Explanation

By assigning numerical values to each letter of the word based on its position in the English alphabetical order where A = 1, B = 2, up to Z = 26, the sum of the letter positions for the word BOTTOM is:

B + O + T + T + O + M = 2 + 15 + 20 + 20 + 15 + 13 = 85

Applying the same logic to the word DRUM, the sum of the letter positions is:

D + R + U + M = 4 + 18 + 21 + 13 = 56

Explanation

The relation between the first two numbers is established by reversing the order of the digits. Reversing the digits of the number 523 gives 325. Applying the same logic to the number 603, reversing its digits gives 306.

Explanation

AIDS is an infectious disease caused by the Human Immunodeficiency Virus (HIV) that severely damages the immune system. It is classified as a viral infection, making it distinct from nutritional deficiency diseases.

Explanation

The consecutive letters in DEF have a constant difference of 1, where D is 4, E is 5, and F is 6. In contrast, all the other options consist of letters with a constant difference of 3.

Explanation

In the number 327, the last two digits form the cube of the first digit (3³ = 27), whereas in the other numbers, the last two digits represent the square of the first digit.

Explanation

The sum of the digits of 7361 is 17 (7 + 3 + 6 + 1 = 17), which is not divisible by 3. For all the other given numbers, the sum of their digits is 21, which makes them divisible by 3. This makes 7361 the odd number in the set.

Explanation

The directional relationship between two points is always diametrically opposite when viewed from one to the other. On a standard compass, North-West and South-East are directly opposite directions. Since the boy is standing in the north-west direction relative to the girl, the girl must be located in the opposite direction relative to the boy, which is south-east.

Explanation

The given sequence represents the consecutive winners of the Men's Cricket World Cup in chronological order. Following West Indies in 1979, India in 1983, and Australia in 1987, the next Cricket World Cup tournament was held in 1992, which was won by Pakistan. This completes the sequence leading up to Sri Lanka's tournament victory in 1996.

Explanation

The series is formed by adding 5 to the alphabetical position of each letter in the preceding term.

The numerical positions of the letters are: R = 18, S = 19 W = 23, X = 24 B = 2, C = 3

Following this pattern: For the first letter: B (2) + 5 = G (7) For the second letter: C (3) + 5 = H (8)

The next term is GH.

Explanation

By converting the letters to their corresponding alphabetical positions where A = 1, B = 2, and so on up to Z = 26, the series can be analyzed in two parts.

For the first letter of each term, the positions are 1 (A), 10 (J), 18 (R), and 25 (Y). The differences between consecutive terms decrease by 1 each time: 10 − 1 = 9 18 − 10 = 8 25 − 18 = 7 Following this pattern, the next difference must be 6. Adding 6 to 25 gives 31. Subtracting 26 for the alphabetical cycle yields 5, which corresponds to the letter E.

For the second letter of each term, the positions are 2 (B), 8 (H), 13 (M), and 17 (Q). The differences between consecutive terms decrease by 1 each time: 8 − 2 = 6 13 − 8 = 5 17 − 13 = 4 Following this pattern, the next difference must be 3. Adding 3 to 17 gives 20, which corresponds to the letter T.

Combining both parts gives the term ET.

Explanation

The given series increases by successive powers of 2. The difference between consecutive terms is as follows: 3 - 2 = 1 = 2⁰ 5 - 3 = 2 = 2¹ 9 - 5 = 4 = 2² 17 - 9 = 8 = 2³

Following this pattern, the next difference in the series must be 2⁴ = 16. Adding this to the last term gives 17 + 16 = 33.

Alternatively, each term can be obtained by multiplying the previous term by 2 and subtracting 1: 2 × 2 - 1 = 3 3 × 2 - 1 = 5 5 × 2 - 1 = 9 9 × 2 - 1 = 17 17 × 2 - 1 = 33

Explanation

The first statement is an I-type proposition stating that some books are toys. By the standard rules of syllogism, an I-type proposition can be directly converted into another I-type proposition by swapping the subject and the predicate. Therefore, "Some books are toys" immediately converts to "Some toys are books," which means Conclusion II definitely follows. Combining "Some books are toys" with "No toy is red" only yields the conclusion "Some books are not red," meaning Conclusion I does not follow.

Explanation

Let the runs scored by Farhan, Raju, Simran, and Nitu be represented by F, R, S, and N respectively.

According to the first statement, Farhan scored more runs than Raju, which is written as F > R.

According to the second statement, Simran scored more runs than Nitu but fewer runs than Raju, which is written as R > S > N.

Combining these two relationships, we get the overall sequence F > R > S > N, which shows that F represents the highest score.

Explanation

To arrange the words in alphabetical order as they appear in a dictionary, they are compared letter by letter.

First, we compare Cease and Cement which both start with Ce. Comparing their third letters, a in Cease comes before m in Cement, placing Cease (i) before Cement (iv).

Next, we compare Consecutive and Constructive which both start with Cons. Comparing their fifth letters, e in Consecutive comes before t in Constructive, placing Consecutive (ii) before Constructive (iii).

Combining these steps, the complete dictionary order of the words is Cease (i), Cement (iv), Consecutive (ii), and Constructive (iii).

Explanation

By comparing the letters of the given words with their corresponding numerical codes, a direct letter-to-digit mapping can be established:

From DIAMOND (coded as 4895064): D = 4 I = 8 A = 9 M = 5 O = 0 N = 6

From GAME (coded as 7953): G = 7 A = 9 M = 5 E = 3

The common letters A (9) and M (5) are consistent in both words. Applying this mapping to the word MANGO: M = 5 A = 9 N = 6 G = 7 O = 0

Combining these digits in order gives the code 59670.

Explanation

The numbers in each column follow a pattern where the square of the first number added to the second number yields the third number.

In the first column: 13² + 5 = 169 + 5 = 174

In the second column: 17² + 9 = 289 + 9 = 298

In the third column, the same logic gives: 20² + 10 = 400 + 10 = 410

Explanation

By decoding the symbols to their respective mathematical operations: | represents division (÷) represents subtraction (-) @ represents addition (+) % represents multiplication (×)

Substituting these operations into the given expression: 516 ÷ 6 - 11 + 50 × 4

Applying the BODMAS rule: First, perform division: 516 ÷ 6 = 86

Next, perform multiplication: 50 × 4 = 200

Finally, perform the addition and subtraction: 86 - 11 + 200 = 275

Explanation

By checking the rows and columns for each letter in the word FRIEND:

F is represented by Row 8, Column 7 in Matrix-II, which gives 87.

R is represented by Row 2, Column 3 in Matrix-I, which gives 23.

I is represented by Row 7, Column 9 in Matrix-II, which gives 79.

E is represented by Row 2, Column 1 in Matrix-I, which gives 21.

N is represented by Row 7, Column 8 in Matrix-II, which gives 78.

D is represented by Row 2, Column 0 in Matrix-I, which gives 20.

Combining these codes gives the sequence 87, 23, 79, 21, 78, 20.

Explanation

The given letter series consists of 12 letters which can be divided into three equal groups of four letters each. By substituting the letters Q, P, R, and Q sequentially into the gaps, the series becomes PQQR PQQR PQQR. This successfully completes the series by repeating the four-letter pattern PQQR three times.

Explanation

Let the starting point be at coordinates (0, 0) on a Cartesian plane. Riya first travels 5 km east, which brings her to (5, 0). She then turns right to head south for 8 km, reaching (5, -8). Next, turning left means heading east again for 4 km, which brings her to (9, -8). She then turns left to head north for 8 km, arriving at (9, 0). Finally, she turns east and travels 5 km, ending at (14, 0). The distance from her starting point (0, 0) to her final position (14, 0) is 14 km.

Explanation

In the given matrices, a letter is represented by its row number followed by its column number. To find the correct representation for the word CRAB, the coordinates of each letter can be retrieved from the matrices. The letter C is located in Matrix-II at row 5 and column 5, representing 55. The letter R is located in Matrix-II at row 5 and column 8, representing 58. The letter A is located in Matrix-I at row 1 and column 0, representing 10. The letter B is located in Matrix-I at row 1 and column 3, representing 13. Combining these values in sequence gives the set 55, 58, 10, 13.

Explanation

The phrase "my father's daughter" refers to the man's sister. The daughter of the man's sister is his niece.

Explanation

Bishnu is the brother of Aryan, and Aryan is the son of Chetan, which means both Aryan and Bishnu are the sons of Chetan. Since Dev is the father of Chetan, Dev is the grandfather of Bishnu. Consequently, Bishnu is the grandson of Dev.

Explanation

In the game of snooker, the primary equipment used to strike the ball is a stick. Similarly, in the game of cricket, the primary equipment used to strike the ball is a bat.

Explanation

The analogy is based on the alphabetical positions of the letters, where a specific mathematical shift is applied to each letter.

In the first pair MT : JW, the position of M is 13 and T is 20. Subtracting 3 from the first letter position (13 - 3 = 10) gives J, and adding 3 to the second letter position (20 + 3 = 23) gives W.

Applying this same rule of -3 to the first letter and +3 to the second letter for RP, where R is 18 and P is 16: Subtracting 3 from the position of R (18 - 3 = 15) gives the letter O. Adding 3 to the position of P (16 + 3 = 19) gives the letter S.

Explanation

Each letter is represented by its numerical position in the English alphabet, where A = 1, B = 2, and so on up to Z = 26.

For the first pair, TZ : W: T = 20 Z = 26 Taking the average of their positions: (20 + 26) / 2 = 23. The 23rd letter of the alphabet is W.

Applying the same logic to the second pair, NT : ?: N = 14 T = 20 Taking the average of their positions: (14 + 20) / 2 = 17. The 17th letter of the alphabet is Q.

Explanation

The relationship in the given analogy is established by multiplying the individual digits of the first number to obtain the second number.

For the first pair, 23: 2 × 3 = 6

Applying the same logic to the second pair, 43: 4 × 3 = 12

Explanation

Kanchenjunga represents a distinct mountain peak, whereas the other three names all refer to the exact same mountain peak, which is the tallest in the world. Chomolungma is its Tibetan name, Sagarmatha is its Nepali name, and Mount Everest is its English name.

Explanation

The letter group LSS is the odd one out because it contains a repeated letter S and the letters do not follow a consecutive alphabetical order, which deviates from the pattern of consecutive three-letter alphabetical sequences.

Explanation

The number 222 is not divisible by 11, whereas all other numbers in the set are completely divisible by 11.

Explanation

In all options except 5789, the product of the last two digits of the number is equal to the first two digits:

For 5687: 8 × 7 = 56 For 4267: 6 × 7 = 42 For 4977: 7 × 7 = 49

For 5789: 8 × 9 = 72, which is not equal to 57.

Explanation

The given series represents the technological progression and evolution of electronic communication and computing devices over time. The telephone represents early wired voice communication, followed by the radio which introduced wireless audio broadcasting. The mobile phone is the logical next step in this evolution, introducing portable, wireless two-way communication. This directly leads to the laptop, which represents advanced portable computing and digital communication.

Explanation

Each term in the series consists of consecutive letters, and the alphabetical positions of the letters increase by a constant pattern.

By analyzing the first letter of each term: A (1) + 5 = F (6) F (6) + 5 = K (11) K (11) + 5 = P (16) P (16) + 5 = U (21)

By analyzing the second letter of each term: B (2) + 5 = G (7) G (7) + 5 = L (12) L (12) + 5 = Q (17) Q (17) + 5 = V (22)

Following this constant addition of 5 to the position of each letter in the preceding term, the next term in the series is UV.

Explanation

The series follows a specific positional pattern for each letter in the terms:

The first letter of each term increases by 1 position in alphabetical order: K (+1) to L, L (+1) to M, and M (+1) to N.

The second letter of each term increases by 2 positions in alphabetical order: R (+2) to T, T (+2) to V, and V (+2) to X.

The third letter of each term increases by 3 positions in alphabetical order: K (+3) to N, N (+3) to Q, and Q (+3) to T.

Combining these patterns gives the next term as NXT.

Explanation

The given series represents the successive powers of 11, where the nth term is given by the formula Tₙ = 11ⁿ.

The first term is 11¹ = 11. The second term is 11² = 121. The third term is 11³ = 1331. The fourth term is 11⁴ = 14641.

Following this pattern, the missing fifth term is 11⁵, which is calculated as 14641 × 11 = 161051.

Explanation

The given statements focus on the presence of happiness around everyone, finding it, and creating it as a state of mind when it cannot be found.

Conclusion I introduces external concepts such as creativity being constructive and the specific effect of the creation process on an individual's satisfaction. Since these details are not mentioned or implied in the premises, this conclusion does not logically follow.

Conclusion II mentions analyzing situational factors to understand happiness. The premises do not discuss situational factors or the analysis of such factors at all. Therefore, this conclusion also does not follow from the given statements.

Explanation

To find the day of the week on 9th October 2008, we calculate the total number of days between 5th September 2008 and 9th October 2008.

The month of September has 30 days. The remaining days in September after 5th September are 30 - 5 = 25 days.

The number of days in October up to the given date is 9 days.

The total number of days is 25 + 9 = 34 days.

Dividing 34 by 7 to find the number of odd days yields 4 weeks and a remainder of 6 odd days.

Adding 6 days to Monday results in Sunday.

Explanation

Comparing the letters of the words from left to right, Sausage (ii) starts with S-a-u, while Savage (i), Savour (iii), and Saviour (iv) start with S-a-v. Since u precedes v in alphabetical order, Sausage (ii) comes first.

Next, comparing the fourth letters of the remaining three words: In Savage (i), the fourth letter is a. In Saviour (iv), the fourth letter is i. In Savour (iii), the fourth letter is o.

Since a comes before i, and i comes before o, the alphabetical order of these three words is Savage (i), Saviour (iv), and Savour (iii).

Combining these results, the correct dictionary order is ii, i, iv, iii.

Explanation

The coding pattern divides the six-letter word into two equal halves of three letters each, and then reverses the order of letters in each half.

For the word RUMOUR: First half: RUM becomes MUR Second half: OUR becomes RUO Combining them gives MURRUO.

Applying the same pattern to RACKET: First half: RAC becomes CAR Second half: KET becomes TEK Combining them gives CARTEK.

Explanation

The pattern in each column follows the relation: the number in the third row is the cube of the sum of the numbers in the first and second rows.

In the first column: (2 + 5)³ = 7³ = 343

In the second column: (3 + 5)³ = 8³ = 512

Applying the same logic to the third column: (6 + 7)³ = 13³ = 2197

Explanation

Substituting the given operations into the expression: B represents ÷ (divide) C represents × (multiply) A represents + (plus) D represents - (minus)

The expression 162 B 27 C 5 A 8 D 35 is rewritten as: 162 ÷ 27 × 5 + 8 - 35

Following the BODMAS rule:

First, perform division: 162 ÷ 27 = 6

Next, perform multiplication: 6 × 5 = 30

Lastly, perform addition and subtraction: 30 + 8 - 35 = 38 - 35 = 3

Explanation

The given letter series can be divided into three groups of four letters each: K _ L _ | K _ L N | _ M _ N

By filling the blanks with the letters M, N, M, K, and L sequentially, we get: K M L N | K M L N | K M L N

This forms a consistent, repeating pattern where the four-letter group K M L N is repeated three times.

Explanation

Let clockwise turns be represented by positive angles and anticlockwise turns by negative angles.

The initial direction is West.

The sequence of turns is: First turn = +45° Second turn = -180° Third turn (90° to the right/clockwise) = +90°

The net change in direction is: 45° - 180° + 90° = -45°

A net change of -45° represents a 45-degree anticlockwise turn. Turning 45 degrees anticlockwise from West points directly to the South-west direction.

Explanation

The letters of the word TURN are coded using the row number first, followed by the column number.

For T, Matrix-II shows Row 8 and Column 5 intersect at the letter T, which corresponds to 85.

For U, Matrix-I shows Row 3 and Column 0 intersect at the letter U, which corresponds to 30.

For R, Matrix-II shows Row 8 and Column 9 intersect at the letter R, which corresponds to 89.

For N, Matrix-I shows Row 2 and Column 3 intersect at the letter N, which corresponds to 23.

Explanation

Ravi is the brother of Shubham, which means they share the same mother. Shubham's mother is the sister-in-law of Shashi, which indicates that Shashi is the sister of Shubham's father. Because Ravi and Shubham are siblings, Shashi is also the sister of Ravi's father, making Shashi the paternal aunt of Ravi.

Explanation

The relationship in the given analogy is State : Capital. Jaipur is the capital of Rajasthan. In the same way, Shillong is the capital of Meghalaya.

Explanation

Each letter in the first group is replaced by its opposite letter from the end of the alphabet, meaning the sum of the position values of the original letter and its corresponding coded letter is 27.

For DHL: D is the 4th letter, and its opposite is W (27 - 4 = 23rd letter). H is the 8th letter, and its opposite is S (27 - 8 = 19th letter). L is the 12th letter, and its opposite is O (27 - 12 = 15th letter).

Applying this same relationship to CFI: C is the 3rd letter, so its opposite is X (27 - 3 = 24th letter). F is the 6th letter, so its opposite is U (27 - 6 = 21st letter). I is the 9th letter, so its opposite is R (27 - 9 = 18th letter).

Explanation

The relationship between the first and second letter groups is established by shifting each letter forward by one position in alphabetical order. Specifically, E plus 1 is F, J plus 1 is K, and O plus 1 is P.

Applying the same logic to the third letter group KPU, each letter is shifted forward by one position: K plus 1 is L, P plus 1 is Q, and U plus 1 is V, yielding the combination LQV.

Explanation

The relationship between the first pair of numbers is established by the formula: Second term = (First term × 4) - 4

Applying this relationship to the first pair: (13 × 4) - 4 = 52 - 4 = 48

Applying the same formula to the second pair: (17 × 4) - 4 = 68 - 4 = 64

Alternatively, the logic can be represented as (First term - 1) × 4: (17 - 1) × 4 = 16 × 4 = 64

Explanation

Meghalaya is a state in India, whereas the other options represent state capitals.
