Explanation

The given series is based on mountain peaks arranged in ascending order of their heights above sea level.

Nanga Parbat has an elevation of 8,126 meters. Kanchenjunga has an elevation of 8,586 meters. Mount Godwin-Austen, also known as K2, has an elevation of 8,611 meters.

Following this increasing order of height, the next term in the series must have a greater elevation. Mount Everest is the highest mountain peak in the world with an elevation of 8,848 meters, which logically completes this ascending sequence.

Explanation

The series follows a pattern based on the alphabetical positions of the letters, where each term consists of three consecutive letters.

By analyzing the first letter of each term: The first letter of the first term is G (7th position). The first letter of the third term is T (20th position). The first letter of the fourth term is B (2nd position, or 28th in a continuous alphabetical cycle).

The difference between the first letters of the third and fourth terms is 28 - 20 = 8. Following an increasing difference pattern of +6, +7, and +8: The first letter of the missing term is 7 + 6 = 13, which is M. To verify: 13 + 7 = 20, which is T.

Since each term consists of three consecutive letters starting from its first letter, the missing term starting with M is MNO.

Explanation

The differences between the consecutive corresponding letters in the series increase progressively by one, based on their alphabetical positions (where A = 1, B = 2, ..., Z = 26, wrapping around after 26).

For the first letter of each term: First letter of the missing term + 4 = Y (25) Y (25) + 5 = D (4, since 25 + 5 = 30, which corresponds to 4 after wrapping around Z) D (4) + 6 = J (10)

This gives the first letter of the missing term as 25 - 4 = 21, which is U.

For the second letter of each term: Second letter of the missing term + 4 = Z (26) Z (26) + 5 = E (5, since 26 + 5 = 31, which corresponds to 5 after wrapping around Z) E (5) + 6 = K (11)

This gives the second letter of the missing term as 26 - 4 = 22, which is V.

Combining these letters yields the term UV.

Explanation

The difference between consecutive terms in the series forms a sequence of consecutive perfect squares:

3 - 2 = 1 = 1² 7 - 3 = 4 = 2² 16 - 7 = 9 = 3²

Following this pattern, the next difference must be 4² = 16. Adding this difference to the last term gives:

16 + 16 = 32

Explanation

The given sequence is an arithmetic progression where each subsequent term is obtained by adding a constant difference of 1.5 to the preceding term.

The differences between the consecutive terms are: 2 - 0.5 = 1.5 3.5 - 2 = 1.5

Applying this common difference of 1.5 to find the missing term: 3.5 + 1.5 = 5

We can verify this pattern with the final term of the series: 5 + 1.5 = 6.5

Explanation

We can determine the running speed order of the five friends using inequalities based on the given statements.

First, Janvi runs faster than Ritika but slower than Priya, which gives the relationship: Priya > Janvi > Ritika.

Second, Riya runs faster than Priya, which extends the relationship to: Riya > Priya > Janvi > Ritika.

Third, Mohan is the slowest runner, which completes the speed sequence as: Riya > Priya > Janvi > Ritika > Mohan.

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 all words, we group them into words starting with Be (Beguile and Begun) and words starting with Bi (Bigot and Bigamy). Since e comes before i, the Be words will appear first.

Among the Be words, Beguile (i) and Begun (iii) share the first four letters B-e-g-u. Comparing the fifth letters, i in Beguile comes before n in Begun, which places Beguile (i) before Begun (iii).

Among the Bi words, Bigot (ii) and Bigamy (iv) share the first three letters B-i-g. Comparing the fourth letters, a in Bigamy comes before o in Bigot, which places Bigamy (iv) before Bigot (ii).

Combining these two groups gives the correct alphabetical sequence: i, iii, iv, ii.

Explanation

The code for each letter is derived from the given words:

In RAINBOW, R is coded as 1, A is 9, I is 8, N is 7, B is 6, O is 4, and W is 5.

In SNAP, S is coded as 3, N is 7, A is 9, and P is 0.

By mapping these specific letter codes to the word PIANO: P corresponds to 0 I corresponds to 8 A corresponds to 9 N corresponds to 7 O corresponds to 4

This yields the sequence 08974, which corresponds to 8974.

Explanation

The second statement states that some trees are hens. In syllogisms, a particular affirmative proposition of the form "Some A are B" can be logically converted into "Some B are A". Applying this conversion rule to the statement "Some trees are hens" directly yields "Some hens are trees". Therefore, Conclusion II logically follows from the given statements.

Explanation

By substituting the operations as specified: B denotes minus (-) C denotes plus (+) D denotes division (÷) A denotes multiplication (×)

The given expression is: 8 - 31 + 49 ÷ 7 × 16

Applying the BODMAS rule:

First, perform the division: 49 ÷ 7 = 7 The expression becomes: 8 - 31 + 7 × 16

Next, perform the multiplication: 7 × 16 = 112 The expression becomes: 8 - 31 + 112

Finally, perform the addition and subtraction from left to right: 8 - 31 + 112 = -23 + 112 = 89

Explanation

Substituting the letters from option C (y, y, y, z) sequentially into the gaps of the given series x_zz_xx_z_yx yields:

x y z z y x x y z z y x

This completed sequence reveals a highly consistent, repeating pattern. The series of 12 letters can be divided into two identical 6-letter groups:

x y z z y x | x y z z y x

This can also be understood as a series of alternating 3-letter segments, where each segment is followed by its reverse:

x y z | z y x | x y z | z y x

Explanation

Let the starting point be designated as (0, 0) on a coordinate plane, where the positive x-axis represents East and the positive y-axis represents North.

Ram first travels 5 km East, which brings him to the coordinates (5, 0).

He then turns left, which is North, and travels 10 km, reaching the coordinates (5, 10).

Next, he turns right, facing East, and travels 5 km, placing him at (10, 10).

Finally, he turns right, facing South, and travels 10 km, ending at (10, 0).

The straight-line distance from the starting point (0, 0) to the final position (10, 0) is 10 - 0 = 10 km.

Explanation

America is the odd one out because it is located in the Western Hemisphere (North America), whereas India, Bangladesh, and Pakistan are all neighbouring countries located in the South Asian region of the Asian continent.

Explanation

Julie is the mother of Zeeshan and Yana. Since Zeba is the sister of Zeeshan's mother, Zeba is Julie's sister. Because Yana is Julie's daughter, she is the niece of Julie's sister, Zeba.

Explanation

The given series represents the chronological stages in the growth and development lifecycle of a plant. The cycle begins with a seed, which germinates and grows into a sapling. The sapling matures into a full plant, which then produces flowers. Following pollination and fertilization, the flower develops into a fruit containing seeds, completing the sequential development.

Explanation

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

First, comparing the first three letters of each word, Aperture begins with A-p-e, while Application, Appliance, and Appeal begin with A-p-p. Since e comes before p in the alphabet, Aperture (i) is the first word in the sequence.

Next, comparing the remaining words, Appeal has e as its fourth letter, whereas Application and Appliance have l as their fourth letter. Since e comes before l, Appeal (iv) comes next.

Finally, comparing Application and Appliance, both share the first five letters A-p-p-l-i. Looking at their sixth letters, Appliance has a while Application has c. Since a comes before c, Appliance (iii) precedes Application (ii).

This gives the complete alphabetical sequence as i, iv, iii, ii.

Explanation

Among the five individuals A, B, C, D, and E, A has the second highest weight. Since E weighs more than A, and there is only one position heavier than the second heaviest, E must be the heaviest person.

Explanation

Sound is a mechanical wave, which means it requires a physical medium to propagate. In contrast, light is an electromagnetic wave, which is self-propagating and does not require a physical medium to travel, allowing it to propagate through a vacuum.

Explanation

The relationship between the letter pairs is established by adding specific positional values to each letter.

For the first pair, TR to VX: T (20th letter) + 2 = V (22nd letter) R (18th letter) + 6 = X (24th letter)

Applying the same pattern of +2 and +6 to MK: M (13th letter) + 2 = O (15th letter) K (11th letter) + 6 = Q (17th letter)

Explanation

The relationship is based on the sum of the numerical positions of the letters in the English alphabetical order.

For the first pair, ZY and CD: The position of Z is 26 and C is 3. Their sum is 26 + 3 = 29. The position of Y is 25 and D is 4. Their sum is 25 + 4 = 29.

Applying the same logic to the second pair, SR and the missing term: The position of S is 19. To get a sum of 29, the corresponding letter must be 29 - 19 = 10, which is J. The position of R is 18. To get a sum of 29, the corresponding letter must be 29 - 18 = 11, which is K.

This gives the letters JK.

Explanation

The given analogy follows the pattern of cubes of consecutive natural numbers, representing the relation n³ : (n + 1)³.

For the first pair: 8 = 2³ 27 = (2 + 1)³ = 3³

For the second pair: 64 = 4³ The next term in the sequence is (4 + 1)³ = 5³ = 125.

Explanation

Radius is a geometric measurement associated with a circle, representing the constant distance from the center of the circle to its boundary. In contrast, the other three terms define the specific sides of a right-angled triangle. Since radius is the only term related to circular geometry rather than triangular geometry, it is the odd one out.

Explanation

The letter pair WZ has a positional difference of 3 between its letters, with W being the 23rd letter and Z being the 26th letter of the English alphabet, whereas all other pairs have a consistent gap of 4 letters between them.

Explanation

In 246, the middle digit is the average of the first and the last digits: (2 + 6) ÷ 2 = 4

Additionally, all of its individual digits are even numbers (2, 4, and 6), which form a consecutive sequence of even numbers.

Explanation

The number 173 is a prime number, whereas all the other numbers are composite numbers. Furthermore, the sum of the digits of 173 is 11, which is not divisible by 3, while the sum of the digits of each of the other numbers is a multiple of 3, making them divisible by 3.

Explanation

The given series represents the standard units of computer data storage ordered in ascending order of their capacity. A bit is the basic unit of information, followed by a byte, which consists of 8 bits. The subsequent units increase sequentially by a factor of 1024, progressing from Kilobyte to Megabyte. The unit that immediately follows Megabyte in this ascending sequence is the Gigabyte.

Explanation

The first letters of the terms follow a pattern of adding 3 to their alphabetical positions: B (2) + 3 = E (5) E (5) + 3 = H (8) H (8) + 3 = K (11)

Similarly, the second letters of the terms also follow a pattern of adding 3 to their alphabetical positions: D (4) + 3 = G (7) G (7) + 3 = J (10) J (10) + 3 = M (13)

Combining the two, the next term in the series is KM.

Explanation

The series follows a specific mathematical progression based on the alphabetical positions of each letter.

For the first letters of each term: W, S, O The positions of these letters in alphabetical order are 23, 19, and 15 respectively, decreasing by 4 at each step. 23 - 4 = 19 (S) 19 - 4 = 15 (O) 15 - 4 = 11, which corresponds to K.

For the second letters of each term: D, H, L The positions of these letters in alphabetical order are 4, 8, and 12 respectively, increasing by 4 at each step. 4 + 4 = 8 (H) 8 + 4 = 12 (L) 12 + 4 = 16, which corresponds to P.

Combining these two sequences gives the next term as KP.

Explanation

The series follows a pattern where the difference between consecutive terms increases by consecutive odd numbers.

25 - 18 = 7 34 - 25 = 9 45 - 34 = 11

Following this pattern, the difference between the missing term and 45 must be the next odd number, which is 13. Adding 13 to the last term gives:

45 + 13 = 58

Explanation

The given series represents consecutive powers of the number 7.

The terms of the series are calculated as follows:

First term: 7¹ = 7

Second term: 7² = 49

Third term: 7³ = 343

Following this pattern, the next term in the series is:

Fourth term: 7⁴ = 2401

Explanation

Using the average formula, the sum of values is equal to the product of the average and the number of observations.

When Ram's uncle is included, the total number of people becomes 3, and their average age is 40.

Sum of ages of all 3 individuals = Average × Number of people = 40 × 3 = 120

The sum of the ages of Ram and his son is given as 48.

Age of Ram's uncle = Sum of ages of all 3 individuals - Sum of ages of Ram and his son Age of Ram's uncle = 120 - 48 = 72

Explanation

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

All four words start with the prefix Ac.

Comparing Accord (ii) and Accuse (i), both start with Acc. The fourth letter of Accord is o and the fourth letter of Accuse is u. Since o comes before u in the alphabet, Accord (ii) comes before Accuse (i).

Comparing Acquire (iv) and Acquisite (iii), both start with Acqui. The sixth letter of Acquire is r and the sixth letter of Acquisite is s. Since r comes before s in the alphabet, Acquire (iv) comes before Acquisite (iii).

Since c comes before q in the alphabet, the words starting with Acc come before those starting with Acq.

Combining these comparisons gives the dictionary order: Accord (ii), Accuse (i), Acquire (iv), Acquisite (iii).

Explanation

The coding follows a two-step pattern of reversal and swapping of specific letter positions.

First, reverse the order of the letters in the word. Second, swap the positions of the third and fourth letters in this reversed sequence.

Applying this to STYLE: Reversing the letters of STYLE yields E L Y T S. Swapping the third letter (Y) and the fourth letter (T) yields E L T Y S.

Applying the same logic to FRUIT: Reversing the letters of FRUIT yields T I U R F. Swapping the third letter (U) and the fourth letter (R) yields T I R U F.

Explanation

The correct answer is identified by finding the odd number based on a specific mathematical relation. In the other numbers, the product of the first two digits is equal to the number formed by the last two digits, such as 4 × 4 = 16, 8 × 4 = 32, and 4 × 5 = 20. The number 4260 is the odd one out because it violates this rule, as the product of its first two digits is 4 × 2 = 8, whereas its last two digits form the number 60.

Explanation

Substituting the given letters with their corresponding mathematical operators: V denotes subtraction (-) M denotes addition (+) L denotes division (÷) S denotes multiplication (×)

The expression 5 V 9 M 63 L 9 S 7 is written as: 5 - 9 + 63 ÷ 9 × 7

Applying the BODMAS rule, perform division first: 63 ÷ 9 = 7

Next, perform multiplication: 7 × 7 = 49

Finally, perform addition and subtraction from left to right: 5 - 9 + 49 = 45

Explanation

The letter series follows a pattern where the group of letters x, y, and z increases in frequency in each subsequent block:

First block: x y z (each letter appears once) Second block: x x y y z z (each letter appears twice) Third block: x x x y y y z z z (each letter appears thrice)

This results in the complete series: xyzxxyyzzxxxyyyzzz.

Comparing this complete series with the original sequence x_zx_y_z_x_xyy_zzz, we can identify the letters needed to fill the gaps sequentially:

The first gap is filled with y. The second gap is filled with x. The third gap is filled with y. The fourth gap is filled with z. The fifth gap is filled with x. The sixth gap is filled with y.

Placing these letters (y, x, y, z, x, y) in the blanks completes the series.

Explanation

The boy is initially moving towards the west. When he makes a right turn, his direction changes by ninety degrees clockwise, which points towards the north. From north, making a left turn changes his direction by ninety degrees counterclockwise, which points back towards the west. Therefore, the boy is now facing the west.

Explanation

The given series represents the member countries of the BRICS international organization in the sequence of its acronym. The acronym is formed by the first letters of Brazil, Russia, India, China, and South Africa. This makes India the missing term that completes the series.

Explanation

Rajesh is the father-in-law of Neha, which means Neha is married to a son of Rajesh. Since Akash is the only son of Rajesh, Neha must be married to Akash. Consequently, Akash is the husband of Neha.

Explanation

Let D, R, S, and G represent the speeds of Duranto, Rajdhani, Shatabdi, and Garib Rath respectively.

Based on the given information, the speed of Duranto is greater than that of Rajdhani: D > R

The speed of Shatabdi is faster than Garib Rath but slower than Rajdhani: R > S > G

Combining these relations establishes the overall speed order: D > R > S > G

From this inequality, Garib Rath has the lowest speed, which identifies it as the slowest train.

Explanation

To arrange the given words in dictionary order, we compare their letters alphabetically from left to right.

Comparing the first two letters of each word, Ab in Abominable comes first, followed by Ac in Accumulate. This places Abominable (ii) first and Accumulate (iv) second.

Next, we compare the remaining two words, Amalgamable (iii) and Amateur (i), which both start with the letters Ama. Comparing their fourth letters, l in Amalgamable comes before t in Amateur, which places Amalgamable (iii) third and Amateur (i) fourth.

Explanation

Both statements are particular positive propositions, from which no negative conclusions can be logically drawn. Since we cannot definitely conclude that some children are not old or that some adults are not old, neither conclusion I nor II follows.

Explanation

The analogy represents the state of birth of the given personalities. Subhas Chandra Bose was born in Cuttack, which is located in Orissa, while Mahatma Gandhi was born in Porbandar, which is located in Gujarat.

Explanation

The letters of the word are divided into two equal halves, and the positions of these halves are interchanged.

In the word ORDERS, the first half is ORD and the second half is ERS. Swapping the halves gives ERS + ORD = ERSORD.

Applying the same pattern to VERMIN, the first half is VER and the second half is MIN. Swapping these halves gives MIN + VER = MINVER.

Explanation

The relationship between the letters in the first pair is determined by adding alternating values of +6 and +5 to the alphabetical positions of each letter.

Applying this logic to MANTLE: M + 6 = S (13 + 6 = 19) A + 5 = F (1 + 5 = 6) N + 6 = T (14 + 6 = 20) T + 5 = Y (20 + 5 = 25) L + 6 = R (12 + 6 = 18) E + 5 = J (5 + 5 = 10)

Applying the same pattern of +6, +5, +6, +5, +6, +5 to PARROT: P + 6 = V (16 + 6 = 22) A + 5 = F (1 + 5 = 6) R + 6 = X (18 + 6 = 24) R + 5 = W (18 + 5 = 23) O + 6 = U (15 + 6 = 21) T + 5 = Y (20 + 5 = 25)

Explanation

The relationship between the first pair of numbers is based on the sum of the digits of the first number, which is then squared to get the second number.

For the number 545: The sum of the digits is 5 + 4 + 5 = 14. Squaring this sum gives 14² = 196.

Applying the same logic to 173: The sum of the digits is 1 + 7 + 3 = 11. Squaring this sum gives 11² = 121.

Explanation

Pongal is a harvest festival celebrated primarily in Tamil Nadu to mark the harvesting of crops, whereas the other options are traditional Indian dance forms.

Explanation

In the alphabetical series where A = 1, B = 2, ..., Z = 26, the positions of the letters in the pair PE are P = 16 and E = 5, yielding a difference of 16 - 5 = 11. For the remaining pairs, the difference between the positional values of the two letters is consistently 9.

Explanation

The number 719 is not a perfect cube, whereas the other numbers are perfect cubes of integers, specifically 8³ = 512, 6³ = 216, and 7³ = 343.

Explanation

The sum of the digits of the number 9362 is 20 (9 + 3 + 6 + 2 = 20), whereas the sum of the digits of all the other numbers is 14 (2 + 5 + 4 + 3 = 14, 2 + 1 + 9 + 2 = 14, and 3 + 7 + 1 + 3 = 14).
