RRB NTPC CBT 1 2026 General Intelligence & Reasoning Questions with Solutions

Explanation

Comparing the words 'LIME' (coded as 4839) and 'TIME' (coded as 9324), the common letters are 'I', 'M', and 'E', and the corresponding common digits are 3, 4, and 9.

The letter 'T' is unique to 'TIME' and the digit 2 is the only unique digit present in the code 9324. Thus, the code for 'T' is 2.

Explanation

The pattern in the series is based on adding consecutive multiples of 4:

11 − 7 = 4 19 − 11 = 8 31 − 19 = 12 47 − 31 = 16

The difference increases by 4 at each step. Following this pattern, the next difference is 16 + 4 = 20.

Missing number = 47 + 20 = 67.

Explanation

Tracking Pawan's movement using Cartesian coordinates starting from Point A at (0, 0): Drives 25 km North to (0, 25) Turns Right (East) and drives 15 km to (15, 25) Turns Right (South) and drives 32 km to (15, -7) Turns Right (West) and drives 26 km to (-11, -7) Turns Right (North) and drives 7 km to (-11, 0), which is Point P.

Point P is situated 11 km West of Point A. To reach Point A from Point P, Pawan needs to travel 11 km towards the East.

Explanation

In the standard alphabetical sequence, the pattern followed by the group consists of letters increasing by a uniform positional difference of 2 across the cluster pair. In TU- WX, the positional values are T(20), U(21), W(23), and X(24). The letters within each cluster differ by a positional increment of 1 (+1) instead of 2 (+2), which violates the group rule.

Explanation

The pattern follows an alternating addition and subtraction of 2 to the alphabetical position of each letter (+2, -2, +2, -2).

M (+2) = O, U (-2) = S, N (+2) = P, I (-2) = G S (+2) = U, D (-2) = B, I (+2) = K, K (-2) = I

Applying the same rule to BZMP gives: B (+2) = D Z (-2) = X M (+2) = O P (-2) = N

This results in the letter group DXON.

Explanation

Substituting the given letters with their mathematical operators (A = ÷, B = ×, C = +, D = −) yields the expression:

18 ÷ 2 × 5 + 7 − 9

Applying BODMAS order of operations: Division: 18 ÷ 2 = 9 Multiplication: 9 × 5 = 45 Addition: 45 + 7 = 52 Subtraction: 52 − 9 = 43

Explanation

N lives on an odd floor other than 5, so N is on floor 1 or 3. Since the sum of the floors of N and Z is 5, if N were on floor 1, Z would be on floor 4, making it impossible to place X with 3 people between Z and X on 6 floors. Thus, N lives on floor 3 and Z lives on floor 2.

Since 3 people live between Z and X, X must live on floor 6. C lives immediately above V, which places C on floor 5 and V on floor 4, leaving B on floor 1. Because Z is on floor 2, exactly 1 person lives below Z.

Explanation

Let seven positions around the circular table facing centre be numbered 1 to 7 in clockwise order, where clockwise represents to the left and counter-clockwise represents to the right.

Placing N at position 1: Q sits third to the left of N, so Q is at position 4. N is an immediate neighbour of both L and M, so L and M occupy positions 2 and 7. If M were at position 2, M being second to the left of R would put R at position 7, which overlaps with L. Thus, M is at position 7 and L is at position 2. M is second to the left of R, placing R at position 5. K is not an immediate neighbour of Q (position 4), so K must be at position 6, which leaves P at position 3.

The complete clockwise arrangement is N (1), L (2), P (3), Q (4), R (5), K (6), and M (7).

Counting from the right of P (counter-clockwise from position 3 to position 7), the people sitting between P and M are L and N. Thus, there are 2 people between them.

Explanation

To find a symbol that is immediately preceded by a letter and immediately followed by another symbol, look for the pattern: Letter - Symbol - Symbol.

Scanning the series from left to right, only the combination D # satisfies this requirement, where the symbol is preceded by the letter D and followed by the symbol #.

Explanation

Assigning each person to their exam day from Monday to Sunday using the provided clues gives the following schedule:

Since G has an exam on Friday and two people are between M and G, M must have an exam on Tuesday (Wednesday and Thursday are in between).

Four people are between F and M, which places F on Sunday (Wednesday, Thursday, Friday, and Saturday are in between).

N is scheduled immediately after O. The only consecutive vacant days remaining are Wednesday and Thursday, so O is on Wednesday and N is on Thursday.

L does not have an exam on Monday, placing L on Saturday and leaving H with Monday.

The final order from Monday to Sunday is H, M, O, N, G, L, F.

Counting the days between H on Monday and L on Saturday gives Tuesday, Wednesday, Thursday, and Friday (M, O, N, and G), making a total of four people.

Explanation

Comparing the two words 'WEAR' and 'CAST', the only common letter between them is 'A'. Similarly, comparing their respective numerical codes '8246' and '3851', the only common digit is '8'. Therefore, the code for 'A' is 8.

Explanation

The relation among the numbers in each set (A, B, C) follows the pattern: C = 3 × B - A.

Applying this rule to the given sets: Set 1: 3 × 11 - 9 = 33 - 9 = 24 Set 2: 3 × 14 - 15 = 42 - 15 = 27

Applying the same rule: 3 × 11 - 2 = 33 - 2 = 31

Explanation

The pattern in the series involves subtracting consecutive prime numbers from each preceding term:

81 - 2 = 79 79 - 3 = 76 76 - 5 = 71 71 - 7 = 64

The prime number following 7 is 11. Subtracting 11 from 64 gives: 64 - 11 = 53

Explanation

Dropping all the numbers (8, 9, 7, 6, 9, 4, 2, 1) from the series leaves the following non-numeric elements in order from left to right: @, @, €, E, X, €, S, N, %, , €, #, O, N.

Counting from the left, the eighth element in this modified sequence is N.

Explanation

The pattern followed in the given sets is a positional letter shift of +3, -2, and +3 for the first, second, and third letters respectively.

For LUB to OSE: L (+3) → O U (-2) → S B (+3) → E

For RQH to UOK: R (+3) → U Q (-2) → O H (+3) → K

Applying the same rule to XMN yields AKQ: X (+3) → A M (-2) → K N (+3) → Q

Explanation

Combining the universal affirmative statements "All flats are villas" and "All villas are apartments" directly yields "All flats are apartments", making conclusion (I) valid.

The statement "Some apartments are buildings" only establishes an overlap between apartments and buildings. It does not mandate any intersection between villas and buildings, so conclusion (II) does not follow.

Explanation

In the given sets of numbers, each subsequent number is obtained by adding consecutive increments of 15, 25, and 35 to the preceding term:

First set: 25 + 15 = 40 40 + 25 = 65 65 + 35 = 100

Second set: 70 + 15 = 85 85 + 25 = 110 110 + 35 = 145

Following the same pattern: 50 + 15 = 65 65 + 25 = 90 90 + 35 = 125

Explanation

To find the second digit from the left end, consider the second digit of the given number 5267341, which is 2.

Since 2 is an even digit, applying the rule of subtracting 2 gives 2 - 2 = 0.

Explanation

L lives on floor 6 since floor 4 is excluded and placing L on floor 2 creates a conflict with F. With two people between L and E, E lives on floor 3. D lives on odd floor 5, which places F immediately below D on floor 4. Since two people live between D and N, N lives on floor 2. The remaining floor 1 is occupied by M, placing N on floor 2 directly above M.

Explanation

Statement I gives N > L, which lacks information about M, T, and V.

Statement II states that M is the second tallest tree (shorter than only one tree) and V > N, but gives no information about T and L.

Combining both statements gives M as the second tallest tree and V > N > L. This allows multiple possible height arrangements from tallest to shortest, such as V > M > N > L > T (where T is the shortest) or V > M > N > T > L (where L is the shortest). Since it is impossible to uniquely determine whether L or T is the shortest tree, both statements together are not sufficient.

Explanation

The series follows four distinct patterns for each component:

First letter decreases by 3 positional values in the alphabet: B (2) - 3 = Y (25), Y (25) - 3 = V (22), V (22) - 3 = S (19), and S (19) - 3 = P (16).

Second letter decreases by 2 positional values: W (23) - 2 = U (21), U (21) - 2 = S (19), S (19) - 2 = Q (17), and Q (17) - 2 = O (15).

Third letter decreases by 1 positional value: J (10) - 1 = I (9), I (9) - 1 = H (8), H (8) - 1 = G (7), and G (7) - 1 = F (6).

Number increases by 5: 12 + 5 = 17, 17 + 5 = 22, 22 + 5 = 27, and 27 + 5 = 32.

Combining these results gives POF 32.

Explanation

Positioning seven persons facing the centre in counterclockwise order (immediate right direction), let B be at position 1. Counting two places to the right of B places D at position 4. Since D is to the immediate right of C, C is at position 3. Three persons sit between C and E when counted to the right of C, placing E at position 7. F sits to the immediate right of A, filling consecutive empty positions 5 and 6 with A and F respectively. The remaining position 2 is occupied by G. The sequence in counterclockwise order is B, G, C, D, A, F, E.

Since all persons face the centre, the immediate left corresponds to the clockwise direction: i. The immediate left of G is B (Z). ii. The immediate left of E is F (Y). iii. The immediate left of A is D (X). iv. The immediate left of C is G (W).

This matches i-Z, ii-Y, iii-X, iv-W.

Explanation

Combining the statements "All rabbits are yaks" and "All yaks are whales" yields the relation that all rabbits are whales. Since "No whale is a shark", no subset of whales can be a shark, which logically means "No rabbit is a shark" (Conclusion I). Furthermore, because all rabbits are whales, by conversion, "Some whales are rabbits" (Conclusion II).

Explanation

The pattern governing the letter clusters is that the second letter is 2 steps behind the first letter (-2), and the third letter is 5 steps ahead of the second letter (+5). In KFN (K=11, F=6, N=14), the position changes are -5 and +8 (11 - 5 = 6, 6 + 8 = 14), which does not follow the -2, +5 rule.

Explanation

The pattern followed by the numbers in each set (A, B, C) is: B = A² × C

For the given sets: 8² × 2 = 64 × 2 = 128 9² × 3 = 81 × 3 = 243

Applying the same relation: 7² × 7 = 49 × 7 = 343

Explanation

The series follows two distinct patterns for the letter clusters and the numbers:

Each letter shifts backward by 7 positions in the alphabet: First letter: D(4) - 7 = W(23) - 7 = P(16) - 7 = I(9) - 7 = B(2) Second letter: R(18) - 7 = K(11) - 7 = D(4) - 7 = W(23) - 7 = P(16) Third letter: J(10) - 7 = C(3) - 7 = V(22) - 7 = O(15) - 7 = H(8)

The numbers decrease by 5 in each step: 50 - 5 = 45 - 5 = 40 - 5 = 35 - 5 = 30

Combining these gives BPH 30.

Explanation

Deconstructing the expression K + L - M x N ÷ O step by step:

N ÷ O means N is the brother of O. M x N means M is the mother of N, so M is also the mother of O. L - M means L is the husband of M, which makes L the father of O. K + L means K is the sister of L.

Since L is the father of O and K is the sister of L, K is O's father's sister.

Explanation

By comparing both coded statements, the only word common to 'kids are playing' and 'people love kids' is 'kids'. Similarly, the only code word common to 'pu rs bp' and 'rs gu xc' is 'rs'. Therefore, 'kids' is coded as 'rs'.

Explanation

The relationship between the first number (x) and the second number (y) in the given sets follows the rule: y = (x × 2) - 1.

For the set (15, 29): 15 × 2 - 1 = 30 - 1 = 29. For the set (32, 63): 32 × 2 - 1 = 64 - 1 = 63.

Applying the same operation to the pair (17, 33): 17 × 2 - 1 = 34 - 1 = 33.

Explanation

Comparing the words 'LITE' and 'EDIT', the common letters are E, I, and T. Comparing their respective codes '1527' and '5124', the common digits are 1, 5, and 2. Removing these common elements leaves the letter 'D' in 'EDIT' and the digit 4 in '5124'.

Explanation

In categorical syllogism, combining two negative premises (Type E) yields no definite conclusion regarding the terms that are not shared.

For Conclusion (I), the relation between elephant and donkey involves two negative statements: "No elephant is a horse" and "No horse is a donkey". Since no valid conclusion can be drawn from two negative statements, a direct relationship between elephant and donkey cannot be established with certainty, so conclusion (I) does not follow.

For Conclusion (II), the relation between turtles and donkeys also relies on two negative statements: "No horse is a donkey" and "No horse is a turtle". Two negative premises do not produce any definite relationship between turtles and donkeys, so conclusion (II) does not follow.

Explanation

The pattern follows an alternating positional shift of -1, +1, -1, +1 in the English alphabetical order.

F (-1) = E, I (+1) = J, B (-1) = A, A (+1) = B → EJAB Z (-1) = Y, E (+1) = F, L (-1) = K, U (+1) = V → YFKV

Applying the same logic to COIS: C (-1) = B O (+1) = P I (-1) = H S (+1) = T

This gives BPHT.

Explanation

When seven people sit around a circular table facing the centre, moving clockwise represents moving to the left, and moving counter-clockwise represents moving to the right.

Assigning positions 1 to 7 in clockwise order: Place S at position 1. Since T sits to the immediate left of S, T is at position 2. E sits third to the left of S, placing E at position 4. To satisfy D sitting second to the left of G and U sitting to the immediate left of D, G must be at position 3, D at position 5, and U at position 6. The remaining position 7 is occupied by F.

Moving 4 steps counter-clockwise (to the right) from F at position 7 leads to position 3, which is occupied by G.

Explanation

Floor 4 is occupied by E.

Two people live between E and R, placing R on floor 1.

S lives immediately below E, placing S on floor 3.

Only P lives between E and Q, placing P on floor 5 and Q on floor 6.

The remaining floor, floor 2, is occupied by F.

Explanation

The given series follows two separate logic patterns for the letters and the numbers:

For the letters, every position advances by 2 places in alphabetical order: First letter: D (+2) → F (+2) → H (+2) → J (+2) → L Second letter: C (+2) → E (+2) → G (+2) → I (+2) → K Third letter: E (+2) → G (+2) → I (+2) → K (+2) → M

For the numbers, each term decreases by 5: 19 (-5) → 14 (-5) → 9 (-5) → 4 (-5) → -1

Combining the letters and the number gives LKM -1.

Explanation

Each letter in the given word is shifted forward by 2 positions in the English alphabetical order (+2 pattern):

G (+2) → I, O (+2) → Q, A (+2) → C, T (+2) → V O (+2) → Q, W (+2) → Y, I (+2) → K, B (+2) → D

Applying the same rule to UCOH: U (+2) → W C (+2) → E O (+2) → Q H (+2) → J

This yields WEQJ.

Explanation

The positional shift pattern for consecutive letters in the alphabet is +4, +3, +2, and +1 respectively.

J (+4) = N, E (+3) = H, L (+2) = N, U (+1) = V B (+4) = F, G (+3) = J, M (+2) = O, Q (+1) = R

Applying the same logic to GKNP gives: G (+4) = K K (+3) = N N (+2) = P P (+1) = Q

Combining these yields KNPQ.

Explanation

Original digits: 1, 8, 4, 7, 5, 3, 6 Ascending order: 1, 3, 4, 5, 6, 7, 8

Comparing each position from left to right: 1st position: 1 (original) = 1 (sorted) 2nd position: 8 (original) ≠ 3 (sorted) 3rd position: 4 (original) = 4 (sorted) 4th position: 7 (original) ≠ 5 (sorted) 5th position: 5 (original) ≠ 6 (sorted) 6th position: 3 (original) ≠ 7 (sorted) 7th position: 6 (original) ≠ 8 (sorted)

The digits 1 and 4 remain at the 1st and 3rd positions respectively, giving a total of two unchanged positions.

Explanation

E lives on floor 6 (topmost). Since three people live between E and M, M lives on floor 2. O lives on a floor below M, so O lives on floor 1. Among the remaining available floors (3, 4, and 5), N lives on an even-numbered floor, which means N lives on floor 4. P lives on an odd-numbered floor other than floor 5, which places P on floor 3. This leaves F to occupy floor 5. The final floor arrangement from top to bottom is E (floor 6), F (floor 5), N (floor 4), P (floor 3), M (floor 2), and O (floor 1). Between F on floor 5 and M on floor 2, there are 2 people (N and P).

Explanation

Arranging the seven people around the circular table facing the centre in clockwise order:

Placing G at position 1, V sits fourth to the left (clockwise) of G at position 5. Since W is a neighbour of both V and I, placing W at position 6 puts I at position 7. Counting three people to the right of I puts F at position 3. H sits to the immediate right of F at position 2. The remaining person U occupies position 4.

The clockwise sequence is G, H, F, U, V, W, I. Counting three places to the left (clockwise) from U at position 4 leads to position 7, where I is seated.

Explanation

In the rule governing the group, the letters of the second cluster are obtained by adding 2 to the alphabetical position of the corresponding letters in the first cluster. In FI-JM, the letters J and M are obtained by adding 4 to the positions of F and I respectively (F = 6, J = 10 and I = 9, M = 13), making it the odd cluster pair.

Explanation

Decoding the given expression step-by-step: R - P means R is the wife of P, which makes P the husband of R. P + S means P is the father of S, so R is the mother of S. S × N means S is the sister of N, meaning S and N are siblings, so R is also the mother of N. N ÷ F means N is the mother of F.

Since N is the mother of F, and R is the mother of N, R is the mother's mother of F.

Explanation

The pattern in the series involves adding consecutive prime numbers to each term:

91 + 2 = 93 93 + 3 = 96 96 + 5 = 101 101 + 7 = 108

The next prime number after 7 is 11.

108 + 11 = 119

Explanation

Set Point A as the origin (0, 0) on a coordinate system where North-South is the y-axis and East-West is the x-axis:

Start at A: (0, 0) Drive 37 km West: (-37, 0) Turn right (North) and drive 26 km: (-37, 26) Turn right (East) and drive 42 km: (-37 + 42, 26) = (5, 26) Turn right (South) and drive 47 km: (5, 26 - 47) = (5, -21) Turn right (West) and drive 5 km: (5 - 5, -21) = (0, -21) at Point P

Point P is located at (0, -21), which is 21 km directly South of Point A. Therefore, to reach Point A from Point P, Kartikeyan must drive 21 km towards the North.

Explanation

For conclusion I, all vultures are sparrows and some sparrows are crows, but the sparrows that are crows do not necessarily overlap with vultures. Hence, a definite relation between vultures and crows cannot be established.

For conclusion II, no crow is a pigeon, but this rule applies strictly to crows. Sparrows that are not crows can still be pigeons, so a universal negative relation between sparrows and pigeons cannot be inferred.

Since both conclusions are only possibilities and not definite logical certainties, neither conclusion I nor II follows.

Explanation

The pattern in the given series is based on adding the squares of consecutive natural numbers to each preceding term:

23 + 1² = 24 24 + 2² = 28 28 + 3² = 37 37 + 4² = 53 53 + 5² = 78

Explanation

The standard operations connecting the consecutive numbers in each given set are: 1st number × 3 = 2nd number 2nd number + 15 = 3rd number 3rd number + 12 = 4th number

Testing this rule on the given sets: 12 × 3 = 36, 36 + 15 = 51, 51 + 12 = 63 20 × 3 = 60, 60 + 15 = 75, 75 + 12 = 87

Applying the same sequence of operations: 25 × 3 = 75 75 + 15 = 90 90 + 12 = 102

Explanation

The seven days from Monday to Sunday correspond to positions 1 through 7.

S flies on the third last day of the week, which is Friday (position 5). Since two people fly between R and S, R must fly on Tuesday (position 2). Four people fly between R and Q, placing Q on Sunday (position 7).

P flies immediately after N, which requires two consecutive empty slots. The only available consecutive days are Wednesday (position 3) and Thursday (position 4), so N flies on Wednesday and P flies on Thursday.

The remaining unassigned days are Monday (position 1) and Saturday (position 6). Since M does not fly on Monday, M flies on Saturday.

Explanation

The pattern followed by the numbers (a, b, c) in the given sets is:

c = 3a + b

For (7, 18, 39): (3 × 7) + 18 = 21 + 18 = 39

For (3, 19, 28): (3 × 3) + 19 = 9 + 19 = 28

Similarly, for (23, 4, 73): (3 × 23) + 4 = 69 + 4 = 73

Explanation

Arranging the given numbers in descending order: 769 > 564 > 546 > 487 > 478.

The second highest number is 564, whose second digit is 6. The lowest number is 478, whose third digit is 8.

Adding the two digits gives: 6 + 8 = 14.
