Explanation

The coding logic follows a repetitive pattern of adding 2 and subtracting 3 from the numerical positions of the letters in the alphabet. For the word GONE, the transformations are G(7) + 2 = 9(I), O(15) - 3 = 12(L), N(14) + 2 = 16(P), and E(5) - 3 = 2(B).

Applying this +2, -3 pattern to the word CRIB: C(3) + 2 = 5(E) R(18) - 3 = 15(O) I(9) + 2 = 11(K) B(2) - 3 = 25(Y)

When subtracting 3 from B, the sequence moves backward through the alphabet: B → A → Z → Y. Thus, the resulting code is EOKY.

Explanation

The given problem involves decoding a symbolic expression by substituting signs with mathematical operators and applying the BODMAS rule. Based on the logic of the code language, the expression 107 @ 3 @ 64 @ 8 @ 2 @ 9 is solved by assigning multiplication, subtraction, and division to the symbols.

Substituting the operators into the expression: 107 × 3 - 64 ÷ 8 - 2 × 9

Following the BODMAS order of operations (Brackets, Orders, Division, Multiplication, Addition, Subtraction):

Step 1: Perform the division. 64 ÷ 8 = 8 The expression becomes: 107 × 3 - 8 - 2 × 9

Step 2: Perform the multiplications. 107 × 3 = 321 2 × 9 = 18 The expression becomes: 321 - 8 - 18

Step 3: Perform the subtractions from left to right. 321 - 8 = 313 313 - 18 = 295

The calculation yields a result of 295, which corresponds to the value given in the code.

Explanation

The pattern follows the logic that the result is obtained by subtracting 4 from the actual product of the two numbers. In the first case, 12 × 16 = 192, and 192 - 4 = 188. Similarly, for the second case, 14 × 18 = 252, and 252 - 4 = 248. Following this same rule for the final expression, the product of 16 and 20 is 16 × 20 = 320. Subtracting 4 from this product yields 320 - 4 = 316.

Explanation

In the morning, the sun rises in the East, which means Raju initially walks in the East direction. When a person facing East takes a left turn, they face North. Upon taking another left turn from the North, the direction changes to West. Consequently, Raju is facing the West direction after his two turns.

Explanation

The statement establishes a direct conditional relationship between intelligence and creativity by asserting that the former should manifest as the latter. Assumption I is a necessary deduction because the statement explicitly bridges these two concepts, thereby confirming that a functional relationship exists between them. Assumption II follows within the internal logic of the premise because creativity is presented as the hallmark or expected standard of intelligence; in this context, the two attributes are treated as mutually inclusive qualities where the possession of one is logically tied to the presence of the other.

Explanation

The relationship in the given pair is between a physical quantity and its standard unit of measurement. Electric current is measured in Amperes. Applying the same logic to the second pair, weight is measured in Kilograms. Although weight is technically a force measured in Newtons in physics, in general aptitude and common scientific terminology, the kilogram is the standard metric unit associated with the measurement of an object's mass or weight.

Explanation

The relationship between the terms follows a specific pattern of alphabetical shifts. In the first pair ACXZ : BDWY, the first two letters move forward by one position in the alphabet, while the last two letters move backward by one position. Specifically, A +1 B, C +1 D, X -1 W, and Z -1 Y.

Applying this same logic to the sequence CEVX, we increment the first two letters and decrement the last two letters: C +1 D E +1 F V -1 U X -1 W

The transformation results in the sequence DFUW.

Explanation

The numbers in the given analogy follow the pattern n² + 1. For the first pair, 37 = 6² + 1 and 65 = 8² + 1. The relationship between the bases of the squares is an increase of 2, as 6 + 2 = 8.

Applying the same logic to the second pair, the number 50 can be expressed as 7² + 1. To find the related number, the base 7 must be increased by 2, resulting in 9. Calculating the value using the established pattern gives 9² + 1 = 81 + 1 = 82.

Explanation

Thermometer, barometer, and hygrometer are all scientific instruments used to measure physical properties such as temperature, atmospheric pressure, and humidity, respectively. Diameter, however, is a geometric dimension representing the length of a straight line passing through the center of a circle or sphere. It is a property of a shape rather than a measuring device.

Explanation

The pattern is determined by the numerical positions of the letters in the English alphabet, where A=1 and Z=26. In the given alternatives, the difference between the numerical rank of the first letter and the second letter is consistently 4. For the pair XS, the letters correspond to the numbers X = 24 and S = 19. The calculation 24 - 19 = 5 reveals a difference of 5. Since this value deviates from the uniform difference of 4 maintained by the other pairs, XS is the odd one out.

Explanation

The logic governing the numerical pairs involves a constant difference where the second number minus the first number equals 6 (y - x = 6). When examining the pair 76-84, the difference is calculated as 84 - 76 = 8. Because this resulting value of 8 differs from the uniform gap of 6 maintained throughout the rest of the entries, this pair is identified as the odd one.

Explanation

Dictionary order is determined by comparing words letter by letter from left to right according to the English alphabet. All five words begin with the prefix Emb. Comparing the fourth letter of each word, i in Embitter (3) appears first in the alphabet, followed by l in Emblem (4), then o in Embody (1), and finally r in both Embrace (2) and Embroidery (5). To differentiate between the two words starting with Embr, the fifth letters are compared; a in Embrace (2) precedes o in Embroidery (5). Following this alphabetical progression results in the sequence 3, 4, 1, 2, 5.

Explanation

The series follows a pattern where each term consists of three consecutive letters arranged in reverse alphabetical order. By observing the first letter of each triplet, there is a consistent jump of 3 positions in the alphabet: C is 3, F is 6, I is 9, and L is 12. Following this progression, the next starting letter is 12 + 3 = 15, which corresponds to the letter O. The triplet starting with O in reverse order is ONM.

Explanation

The series follows a multiplicative pattern where each subsequent term is obtained by multiplying the previous term by an integer that increases by 1 at each step. Starting from the first term, the progression is as follows:

2 × 5 = 10 10 × 6 = 60 60 × 7 = 420 420 × 8 = 3360

To find the missing term, the last term 3360 must be multiplied by the next consecutive integer in the multiplier sequence. Since the multipliers used were 5, 6, 7, and 8, the next multiplier is 9.

3360 × 9 = 30240

Explanation

To solve this blood relation problem, the statement can be broken down from the perspective of the speaker. The man refers to the only daughter of his mother-in-law. A mother-in-law is the mother of one's spouse; therefore, her only daughter is the man's wife. By substituting this into the original sentence, the statement becomes "Her mother is my wife." If the woman's mother is the man's wife, then the woman is the man's daughter. This establishes that the man is the father of the woman.

Explanation

Let the five positions from left to right be 1, 2, 3, 4, and 5.

Q is fourth from N: In a row of five, this implies that if N is the starting point (1st), Q is the 4th child in the count. This allows for pairs at positions (1, 4) or (2, 5). M is left of N: This condition rules out N being in position 1, as there would be no space for M. Therefore, N must be in position 2, and consequently, Q is in position 5 (counting 2 as 1st, 3 as 2nd, 4 as 3rd, and 5 as 4th). Position of M: Since M is to the left of N (position 2), M must occupy position 1. O is third from M: Counting from M at position 1, the 3rd child is at position 3 (1, 2, 3). Thus, O is in position 3. Position of P: The only remaining position is 4, which is occupied by P. This satisfies the condition that P is to the left of Q (position 5).

The arrangement from left to right is: M(1), N(2), O(3), P(4), Q(5).

To find the position from the right: 1st from right: Q 2nd from right: P

P is in the second position from the right.

Explanation

The word GREEN requires the letter R for its formation. Upon examining the source word INTELLIGENCE, it contains the letters I, N, T, E, L, G, and C, but it does not contain the letter R. Since the letter R is missing from the original word, GREEN cannot be constructed.

Explanation

The coding pattern involves shifting each letter of the word forward by one position in the alphabetical sequence. In the word GOAT, the transformation is G + 1 = H, O + 1 = P, A + 1 = B, and T + 1 = U, resulting in the code HPBU. Applying this identical logic to the word FROG, the letters are incremented as follows: F + 1 = G, R + 1 = S, O + 1 = P, and G + 1 = H. Following this +1 shift rule, FROG is coded as GSPH.

Explanation

Following the standard mathematical code for this exam series, the symbols represent specific operations: α represents division (÷), Φ represents subtraction (-), and θ represents multiplication (×). Additionally, in the provided expression, the string 594 is a typographical representation of 5 θ 4 (i.e., 5 × 4), and a is used for α.

Substitute the operations into the expression: 8900 ÷ 100 - 5 × 4 - 121 ÷ 11

Applying the BODMAS rule (Division and Multiplication before Subtraction): First, perform the divisions: 8900 ÷ 100 = 89 121 ÷ 11 = 11

Next, perform the multiplication: 5 × 4 = 20

Substitute these values back into the expression: 89 - 20 - 11

Finally, perform the subtractions: 89 - 20 = 69 69 - 11 = 58

Explanation

The system follows a cyclic permutation of digits where the product a × b × c is rearranged into the number bca. In the first equation 1 × 2 × 3 = 231, the first digit 1 moves to the last position, while the second and third digits 2 and 3 shift forward. Similarly, in 3 × 4 × 5 = 453, the first digit 3 moves to the end and 45 moves to the front. Applying this logic to 5 × 6 × 7, the first digit 5 is placed at the end, and the remaining digits 6 and 7 are placed at the beginning, resulting in the number 675.

Explanation

The numbers are arranged in columns where the fourth row is calculated by adding the numbers in the first and second rows and then multiplying the sum by the number in the third row. The mathematical relationship can be expressed by the formula (Row 1 + Row 2) × Row 3 = Row 4.

In the first column, adding 4 and 3 results in 7, which multiplied by 2 equals 14. In the second column, adding 3 and 5 results in 8, which multiplied by 2 equals 16. Following this consistent pattern for the third column, adding 6 and 4 results in 10, which when multiplied by 3 gives 30.

Explanation

Rajneesh begins by walking in the North direction. Taking a left turn from North shifts his orientation 90 degrees counter-clockwise, which means he is then facing West. While walking West, he takes a right turn, which is a 90-degree clockwise shift. This second turn cancels out the directional change of the first turn. Since a left turn followed by a right turn results in a net change of zero degrees, his final facing direction remains the same as his initial direction, which is North.

Explanation

The statements can be analyzed using set theory where the set of books is a subset of trees and the set of trees is a subset of lions. This relationship is expressed as Books ⊂ Trees ⊂ Lions. According to the transitive law of syllogisms, because all books are contained within the category of trees and all trees are contained within the category of lions, every member of the book category must also be a member of the lion category. This validates Conclusion I, All books are lions. Furthermore, if the entire set of books is contained within the set of lions, then the intersection between lions and books is non-empty and encompasses the entire set of books. In formal logic, the universal affirmative statement All books are lions implies the particular affirmative statement Some lions are books, which validates Conclusion IV. Thus, both Conclusions I and IV are logically certain based on the provided premises.

Explanation

The analogy established in the question follows a part-to-whole relationship. The head is a physical constituent and a biological part of the human body. Similarly, an arc is defined as a portion of the circumference or a part of a circle. The relationship between the two terms in the first pair is identical to the relationship between the two terms in the second pair, where the first element is a segment or component of the entire structure represented by the second element.

Explanation

The logic follows a pattern where each letter in the first group is shifted backward by 2 positions in the English alphabetical order to obtain the corresponding letter in the second group.

Applying this pattern to the first pair: P (16) - 2 = N (14) Z (26) - 2 = X (24) Q (17) - 2 = O (15) W (23) - 2 = U (21)

Applying the same -2 shift to FISK: F (6) - 2 = D (4) I (9) - 2 = G (7) S (19) - 2 = Q (17) K (11) - 2 = I (9)

The resulting letters form the sequence DGQI.

Explanation

The relationship between the numbers follows the mathematical pattern y = 2x + 5, where x represents the first number and y represents the second number in the pair. For the first pair, 7 × 2 + 5 = 14 + 5 = 19. Applying this same logic to the second pair, we calculate 10 × 2 + 5 = 20 + 5 = 25.

Explanation

The words bigger, greater, and taller are all adjectives used to compare the physical dimensions, size, or magnitude of objects. They describe the spatial extent or scale of a subject. Conversely, faster is a comparative adjective that describes speed or the rate of motion over time, which belongs to a different category of measurement unrelated to physical size.

Explanation

In the given sequences, the letters in the first three options follow a consistent arithmetic progression where each subsequent letter is obtained by adding 4 to the numerical position of the preceding letter. For example, in AEIM, the positions are 1, 5, 9, 13; in BFJN, they are 2, 6, 10, 14; and in CGKO, they are 3, 7, 11, 15. In contrast, the sequence FDKN corresponds to the numerical positions 6, 4, 11, 14. The differences between these letters are -2, +7, and +3, which deviates from the uniform +4 increment pattern found in the other alternatives.

Explanation

The pair 100 – 30 is the odd one out because it does not satisfy the mathematical relation x = 3y + 5, where x is the first number and y is the second number. While the established pattern requires adding 5 to the product of the second number and 3, this pair results in 100 because it adds 10 to the product since 30 × 3 + 10 = 100. Applying the standard rule to the second number 30 would instead yield 30 × 3 + 5 = 95.

Explanation

To arrange the words in alphabetical order, we compare the letters of each word from left to right. All four words begin with the letter F. Comparing the second letter, Fabulous, Fantastic, and Fascinating all have a, while Forest has o. Since a comes before o in the alphabet, Forest is the last word in the sequence. Next, we compare the third letter of the remaining words: Fabulous has b, Fantastic has n, and Fascinating has s. In alphabetical order, b comes first, followed by n, and then s. This results in the sequence 4 (Fabulous), 3 (Fantastic), 2 (Fascinating), and finally 1 (Forest).

Explanation

The given letter series consists of fifteen positions with six gaps: a _ c a _ c _ d c _ d _ a d _. By sequentially placing the letters from the set ddaacc into these gaps, the series is completed as adcadcadcadcadc. This resulting sequence follows a clear periodic pattern where the three-letter block adc repeats itself five times without interruption. The first d fills the second position, the second d fills the fifth position, the first a fills the seventh position, the second a fills the tenth position, the first c fills the twelfth position, and the final c fills the fifteenth position to maintain the repeating triplet structure.

Explanation

The series is an alternating sequence composed of two distinct arithmetic progressions. The first progression consists of the terms at odd positions (1st, 3rd, and 5th), which are 1, 2, and 3. Each term in this sub-series increases by 1. The second progression consists of the terms at even positions (2nd, 4th, and 6th), which are 5, 6, and 7, also increasing by 1. The next number in the series is the 7th term, which belongs to the first progression. Following the pattern 1, 2, 3, the next term is 3 + 1 = 4.

Alternatively, the series can be solved by looking at the difference between consecutive terms. The operations follow a repeating pattern of +4 and -3. Specifically, 1 + 4 = 5, 5 - 3 = 2, 2 + 4 = 6, 6 - 3 = 3, and 3 + 4 = 7. Applying the next operation in the sequence, which is -3, we get 7 - 3 = 4.

Explanation

P and Q are sisters, meaning they are in the same generation. R and S are brothers. Since P's daughter is R's sister, it implies that P is the mother of R. Because R and S are brothers, P is also the mother of S. Q is the sister of P, and the sister of one's mother is a maternal aunt. Therefore, Q is the aunt of S.

Explanation

When the son was born, the father was 32 years old. After 7 years, the son's age becomes 7, and the father's age also increases by 7 years, making him 32 + 7 = 39 years old. The problem states that when the son attained the age of 7, the mother was 35 years old. The difference between the age of the father and the mother at that time is 39 - 35 = 4 years. Because the age gap between any two people remains constant over time, the difference between their ages is 4 years.

Explanation

The word COUNTER cannot be formed because it contains the letter R, which is not present in the given word ANNOUNCEMENTS. While all other letters required for COUNTER are available, the lack of the letter R makes the formation of this word impossible.

Explanation

The coding pattern follows a constant subtraction of 3 from the alphabetical position of each letter in the word. In the word RATION, the transformation is as follows: R(18) - 3 = O(15), A(1) - 3 = X(24), T(20) - 3 = Q(17), I(9) - 3 = F(6), O(15) - 3 = L(12), and N(14) - 3 = K(11).

Applying the same logic to LUMBER: L(12) - 3 = I(9) U(21) - 3 = R(18) M(13) - 3 = J(10) B(2) - 3 = Y(25) E(5) - 3 = B(2) R(18) - 3 = O(15)

By subtracting 3 from the positional value of each letter, the resulting code for LUMBER is IRJYBO.

Explanation

Based on the operator definitions provided, the expression 10 10 = 5 10 ? 50 @ 10 is translated into standard mathematical notation by replacing the symbols with their corresponding operations: * becomes ×, = becomes -, ? becomes +, and @ becomes ÷.

The substituted expression is 10 × 10 - 5 × 10 + 50 ÷ 10. Following the BODMAS rule, we perform division and multiplication before addition and subtraction:

50 ÷ 10 = 5 10 × 10 = 100 5 × 10 = 50

Replacing these values back into the expression gives 100 - 50 + 5. Solving from left to right, we get 50 + 5 = 55.

Explanation

The mathematical logic applied in this pattern involves calculating the sum of the two numbers and then dividing that sum by 3.

Formula: Result = (A + B)/(3)

Applying this to the given sets, (37 + 14) ÷ 3 = 51 ÷ 3 = 17, and (69 + 33) ÷ 3 = 102 ÷ 3 = 34. Similarly, for the third set, (91 + 125) ÷ 3 = 216 ÷ 3 = 72. Using this same principle for the final expression, the sum of 28 and 56 is 84, and dividing 84 by 3 results in 28.

Explanation

The logic follows a horizontal pattern where the difference between the second and first columns is multiplied by 2 to obtain the value in the third column.

In the first row: (56 - 21) × 2 = 35 × 2 = 70. In the second row: (87 - 45) × 2 = 42 × 2 = 84. In the third row: (180 - 115) × 2 = 65 × 2 = 130.

Explanation

The initial direction of travel is from North to South, meaning P is facing South. A right-angle turn to the right from the South direction changes the orientation to West. Subsequently, a second right-angle turn to the right from the West direction changes the orientation to North. Following these two successive 90-degree right turns, the final direction of movement is North.

Explanation

The first statement establishes a universal conditional relationship where the presence of dams is a sufficient condition for the absence of water problems. If a state has a dam, it is guaranteed to have no water problem. Conclusion II directly reflects this relationship because if every state with a dam faces no water problem, it logically follows that dams serve as a solution to such problems.

The second statement identifies a state that does not have a dam. According to formal logic, if P (dam) implies Q (no water problem), then the absence of P does not strictly necessitate the absence of Q. However, because the guaranteed protection against water problems is removed, it becomes possible for that state to experience a water problem. Conclusion I uses the modal verb may, which correctly identifies this logical possibility. Since both the direct functional inference and the logical possibility are supported by the premises, both conclusions follow.

Explanation

The relationship established in the first pair is based on the anatomical part of the body used for standing and locomotion. A foot is the terminal part of the leg of a man that supports the body weight and facilitates movement. Following the same logic, a hoof is the hard, keratinous covering at the end of the leg of a horse that performs the same function. Just as a human possesses feet, a horse is characterized by its hooves.

Explanation

The relationship follows the mathematical pattern n³ + n for consecutive integers n.

For the first pair, when n = 4, 4³ + 4 = 64 + 4 = 68. For the next integer n = 5, 5³ + 5 = 125 + 5 = 130.

For the second pair, the given number 222 corresponds to n = 6 because 6³ + 6 = 216 + 6 = 222. Following the sequence of consecutive integers, the missing value corresponds to n = 7. Calculating this value yields 7³ + 7 = 343 + 7 = 350.

Explanation

June consists of exactly 30 days. In the Gregorian calendar, June is categorized as a 30-day month, while the other months provided are categorized as 31-day months. This difference in the number of days is the specific criterion that differentiates it from the rest of the group.

Explanation

The letter group XUBU is the odd one out because it contains a repeated letter, with the letter U appearing twice. In contrast, all other options, CZHK, SENO, and MLAG, consist of four distinct letters where no character is repeated within the set. This internal repetition of a letter differentiates XUBU from the rest of the alternatives.

Explanation

The logic follows the pattern of pairs of consecutive perfect cubes, where the relationship is n³ : (n+1)³.

In option a: 1³ = 1 and 2³ = 8. In option b: 3³ = 27 and 4³ = 64. In option d: 7³ = 343 and 8³ = 512.

In option c: 5³ = 125, but the next consecutive perfect cube is 6³ = 216. Since the value provided is 218 instead of 216, this pair does not follow the established pattern of consecutive perfect cubes.

Explanation

To arrange the words in dictionary order, we compare them letter by letter from left to right. All four words begin with the same first three letters Fol. We then look at the fourth letter of each word: Foliage has i, Folk has k, and both Follicle and Follow have l. In alphabetical order, i comes before k, and k comes before l, which places Foliage (4) first and Folk (2) second. To determine the order between Follicle and Follow, we move to the fifth letter. Follicle has i while Follow has o. Since i precedes o in the alphabet, Follicle (1) comes before Follow (3). The final dictionary sequence is 4, 2, 1, 3.

Explanation

The series follows a pattern where each term is generated by multiplying the preceding term by 2 and then subtracting an incrementally increasing integer, starting from 1.

The calculation for each term is as follows: The second term is 8 × 2 - 1 = 15. The third term is 15 × 2 - 2 = 28. The fourth term is 28 × 2 - 3 = 53. Applying the same logic to find the missing term, we multiply the fourth term by 2 and subtract 4: 53 × 2 - 4 = 106 - 4 = 102.

Explanation

The missing term is found by examining the progression of each letter position in the triplets. In the first position, the sequence W, T, Q follows a pattern of subtracting 3 from the alphabetical rank: 23 - 3 = 20 (T) and 20 - 3 = 17 (Q). The next letter is 17 - 3 = 14, which is N. In the second position, the sequence F, G, H follows a constant increment of 1 (6, 7, 8), making the next letter 8 + 1 = 9, which is I. In the third position, the sequence B, D, G follows an increasing gap pattern where the first jump is +2 and the second is +3 (2 + 2 = 4 and 4 + 3 = 7). Following this logic, the next increment is +4, resulting in 7 + 4 = 11, which is the letter K.

Explanation

Using the average age formula, Teacher's Age = (New Average × New Total Strength) - (Old Average × Old Strength). Substituting the given values:

Teacher's Age = (22 × 20) - (21 × 19) Teacher's Age = 440 - 399 Teacher's Age = 41 years

Alternatively, using the increment method, the teacher's age is the new average plus the total increase distributed across the original group members. Teacher's Age = New Average + (Old Strength × Increase in Average) Teacher's Age = 22 + (19 × (22 - 21)) Teacher's Age = 22 + 19 = 41 years
