Explanation

Correct Answer: B

Using the calendar odd days method, the number of odd days from 24 July 1999 to 24 July 2003 can be calculated over the four-year interval. Among these years, 2000 is a leap year which contributes 2 odd days, while 2001, 2002, and 2003 are ordinary years, each contributing 1 odd day.

Total odd days from 24 July 1999 to 24 July 2003 = 2 + 1 + 1 + 1 = 5 odd days.

The target date of 28 July 2003 is 4 days after 24 July 2003.

Total cumulative odd days = 5 + 4 = 9 odd days.

Dividing 9 by 7 yields a remainder of 2 odd days. Adding 2 days to Saturday results in Monday.

Explanation

To find the relationship between Q and V, decode the expression from right to left starting from V:

U @ V means U is the father of V.

T | U means T is the wife of U. Since U is the father of V, T must be the mother of V.

L + T means L is the sister of T.

Q @ L means Q is the father of L. Since L and T are sisters, Q is also the father of T.

Since T is the mother of V, and Q is the father of T, Q is the mother's father of V.

Explanation

The relationship between the letter groups is determined by shifting the alphabetical positions of the letters alternately by +1 and -1.

By analyzing the first pair, JHDC to KGEB: J is shifted by +1 to K H is shifted by -1 to G D is shifted by +1 to E C is shifted by -1 to B

The same pattern applies to the second pair, QOKJ to RNLI: Q is shifted by +1 to R O is shifted by -1 to N K is shifted by +1 to L J is shifted by -1 to I

Applying this established pattern of +1, -1, +1, -1 to USON: U is shifted by +1 to V S is shifted by -1 to R O is shifted by +1 to P N is shifted by -1 to M

This gives the final letter group VRPM.

Explanation

From the given statements, we can establish the relationship between the categories using set containment.

First, because all ladders are chairs and all chairs are tables, the set of ladders is entirely contained within the set of chairs, which itself is entirely contained within the set of tables. This implies that all ladders are tables. Consequently, there is an overlap between tables and ladders, meaning some tables are indeed ladders. Thus, conclusion I is correct.

Second, we are given that no table is a stair, meaning the set of tables and the set of stairs have no elements in common. Since the set of chairs is entirely contained within the set of tables, chairs also cannot have any overlap with stairs. Therefore, no chair is a stair. Thus, conclusion II is correct.

Lastly, because ladders are also entirely contained within tables, they cannot overlap with stairs either, which makes conclusion III incorrect.

Explanation

By comparing the words BORN and NORM, the common letters are O, R, and N. The corresponding common digits in their codes 8234 and 6328 are 8, 2, and 3. This means the letters O, R, and N are represented by the digits 8, 2, and 3 in some order.

The only remaining letter in NORM is M, and the only remaining digit in its code 6328 is 6. Therefore, the letter M is coded as 6.

Explanation

The terms in the series follow the recursive relation where each term is obtained by multiplying the previous term by 2 and then subtracting 5.

Tₙ = 2 × Tₙ₋₁ - 5

Applying this formula to each term of the series: Second term = 2 × 33 - 5 = 66 - 5 = 61 Third term = 2 × 61 - 5 = 122 - 5 = 117 Fourth term = 2 × 117 - 5 = 234 - 5 = 229 Fifth term = 2 × 229 - 5 = 458 - 5 = 453

Explanation

The relation between the numbers in each pair follows the linear formula y = 3x + 1, where x is the first number and y is the second number.

For the first pair: 14 × 3 + 1 = 42 + 1 = 43

For the second pair: 17 × 3 + 1 = 51 + 1 = 52

Applying the same formula to the number 19: 19 × 3 + 1 = 57 + 1 = 58

Explanation

By interchanging the mathematical operators as specified: "×" is replaced by "÷" "-" is replaced by "+" "+" is replaced by "-"

The original expression 204 × 6 - 6 + 4 + 7 is rewritten as: 204 ÷ 6 + 6 - 4 - 7

Applying the order of operations (BODMAS rule):

First, perform the division: 204 ÷ 6 = 34

Next, substitute this value back into the expression: 34 + 6 - 4 - 7

Finally, perform the addition and subtraction from left to right: 34 + 6 = 40 40 - 4 = 36 36 - 7 = 29

Explanation

The logic followed in the given sets is: First number + Second number = Third number First number = 3 × Second number Third number = 4 × Second number

Applying this to the first set (12, 4, 16): 12 + 4 = 16 12 = 3 × 4 16 = 4 × 4

Applying this to the second set (27, 9, 36): 27 + 9 = 36 27 = 3 × 9 36 = 4 × 9

Similarly, for the set (39, 13, 52): 39 + 13 = 52 39 = 3 × 13 52 = 4 × 13

Explanation

A bulb is the specialized underground storage structure and organ of vegetative propagation from which a tulip grows. This represents a specific biological relationship where the first term is the plant organ/propagule from which the second term (the plant) develops and flourishes.

Explanation

By substituting the correct mathematical operators where A stands for ÷, B stands for ×, C stands for +, and D stands for -, the given equation is:

62 × 2 - 190 ÷ 5 + 7

Applying the BODMAS rule, first perform the division operation: 190 ÷ 5 = 38

Next, perform the multiplication operation: 62 × 2 = 124

Now, substitute these values back into the expression and perform the addition and subtraction: 124 - 38 + 7 = 93

Explanation

The differences between consecutive terms in the series form a sequence of multiples of 11:

77 - 66 = 11 99 - 77 = 22 132 - 99 = 33 176 - 132 = 44

Following this pattern of increasing the difference by 11 at each step, the next difference must be 55.

Adding 55 to the last term: 176 + 55 = 231

Explanation

The standard pattern among the letter-clusters is that they are composed of two consecutive pairs of opposite letters, where the sum of the alphabetical positions of the first two letters is 27, and the sum of the last two letters is also 27.

In the cluster PLRI, the alphabetical positions of the letters are P = 16, L = 12, R = 18, and I = 9. The sum of the positions of the first two letters is 16 + 12 = 28, meaning P and L are not opposite letters, as their sum is not 27. Thus, PLRI does not follow the opposite-letter pair pattern, making it the different letter-cluster.

Explanation

The year 2020 is a leap year, meaning it contains 366 days and has 2 odd days (366 divided by 7 leaves a remainder of 2). Adding 2 days to Wednesday (1 January 2020) gives Friday (1 January 2021).

Explanation

The given sequence follows a geometric progression where each successive term is obtained by multiplying the preceding term by a constant factor of 5.

The terms of the series are calculated as follows: First term = 4 Second term = 4 × 5 = 20 Third term = 20 × 5 = 100 Fourth term = 100 × 5 = 500 Fifth term = 500 × 5 = 2500

Following this pattern, the next term in the series is: 2500 × 5 = 12500

Explanation

The given series follows a pattern where the difference between consecutive terms increases by 10 at each step.

141 - 131 = 10 161 - 141 = 20 191 - 161 = 30 231 - 191 = 40

Following this arithmetic pattern, the next difference in the sequence must be 50.

Adding 50 to the last term: 231 + 50 = 281

Explanation

In the first phrase 'make someone happy', the code is 'Ab Te Dp'. In the second phrase 'someone robbed him', the code is 'Te Ko Vi'.

Comparing the two phrases, the word 'someone' is the only common word. Similarly, comparing the two sets of codes, 'Te' is the only common code. Therefore, 'someone' is written as 'Te'.

Explanation

The relationship between the letter groups is established by shifting each letter backward by 6 positions in the English alphabetical order.

By checking the first pair, MAZQ to GUTK: M (13) - 6 = G (7) A (1/27) - 6 = U (21) Z (26) - 6 = T (20) Q (17) - 6 = K (11)

Similarly, for CPNR to WJHL: C (3/29) - 6 = W (23) P (16) - 6 = J (10) N (14) - 6 = H (8) R (18) - 6 = L (12)

Applying the same subtraction logic to KOEV: K (11) - 6 = E (5) O (15) - 6 = I (9) E (5/31) - 6 = Y (25) V (22) - 6 = P (16)

This yields the letter group EIYP.

Explanation

The pattern followed by the given pairs is that each letter in the first group is paired with its opposite/reverse letter in the alphabetical series (where the sum of their numerical positions is 27).

In the first pair FJM : UQN: F (6) + U (21) = 27 J (10) + Q (17) = 27 M (13) + N (14) = 27

In the second pair DPQ : WKJ: D (4) + W (23) = 27 P (16) + K (11) = 27 Q (17) + J (10) = 27

Applying this same rule to the pair OVC : LEX: O (15) + L (12) = 27 V (22) + E (5) = 27 C (3) + X (24) = 27

Explanation

Correct Answer: B

By assigning standard mathematical operations to the letters, where A represents division (÷), B represents multiplication (×), C represents addition (+), and D represents subtraction (-), the equation is rewritten as:

128 ÷ 4 + 16 × 7 - 5

Applying the BODMAS rule:

First, perform the division: 128 ÷ 4 = 32

Next, perform the multiplication: 16 × 7 = 112

Finally, perform the addition and subtraction: 32 + 112 - 5 = 144 - 5 = 139

Explanation

The difference between the alphabetical positions of the letters in LNP is +2 and +2, where L is 12, N is 14, and P is 16. This differs from the +2 and +3 positional difference pattern followed by the other letter clusters.

Explanation

The logic governing the relationship between the numbers is: y = 2x + 4

where x is the first number and y is the related second number.

Applying this relation to the first pair: 2 × 38 + 4 = 76 + 4 = 80

Applying the same relation to the second pair: 2 × 42 + 4 = 84 + 4 = 88

Following this logic, the number related to 29 is calculated as: 2 × 29 + 4 = 58 + 4 = 62

Explanation

To find the number of letters whose position changes when the word TROUBLEMAKING is arranged alphabetically from left to right, we compare the original letter sequence with the sorted alphabetical sequence.

The original word consists of 13 letters in the following order: T, R, O, U, B, L, E, M, A, K, I, N, G.

Arranging these 13 letters in alphabetical order from left to right gives: A, B, E, G, I, K, L, M, N, O, R, T, U.

Comparing the positions in both sequences shows: Position 1: T changes to A Position 2: R changes to B Position 3: O changes to E Position 4: U changes to G Position 5: B changes to I Position 6: L changes to K Position 7: E changes to L Position 8: M remains M (unchanged) Position 9: A changes to N Position 10: K changes to O Position 11: I changes to R Position 12: N changes to T Position 13: G changes to U

Out of the 13 letters, only M at the eighth position remains in its original place. Therefore, the positions of exactly twelve letters will change.

Explanation

Let T, G, M, and P represent tables, gates, mats, and plates respectively.

According to the statements, all mats are tables (M is a subset of T), some tables are gates (there is an overlap between T and G), and all plates are gates (P is a subset of G).

For Conclusion I (All gates are mats), there is no definite relationship established between gates and mats. Mats are a subset of tables, and gates overlap with tables, meaning they do not necessarily overlap with mats. Therefore, Conclusion I does not logically follow.

For Conclusion II (All tables are plates), plates are a subset of gates, and tables only partially overlap with gates. There is no requirement for all tables to be plates. Therefore, Conclusion II does not logically follow.

Explanation

After interchanging the mathematical signs where plus and division signs are interchanged, and minus and multiplication signs are interchanged, the expression is rewritten.

Replacing the symbols accordingly, the expression becomes: 28 + 90 ÷ 6 × 5 - 17

According to the BODMAS rule, division is performed first, followed by multiplication, and then addition and subtraction:

First, perform the division: 90 ÷ 6 = 15

The expression becomes: 28 + 15 × 5 - 17

Next, perform the multiplication: 15 × 5 = 75

The expression becomes: 28 + 75 - 17

Finally, perform the addition and subtraction: 103 - 17 = 86

Explanation

The given series is an arithmetic progression where each subsequent term is obtained by adding a constant difference to the preceding term.

To find the common difference, subtract adjacent known terms: 67 - 55 = 12 55 - 43 = 12

Since the common difference is 12, the missing second term is calculated by adding 12 to the first term: 19 + 12 = 31

To verify, adding 12 to 31 yields the third term: 31 + 12 = 43

Explanation

To find the day of the week on 19 October 2020 starting from 2 August 2016 (Tuesday), we calculate the total number of odd days between the two dates.

First, calculate the odd days for the years from 2 August 2016 to 2 August 2020: From 2 August 2016 to 2 August 2017 is 1 ordinary year (365 days), which gives 1 odd day. From 2 August 2017 to 2 August 2018 is 1 ordinary year, giving 1 odd day. From 2 August 2018 to 2 August 2019 is 1 ordinary year, giving 1 odd day. From 2 August 2019 to 2 August 2020 is 1 leap year (366 days, since February 2020 has 29 days), giving 2 odd days. Total odd days for these four years = 1 + 1 + 1 + 2 = 5 odd days.

Next, calculate the odd days from 2 August 2020 to 19 October 2020: Remaining days in August = 31 - 2 = 29 days, which is 1 odd day (29 = 4 × 7 + 1). Days in September = 30 days, which is 2 odd days (30 = 4 × 7 + 2). Days in October = 19 days, which is 5 odd days (19 = 2 × 7 + 5). Total odd days for this period = 1 + 2 + 5 = 8 odd days, which simplifies to 1 odd day (8 - 7 = 1).

Adding the two parts together gives a total of 5 + 1 = 6 odd days.

Advancing Tuesday by 6 days gives Monday.

Explanation

The series is formed by analyzing the alphabetical positions of each letter from right to left: HEB → QMI → ZUP → ? → RKD.

For the first letter of each term, the position increases by 9 from right to left: H (8) + 9 = Q (17) Q (17) + 9 = Z (26) Z (26) + 9 = I (9, after wrapping around the 26-letter alphabet) I (9) + 9 = R (18)

For the second letter of each term, the position increases by 8 from right to left: E (5) + 8 = M (13) M (13) + 8 = U (21) U (21) + 8 = C (3, after wrapping around) C (3) + 8 = K (11)

For the third letter of each term, the position increases by 7 from right to left: B (2) + 7 = I (9) I (9) + 7 = P (16) P (16) + 7 = W (23) W (23) + 7 = D (4, after wrapping around)

Combining these letters gives the missing term ICW.

Explanation

Each letter-cluster in the series consists of three consecutive letters of the alphabet.

Looking at the first letter of each cluster: E is the 5th letter of the alphabet. K is the 11th letter of the alphabet, which is 5 + 6. Q is the 17th letter of the alphabet, which is 11 + 6.

Following this pattern of adding 6 to the alphabetical position, the first letter of the next cluster is 17 + 6 = 23, which corresponds to the letter W.

Since the letters in each cluster are consecutive, the cluster starting with W is WXY.

Explanation

The numbers in each set (A, B, C) follow a specific pattern of differences: A - B = 28 A - C = 11 C - B = 17

Applying this to the given sets: For (81, 53, 70): 81 - 53 = 28 81 - 70 = 11 70 - 53 = 17

For (94, 66, 83): 94 - 66 = 28 94 - 83 = 11 83 - 66 = 17

Applying the same pattern to the set (99, 71, 88): 99 - 71 = 28 99 - 88 = 11 88 - 71 = 17

Explanation

By comparing the words YOUR and CROY, the common letters are O, R, and Y. The common digits between their respective codes 5627 and 2769 are 2, 6, and 7. This indicates that the letter group {O, R, Y} corresponds to the digit group {2, 6, 7} in some order. The letter C is present only in CROY, and the digit 9 is present only in its corresponding code 2769. Therefore, the code for the letter C is 9.

Explanation

Applying the correct interchange of signs where '+' and '-' are interchanged, and '×' and '÷' are interchanged, the expression is:

10 - 12 ÷ 7 + 84 × 21 = ?

Interchanging the signs as specified: '-' becomes '+' '÷' becomes '×' '+' becomes '-' '×' becomes '÷'

The new equation is: 10 + 12 × 7 - 84 ÷ 21 = ?

Following the BODMAS rule:

First, perform the division: 84 ÷ 21 = 4

Next, perform the multiplication: 12 × 7 = 84

Now, substitute these values back into the equation: 10 + 84 - 4

Finally, perform the addition and subtraction: 94 - 4 = 90

Explanation

Each term in the series is determined by subtracting 4 from the alphabetical positions of the corresponding letters of the preceding term. Representing the letters by their numerical positions where A = 1, B = 2, ..., Z = 26:

For the first letter of each term: D (4) - 4 = Z (26) Z (26) - 4 = V (22) V (22) - 4 = R (18) R (18) - 4 = N (14)

For the second letter of each term: L (12) - 4 = H (8) H (8) - 4 = D (4) D (4) - 4 = Z (26) Z (26) - 4 = V (22)

For the third letter of each term: T (20) - 4 = P (16) P (16) - 4 = L (12) L (12) - 4 = H (8) H (8) - 4 = D (4)

Subtracting 4 from each letter of the third term VDL yields the fourth term RZH.

Explanation

By decoding the symbols to standard mathematical operators, we have: A represents ÷ B represents × C represents + D represents -

Substituting these operators into the expression in option B: 32 B 5 D 10 A 2 C 62 gives: 32 × 5 - 10 ÷ 2 + 62

Following the BODMAS rule of operations, division is performed first: 10 ÷ 2 = 5 This simplifies the expression to: 32 × 5 - 5 + 62

Next, multiplication is performed: 32 × 5 = 160 This simplifies the expression to: 160 - 5 + 62

Finally, addition and subtraction are solved from left to right: 160 - 5 = 155 155 + 62 = 217

Explanation

The relationship between the numbers in each set (A, B, C) follows the pattern where the difference between the second and first number is 24, and the difference between the third and second number is 14.

B - A = 24 C - B = 14

For the first given set (59, 83, 97): 83 - 59 = 24 97 - 83 = 14

For the second given set (63, 87, 101): 87 - 63 = 24 101 - 87 = 14

Applying this same pattern to the set (71, 95, 109): 95 - 71 = 24 109 - 95 = 14

Explanation

The letter groups follow a pattern where each letter is shifted forward by 3 positions in the English alphabetical order.

In the first pair, F is shifted by 3 to I, H is shifted by 3 to K, G is shifted by 3 to J, and E is shifted by 3 to H.

In the second pair, H is shifted by 3 to K, J is shifted by 3 to M, I is shifted by 3 to L, and G is shifted by 3 to J.

Applying this same logic to RTSQ, R plus 3 is U, T plus 3 is W, S plus 3 is V, and Q plus 3 is T, which yields the letters UWVT.

Explanation

To evaluate Conclusion I, we combine the first two statements: All watches are dials and All dials are phones. By transitive property, this directly implies that All watches are phones. Since all watches are phones, the conclusion No watch is a phone is logically incorrect and does not follow.

To evaluate Conclusion II, we look at the statements All dials are phones and Some phones are mobiles. The set of dials is entirely contained within the set of phones, and the set of mobiles overlaps with some part of the set of phones. However, this overlapping region of phones and mobiles does not necessarily intersect with the dials. Therefore, we cannot assert with certainty that Some dials are mobiles.

Since neither conclusion logically follows from the given statements, none of the conclusions follow.

Explanation

The relationship between the terms is established by shifting each letter forward by 5 positions in alphabetical order and adding 11 to the numerical value.

In the first pair, CZ22 and HE33: The letter C (position 3) plus 5 gives H (position 8). The letter Z (position 26) plus 5 wraps around the alphabet to give E (position 5). The number 22 plus 11 gives 33.

In the second pair, QN47 and VS58: The letter Q (position 17) plus 5 gives V (position 22). The letter N (position 14) plus 5 gives S (position 19). The number 47 plus 11 gives 58.

Applying this same logic to WT7: The letter W (position 23) plus 5 wraps around the alphabet to give B (position 2). The letter T (position 20) plus 5 gives Y (position 25). The number 7 plus 11 gives 18.

Combining these components results in BY18.

Explanation

The series follows an alternating pattern of mathematical operations.

First, the number is divided by 2: 800 ÷ 2 = 400

Next, 80 is added to the result: 400 + 80 = 480

Then, the number is divided by 2: 480 ÷ 2 = 240

Next, 80 is added to the result: 240 + 80 = 320

Following this alternating pattern, the next operation is to divide by 2: 320 ÷ 2 = 160

Explanation

The series can be divided into four groups of four letters each: Group 1: J I G P Group 2: K G G U Group 3: L E G Z Group 4: M C G E

By analyzing the corresponding positions of letters in each group, a clear pattern emerges:

The first letter of each group increases by one position in alphabetical order: J → K → L → M.

The second letter of each group decreases by two positions in alphabetical order: I → G → E → C.

The third letter of each group remains constant: G → G → G → G.

The fourth letter of each group increases by five positions in alphabetical order: P → U → Z → E (where Z + 5 cycles back to E).

Placing the letters P, G, L, and C sequentially into the blanks perfectly completes this pattern.

Explanation

By decoding the expression J + K + L × O - P from right to left:

O - P means O is the brother of P.

L × O means L is the father of O. Since O is the brother of P, L is the father of P.

K + L means K is the sister of L.

Since K is the sister of L, and L is the father of P, K is the sister of P's father (father's sister).

Explanation

The positional values of the letters in the alphabetical series are used to determine the pattern. For the clusters JNP, CGI, and RVX, the difference between consecutive letters is +4 and +2. For example, J (10) + 4 = N (14), and N (14) + 2 = P (16). Similarly, C (3) + 4 = G (7), and G (7) + 2 = I (9). Also, R (18) + 4 = V (22), and V (22) + 2 = X (24).

In contrast, the cluster HKM follows a different pattern where the positional difference is +3 and +2, because H (8) + 3 = K (11), and K (11) + 2 = M (13). This makes HKM the odd one out.

Explanation

The relationship between the numbers is defined by the formula: Second number = First number × 12

Applying this formula to the given pairs: 13 × 12 = 156 22 × 12 = 264

Following the same logic for 31: 31 × 12 = 372

Explanation

The given series consists of a repeating 9-letter pattern: aazbbyccx. Repeating this pattern four times forms a 36-letter sequence:

aazbbyccxaazbbyccxaazbbyccxaazbbyccx

By comparing this sequence with the given series, we can identify the letters that fill the blanks:

a [a] z b [b] y c [c] x [a] a z [b] b y c c [x] a a [z] b b [y] c c x [a] a z [b] b y [c] c x

The sequence of letters in the blanks is abcabxzyabc, which corresponds to the first option.

Explanation

In the letter cluster JMP, the alphabetical positions of the letters are J = 10, M = 13, and P = 16. The positional differences between consecutive letters are J to M (+3) and M to P (+3). This +3, +3 pattern differs from the +3, +4 pattern shared by the remaining letter clusters, where the first two letters differ by 3 positions and the last two differ by 4 positions.

Explanation

By substituting the correct mathematical operators into the given expression, where B represents ×, C represents +, A represents ÷, and D represents -, the equation becomes:

5 × 5 + 216 ÷ 9 - 3

Applying the BODMAS rule:

First, perform the division: 216 ÷ 9 = 24

Next, perform the multiplication: 5 × 5 = 25

Now, substitute these values back into the equation: 25 + 24 - 3

Finally, perform the addition and subtraction: 49 - 3 = 46

Explanation

Comparing the words TWIN and WING, the common letters are W, I, and N. The corresponding common digits in their codes 2359 and 5302 are 2, 3, and 5. By eliminating these common elements, the unique letter in TWIN is T, which corresponds to the remaining unique digit 9 in the code 2359.

Explanation

Correct Answer: B

To find the day of the week on 19 December 2021, we calculate the total number of odd days between 18 January 2013 and 19 December 2021.

First, calculate the odd days between 18 January 2013 and 18 January 2021: The number of years is 8 years (2021 − 2013 = 8). Among these, there are 2 leap years (2016 and 2020) and 6 ordinary years. Odd days from leap years = 2 × 2 = 4 Odd days from ordinary years = 6 × 1 = 6 Total odd days from years = 4 + 6 = 10 odd days.

Next, calculate the odd days from 18 January 2021 to 19 December 2021: Remaining days in January = 13 days (6 odd days) February = 28 days (0 odd days) March = 31 days (3 odd days) April = 30 days (2 odd days) May = 31 days (3 odd days) June = 30 days (2 odd days) July = 31 days (3 odd days) August = 31 days (3 odd days) September = 30 days (2 odd days) October = 31 days (3 odd days) November = 30 days (2 odd days) December = 19 days (5 odd days) Total odd days for this period = 6 + 0 + 3 + 2 + 3 + 2 + 3 + 3 + 2 + 3 + 2 + 5 = 34 odd days.

Now, sum the total odd days: Total odd days = 10 + 34 = 44 odd days. Dividing 44 by 7 gives a remainder of 2 odd days (44 = 6 × 7 + 2).

Since 18 January 2013 was Friday, we add 2 odd days to Friday: Friday + 2 days = Sunday.

Explanation

The numbers in each set follow the mathematical relation where the sum of the first and second numbers equals three times the third number.

First number + Second number = 3 × Third number

Applying this relation to the given sets: For (25, 8, 11): 25 + 8 = 33, which is equal to 3 × 11 = 33. For (28, 8, 12): 28 + 8 = 36, which is equal to 3 × 12 = 36.

Applying the same relation to the set in option C, which is (17, 7, 8): 17 + 7 = 24, which is equal to 3 × 8 = 24.

Explanation

The logic of the analogy is that each letter in the first group is shifted backward by 4 positions in the alphabetical order to obtain the corresponding letter in the second group.

Applying this rule, the position values of the letters are: C (3) - 4 = 25 (Y, using cyclic order) E (5) - 4 = 1 (A) H (8) - 4 = 4 (D) M (13) - 4 = 9 (I)

Applying the same logic to OQTY: O (15) - 4 = 11 (K) Q (17) - 4 = 13 (M) T (20) - 4 = 16 (P) Y (25) - 4 = 21 (U)

This yields the letter group KMPU.
