Explanation

The relationship in the given analogy is between a professional and their primary working tool. A farmer uses a plough as the essential tool to till the land and perform agricultural work. Similarly, a painter uses a brush as the essential tool to apply paint and create artwork.

Explanation

To find the relation, we represent each letter by its alphabetical position: A = 1, B = 2, C = 3, D = 4, E = 5, F = 6, G = 7, H = 8, I = 9, J = 10, ..., Y = 25, Z = 26.

Analyzing the pairs: In DB, D = 4 and B = 2. The relationship is: D = B² (4 = 2²). In IC, I = 9 and C = 3. The relationship is: I = C² (9 = 3²). In YE, Y = 25 and E = 5. The relationship is: Y = E² (25 = 5²).

The second letters of the consecutive pairs form the sequence: B (2) → (+1) → C (3) → (+2) → E (5)

Following the alternating pattern of adding 1 and 2, the next second letter is: E (5) → (+1) → F (6)

Using the established square relationship, the first letter of the next pair is: 6² = 36

Since there are only 26 letters in the English alphabet, we wrap around: 36 − 26 = 10, which corresponds to the letter J.

Combining the letters J and F gives JF.

Explanation

The relationship between the first two groups of letters is established by shifting each letter forward by 6 positions in the alphabetical order.

Converting the letters of AEG to their alphabetical positions: A = 1, E = 5, G = 7

Adding 6 to each position: 1 + 6 = 7 (G) 5 + 6 = 11 (K) 7 + 6 = 13 (M)

Applying this same rule to MQS, where the alphabetical positions are M = 13, Q = 17, S = 19: 13 + 6 = 19 (S) 17 + 6 = 23 (W) 19 + 6 = 25 (Y)

This results in SWY.

Explanation

The relationship between the first pair of numbers is based on the reversal of their digits. When the digits of the number 17 are written in reverse order, it becomes 71. Applying the same logic to the second pair, when the digits of the number 35 are reversed, it becomes 53.

Explanation

Magnetic field represents a physical quantity, unlike the other options which are standard SI units of measurement.

Explanation

Only the letters in CDE are consecutive alphabets in the English alphabetical order. In all other options, the letters are non-consecutive.

Explanation

The number 4099 is not a perfect cube, whereas all the other numbers are perfect cubes of integers: 13³ = 2197 14³ = 2744 15³ = 3375

Since 16³ is 4096, 4099 is not a perfect cube, making it the odd number.

Explanation

The sum of the digits of 576 is 18 (5 + 7 + 6 = 18), whereas the sum of the digits of the other numbers is 20 (7 + 9 + 4 = 20, 6 + 6 + 8 = 20, 9 + 9 + 2 = 20). Alternatively, 576 is a perfect square (24² = 576), unlike the other numbers in the set.

Explanation

The series represents the civilian awards of India arranged in ascending order of their hierarchy. Padma Shri is the fourth-highest civilian award, Padma Bhushan is the third-highest, and Padma Vibhushan is the second-highest. The sequence naturally culminates with Bharat Ratna, which is the highest civilian award of the Republic of India, awarded for the highest degree of national service.

Explanation

The series progresses by adding 3 to the alphabetical position of each letter from one term to the next.

For the first letter, the sequence is C, F, I, which corresponds to the positions 3, 6, and 9. Adding 3 to 9 gives 12, which represents L.

For the second letter, the sequence is A, D, G, corresponding to the positions 1, 4, and 7. Adding 3 to 7 gives 10, which represents J.

For the third letter, the sequence is E, H, K, corresponding to the positions 5, 8, and 11. Adding 3 to 11 gives 14, which represents N.

This sequence of transformations yields the term L J N.

Explanation

The series consists of two independent letter patterns.

For the first letter of each term, the letters advance by two positions in alphabetical order: A + 2 = C C + 2 = E E + 2 = G

For the second letter of each term, the letters go backward by two positions in alphabetical order: Y - 2 = W W - 2 = U U - 2 = S

Combining both patterns, the next term in the series is GS.

Explanation

The terms of the series follow the mathematical pattern where each number is obtained by adding 1 to the square of terms that are in an arithmetic progression with a common difference of 3:

122 = 11² + 1 197 = 14² + 1 290 = 17² + 1

The sequence of the base numbers is 11, 14, 17. The next number in this arithmetic sequence is: 17 + 3 = 20

Applying the same pattern to find the missing term: 20² + 1 = 400 + 1 = 401

Explanation

The first statement highlights that job creation is not keeping pace with economic growth, meaning the creation of new employment opportunities is slow. The second statement mentions that over 20 million young Indians enter the workforce annually, which is a direct consequence of population growth.

Conclusion I directly follows because the addition of 20 million individuals to the workforce each year represents a population-driven increase in job seekers that far outpaces the slow rate of job creation.

Conclusion II also follows because the slow rate of job creation translates to a smaller supply of available jobs, which represents the supply basket. At the same time, the massive annual influx of 20 million young workforce entrants represents an extremely high demand for jobs, which represents the demand basket. Therefore, the supply of jobs is indeed less than the demand for them.

Explanation

Based on the given conditions, the exact sitting arrangement can be determined step-by-step. Since Shalini is to the immediate right of Neha, they must sit as Neha then Shalini. Rekha is sitting between Shalini and Neetu, which expands the arrangement to Neha then Shalini then Rekha then Neetu. Finally, Pooja sits to the immediate right of Neetu, completing the five-girl sequence from left to right as Neha, Shalini, Rekha, Neetu, and Pooja. In this arrangement, Rekha sits in the third position, which is exactly in the middle of the row.

Explanation

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

All four words begin with the letter n.

Comparing their second letters, nature has a, nest and news have e, and numeric has u. Since a comes first in the alphabet, nature (i) is placed first.

Next, comparing the two words starting with ne, which are nest and news, we look at their third letters. The letter s in nest comes before w in news. This places nest (ii) before news (iv).

Finally, numeric (iii) has u as its second letter, which comes after a and e in the alphabet, making it the last word in the sequence.

The alphabetical arrangement of the words is i, ii, iv, iii.

Explanation

The coding pattern involves writing the letters of the word in reverse order.

Applying this to the word TRAIN: T-R-A-I-N is reversed to N-I-A-R-T.

Applying this to the word SCOOTER: S-C-O-O-T-E-R is reversed to R-E-T-O-O-C-S.

Explanation

Substituting the mathematical operators as specified: × becomes ÷ becomes ×

• becomes - ÷ becomes +

The given expression is: 38 × 2 - 6 + 19 ÷ 35

Substituting the operators gives: 38 ÷ 2 × 6 - 19 + 35

Applying the BODMAS rule: First perform the division: 38 ÷ 2 = 19

Next perform the multiplication: 19 × 6 = 114

Then perform the addition and subtraction: 114 - 19 + 35 = 95 + 35 = 130

Explanation

By interchanging the signs x and + and the numbers 8 and 2 in the given equation 8 x 9 + 2 = 74, we get:

2 + 9 x 8 = 74

Applying the order of operations, we first perform the multiplication:

9 x 8 = 72

Then we perform the addition:

2 + 72 = 74

This results in 74 = 74, which makes the equation correct.

Explanation

The letter series follows an alternating pattern of 4-letter groups: abbc and accb.

When we insert the letters bccbb from Option A sequentially into the gaps, the completed series becomes:

abbcaccbabb

This can be divided into: First group: abbc Second group: accb Third group: abb (the first three letters of the next abbc group)

Therefore, the set of letters bccbb completes the series logically.

Explanation

Initially, the man is facing West. An anti-clockwise turn of 90 degrees from West aligns his direction to South. After moving 10 meters straight facing South, he performs another 90-degree anti-clockwise turn. A 90-degree anti-clockwise turn from South points directly to East.

Explanation

In matrix-based coding, a letter is represented first by its row number and then by its column number. To find the representation for the word ALIKE, each letter can be verified as follows:

For the letter A, looking at Matrix-II, Row 7 and Column 8 intersect at A, giving the code 78.

For the letter L, looking at Matrix-I, Row 3 and Column 2 intersect at L, giving the code 32.

For the letter I, looking at Matrix-II, Row 7 and Column 7 intersect at I, giving the code 77.

For the letter K, looking at Matrix-I, Row 1 and Column 2 intersect at K, giving the code 12.

For the letter E, looking at Matrix-II, Row 8 and Column 6 intersect at E, giving the code 86.

Combining these codes in sequence yields the correct set: 78, 32, 77, 12, 86.

Explanation

Vidit's grandmother is the mother of Vidit's father. For this grandmother to be the mother-in-law of the lady in the photograph, the lady must be married to the grandmother's son, who is Vidit's father. Consequently, the lady in the photograph is the mother of Vidit.

Explanation

This analogy is based on the relationship between a professional and their primary workplace. A scientist conducts scientific research and experiments in a laboratory. In the same way, an astronomer carries out observations and studies of celestial phenomena from an observatory.

Explanation

The relationship between the first pair of letter clusters is established by adding 1 to the alphabetical position of each letter:

C + 1 = D G + 1 = H K + 1 = L

Applying the same logic to the next cluster:

U + 1 = V Y + 1 = Z C + 1 = D

Therefore, UYC is related to VZD.

Explanation

In the first analogy pair, BCD : DEG, the last letter of the first term (D) becomes the first letter of the second term (DEG).

Applying the same logic to the second pair, FIJ : ?, the last letter of the first term (J) must be the first letter of the succeeding term. Among the options, JLN is the only letter group that begins with the letter J.

Explanation

The pattern in the given analogy is based on the products of consecutive integers:

56 = 7 × 8 72 = 8 × 9 90 = 9 × 10

Following this sequential pattern, the missing number is:

10 × 11 = 110

Alternatively, the relationship can be expressed using the formula n² + n for consecutive integers starting from n = 7:

7² + 7 = 56 8² + 8 = 72 9² + 9 = 90 10² + 10 = 110

Explanation

Polygon is a general classification representing any closed, flat geometric shape with straight sides. Square, rectangle, and rhombus are specific types of polygons with exactly four sides (quadrilaterals). This makes polygon the odd one out as it represents a broad category rather than a specific geometric figure.

Explanation

In the letter group MNO, the letters are consecutive in the alphabetical order with a difference of +1 between successive positions (13 → 14 → 15). All other groups have a difference of +2 between consecutive letters.

Explanation

The sum of the digits of 264 is 12 (2 + 6 + 4 = 12), which is not divisible by 9, whereas the sum of the digits for each of the other numbers is 9, making them divisible by 9. Additionally, 264 is the only even number in the given set, while the other numbers are all odd.

Explanation

The common rule governing these numbers is that the sum of the first two digits equals the third digit. For instance, adding the first digit and the second digit results in the third digit. In the number 346, the sum of the first two digits is 3 + 4 = 7, which is not equal to the third digit 6. This makes 346 the odd one out as it is the only number that does not satisfy this arithmetic relation.

Explanation

The given terms represent the consecutive colors of a rainbow in sequential order. The standard order of colors in a rainbow is represented by the acronym ROYGBIV, which stands for Red, Orange, Yellow, Green, Blue, Indigo, and Violet. Following this sequence from left to right, the color that immediately succeeds Yellow is Green.

Explanation

The relationship in the first pair is that Nephrology is the branch of medical science concerned with the study and treatment of kidneys. Applying the same relationship to the second pair, Ichthyology is the branch of zoology dedicated to the study of fish.

Explanation

The given series follows a distinct pattern for the first and second letters of each term.

For the first letter of each term: C → E → G → ? The alphabetical positions are 3, 5, and 7. This is an increasing progression with a difference of +2. The position of the next letter is 7 + 2 = 9, which corresponds to the letter I.

For the second letter of each term: M → K → I → ? The alphabetical positions are 13, 11, and 9. This is a decreasing progression with a difference of -2. The position of the next letter is 9 - 2 = 7, which corresponds to the letter G.

Combining both parts yields the next term in the series, which is IG.

Explanation

Each letter in the terms increases by 8 positions in the alphabetical order.

For the first letters, F is the 6th letter, N is the 14th letter, and V is the 22nd letter. Adding 8 to 22 gives 30, which corresponds to D (the 4th letter) after wrapping around the 26-letter alphabet.

For the second letters, G is the 7th letter, O is the 15th letter, and W is the 23rd letter. Adding 8 to 23 gives 31, which corresponds to E (the 5th letter) after wrapping around the alphabet.

For the third letters, H is the 8th letter, P is the 16th letter, and X is the 24th letter. Adding 8 to 24 gives 32, which corresponds to F (the 6th letter) after wrapping around the alphabet.

Explanation

The terms of the given series are perfect squares of consecutive numbers in a Fibonacci sequence.

4 = 2² 9 = 3² 25 = 5² 64 = 8² 169 = 13²

The base values of the squares are 2, 3, 5, 8, and 13. This sequence of bases is a Fibonacci series where each term is the sum of the preceding two terms:

2 + 3 = 5 3 + 5 = 8 5 + 8 = 13

Following this pattern, the next base value in the sequence is:

8 + 13 = 21

Squaring this base value gives:

21² = 441

Explanation

In statement-conclusion evaluation, conclusions must be logically deduced solely from the facts stated in the premises. The given statements only describe the successful testing of the Smart Anti Airfield Weapon by the DRDO from an Indian Air Force aircraft, alongside the weapon's specifications as a lightweight, high-precision guided bomb.

Neither statement mentions Dr. S. Christopher congratulating the teams nor identifies the specific testing agency as the IAF's Aircraft and System Testing Establishment. Since both conclusions contain external factual information that cannot be inferred from the premises, neither conclusion I nor conclusion II logically follows.

Explanation

Sanjeev scored the highest marks, which secures him the 1st rank. This leaves the remaining four ranks to be decided among Sameer, Arpit, Rahul, and Nirbhay.

According to the given information, Rahul scored more than Nirbhay (Rahul > Nirbhay), while both Sameer and Arpit scored more than Rahul (Sameer > Rahul and Arpit > Rahul).

Since Nirbhay scored lower than Rahul, who in turn scored lower than everyone else, Nirbhay must have the lowest score, placing him at the 5th rank. Since both Sameer and Arpit scored higher than Rahul, they must occupy the 2nd and 3rd ranks in some order. Consequently, Rahul is positioned directly below Sameer and Arpit but above Nirbhay, which uniquely places him at the 4th rank.

Explanation

To arrange the words in dictionary order, we compare them letter by letter from left to right. All four words begin with the common prefix fore. Therefore, we compare the fifth letter of each word:

In Forehead (i), the fifth letter is h. In Forensic (ii), the fifth letter is n. In Forest (iii), the fifth letter is s. In Foremost (iv), the fifth letter is m.

Arranging these fifth letters in alphabetical order gives h, m, n, s, which corresponds to the sequence i, iv, ii, iii.

Explanation

The coding pattern splits the word into parts, reverses each part, shifts each letter to its next alphabetical letter (+1), and then reverses the sequence of the parts.

For the 6-letter word SELDOM: It is divided into two halves: SEL and DOM. Reversing them gives LES and MOD. Shifting each letter by +1 gives MFT and NPE. Placing the coded second half before the coded first half results in NPEMFT.

For the 9-letter word SACRIFICE: It is divided into three parts: the first four letters (SACR), the middle letter (I), and the last four letters (FICE). Reversing each part gives RCAS, I, and ECIF. Shifting each letter by +1 gives SDBT, J, and FDJG. Placing the coded parts in reverse order (second half, middle letter, first half) yields FDJGJSDBT.

Explanation

The logic of the grid is based on columns, where the square of the difference between the first and second row elements gives the third row element:

(Row 1 - Row 2)² = Row 3

In the first column: (17 - 8)² = 9² = 81

In the third column: (16 - 11)² = 5² = 25

Following this rule for the second column: (24 - ?)² = 100

Taking the square root on both sides: 24 - ? = 10 ? = 24 - 10 = 14

Explanation

To find the value of the given expression, replace the letters with their respective mathematical operations as specified: L represents ÷ S represents × V represents - M represents +

Substituting these into the given expression: 343 ÷ 7 × 6 - 94 + 11

Applying the BODMAS rule (Brackets, Orders, Division, Multiplication, Addition, Subtraction):

First, perform the division: 343 ÷ 7 = 49

Next, perform the multiplication: 49 × 6 = 294

Now, solve the remaining addition and subtraction from left to right: 294 - 94 + 11 = 200 + 11 = 211

Explanation

When we sequentially place the letters from option B (qqrpq) into the gaps of the series r_pr_p_q_r_p, we get the repeating pattern "rqp rqp rqp rqp".

Explanation

The relationship is established by first reversing the letters of the word and then shifting each letter in the reversed sequence by a specific numerical pattern.

Reversing the word AGREE gives EERGA. Applying the shift pattern to EERGA: The first letter E is shifted by +1 to get F. The second letter E is shifted by +2 to get G. The third letter R is shifted by -2 to get P. The fourth letter G is shifted by +2 to get I. The fifth letter A is shifted by +1 to get B. This results in FGPIB.

Applying the same logic, reversing the word RULES gives SELUR. Shifting the letters of SELUR using the same pattern: The first letter S is shifted by +1 to get T. The second letter E is shifted by +2 to get G. The third letter L is shifted by -2 to get J. The fourth letter U is shifted by +2 to get W. The fifth letter R is shifted by +1 to get S. This results in TGJWS.

Explanation

Let the initial position of the man be at the origin (0, 0).

Moving 24 metres South brings him to the coordinate (0, -24).

Turning 90 degrees anticlockwise changes his direction to East. Moving 7 metres East brings him to (7, -24).

Taking a right turn from East changes his direction to South. Moving 3 metres South brings him to (7, -27).

Finally, moving 3 metres North brings him back to (7, -24).

The straight-line distance d between the initial position (0, 0) and the final position (7, -24) is calculated using the Pythagorean theorem:

d = √(7² + 24²) d = √(49 + 576) d = √625 d = 25 m

Explanation

Each letter of the word MODEST is represented by a set of two digits, where the first digit denotes the row number and the second digit denotes the column number.

Using this row-by-column rule, the coordinates for the letters in the word MODEST map perfectly to the sequence in option D:

M is represented by 67, which corresponds to row 6 and column 7 in Matrix-II. O is represented by 13, which corresponds to row 1 and column 3 in Matrix-I. D is represented by 86, which corresponds to row 8 and column 6 in Matrix-II. E is represented by 34, which corresponds to row 3 and column 4 in Matrix-I. S is represented by 77, which corresponds to row 7 and column 7 in Matrix-II. T is represented by 33, which corresponds to row 3 and column 3 in Matrix-I.

Explanation

Nisha's father's brother-in-law is the brother of Nisha's mother, which makes him Nisha's maternal uncle.

Since this maternal uncle is also the brother of Neha, Neha must be the sister of Nisha's mother, which means Neha is Nisha's maternal aunt.

Consequently, Nisha is the niece of Neha.

Explanation

The pattern is based on swapping the letters of each adjacent pair in the given word.

In MUMBAI: MU becomes UM MB becomes BM AI becomes IA This gives UMBMIA.

Applying the same pattern to GURUGRAM: GU becomes UG RU becomes UR GR becomes RG AM becomes MA This gives UGURRGMA.

Explanation

The relationship between the first and the second number is defined by dividing the first number by 2 and then adding 1 to the result.

Applying this rule to the first pair: 30 ÷ 2 + 1 = 15 + 1 = 16

Applying the same rule to the second pair: 24 ÷ 2 + 1 = 12 + 1 = 13

Explanation

The lion is a wild animal that belongs to the Panthera genus and lives in natural habitats like grasslands and savannahs. Unlike the others, which are domesticated animals commonly kept by humans as companions or livestock, the lion is a wild predator.

Explanation

The correct option contains two vowels (U and A) and no consonants. All other options consist of exactly one vowel and one consonant, making this option the odd one out.
