All dogs are bullocks, means that the set of dogs is a subset of the set of bullocks (D ⊆ B). The second statement, All bullocks are goats, means that the set of bullocks is a subset of the set of goats (B ⊆ G).

Applying the transitive property of subsets, if D ⊆ B and B ⊆ G, then D ⊆ G. This mathematically proves that all dogs are goats. Therefore, Conclusion I logically follows from the given premises.

Explanation

The total weight of the clothes is 10 kg. The laundry charges are split into the rate for the first kilogram and the rate for the remaining kilograms.

For the first 1 kg, the charge is Rs. 150.

The remaining weight of the clothes is 10 - 1 = 9 kg. At a rate of Rs. 50 for every kilogram that follows, the cost for the remaining weight is 9 × 50 = Rs. 450.

The total money Sumit pays for the laundry service is the sum of these two charges: Total Cost = 150 + 450 = Rs. 600.

Explanation

To arrange the words in the order they occur in a dictionary, they must be sorted alphabetically by comparing their letters from left to right.

Comparing the second letters of all four words, Latitude, Laugh, and Latent have the letter a, while Longitude has the letter o. Since a comes before o, Longitude (ii) is placed last.

Next, comparing the third letters of Latitude, Laugh, and Latent, we see that Latitude and Latent have the letter t, while Laugh has the letter u. Since t comes before u, Laugh (iii) is placed after the other two.

Finally, comparing the fourth letters of Latent and Latitude, Latent has the letter e and Latitude has the letter i. Since e comes before i, Latent (iv) comes before Latitude (i).

Combining these steps gives the correct alphabetical sequence: Latent (iv), Latitude (i), Laugh (iii), Longitude (ii).

Explanation

Each letter is represented by a unique symbol based on its position in the given words.

From the word ANT which is written as # | !: The letter A is coded as # The letter N is coded as | The letter T is coded as !

From the word SIGHT which is written as @?*: The letter S is coded as @ The letter I is coded as ? The letter G is coded as *

By substituting the corresponding symbols for the letters in the word NIGHT: N is replaced by | I is replaced by ? G is replaced by * T is replaced by !

This gives the sequence | ?*!.

Explanation

By converting the letters in each column to their numerical alphabetical positions where A = 1, B = 2, C = 3, and so on, the sum of the letters in the first and second rows of each column equals the letter in the third row.

For the first column, B (2) + E (5) = G (7).

For the second column, J (10) + K (11) = U (21).

Applying this column-wise pattern to the third column, I (9) + B (2) = 11, which corresponds to the letter K.

Explanation

Replacing the letter codes with their corresponding mathematical operators gives:

294 B 7 A 40 C 33 D 11 = 294 ÷ 7 - 40 + 33 × 11

According to the BODMAS rule, division and multiplication are performed first, followed by addition and subtraction.

Performing the division: 294 ÷ 7 = 42

Performing the multiplication: 33 × 11 = 363

Substituting these values back into the expression: 42 - 40 + 363

Performing the remaining subtraction and addition: 42 - 40 = 2 2 + 363 = 365

Explanation

By placing the letters from option B (YXZY) sequentially in the gaps of the given series, the following sequence is formed:

X Y Z X X Y Y Z Z X Y Z

This completed series can be divided into three logical clusters:

XYZ / XXYYZZ / XYZ

In this pattern, the base sequence XYZ is placed at the beginning and the end, while each letter in the sequence is doubled (XXYYZZ) in the middle cluster. This successfully completes the letter series.

Explanation

The initial direction of the girl is East.

First, she turns 45° in the anticlockwise direction, which points her towards the North-East direction.

Next, she turns 180° in the clockwise direction. A turn of 180° in any direction aligns a person with the exact opposite of their current direction. Since she is facing North-East, turning 180° points her in the opposite direction, which is South-West.

Explanation

The letters of the word CARGO are represented by the row number followed by the column number.

For C, row 7 and column 8 in Matrix-II corresponds to the letter C, giving 78.

For A, row 1 and column 0 in Matrix-I corresponds to the letter A, giving 10.

For R, row 5 and column 7 in Matrix-II corresponds to the letter R, giving 57.

For G, row 2 and column 1 in Matrix-I corresponds to the letter G, giving 21.

For O, row 9 and column 5 in Matrix-II corresponds to the letter O, giving 95.

Explanation

The only daughter of Amar's maternal grandfather is Amar's mother. Since the man's wife is the only daughter of Amar's maternal grandfather, the man's wife is Amar's mother. Therefore, the man is the husband of Amar's mother, which makes him Amar's father.

Explanation

The given analogy represents a provider-recipient relationship. A doctor provides medical treatment and care to a patient, who is the recipient of those services. In the same manner, a shopkeeper sells goods or services to a customer, who is the recipient or buyer in that commercial transaction.

Explanation

The letters of the second term are obtained by shifting the letters of the first term forward by 2 positions in the alphabetical order.

E + 2 = G F + 2 = H

Applying the same relationship to the third term:

I + 2 = K J + 2 = L

Explanation

In the first group AE : FJ, the alphabetical positions of the letters are increased by 5: A (1) + 5 = F (6) E (5) + 5 = J (10)

Applying the same logic to find the pair that precedes PT: P (16) - 5 = K (11) T (20) - 5 = O (15)

This gives the letters KO.

Explanation

In the first pair of numbers, the second number is obtained by multiplying the individual digits of the first number: 9 × 6 = 54

Applying the same logic to the second pair: 8 × 9 = 72

Explanation

The letter pair AD contains the consonant D, whereas the other pairs consist entirely of vowels.

Explanation

The number 1 is not a prime number, whereas all other numbers in the set are prime numbers. A prime number is a natural number greater than 1 that has exactly two distinct positive divisors: 1 and itself. Since 1 has only one positive divisor, it is classified as neither prime nor composite.

Explanation

The pattern among the numbers is that the square of the first digit is represented by the last two digits of the number. For 745, the square of the first digit is 7² = 49, which is not equal to the remaining digits 45, making it the odd one out.

Explanation

The given series represents the sequential stages of the nitrogen cycle, which is the biogeochemical process through which nitrogen is converted into multiple chemical forms as it circulates among atmospheric, terrestrial, and marine ecosystems. The cycle begins with nitrogen fixation, converting atmospheric nitrogen into ammonia. This is followed by ammonification, where organic nitrogen is converted back into ammonia. Next, nitrification occurs, in which ammonia is oxidized into nitrites and subsequently into nitrates. The final major stage of the cycle is denitrification, where anaerobic bacteria convert nitrates back into nitrogen gas, releasing it back into the atmosphere and completing the biogeochemical loop.

Explanation

Each letter in the terms of the series is obtained by adding 4 to the alphabetical position of the corresponding letter in the previous term.

For the first letter, C is the 3rd letter, G is the 7th, and K is the 11th. Adding 4 to K gives the 15th letter, which is O.

For the second letter, E is the 5th letter, I is the 9th, and M is the 13th. Adding 4 to M gives the 17th letter, which is Q.

For the third letter, A is the 1st letter, E is the 5th, and I is the 9th. Adding 4 to I gives the 13th letter, which is M.

Combining these letters yields the next term of the series, which is OQM.

Explanation

The given series alternates between two distinct patterns.

The terms in the odd positions (1st, 3rd, 5th) are CD, GH, and KL. In this pattern, the alphabetical positions of both letters increase by 4 from one term to the next: C (3) to G (7) to K (11) D (4) to H (8) to L (12)

The terms in the even positions (2nd, 4th, 6th) are XW, TS, and the missing term. In this pattern, the alphabetical positions of both letters decrease by 4 from one term to the next: X (24) to T (20) to P (16) W (23) to S (19) to O (15)

Combining the letters P and O gives the next term.

Explanation

The differences between consecutive terms of the given series follow a specific pattern:

26 - 9 = 17 60 - 26 = 34 111 - 60 = 51

The differences are successive multiples of 17, which are 17 × 1, 17 × 2, and 17 × 3. Following this pattern, the next difference must be 17 × 4 = 68.

Adding 68 to the last term: 111 + 68 = 179

Explanation

From the first statement, the set of dogs is entirely contained within the set of rats. The second statement indicates that there is an overlap between the set of rats and the set of lizards. Since this overlapping region of rats and lizards does not necessarily have to intersect with the set of dogs, no definite relation can be established between dogs and lizards. Therefore, neither the conclusion that some dogs are lizards nor the conclusion that some lizards are dogs definitely follows.

Explanation

To arrange the words in alphabetical dictionary order, we compare their letters from left to right.

All four words begin with the letters Ge. Comparing the third letters, Genetic (iv) has n, Germination (ii) and Geriatric (iii) both have r, and Gesture (i) has s. Since n comes before r, and r comes before s, Genetic (iv) is the first word and Gesture (i) is the last word.

To determine the order between Germination (ii) and Geriatric (iii), we compare their fourth letters, which are m and i respectively. Since i comes before m, Geriatric (iii) precedes Germination (ii).

The resulting correct alphabetical sequence of the words is iv, iii, ii, i.

Explanation

The coding pattern divides the six-letter word into two equal halves of three letters each. The letters in the first half are shifted one step backward (-1) in the alphabetical order, while the letters in the second half are shifted one step forward (+1).

Applying this logic to CANADA: C - 1 = B A - 1 = Z N - 1 = M A + 1 = B D + 1 = E A + 1 = B This gives BZMBEB.

Applying the same logic to SYDNEY: S - 1 = R Y - 1 = X D - 1 = C N + 1 = O E + 1 = F Y + 1 = Z This gives RXCOFZ.

Explanation

In each row, the letter in the middle column is determined by the absolute difference between the numbers in the first and third columns. Let this absolute difference be d. The corresponding numerical position of the middle letter in the English alphabet, where A = 1, B = 2, and so on, is given by the formula:

Position = 4 + 2ᵈ

For the first row, the outer numbers are 13 and 14. The absolute difference is d = 14 - 13 = 1. Applying the formula, the alphabetical position is 4 + 2¹ = 6, which corresponds to the letter F.

For the third row, the outer numbers are 7 and 9. The absolute difference is d = 9 - 7 = 2. Applying the formula, the alphabetical position is 4 + 2² = 8, which corresponds to the letter H.

For the second row, the outer numbers are 6 and 3. The absolute difference is d = 6 - 3 = 3. Applying the formula, the alphabetical position is 4 + 2³ = 12, which corresponds to the letter L.

Explanation

The series is formed by alternating between the four-letter group pqrs and its reverse srqp:

pqrs | srqp | pqrs

When we align this pattern with the given series: Pattern: p q r s s r q p p q r s Given: p _ r _ s _ q _ p _ r s

Sequentially filling the five gaps with the letters from qsrpq completes the series: First gap gets q Second gap gets s Third gap gets r Fourth gap gets p Fifth gap gets q

This successfully completes the symmetric pattern pqrs srqp pqrs.

Explanation

The movement of Rohan forms a right-angled triangle where the horizontal movement is 5 km towards the west and the vertical movement after the left turn is 12 km towards the south.

The shortest distance between his initial position and final position is represented by the hypotenuse of this right-angled triangle. According to Pythagoras' theorem, the hypotenuse is calculated as:

Shortest distance = √(5² + 12²) = √(25 + 144) = √169 = 13 km

This represents a standard Pythagorean triplet where the sides 5, 12, and 13 satisfy the theorem.

Explanation

To represent the word TERM, each letter is coded first by its row number and then by its column number.

For the first letter T, from Matrix-I, the letter at row 2 and column 1 is T, giving the code 21.

For the second letter E, from Matrix-II, the letter at row 7 and column 7 is E, giving the code 77.

For the third letter R, from Matrix-I, the letter at row 3 and column 3 is R, giving the code 33.

For the fourth letter M, from Matrix-II, the letter at row 7 and column 6 is M, giving the code 76.

Combining these codes sequentially gives 21, 77, 33, 76.

Explanation

The relationship in the analogy is based on a famous historical monument and its geographical location. The Taj Mahal is a renowned monument located in the city of Agra. Similarly, the Old Fort, historically known as Purana Qila, is a major historical fort located in Delhi.

Explanation

The coding pattern splits the seven-letter word into three parts: the first three letters, the middle letter, and the last three letters.

For the first three letters of MYANMAR (M-Y-A), each letter is shifted forward by one position (+1) to get N-Z-B. The middle letter (N) remains unchanged to get N. For the last three letters (M-A-R), each letter is shifted backward by one position (-1) to get L-Z-Q.

Applying this same logic to BRITAIN: The first three letters (B-R-I) are shifted forward by one position (+1) to become C-S-J. The middle letter (T) remains unchanged to become T. The last three letters (A-I-N) are shifted backward by one position (-1) to become Z-H-M.

Combining these parts results in CSJTZHM.

Explanation

The logic of the analogy is based on multiplying the numerical positions of the letters in the English alphabetical order by 2.

In the first pair EM : JZ, the numerical position of E is 5, and multiplying by 2 yields 10, which corresponds to J. The numerical position of M is 13, and multiplying by 2 yields 26, which corresponds to Z.

Applying this pattern to the second pair KL, the numerical position of K is 11, and multiplying by 2 yields 22, which corresponds to V. The numerical position of L is 12, and multiplying by 2 yields 24, which corresponds to X.

Explanation

The relationship is based on multiplying the individual digits of the first number to obtain the second number.

For 79: 7 × 9 = 63

Applying the same logic to 54: 5 × 4 = 20

Explanation

The Indian Air Force is a component of the Indian Armed Forces and functions under the administrative control of the Ministry of Defence. It is primarily tasked with securing Indian airspace and conducting aerial warfare during conflicts. This distinct organizational structure under the Ministry of Defence sets it apart from domestic security forces that operate under the Ministry of Home Affairs.

Explanation

The pair BX does not consist of opposite letters in the alphabetical series. In the standard English alphabet, opposite letters are pairs whose positional values from the start and end of the alphabet sum to 27. The letters B and X have alphabetical positions of 2 and 24 respectively, which sum to 26, unlike standard opposite pairs such as B and Y. This makes BX the odd pair.

Explanation

The sum of the digits of 9113 is 14, which is an even number, calculated as 9 + 1 + 1 + 3 = 14. For the remaining numbers, the sum of their digits yields an odd number: 8 + 1 + 7 + 9 = 25, 7 + 1 + 4 + 7 = 19, and 8 + 1 + 3 + 5 = 17.

Explanation

The sum of the digits of 4313 is 11, which is an odd number: 4 + 3 + 1 + 3 = 11

In contrast, the sum of the digits for each of the other numbers is an even number: 5 + 4 + 3 + 4 = 16 8 + 7 + 2 + 3 = 20 3 + 6 + 7 + 4 = 20

Explanation

The given series represents the most spoken languages in India ranked in descending order based on the number of native speakers according to the Census of India. Hindi is the most spoken language, followed by Bengali as the second most spoken, Telugu as the third, Marathi as the fourth, and Tamil as the fifth. Thus, Bengali completes the sequential order of the series.
