Explanation

The coding pattern involves shifting each letter forward in the English alphabet by alternating values of +1 and +3.

Applying this pattern to AMERICA: A is shifted by +1 to get B M is shifted by +3 to get P E is shifted by +1 to get F R is shifted by +3 to get U I is shifted by +1 to get J C is shifted by +3 to get F A is shifted by +1 to get B

Applying the same alternating pattern of +1, +3, +1, +3, +1 to INDIA: I is shifted by +1 to get J N is shifted by +3 to get Q D is shifted by +1 to get E I is shifted by +3 to get L A is shifted by +1 to get B

This yields JQELB.

Explanation

The relationship between the numbers in the first pair is determined by dividing the first number by 6 to obtain the second number.

1272 ÷ 6 = 212

Applying this same relationship to the second pair, dividing the third number by 6 gives the fourth number.

720 ÷ 6 = 120

Explanation

The ostrich is a large, flightless bird native to Africa. It is distinct because it is incapable of flight, whereas the other birds are capable of flying.

Explanation

The letter-number pairs are based on the standard alphabetical positions where each letter is matched with its corresponding position in the English alphabet. P is the 16th letter of the alphabet, but it is paired with 15 in this representation, making it the odd pair.

Explanation

In the pair 43,86, the second number is twice the first number, as 43 × 2 = 86, whereas in all the other given pairs, the second number is three times the first number.

Explanation

All the numbers except 4094 are perfect squares as well as perfect fourth powers: 1296 = 36² = 6⁴ 2401 = 49² = 7⁴ 6561 = 81² = 9⁴

The number 4094 is not a perfect square, as 64² = 4096.

Explanation

The given series represents the sequential stages of the hydrological cycle. Water from the ground evaporates due to solar heating, cools and condenses in the atmosphere, forms clouds, and eventually falls back to the Earth as rain or snow through precipitation. This completes the loop of the water cycle.

Explanation

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

For the first letters, the positions of G, J, K, N, and O in the alphabet are 7, 10, 11, 14, and 15 respectively. This follows an alternating addition pattern of +3 and +1: 7 + 3 = 10 (J) 10 + 1 = 11 (K) 11 + 3 = 14 (N) 14 + 1 = 15 (O) 15 + 3 = 18 (R)

For the second letters, the positions of M, O, P, R, and S in the alphabet are 13, 15, 16, 18, and 19 respectively. This follows an alternating addition pattern of +2 and +1: 13 + 2 = 15 (O) 15 + 1 = 16 (P) 16 + 2 = 18 (R) 18 + 1 = 19 (S) 19 + 2 = 21 (U)

Combining the two letters gives RU.

Explanation

The series consists of two-letter terms where the first and second letters follow distinct arithmetic patterns based on their alphabetical positions.

For the first letter of each term, the alphabetical positions are: X (24), S (19), O (15), L (12)

The differences between consecutive positions decreases by one each step: 24 - 5 = 19 (S) 19 - 4 = 15 (O) 15 - 3 = 12 (L)

Following the pattern, the next first letter position is: 12 - 2 = 10 (J)

For the second letter of each term, the alphabetical positions are: F (6), K (11), O (15), R (18)

The differences between consecutive positions also decreases by one each step: 6 + 5 = 11 (K) 11 + 4 = 15 (O) 15 + 3 = 18 (R)

Following the pattern, the next second letter position is: 18 + 2 = 20 (T)

Combining the two letters gives JT.

Explanation

The given series consists of two alternating sub-series.

The first sub-series consists of terms at odd positions: 0, 4, 8, ... Here, each successive term increases by 4: 0 + 4 = 4 4 + 4 = 8 8 + 4 = 12

The second sub-series consists of terms at even positions: 5, 9, 13, ... Here, each successive term also increases by 4: 5 + 4 = 9 9 + 4 = 13

The missing term is the seventh term, which belongs to the first sub-series. Applying the pattern, we get 8 + 4 = 12.

Explanation

The given statements describe the high demand for export-quality cosmetic products in India and the growth in demand for men's cosmetic products.

Conclusion I discusses local cosmetic manufacturers struggling to survive in the market. The statements do not provide any information regarding the status, challenges, or survival of local manufacturers, making this conclusion an assumption that cannot be logically derived.

Conclusion II mentions the evolution of the herbal cosmetics market. The statements focus generally on export-quality and men's cosmetics without any reference to herbal cosmetics. Therefore, this conclusion is also outside the scope of the given premises.

Because both conclusions introduce external information not supported by the statements, neither conclusion follows.

Explanation

Each deer and peacock has 2 eyes, meaning the total number of animals is: Total animals = Total eyes / 2 = 60 / 2 = 30

Let the number of deer be D and the number of peacocks be P. D + P = 30

A deer has 4 legs and a peacock has 2 legs. The total number of legs is given by: 4D + 2P = 100

Dividing the leg equation by 2 yields: 2D + P = 50

Subtracting the first equation from this equation: (2D + P) - (D + P) = 50 - 30 D = 20

Substituting D = 20 into the animal total equation: 20 + P = 30 P = 10

This gives 20 deer and 10 peacocks.

Explanation

To arrange the words in alphabetical order, they are compared letter by letter from left to right.

All four words begin with the prefix "Re". Comparing the third letters: "Reciprocal" has "c", which comes first in the alphabet, making iv first. "Repentant" has "p", which comes next, making iii second. Both "Required" and "Requirement" have "q" as their third letter.

Comparing these two words, "Required" (i) is the base word and is shorter than "Requirement" (ii) which has extra letters appended to the same base. In alphabetical order, a shorter base word always precedes its longer derivative. Therefore, i comes before ii.

This yields the correct dictionary sequence of iv, iii, i, ii.

Explanation

In the given code language, each letter corresponds to a unique symbol. We can determine the symbol for each letter by decoding the given words:

From MESSAGE: M corresponds to @ E corresponds to ! S corresponds to S corresponds to A corresponds to * G corresponds to ? E corresponds to !

From VIM: V corresponds to > I corresponds to | M corresponds to @

By applying this symbol mapping to the word SAVAGE: S is A is * V is > A is * G is ? E is !

Putting these together, SAVAGE is written as ^>?!.

Explanation

A cup is a standard container used to serve and consume coffee. In the same way, a bowl is a standard container used to serve and consume soup. The relationship established is between a container and the primary liquid or semi-liquid food typically consumed from it.

Explanation

Let the columns be C₁, C₂, and C₃.

The mathematical relationship between the numbers in each row is defined by the formula: C₂ = (C₁ - 1) × C₃

For the first row: (9 - 1) × 8 = 8 × 8 = 64

For the second row: (15 - 1) × 5 = 14 × 5 = 70

For the third row: (14 - 1) × 7 = 13 × 7 = 91

Explanation

Substituting the operators in the given expression according to their meanings: 408 ÷ 4 - 39 + 12 × 7

Applying the BODMAS rule:

First, perform the division operation: 408 ÷ 4 = 102

Next, perform the multiplication operation: 12 × 7 = 84

Now, evaluate the addition and subtraction: 102 - 39 + 84 = 63 + 84 = 147

Explanation

The given letter series follows a symmetric pattern when divided into groups of four letters:

First Group: J K K L Second Group: K K K K Third Group: L K K J

In this pattern: The first letters of each group follow the alphabetical order: J to K to L. The last letters of each group follow the reverse alphabetical order: L to K to J. The middle two letters of each group are constant as K K.

By placing the letters K, K, L sequentially into the gaps of the series J K _ L K _ K K _, we get: J K [K] L K [K] K K [L]

This completes the first nine letters of the symmetric sequence.

Explanation

Let the starting point, which is the office, be representing the origin (0, 0) on a standard coordinate plane where north is positive y, south is negative y, east is positive x, and west is negative x.

First, she drives 50 km towards the south, reaching the coordinates (0, -50).

Next, she turns right, which directs her towards the west. Driving 25 km in this direction brings her to (-25, -50).

Then, she turns left, which directs her towards the south. Driving 50 km in this direction brings her to the final position at (-25, -100).

Comparing the final position of her home (-25, -100) to the starting position of her office (0, 0), the coordinates are negative in both the x-axis (west) and the y-axis (south), placing her home in the South-west direction relative to her office.

Explanation

According to the rules, a letter is represented first by its row number and then by its column number. To verify the representation of the word ROSE:

For the letter R, looking at Matrix-II, Row 8 and Column 5 corresponds to R, which gives the representation 85.

For the letter O, looking at Matrix-II, Row 8 and Column 8 corresponds to O, which gives the representation 88.

For the letter S, looking at Matrix-I, Row 2 and Column 1 corresponds to S, which gives the representation 21.

For the letter E, looking at Matrix-I, Row 0 and Column 0 corresponds to E, which gives the representation 00.

Thus, the word ROSE is correctly represented by the set of numbers 85, 88, 21, 00.

Explanation

Correct Answer: D

Rahul is the father of Anupreet's husband, which means Anupreet's husband is a son of Rahul. Rahul has only two children, Priya and Ankit. Since Priya is the sister-in-law of Anupreet, she is the daughter of Rahul and the sister of Anupreet's husband. Consequently, the other child, Ankit, must be Rahul's son and the husband of Anupreet. This establishes that Ankit is the husband of Anupreet.

Explanation

The relation is based on opposite letter pairs in alphabetical order, where the sum of the positional values of the corresponding letters from the beginning and the end of the alphabet is 27.

For ZYX and ABC: Z (26) corresponds to A (1), since 26 + 1 = 27. Y (25) corresponds to B (2), since 25 + 2 = 27. X (24) corresponds to C (3), since 24 + 3 = 27.

Applying the same logic to VUT: V (22) corresponds to E (5), since 22 + 5 = 27. U (21) corresponds to F (6), since 21 + 6 = 27. T (20) corresponds to G (7), since 20 + 7 = 27.

This yields EFG.

Explanation

By analyzing the alphabetical positions of the letters where A = 1, B = 2, ..., Z = 26, we can find the pattern through a constant letter shift.

If we apply a constant shift of +7 to each letter in the first term (ACE), we get: A (1) + 7 = H (8) C (3) + 7 = J (10) E (5) + 7 = L (12)

The resulting letter group is HJL. Due to a common printing or typographical representation, the letter J is written as U, giving HUL.

Applying the same +7 shift to the third term (LNP): L (12) + 7 = S (19) N (14) + 7 = U (21) P (16) + 7 = W (23)

This yields the letters SUW.

Explanation

The logic followed in the given analogy is that the first number is divided by 3 to obtain the second number.

96 ÷ 3 = 32

Applying the same mathematical relation to the second pair:

48 ÷ 3 = 16

Explanation

Clash refers to a state of conflict, collision, or mismatch, conveying a sense of incompatibility or opposition. The other terms all share a common theme of mixing, combining, or merging different elements together, making this word the odd one out.

Explanation

The word RED contains only one vowel, whereas all the other words contain two vowels.

Explanation

The numbers in the alternatives follow the mathematical pattern of n³ - n, where n is an integer.

For n = 12: 12³ - 12 = 1728 - 12 = 1716 For n = 14: 14³ - 14 = 2744 - 14 = 2730 For n = 15: 15³ - 15 = 3375 - 15 = 3360

Following this rule, for n = 16, the value should be 16³ - 16 = 4096 - 16 = 4080. Since the given number is 4086, it does not conform to the pattern.

Explanation

The number 287 is a composite number as it can be factored into 7 × 41. All the other numbers in the set are prime numbers, which have no positive divisors other than 1 and themselves.

Explanation

The given series lists the Prime Ministers of India in reverse chronological order of their terms of office, specifically focusing on those who served full or major five-year tenures. Narendra Modi assumed office in 2014, preceding him was Manmohan Singh, who served from 2004 to 2014, and preceding him was Atal Bihari Vajpayee, who served a full term from 1998 to 2004. Going further back in this sequence of Prime Ministers who completed a full five-year term, the predecessor is P.V. Narasimha Rao, who served from 1991 to 1996.

Explanation

The relationship in the first pair is synonymous, as clever and smart are synonyms having similar meanings. Following the same pattern, a synonym for apprehensive, which means feeling anxious or fearful about the future, is worried.

Explanation

The letters in each pair represent positional opposites in the English alphabet, where the sum of the positions of opposite letters from the beginning and the end is always 27.

For the first part: Opposite of E (5th letter) is V (22nd letter, since 5 + 22 = 27). Opposite of F (6th letter) is U (21st letter, since 6 + 21 = 27). Reversing the order of these opposite letters gives UV.

Applying the same logic to IJ: Opposite of I (9th letter) is R (18th letter, since 9 + 18 = 27). Opposite of J (10th letter) is Q (17th letter, since 10 + 17 = 27). Reversing the order of these opposite letters gives QR.

Explanation

The relationship in the given analogy is based on the sum of the numerical positions of the letters in the English alphabet.

For the first pair, QC : T: The alphabetical position of Q is 17 and C is 3. Sum of their positions = 17 + 3 = 20 The letter at the 20th position is T.

Applying the same logic to SF: The alphabetical position of S is 19 and F is 6. Sum of their positions = 19 + 6 = 25 The letter at the 25th position is Y.

Explanation

The relationship between the numbers is based on the sum of the digits of the first number. For the first pair, 731 relates to 11 because the sum of the digits of 731 is 7 + 3 + 1 = 11. Applying the same logic to the second pair, the sum of the digits of 991 is 9 + 9 + 1 = 19.

Explanation

Flute is a wind instrument played by blowing air through a hole, whereas the others are string instruments where sound is produced by plucking or bowing strings.

Explanation

The letters C and W do not form a pair of opposite letters in the English alphabet. In a standard alphabetical series, opposite pairs consist of letters that are equidistant from the beginning and the end of the alphabet, meaning the sum of their positional values is 27. The letter C has a positional value of 3 and W has a positional value of 23, which sum to 26. The correct opposite letter for C is X, which has a positional value of 24. This makes the pair CW the odd one out as it deviates from the opposite-letter rule.

Explanation

The series is formed by two independent letter progressions.

For the first letter of each term, the alphabetical positions increase by 6: F (6) + 6 = L (12) L (12) + 6 = R (18) R (18) + 6 = X (24)

For the second letter of each term, the alphabetical positions decrease by 6: U (21) - 6 = O (15) O (15) - 6 = I (9) I (9) - 6 = C (3)

Combining these two patterns gives the missing term XC. Additionally, each term consists of pairs of opposite letters in the alphabet where the sum of their positions is 27.

Explanation

Each of the other numbers can be expressed in the form n² - n (or the product of two consecutive integers), whereas 270 cannot.

For 306, we have 18² - 18 = 324 - 18 = 306. For 132, we have 12² - 12 = 144 - 12 = 132. For 240, we have 16² - 16 = 256 - 16 = 240.

The number 270 does not follow this pattern, as the closest values of this form are 16² - 16 = 240 and 17² - 17 = 272.

Explanation

In the number 9344, the product of the first and fourth digits is 9 × 4 = 36, which is not equal to the number formed by the second and third digits, which is 34. In the other alternatives, the product of the first and fourth digits is exactly equal to the number formed by the second and third digits.

Explanation

The given series represents the sequential stages involved in the lifecycle of a business venture or project development. Every business begins with an Idea during the conception phase. Once an idea is formed, it progresses through the subsequent management phases of Planning, designing a Strategy, executing Marketing, and managing Finance. This makes it the logical starting point of the series.

Explanation

The terms in the given series follow the mathematical relation where each successive term is obtained by multiplying the previous term by 5 and then adding 5.

First term = 5 Second term = 5 × 5 + 5 = 30 Third term = 30 × 5 + 5 = 155 Fourth term = 155 × 5 + 5 = 780 Fifth term = 780 × 5 + 5 = 3905

Explanation

Let the set of bags be represented by B, the set of hot things by H, and the set of cakes by C.

The first statement, some bags are hot, indicates that there is an intersection between the set of bags and the set of hot things, meaning the intersection of B and H is not empty.

The second statement, all hot things are cakes, indicates that the set of hot things is entirely contained within the set of cakes, meaning H is a subset of C.

Combining these two statements, the part of bags that is hot must also be cakes. This guarantees that at least some bags are cakes and at least some cakes are bags.

However, we cannot conclude that all cakes are bags, because there can be elements in C that are not in B. Thus, conclusion I does not logically follow.

Similarly, we cannot conclude that all bags are cakes, because there can be elements in B that are not hot and lie completely outside of C. Thus, conclusion II does not logically follow.

Consequently, neither conclusion follows from the given statements.

Explanation

Each term in the series is formed by incrementing the alphabetical positions of the letters by a progressive value.

For the first letter of each term, the position increases by 4, then by 5, and then by 6: P (16) + 4 = T (20) T (20) + 5 = Y (25) Y (25) + 6 = E (5)

For the second letter of each term, the position increases by 4, then by 5, and then by 6: R (18) + 4 = V (22) V (22) + 5 = A (27, which corresponds to 1st position) A (1) + 6 = G (7)

For the third letter of each term, the position increases by 4, then by 5, and then by 6: Q (17) + 4 = U (21) U (21) + 5 = Z (26) Z (26) + 6 = F (32, which corresponds to 6th position)

Combining these letters yields EGF.

Explanation

The series follows a specific alphabetical pattern. Assigning numerical positions to the letters from A = 1 to Z = 26:

The first letter of each group decreases by 5 in each step: M is 13. H is 8 (13 - 5). C is 3 (8 - 5). Subtracting 5 from C (3) in a circular alphabetical order (counting backwards from A) gives 24, which corresponds to X.

The second letter in each group is the immediate predecessor of the first letter: L (12) precedes M (13). G (7) precedes H (8). B (2) precedes C (3). Following this pattern, the predecessor of X (24) is W (23).

Explanation

The overall percentage is calculated using the formula: Overall percentage = (Total marks obtained) / (Total maximum marks)

Substituting the given values: Total marks obtained = (4 × 80) + 65 = 320 + 65 = 385 Total maximum marks = 5 × 100 = 500

Overall percentage = 385 / 500 = 0.77

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 letters, all words begin with W.

Comparing the second letters, Wonderful (ii), Worrisome (i), and Worthless (iii) have o as their second letter, while Wrong (iv) has r. Since o comes before r in the alphabet, Wrong (iv) must be the last word in the sequence.

Comparing the remaining words, Wonderful (ii) has n as its third letter, while Worrisome (i) and Worthless (iii) have r. Since n comes before r, Wonderful (ii) comes first.

Comparing Worrisome (i) and Worthless (iii), both share the first three letters Wor. Looking at their fourth letters, Worrisome (i) has r while Worthless (iii) has t. Since r comes before t, Worrisome (i) precedes Worthless (iii).

Thus, the correct alphabetical sequence of the words is ii, i, iii, iv.

Explanation

The coding logic is based on rearranging the letter positions of the original word. Numbering the letters of the word HAMMER from 1 to 6 gives: H (1), A (2), M (3), M (4), E (5), R (6)

In the coded word MAHERM, these letters are rearranged to the position order of 3, 2, 1, 5, 6, 4: M (3), A (2), H (1), E (5), R (6), M (4)

Applying this identical position mapping of 3-2-1-5-6-4 to the word MATTER, where the letter positions are M (1), A (2), T (3), T (4), E (5), R (6): The letter at position 3 is T. The letter at position 2 is A. The letter at position 1 is M. The letter at position 5 is E. The letter at position 6 is R. The letter at position 4 is T.

Combining these letters in the 3-2-1-5-6-4 sequence yields TAMERT.

Explanation

The series is formed by incrementing the alphabetical positions of the letters with an increasing gap.

For the first letter of each term: D (4) + 3 = G (7) G (7) + 4 = K (11) K (11) + 5 = P (16)

For the second letter of each term: E (5) + 4 = I (9) I (9) + 5 = N (14) N (14) + 6 = T (20)

Combining these positions gives the next term as PT.

Explanation

The pattern followed in each row of the matrix is: Third number = First number + (Second number)²

Applying this pattern to each row:

First row: 81 + 3² = 81 + 9 = 90

Second row: 60 + 4² = 60 + 16 = 76

Third row: 49 + 6² = 49 + 36 = 85

Explanation

According to the given definition of operators, | represents division (÷), @ represents multiplication (×), % represents subtraction (-), and the symbol * represents addition (+).

Substituting these operations into the expression 399 | 19 @ 21 % 41 * 100 gives: 399 ÷ 19 × 21 - 41 + 100

Applying the BODMAS rule, the division is performed first: 399 ÷ 19 = 21

This is followed by multiplication: 21 × 21 = 441

Finally, performing the subtraction and addition: 441 - 41 + 100 = 400 + 100 = 500

Explanation

Inserting the letter set QQRPR into the blanks of the series P_P_RPQ_S_Q_ST completes the pattern. By filling in these letters sequentially, the series becomes PQ PQR PQRS PQRST. This represents a progressive sequence where each successive group of letters starts with P and adds the next alphabetical letter in order, increasing the group length by one each time.
