Explanation

Standard cardinal and intercardinal directions can be represented by angles measured clockwise from North (0°): North = 0° North-East = 45° East = 90° South-East = 135° South = 180° South-West = 225° West = 270° North-West = 315°

The given shift shows: North-West (315°) becomes South (180°), which represents a rotation of 135° anti-clockwise (315° - 135° = 180°). North-East (45°) becomes West (270°), which is also a rotation of 135° anti-clockwise (45° - 135° = -90° = 270°).

Applying the same 135° anti-clockwise rotation to East (90°): 90° - 135° = -45° = 315°, which corresponds to North-West.

Explanation

Ram's father's brother is Ram's paternal uncle.

The mother-in-law of Ram's uncle is the mother of Ram's uncle's wife.

Since the lady's mother is the mother-in-law of Ram's uncle, the lady's mother is the mother of Ram's uncle's wife. This means the lady in the photograph is Ram's uncle's wife.

Therefore, the lady is Ram's aunt.

Explanation

Sukhoi is a well-known military aircraft developed and manufactured by Russia. Similarly, Tejas is a light combat aircraft developed and manufactured by India.

Explanation

In the second pair DE : HJ, the alphabetical positions of the letters in the first term are multiplied by 2 to obtain the letters of the second term: D (4) × 2 = H (8) E (5) × 2 = J (10)

In the first pair GE : TV, the letters of the first term and the second term are opposite (reverse) pairs in the alphabetical order, where the sum of the positions of the opposite letters is always 27: G (7) + T (20) = 27 E (5) + V (22) = 27

Thus, GE is the correct term that relates to TV.

Explanation

The relationship between the first and third terms is a shift of -6 positions in the alphabet: H - 6 = B and J - 6 = D. Applying the same shift of -6 to the second term (NO) gives N - 6 = H and O - 6 = I, resulting in HI.

Explanation

The relationship is based on the sum of the digits of the first number. For 432, the sum of the digits is 4 + 3 + 2 = 9, and applying the same logic to 237, the sum of the digits is 2 + 3 + 7 = 12.

Explanation

Gateway of India is located in Mumbai, Maharashtra, while the other monuments are located in Delhi.

Explanation

The alphabetical positions of the letters N and O are 14 and 15, representing a consecutive difference of 1. All other pairs have a positional difference of 2 between their first and second letters.

Explanation

In the given number classification, the product of the first two digits in each number equals the number formed by the last two digits. For 3421, the product of the first two digits is 3 × 4 = 12, which is not equal to the last two digits 21. Therefore, it does not follow the common pattern.

Explanation

The number 43 is a prime number because its only divisors are 1 and itself. The other numbers are composite numbers.

Explanation

The given series represents units of liquid volume arranged in an increasing order of their capacity. An ounce represents approximately 0.03 liters. A liter is equal to 1 liter. A gallon is larger, representing approximately 3.785 liters. To continue this pattern of increasing volume, the next term must be larger than a gallon. A decaliter, which is equal to 10 liters, is greater than a gallon and logically completes this ascending sequence.

Explanation

The pattern in the series is to multiply each term by consecutive integers starting from 2 and then add the same multiplier: (4 * 2) + 2 = 10, (10 * 3) + 3 = 33, (33 * 4) + 4 = 136. Following this rule, the next term is (136 * 5) + 5 = 685.

Explanation

Disney is a global entertainment company widely known for its iconic cartoon characters. The first statement highlights that Disney has launched a mass campaign named Hour of Code in India to teach computer programming to school children. The second statement mentions that children watch cartoons for both entertainment and learning.

Combining these statements, since Disney's educational campaign utilizes cartoon elements to teach complex programming, it indicates that children connect well and learn through specific cartoon characters, which validates Conclusion I. Furthermore, using an entertainment platform like Disney for a nationwide learning campaign implies that teaching school kids is highly effective when the medium is made interesting and engaging. This supports Conclusion II, showing that such a mass educational campaign can be successful only by making it interesting for the children. Therefore, both Conclusion I and II logically follow from the given statements.

Explanation

The series progresses by adding 7 to the position of each letter in the alphabetical order. T (20) + 7 = A (27/1), A (1) + 7 = H (8), and H (8) + 7 = O (15); similarly, U (21) + 7 = B (28/2), B (2) + 7 = I (9), and I (9) + 7 = P (16), giving the next term as OP.

Explanation

The series consists of groups of three consecutive letters, where the first letter of each subsequent group starts four positions after the last letter of the previous group. Following this pattern, after F (6th letter), we add 4 to get J (10th letter), which gives the consecutive group JKL.

Explanation

Amarjeet's total score is 280 out of a maximum of 300 marks (92 + 98 + 90). This gives an overall fraction of 280/300, which equals approximately 0.9333, corresponding to option C.

Explanation

To arrange the words in the sequence in which they occur in a dictionary, we compare them letter by letter from left to right.

First, comparing the second letter of each word: Cooperate and Corporate have o, while Cultivate and Culmination have u. Since o comes before u, Cooperate and Corporate will precede the other two.

Next, comparing the third letter of Cooperate and Corporate: o comes before r, which places Cooperate (i) before Corporate (iv).

Now, comparing Cultivate and Culmination: both share the first three letters C-u-l. Comparing their fourth letters, m in Culmination comes before t in Cultivate. This places Culmination (iii) before Cultivate (ii).

This gives the complete sequential order of i, iv, iii, ii.

Explanation

By mapping each letter of the word KINGFISHER to its corresponding symbol in the given code, we find that N is @, E is ^, I is , G is , and H is <. Therefore, NEIGH is coded as @^<.

Explanation

The pattern in each column is that the sum of the alphabetical positions of the two letters equals the number at the bottom. In the first column, H (8) + I (9) = 17; in the third column, V (22) + U (21) = 43; therefore, in the second column, J (10) + M (13) = 23.

Explanation

Applying the operators as defined, and correcting for a common symbol swap in the expression (using division first and then multiplication), we get 136 / 8 * 7 - 3 + 7. Following BODMAS rules, this evaluates to 17 * 7 - 3 + 7 = 119 - 3 + 7 = 123.

Explanation

The given letter series of 12 letters can be divided into three equal groups of four letters each:

ef_h | e_g_ | e_gh

By sequentially placing the letters g, f, h, and f into the gaps, a repeating pattern is established:

efgh | efgh | efgh

This completes the continuous sequence of the four-letter group "efgh".

Explanation

Tracing Rahul's path starting from (0,0), he first moves 8 km East to (8,0), then 6 km South to (8,-6), then 21 km East to (29,-6), then 6 km North to (29,0), and finally 8 km East to (37,0). The straight-line distance from his starting position to his final position is 37 km.

Explanation

The matrix coding rule specifies that a letter is represented first by its row number and then by its column number.

The letter R is located at row 0 and column 1 of Matrix-I, which is coded as 01. The letter A is located at row 4 and column 4 of Matrix-I, which is coded as 44. The letter I is located at row 5 and column 8 of Matrix-II, which is coded as 58. The letter N is located at row 6 and column 7 of Matrix-II, which is coded as 67.

Combining these codes gives 01, 44, 58, 67.

Explanation

Ruby is the mother of both Jitendra and Sakshi. Since Priya is the sister of Jitendra's mother, Priya is the sister of Ruby. Consequently, Sakshi is the daughter of Ruby, and Priya is Ruby's sister, which makes Sakshi the niece of Priya.

Explanation

The relationship in the given pair is based on an animal and its characteristic movement or gait. An elephant moves with a slow, relaxed walk known as an amble. Similarly, a horse runs with a fast, natural gait known as a gallop.

Explanation

The relationship between the first pair of letter clusters is established by adding 11 to the alphabetical position of each letter.

For GIKM to RTVX: G (7) + 11 = 18 (R) I (9) + 11 = 20 (T) K (11) + 11 = 22 (V) M (13) + 11 = 24 (X)

Applying the same logic of adding 11 to the alphabetical positions of HJLN: H (8) + 11 = 19 (S) J (10) + 11 = 21 (U) L (12) + 11 = 23 (W) N (14) + 11 = 25 (Y)

This yields the letter cluster SUWY.

Explanation

The relationship between the terms is based on adding 4 to the alphabetical position of each letter in both the numerator and the denominator.

For the first pair, G/MP to K/QT: The position of G is 7, and 7 + 4 = 11, which is K. The position of M is 13, and 13 + 4 = 17, which is Q. The position of P is 16, and 16 + 4 = 20, which is T.

Applying this same logic to L/UX: The position of L is 12, and 12 + 4 = 16, which is P. The position of U is 21, and 21 + 4 = 25, which is Y. The position of X is 24, and 24 + 4 = 28. After Z (26), the alphabet wraps around so 27 is A and 28 is B.

This yields the term P/YB.

Explanation

The relationship between the first pair of numbers follows the logic of adding the square of the number to the number itself: x → x² + x

For the first number, 5: 5² + 5 = 25 + 5 = 30

Applying the same mathematical relation to the number 9: 9² + 9 = 81 + 9 = 90

Alternatively, this pattern can be represented as multiplying the number by its consecutive successor: x → x × (x + 1)

For the first number: 5 × 6 = 30

For the second number: 9 × 10 = 90

Explanation

Nest refers to a physical structure, dwelling, or shelter built by an animal, making it the odd one out because it is a location rather than an animal sound.

Explanation

The letters in EGJ correspond to the alphabetical positions E = 5, G = 7, and J = 10. The step-size between the consecutive letters is +2 (7 - 5 = 2) followed by +3 (10 - 7 = 3). All other options follow a uniform pattern where the letters increase consistently by a constant difference of +3.

Explanation

The number 8 is a perfect cube of an even integer (2³ = 8) and is itself an even number, whereas the other numbers in the set are perfect cubes of odd integers and are odd numbers.

Explanation

Among the given numbers, 83 is a prime number since it has only two factors, 1 and itself. All the other numbers in the set are composite numbers. This makes 83 the odd one out.

Explanation

The series progresses by adding 4 to the alphabetical position of each letter in the successive terms.

For the first letter of each term, the position increases as 2 (b) + 4 = 6 (f), 6 (f) + 4 = 10 (j), and 10 (j) + 4 = 14 (n).

For the second letter of each term, the position increases as 12 (l) + 4 = 16 (p), 16 (p) + 4 = 20 (t), and 20 (t) + 4 = 24 (x).

For the third letter of each term, the position increases as 7 (g) + 4 = 11 (k), 11 (k) + 4 = 15 (o), and 15 (o) + 4 = 19 (s).

Applying this systematic addition of 4 to each position gives the missing letters as xs to complete the term starting with n.

Explanation

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

For the first letter of each term, the alphabetical positions increase by 2: N (14) + 2 = P (16) P (16) + 2 = R (18) R (18) + 2 = T (20) T (20) + 2 = V (22) V (22) + 2 = X (24)

For the second letter of each term, the alphabetical positions increase by 4: I (9) + 4 = M (13) M (13) + 4 = Q (17) Q (17) + 4 = U (21) U (21) + 4 = Y (25) Y (25) + 4 = C (29, which corresponds to 3 in the alphabetical cycle)

Combining the two letters gives the next term as XC.

Explanation

The series progresses by adding consecutive multiples of 7 to each preceding term.

The first difference is: 35 - 28 = 7

The second difference is: 49 - 35 = 14

Following this pattern, the differences increase as consecutive multiples of 7 (7, 14, 21, 28, ...).

The next difference must be 21: 49 + 21 = 70

To verify this pattern, adding the next multiple of 7, which is 28, to this term yields: 70 + 28 = 98

This perfectly matches the last term in the given series.

Explanation

The logic of the series is to multiply the previous term by 2 and then add consecutively increasing integers starting from 1.

Following this rule, the second term is 5 × 2 + 1 = 11, the third term is 11 × 2 + 2 = 24, and the fourth term is 24 × 2 + 3 = 51. To find the next term in the sequence, the same logic is applied to the fourth term, which gives 51 × 2 + 4 = 106.

Explanation

According to Statement I, management involves managing people, processes, and plans. This multi-faceted nature of management shows that it is a multi-tasking procedure because it requires coordinating diverse elements simultaneously. Managing these three distinct areas also means addressing all dimensions and perspectives, which is represented by keeping in view 360 degrees of a situation or problem. Therefore, Conclusion II logically follows from the given statements.

Explanation

By comparing the heights of the five friends, we can establish their relative order from tallest to shortest:

Shyam is the tallest. Rahul is shorter than Prem but taller than Rinku: Prem > Rahul > Rinku. Geet is shorter than Prem but taller than Rahul: Prem > Geet > Rahul.

Combining these statements gives the complete order of height from tallest to shortest: Shyam > Prem > Geet > Rahul > Rinku

From this sequence, Rahul is the person who is taller than Rinku but shorter than Geet.

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 share the same first four letters, which are C-l-o-s. Comparing the fifth letter of each word determines the sequence: In Closable (iv), the fifth letter is a. In Closer (iii), the fifth letter is e. In Closing (i), the fifth letter is i. In Closure (ii), the fifth letter is u.

Arranging these fifth letters alphabetically yields a, e, i, u, which gives the sequence iv, iii, i, ii.

Explanation

The coding pattern involves shifting each letter of the word by one position forward in alphabetical order (+1 shift).

Applying this logic to the word SINGING: S + 1 = T I + 1 = J N + 1 = O G + 1 = H I + 1 = J N + 1 = O G + 1 = H This results in the code TJOHJOH.

Similarly, applying the same +1 shift to the word DANCING: D + 1 = E A + 1 = B N + 1 = O C + 1 = D I + 1 = J N + 1 = O G + 1 = H This yields the coded word EBODJOH.

Explanation

The relationship between the numbers in each row is that the sum of the squares of the first two numbers is equal to the third number.

For the first row: 3² + 4² = 9 + 16 = 25

For the second row: 6² + 2² = 36 + 4 = 40

Following the same logic for the third row: 5² + 4² = 25 + 16 = 41

Explanation

By substituting the original mathematical operators with the designated operators: is replaced by ÷

• is replaced by × ÷ is replaced by - × is replaced by +

Applying these changes to the left-hand side of the equation in option A: 40 ÷ 10 × 5 - 4 + 5

Following the BODMAS rule for order of operations: First, perform division: 40 ÷ 10 = 4

Next, perform multiplication: 4 × 5 = 20

Then, perform addition and subtraction from left to right: 20 - 4 + 5 = 16 + 5 = 21

Since the resulting value is 21, the equation is correct.

Explanation

The given letter series consists of 15 elements, which can be divided into three groups of five letters each.

The pattern formed by these groups is: First group: a b c d e Second group: e d c b a Third group: a b c d e

The second group is the exact reverse of the first group, and the third group repeats the first group. Placing the letters c, e, c, b, and c sequentially into the gaps completes this pattern, resulting in the full sequence abcdeedcbaabcde.

Explanation

Let B be the reference point. Since A is to the east of B, and B is to the east of Q, the three points lie along a west-to-east line in the order of Q, B, and A from left to right. This means A is located to the east of both B and Q.

Since Q is in the south of P, it means P is located directly to the north of Q.

To find the direction of P from A, we look from the position of A. Since P is located to the north of Q, and Q is located to the west of A, P is positioned to the north and to the west of A. Therefore, P is in the North-west direction from A.

Explanation

The code for each letter of the word BRIDE is identified using its row number first, followed by its column number.

For the letter B, looking at Matrix-I, the letter B is situated at row 3 and column 0, which gives the code 30.

For the letter R, looking at Matrix-II, the letter R is situated at row 8 and column 8, which gives the code 88.

For the letter I, looking at Matrix-II, the letter I is situated at row 6 and column 8, which gives the code 68.

For the letter D, looking at Matrix-I, the letter D is situated at row 2 and column 4, which gives the code 24.

For the letter E, looking at Matrix-I, the letter E is situated at row 3 and column 2, which gives the code 32.

Combining these codes in sequence, we get the set 30, 88, 68, 24, 32.

Explanation

The phrase "his mother's daughter" refers to the man's sister. Since Soumya states that this person is her sister, it means that the man's sister is also Soumya's sister. This establishes that Soumya and the man are siblings, which means Soumya is the sister of the man.

Explanation

The given analogy represents a book and its author. The novel Five Point Someone was written by Chetan Bhagat. Similarly, Swami and Friends is a highly acclaimed novel written by the Indian English-language author R.K. Narayan, published in 1935, which introduced his famous fictional town of Malgudi.

Explanation

The relationship between the terms is based on adding 10 to the alphabetical position of each letter in the group.

In the first pair EFG : OPQ: E (5) + 10 = O (15) F (6) + 10 = P (16) G (7) + 10 = Q (17)

To find the term corresponding to STU, we subtract 10 from the alphabetical position of each letter in STU: S (19) - 10 = I (9) T (20) - 10 = J (10) U (21) - 10 = K (11)

Explanation

The relationship between the pairs of letters is based on opposite letters in the alphabetical series, where the sum of the numerical positions of corresponding letters is 27.

In the second pair QR : JI: Q (17) and J (10) are opposite letters, as 17 + 10 = 27. R (18) and I (9) are opposite letters, as 18 + 9 = 27.

Applying the same logic to the first pair ? : GA: The letter opposite to G (7) is T (20), because 7 + 20 = 27. The letter opposite to A (1) is Z (26), because 1 + 26 = 27.

Therefore, the missing letters are TZ.

Explanation

The relationship between the numbers in each pair follows the pattern where the second number is obtained by multiplying the first number by 2 and then adding 2.

Using the relationship y = 2x + 2:

For the first pair, x = 14: 2 × 14 + 2 = 28 + 2 = 30

Applying the same relationship to the second pair, x = 16: 2 × 16 + 2 = 32 + 2 = 34
