Explanation

By interchanging the signs ÷ and - (represented as + and -), the given equation is: 46 + 28 × 2 ÷ 7 - 13 = 41

According to the BODMAS rule, perform the division and multiplication first: 28 × 2 ÷ 7 = 56 ÷ 7 = 8

Now, substitute this value back into the equation and solve: 46 + 8 - 13 = 54 - 13 = 41

Since the left-hand side equals 41, the equation becomes correct.

Explanation

The correct logical and meaningful order of the given body parts is from top to bottom (head to toe) of the human body.

Eyes (1) are located at the highest position on the face. Lips (2) are situated below the eyes. Neck (4) is located below the head, connecting it to the torso. Stomach (3) is in the abdomen, which is below the neck. Legs (5) are at the bottom-most part of the body.

This anatomical arrangement from top to bottom gives the sequence 1, 2, 4, 3, 5.

Explanation

The relationship between the letter pairs is based on a cross-increment of +1.

In the first pair SH to IT: The second letter H is incremented by 1 to get the first letter of the next pair, which is I (H + 1 = I). The first letter S is incremented by 1 to get the second letter of the next pair, which is T (S + 1 = T).

Applying this same logic to the pair LM: The second letter M is incremented by 1 to get the first letter of the next pair, which is N (M + 1 = N). The first letter L is incremented by 1 to get the second letter of the next pair, which is M (L + 1 = M).

This yields the related letters NM.

Explanation

The relation between the three numbers in each set is defined by the formula:

|First number - Third number| = Second number

For the first given set (141, 13, 128): |141 - 128| = 13

For the second given set (238, 164, 402): |238 - 402| = 164

Applying the same mathematical relation to the set (48, 31, 79): |48 - 79| = 31

Explanation

The numbers in each set form an arithmetic progression where the difference between consecutive terms is constant.

In the first set (80, 72, 64): 80 - 72 = 8 72 - 64 = 8

In the second set (64, 56, 48): 64 - 56 = 8 56 - 48 = 8

In the set (63, 56, 49): 63 - 56 = 7 56 - 49 = 7

In all cases, the middle number is the arithmetic mean of the first and third numbers: (63 + 49) ÷ 2 = 56.

Explanation

To arrange the words in dictionary order, compare them letter by letter from left to right. All five words share the common starting letters Mor. Comparing the fourth letter of each word determines their sequence:

Moral and Morale both have a as their fourth letter. Since Moral is shorter, it comes first, followed by Morale.

Morbid has b as its fourth letter, placing it third.

More has e as its fourth letter, placing it fourth.

Morning has n as its fourth letter, placing it fifth.

Comparing these letters in alphabetical order gives the sequence Moral, Morale, Morbid, More, and Morning.

Explanation

The coding scheme alternates between the standard alphabetical position of the letter for odd-positioned letters (1st, 3rd, 5th, and 7th letters) and the reverse alphabetical position (calculated as 27 minus the standard position) for even-positioned letters (2nd, 4th, 6th, and 8th letters).

Applying this rule to the word PAYMENTS: P (1st, normal position) = 16 A (2nd, reverse position) = 27 - 1 = 26 Y (3rd, normal position) = 25 M (4th, reverse position) = 27 - 13 = 14 E (5th, normal position) = 5 N (6th, reverse position) = 27 - 14 = 13 T (7th, normal position) = 20 S (8th, reverse position) = 27 - 19 = 8

Combining these individual values side-by-side yields the code 16262514513208.

Explanation

To determine which equation becomes correct after interchanging the signs × and -, we apply the BODMAS rule to both equations.

For Equation I: 11 + 6 - 8 × 8 ÷ 2 Applying division first: 8 ÷ 2 = 4 Next, applying multiplication: 8 × 4 = 32 Finally, performing addition and subtraction: 11 + 6 - 32 = 17 - 32 = -15 Since -15 is not equal to 15, Equation I is incorrect.

For Equation II: 15 × 4 - 3 + 6 ÷ 1 Applying division first: 6 ÷ 1 = 6 Next, applying multiplication: 15 × 4 = 60 Finally, performing addition and subtraction: 60 - 3 + 6 = 63 Since 63 is equal to 63, Equation II is correct.

Explanation

The positional values of the letters in RTW are 18, 20, and 23. The differences between these consecutive letters are +2 and +3. This deviates from the consistent pattern of +3 between consecutive letters found in the other groups.

Explanation

The relationship in the first pair is between an animal and its dwelling place, where a lion lives in a den. Following the same logic, a web is the dwelling place of a spider.

Explanation

The relationship between the numbers in each set is defined by the formula: 2 × (Second number - First number) = Third number

Applying this formula to the first given set (286, 456, 340): 2 × (456 - 286) = 2 × 170 = 340

Applying this formula to the second given set (347, 592, 490): 2 × (592 - 347) = 2 × 245 = 490

Following the same logic for the set in Option C (198, 279, 162): 2 × (279 - 198) = 2 × 81 = 162

Explanation

According to Statement II, no blue is green. Because the negative relationship between two terms is mutually reciprocal, if no blue is green, then it is absolutely certain that no green is blue. This validates Conclusion I.

According to Statement I, some jungle are green. Because the existential relationship of some is also mutually reciprocal, if some jungle are green, then it must be true that some green are jungle. This validates Conclusion II.

Explanation

In the given set (413, 662, 911), the difference between consecutive numbers is constant:

662 - 413 = 249 911 - 662 = 249

Applying the same logic to the set (287, 536, 785):

536 - 287 = 249 785 - 536 = 249

Both sets follow the pattern of adding 249 to the preceding number to obtain the next number.

Explanation

Since H is the brother of I and G is the brother of H, all three (G, H, and I) are siblings. Since I is the son of J, J must be the parent of all three siblings G, H, and I. Furthermore, J is the sister of K, which means J is female. Therefore, J is the mother of G.

Explanation

The series follows a specific alphabetical progression for each letter position in the terms.

For the first letter of each term, the alphabetical position increases by 3: O (15) + 3 = R (18) R (18) + 3 = U (21) U (21) + 3 = X (24) X (24) + 3 = 27, which corresponds to A (27 - 26 = 1)

For the second letter of each term, the alphabetical position decreases by 7: L (12) - 7 = E (5) E (5) - 7 = -2, which corresponds to X (26 - 2 = 24) X (24) - 7 = Q (17) Q (17) - 7 = J (10)

For the third letter of each term, the alphabetical position increases by 8: R (18) + 8 = Z (26) Z (26) + 8 = 34, which corresponds to H (34 - 26 = 8) H (8) + 8 = P (16) P (16) + 8 = X (24)

Combining these letters gives AJX.

Explanation

The relationship in the given sets is that each subsequent number is obtained by multiplying the previous number by 3.

For the first set: 17 × 3 = 51 51 × 3 = 153

For the second set: 32 × 3 = 96 96 × 3 = 288

Applying the same logic to the numbers in option D: 42 × 3 = 126 126 × 3 = 378

Explanation

The operator A represents the multiplication operation between the two numbers.

Using the defined operation: 8 A 7 = 8 × 7 = 56 9 A 11 = 9 × 11 = 99

Applying this same relationship to the target expression: 16 A 15 = 16 × 15 = 240

Explanation

The coding pattern involves reversing the order of the letters in the word and then shifting each letter forward by two positions in the alphabetical order.

For the word DECENT, reversing the letters gives TNECED. Shifting each letter forward by two positions: T + 2 = V N + 2 = P E + 2 = G C + 2 = E E + 2 = G D + 2 = F This yields the code VPGEGF.

Applying this same logic to the word ENERGY, reversing the letters gives YGRENE. Shifting each letter forward by two positions: Y + 2 = A (wrapping around the alphabet) G + 2 = I R + 2 = T E + 2 = G N + 2 = P E + 2 = G This yields the code AITGPG.

Explanation

Pedology is the scientific study of soils, including their formation, chemistry, morphology, and classification. The study of fishes is known as ichthyology. Therefore, this pair represents an incorrect association, making it the odd one out among the given alternatives.

Explanation

The given sequence progress by adding consecutive natural numbers starting from 2 to each subsequent term:

The second term is 2 + 2 = 4. The third term is 4 + 3 = 7. The fourth term is 7 + 4 = 11. The fifth term is 11 + 5 = 16.

Following this constant increment in the difference between consecutive terms, the next number in the series is obtained by adding 6 to the fifth term:

16 + 6 = 22.

Explanation

The relationship between the numbers in each pair is defined by the formula: Second number = First number × 16

For the first pair: 8 × 16 = 128

For the third pair: 16 × 16 = 256

Applying the same logic to find the missing first number in the second pair: First number × 16 = 176 First number = 176 ÷ 16 = 11

Explanation

The first statement, Some A are T, establishes that there is a common intersection between set A and set T. This directly contradicts Conclusion I, No T is A, because if some A are T, then some T must also be A.

The second statement, Some T are H, establishes that there is a common intersection between set T and set H. This directly contradicts Conclusion II, No H is T, because if some T are H, then some H must also be T.

For Conclusion III, No A is H, both of the given statements are particular affirmative propositions. No definite relationship can be established between the terms A and H since they are linked only through the middle term T, and both statements are particular. Therefore, the negative statement No A is H does not logically follow.

Since all three conclusions fail to logically follow from the given statements, the correct assessment is that neither conclusion follows.

Explanation

In the given number pairs, the logic is that the first number is divided by 5 to obtain the second number. For the pair 38515 - 7701, dividing the first number by 5 gives 38515 ÷ 5 = 7703, which does not equal 7701. Therefore, this pair does not follow the common pattern.

Explanation

Each letter in the four-letter words follows a specific subtraction pattern based on alphabetical positions (A = 1, B = 2, ..., Z = 26).

For the first letter, the positions decrease by 7: T (20) - 7 = M (13), M (13) - 7 = F (6), F (6) - 7 = Y (25), and Y (25) - 7 = R (18).

For the second letter, the positions decrease by 5: R (18) - 5 = M (13), M (13) - 5 = H (8), H (8) - 5 = C (3), and C (3) - 5 = X (24).

For the third letter, the positions decrease by 9: A (1 or 27) - 9 = R (18), R (18) - 9 = I (9), I (9) - 9 = Z (26), and Z (26) - 9 = Q (17).

For the fourth letter, the positions decrease by 11: P (16) - 11 = E (5), E (5 or 31) - 11 = T (20), T (20) - 11 = I (9), and I (9 or 35) - 11 = X (24).

Combining these results, the next term in the series is RXQX.

Explanation

The given sequence is an arithmetic progression where each subsequent term is obtained by adding a constant difference of 37 to the preceding term.

The common difference is: 71 - 34 = 37 108 - 71 = 37

Adding 37 to the fourth term to find the missing fifth term: 145 + 37 = 182

Verifying with the next term: 182 + 37 = 219

Explanation

A rectangle is a geometric shape that consists of four sides. The relationship represents a polygon paired with its corresponding number of sides.

Explanation

By breaking down the statement, Rinku's son's sister is Rinku's daughter. The mother of Rinku's daughter is Rinku's wife. Therefore, the lady in the photograph is Rinku's wife.

Explanation

The letter-group KLIO follows the positional shift pattern of +1, -3, and +6 from one letter to the next. The other letter-groups follow a consistent pattern of +1, -3, and +4, making KLIO the deviation.

Explanation

The relationship between the letter pairs is based on adding 2 to the alphabetical position of each letter.

For the first pair, PM to RO: P is the 16th letter, and 16 + 2 = 18, which is R. M is the 13th letter, and 13 + 2 = 15, which is O.

Applying this same logic to the second pair, BC: B is the 2nd letter, and 2 + 2 = 4, which is D. C is the 3rd letter, and 3 + 2 = 5, which is E.

Thus, BC becomes DE.

Explanation

The original expression is: 10 × 8 + 6 ÷ 2 - 4

Interchanging the signs + and -, and the numbers 4 and 8, the expression becomes: 10 × 4 - 6 ÷ 2 + 8

Applying the BODMAS rule, perform division first: 6 ÷ 2 = 3

Next, perform the multiplication: 10 × 4 = 40

Now, solve the remaining addition and subtraction from left to right: 40 - 3 + 8 = 37 + 8 = 45

Explanation

The coding pattern represents the sum of the number of letters in the two given words.

For ONLINE + THEIR: Number of letters in ONLINE = 6 Number of letters in THEIR = 5 Sum = 6 + 5 = 11

For FREE + NEW: Number of letters in FREE = 4 Number of letters in NEW = 3 Sum = 4 + 3 = 7

Applying the same logic to HELP + STUDENTS: Number of letters in HELP = 4 Number of letters in STUDENTS = 8 Sum = 4 + 8 = 12

Explanation

Let the numbers in the set be represented as a, b, and c. The relationship between the numbers is: c = a + b + (b ÷ 2)²

Applying this logic to the set (79, 18, 178): a = 79, b = 18 c = 79 + 18 + (18 ÷ 2)² c = 97 + 9² c = 97 + 81 c = 178

Explanation

To find the logic behind the code, we divide the word into two equal halves of 3 letters each and analyze the shifts.

For PRINTS coded as QRLHQQ:

First half: PRI is coded as QRL. P (16) → Q (17) [Shift = +1] R (18) → R (18) [Shift = 0] I (9) → L (12) [Shift = +3] The differences between consecutive shifts are: 0 - 1 = -1 3 - 0 = +3

Second half: NTS is coded as HQQ. N (14) → H (8) [Shift = -6] T (20) → Q (17) [Shift = -3] S (19) → Q (17) [Shift = -2] The differences between consecutive shifts are: -3 - (-6) = +3 -2 - (-3) = +1

Now, applying this structural symmetry to STRICT:

First half: STR is coded as RAG. S (19) → R (18) [Shift = -1] T (20) → A (27) [Shift = +7] R (18) → G (7) [Shift = -11] The differences between consecutive shifts are: 7 - (-1) = +8 -11 - 7 = -18

Second half: ICT is coded as QSR. I (9) → Q (17) [Shift = +8] C (3) → S (19) [Shift = +16] T (20) → R (18) [Shift = -2] The differences between consecutive shifts are: 16 - 8 = +8 -2 - 16 = -18

Both halves of the word STRICT have the identical difference sequence of [+8, -18] in their letter shifts, confirming RAGQSR as the correct code.

Explanation

The general relation followed by the conforming pairs is: y = x² × (x + 1)

where x represents the number on the left and y represents the number on the right.

For the pair 13 - 2368, substituting x = 13 into this formula gives: 13² × (13 + 1) = 169 × 14 = 2366

Since 2366 is not equal to 2368, this pair does not follow the established rule.

Explanation

The symbols @ and # represent the mathematical operations of addition (+) and subtraction (-) respectively.

Applying this representation to the given equations: 13 @ 2 # 5 = 13 + 2 - 5 = 15 - 5 = 10 43 # 9 @ 16 = 43 - 9 + 16 = 34 + 16 = 50

Following the same logic for the required expression: 8 @ 6 # 3 = 8 + 6 - 3 = 14 - 3 = 11

Explanation

The given relationship is State : Capital, as Lucknow is the capital of Uttar Pradesh. Following the same logic, Kolkata is the capital of West Bengal, making it the correct matching pair.

Explanation

Karachi is the largest city and financial capital of Pakistan, but the official capital of Pakistan is Islamabad. This breaks the country-capital relationship established in the other pairs.

Explanation

To arrange the words in alphabetical order as they appear in an English dictionary, we compare them letter by letter from left to right.

First letter: All words start with L.

Second letter: Layout has a, while Lean, League, Lecture, and Leftist have e. Since a comes before e, Layout (4) comes first.

Third letter: Among the remaining words, Lean and League have a, Lecture has c, and Leftist has f. Since a comes before c, and c comes before f, Lean and League come next, followed by Lecture (3), and then Leftist (5).

Fourth letter: To determine the order between League and Lean, we compare their fourth letters, g and n. Since g comes before n, League (2) comes before Lean (1).

Combining these steps gives the correct alphabetical sequence: Layout (4), League (2), Lean (1), Lecture (3), Leftist (5), which is 4, 2, 1, 3, 5.

Explanation

The pattern in the given number pairs is based on a constant difference between the two numbers in each pair.

By analyzing the first two pairs: 552 - 319 = 233 379 - 146 = 233

Applying the same constant difference of 233 to the third pair: 774 - x = 233 x = 774 - 233 = 541

Explanation

In the letter group GJJL, the alphabetical positions of the letters are G = 7, J = 10, J = 10, and L = 12. The numerical differences between consecutive letters are +3, 0, and +2. This pattern of differences deviates from the standard pattern of +3, 0, and +3, making GJJL the odd letter group.

Explanation

The relationship between the numbers (a, b, c) in each set is defined by the formula: c = 2 × (a² + b²)

Applying this to the first given set (14, 17, 970): 2 × (14² + 17²) = 2 × (196 + 289) = 2 × 485 = 970

Applying this to the second given set (15, 23, 1508): 2 × (15² + 23²) = 2 × (225 + 529) = 2 × 754 = 1508

Applying this same relationship to option A (17, 24, 1730): 2 × (17² + 24²) = 2 × (289 + 576) = 2 × 865 = 1730

Explanation

Comparing the word BOLT (2965) and TADY (0368), the only common letter is T, and the only common digit is 6. Thus, T = 6.

Comparing BOLT (2965) and DOLE (5723), the common letters are O and L, and the common digits are 2 and 5. Thus, {O, L} = {2, 5}.

In BOLT (2965), since T = 6 and {O, L} = {2, 5}, the remaining letter B must correspond to the remaining digit 9. Thus, B = 9.

Comparing DOLE (5723) and TADY (0368), the only common letter is D, and the only common digit is 3. Thus, D = 3.

Comparing MASB (4819) and TADY (0368), the only common letter is A, and the only common digit is 8. Thus, A = 8.

In TADY (0368), since T = 6, A = 8, and D = 3, the remaining letter Y must be 0.

In DOLE (5723), since D = 3 and {O, L} = {2, 5}, the remaining letter E must correspond to 7.

To code BTO, we need the digits for B, T, and O, which are 9, 6, and either 2 or 5. This gives the combination of digits 9, 6, and 2.

Explanation

By decoding the letter symbols as standard mathematical operators to make the expression consistent: R represents division (÷) P represents multiplication (×) Q represents addition (+) S represents subtraction (-)

Substituting these operators into the given expression: 56 ÷ 8 + 13 - 42 ÷ 21 × 5

According to the BODMAS rule, perform the division operations first: 56 ÷ 8 = 7 42 ÷ 21 = 2

Substitute these values back into the expression: 7 + 13 - 2 × 5

Next, perform the multiplication operation: 2 × 5 = 10

The expression becomes: 7 + 13 - 10

Now, perform the addition: 7 + 13 = 20

Finally, perform the subtraction: 20 - 10 = 10

Explanation

The word pair Gun - Shoot follows the sequence of tool followed by its action, whereas the other pairs follow the sequence of action followed by the tool used to perform that action. This reversal of order makes it the odd pair.

Explanation

To arrange the words in alphabetical order as they appear in a dictionary, compare them letter by letter from left to right.

Comparing the first four letters of each word: Manage and Manager both start with Mana. Manger, Mango, and Mangrove start with Mang. Since a comes before g in the alphabet, the words starting with Mana come first.

Comparing Manage and Manager, Manage is shorter and is a prefix of Manager, so Manage comes before Manager. This gives the sequence 4, 5.

Next, compare the remaining words starting with Mang by looking at their fifth letter: In Manger, the fifth letter is e. In Mango, the fifth letter is o. In Mangrove, the fifth letter is r.

Arranging these fifth letters in alphabetical order gives e, then o, and then r. Therefore, Manger comes first, followed by Mango, and then Mangrove. This gives the sequence 1, 2, 3.

Combining both parts, the complete correct alphabetical sequence is 4, 5, 1, 2, 3.

Explanation

Based on the first statement, all Fruits are inside the set of Vegetables. Since all Fruits are Vegetables, the reverse relation that some Vegetables are Fruits is always true. Thus, Conclusion I follows.

Based on both statements, all Fruits are Vegetables and all Vegetables are Almonds. This means the set of Fruits is entirely contained within the set of Almonds. Since all Fruits are Almonds, it logically follows that some Fruits are Almonds. Thus, Conclusion III follows.

Conclusion II does not follow because the set of Almonds is larger than the set of Vegetables, and we cannot guarantee that all Almonds are Vegetables. Therefore, only conclusions I and III follow.

Explanation

The given series follows a multiplication pattern where each consecutive term is multiplied by an increasing integer starting from 1.

10 × 1 = 10 10 × 2 = 20 20 × 3 = 60 60 × 4 = 240 240 × 5 = 1200

Following this pattern, the next number in the series is obtained by multiplying the fifth term by 5, which gives 1200.

Explanation

The relationship established in the first pair is Tool : Professional, as a plumbline is a fundamental tool used by a mason to ensure walls are perfectly vertical. Similarly, a saw is a primary tool used by a carpenter to cut and shape wood, matching the exact same tool-to-professional relationship and order.

Explanation

To find the code, first reverse the letters of the word and then subtract 4 and 2 alternately from their alphabetical positions.

For BOUCLE: Reversed word: E L C U O B Alphabetical positions: 5, 12, 3, 21, 15, 2 Applying the alternate subtraction (-4, -2, -4, -2, -4, -2): 5 - 4 = 1 (A) 12 - 2 = 10 (J) 3 - 4 = -1 = 25 (Y) 21 - 2 = 19 (S) 15 - 4 = 11 (K) 2 - 2 = 0 = 26 (Z) This gives the code AJYSKZ.

Applying the same logic to BOUDIN: Reversed word: N I D U O B Alphabetical positions: 14, 9, 4, 21, 15, 2 Applying the alternate subtraction (-4, -2, -4, -2, -4, -2): 14 - 4 = 10 (J) 9 - 2 = 7 (G) 4 - 4 = 0 = 26 (Z) 21 - 2 = 19 (S) 15 - 4 = 11 (K) 2 - 2 = 0 = 26 (Z) This gives the code JGZSKZ.

Explanation

Each letter in the four-letter term follows a specific arithmetic sequence based on its alphabetical position from A = 1 to Z = 26:

First letter: Remains constant as P.

Second letter: Decreases by 4 in each step. H (8) - 4 = D (4) D (4) - 4 = Z (26) Z (26) - 4 = V (22) V (22) - 4 = R (18) Thus, the second letter is Z.

Third letter: Decreases by 8 in each step (modulo 26). D (4) - 8 = V (22) V (22) - 8 = N (14) N (14) - 8 = F (6) F (6) - 8 = X (24) Thus, the third letter is N.

Fourth letter: Decreases by 12 in each step (modulo 26). T (20) - 12 = H (8) H (8) - 12 = V (22) V (22) - 12 = J (10) J (10) - 12 = X (24) Thus, the fourth letter is V.

Combining these letters yields the missing term PZNV.
