Explanation

By comparing the letters of the given words with their respective numerical codes, the code for each individual letter can be determined directly.

From the word LIAR coded as 5782, the letter A is coded as 8 and R is coded as 2.

From the word RANGE coded as 28641, the letter R is coded as 2, A is coded as 8, N is coded as 6, G is coded as 4, and E is coded as 1.

Using these established direct letter-to-digit correspondences: A corresponds to 8 R corresponds to 2 R corresponds to 2 A corresponds to 8 N corresponds to 6 G corresponds to 4 E corresponds to 1

Combining these in order for the word ARRANGE yields the code 8228641.

Explanation

The relationship in each column is established by multiplying the numbers in the second and third rows and adding twice the value of the fourth row to obtain the first row.

In Column 1: (2 × 3) + (4 × 2) = 6 + 8 = 14

In Column 2: (2 × 6) + (4 × 2) = 12 + 8 = 20

Applying the same logic to Column 3: (? × 5) + (3 × 2) = 16 5 × ? + 6 = 16 5 × ? = 10 ? = 2

Explanation

By substituting the signs as specified: becomes ÷

• becomes × ÷ becomes - × becomes +

Applying these changes to the equation 16 - 4 + 4 ÷ 2 × 6: 16 ÷ 4 × 4 - 2 + 6

According to the BODMAS rule, division is performed first: 16 ÷ 4 = 4 The expression becomes: 4 × 4 - 2 + 6

Next, multiplication is performed: 4 × 4 = 16 The expression becomes: 16 - 2 + 6

Finally, addition and subtraction are performed: 16 - 2 + 6 = 20

This value is equal to the right-hand side of the equation.

Explanation

The analogy represents the relationship between a shelter or home and the animal that inhabits it. A nest is the natural dwelling place of a bird. In the same manner, a den is the natural dwelling place of a lion.

Explanation

When we sequentially place the set of letters from option B (ighii) into the gaps of the given letter series, we get:

g h [i] i [g] h [h] i [i] g [i] i

This completed sequence can be divided into groups of four letters to reveal a systematic pattern:

g h i i / g h h i / i g i i / i

Each group of four letters is composed of the letters g, h, and i, with one of the letters repeating in a structured sequence to complete the pattern.

Explanation

Let the starting point of Aryan be the origin (0, 0).

Initially, Aryan is facing west. When he turns right, he faces north. Walking 20 m north brings him to the coordinates (0, 20).

From here, turning left means he faces west. Walking 10 m west brings him to (-10, 20).

Next, walking 7 m north brings him to (-10, 27).

Finally, walking 10 m west brings him to (-20, 27).

Comparing his final position (-20, 27) to his starting position (0, 0), the coordinates are in the negative x-direction (west) and the positive y-direction (north). Therefore, he is in the North-west direction relative to his starting point.

Explanation

The word COVER is represented by decoding each letter using the row-by-column format from the matrices.

For the letter C, row 0 and column 3 in Matrix-I intersect at C, which is represented as 03. For the letter O, row 3 and column 3 in Matrix-I intersect at O, which is represented as 33. For the letter V, row 8 and column 9 in Matrix-II intersect at V, which is represented as 89. For the letter E, row 5 and column 9 in Matrix-II intersect at E, which is represented as 59. For the letter R, row 1 and column 1 in Matrix-I intersect at R, which is represented as 11.

This yields the complete set of numbers 03, 33, 89, 59, 11.

Explanation

Let us analyze the statement made by the woman step by step.

The phrase "the only daughter of my mother" refers to the woman herself, as she is the speaker and her mother has only one daughter.

Substituting this back into the statement, "His son's mother" is the woman herself.

The mother of a man's son is that man's wife. Since the woman herself is the mother of the man's son, she is the wife of the man. Therefore, the man is the husband of the woman.

Explanation

The letters are related by dividing their alphabetical positions by 2.

For the first pair, NPR and GHI: N is the 14th letter of the alphabet, and 14 ÷ 2 = 7, which is G. P is the 16th letter of the alphabet, and 16 ÷ 2 = 8, which is H. R is the 18th letter of the alphabet, and 18 ÷ 2 = 9, which is I.

Applying the same pattern to TVX: T is the 20th letter of the alphabet, and 20 ÷ 2 = 10, which is J. V is the 22nd letter of the alphabet, and 22 ÷ 2 = 11, which is K. X is the 24th letter of the alphabet, and 24 ÷ 2 = 12, which is L.

Explanation

The relationship in the first pair AF : BE is based on alphabetical shifts: The first letter increases by 1 position (A to B). The second letter decreases by 1 position (F to E).

Applying the same logic to the second pair ? : DH: The first letter of the missing group must be 1 position before D, which is C. The second letter of the missing group must be 1 position after H, which is I.

This gives the term CI.

Explanation

The relationship between the numbers in the first pair is based on the square root function, where the second number is the square root of the first number.

√36 = 6

Applying this same mathematical relationship to the second pair gives:

√441 = 21

This satisfies the ratio relation as 21² equals 441.

Explanation

White is the odd one out because Violet, Indigo, and Blue are primary spectral colors of the visible light spectrum as represented in a rainbow (using the VIBGYOR acronym), whereas white is not a spectral color but rather the combination of all visible wavelengths of light.

Explanation

In the letters FHJ, the alphabetical positions are F = 6, H = 8, and J = 10, showing a constant difference of +2 between consecutive letters. This differs from the other letter groups, which all have a constant difference of +3 between consecutive letters.

Explanation

The number 512 is a perfect cube, since 8³ = 512. The other numbers are perfect squares, specifically 29² = 841, 24² = 576, and 17² = 289. Since 512 is not a perfect square, it is the odd one out.

Explanation

The number 852 is the odd one out because it is not divisible by 11, and the sum of its first and third digits (8 + 2 = 10) does not equal its middle digit (5), whereas the other numbers are divisible by 11 and have their middle digit equal to the sum of their outer digits.

Explanation

The given series lists the continents of the world. Asia, Africa, and North America are all major continents. Australia represents another continent, which logically continues and completes the sequence of world continents.

Explanation

The analogy represents the relationship between a legendary Indian sportsperson and the sport they played. V. V. S. Laxman is an iconic Indian cricketer who represented the national team. Similarly, Major Dhyan Chand was an legendary Indian sportsman widely regarded as one of the greatest field hockey players of all time, famous for his extraordinary ball control and leading India to three Olympic gold medals. Therefore, the sport associated with Dhyan Chand is Hockey.

Explanation

The positional values of the letters in the English alphabet are used to find the relationship.

T has a positional value of 20, and N has a positional value of 14. W has a positional value of 23, and Q has a positional value of 17.

Each letter of the first group is shifted forward by 3 positions to obtain the second group: 20 + 3 = 23 (W) 14 + 3 = 17 (Q)

Applying this same rule to BV: B has a positional value of 2, and V has a positional value of 22.

Adding 3 to each positional value: 2 + 3 = 5, which represents E 22 + 3 = 25, which represents Y

Explanation

The relationship established in the first pair, Convenient and Inconvenient, is one of antonyms. To maintain the same pattern for the second pair, the word that is opposite in meaning to Reveal must be selected. The antonym of Reveal is Conceal.

Explanation

The relation between the numbers in each pair follows the mathematical formula:

y = 3x²

Where x represents the first number and y represents the second number.

For the first pair, substituting x = 6: y = 3 × 6² = 3 × 36 = 108

Applying the same formula to the second pair, substituting x = 11: y = 3 × 11² = 3 × 121 = 363

Explanation

Prejudiced is the odd word out because it has a negative connotation, representing a biased, unfair, or subjective attitude that is not based on reason or actual experience. In contrast, the other words in the group represent positive, desirable qualities and moral values associated with honesty, truthfulness, and dependability.

Explanation

POM has letter positional values of P = 16, O = 15, and M = 13. The differences between the successive letters are -1 and -2 (16 - 1 = 15, and 15 - 2 = 13). This does not match the consistent pattern of -1 and -3 found in the rest of the letter groups.

Explanation

The number 263 is the only one in which the sum of the first and last digits (2 + 3 = 5) does not equal the middle digit (6). For the other numbers, the middle digit is equal to the sum of the first and third digits, making them divisible by 11, whereas 263 is not divisible by 11.

Explanation

The number 2437 does not follow the mathematical rule shared by the other alternatives. In the other numbers, the product of the first digit and the successor of the second digit (the second digit plus 1) equals the number formed by the last two digits. For 2437, this calculation results in 2 × (4 + 1) = 10, which does not equal the last two digits, 37.

Explanation

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

For the first letters, the alphabetical positions increase progressively by 1: D (4) → E (5) → F (6) → G (7)

For the second letters, the alphabetical positions increase by consecutive odd numbers starting from 9: P (16) + 9 = Y (25) Y (25) + 11 = 36, which corresponds to J (10) since 36 - 26 = 10 J (10) + 13 = W (23)

Combining the two results yields the next term in the series.

Explanation

The series represents types of residential dwellings arranged in increasing order of their size, grandeur, and luxury. A hut is the smallest and simplest type of house, followed by a cottage which is larger and more comfortable. A bungalow represents a much larger, more spacious, and luxurious independent home. Continuing this ascending order of size and splendor, a palace is the grandest and largest form of residence.

Explanation

By converting the letters to their alphabetical positions (A = 1, B = 2, ..., Z = 26):

For the first letter of each term: N (14) to S (19) is a difference of +5 S (19) to W (23) is a difference of +4 W (23) to Z (26) is a difference of +3 Following this decreasing difference pattern, the next increment must be +2. Adding 2 to Z (26) wraps around the alphabet to B (2).

For the second letter of each term: R (18) to W (23) is a difference of +5 W (23) to A (1 or 27) is a difference of +4 A (1) to D (4) is a difference of +3 Following the same decreasing difference pattern, the next increment must be +2. Adding 2 to D (4) gives F (6).

Combining these, the next term in the series is BF.

Explanation

The given series alternates between two-letter terms and single-letter terms. By converting the letters into their numerical positions in the English alphabet where A = 1, B = 2, up to Z = 26, the numerical values of the letters in each two-letter term add up to the position of the subsequent single-letter term.

Applying this rule:

For the first term EF: E = 5 and F = 6 5 + 6 = 11, which represents the letter K.

For the third term JK: J = 10 and K = 11 10 + 11 = 21, which represents the letter U.

For the fifth term OP: O = 15 and P = 16 15 + 16 = 31

Because there are only 26 letters in the alphabet, the positions wrap around cyclically. Therefore, the 31st position corresponds to 31 - 26 = 5. The letter at the 5th position of the English alphabet is E.

Explanation

The series is formed by adding consecutive multiples of 5 to each preceding term.

14 + 5 = 19 19 + 10 = 29 29 + 15 = 44

Following this pattern, the next difference must be 20. Adding 20 to the last term yields:

44 + 20 = 64

Explanation

By Statement (I), the empty set, denoted as ∅, is a subset of any set, which can be written as ∅ ⊆ S for any set S. Since any power set P(S) is itself a set, the empty set is logically a subset of the power set, meaning ∅ ⊆ P(S). This validates Conclusion (I) as a sound deduction derived from Statement (I).

In logical reasoning, a valid conclusion must be a new inference deduced from the premises rather than a mere repetition. Since Conclusion (II) is a verbatim repetition of Statement (II), it is not classified as a valid logical deduction.

Explanation

To find the day of the week on 19th September 2012 starting from 18th October 2011, we calculate the total number of days between these two dates.

The remaining days in October 2011 are 13 days (31 - 18). For the subsequent months, the number of days are: November 2011: 30 days December 2011: 31 days January 2012: 31 days February 2012: 29 days (since 2012 is a leap year) March 2012: 31 days April 2012: 30 days May 2012: 31 days June 2012: 30 days July 2012: 31 days August 2012: 31 days September 2012: 19 days (up to 19th September)

Adding all these days together: 13 + 30 + 31 + 31 + 29 + 31 + 30 + 31 + 30 + 31 + 31 + 19 = 337 days

Dividing 337 by 7 to determine the number of odd days: 337 = 48 × 7 + 1

This gives 1 odd day. Adding 1 day to Sunday results in Monday.

Explanation

To arrange the words in alphabetical dictionary order, we compare their letters from left to right. All four words share the first three letters, Tre.

Comparing the fourth letters: Treasure and Treat have a. Tremor has m. Trestle has s.

Since a comes before m, and m comes before s in the alphabet, Treasure and Treat will appear first, followed by Tremor, and then Trestle.

To determine the order between Treasure and Treat, we compare their fifth letters: Treasure has s. Treat has t.

Since s precedes t, Treasure comes before Treat.

Following this sequence, the correct dictionary order is Treasure (i), Treat (ii), Tremor (iii), and Trestle (iv).

Explanation

The coding pattern is based on reversing the order of the letters in the given word.

When the word EXCITED is written in reverse order, it becomes DETICXE.

Following the same logic, reversing the letters of the word KINLEY yields YELNIK.

Explanation

In each column, the product of the first two numbers is calculated, and then the digits of this product are reversed to obtain the third number.

For Column 1: 7 × 7 = 49 Reversing the digits of 49 gives 94.

For Column 2: 6 × 8 = 48 Reversing the digits of 48 gives 84.

For Column 3: 9 × 11 = 99 Reversing the digits of 99 gives 99.

Explanation

According to the given definitions, the symbols correspond to mathematical operations as follows: @ represents division (÷), # represents multiplication (×), represents addition (+), and % represents subtraction (-).

Substituting these operations into the expression: 136 ÷ 17 × 0 + 19 - 5

Applying the BODMAS rule, we perform division first: 136 ÷ 17 = 8

This reduces the expression to: 8 × 0 + 19 - 5

Next, we perform multiplication: 8 × 0 = 0

This reduces the expression to: 0 + 19 - 5

Finally, performing addition and subtraction yields: 19 - 5 = 14

Explanation

The series is formed by applying a specific pattern to each letter position of the terms.

For the first letters, the alphabetical positions increase by 2: D (4) → F (6) → H (8) → J (10).

For the second letters, the alphabetical positions increase by 4: A (1) → E (5) → I (9) → M (13).

For the third letters, the alphabetical positions decrease by 2: F (6) → D (4) → B (2) → Z (26).

Combining these results gives the term JMZ.

Explanation

The given letter series consists of 12 letters and can be divided into four groups of three letters each, following an alternating pattern of STR and TRS:

STR | TRS | STR | TRS

By sequentially placing the letters T, S, R, and R into the respective gaps, the series completes this repeating sequence.

Explanation

Starting by moving in the South direction, a left turn changes your heading to the East. A subsequent left turn changes your heading to the North. A final right turn from the North changes your facing direction back to the East.

Explanation

The code 88, 65, 20, 11, 24 represents the word MOVIE based on the rule where the first digit represents the row and the second digit represents the column of the respective matrix.

For the letter M, Row 8 and Column 8 of Matrix-II gives 88. For the letter O, Row 6 and Column 5 of Matrix-II gives 65. For the letter V, Row 2 and Column 0 of Matrix-I gives 20. For the letter I, Row 1 and Column 1 of Matrix-I gives 11. For the letter E, Row 2 and Column 4 of Matrix-I gives 24.

Explanation

Ajeet and his only sister represent the first generation of this family structure. Sourabh's mother is the daughter of Ajeet's sister, placing her in the second generation. Ritik's parent is the child of Ajeet, which also puts them in the second generation. Since the parents of Sourabh and Ritik are first cousins, Sourabh and Ritik belong to the third generation as second cousins. Thus, they are cousins.

Explanation

The series follows a pattern where each term is multiplied by a decreasing sequence of integers to obtain the subsequent term.

1 × 7 = 7 7 × 6 = 42 42 × 5 = 210 210 × 4 = 840

Following this sequence, the next multiplier must be 3. Thus, the missing term is: 840 × 3 = 2520

Explanation

The first statement establishes that children play in the playground, which is an outdoor environment. The second statement explains that this activity provides them with a different approach to problem-solving and decision-making. Since developing problem-solving and decision-making skills is a fundamental part of a child's cognitive and personal growth, it directly supports the idea that playing outdoors is necessary for their overall development. Thus, conclusion I logically follows from the given statements.

Explanation

By translating the given statements into inequalities, we have: C > E E > B This gives the relation C > E > B. Since C is the second richest after A, we know A is the richest, which gives A > C. Combining all the relationships, we get the complete order from richest to poorest as: A > C > E > B Thus, B has the least amount of money.

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 two letters of each word, Ma comes before Mo. Therefore, Monopoly (i) starts with Mo and must be placed last in the sequence.

For the remaining three words starting with Man: Manifesto (ii) and Manifold (iii) have the fourth letter as i, while Mankind (iv) has the fourth letter as k. Since i comes before k in the alphabet, Mankind (iv) comes after Manifesto (ii) and Manifold (iii).

Now comparing Manifesto (ii) and Manifold (iii), both share the letters M-a-n-i-f. The sixth letter in Manifesto is e and in Manifold is o. Since e comes before o, Manifesto (ii) comes before Manifold (iii).

Combining these steps, the correct alphabetical sequence is Manifesto (ii), Manifold (iii), Mankind (iv), and Monopoly (i).

Explanation

The coding follows a specific pattern where the letters of the word are reversed, and then a shift is applied. For the first letter of the original word (which becomes the last letter of the reversed word), the position is shifted by +1. For all other letters, the position is shifted by -1.

Applying this to HISTORY: Reversed order: Y R O T S I H Shifting the letters: Y - 1 = X R - 1 = Q O - 1 = N T - 1 = S S - 1 = R I - 1 = H H + 1 = I This yields the code XQNSRHI.

Applying the same pattern to ETHICS: Reversed order: S C I H T E Shifting the letters: S - 1 = R C - 1 = B I - 1 = H H - 1 = G T - 1 = S E + 1 = F This yields the code RBHGSF.

Explanation

The logic of this grid pattern lies in the sum of the numbers in each of the three columns. Calculating the sum of the elements in the first two columns reveals a constant total:

First column sum: 6 + 7 + 3 = 16

Second column sum: 10 + 2 + 4 = 16

Applying this constant sum of 16 to the third column, the missing value can be calculated as follows: 9 + 1 + ? = 16 10 + ? = 16 ? = 16 - 10 ? = 6

Explanation

Substituting the given letters with their respective mathematical operators, where L represents ÷, S represents ×, V represents -, and M represents +:

96 ÷ 8 × 4 - 16 + 9

Applying the BODMAS rule:

First, perform the division: 96 ÷ 8 = 12

Next, perform the multiplication: 12 × 4 = 48

Finally, perform the addition and subtraction from left to right: 48 - 16 + 9 = 32 + 9 = 41

Explanation

The given letter series can be divided into three repeating groups of four letters: c_e_ / cd_f / _d_f

The pattern followed is the repetition of the four-letter block cdef: In the first group (c_e_), filling d and f completes the block as cdef. In the second group (cd_f), filling e completes the block as cdef. In the third group (_d_f), filling c and e completes the block as cdef.

Sequentially placing the missing letters d, f, e, c, and e in the gaps completes the series to cdef cdef cdef.

Explanation

The relationship between the first pair of words is based on antonyms, as coward is the opposite of brave. Following the same analogy, the word related to culprit must be its antonym. A culprit is someone who is guilty of a crime or misdeed, and the direct opposite of being guilty or a culprit is being innocent.

Explanation

The relationship between the first pair of words is based on opposite letters in the English alphabet, where the sum of the numerical positions of the original letter and its corresponding opposite letter is always 27.

In the word LOGIC: L with position 12 corresponds to O with position 15, since 12 + 15 = 27 O with position 15 corresponds to L with position 12, since 15 + 12 = 27 G with position 7 corresponds to T with position 20, since 7 + 20 = 27 I with position 9 corresponds to R with position 18, since 9 + 18 = 27 C with position 3 corresponds to X with position 24, since 3 + 24 = 27 This results in OLTRX.

Applying this same alphabetical opposite rule to SOUND: S with position 19 corresponds to H with position 8, since 19 + 8 = 27 O with position 15 corresponds to L with position 12, since 15 + 12 = 27 U with position 21 corresponds to F with position 6, since 21 + 6 = 27 N with position 14 corresponds to M with position 13, since 14 + 13 = 27 D with position 4 corresponds to W with position 23, since 4 + 23 = 27 This results in HLFMW.
