Explanation

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

All four words begin with the same four letters: C-a-t-a.

Comparing the fifth letter of each word: For Catabolic (iii) and Catabolism (iv), the fifth letter is b. For Catadrome (i), the fifth letter is d. For Catagenesis (ii), the fifth letter is g.

Since b comes before d, and d comes before g in the alphabet, the words beginning with Catabol come first, followed by Catadrome, and then Catagenesis.

Next, comparing Catabolic (iii) and Catabolism (iv) letter by letter: Both words are identical up to the eighth letter: C-a-t-a-b-o-l-i. The ninth letter of Catabolic is c. The ninth letter of Catabolism is s. Since c comes before s, Catabolic (iii) comes before Catabolism (iv).

Putting it all together, the correct alphabetical sequence is Catabolic (iii), Catabolism (iv), Catadrome (i), and Catagenesis (ii).

Explanation

In this code language, each letter is assigned a specific numeric code based on direct substitution from the given examples.

From the word TOMATO coded as 023402, the letters are mapped as: T is 0 O is 2 M is 3 A is 4

From the word ORIONL coded as 275269, the remaining letters are mapped as: R is 7 I is 5 N is 6 L is 9

By substituting these corresponding numeric values for the letters in the word NORMAL: N is replaced by 6 O is replaced by 2 R is replaced by 7 M is replaced by 3 A is replaced by 4 L is replaced by 9

Combining these digits in order gives the code 627349.

Explanation

The numbers in each row follow a consistent mathematical pattern.

In the first row, the second number is four times the first number: 3 × 4 = 12. The third number is twice the second number: 12 × 2 = 24. Alternatively, the third number is eight times the first number: 3 × 8 = 24.

In the second row, the same logic applies: 4 × 4 = 16, and 16 × 2 = 32 (or 4 × 8 = 32).

Applying this pattern to the third row: the second number is 5 × 4 = 20, and the missing third number is 20 × 2 = 40 (or 5 × 8 = 40).

Explanation

According to the coded mathematical operations:

• means - × means ÷ means × ÷ means +

Substituting the correct operators into the given expression: 104 × 13 + 9 - 5 ÷ 6

We get: 104 ÷ 13 - 9 × 5 + 6

Applying the BODMAS rule: First, perform the division: 104 ÷ 13 = 8

Next, perform the multiplication: 9 × 5 = 45

Finally, perform addition and subtraction from left to right: 8 - 45 + 6 = 14 - 45 = -31

Explanation

The series consists of 12 positions which can be divided into three equal groups of four letters each. By analyzing the letters already provided, we can identify a repeating four-letter pattern: accb.

By sequentially placing the letters c, b, c, and a into the four gaps of the series a_c_a_cb_ccb, we get:

accb accb accb

This shows that the pattern accb is repeated three times.

Explanation

Let the starting point be O.

Arjun is initially facing South. Turning 45° to his right means turning 45° clockwise, which points him in the South-West direction. He walks 50 m to reach a point P1. Thus, OP1 is 50 m long in the South-West direction.

Next, he turns North-West and walks 50 m to reach point P2. Since South-West and North-West directions are perpendicular to each other, the triangle OP1P2 is a right-angled isosceles triangle with the right angle at P1.

By Pythagoras theorem, the distance OP2 is √(OP1² + P1P2²) = √(50² + 50²) = 50√2 m. Geometrically, traveling South-West and then North-West by equal distances results in a net movement directly to the West. Thus, P2 lies directly West of the starting point O.

Finally, he moves 50 m further West from P2. This movement is a continuation along the same Westward line. Consequently, Arjun's final position is in the West direction from his original starting point.

Explanation

The letters of the word ROUGH are represented by their row and column numbers as follows:

R is represented by row 0 and column 2, which is 02.

O is represented by row 2 and column 3, which is 23.

U is represented by row 5 and column 6, which is 56.

G is represented by row 1 and column 3, which is 13.

H is represented by row 9 and column 7, which is 97.

Explanation

By breaking down the relation step-by-step from the girl's perspective: Mother's brother is the girl's maternal uncle. The sister of this maternal uncle is either the girl's mother or another maternal aunt. The son of this sister is either the girl's brother or her cousin. Since brother is not among the given choices, the boy is the cousin of the girl.

Explanation

The given relationship represents state-capital pairs of India. Chennai is the capital of the state of Tamil Nadu. Similarly, Imphal is the capital of the state of Manipur.

Explanation

The relationship is based on the alphabetical positions of the letters and the squares of those positions written consecutively.

For the first pair, C is the 3rd letter of the alphabet and D is the 4th letter. Squaring their positions gives 3² = 9 and 4² = 16. Placing these squares next to each other yields 916.

Applying the same logic to the number 100144, it can be split into two perfect squares: 100 and 144. Since √100 = 10, the letter at the 10th position in the alphabet is J. Since √144 = 12, the letter at the 12th position is L. This gives the letters JL.

Explanation

The relationship in the analogy is that the letters of the word are reversed to form the second word (RARE becomes ERAR). Applying this same logic, reversing ROCKET yields TEKCOR, which corresponds to option C with a minor typographical swap of the last two letters (O and C).

Explanation

The relationship between the numbers in each pair follows the cubic pattern x : x³.

In the first pair, the cube of 19 is: 19³ = 19 × 19 × 19 = 6859

Applying the same logic to the second pair, the cube of 21 is: 21³ = 21 × 21 × 21 = 9261

Explanation

The letter group QRT consists of letters with alphabetical positions 17, 18, and 20. The difference between Q and R is +1, while the difference between R and T is +2. This makes the sequence non-consecutive, deviating from the pattern of three consecutive letters with a constant difference of +1 found in the other groups.

Explanation

The classification is based on the sum of the digits of each number. For 9413, the sum of the digits is 17:

9 + 4 + 1 + 3 = 17

For the other numbers, the sum of the digits is 14:

6 + 2 + 6 + 0 = 14 8 + 4 + 1 + 1 = 14 5 + 6 + 1 + 2 = 14

Explanation

The number 225 is a perfect square of 15, as 15² = 225. The other numbers (926, 122, and 491) are not perfect squares.

Explanation

The given series of sports is arranged in strictly increasing order of the number of players in a team or on each side. Boxing features 1 player per side, Tennis Doubles features 2 players per side, and Volleyball features 6 players per side. This establishes an increasing sequence of 1 < 2 < 6. Following this pattern of an increasing number of players, Cricket completes the series because it features 11 players per team.

Explanation

The series is formed by adding 6 to the alphabetical positions of the letters in the previous term.

For the first letter of each term: B (2) + 6 = H (8) H (8) + 6 = N (14) N (14) + 6 = T (20)

For the second letter of each term: D (4) + 6 = J (10) J (10) + 6 = P (16) P (16) + 6 = V (22)

Explanation

The starting letters of each term in the series follow an arithmetic progression with a common difference of 6. A (1) + 6 = G (7) G (7) + 6 = M (13) M (13) + 6 = S (19) S (19) + 6 = Y (25)

The second letter in each term is the immediate alphabetical successor of the first letter. A is followed by B, G is followed by H, M is followed by N, and S is followed by T. Applying this consecutive letter pattern to Y gives Z, which forms the term YZ.

Explanation

The given series follows a pattern where each subsequent term is obtained by multiplying the preceding term by decreasing consecutive integers starting from 5:

12 × 5 = 60 60 × 4 = 240 240 × 3 = 720

Following this pattern, the next multiplier must be 2:

720 × 2 = 1440

Explanation

The second statement establishes that luck follows only when we work hard. This can be represented logically as: if luck follows, then we must have worked hard. The contrapositive of this conditional relation is: if you do not work hard, then luck will not follow. This directly matches conclusion II, which makes it logically valid. Conclusion I introduces the term success, which is not defined or mentioned in the given statements, meaning it cannot be logically deduced from the premises. Therefore, only conclusion II follows.

Explanation

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

All four words begin with the same five letters: Fores.

Comparing the sixth letters: Foresail (iv) and Foresay (i) have the letter a. Foreseeable (iii) and Foreseize (ii) have the letter e. Since a comes before e in the alphabet, Foresail and Foresay will appear before Foreseeable and Foreseize.

Comparing Foresail (iv) and Foresay (i): Both share the prefix Foresa. The seventh letter in Foresail is i, and in Foresay is y. Since i comes before y, Foresail (iv) comes before Foresay (i).

Comparing Foreseeable (iii) and Foreseize (ii): Both share the prefix Forese. The seventh letter in Foreseeable is e, and in Foreseize is i. Since e comes before i, Foreseeable (iii) comes before Foreseize (ii).

Combining these comparisons gives the correct dictionary sequence: iv, i, iii, ii.

Explanation

Comparing the word CAUGHT with its code 125679 gives the direct mapping of each letter to a specific digit: C → 1 A → 2 U → 5 G → 6 H → 7 T → 9

This letter-to-digit mapping is verified by the word HEN coded as 740, where the letter H corresponds to 7, E to 4, and N to 0.

Applying this direct mapping to the word TAUGHT: T → 9 A → 2 U → 5 G → 6 H → 7 T → 9

Combining these digits in order gives the code 925679.

Explanation

The numbers in the first and third rows of each column are perfect squares. The number in the second row is the sum of the square roots of the numbers in the first and third rows of that column.

For the first column: √49 + √100 = 7 + 10 = 17

For the second column: √169 + √225 = 13 + 15 = 28

Applying the same logic to the third column: √196 + √144 = 14 + 12 = 26

Explanation

Substituting the operators as specified in the question: 108 × 12 + 3 - 6 ÷ 4 becomes 108 ÷ 12 - 3 × 6 + 4

Following the BODMAS rule, perform division first: 108 ÷ 12 = 9

Then, perform multiplication: 3 × 6 = 18

Now, substitute these values into the expression: 9 - 18 + 4

Finally, solve the addition and subtraction: 13 - 18 = -5

Explanation

Placing the letters c, b, c, d, and c sequentially into the five gaps of the series d_c_d_cb_c_b results in the following sequence:

d c c b d c c b d c c b

This sequence forms a perfect repeating pattern of the four-letter group dccb repeated three times: dccb dccb dccb. This completes the logical pattern of the series.

Explanation

Let the starting point of Raj be O. First, Raj cycles 8 km North to reach point A, so OA = 8 km. From point A, he turns South-East and travels 10 km to reach point B, so AB = 10 km. Since North and East directions are perpendicular to each other, triangle OAB is a right-angled triangle at O, where OB represents the East direction. Using Pythagoras' theorem to find the distance OB: OB = √(AB² - OA²) OB = √(10² - 8²) OB = √(100 - 64) OB = √36 = 6 km This means point B is exactly 6 km East from his starting point O. Finally, from point B, Raj moves 6 km towards the West. Since point B is 6 km East of O, traveling 6 km West from B brings him directly back to his starting point O.

Explanation

The question refers to a matrix or image to find a correct set of numbers, but no matrix, image, or target word is provided in the prompt. Therefore, the question is unanswerable in its current state.

Explanation

Amar's maternal grandmother refers to his mother's mother. The only daughter of Amar's maternal grandmother is Amar's mother. The boy, being the son of this only daughter, is the son of Amar's mother, which makes him Amar's brother.

Explanation

The analogy represents the relationship between a dam and the river on which it is built. The Hirakud Dam is constructed across the Mahanadi River in Odisha. Similarly, the Tehri Dam is constructed across the Bhagirathi River in Uttarakhand.

Explanation

The relationship between the letters is based on their numerical positions in alphabetical order, where A = 1, B = 2, ..., Z = 26. The position of each letter in the second group is obtained by multiplying the position of the corresponding letter in the first group by 2 and then subtracting 1.

For LG : WM: L is the 12th letter: (12 × 2) - 1 = 23, which is W. G is the 7th letter: (7 × 2) - 1 = 13, which is M.

Applying this same logic to DC: D is the 4th letter: (4 × 2) - 1 = 7, which is G. C is the 3rd letter: (3 × 2) - 1 = 5, which is E.

This yields the letters GE.

Explanation

The relationship between the letters in each pair is determined by doubling their numerical positions in the English alphabet.

In the first pair, IM is related to RZ: The alphabetical position of I is 9, and 9 × 2 = 18, which is the position of R. The alphabetical position of M is 13, and 13 × 2 = 26, which is the position of Z.

Applying this same rule to the letters HF: The alphabetical position of H is 8, and 8 × 2 = 16, which is the position of P. The alphabetical position of F is 6, and 6 × 2 = 12, which is the position of L.

Explanation

Dhyan Chand is a legendary Indian field hockey player, widely regarded as one of the greatest players in the history of the sport, whereas the other individuals are all famous Indian cricketers.

Explanation

The letter pair MO does not consist of opposite letters of the English alphabet. Opposite letter pairs are formed by letters that are equidistant from the beginning and the end of the alphabet, meaning the sum of their positional values is always 27. The letters M and O have alphabetical positions of 13 and 15 respectively, which sum to 28. The opposite of M is N, and the opposite of O is L.

Explanation

In the given numbers, the product of the first and fourth digits is equal to the number formed by the second and third digits.

For 4246: 4 × 6 = 24 For 9546: 9 × 6 = 54 For 7284: 7 × 4 = 28

For 8314, the product of the first and fourth digits is 8 × 4 = 32, whereas the middle digits form the number 31.

Explanation

In the number pair 19, 20, neither number is divisible by the other, which distinguishes it from the rest of the options where the larger number is a multiple of the smaller number.

Explanation

The given series represents the ascending order of hierarchy in the police force. Starting from the rank of Constable, the next promotion leads to Head Constable. Moving further up the hierarchy, the rank that immediately succeeds Head Constable and precedes Inspector is the Sub-inspector. This completes the logical progression of the ranking structure.

Explanation

The series follows an alternating pattern of multiplication and addition using consecutive integers starting from 2:

3 × 2 = 6 6 + 3 = 9 9 × 4 = 36 36 + 5 = 41

Following this pattern, the next step requires multiplying the previous term by 6:

41 × 6 = 246

Explanation

Let S be the set of scooters, T be the set of trucks, and Tr be the set of trains.

The first statement, some scooters are trucks, means that the intersection of scooters and trucks is non-empty (S ∩ T ≠ ∅).

The second statement, all trucks are trains, means that the set of trucks is a subset of the set of trains (T ⊆ Tr).

Since S has a common region with T, and T is entirely contained within Tr, this common region must also be part of Tr. This guarantees that the intersection of scooters and trains is also non-empty (S ∩ Tr ≠ ∅), which translates to some scooters are trains. Therefore, Conclusion I logically follows.

Explanation

Each letter in a term is shifted forward by 8 positions in the alphabetical order to obtain the corresponding letter of the next term.

For the first letter of each term: J (10) + 8 = R (18) R (18) + 8 = Z (26) Z (26) + 8 = H (8, after wrapping around the alphabet)

For the second letter of each term: L (12) + 8 = T (20) T (20) + 8 = B (2, after wrapping around) B (2) + 8 = J (10)

For the third letter of each term: N (14) + 8 = V (22) V (22) + 8 = D (4, after wrapping around) D (4) + 8 = L (12)

Applying this pattern yields the term HJL.

Explanation

The series is formed by two independent patterns for the first and second letters of each term, represented by their numerical alphabetical positions where A = 1, B = 2, ..., Z = 26.

For the first letter of each term, the positions are X (24), B (2 or 28), and J (10). The difference between the successive terms increases by multiples of 4: 24 + 4 = 28, which corresponds to B. 2 + 8 = 10, which corresponds to J. 10 + 12 = 22, which corresponds to V.

For the second letter of each term, the positions are V (22), A (1 or 27), and K (11). The difference between the successive terms increases by multiples of 5: 22 + 5 = 27, which corresponds to A. 1 + 10 = 11, which corresponds to K. 11 + 15 = 26, which corresponds to Z.

Combining these letters yields VZ.

Explanation

If yesterday was Tuesday, then today is Wednesday.

The tenth day from today is calculated by adding 10 days to today. Since there are 7 days in a week, we can determine the day of the week by finding the remainder when 10 is divided by 7: 10 ÷ 7 = 1 with a remainder of 3

Adding 3 days to Wednesday gives Saturday.

Explanation

To arrange the words in alphabetical order as they appear in a dictionary, we compare their letters from left to right. All four words start with the prefix Co, so we must compare their third letters.

In Collaborate, the third letter is l. In Combination, the third letter is m. In Constant, the third letter is n. In Correspondence, the third letter is r.

Arranging these third letters in alphabetical order gives l, m, n, and r. Consequently, Collaborate comes first, followed by Combination, then Constant, and finally Correspondence. This yields the dictionary sequence of i, iv, ii, iii.

Explanation

The code for each letter is determined by direct substitution from the given word TAPERECORDER to the coded sequence !# | @^@?%*+@^:

T -> ! A -> # P -> | E -> @ R -> C -> ? O -> % D -> +

Applying these letter-to-symbol relationships to the word REPORT:

R -> E -> @ P -> | O -> % R -> T -> !

Thus, the code for REPORT is ^@ | %^!.

Explanation

In each row, the second number is the square of the first number, and the third number is the square of the number obtained by reversing the digits of the first number.

For the first row: 13² = 169 Reversing the digits of 13 gives 31, and 31² = 961.

For the third row: 12² = 144 Reversing the digits of 12 gives 21, and 21² = 441.

Following the same logic for the second row, the missing value is the square of the first number, which is 15² = 225, with the third number being the square of the reversed digits, 51² = 2601.

Explanation

Substitute the given symbols with their corresponding mathematical operators: | is ÷ @ is × % is - is +

Applying these to the expression: 153 ÷ 17 × 6 - 9 + 18

According to the BODMAS rule, perform the operations in the order of division, multiplication, addition, and subtraction:

First, perform division: 153 ÷ 17 = 9

Next, perform multiplication: 9 × 6 = 54

Finally, perform addition and subtraction: 54 - 9 + 18 = 63

Explanation

The series follows a pattern where the number of occurrences of the letter e increases by one in each successive group of letters.

By dividing the complete series, we get: def / deef / deeef

To achieve this pattern, the letters sequentially placed in the gaps are e, e, f, and f, which forms eeff.

Explanation

Let the starting point of the man be at the origin (0, 0) on a standard coordinate system where North is the positive y-axis, South is the negative y-axis, East is the positive x-axis, and West is the negative x-axis.

The man first travels 25 km West, which shifts his position to (-25, 0).

From this position, turning 90° to his left means he is now facing South. Traveling 4 km in this direction moves him to the coordinate (-25, -4).

Finally, turning left from facing South means he is now facing East. Traveling 25 km in this direction shifts his x-coordinate by +25, bringing him to (0, -4).

Comparing his final coordinate of (0, -4) to his starting coordinate of (0, 0) shows that he is located directly South of his starting point.

Explanation

The word HUNT is represented by the codes 13, 11, 30, 41 in Matrix-I by identifying the row number first, followed by the column number.

The first letter H is found at row 1 and column 3, giving the code 13. The second letter U is found at row 1 and column 1, giving the code 11. The third letter N is found at row 3 and column 0, giving the code 30. The fourth letter T is found at row 4 and column 1, giving the code 41.

Explanation

The expression my wife refers to the man's wife. The daughter of my wife is the man's daughter. Consequently, the daughter of the daughter of my wife is the daughter of his own daughter, which makes her his granddaughter. Since the man is the father of the girl's mother, he is her maternal grandfather.
