Show answer & explanationHide answer

Answer: (C) TVXZ

Explanation

The relationship between the first two sets of letters is based on a constant positional shift in the English alphabet. By converting each letter of ACEG to its numerical position, we get A=1, C=3, E=5, and G=7. Similarly, for SUWY, the positions are S=19, U=21, W=23, and Y=25. Comparing these, each letter in the first group is shifted forward by 18 positions to obtain the corresponding letter in the second group (1+18=19, 3+18=21, 5+18=23, 7+18=25).

Applying this same +18 logic to the third set BDFH: B (2) + 18 = 20 (T) D (4) + 18 = 22 (V) F (6) + 18 = 24 (X) H (8) + 18 = 26 (Z)

Following the sequence of these numerical results, we arrive at the letters TVXZ.

Answer: (A) P/AF

Explanation

The pattern involves an alphabetical increment of +1 for both the numerator and the second letter of the denominator. In the first pair, the numerator shifts from M to N, and the denominator suffix changes from C to D while the prefix A remains constant. Applying this identical logic to the term O/AE, the numerator O increments to P, and the denominator suffix E increments to F. This results in the term P/AF.

Answer: (C) 20

Explanation

The relationship between the numbers in each pair follows the mathematical pattern y = 2x - n, where n is an integer that increments by 1 for each successive pair in the analogy. For the first pair, substituting x = 6 and n = 1 results in 6 × 2 - 1 = 11. For the second pair, the value of n increases to 2; substituting x = 11 into the formula gives 11 × 2 - 2 = 20.

Show answer & explanationHide answer

Answer: (C) 38

Explanation

The relationship is determined by the sum of the numerical positions of the letters in the English alphabet. For the term ABE, the positional values are A = 1, B = 2, and E = 5. Adding these values together gives 1 + 2 + 5 = 8. Applying the same logic to the term KLO, the positional values are K = 11, L = 12, and O = 15. The sum of these values is 11 + 12 + 15 = 38.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (B) MPNO

Explanation

The relationship between the letter groups is based on a constant shift of +4 positions in the alphabetical order for each corresponding letter. By examining the first pair ADBC and EHFG, the transformation is as follows: A (1) + 4 = E (5), D (4) + 4 = H (8), B (2) + 4 = F (6), and C (3) + 4 = G (7).

Applying this same +4 shift logic to the third group ILJK results in the following positions: I (9) + 4 = M (13), L (12) + 4 = P (16), J (10) + 4 = N (14), and K (11) + 4 = O (15). Mapping these numerical values back to their respective letters in the alphabet produces the sequence MPNO.

Answer: (D) 9,64

Explanation

The pair 9 and 64 consists of the squares 3² and 8². This response is different because the integers 3 and 8 are not consecutive. While the pattern for such sets typically involves squares of consecutive natural numbers n² and (n+1)², the difference between the base roots in this specific option is 5 rather than 1. This makes the pair the unique outlier in the group.

Answer: (C) Tide

Explanation

Tides are uniquely characterized by their astronomical origin, as they are caused by the gravitational interaction between the Earth, the Moon, and the Sun. This gravitational basis ensures that tides follow a highly predictable and periodic cycle of rising and falling sea levels. This distinguishes them from the other phenomena listed, which are primarily driven by atmospheric conditions, wind patterns, and pressure variations rather than celestial gravity.

Answer: (B) y

Explanation

The letter y is written in lowercase. In reasoning tests involving the alphabet, the case of the letter—whether it is an uppercase capital or a small lowercase letter—is a fundamental method for isolating a distinct entry. This character is represented in its small-letter form, which serves as its identifying feature. The visual distinction between capital and small letters is the primary basis for this classification.

Answer: (D) FRTK

Explanation

The numerical positions of the letters in the sequences follow a specific pattern involving alternating letters. In the first three options, the difference between the first and third letters is 2, while the difference between the second and fourth letters is 1. Specifically, the third letter is found by subtracting 2 from the position of the first letter (P₁ - 2 = P₃), and the fourth letter is found by subtracting 1 from the position of the second letter (P₂ - 1 = P₄).

In ZKXJ, Z(26) - 2 = X(24) and K(11) - 1 = J(10). In CMAL, C(3) - 2 = A(1) and M(13) - 1 = L(12). In TGRF, T(20) - 2 = R(18) and G(7) - 1 = F(6). In FRTK, the relationship between the first letter F(6) and the third letter T(20) is an addition of 14, and the relationship between the second letter R(18) and the fourth letter K(11) is a subtraction of 7. This deviation from the P₁ - 2 and P₂ - 1 logic makes FRTK the distinct response.

Answer: (C) IXYQQ

Explanation

The sequence IXYQQ is the distinct response because it contains a repeated letter, which is Q. All other options consist of five unique letters with no repetitions. In classification tests of this type, a variation in the composition of characters, such as the duplication of a letter within a single group while others maintain unique sets, identifies the odd one out.

Tap an option to check yourself

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (D) 4,1,5,3,2

Explanation

To arrange words according to a dictionary, we compare them letter by letter from left to right. All five words begin with the prefix Inv. Comparing the fourth letter of each word, Invariable contains a, which is the first letter alphabetically, placing it first in the sequence (4). Next, both Inventory and Investigate have e as their fourth letter. By comparing their fifth letters, n in Inventory precedes s in Investigate, which ranks Inventory second (1) and Investigate third (5). Following these, Invisible has i as its fourth letter, and Involuntary has o. In the alphabet, i comes before o, so Invisible is fourth (3) and Involuntary is fifth (2). The correct dictionary order is 4, 1, 5, 3, 2.

Show answer & explanationHide answer

Answer: (C) QW

Explanation

The series is determined by the numerical positions of the letters in the English alphabet, where the difference between consecutive terms increases by 1 at each step. The positions of the given letters are B (2), C (3), E (5), H (8), and L (12). Calculating the differences between consecutive positions, we find 3 - 2 = 1, 5 - 3 = 2, 8 - 5 = 3, and 12 - 8 = 4. To find the next letter in the sequence, the difference must be 4 + 1 = 5, making the next position 12 + 5 = 17, which corresponds to the letter Q. For the following letter, the difference must be 5 + 1 = 6, making the position 17 + 6 = 23, which corresponds to the letter W.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (B) bnbban

Explanation

The series is completed by dividing the letters into four groups of four letters each. By sequentially placing the letters from option b) bnbban into the gaps, the sequence follows a systematic pattern of permutations and repetitions of the letters a, b, and n.

The original string with gaps is: a _ b _ a _ n _ b b _ a b b n (with an implied gap at the end).

Substituting the letters b, n, b, b, a, n into the six gaps: 1st gap: b 2nd gap: n 3rd gap: b 4th gap: b 5th gap: a 6th gap: n

The completed series becomes: a (b) b (n) | a (b) n (b) | b b (a) a | b b n (n)

This results in the following four groups: Group 1: abbn Group 2: abnb Group 3: bbaa Group 4: bbnn

This arrangement forms a logical sequence where each block of four letters is composed of specific combinations of the letters present in the series, completing the pattern as required.

Show answer & explanationHide answer

Answer: (D) 8,48,192

Explanation

The relationship between the numbers in the given set (6, 30, 90) follows a specific multiplication pattern where the second number is a multiple of the first, and the third number is a multiple of the second using a multiplier that is exactly 2 less than the first multiplier.

In the given set (6, 30, 90): The first multiplier k is 30 ÷ 6 = 5. The second multiplier is 90 ÷ 30 = 3. Observe that 3 = 5 - 2.

Applying this logic to the set (8, 48, 192): The first multiplier k is 48 ÷ 8 = 6. The second multiplier is 192 ÷ 48 = 4. Observe that 4 = 6 - 2.

The pattern y = x × k and z = y × (k - 2) is consistently maintained, making this set the most similar to the one provided in the question.

Show answer & explanationHide answer

Answer: (D) 41

Explanation

The given sequence follows a pattern of constant subtraction. Each term is obtained by subtracting 28 from the preceding term.

126 - 28 = 98 98 - 28 = 70 70 - 28 = 42 42 - 28 = 14

According to this common difference, the fourth term in the series should be 42. Since the series provides the number 41 in that position, it is the wrong number in the sequence.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (A) GMSYE

Explanation

The series follows a pattern where each subsequent term is formed by shifting each letter of the previous term forward by two positions in the English alphabet. By examining the positions of the letters (A=1, B=2, ..., Z=26), we can observe the progression for each corresponding character in the strings.

For the first letter, the sequence is A (1), C (3), E (5), which indicates a +2 increment, leading to G (7). For the second letter, the sequence is G (7), I (9), K (11), which indicates a +2 increment, leading to M (13). For the third letter, the sequence is M (13), O (15), Q (17), which indicates a +2 increment, leading to S (19). For the fourth letter, the sequence is S (19), U (21), W (23), which indicates a +2 increment, leading to Y (25). For the fifth letter, the sequence is Y (25), A (1/27), C (3/29), where the alphabet cycles back after Z. Adding 2 to C (3) results in E (5).

Applying this constant +2 addition to each letter of the third term EKQWC results in GMSYE. This pattern is further confirmed by the subsequent terms IOUAG and KQWCI, which continue the same +2 progression from GMSYE.

In each of the following questions, a series is given with one term missing. Choose the correct alternative from the given ones that will complete the series. 975,864,753,642,?
Tap an option to check yourself

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (C) 531

Explanation

The given sequence is an arithmetic series where each successive term is decreasing by a constant value. By calculating the difference between consecutive terms, we find:

975 - 864 = 111 864 - 753 = 111 753 - 642 = 111

Since the common difference is -111, the next term in the series is obtained by subtracting 111 from the last known term:

642 - 111 = 531

Another way to observe the pattern is by looking at the individual digits in each position. The hundreds digits follow the sequence 9, 8, 7, 6, the tens digits follow 7, 6, 5, 4, and the units digits follow 5, 4, 3, 2. In each case, the next digit in the sequence is one less than the previous one, leading to the digits 5, 3, and 1 respectively.

Show answer & explanationHide answer

Answer: (B) 36

Explanation

The given numerical series follows a logical pattern involving two alternating operations: multiplication by 3 and division by 2.

The sequence progresses as follows: 8 × 3 = 24 24 ÷ 2 = 12 12 × 3 = 36 36 ÷ 2 = 18 18 × 3 = 54

Following this alternating rule, the missing term is obtained by multiplying the third term, 12, by 3. This calculation yields 36. The pattern is confirmed by the next step, where 36 divided by 2 correctly results in the fifth term, 18.

Show answer & explanationHide answer

Answer: (B) 15 years

Explanation

Let Ashok's current age be x and his mother's current age be y. According to the first condition, five years ago, the mother was three times as old as Ashok: y - 5 = 3(x - 5) y - 5 = 3x - 15 y = 3x - 10

According to the second condition, five years from now, she will be twice as old as Ashok: y + 5 = 2(x + 5) y + 5 = 2x + 10 y = 2x + 5

By equating the two expressions for y: 3x - 10 = 2x + 5 3x - 2x = 10 + 5 x = 15

Show answer & explanationHide answer

Answer: (C) 33

Explanation

In a linear arrangement, the total number of individuals T is calculated using the formula T = L + R - 1, where L and R represent the positions of a single point from the left and right ends, respectively. When Srinath and Venkat interchange positions, Srinath moves to the spot previously occupied by Venkat. Since Venkat was originally 12th from the right, this position is fixed as the 12th spot from the right end of the row. The problem states that after the interchange, Srinath's new position is 22nd from the left. By applying the formula to this specific position, the total number of boys in the row is 22 + 12 - 1 = 33.

Answer: (C) 50

Explanation

The given series follows a pattern of squares of consecutive odd integers starting from 1. The sequence is generated by the formula n² where n = 1, 3, 5, 7, 9, …. Calculating the terms based on this logic gives: 1² = 1 3² = 9 5² = 25 7² = 49 9² = 81 Comparing these values to the provided series 1, 9, 25, 50, 81, the fourth term is 50 instead of the expected 49. Since 50 does not fit the established pattern of squares of odd numbers, it is the incorrect term in the series.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (B) 45

Explanation

Let the number of women who boarded the bus at Delhi be x. According to the problem, the number of men who boarded at Delhi was twice the number of women, which is 2x. The total number of initial passengers is the sum of men and women, represented as x + 2x = 3x.

At Meerut, the number of men decreased by ten and the number of women increased by five. The problem states that the number of men and women then became equal. This relationship can be expressed by the following equation:

2x - 10 = x + 5

Solving for x: 2x - x = 5 + 10 x = 15

The initial number of women was 15 and the initial number of men was 2 × 15 = 30. Therefore, the total number of passengers who boarded the bus initially at Delhi was 15 + 30 = 45.

Answer: (A) Sunday

Explanation

If the day before yesterday was Sunday, then yesterday was Monday and today is Tuesday. The day after tomorrow from Tuesday is Thursday. To find the day that falls three days after the day after tomorrow, we add three days to Thursday. Moving three days forward from Thursday (Friday, Saturday, Sunday) results in Sunday. In terms of day shifts, if today is D, then D - 2 = Sunday, making D = Tuesday. The target day is (D + 2) + 3 = D + 5, and five days after Tuesday is Sunday.

Statement: Politicians become rich by the votes of the people. Assumptions: I. People vote to make politician rich. II. Politicians become rich by their virtue.
Tap an option to check yourself

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (D) Both I and II are not implicit

Explanation

In logical reasoning, an assumption is an unstated premise that must be true for the statement to hold. The statement politicians become rich by the votes of the people describes a causal relationship where votes are the means through which politicians acquire wealth. However, it does not imply that the motive of the voters is to enrich the politician. Voters typically cast ballots for governance, representation, or policy, making the resulting wealth of the politician a byproduct rather than the intended goal of the act of voting. Furthermore, the statement explicitly attributes the accumulation of wealth to the acquisition of votes, which contradicts the idea that wealth is derived from personal virtue. Virtue refers to moral excellence or high standards of behavior, whereas the statement points to a specific political mechanism as the source of riches. Since neither the intent of the voters nor the moral character of the politician is necessary to support the original statement, both assumptions are not implicit.

Show answer & explanationHide answer

Answer: (C) Only 1, III and IV follow

Explanation

The relationship between the sets can be defined using the transitive property of inclusion. Since all men are women (M ⊂ W) and all women are crazy (W ⊂ C), it follows that all men are crazy (M ⊂ C). This validates Conclusion I. In standard syllogistic logic, a universal affirmative statement (All A are B) implies its partial converse (Some B are A). Therefore, because all men are crazy, it is logically necessary that some of the crazy are men, validating Conclusion III. Likewise, since the second premise states that all women are crazy, it is necessarily true that some of the crazy are women, validating Conclusion IV. Thus, I, III, and IV are logically sound deductions from the given premises.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (B) 725618

Explanation

The code is generated by assigned a specific digit to each letter in the word HOSPITAL according to its position. By mapping the letters to the digits provided in 32574618, we establish the following values: H = 3, O = 2, S = 5, P = 7, I = 4, T = 6, A = 1, and L = 8.

To determine the code for POSTAL, we extract the digits corresponding to its constituent letters from the established mapping. P corresponds to 7, O corresponds to 2, S corresponds to 5, T corresponds to 6, A corresponds to 1, and L corresponds to 8. Placing these digits in the required order yields the sequence 725618.

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (A) 22

Explanation

The pattern in this series involves calculating the sum of the digits of the numbers on the left and right sides of the parentheses to find the middle value. In the first row, for 173 (24) 526, the sum of the digits of 173 is 1 + 7 + 3 = 11 and the sum of the digits of 526 is 5 + 2 + 6 = 13. Adding these together gives 11 + 13 = 24.

In the second row, for 431 (18) 325, the sum of the digits of 431 is 4 + 3 + 1 = 8 and the sum of the digits of 325 is 3 + 2 + 5 = 10. Adding these together gives 8 + 10 = 18.

Following the same logic for the third row, 253 (?) 471, the sum of the digits of 253 is 2 + 5 + 3 = 10 and the sum of the digits of 471 is 4 + 7 + 1 = 12. The missing value is the sum of these two results: 10 + 12 = 22.

Show answer & explanationHide answer

Answer: (D) (12 + 6)× 18 = 36

Explanation

In the given equation (12 + 6) × 18 = 36, we must interchange the signs + and ÷, and the numbers 12 and 18. After applying these swaps, the number 12 becomes 18, the number 18 becomes 12, and the plus sign becomes a division sign. The transformed equation is:

(18 ÷ 6) × 12 = 36

Applying the BODMAS rule, we first perform the division inside the parentheses: 18 ÷ 6 = 3

Next, we multiply the result by 12: 3 × 12 = 36

The calculation yields 36, which matches the value on the right-hand side of the equation.

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (B) 100m

Explanation

To determine the distance from the starting point to the point where the child meets his father, we calculate the net displacement in the horizontal (East-West) and vertical (North-South) directions.

The child first moves 90 metres East. After turning right twice, he moves 30 metres West. The net horizontal distance from the starting point is 90 - 30 = 60 metres East.

Next, the child moves 20 metres South (his first right turn) and then 100 metres North. The net vertical distance from the starting point is 100 - 20 = 80 metres North.

The starting point and the final meeting point form a right-angled triangle where the base is 60 metres and the perpendicular height is 80 metres. Applying the Pythagoras theorem to find the hypotenuse d:

d = √(60² + 80²) d = √(3600 + 6400) d = √(10000) d = 100 metres

Show answer & explanationHide answer

Answer: (B) = x +

Explanation

Applying the sequence of signs =, ×, and + into the expression 24 A 4 A 5 A 4 results in the following mathematical equation: 24 = 4 × 5 + 4 To verify the validity of this equation, the operations on the right-hand side must be performed according to the standard order of operations, specifically the BODMAS rule. This rule dictates that multiplication takes precedence over addition. First, calculate the product of the first two numbers on the right side of the equal sign: 4 × 5 = 20 Next, add the final number in the sequence to this product: 20 + 4 = 24 The resulting value of the right-hand side is 24, which matches the value on the left-hand side. Because the left-hand side equals the right-hand side, this specific sequence of mathematical signs makes the equation correct.

Tap an option to check yourself

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (B) 48

Explanation

The sequence follows a pattern based on the position of each number within the three sets. Each number in a subsequent set is derived by multiplying the corresponding number from the previous set by 3 and then adding a constant that increases by 1 for each position.

For the first position in each set: 16 = (5 × 3) + 1 49 = (16 × 3) + 1

For the second position in each set: 29 = (9 × 3) + 2 89 = (29 × 3) + 2

For the third position in each set: (15 × 3) + 3 = 48 (48 × 3) + 3 = 147

The calculation for the third position in the second target yields 45 + 3 = 48. This result is consistent with the value in the third target, as 48 × 3 + 3 equals 147.

Answer: (A) DECAB

Explanation

The seating order from front to back is determined by arranging the children based on the given positional clues. From the statement that A is behind C but in front of B, we establish the relative order C-A-B. The condition that C is behind E further modifies this sequence to E-C-A-B. Finally, the information that D is sitting in front of E places D at the start of the sequence. By combining all these constraints, the final arrangement from the first row to the last row is D-E-C-A-B.

Show answer & explanationHide answer

Answer: (C) 12

Explanation

For a large cube of side n small cubes that is painted on all outer surfaces and then disassembled, the number of small cubes with exactly two sides painted is given by the formula 12(n - 2). These cubes are located along the edges of the larger cube, excluding the corner cubes which have three sides painted.

In this case, the side of the large cube is 3 inches and each small cube has a side of 1 inch, so n = 3 / 1 = 3. Substituting this value into the formula, we get 12(3 - 2) = 12 × 1 = 12. Each of the 12 edges of the large cube contains exactly one small cube that is not a corner, resulting in 12 cubes with paint on two sides.

Show answer & explanationHide answer

Answer: (C) West

Explanation

The movement from the capital P to the final point T can be analyzed by breaking each displacement into its horizontal (West) and vertical (North/South) components. Let the distance for each segment be d = 2 km.

The first movement from P to K is North-West, which consists of a westward component d cos 45° and a northward component d sin 45°. The second movement from K to R is South-West, consisting of a westward component d cos 45° and a southward component d sin 45°. Adding these two steps, the northward and southward components cancel each other out (d sin 45° - d sin 45° = 0), leaving a net displacement of 2d cos 45° exactly to the West.

The subsequent movements from R to M (North-West) and M to T (South-West) follow the same pattern. The northward component of the R-M leg is canceled by the southward component of the M-T leg. This adds another 2d cos 45° to the westward displacement. Consequently, the total vertical displacement from P to T is zero, and the total horizontal displacement is 4d cos 45° to the West. Therefore, T is located due West in relation to P.

Show answer & explanationHide answer

Answer: (A) South east

Explanation

Let Rahim's house be the origin (0, 0) on a Cartesian plane. Given that the distance for every movement is 200 metres and directions are exactly at 45-degree diagonals (NW, SW, SE, NE), we can use the displacement components d = 200/√2 for calculation.

Babu's house is North-West of Rahim's, placing it at (-d, d). Joseph's house is South-West of Rahim's, placing it at (-d, -d). Gopal's house is 200 metres South-East of Joseph's. Moving South-East from (-d, -d) involves adding d to the x-coordinate and subtracting d from the y-coordinate: (-d + d, -d - d) = (0, -2d). Roy's house is 200 metres North-East of Gopal's. Moving North-East from (0, -2d) involves adding d to both coordinates: (0 + d, -2d + d) = (d, -d).

To find Roy's position relative to Babu's, we calculate the displacement from Babu (-d, d) to Roy (d, -d). The change in the x-direction is d - (-d) = 2d (Eastward) and the change in the y-direction is -d - d = -2d (Southward). A movement that is simultaneously South and East results in a South-East direction.

Show answer & explanationHide answer

Answer: (A) Ravi

Explanation

In an octagonal seating arrangement facing the centre, the right direction is anti-clockwise and the left direction is clockwise. Opposite positions are four places apart (e.g., 1-5, 2-6, 3-7, 4-8).

Let the positions be numbered 1 to 8 in an anti-clockwise direction. Placing Sushma at position 1, we can determine the others:

Rama is on Sushma's right, so Rama is at position 2. Mahima is diagonally opposite Rama, placing Mahima at position 6 (2+4).

Ravi is next to Sushma. Since Rama is already at position 2, Ravi must be at position 8. Girdhar is opposite Ravi, so Girdhar is at position 4 (8-4).

Girdhar (4) is on Chandra's left. Since left is clockwise, Chandra must be at position 5 (as 4 is clockwise from 5). This also confirms that Chandra and Sushma are an opposite pair (1-5).

The remaining opposite pair of seats is 3 and 7, to be occupied by Savitri and Shalini. Savitri is not on Mahima's right. Mahima is at 6, and her right (anti-clockwise) is 7. Therefore, Savitri must be at position 3, and Shalini must be at position 7.

To find who is on Shalini's right, we look at the position anti-clockwise from Shalini (7), which is position 8. Ravi is seated at position 8.

Answer: (D) At the bottom

Explanation

A cube consists of six faces: the top, the bottom, and four lateral sides. The problem states that the top surface is blank. The remaining four lateral faces are occupied by the ellipse, cross, triangle, and square. This is determined by the positioning requirements: the ellipse is situated between the cross and the triangle, and the square is located to the right of the triangle. Since the ellipse and square are opposite each other, these four figures must form the sequence of the four lateral faces around the cube. With the top face being blank and the four lateral sides accounted for by the other four figures, the only remaining face for the circle to occupy is the bottom face.
