Explanation

The relationship between the letter pairs is determined by two different rules applied to the first and second letters.

For the first letter, the positional value increases by 2: R (18) + 2 = T (20)

For the second letter, it is replaced by its opposite letter in the alphabet, where the sum of their positional ranks is 27: V (22) is opposite to E (5), since 22 + 5 = 27

Applying the same logic to EL: The first letter E (5) increases by 2 to give G (7). The second letter L (12) is replaced by its opposite letter O (15), since 12 + 15 = 27.

This yields the pair GO.

Explanation

The series is formed by concatenating successive alphabetical groups of increasing lengths: Group 1: A Group 2: AB Group 3: ABC Group 4: ABCD Group 5: ABCDE

Concatenating these groups yields the continuous sequence: AABABCABCDABCDE

Comparing this sequence with the given template: AA_AB_ABC_A_C_E

The letters that fill the blank spaces in order are B, C, D, B, and D. This corresponds to the sequence BCDBD.

Explanation

C is the mother of Y. Since N, Y, and B are siblings (N is Y's brother and Y is B's sister), C is also the mother of B. B is the wife of Z, which means Z is the husband of C's daughter. Therefore, Z is the son-in-law of C.

Explanation

Let the first number in the set be x. The mathematical relationship between the three numbers in each set is represented by the pattern where the second number is x² - 1 and the third number is (x + 1)².

For the first set (8, 63, 81): 8² - 1 = 64 - 1 = 63 (8 + 1)² = 9² = 81

For the second set (11, 120, 144): 11² - 1 = 121 - 1 = 120 (11 + 1)² = 12² = 144

Applying this same pattern to the set in option A (9, 80, 100): 9² - 1 = 81 - 1 = 80 (9 + 1)² = 10² = 100

Explanation

The series follows an alternating addition pattern where the differences between consecutive terms alternate between +39 and +78.

Calculating the differences between successive terms: 87 - 48 = 39 165 - 87 = 78 204 - 165 = 39 282 - 204 = 78 321 - 282 = 39

Following this established sequence, the next difference must be +78. Adding this to the last term: 321 + 78 = 399

Explanation

The general logic for the correct pairs is that the number on the right is the square of the number on the left, which can be represented by the relation y = x².

For the pair 104 - 10886, the square of the first number is 104² = 10816. Since the second number is given as 10886, this pair does not satisfy the squaring relation, making it the odd one out.

Explanation

In the pair Carpenter - Furniture, the creator (Carpenter) is placed first and the product (Furniture) is placed second. This is the reverse of the sequence followed in the other pairs, where the product is listed before its creator, making this pair the odd one out.

Explanation

Statement II states that No white is black. In syllogisms, a negative proposition of the form No A is B is mutually exclusive and symmetric, which means it can be directly converted to No B is A. Therefore, the statement No white is black directly implies that No black is white. This makes Conclusion I logically valid.

Explanation

The given equation with the division operator is: 13 + 9 ÷ 78 × 27 - 16 = 3

By interchanging the numbers 3 and 78, the equation becomes: 13 + 9 ÷ 3 × 27 - 16 = 78

Applying the BODMAS rule:

First, perform the division: 9 ÷ 3 = 3 The equation becomes: 13 + 3 × 27 - 16 = 78

Next, perform the multiplication: 3 × 27 = 81 The equation becomes: 13 + 81 - 16 = 78

Finally, solve the addition and subtraction: 94 - 16 = 78 78 = 78

Since LHS equals RHS, the equation is balanced.

Explanation

The relationship between the numbers in each set follows the mathematical pattern:

A³ - B² = C

where A, B, and C represent the first, second, and third numbers in the set, respectively.

Applying this pattern to the given sets:

For the set (8, 9, 431): 8³ - 9² = 512 - 81 = 431

For the set (11, 8, 1267): 11³ - 8² = 1331 - 64 = 1267

Applying the same pattern to the set in option C, (7, 5, 318): 7³ - 5² = 343 - 25 = 318

Explanation

The letter group SPL is the odd one out because the alphabetical difference between its consecutive letters is not uniform. The numerical positions of S, P, and L in the alphabetical series are 19, 16, and 12, respectively. The difference between S and P is 3 (19 - 16 = 3), while the difference between P and L is 4 (16 - 12 = 4). All other letter groups follow a constant difference of 3 between consecutive letters.

Explanation

The relation between the pairs of numbers follows the pattern where the second number is obtained by subtracting 2 from the square of the first number.

Second number = (First number)² - 2

Applying this rule to the given pairs:

19² - 2 = 361 - 2 = 359

17² - 2 = 289 - 2 = 287

21² - 2 = 441 - 2 = 439

Explanation

From the given information, we can map the family relationships step by step.

Q is the sister of R, and R is the brother of S, which means Q, R, and S are siblings.

P is the father of Q, which makes P the father of all three siblings: Q, R, and S.

Since S is the son of T, and we already know P is the father of S, T must be the mother of S.

As P is the father and T is the mother of the same children, T is married to P. Therefore, T is the wife of P.

Explanation

The coding follows a two-step pattern of reversing the word and then subtracting 2 from the letters at the odd positions while leaving the letters at the even positions unchanged.

Step 1: Reverse the letters of the word WEIGHS. WEIGHS becomes S H G I E W.

Step 2: Subtract 2 from the letters at the odd positions (1st, 3rd, and 5th) and keep the even-positioned letters (2nd, 4th, and 6th) unchanged. 1st letter: S (19) - 2 = Q (17) 2nd letter: H remains H 3rd letter: G (7) - 2 = E (5) 4th letter: I remains I 5th letter: E (5) - 2 = C (3) 6th letter: W remains W This yields the code QHEICW.

Applying the same logic to ABUSES:

Step 1: Reverse the word ABUSES. ABUSES becomes S E S U B A.

Step 2: Apply the same pattern to S E S U B A. 1st letter: S (19) - 2 = Q (17) 2nd letter: E remains E 3rd letter: S (19) - 2 = Q (17) 4th letter: U remains U 5th letter: B (2) - 2 = Z (26) 6th letter: A remains A

Combining these letters gives QEQUZA.

Explanation

Telephone is a telecommunication device designed for transmitting and receiving sound, specifically human voice, over distances, whereas the other three items are musical instruments.

Explanation

The numbers in the given sets follow the mathematical relationship b = a × (a - c), where the set of numbers is represented as (a, b, c).

Applying this formula to the given sets: For (14, 112, 6): 14 × (14 - 6) = 14 × 8 = 112

For (17, 204, 5): 17 × (17 - 5) = 17 × 12 = 204

Applying the same logic to the set (21, 189, 12): 21 × (21 - 12) = 21 × 9 = 189

Explanation

Correct Answer: B

The given series follows an alternating multiplication pattern of × 2 and × 3.

59 × 2 = 118 118 × 3 = 354 354 × 2 = 708 708 × 3 = 2124

Following this pattern, the next number in the series is obtained by multiplying the previous term by 2:

2124 × 2 = 4248

Explanation

A mouse is a peripheral device used to control and navigate the functions of a computer. Similarly, a remote is a device used to control and navigate the functions of a television.

Explanation

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

All five words begin with the letters Mac.

Comparing the fourth letter of each word, Macabre (2) and Macaroni (4) have the letter a, while Machine (1), Machinery (3), and Machete (5) have the letter h. Since a comes before h, Macabre and Macaroni will appear first. Comparing the fifth letter of these two, b in Macabre comes before r in Macaroni, giving the initial order 2, 4.

Next, comparing the three remaining words starting with Mach, the fifth letter in Machete (5) is e, while in Machine (1) and Machinery (3) it is i. Since e comes before i, Machete is placed next, updating the sequence to 2, 4, 5.

Finally, comparing Machine (1) and Machinery (3), Machine is a complete subset of Machinery, meaning the shorter word Machine appears first. This gives the final dictionary order as 2, 4, 5, 1, 3.

Explanation

The letters in the first group are shifted forward by 3 positions in alphabetical order to obtain the corresponding letters of the second group.

A + 3 = D (1 + 3 = 4) J + 3 = M (10 + 3 = 13) N + 3 = Q (14 + 3 = 17)

Applying the same logic to PTW:

P + 3 = S (16 + 3 = 19) T + 3 = W (20 + 3 = 23) W + 3 = Z (23 + 3 = 26)

This yields the letter group SWZ.

Explanation

The relationship in the given sets is based on the pattern where the second number is twice the first number, and the third number is four times the second number. This can be represented as (a, 2a, 8a).

For the first given set: 32 × 2 = 64 64 × 4 = 256

For the second given set: 18 × 2 = 36 36 × 4 = 144

Applying this same logic to the correct option: 37 × 2 = 74 74 × 4 = 296

Explanation

The series follows a specific addition pattern for each letter position:

For the first letter of each term, add 6 to the alphabetical position: A (1) + 6 = G (7) G (7) + 6 = M (13) M (13) + 6 = S (19) S (19) + 6 = Y (25)

For the second letter of each term, add 9 to the alphabetical position: N (14) + 9 = W (23) W (23) + 9 = F (32, which is 6 in the 26-letter cycle) F (6) + 9 = O (15) O (15) + 9 = X (24)

For the third letter of each term, the letters alternate: M -> Z -> M -> Z -> M

Combining these letters gives the next term in the series as YXM.

Explanation

By decoding the letter-based operators, we find the standard mathematical symbols they represent: B represents ÷ (division) C represents + (addition) D represents - (subtraction) A represents × (multiplication)

Substituting these operators into the given expression: 94 ÷ 47 + 63 - 14 × 5 + ? = -2

Applying the BODMAS rule: First, perform the division: 94 ÷ 47 = 2

Next, perform the multiplication: 14 × 5 = 70

Substitute these values back into the expression: 2 + 63 - 70 + ? = -2

Now perform addition and subtraction from left to right: 65 - 70 + ? = -2 -5 + ? = -2

Solving for ?: ? = -2 + 5 ? = 3

Explanation

The coding pattern splits the eight-letter word into two halves of four letters each.

For the first four letters, the reverse alphabetical positional values are used, which can be calculated as 27 minus the standard positional value of the letter.

For the last four letters, the standard alphabetical positional values (A = 1, B = 2, ..., Z = 26) are used directly.

Applying this rule to the word LIKEWISE:

The first half is LIKE: L has a standard position of 12, so its reverse position is 27 - 12 = 15. I has a standard position of 9, so its reverse position is 27 - 9 = 18. K has a standard position of 11, so its reverse position is 27 - 11 = 16. E has a standard position of 5, so its reverse position is 27 - 5 = 22.

The second half is WISE: W has a standard position of 23. I has a standard position of 9. S has a standard position of 19. E has a standard position of 5.

Combining these values in sequence yields 15181622239195.

Explanation

The letter cluster GHI consists of consecutive letters arranged in forward alphabetical order, where each subsequent letter increases by 1 position: G (7) → H (8) → I (9). The other three clusters are formed by consecutive letters arranged in reverse alphabetical order, decreasing by 1 position each time. This makes GHI the odd one out.

Explanation

The relationship between the numbers in each pair follows the formula:

y = (x ÷ 3)²

In the first pair, substituting x = 33 gives: (33 ÷ 3)² = 11² = 121

In the second pair, substituting x = 27 gives: (27 ÷ 3)² = 9² = 81

Applying this same relationship to the fifth number, where x = 45, we get: (45 ÷ 3)² = 15² = 225

Explanation

A tadpole is the larval stage in the life cycle of a frog. Applying the same relationship, a caterpillar is the larval stage in the life cycle of a butterfly. Both represent the immature, active developmental stage of these organisms before they undergo metamorphosis to reach their adult form.

Explanation

No mobile is an electronic item and all electronic items are costly. From these statements, the relationship between the class of costly items and the class of mobiles is not definitely established.

There are only two logical possibilities regarding the intersection of the set of costly items and the set of mobiles: either they have no elements in common, or they have at least one element in common.

Conclusion I states that no costly item is a mobile, which represents the case of zero intersection. Conclusion II states that some costly items are mobiles, which represents the case of a non-empty intersection.

Because both conclusions share the same subject and predicate, are individually undetermined by the premises, and form a complementary pair of No and Some, one of the two statements must always be true. Therefore, either conclusion I or II follows.

Explanation

The relationship between the numbers in each set follows the logic where the difference of the squares of the first two numbers equals the third number.

Formula: a² - b² = c

Using the first set (8, 5, 39): 8² - 5² = 64 - 25 = 39

Using the second set (14, 11, 75): 14² - 11² = 196 - 121 = 75

Applying this same logic to the numbers in the set (7, 4, 33): 7² - 4² = 49 - 16 = 33

Explanation

Aman is the brother of Baman and Chaman, which means that Aman, Baman, and Chaman are siblings. Since Baman is the mother of Emily, Baman is female. Because Baman is female and a sibling of Chaman, Baman is definitely the sister of Chaman.

Explanation

The coding scheme follows an alternating pattern of subtracting 1 and adding 1 to the positional values of the letters of the word.

For the word BANGLE: B minus 1 is A A plus 1 is B N minus 1 is M G plus 1 is H L minus 1 is K E plus 1 is F

Applying this alternating pattern of -1, +1, -1, +1, -1, +1 yields the coded word ABMHKF.

Explanation

The complete letter series consists of 18 letters divided into three distinct blocks of 6 letters each: W X Y W W X, Y X W Y W X, and X W Y X Y Y.

Inside each 6-letter block, the first 3 letters form a permutation of the set {W, X, Y}. In Block 1, the first half is W X Y. In Block 2, the first half is Y X W. In Block 3, the first half is X W Y.

The second half of each block is structured to progressively shift the frequency of each letter across the blocks: Block 1 (W X Y W W X) contains 3 Ws, 2 Xs, and 1 Y. Block 2 (Y X W Y W X) contains 2 Ws, 2 Xs, and 2 Ys. Block 3 (X W Y X Y Y) contains 1 W, 2 Xs, and 3 Ys.

Placing the letters from YXXYwXY (where the lowercase w represents W) sequentially into the seven gaps of the series W X _ W W _ Y _ W _ W X X _ Y _ Y _ yields this complete sequence: W X Y W W X Y X W Y W X X W Y X Y Y.

Explanation

In the group (Car, Truck, Road), the first two words, Car and Truck, represent types of vehicles, whereas the third word, Road, is the pathway on which they travel. This inclusion of a different category makes this group heterogeneous, distinguishing it from the other groups which consist entirely of elements belonging to a single, identical category.

Explanation

To find the fifth word in alphabetical order, we compare the given words letter by letter from left to right. All five words share the same first three letters, which are W-r-a.

Comparing their fourth letters, we have: Wrack (c) Wrangler (n) Wrap (p) Wrasse (s) Wrath (t)

Sorting these fourth letters alphabetically yields c, n, p, s, t. The complete dictionary order of the words is Wrack, Wrangler, Wrap, Wrasse, and Wrath, which positions Wrath as the fifth word.

Explanation

The relationship in the given pair is that of a professional and their primary working tool. A farmer uses a plough to cultivate land. Similarly, a surgeon is a medical professional who uses a scalpel as their primary tool to perform surgical procedures.

Explanation

For expression I, interchanging the signs + and - gives: 45 - 15 × 30 ÷ 10 + 25

Applying the BODMAS rule, first perform the division: 30 ÷ 10 = 3

Next, perform the multiplication: 15 × 3 = 45

Finally, perform addition and subtraction: 45 - 45 + 25 = 25

For expression II, interchanging the signs + and - gives: 6 × 9 - 5 + 8 ÷ 4

Applying the BODMAS rule, first perform the division: 8 ÷ 4 = 2

Next, perform the multiplication: 6 × 9 = 54

Finally, perform addition and subtraction: 54 - 5 + 2 = 51

Explanation

The operation R represents the relationship where the second number is subtracted from the first number, and the resulting difference is divided by 2. This can be expressed as:

x R y = (x - y)/2

Applying this formula to the first two examples:

739 R 635 = (739 - 635)/2 = 104/2 = 52

814 R 122 = (814 - 122)/2 = 692/2 = 346

Applying the same formula to the target numbers:

532 R 220 = (532 - 220)/2 = 312/2 = 156

Explanation

The numbers in the given sets follow the mathematical relationship of a number, its square, and its cube. The pattern for any set (x, y, z) is: y = x² z = x³

In the first given set (12, 144, 1728): 12² = 144 12³ = 1728

In the second given set (6, 36, 216): 6² = 36 6³ = 216

Following this exact rule, the set (10, 100, 1000) satisfies the relationship: 10² = 100 10³ = 1000

Explanation

The given series follows a pattern where each term, starting from the third term, is the sum of the preceding two terms.

3 + 4 = 7 4 + 7 = 11 7 + 11 = 18 11 + 18 = 29

Following this logic, the missing number is the sum of the last two known terms: 18 + 29 = 47

Explanation

The coding pattern uses the formula: (Sum of the alphabetical positions of the letters)² + 1.

For BED: B = 2, E = 5, D = 4 Sum of positions = 2 + 5 + 4 = 11 Code = 11² + 1 = 121 + 1 = 122

For CAB: C = 3, A = 1, B = 2 Sum of positions = 3 + 1 + 2 = 6 Code = 6² + 1 = 36 + 1 = 37

Applying the same logic for ADD: A = 1, D = 4, D = 4 Sum of positions = 1 + 4 + 4 = 9 Code = 9² + 1 = 81 + 1 = 82

Explanation

The logic applied to the pairs is that the difference between the second number and the first number is a constant value of 2481.

4835 - 2354 = 2481 3807 - 1326 = 2481 4826 - 2345 = 2481

For the first pair, the difference is 2491:

5732 - 3241 = 2491

Since this pair does not follow the constant difference rule of 2481, it is the odd one out.

Explanation

The given operation a % b % c rearranges the digits a, b, and c into the pattern bca.

In the first equation, 8 % 3 % 2 rearranged as bca gives 328.

In the second equation, 4 % 2 % 6 rearranged as bca gives 264.

Applying this pattern to the expression 1 % 7 % 3, where a = 1, b = 7, and c = 3, rearranging the digits according to bca yields 731.

Explanation

The pair Karnataka - Bengaluru follows the order of State - Capital, whereas all the other pairs follow the order of Capital - State.

Explanation

Interchanging the signs × and + in both equations:

For Equation I: 7 - 6 × 2 × 1 + 9 Applying BODMAS rule, first perform the multiplication: 6 × 2 × 1 = 12 Then, perform addition and subtraction: 7 - 12 + 9 = 4 Since 4 is not equal to 2, Equation I is not correct.

For Equation II: 16 × 4 - 9 + 1 × 3 Applying BODMAS rule, first perform the multiplication: 16 × 4 = 64 1 × 3 = 3 Now, perform addition and subtraction: 64 - 9 + 3 = 58 Since 58 is not equal to 60, Equation II is also not correct.

Thus, both equations I and II are not correct after the interchange.

Explanation

The series is formed by applying a constant addition pattern to the alphabetical positions of each letter in the terms.

For the first letter of each term, the positions are N (14), T (20), Z (26), and F (6). There is a constant addition of 6 to each position. Following this pattern, the next position is 6 + 6 = 12, which corresponds to the letter L.

For the second letter of each term, the positions are T (20), V (22), X (24), and Z (26). There is a constant addition of 2 to each position. Following this pattern, the next position is 26 + 2 = 28. Since there are 26 letters in the alphabet, 28 corresponds to the second letter, which is B.

For the third letter of each term, the positions are R (18), Z (26), H (8), and P (16). There is a constant addition of 8 to each position. Following this pattern, the next position is 16 + 8 = 24, which corresponds to the letter X.

Combining these letters gives the next term in the series as LBX.

Explanation

The logic followed in the given pair is that the first word represents a broad category, while the second word is a specific example belonging to that category. Black is a specific type of colour.

Applying this logic, furniture represents a broad category of household items, and a table is a specific example of an item that belongs to the furniture category.

Explanation

Statement I states that all truck are car. This logically implies that some truck are car, which validates Conclusion II.

Statement II states that some car are bike. By the rule of conversion, the proposition some A are B logically implies some B are A. Therefore, some bike are car, which validates Conclusion III.

Since both Conclusion II and Conclusion III logically follow from the given statements, the correct option is D.

Explanation

The series follows an alternating addition pattern where the consecutive differences between the terms are alternately 14 and 28.

82 - 68 = 14 110 - 82 = 28 124 - 110 = 14 152 - 124 = 28

Following this alternating pattern of adding 14 and 28, the next number is obtained by adding 14 to the previous term:

152 + 14 = 166

To verify, adding 28 to 166 gives the next term in the series:

166 + 28 = 194

Explanation

The relationship between the numbers in the given sets is that the sum of the first and the third numbers equals the second number:

First number + Third number = Second number

For the first set (18, 66, 48): 18 + 48 = 66

For the second set (52, 144, 92): 52 + 92 = 144

Applying this logic to the correct set: 24 + 32 = 56

Explanation

The numbers in each set (a, b, c) follow the relationship where the third number is equal to the product of the second number and the fourth power of the first number.

c = b × a⁴

Applying this formula to the given sets: For (3, 2, 162): 2 × 3⁴ = 2 × 81 = 162

For (6, 3, 3888): 3 × 6⁴ = 3 × 1296 = 3888

Applying the same formula to the set in Option D (7, 2, 4802): 2 × 7⁴ = 2 × 2401 = 4802
