Explanation

Narora is the site of the Narora Atomic Power Station, a major nuclear power plant located in Uttar Pradesh, making it distinct as a nuclear energy hub rather than a coal mining region.

Explanation

The letter group NOP consists of consecutive English alphabet letters with a positional difference of +1, which is N to O to P. This does not match the pattern of the remaining groups, which all have alternate letters with a constant positional difference of +2.

Explanation

The sum of the digits of the number 1356 is 15 (1 + 3 + 5 + 6 = 15), while the sum of the digits for each of the other three numbers is 25.

Explanation

The number 75 is a composite number since it has divisors other than 1 and itself, specifically 3, 5, 15, and 25, making it different from the other numbers which are all prime numbers.

Explanation

A wallet is a container used for carrying and storing money. Similarly, a quiver is a portable case or container specifically designed for carrying and storing arrows.

Explanation

The relationship in the given pair is based on opposite pairs of letters in the English alphabet, where the sum of the positional values of the corresponding letters is equal to 27.

For the first pair HJ and SQ: The positional value of H is 8, and its opposite letter is S because 27 - 8 = 19. The positional value of J is 10, and its opposite letter is Q because 27 - 10 = 17.

Applying the same logic to OP: The positional value of O is 15, and its opposite letter is L because 27 - 15 = 12. The positional value of P is 16, and its opposite letter is K because 27 - 16 = 11.

Explanation

The given series lists the Presidents of India in reverse chronological order. Pranab Mukherjee was the thirteenth President (2012-2017), preceded by Pratibha Patil, who served as the twelfth President (2007-2012). Before her, APJ Abdul Kalam served as the eleventh President (2002-2007). Following this backward sequence, the next term must be the tenth President of India, which is K.R. Narayanan, who held office from 1997 to 2002.

Explanation

By converting the letters to their respective numerical positions in the English alphabet where A = 1, B = 2, and so on up to Z = 26: C = 3 T = 20 W = 23

The relationship is established by adding the numerical positions of the first two letters: 3 + 20 = 23, which represents the letter W.

Applying this same logic to QR: Q = 17 R = 18 17 + 18 = 35

Since 35 exceeds the 26 letters of the alphabet, we subtract 26 to cycle back to the beginning: 35 - 26 = 9

The 9th letter of the alphabet is I.

Explanation

The relationship in the first pair is obtained by adding the individual digits of the first number to get the second number: 2 + 7 = 9

Applying the same mathematical logic to the second pair: 4 + 5 = 9

This gives the corresponding number for 45 as 9.

Explanation

Arun Jaitley is the odd one out because he never held the office of the Prime Minister of India, having instead served as a cabinet minister holding portfolios such as Finance and Defence, whereas the other individuals listed all served as the Prime Minister of India.

Explanation

TP is the odd pair because the alphabetical position of T is 20 and P is 16, giving a difference of 4 (20 - 16 = 4), whereas all other pairs have a constant difference of 3 between their first and second letters.

Explanation

The sum of the digits of 657 is equal to 18, which is calculated as 6 + 5 + 7. For all other numbers, the sum of the digits is equal to 19, which is calculated as 9 + 6 + 4 for 964, 8 + 8 + 3 for 883, and 4 + 7 + 8 for 478.

Explanation

The group 6, 9, 11 does not form a Pythagorean triplet. In a Pythagorean triplet, the sum of the squares of the first two numbers is equal to the square of the third number. For this group, 6² + 9² = 36 + 81 = 117, which is not equal to 11² = 121, unlike the other triplets.

Explanation

The given series represents the chronological order of the Presidents of India from the inception of the republic. Dr. Rajendra Prasad served as the first President of India from 1950 to 1962. He was succeeded by S. Radhakrishnan, who served from 1962 to 1967, followed by Zakir Husain from 1967 to 1969, V.V. Giri from 1969 to 1974, and Fakhruddin Ali Ahmed from 1974 to 1977. This establishes the chronological sequence starting with Dr. Rajendra Prasad.

Explanation

The series is formed by applying a specific pattern to the first and second letters of each term separately.

For the first letter of each term, the positions of the letters in the English alphabet are: G = 7 H = 8 J = 10 M = 13

The differences between successive first letters increase by 1 each time: 7 + 1 = 8 (H) 8 + 2 = 10 (J) 10 + 3 = 13 (M) 13 + 4 = 17 (Q)

For the second letter of each term, the positions of the letters in the English alphabet are: M = 13 M = 13 N = 14 P = 16

The differences between successive second letters also increase by 1 each time, starting from 0: 13 + 0 = 13 (M) 13 + 1 = 14 (N) 14 + 2 = 16 (P) 16 + 3 = 19 (S)

Combining both letters gives QS.

Explanation

The series is formed by two alternating sequences for both the first and second letters of each term.

For the first letters of the terms: The first, third, and fifth terms form the sequence C → D → E, where each letter increases by 1 position in alphabetical order. The second and fourth terms form the sequence E → F, also increasing by 1 position. Thus, the first letter of the missing fifth term is E.

For the second letters of the terms: The first, third, and fifth terms form the sequence S → T → U, where each letter increases by 1 position in alphabetical order. The second and fourth terms form the sequence C → D, also increasing by 1 position. Thus, the second letter of the missing fifth term is U.

Combining these two letters gives the term EU.

Explanation

The pattern of the given series involves dividing each term by a divisor that increases by a power of 10 at each step:

1st term = 1000 2nd term = 1000 ÷ 10¹ = 100 3rd term = 100 ÷ 10² = 1 4th term = 1 ÷ 10³ = 0.001

Following this pattern, the next term is obtained by dividing the third term by 1000.

Explanation

The series follows a pattern where each letter in a term is shifted forward by 4 positions in alphabetical order to obtain the corresponding letter of the next term.

For the first letter of each term, the positions increase by 4: D (4) + 4 = H (8) H (8) + 4 = L (12) L (12) + 4 = P (16)

For the second letter of each term, the positions also increase by 4: E (5) + 4 = I (9) I (9) + 4 = M (13) M (13) + 4 = Q (17)

Explanation

The given statements describe a planned government legal framework designed to define the liabilities, security, and obligations of payment companies, covering various electronic and digital payment modes.

Conclusion I follows because defining security standards and liabilities for electronic transactions and e-walments is inherently aimed at securing transactions, safeguarding user data, and preventing security breaches such as data theft.

Conclusion II follows directly because the core purpose of designing a legal framework to define security and obligations is to clarify, specify, and standardize the parameters governing transactional security, user privacy, and data confidentiality.

Explanation

The number of days remaining in July after the 7th of July is 24 days, since July has 31 days. The number of days in August up to the 15th of August is 15 days.

The total number of days between these two dates is 24 + 15 = 39 days.

Dividing the total days by 7 to find the number of odd days: 39 ÷ 7 = 5 weeks with a remainder of 4 odd days.

Adding 4 days to Wednesday gives Sunday.

Explanation

To arrange the words in alphabetical order as they appear in a dictionary, we compare them letter by letter from left to right. All four words begin with the same letters Be. Comparing their third letters, we have g in Began, n in Beneath, r in Bermuda, and s in Beside. Alphabetical comparison of these letters yields the order g, n, r, s, which corresponds to the sequence ii, iii, i, iv.

Explanation

The logic used in the code language is reversing the order of the letters of the word. Reversing the word STRAIGHT gives THGIARTS. Following the same logic, reversing the letters of the word QUALIFIED gives DEIFILAUQ.

Explanation

The numbers in each column follow a pattern where the third number is the product of the first two numbers.

For the first column: 7 × 13 = 91

For the second column: 12 × 18 = 216

Applying this pattern to the third column: 24 × 3 = 72

Explanation

Substituting the given operator meanings into the expression 90 B 18 C 4 A 8 D 12 gives: 90 ÷ 18 × 4 + 8 - 12

Following the BODMAS rule, division is performed first: 90 ÷ 18 = 5, which simplifies the expression to 5 × 4 + 8 - 12.

Next, multiplication is performed: 5 × 4 = 20, which simplifies the expression to 20 + 8 - 12.

Then, addition is performed: 20 + 8 = 28, simplifying the expression to 28 - 12.

Finally, subtraction is performed: 28 - 12 = 16.

Explanation

The given letter series follows a pattern where the block of four letters KLMN alternates with its reversed sequence NMLK.

The pattern is: KLMN | NMLK | KLMN

Placing the letter set LNKLN into the gaps completes this repeating pattern: First block: KLMN Second block: NMLK Third block: KLMN

Explanation

A standard compass has directions in the clockwise order of North, East, South, and West, each separated by 90 degrees.

According to the question, in the actual direction of South, Mohan's compass shows West. This indicates that the compass markings are rotated 90 degrees clockwise relative to the actual directions.

To go towards the actual North, which is 180 degrees opposite to actual South, Mohan must head in the direction opposite to the compass reading of West. On any compass, the direction opposite to West is East. Therefore, to travel towards the actual North, Mohan should go in the direction shown as East on his compass.

Explanation

The letters of the word STALL are represented by the following row and column index pairs from Matrix-I and Matrix-II:

S is represented by row 7 and column 6 (76) in Matrix-II. T is represented by row 9 and column 7 (97) in Matrix-II. A is represented by row 0 and column 0 (00) in Matrix-I. L is represented by row 3 and column 1 (31) in Matrix-I. L is represented by row 1 and column 3 (13) in Matrix-I.

Combining these codes gives the sequence: 76, 97, 00, 31, 13.

Explanation

Akram's sister's husband is Ibrahim's father, which means Akram's sister is Ibrahim's mother. Since Ibrahim is the son of Akram's sister, Ibrahim is Akram's nephew.

Explanation

The position values of the letters in the English alphabet are used to find the pattern.

For the first letter of each term: P (16) + 6 = 22 (V) V (22) + 6 = 28, which wraps around the 26-letter alphabet to 2 (B) B (2) + 6 = 8 (H)

For the second letter of each term: R (18) + 6 = 24 (X) X (24) + 6 = 30, which wraps around to 4 (D) D (4) + 6 = 10 (J)

Adding 6 to the alphabetical positions of both letters in the term BD yields the next term, HJ.

Explanation

Each term in the series is obtained by multiplying the preceding term by 3 and adding 1. The relationship between consecutive terms follows the formula:

Next term = (Current term × 3) + 1

Applying this pattern to the given series: 13 = (4 × 3) + 1 40 = (13 × 3) + 1 121 = (40 × 3) + 1

Following the same logic to find the missing term: 121 × 3 + 1 = 363 + 1 = 364

Explanation

To determine which conclusions follow, we must rely solely on the information provided in the statements.

Conclusion I does not follow because the statements only mention that the cases are based on evidence. They do not specify that this evidence is derived from tests that were conducted. The evidence could instead refer to witness testimonies, investigative reports, or confessions.

Conclusion II does not follow because the fact that 28 athletes are facing legal cases is a specific number. This limited data does not provide a sufficient basis to generalize that doping is a very common practice among athletes today.

Since neither conclusion can be logically deduced from the given premises, neither I nor II follows.

Explanation

Correct Answer: D

To find the person with the highest share of land, the relationships can be represented as inequalities using the initials of each person.

Raju has more share of land than Sundar but less than Prem: P > R > S

Hari has less share of land than Sundar: S > H

Ompal has the least share of land among everyone.

Combining these statements gives the complete descending order of land ownership: P > R > S > H > O

This sequence shows that Prem holds the maximum share of land.

Explanation

To arrange the words in alphabetical order as they appear in a dictionary, they are compared letter by letter from left to right. All four words begin with the prefix Perm. Comparing the fifth letter, Permafrost, Permanence, and Permanent have the letter a, while Permeability has the letter e. Since a precedes e in the alphabet, Permeability is placed last.

Next, comparing the sixth letter of the remaining three words, Permafrost has the letter f, whereas Permanence and Permanent both have the letter n. Since f comes before n, Permafrost is positioned first in the sequence.

Finally, comparing Permanence and Permanent, the first eight letters are identical. At the ninth position, Permanence has the letter c and Permanent has the letter t. Since c precedes t, Permanence comes before Permanent.

This establishes the correct alphabetical sequence as Permafrost, Permanence, Permanent, and Permeability, which matches the order iii, i, ii, iv.

Explanation

The code for each letter is directly mapped to a specific digit based on its position in the given words.

In the word TOAST, which is coded as 03210: T corresponds to 0, O corresponds to 3, A corresponds to 2, and S corresponds to 1.

In the word RIGID, which is coded as 45759: R corresponds to 4, I corresponds to 5, G corresponds to 7, and D corresponds to 9.

By applying this direct letter-to-digit mapping to the word DOOR: The letter D is represented by 9, the letter O is represented by 3, and the letter R is represented by 4.

This gives the code 9334.

Explanation

Each column in the matrix represents a Pythagorean triplet where the sum of the squares of the numbers in the first and second rows equals the square of the number in the third row: Row 1² + Row 2² = Row 3²

First column: 3² + 4² = 9 + 16 = 25 = 5²

Second column: 12² + 5² = 144 + 25 = 169 = 13²

Third column: 24² + 7² = 576 + 49 = 625 = 25²

Explanation

Replacing the given operators with their designated mathematical operations in the original expression:

81 × 9 + 10 - 6 ÷ 5

According to the instructions: "×" is replaced by "÷" "+" is replaced by "-" "-" is replaced by "×" "÷" is replaced by "+"

Substituting these operators gives the new expression: 81 ÷ 9 - 10 × 6 + 5

Applying the BODMAS rule, solve the division first: 81 ÷ 9 = 9

Substitute this back into the expression: 9 - 10 × 6 + 5

Next, perform the multiplication: 10 × 6 = 60

Substitute this value: 9 - 60 + 5

Finally, perform addition and subtraction from left to right: 9 + 5 - 60 = 14 - 60 = -46

Explanation

The analogy represents the relationship between a country and its official national currency. The official currency of Iraq is the Iraqi Dinar. Similarly, the official currency of Korea is the Won.

Explanation

The relationship is established by first reversing the order of the letters of the given term and then adding 8 to the alphabetical position of each letter.

For the second pair, GMA is reversed to AMG. Adding 8 to the position of each letter gives: A (1) + 8 = 9 (I) M (13) + 8 = 21 (U) G (7) + 8 = 15 (O) This results in IUO (typographically written as ILO in the question).

Applying the same logic to the first pair, AOE is reversed to EOA. Adding 8 to the position of each letter gives: E (5) + 8 = 13 (M) O (15) + 8 = 23 (W) A (1) + 8 = 9 (I) This results in MWI.

Explanation

The given letter series has four gaps: a_c_e_b_de.

When the letters from the set bdac are placed sequentially into these gaps, the complete series becomes: a b c d e a b c d e

This forms a repeating pattern of the five-letter sequence abcde.

Explanation

The letters in the first term deF are consecutive alphabetical letters (D, E, F) with the casing pattern lowercase-lowercase-uppercase. The second term Ihg contains the next three alphabetical letters (G, H, I) written in reverse order (I, H, G) with the casing pattern uppercase-lowercase-lowercase.

Applying the same logic to the third term wxY, which consists of consecutive letters (W, X, Y) with the casing pattern lowercase-lowercase-uppercase, the next term must contain the next three letters in the alphabetical cycle (Z, A, B) written in reverse order (B, A, Z) with the casing pattern uppercase-lowercase-lowercase. This gives the term Baz.

Explanation

The pattern followed in the given analogy is based on the mathematical relation x² : (x + 2)².

For the first pair: 81 = 9² 121 = (9 + 2)² = 11²

Applying the same relation to the second pair: 49 = 7² ? = (7 + 2)² = 9² = 81

Explanation

A helicopter is an aerial vehicle designed to fly and travel through the air. It utilizes rotating blades or rotors to generate lift and thrust, enabling vertical takeoff and landing, which distinguishes it from land-based transportation.

Explanation

The letter group MNO consists of consecutive English alphabetical letters with a step difference of +1 between successive positions (M = 13, N = 14, O = 15), while the remaining groups follow a pattern of a constant step difference of +3. This makes MNO the odd group out.

Explanation

In the number 7240, the product of the first two digits does not equal the number formed by the last two digits. In the other numbers, the product of the first two digits equals the number represented by the last two digits, where 5 × 2 = 10, 8 × 4 = 32, and 8 × 6 = 48. In contrast, for 7240, the multiplication of the first two digits 7 × 2 equals 14, which does not equal the last two digits 40.

Explanation

The number 198 is not a perfect power of any integer, whereas the other numbers are all perfect squares or cubes of integers, such as 81 which is 9², 125 which is 5³, and 64 which is 8² or 4³.

Explanation

The series follows a pattern based on the starting letters of each three-letter group and the consecutive nature of the letters within each group.

Analyzing the first letters of each term: i (9th letter) to m (13th letter) is +4 m (13th letter) to l (12th letter) is -1 l (12th letter) to p (16th letter) is +4 p (16th letter) to o (15th letter) is -1

Following this alternating pattern of adding 4 and subtracting 1, the starting letter of the missing term is obtained by adding 4 to o (15th letter), which gives s (19th letter).

Since each term in the series consists of three consecutive alphabetical letters, the term starting with s is s, t, u.

Explanation

The given series consists of pairs of letters following two independent alphabetical patterns.

The first letter of each term increases sequentially in alphabetical order, starting with A, which is followed by B, then C, and finally D.

The second letter of each term decreases sequentially in reverse alphabetical order, starting with Z, which is followed by Y, then X, and finally W.

Combining these two patterns, the next term in the series is DW.

Explanation

The differences between consecutive terms in the given series increase by 1 at each step. Calculating the difference between each term:

32 - 23 = 9 42 - 32 = 10 53 - 42 = 11 65 - 53 = 12

Following this pattern, the next difference in the sequence must be 13. Adding 13 to the last term:

65 + 13 = 78

Explanation

Statement I establishes a direct comparison between life and a journey, specifying that this journey is composed of known people, partially known people, and strangers. Since these individuals accompany us through the journey of life, they act as our journey mates, which directly supports the deduction that the importance of people in life is considerable. Therefore, conclusion I logically follows from the first statement. Conversely, the given statements contain no information regarding life lessons or facing difficulties, meaning conclusion II cannot be logically derived from the premises.

Explanation

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

Amit starts by facing north. He turns 90° right, which means he is now facing east. Walking 50 m east brings him to the coordinates (50, 0).

Next, he turns south and walks 50 m, which brings him to the coordinates (50, -50).

From this position facing south, turning right means he now faces west. Walking 50 m west brings him to the coordinates (0, -50).

Finally, walking 50 m north from (0, -50) brings him back to the starting point (0, 0).
