Explanation

To arrange words in dictionary order, they are compared letter by letter from left to right. All four words start with the letters P-e-a. The word Pea (3) ends after these three letters, making it the first in the sequence. For the remaining words, the fourth letter is compared: Peanut (4) has n, Pearl (1) has r, and Peasant (2) has s. In alphabetical order, n precedes r, and r precedes s. Therefore, the sequence follows the order of Peanut, then Pearl, and finally Peasant. This results in the arrangement 3, 4, 1, 2.

Explanation

The given series consists of 20 positions, which can be divided into four identical groups of five letters each to identify a repeating pattern. By placing the letters from the correct set into the gaps, the series is organized as follows:

g f e (i) i | g (f) e i i | (g) f e i (i) | g f (e) i i

This reveals a consistent five-letter block, g-f-e-i-i, that repeats four times. The letters required to complete the gaps are i at the 4th position, f at the 7th position, g at the 11th position, i at the 15th position, and e at the 18th position. Placing these letters sequentially results in the set i, f, g, i, e.

Explanation

The given series follows a pattern where each subsequent number is obtained by multiplying the previous number by an increasing integer sequence starting from 2.

The first term is 3. The second term is 3 × 2 = 6. The third term is 6 × 3 = 18. The fourth term is 18 × 4 = 72. The fifth term, which is the missing value, is calculated as 72 × 5 = 360.

To verify the pattern, the next term in the series is 360 × 6 = 2160, which matches the final number provided in the series.

Explanation

The speaker's husband's father is her father-in-law. The statement establishes that this individual is also Mohan's grandfather. The introduced lady is described as the only daughter of this father-in-law. The sister of one's husband is categorized as a sister-in-law. Since the introduced lady is the sister of the speaker's husband, the speaker relates herself to the introduced lady as a sister-in-law.

Explanation

Let Aadhya's present age be A and her son's present age be S. According to the first condition, two years ago Aadhya was three times as old as her son, which gives the equation A - 2 = 3(S - 2). Simplifying this, we get A - 3S = -4, or A = 3S - 4.

According to the second condition, two years hence twice her age will be equal to five times that of her son, which gives the equation 2(A + 2) = 5(S + 2). Substituting the value of A from the first equation into the second:

2(3S - 4 + 2) = 5S + 10 2(3S - 2) = 5S + 10 6S - 4 = 5S + 10 S = 14

Now, substitute S = 14 back into the expression for Aadhya's age: A = 3(14) - 4 A = 42 - 4 A = 38

Explanation

The word SITUATION requires the letter U for its formation. However, the given word ADMINISTRATION contains only the letters A, D, M, I, N, I, S, T, R, A, T, I, O, and N. Since the letter U is not present in the base word ADMINISTRATION, the word SITUATION cannot be formed using the provided letters.

Explanation

The coding pattern involves shifting each letter of the word two positions backward in the English alphabetical sequence. This can be expressed by the relation L_c = Lₒ - 2, where Lₒ represents the original letter's numerical position and L_c represents the coded letter's position.

In the word MOTHER: M (13) - 2 = K (11) O (15) - 2 = M (13) T (20) - 2 = R (18) H (8) - 2 = F (6) E (5) - 2 = C (3) R (18) - 2 = P (16)

Applying the same logic to the word HOUSE: H (8) - 2 = F (6) O (15) - 2 = M (13) U (21) - 2 = S (19) S (19) - 2 = Q (17) E (5) - 2 = C (3)

By subtracting 2 from the position of each letter in HOUSE, we obtain the sequence of letters F, M, S, Q, and C, which forms the code FMSQC.

Explanation

Substitute the given symbols with their respective mathematical operators: D is multiplication (×), S is addition (+), M is division (÷), and A is subtraction (-). The expression 28D6S34M2A8D6 converts to:

28 × 6 + 34 ÷ 2 - 8 × 6

Applying the BODMAS rule, perform division first: 34 ÷ 2 = 17 The expression becomes 28 × 6 + 17 - 8 × 6.

Next, perform the multiplication operations: 28 × 6 = 168 8 × 6 = 48 The expression becomes 168 + 17 - 48.

Now, perform addition: 168 + 17 = 185

Finally, perform subtraction: 185 - 48 = 137

Explanation

The numerical sequence follows a specific logical pattern defined by the formula a b = 2a + b. In the first instance, substituting a = 3 and b = 4 into the formula results in 2(3) + 4 = 6 + 4 = 10. Applying the same logic to the second instance where a = 5 and b = 8, the calculation is 2(5) + 8 = 10 + 8 = 18. To find the value for 7 7, the values a = 7 and b = 7 are used in the same pattern, leading to 2(7) + 7 = 14 + 7 = 21.

Explanation

The numerical logic in this matrix is based on column-wise operations. In each column, the third element is derived by subtracting the square of the first element from the square of the second element. The general formula for each column is C₃ = (C₂)² - (C₁)².

Applying this logic to the first column: 11² - 1² = 121 - 1 = 120

Applying this logic to the second column: 7² - 2² = 49 - 4 = 45

Applying this logic to the third column to find the missing value: 5² - 3² = 25 - 9 = 16

Explanation

Rahul's path can be traced using a coordinate system starting at the origin (0, 0). He first walks South for an unspecified distance y₁, reaching the point (0, -y₁). Turning right while facing South means he moves towards the West; walking 5 km in this direction places him at (-5, -y₁). From there, he turns left, which directs him South again; walking 3 km results in the coordinates (-5, -y₁ - 3). His final move is a left turn from the South-facing direction, which turns him East; walking 5 km East brings his position to (0, -y₁ - 3). Because his final x-coordinate is zero and his y-coordinate is a negative value, he is located directly South of his original starting point.

Explanation

In logical reasoning, conclusions must be directly supported by the provided premises without incorporating external assumptions or subjective beliefs. The statements establish facts regarding the socioeconomic status of Odisha, specifically its underdevelopment and the persistence of poverty, unemployment, and illiteracy.

Conclusion I introduces a specific cause for these conditions—the sensitivity of the administration—which is not mentioned or implied in the statements. Underdevelopment can result from a variety of complex factors such as historical context, geographical challenges, or resource allocation, and the statements provide no data to isolate the administration's role. Conclusion II attributes the state's condition to a supernatural or fatalistic cause, which is a matter of personal belief and cannot be logically deduced from statistical or socioeconomic facts. Therefore, neither conclusion logically follows from the given information.

Explanation

The relationship in the given pair is that of a commodity and its designated storage facility. Grain is collected and stored in a warehouse for future distribution and use. In the same way, water is collected and stored behind a dam in a reservoir to regulate its flow and ensure its availability for irrigation, human consumption, or industrial purposes.

Explanation

The relationship in the first pair ADFG : KNPQ is established through a consistent alphabetical shift and an internal gap pattern. Each letter in the first group is shifted forward by 10 positions to create the second group: A(1) + 10 = K(11), D(4) + 10 = N(14), F(6) + 10 = P(16), and G(7) + 10 = Q(17). Furthermore, the internal structure of these letter groups follows a sequence of increments where the gaps between letters are +3, +2, and +1 respectively. In ADFG, the positions are 1 (+3) 4 (+2) 6 (+1) 7. In KNPQ, the positions are 11 (+3) 14 (+2) 16 (+1) 17. Applying this same internal pattern of +3, +2, and +1 to the options, the sequence NQST is the only one that fits the logic: N(14) + 3 = Q(17), Q(17) + 2 = S(19), and S(19) + 1 = T(20).

Explanation

The logic followed in the given pair is x : x², where the second number is the square of the first number. In the provided analogy, 12² = 144. Applying the same mathematical relationship to the selected option, the square of 20 is 20 × 20 = 400, which satisfies the pattern established in the question.

Explanation

A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean or a lake. Unlike the other features which are specific types of landforms or land masses defined by their relationship to water, a bay is a geographic feature defined as a body of water partially surrounded by land. Peninsula, Island, and Cape all represent various physical land structures, making the water-based nature of a bay the distinguishing characteristic in this group.

Explanation

Tomato is the odd one out because it grows above the ground on the plant stems. The other three items are modified roots or tubers that develop and are harvested from beneath the soil surface.

Explanation

The pair 41 - 72 is the odd one out because the sum of the digits of the first number is not equal to the sum of the digits of the second number. In this pair, the digit sum for 41 is 4 + 1 = 5, and the digit sum for 72 is 7 + 2 = 9. Since 5 ≠ 9, the pair does not satisfy the property of digit sum equality between its components.

Explanation

Words in a dictionary are arranged in alphabetical order by comparing each character from left to right. All the given words start with the prefix Im. Comparing the third letter of each word, the letter m comes before the letter p, meaning Immigrate and Immutable occupy the first two positions in the list. To determine the order of the remaining words starting with Imp, the fourth letter is compared. Impassioned has the letter a in the fourth position, while Imperative has the letter e. Since a precedes e in the alphabet, Impassioned follows the two Imm words and precedes Imperative. This sequence places Impassioned as the third word in the dictionary order.

Explanation

The series is formed by adding an increasing sequence of integers to the alphabetical position of each letter. In the English alphabet, the positions are B = 2, F = 6, K = 11, and Q = 17. The transition from B to F involves an addition of 6 - 2 = 4. The transition from F to K involves an addition of 11 - 6 = 5. The transition from K to Q involves an addition of 17 - 11 = 6. The values being added follow the sequence 4, 5, 6, which indicates that the next value to be added should be 7. Calculating the position of the missing term gives 17 + 7 = 24. The letter corresponding to the 24th position is X.

Explanation

The given sequence follows the pattern of an arithmetic progression where each term is obtained by adding a constant common difference to the previous term. Calculating the differences between the consecutive terms: 9 - 5 = 4 13 - 9 = 4 17 - 13 = 4

The common difference is d = 4. Following this pattern, the missing term is calculated by adding 4 to the fourth term: 17 + 4 = 21

To verify the pattern, adding 4 to 21 yields 21 + 4 = 25, which matches the final term of the series.

Explanation

The phrase all but eight died is a linguistic construction meaning that every sheep died except for eight of them. In this context, the word but functions as a preposition meaning except. Therefore, out of the original 17 sheep, 9 sheep died and 8 sheep survived. Since the question asks how many sheep the shepherd was left with, the answer is the number of survivors, which is 8.

Explanation

Let the present age of the son be s and the father be f. The problem states that the sum of their present ages is f + s = 60, which can be rewritten as f = 60 - s. Six years ago, the father's age was f - 6 and the son's age was s - 6. According to the problem, at that time the father was five times as old as the son, so f - 6 = 5(s - 6).

Substituting the expression for f into this equation gives (60 - s) - 6 = 5s - 30. Simplifying the left side results in 54 - s = 5s - 30. Adding s to both sides and adding 30 to both sides yields 84 = 6s. Dividing by 6, we find the son's present age s = 14 years. The question asks for the son's age after 6 years, which is 14 + 6 = 20 years.

Explanation

The word AMBITION cannot be formed because it contains the letter B, which is not present in the word EXAMINATION. While all other letters required for AMBITION are available in the base word, the absence of the letter B makes it impossible to construct this specific alternative.

Explanation

The coding logic involves dividing the six-letter word into two equal halves and applying a specific shift to each half. For the word AMOUNT, the first three letters A, M, and O are shifted forward by one position in the alphabetical order to become B, N, and P respectively. The last three letters U, N, and T are shifted backward by one position to become T, M, and S respectively.

Applying this same pattern to AROUND, we split the word into ARO and UND. Shifting the first half A-R-O forward by one position gives B-S-P. Shifting the second half U-N-D backward by one position gives T-M-C. Combining these results yields the code BSPTMC.

Explanation

The logic follows a specific rearrangement of the digits in each expression. If we represent the input digits as A × B × C, the resulting number is formed by the sequence B C A. In the first example, 5 × 4 × 0 yields 405, where the second digit 4 moves to the first position, the third digit 0 moves to the second position, and the first digit 5 moves to the third position. In the second example, 3 × 2 × 8 results in 283, following the same B C A pattern (2, 8, 3). Applying this rule to 1 × 7 × 6, where A=1, B=7, and C=6, the digits are rearranged into the sequence 761.

Explanation

The pattern followed in the given equations is the difference between the sum of the digits of the first number and the sum of the digits of the second number.

For 56 × 11 = 9: Sum of digits of 56 = 5 + 6 = 11 Sum of digits of 11 = 1 + 1 = 2 Difference = 11 - 2 = 9

For 37 × 13 = 6: Sum of digits of 37 = 3 + 7 = 10 Sum of digits of 13 = 1 + 3 = 4 Difference = 10 - 4 = 6

For 42 × 12 = 3: Sum of digits of 42 = 4 + 2 = 6 Sum of digits of 12 = 1 + 2 = 3 Difference = 6 - 3 = 3

Following the same logic for 87 × 77: Sum of digits of 87 = 8 + 7 = 15 Sum of digits of 77 = 7 + 7 = 14 Difference = 15 - 14 = 1

Explanation

Vijay moves West, turns left to face South, and turns left again to face East. A 45-degree right turn from the East direction points him toward the South-East.

Explanation

The statement All that glitters is not gold is a logical negation of the proposition that all glittering things are gold. It implies that some things which glitter are not made of gold. This premise provides information about the set of glittering objects but does not establish a universal rule regarding the properties of gold itself. Specifically, the statements do not define whether gold must glitter or must not glitter. Statement II identifies Sujatha's ornament as gold, but because the premises lack a link between the substance gold and the physical property of glittering, there is no sufficient evidence to determine the visual characteristics of her ornament. Consequently, neither the conclusion that the ornament glitters nor the conclusion that it does not glitter can be logically deduced.

Explanation

The relationship in the first pair is that of a treatment and the condition it addresses. A disease is cured through medical treatment or intervention. Similarly, in the second pair, the process of healing is specifically used to describe the restoration of physical damage, such as a wound or an injury, back to a healthy state. Therefore, just as a doctor cures a disease, the body or a physician heals an injury.

Explanation

The relationship follows the alphabetical positional shift L₂ = L₁ + 13, where L represents the position of the letter in the English alphabet. For the first pair, the letters shift as D(4) → 17(Q), B(2) → 15(O), C(3) → 16(P), and E(5) → 18(R). Applying the same transformation to the second pair gives J(10) + 13 = 23 (W), L(12) + 13 = 25 (Y), K(11) + 13 = 24 (X), and I(9) + 13 = 22 (V).

Explanation

The logic followed in this numerical analogy is a constant multiplication factor. In the first pair, the relationship is established by the formula y = x × 7. Substituting the first number, we get 6 × 7 = 42. Applying the same logic to the second part of the analogy, we multiply the given number 12 by the same factor: 12 × 7 = 84.

Explanation

The pair High-Up consists of words that are synonyms or convey a similar directional meaning. In the remaining pairs, the words are antonyms: Past is the opposite of Present, Often is the opposite of Seldom, and Fresh is the opposite of Stale. Therefore, High-Up is the odd pair because it lacks the relationship of opposition found in the others.

Explanation

The set ALO includes the letter L, which is a consonant. All other provided letter groups consist exclusively of vowels from the English alphabet (A, E, I, O, and U). The inclusion of a consonant distinguishes this group from the rest of the alternatives.

Explanation

The number 87 is a composite number because it is divisible by factors other than 1 and itself. Applying the divisibility rule for 3, the sum of its digits is 8 + 7 = 15. Since 15 is a multiple of 3, the number 87 is divisible by 3, yielding the factors 3 × 29. This characteristic of being composite distinguishes it from the other values in the set.

Explanation

To determine the dictionary order, words are compared letter by letter from left to right. All four words begin with the prefix Te. Comparing the third letters, Temple and Temperature both have m, while Tenant has n and Terminate has r. Since m precedes n and r in the alphabet, either Temple or Temperature must come first. Between Temple and Temperature, the first four letters Temp are identical. Comparing the fifth letters, Temperature has e while Temple has l. Since e comes before l in alphabetical order, Temperature is the word that appears first in the dictionary.

Explanation

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

For the first letter of each triplet: N (14) +3 Q (17) +3 T (20) +3 W (23). For the second letter of each triplet: O (15) +3 R (18) +3 U (21) +3 X (24). For the third letter of each triplet: M (13) +3 P (16) +3 S (19) +3 V (22).

By applying this +3 increment to each position of the last given term TUS, the next term is determined to be WXV.

Explanation

The given sequence follows a pattern where the difference between consecutive terms increases by 2. Calculating the differences between the terms: 3 - 1 = 2 7 - 3 = 4 13 - 7 = 6 21 - 13 = 8 The differences form a sequence of consecutive even numbers: 2, 4, 6, 8. Following this logic, the next difference in the series must be 8 + 2 = 10. To find the missing term, add this difference to the last given term: 21 + 10 = 31.

Explanation

September has 30 days. To find the day on 27th October, we calculate the total number of days elapsed from 27th September. There are 3 days remaining in September (30 - 27) and 27 days in October. The total number of days is 3 + 27 = 30 days.

To determine the day of the week, we find the number of odd days by dividing the total days by 7: 30 ÷ 7 = 4 weeks and 2 odd days. Counting 2 days forward from Saturday results in Monday.

Explanation

The relationship in the analogy is based on the national symbol of the respective countries. The Peacock is the national bird of India. Similarly, the Bear is the national animal and a long-standing symbol of Russia, frequently used as a national personification for the country in cultural and political contexts.

Explanation

Let the current ages of the man and his wife be 4x and 3x. After 4 years, their ages will be 4x + 4 and 3x + 4. According to the given ratio:

(4x + 4)/(3x + 4) = ⁹⁄₇

Cross-multiplying the terms: 7(4x + 4) = 9(3x + 4) 28x + 28 = 27x + 36 x = 8

The man's current age is 4 × 8 = 32 years, and the wife's current age is 3 × 8 = 24 years.

Let the marriage have taken place n years ago. At that time, their ages were 32 - n and 24 - n. The ratio of their ages at marriage was 5:3:

(32 - n)/(24 - n) = ⁵⁄₃

Cross-multiplying the terms: 3(32 - n) = 5(24 - n) 96 - 3n = 120 - 5n 2n = 24 n = 12

Therefore, the man and his wife were married 12 years ago.

Explanation

The word NATIONAL cannot be formed from the letters in ALTERNATIVES because it requires the letter O, which is not present in the source word. Furthermore, NATIONAL contains two instances of the letter N, while ALTERNATIVES provides only one N. Since the necessary characters and their required frequencies are not available, the word cannot be constructed.

Explanation

The code for the string ZLTPXM is determined by substituting each individual letter with its specific numerical value provided in the instructions. Following the given mapping, Z corresponds to 8, L corresponds to 2, T corresponds to 1, P corresponds to 7, X corresponds to 9, and M corresponds to 5. Placing these digits in the exact order of the letters in the required sequence yields 821795.

Explanation

The numerical logic applied in the given equations involves finding the actual product of the two numbers and then reversing the order of its digits. In the first case, the multiplication of 24 and 2 yields 24 × 2 = 48. Reversing the digits of 48 results in 84. Similarly, in the second case, the multiplication of 32 and 3 yields 32 × 3 = 96. Reversing the digits of 96 results in 69. Following this same pattern for the third expression, we first calculate the product of 13 and 3, which is 13 × 3 = 39. Reversing the digits of 39 gives the final value of 93.

Explanation

By substituting the mathematical symbols according to the logic of the problem, we establish the following mapping:

• becomes ÷ (division) becomes × (multiplication) X and x both become + (addition) ÷ becomes - (subtraction)

To determine which statement is false, we evaluate option c: (10 X 7) - 2 < (10 - 2) x 7

Substituting the symbols in the Left-Hand Side (LHS): (10 + 7) × 2 = 17 × 2 = 34

Substituting the symbols in the Right-Hand Side (RHS): (10 × 2) + 7 = 20 + 7 = 27

The resulting inequality is 34 < 27. Since 34 is greater than 27, this statement is false.

Explanation

Ram starts at a point and travels 20 meters North. By then turning East and walking 5 meters, he creates a perpendicular displacement from his original line of travel. His final turn to the right means he is now facing South; walking 20 meters in this direction brings him back to the same horizontal level as his starting point because the Northward and Southward distances are identical. This movement pattern forms three sides of a rectangle, where the two 20-meter legs are parallel and the 5-meter Eastward leg represents the width. Consequently, the distance from his starting point to his finishing point is equal to the length of that Eastward segment, which is 5 meters.

Explanation

The given statements can be represented using set notation where G represents goats, T represents tigers, and L represents lions. The first statement, All goats are tigers, implies G ⊆ T. The second statement, All tigers are lions, implies T ⊆ L. By the transitive property of subsets, if G ⊆ T and T ⊆ L, then G ⊆ L, meaning all goats are lions.

Conclusion I and II are the converses of the original statements. In categorical logic, a universal affirmative statement of the form All A are B does not imply that All B are A. Therefore, we cannot conclude that all tigers are goats or all lions are tigers. Conclusions III and IV are universal negative statements. Since we have established that the set of goats is a subset of the set of lions (G ⊆ L), there is at least a partial overlap between goats and lions, assuming the sets are not empty. This directly contradicts the claims that No goat is a lion or No lion is a goat. Consequently, none of the provided conclusions logically follow from the premises.

Explanation

The pattern in the analogy follows a constant shift of +4 for each letter's position in the English alphabet. For the first pair, BDCE relates to FHGI as follows: B(2)+4=6(F), D(4)+4=8(H), C(3)+4=7(G), and E(5)+4=9(I). Applying this same +4 transformation to the letters in RTSU: R(18) + 4 = 22 (V) T(20) + 4 = 24 (X) S(19) + 4 = 23 (W) U(21) + 4 = 25 (Y)

Explanation

The relationship between the numbers in the first pair is established by dividing the first number by 2 and then adding 2 to the quotient to obtain the second number.

For the first pair 6 : 5: (6 ÷ 2) + 2 = 3 + 2 = 5

Following the same logic for the second pair 8 : ?: (8 ÷ 2) + 2 = 4 + 2 = 6

Explanation

The Moon is classified as a natural satellite because it orbits a planet, specifically the Earth. Conversely, Mars, Venus, and Jupiter are all categorized as planets, which are celestial bodies that orbit a star, in this case, the Sun. Therefore, the Moon is the odd term based on its astronomical status as a satellite rather than a planet.
