Explanation

By converting each letter to its corresponding numerical position in the English alphabet where A = 1, B = 2, and so on, the sum of the numerical values of the letters in each of the first three letter groups is exactly 26. For HOC, the sum of the letter positions is 8 + 15 + 3 = 26. For KMB, the sum of the letter positions is 11 + 13 + 2 = 26. For FSA, the sum of the letter positions is 6 + 19 + 1 = 26. For PDW, the sum of the letter positions is 16 + 4 + 23 = 43, which does not follow this pattern. This makes PDW the odd letter group.

Explanation

The number 352 is not divisible by 7, unlike the other numbers which are all perfectly divisible by 7.

Explanation

In the standard pattern for these numbers, the third digit is equal to the sum of the first two digits, and the fourth digit is equal to the product of the first two digits. For the number 2270, the sum of the first two digits is 2 + 2 = 4, but the third digit is 7. Similarly, the product of the first two digits is 2 × 2 = 4, but the fourth digit is 0. Since 2270 violates this mathematical rule, it is the odd number.

Explanation

The given series represents a logical hierarchy of physical and astronomical structures arranged in decreasing order of their size and scale of containment. The Universe is the largest entity, which encompasses multiple Galaxies. A Galaxy is a smaller constituent that contains various Solar systems. Following this descending order of cosmological scale, the next level of containment within a Solar system is a planet, which is represented by the World.

Explanation

The series follows a pattern where the positional values of the letters within each three-letter group increase by 3.

A (1) + 3 = D (4), and D (4) + 3 = G (7) I (9) + 3 = L (12), and L (12) + 3 = O (15) Q (17) + 3 = T (20), and T (20) + 3 = W (23)

The connection between consecutive groups is that the first letter of each group is 2 positions ahead of the last letter of the preceding group:

G (7) + 2 = I (9) O (15) + 2 = Q (17)

Following this rule, the first letter of the missing term is: W (23) + 2 = Y (25)

Applying the +3 progression within the group starting with Y: Y (25) + 3 = B (28, which cycles back to 2 in the 26-letter alphabet) B (2) + 3 = E (5)

This results in the term YBE.

Explanation

The series follows a specific alphabetical pattern for each corresponding letter position in the terms.

The first letters increase by two positions in alphabetical order, where B → D (+2) and D → F (+2), making the next first letter F + 2 = H.

The second letters increase by one position in alphabetical order, where M → N (+1) and N → O (+1), making the next second letter O + 1 = P.

The third letters decrease by one position in alphabetical order, where X → W (-1) and W → V (-1), making the next third letter V - 1 = U.

Combining these steps, the next term in the sequence is HPU.

Explanation

The given series follows a multiplicative pattern where each term is obtained by multiplying the preceding term with consecutive integers starting from 2. The progression of the terms is calculated as follows: the first term is 5, the second term is 5 × 2 = 10, the third term is 10 × 3 = 30, and the fourth term is 30 × 4 = 120. Following this pattern of multiplying by 2, 3, 4, and then 5, the next term in the series is 120 × 5 = 600.

Explanation

According to Statement I, petrol prices are increasing in the economy. An increase in the price of a commodity indicates a price rise or inflation hitting that commodity. Therefore, Conclusion I directly follows from the first statement.

Conclusion II suggests that the increase in petrol prices is due to rising demand not being met by supply at the same rate. Since the statements provide no information regarding the demand or supply of petrol in the economy, this represents an external assumption and does not follow from the given information. Thus, only Conclusion I follows.

Explanation

Let us represent the relationship between the individuals using inequality symbols.

From the first statement, A has more money than E but less than B, which gives the inequality: B > A > E

From the second statement, C has more money than D but less than E, which gives the inequality: E > C > D

By combining these two inequalities, we obtain the complete order: B > A > E > C > D

From this combined relation, B has the most money, making B the richest.

Explanation

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

Comparing the first letter of all words, they all start with S.

Comparing the second letter, Senate, Senior, and Serious have e, whereas Statesman has t. Since e comes before t, Statesman (iv) will be the last word in the sequence.

Comparing the third letter of Senate, Senior, and Serious, we have n in Senate and Senior, and r in Serious. Since n comes before r, Serious (i) comes after Senate and Senior.

Finally, comparing Senate (iii) and Senior (ii) at their fourth letter, we have a in Senate and i in Senior. Since a comes before i, Senate (iii) comes before Senior (ii).

Arranging them in this sequence gives Senate (iii), Senior (ii), Serious (i), and Statesman (iv).

Explanation

The letters of the word OCEAN are shifted forward by increasing consecutive integers from 1 to 5:

O (15) + 1 = P (16) C (3) + 2 = E (5) E (5) + 3 = H (8) A (1) + 4 = E (5) N (14) + 5 = S (19)

Applying the same logic to the word RIVER:

R (18) + 1 = S (19) I (9) + 2 = K (11) V (22) + 3 = Y (25) E (5) + 4 = I (9) R (18) + 5 = W (23)

Explanation

Substituting the operators as defined by the mathematical operations: "x" represents division (÷) "-" represents multiplication (×) "+" represents subtraction (-) "÷" represents addition (+)

The given expression is: 240 x 12 - 6 + 29 ÷ 42

Replacing the symbols with their corresponding operators: 240 ÷ 12 × 6 - 29 + 42

Applying the BODMAS rule:

First, perform the division: 240 ÷ 12 = 20

Now, substitute this value back into the expression: 20 × 6 - 29 + 42

Next, perform the multiplication: 20 × 6 = 120

Now, substitute this value back into the expression: 120 - 29 + 42

Finally, perform the addition and subtraction: 120 + 42 - 29 = 162 - 29 = 133

Explanation

Replacing the letters with their respective mathematical operators as given: L represents ÷ S represents × V represents - M represents +

The expression 36 L 9 S 8 V 7 M 5 becomes: 36 ÷ 9 × 8 - 7 + 5

Applying the BODMAS rule: First, perform the division: 36 ÷ 9 = 4

This simplifies the expression to: 4 × 8 - 7 + 5

Next, perform the multiplication: 4 × 8 = 32

This simplifies the expression to: 32 - 7 + 5

Finally, perform addition and subtraction from left to right: 32 - 7 + 5 = 25 + 5 = 30

Explanation

When the letters from the option cbaac are sequentially placed in the gaps of the series, the completed pattern is:

bca bca bca bca

This forms a perfect repeating pattern of the three-letter block bca repeated four times:

The first blank is filled with c, completing the first block as bca. The second blank is filled with b and the third blank with a, forming the second block as bca. The fourth blank is filled with a, forming the third block as bca. The fifth blank is filled with c, completing the fourth block as bca.

Explanation

Let the starting point be at coordinates (0, 0), where the positive y-axis represents the north, the negative y-axis represents the south, the positive x-axis represents the east, and the negative x-axis represents the west.

Vedit starts facing east. He turns right (which is towards the south) and walks 50 m, reaching the coordinate (0, -50). Next, he turns right again (which is towards the west) and walks 25 m, reaching (-25, -50). He then walks 10 m to the north, shifting his coordinates to (-25, -40). Finally, he walks 20 m to the east, bringing his final position to (-5, -40).

Since both the x-coordinate (-5) and the y-coordinate (-40) are negative, his final position lies in the south-west quadrant relative to his starting point of (0, 0).

Explanation

The word BOARD is coded using the row number followed by the column number for each of its letters.

For the letter B, in Matrix-II, row 7 and column 7 intersect at B, giving the code 77.

For the letter O, in Matrix-I, row 1 and column 3 intersect at O, giving the code 13.

For the letter A, in Matrix-I, row 2 and column 0 intersect at A, giving the code 20.

For the letter R, in Matrix-II, row 5 and column 7 intersect at R, giving the code 57.

For the letter D, in Matrix-II, row 8 and column 5 intersect at D, giving the code 85.

Combining these values yields the complete sequence 77, 13, 20, 57, 85.

Explanation

The girl in the photograph is the only daughter of Rajesh's father. The daughter of one's father is their sister. Since Rajesh is the sibling of this girl, he is related to her as her brother.

Explanation

A school is a place designated for studying and acquiring knowledge. Following the same relationship, a laboratory is a place designated for conducting scientific experiments.

Explanation

The relationship between the words is based on reversing the order of the letters of the given word.

When the letters of the word MANAGEMENT are written in reverse order: M - A - N - A - G - E - M - E - N - T becomes T - N - E - M - E - G - A - N - A - M.

Explanation

In this analogy, each letter of the first term is replaced by its opposite letter in alphabetical order, such that the sum of the alphabetical positions of the paired letters is 27.

W (23) + D (4) = 27 E (5) + V (22) = 27 F (6) + U (21) = 27 H (8) + S (19) = 27 Y (25) + B (2) = 27

Applying the same pattern to SFCLD:

S (19) is replaced by H (8) since 19 + 8 = 27. F (6) is replaced by U (21) since 6 + 21 = 27. C (3) is replaced by X (24) since 3 + 24 = 27. L (12) is replaced by O (15) since 12 + 15 = 27. D (4) is replaced by W (23) since 4 + 23 = 27.

Explanation

The relationship between the first and the second term is given by the formula: First term² ÷ 2 = Second term

For the first pair: 8² ÷ 2 = 64 ÷ 2 = 32

Applying the same mathematical logic to the second pair: 6² ÷ 2 = 36 ÷ 2 = 18

Explanation

A gallon is a unit used to measure volume or liquid capacity, whereas the other terms represent units of mass or weight.

Explanation

The alphabetical positions of the letters in each group are related such that the difference between the position of the first letter and the position of the second letter equals the position of the third letter. For the letter group TSE, the alphabetical positions of the letters are T = 20, S = 19, and E = 5. Calculating the difference gives 20 − 19 = 1, which corresponds to the letter A. Since the third letter is E instead of A, this group does not follow the established rule.

Explanation

The number 1050 is the odd one out because it is not divisible by 11, whereas all the other numbers in the set are divisible by 11. Applying the divisibility rule of 11 to 1050, the difference between the sum of the digits at the odd positions and the even positions is (1 + 5) - (0 + 0) = 6. Since 6 is not divisible by 11, 1050 is not divisible by 11, unlike the other three numbers which all have a difference of 0 and are thus multiples of 11.

Explanation

In the other numbers, the product of the first two digits is equal to the number formed by the last two digits, as seen in 4 × 8 = 32, 6 × 7 = 42, and 5 × 7 = 35. For 7855, the product of the first two digits is 7 × 8 = 56, which is not equal to the last two digits 55.

Explanation

The given sequence represents the components of the electromagnetic spectrum arranged in order of increasing wavelength (or decreasing frequency and energy). Gamma rays have the shortest wavelength, followed by X-rays and ultraviolet rays. The portion of the electromagnetic spectrum that lies immediately between ultraviolet rays and infrared rays is visible light.

Explanation

Each term in the series follows an increasing addition pattern of consecutive odd numbers for both the first and second letters.

Converting the letters to their corresponding numerical positions in the alphabet:

First letter sequence: X (24), Y (25), B (2), G (7) The differences between consecutive letters are: 24 + 1 = 25 (Y) 25 + 3 = 2 (B, since 28 - 26 = 2) 2 + 5 = 7 (G) Following this pattern, the next letter is obtained by adding 7: 7 + 7 = 14, which corresponds to N.

Second letter sequence: T (20), U (21), X (24), C (3) The differences between consecutive letters are: 20 + 1 = 21 (U) 21 + 3 = 24 (X) 24 + 5 = 3 (C, since 29 - 26 = 3) Following this pattern, the next letter is obtained by adding 7: 3 + 7 = 10, which corresponds to J.

Combining the two letters gives the next term in the series.

Explanation

The series follows a specific increment pattern in the alphabetical positions of both the first and second letters of each term.

For the first letter of each term, the alphabetical positions increase by +4, +5, +6, and then +7: O (15) + 4 = S (19) S (19) + 5 = X (24) X (24) + 6 = D (30, which is 4 in the 26-letter cycle) D (4) + 7 = K (11)

For the second letter of each term, the alphabetical positions follow the same increments of +4, +5, +6, and +7: P (16) + 4 = T (20) T (20) + 5 = Y (25) Y (25) + 6 = E (31, which is 5 in the 26-letter cycle) E (5) + 7 = L (12)

Applying this progression, the next term in the series is KL.

Explanation

The series progresses by dividing each term by 2 to obtain the next term.

76 ÷ 2 = 38 38 ÷ 2 = 19 19 ÷ 2 = 9.5 9.5 ÷ 2 = 4.75

Applying this division pattern to the final known term yields the next number in the series.

Explanation

In logical reasoning, a conclusion must be a direct, unavoidable deduction from the given statements. The statements only describe the structural mechanism of the dual GST model in India, explaining how the center and states simultaneously levy tax on a common base of goods and services. The statements make no mention of the socio-economic impact on the common man, nor do they discuss or imply any increase in clarity regarding the state and central tax components. Since both conclusions introduce external assumptions that are not supported by the premises, neither conclusion I nor II follows.

Explanation

Let the price of one eraser be x and the price of one pen be y.

From the purchases made by Rajan and Manu, we can set up the following system of linear equations: 3x + 5y = 105 4x + 6y = 130

To find the price of an eraser (x), we eliminate y by multiplying the first equation by 6 and the second equation by 5: 18x + 30y = 630 20x + 30y = 650

Subtracting the first modified equation from the second: 2x = 20 x = 10

Explanation

To arrange the words in the sequence in which they occur in a dictionary, we compare their letters from left to right. All four words begin with the letter A. Comparing their second letters:

Accentuate has the second letter c. Agent has the second letter g. Argentine has the second letter r. Assiduous has the second letter s.

Alphabetically, the order of these second letters is c, g, r, and s. Therefore, the words in dictionary order are Accentuate (iv), Agent (i), Argentine (ii), and Assiduous (iii), resulting in the sequence iv, i, ii, iii.

Explanation

In this coding-decoding pattern, each letter is directly substituted with a specific symbol based on its position in the given words:

From the word FIRST, which is represented by five symbols in the original code: F is coded as @ I is coded as # R is coded as S is coded as ! T is coded as ?

From the word EYE (written as ^^): E is coded as Y is coded as * E is coded as To write the word TYRE, each letter is replaced with its corresponding symbol: T is replaced by ? Y is replaced by * R is replaced by E is replaced by Combining these in order gives the code ?^.

Explanation

The pattern in each column follows the relation:

(First row number)² + (Second row number)² = Third row number

Applying this relation to each column:

First column: 12² + 16² = 144 + 256 = 400

Second column: 13² + 17² = 169 + 289 = 458

Third column: 11² + x² = 221 121 + x² = 221 x² = 221 - 121 x² = 100 x = 10

Explanation

Substituting the mathematical operators as per the given instructions: B represents ÷ A represents - C represents + D represents ×

The given expression: 411 B 3 A 29 C 53 D 20

Becomes: 411 ÷ 3 - 29 + 53 × 20

Applying the BODMAS rule, perform division and multiplication first: 411 ÷ 3 = 137 53 × 20 = 1060

Now substitute these values and perform the remaining operations: 137 - 29 + 1060 = 108 + 1060 = 1168

Explanation

The given series contains 12 letters which can be divided into three repeating groups of four letters each. By sequentially substituting the letters O, E, P, and N into the gaps, we get:

PEON PEON PEON

This forms a continuous repeating pattern of the word PEON. Therefore, the required set of letters to complete the series is OEPN.

Explanation

Let the starting point, which is Heera's home, be at the coordinates (0, 0). Walking 10 km towards the east positioning her at (10, 0). Taking a left turn from an easterly direction means turning north. Walking 20 km further north brings her to her college, which is located at (10, 20).

To determine the direction of her home (0, 0) relative to her college (10, 20), we look from the college's position. Moving from (10, 20) back to (0, 0) requires traveling south and west. Consequently, the home lies in the South-West direction relative to the college.

Explanation

To find the relationship, we can break down the statement made by the boy step-by-step.

First, identify my father's only brother-in-law. A father's brother-in-law is the brother of the father's wife, which makes him the boy's maternal uncle.

Second, the statement says the girl is the daughter of this maternal uncle.

The daughter of one's uncle is a cousin, which means the girl is the boy's cousin.

Explanation

The Tropic of Cancer is a major circle of latitude located at approximately 23.5° North of the Equator. Similarly, the Prime Meridian is the reference line of longitude, designated as 0° longitude, which passes through the Royal Observatory in Greenwich, London, and divides the Earth into the Eastern and Western Hemispheres. This completes the analogy by linking the specific geographical reference line to its corresponding coordinate type.

Explanation

The relationship between the words is that the second word is written in the reverse order of the first word. Reversing the letters of the word VANISH (V-A-N-I-S-H) from right to left gives HSINAV, which corresponds to option C.

Explanation

Each letter in the first group is shifted forward by two positions in the alphabetical order to obtain the corresponding letter in the second group.

H + 2 = J N + 2 = P P + 2 = R

Applying the same pattern to QRS:

Q + 2 = S R + 2 = T S + 2 = U

This gives the related letters as STU.

Explanation

The relationship between the numbers is defined by the formula: (n + 1)² = result

Applying this logic to the first pair: (14 + 1)² = 15² = 225

Applying the same logic to the second pair: (17 + 1)² = 18² = 324

Explanation

A bridge is designed to facilitate horizontal movement across an obstacle, such as a river, railway, or road, connecting two points on a similar level. The other items are all mechanisms or structures designed specifically for vertical movement, allowing a person to ascend or descend between different heights or floors. This makes a bridge the odd one out.

Explanation

The alphabetical positions of the letters in JLO are J = 10, L = 12, and O = 15. This group follows an increasing sequence with differences of +2 and +3, whereas the other letter groups follow a consistent decreasing sequence with a constant difference of -2.

Explanation

In the number 9842, the sum of the first and last digits is 9 + 2 = 11, while the sum of the middle two digits is 8 + 4 = 12. Since 11 is not equal to 12, this number does not follow the pattern of the other options where the sum of the outer digits equals the sum of the inner digits.

Explanation

The number 1728 is a perfect cube, equal to 12³ (12 × 12 × 12 = 1728). This mathematical property distinguishes it from the rest of the given numbers, which are not perfect cubes.

Explanation

The series represents different types of ecological conservation areas arranged in an increasing sequence of geographical size, scope, and complexity of biodiversity protection. A zoo is a small, ex-situ captive environment; a national park is a larger, strictly protected in-situ habitat; a wildlife sanctuary is a larger reserve designated for specific species; and a biosphere reserve is the largest, most comprehensive category encompassing multiple ecosystems, sustainable use zones, and often containing national parks and sanctuaries within it.

Explanation

Each letter in the triplets follows a specific arithmetic pattern based on its alphabetical position:

First letter: L → N → P → R The positions increase by +2: 12 → 14 → 16 → 18 (R).

Second letter: M → P → S → V The positions increase by +3: 13 → 16 → 19 → 22 (V).

Third letter: N → P → R → T The positions increase by +2: 14 → 16 → 18 → 20 (T).

Combining these changes gives the next term as RVT.

Explanation

Correct Answer: D

The series is formed by two independent patterns for the first and second letters of each term.

For the first letter of each term, the alphabetical positions are: F is 6 H is 8 (6 + 2) K is 11 (8 + 3) O is 15 (11 + 4) Following this pattern of increasing increments (+2, +3, +4, +5), the next letter is obtained by adding 5 to O (15), which gives T (20).

For the second letter of each term, the alphabetical positions are: D is 4 F is 6 (4 + 2) H is 8 (6 + 2) J is 10 (8 + 2) Following this constant increment pattern of +2, the next letter is obtained by adding 2 to J (10), which gives L (12).

Combining the two letters yields TL.

Explanation

The pattern in the series is obtained by multiplying each term by 3 and then adding 3 to get the next term.

First term to second term: 1 × 3 + 3 = 6

Second term to third term: 6 × 3 + 3 = 21

Third term to fourth term: 21 × 3 + 3 = 66

Applying the same logic to find the missing term: 66 × 3 + 3 = 198 + 3 = 201

Alternatively, the differences between consecutive terms form a geometric progression with a common ratio of 3: 6 - 1 = 5 21 - 6 = 15 (which is 5 × 3) 66 - 21 = 45 (which is 15 × 3)

The next difference must be: 45 × 3 = 135

Adding this difference to the last term gives: 66 + 135 = 201
