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

Explanation

The pattern follows a constant subtraction of 5 from the alphabetical position of each letter (-5 shift).

For the left pair, # = OTU yields JOP: O (15) - 5 = 10 (J) T (20) - 5 = 15 (O) U (21) - 5 = 16 (P)

For the right pair, YDE yields % = TYZ: Y (25) - 5 = 20 (T) D (4 + 26 = 30) - 5 = 25 (Y) E (5 + 26 = 31) - 5 = 26 (Z)

Explanation

The relationship between the letter-clusters in both pairs is formed by shifting each letter forward by 10 positions in the alphabetical series (A = 1, B = 2, ..., Z = 26):

For FPX : PZH F (6) + 10 = P (16) P (16) + 10 = Z (26) X (24) + 10 = H (8, wrapping around the alphabet)

For MWE : WGO M (13) + 10 = W (23) W (23) + 10 = G (7, wrapping around the alphabet) E (5) + 10 = O (15)

Explanation

Comparing the words 'OMIT' and 'TIME', the common letters are M, I, and T, which correspond to the common digits 2, 4, and 5 in their codes '4295' and '2458'.

The unique letter in 'TIME' is E, and the remaining unmatched digit in its code '2458' is 8. Therefore, the code for E is 8.

Explanation

The code is obtained by taking the sum of the standard alphabetical positional values of the letters in the word and multiplying the result by 2.

For VAJR: V(22) + A(1) + J(10) + R(18) = 51 51 × 2 = 102

For DOTG: D(4) + O(15) + T(20) + G(7) = 46 46 × 2 = 92

Applying the same rule to ZELW: Z(26) + E(5) + L(12) + W(23) = 66 66 × 2 = 132

Explanation

The pattern in the series involves subtracting consecutive prime numbers:

73 - 2 = 71 71 - 3 = 68 68 - 5 = 63 63 - 7 = 56

The next prime number after 7 is 11. Subtracting 11 from 56 gives 56 - 11 = 45.

Explanation

The pattern followed in the given number pairs is: Second number = (First number × 5) - 2.

Applying this rule: 51 × 5 - 2 = 255 - 2 = 253 38 × 5 - 2 = 190 - 2 = 188

Similarly, for 32: 32 × 5 - 2 = 160 - 2 = 158

Explanation

The given series follows a pattern where consecutive prime numbers are subtracted from each preceding term:

122 - 2 = 120 120 - 3 = 117 117 - 5 = 112 112 - 7 = 105

The sequence of prime numbers being subtracted is 2, 3, 5, 7, and the next prime number in sequence is 11. Subtracting 11 from 105 gives 105 - 11 = 94.

Explanation

In the standard pattern, the positional gap between letters within each cluster is +4, and the shift from the first cluster to the second cluster is +3. In FI-JM, this rule is inverted: the gap within each cluster is +3 (F = 6 to I = 9, and J = 10 to M = 13) and the shift between corresponding letters across the clusters is +4 (F = 6 to J = 10, and I = 9 to M = 13).

Explanation

Combining the statements "Some beds are pillows" and "All pillows are towels" leads to "Some beds are towels", which converts directly to "Some towels are beds". Hence, conclusion (II) logically follows.

Combining "All pillows are towels" and "All towels are cushions" yields "All pillows are cushions". From "All pillows are cushions", it only universally follows that "Some cushions are pillows", meaning conclusion (I) does not follow.

Explanation

Counting the non-number elements starting from the right end, the sequence of non-digit elements is G (1st), @ (2nd), R (3rd), (4th), D (5th), S (6th), and (7th). The numbers 7, 3, and 6 are skipped during the count, making the symbol the seventh element from the right.

Explanation

Since three people live between S and R with R below S, the possible floor pairs for (S, R) are (6, 2) or (5, 1). J lives immediately above R on an odd floor. If R were on floor 1, J would be on even floor 2, which is invalid. Thus, R lives on floor 2, J lives on floor 3, and S lives on floor 6.

reached floors for K, L, and T are 5, 4, and 1. Since L lives below K and above T, K occupies floor 5, L occupies floor 4, and T occupies floor 1.

Explanation

The pattern followed in the sets is: Second number = First number × Third number × 2

Applying this rule to the given sets: 34 × 16 × 2 = 1088 21 × 10 × 2 = 420

Similarly, for the set (28, 224, 4): 28 × 4 × 2 = 224

Explanation

Floor assignments can be determined directly from the given conditions: Floor 1 is occupied by T. Since two people live between T and Y, Y lives on Floor 4. Only S lives above U, which means S is on Floor 6 and U is on Floor 5. Z lives on an even-numbered floor, so Z must be on Floor 2. This leaves Floor 3 for X.

Comparing the positions of X (Floor 3) and T (Floor 1), only Z (Floor 2) lives between them, so exactly one person lives between X and T.

Explanation

Arranging the seven people around the circular table in a clockwise/counter-clockwise direction based on right-side movements:

Placing E at position 1, its immediate right gives F at position 2.

Since only three people sit between D and E when counted from the right of E, D is placed 4 steps to the right of E at position 5.

Since two people sit between G and F when counted from the right of G, G must be placed at position 7 (so that the two people to its right are at positions 1 and 6, reaching F at position 2).

Since A sits to the immediate right of B, B and A must occupy the adjacent vacant positions 3 and 4 respectively, leaving position 6 for C.

The arrangement in rightward order around the circle is E, F, B, A, D, G, C.

Counting from the left of G towards B, the people sitting between G and B are D and A, which equals 2 people.

Explanation

From the statement that all lakes are roads, every lake belongs to the category of roads. Combining this with the statement that some lakes are oceans, the overlapping part between lakes and oceans is also part of roads. Therefore, some oceans are definitely roads, so conclusion (I) logically follows.

For conclusion (II), statement 2 places all planets inside oceans, and statement 1 shows a partial overlap between lakes and oceans. Since both planets and lakes are contained in or overlap with oceans, there is no information forcing planets and lakes to intersect with each other. Thus, conclusion (II) does not follow.

Explanation

To find the required letters, we search for the pattern: Letter - Letter - Symbol.

Scanning the given series from left to right, in the group B - R - ©, the letter R is immediately preceded by the letter B and immediately followed by the symbol ©.

All other letters in the sequence fail to satisfy the condition: B is the first element and has no preceding character; W, S, Z, A, and L are immediately preceded by symbols; and I and O are immediately preceded by the symbol ©.

Therefore, only 1 letter (R) satisfies the given condition.

Explanation

The pattern followed by the given sets is: Second Number = (First Number × 4) - 1

Applying this to the given sets: (17 × 4) - 1 = 68 - 1 = 67 (22 × 4) - 1 = 88 - 1 = 87

Applying the same operation to 25: (25 × 4) - 1 = 100 - 1 = 99

Explanation

Tracking Sneha's movement along the horizontal (East-West) and vertical (North-South) axes relative to Point Q:

East-West displacement = +5 km (East) + 3 km (East) + 2 km (East) = 10 km East. North-South displacement = +7 km (North) - 7 km (South) = 0 km.

Since the vertical displacements cancel out completely, Sneha is at a net distance of 10 km towards the East from Point Q.

Explanation

Arranging the seven positions from top (1) to bottom (7):

Since three boxes are kept below T, T is at position 4. Only W is kept above O and two boxes are between T and W, which places W at position 1 and O at position 2. S is kept immediately below O, placing S at position 3. Since L is below P and above K, the remaining positions 5, 6, and 7 are occupied by P, L, and K respectively.

The complete arrangement from top to bottom is W, O, S, T, P, L, K. Between T (position 4) and L (position 6), there is 1 box (P).

Explanation

The pattern follows a sequential shift in the alphabetical positions of each letter: -1, +2, -3, and +4.

Applying this logic: T - 1 = S R + 2 = T K - 3 = H F + 4 = J

Applying these shifts yields STHJ.

Explanation

The pattern is based on subtracting 4, 3, 2, and 1 sequentially from the positional values of the four letters in the English alphabetical order.

For HEGK to DBEJ: H (8) - 4 = 4 (D) E (5) - 3 = 2 (B) G (7) - 2 = 5 (E) K (11) - 1 = 10 (J)

For ILNP to EILO: I (9) - 4 = 5 (E) L (12) - 3 = 9 (I) N (14) - 2 = 12 (L) P (16) - 1 = 15 (O)

Applying the same rule to FMRT: F (6) - 4 = 2 (B) M (13) - 3 = 10 (J) R (18) - 2 = 16 (P) T (20) - 1 = 19 (S)

Explanation

Replacing the letters with their respective mathematical operations gives:

25 ÷ 5 × 7 + 9 - 2

Applying the BODMAS rule:

Division: 25 ÷ 5 = 5 Multiplication: 5 × 7 = 35 Addition and Subtraction: 35 + 9 - 2 = 42

Explanation

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

81 - 1² = 80 80 - 2² = 76 76 - 3² = 67 67 - 4² = 51

Following this pattern, the next term is obtained by subtracting 5² from 51:

51 - 5² = 51 - 25 = 26

Explanation

The logic followed here is: Result = (Number + 2) × 10

For 6: (6 + 2) × 10 = 8 × 10 = 80 For 12: (12 + 2) × 10 = 14 × 10 = 140

Applying the same logic to 24: (24 + 2) × 10 = 26 × 10 = 260

Explanation

The standard pattern in this group is an increase of 3 positions in alphabetical order between consecutive letters (+3, +3). In ILN, the positional values are I (9), L (12), and N (14), which follow a pattern of +3 followed by +2, deviating from the common rule.

Explanation

Break down the given expression R + J @ K + C step by step:

R + J means R is the daughter of J. J @ K means J is the husband of K. This implies J and K are a married couple where J is male and K is female. K + C means K is the daughter of C.

Since R is the daughter of J, and J is married to K, J is R's father and K is R's mother. Therefore, K is the mother of R.

Explanation

From the given statements, all pigs are both cats and jackals. The common group of pigs creates an intersection between cats and jackals, which logically yields that some cats are jackals. Hence, conclusion (II) follows.

For conclusion (I), elephants are defined only as being part of cats, with no statement establishing a link between elephants and jackals. Therefore, conclusion (I) does not follow.

Explanation

To find the letters that are immediately preceded by another letter and immediately followed by a symbol, we look for the pattern: Letter + Letter + Symbol.

Analyzing the given series from left to right: O is preceded by start and followed by ? (Symbol). Q is preceded by ? (Symbol) and followed by ! (Symbol). R is preceded by ! (Symbol) and followed by + (Symbol). S is preceded by + (Symbol) and followed by - (Symbol). T is preceded by - (Symbol) and followed by a symbol. U is preceded by a symbol and followed by * (Symbol). V is preceded by * (Symbol) and followed by / (Symbol). A is preceded by / (Symbol) and followed by P (Letter). P is preceded by A (Letter) and followed by < (Symbol). W is preceded by < (Symbol) and followed by = (Symbol). X is preceded by = (Symbol) and followed by : (Symbol).

Only the letter P satisfies both conditions, being preceded by the letter A and followed by the symbol <. Thus, there is only ONE such letter.

Explanation

Each component of the cluster follows a constant pattern of change across the terms:

First letter: T (20) − 3 = Q (17), Q − 3 = N (14), N − 3 = K (11), K − 3 = H (8) Second letter: V (22) − 3 = S (19), S − 3 = P (16), P − 3 = M (13), M − 3 = J (10) Third letter: A (27) − 3 = X (24), X − 3 = U (21), U − 3 = R (18), R − 3 = O (15) Number: 7 + 3 = 10, 10 + 3 = 13, 13 + 3 = 16, 16 + 3 = 19

Combining the results yields HJO 19.

Explanation

The mathematical operations connecting the numbers in each set follow the rule: multiply by 2 to get the second number, add 10 to get the third number, and divide by 2 to get the fourth number.

In the given sets: 8 × 2 = 16, 16 + 10 = 26, 26 ÷ 2 = 13 5 × 2 = 10, 10 + 10 = 20, 20 ÷ 2 = 10

Applying this pattern: 12 × 2 = 24 24 + 10 = 34 34 ÷ 2 = 17

Explanation

The common letters in the words MEAT and TIME are M, E, and T. The common digits in their respective codes 5267 and 5362 are 5, 2, and 6. Therefore, the set of letters {M, E, T} corresponds to the set of digits {5, 2, 6} in some order.

In the word TIME, removing the common letters M, E, and T leaves the letter I. Similarly, removing the common digits 5, 2, and 6 from its code 5362 leaves the digit 3. Thus, the code for 'I' is 3.

Explanation

The differences between consecutive terms in the series follow the pattern of consecutive perfect squares:

22 - 21 = 1 = 1² 26 - 22 = 4 = 2² 35 - 26 = 9 = 3² 51 - 35 = 16 = 4²

Adding 5² = 25 to the last term gives 51 + 25 = 76.

Explanation

The series follows a dual pattern for the letters and the numbers:

First letters decrease by 3: L (12) → I (9) → F (6) → C (3) → Z (26) Second letters decrease by 3: E (5) → B (2) → Y (25) → V (22) → S (19) Third letters decrease by 3: V (22) → S (19) → P (16) → M (13) → J (10) Numbers increase by 4: 16 → 20 → 24 → 28 → 32

Combining these gives ZSJ 32.

Explanation

Let the seven positions from left to right be numbered 1 to 7.

Since four people sit to the right of S, S is at position 3. Three people sit between P and C, and B is immediately to the left of P. This places B at position 1, P at position 2, and C at position 6. R sits immediately to the right of Q, filling the adjacent empty spots at positions 4 and 5 respectively. O occupies the remaining position 7.

The final order from position 1 to 7 is B, P, S, Q, R, C, O.

With R at position 5 and O at position 7, exactly 1 person (C at position 6) sits between O and R.

Explanation

Arranging the seven people clockwise around the circular table facing the center:

Placing Q at position 1, S sits to the immediate right of Q at position 2.

Counting three positions counter-clockwise (to the left) from S places O at position 6.

C sits to the immediate right of R, and C sits second to the left of B. Placing this group into the open positions puts R at position 4, C at position 5, and B at position 7.

The remaining person P sits at position 3.

The complete clockwise seating order is Q, S, P, R, C, O, B. Counting four positions to the right (clockwise) from P brings us to B.

Explanation

The required pattern is Symbol - Number - Letter.

Checking all the single-digit numbers in the series from left to right: In G 6 E, 6 is preceded by letter G and followed by letter E. In # 3 D, 3 is preceded by symbol # and followed by letter D, which satisfies the given condition. In D 2 %, 2 is preceded by letter D and followed by symbol %. In % 7 4, 7 is preceded by symbol % and followed by number 4. In 7 4 Y, 4 is preceded by number 7 and followed by letter Y. In | 5 +, 5 is preceded by symbol | and followed by symbol +.

Only 1 number (3) satisfies both conditions simultaneously.

Explanation

Interchanging the signs and applying the BODMAS rule:

156 ÷ 12 + 13 × 8 - 71

Performing division first: 156 ÷ 12 = 13

Performing multiplication next: 13 × 8 = 104

Performing addition and subtraction: 13 + 104 - 71 = 117 - 71 = 46

Explanation

From statement I, Meena, Tanu, and Sunita sit together in the consecutive order Meena - Tanu - Sunita. This block of three people alone does not fix their exact seat numbers among the five positions.

From statement II, Kavita sits immediately to the left of Riya. Since Riya is at one of the ends, she must be at the extreme right end (5th position) and Kavita at the 4th position.

Combining both statements, seats 4 and 5 are occupied by Kavita and Riya respectively, which leaves seats 1, 2, and 3 for the block Meena - Tanu - Sunita. This uniquely places Sunita in the 3rd position, exactly in the middle of the row.

Explanation

The pattern follows an alternating addition of +2 and +3 to the alphabetical positions of each letter.

First letter: G (7) + 2 = 9 (I) Second letter: B (2) + 3 = 5 (E) Third letter: M (13) + 2 = 15 (O) Fourth letter: P (16) + 3 = 19 (S)

Applying this positional shift to GBMP yields IEOS.

Explanation

All carrots are contained within the set of peas, and no pea is a tomato. Since carrots are a subset of peas, no carrot can be a tomato, making Conclusion II logically valid. On the other hand, while all peas are onions, onions represent a broader category that can overlap with tomatoes outside the pea region, so Conclusion I does not necessarily follow.

Explanation

Since exactly two people live below C, C lives on floor 3. Since two people live between B and C, B must live on floor 6. A lives above E but below C, which means A lives on floor 2 and E lives on floor 1. F does not live above D, so F lives below D on the remaining empty floors, placing D on floor 5 and F on floor 4. The arrangement from top floor 6 to bottom floor 1 is B, D, F, C, A, E. Therefore, D lives on floor 5, directly below B.

Explanation

Decoding the given expression G - C + D # L % Q step by step:

G - C means G is the brother of C. C + D means C is the mother of D. D # L means D is the daughter of L. Since C is D's mother and D is L's daughter, C and L are married, making C the wife and L the husband. L % Q means L is the father of Q.

Since L is the father of Q and C is L's wife, C is the mother of Q. Since G is the brother of C, G is Q's mother's brother.

Explanation

By comparing the words 'NEAR' and 'GROW', the only letter common to both is 'R'. Similarly, comparing their respective code numbers '3519' and '8645', the only digit common to both is 5. Therefore, the letter 'R' is coded as 5.

Explanation

Applying the given operations to each digit of the number 4528173:

For even digits, subtract 2: 4 becomes 2 2 becomes 0 8 becomes 6

For odd digits, add 1: 5 becomes 6 1 becomes 2 7 becomes 8 3 becomes 4

The resulting number is 2606284.

In the new number, the digits 2 and 6 each appear twice, while 0, 8, and 4 appear only once. Thus, two digits appear more than once.

Explanation

We need to identify symbols in the series that satisfy the pattern: Number - Symbol - Letter.

Scanning the given series: Z Q Y 7 9 E D V Z R X 4 N G T B 3 X A T 4 H

The symbols present are: The first asterisk (): Preceded by number 7, but followed by number 9 (does not satisfy the condition). The second asterisk (): Preceded by number 4 and followed by letter N (satisfies the condition: Number - Symbol - Letter).

Thus, there is only one such symbol in the series.

Explanation

Since only Q lives above P, P lives on floor 5 and Q lives on floor 6. The remaining available floors for C, D, N, and O are 4, 3, 2, and 1.

To have exactly two people between C and N, they must be placed on floors 4 and 1. Since C lives on an odd-numbered floor, C lives on floor 1, which is the bottommost floor, while N lives on floor 4. The remaining floors 3 and 2 are occupied by O and D respectively, satisfying the condition that O lives immediately above D.

Explanation

In the pair LO-PS, the letters of the second cluster are obtained by shifting each letter of the first cluster forward by 4 positions in the alphabetical order (L + 4 = P and O + 4 = S). The other pairs in the group follow a pattern where each letter is shifted forward by only 1 position.

Explanation

Let Point A be located at coordinates (0, 0).

Movement 1: 47 km South brings Sharad to (0, -47). Movement 2: Turning right (West) and driving 49 km brings him to (-49, -47). Movement 3: Turning right (North) and driving 51 km brings him to (-49, 4). Movement 4: Turning right (East) and driving 53 km brings him to (4, 4). Movement 5: Turning right (South) and driving 4 km brings him to Point P at (4, 0).

Since Point P is located at (4, 0) and Point A is at (0, 0), Point P is 4 km East of Point A. To travel from Point P back to Point A, he needs to drive 4 km to the West.

Explanation

Decoding the given relationship expression step-by-step: S × R means S is the brother of R. R - U means R is the daughter of U. U + N means U is the husband of N, which makes N the mother of R and S. N + M means N is the sister of M.

Since N is the sister of M, and S is the son of N, S is M's sister's son.

Explanation

The floor arrangement from top to bottom (floors 6 to 1) is determined as follows:

B lives on the topmost floor, Floor 6. Three people live between B and D, which places D on Floor 2. F lives immediately above A and immediately below E, meaning E, F, and A occupy three consecutive floors in that order. The only three consecutive vacant floors are 5, 4, and 3. Thus, Floor 5 is E, Floor 4 is F, and Floor 3 is A. The remaining floor, Floor 1, is occupied by C.

The full arrangement from Floor 6 to Floor 1 is B, E, F, A, D, C. Between F on Floor 4 and C on Floor 1, there are two people: A (Floor 3) and D (Floor 2).
