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

Explanation

In the rule followed by the group, each consecutive letter is obtained by subtracting 3 from the alphabetical position of the preceding letter. For URQ, the alphabetical positions are U = 21, R = 18, and Q = 17. The position difference between U and R is -3 (21 - 3 = 18), but between R and Q it is -1 (18 - 1 = 17) instead of -3, breaking the uniform gap of 3.

Explanation

Among the given set of numbers (412, 368, 457, 283, 396):

Highest number = 457 Third digit of 457 = 7

Lowest number = 283 Second digit of 283 = 8

Sum = 7 + 8 = 15

Explanation

Statement I gives the order Charu > Bhavna > Anita. Statement II gives the order Bhavna > Deepa > Anita. Combining both statements establishes that Charu > Bhavna > Deepa > Anita. However, neither statement provides any information about Esha's relative position. Esha could have scored less than Anita or more than Anita, making it impossible to uniquely determine who scored the lowest marks even when using both statements together.

Explanation

The series follows distinct logic for the numbers and the positions of the letters in the English alphabet.

The numerical part increases by 11 in each step: 11, 22, 33, 44, giving 44 + 11 = 55.

For the first letter of each cluster, the positional values alternate between subtracting 11 and adding 15: L(12) − 11 = A(1), A(1) + 15 = P(16), P(16) − 11 = E(5), and E(5) + 15 = 20, which is T.

For the second letter, the positional values alternate between adding 15 and subtracting 11: E(5) + 15 = T(20), T(20) − 11 = I(9), I(9) + 15 = X(24), and X(24) − 11 = 13, which is M.

For the third letter, the pattern also alternates between adding 15 and subtracting 11: F(6) + 15 = U(21), U(21) − 11 = J(10), J(10) + 15 = Y(25), and Y(25) − 11 = 14, which is N.

Combining the resulting letters and number gives TMN 55.

Explanation

The general rule for the group is a letter position shift of -4 followed by +2. In MIL, the letter positions are M = 13, I = 9, and L = 12. The shift from M to I is -4 (13 - 4 = 9), but the shift from I to L is +3 (9 + 3 = 12), deviating from the pattern.

Explanation

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

For the letter positions, each letter moves backwards by 2 alphabetical places (subtract 2 from their positional values): First letter: M(13) - 2 = K(11), K(11) - 2 = I(9), I(9) - 2 = G(7), G(7) - 2 = E(5) Second letter: P(16) - 2 = N(14), N(14) - 2 = L(12), L(12) - 2 = J(10), J(10) - 2 = H(8) Third letter: L(12) - 2 = J(10), J(10) - 2 = H(8), H(8) - 2 = F(6), F(6) - 2 = D(4)

For the numbers, each term increases by 8: 79 + 8 = 87 87 + 8 = 95 95 + 8 = 103 103 + 8 = 111

Combining the letters and the number gives EHD 111.

Explanation

The pattern followed in the given sets is: Second number = First number + Third number + 1

Applying this formula to the given sets: 9 + 7 + 1 = 17 6 + 5 + 1 = 12

Applying the same rule: 4 + 4 + 1 = 9

Explanation

Comparing the letters in 'LITE' and 'TIME', the three common letters are I, T, and E. Comparing their respective code digit sets {3, 4, 9, 2} and {3, 9, 5, 4}, the three common digits are 3, 4, and 9.

The letter 'M' is the only letter in 'TIME' that does not appear in 'LITE', and 5 is the only digit in the code for 'TIME' that does not appear in the code for 'LITE'. Therefore, the code for 'M' is 5.

Explanation

Numbering the positions from left to right as 1 to 7:

Q sits second from the left end, placing Q at position 2. Since two people sit between Q and R, R is at position 5. Only one person sits between R and S, placing S at position 3, because placing S at position 7 leaves no room for C to sit to its right. C sits immediately to the right of S, placing C at position 4. O sits immediately to the left of B, so O and B occupy adjacent positions 6 and 7, respectively. The remaining position 1 is occupied by P.

The complete order from left to right is P, Q, S, C, R, O, B. Between P at position 1 and O at position 6, there are 4 people: Q, S, C, and R.

Explanation

Substituting the respective mathematical operators into the given expression yields: 19 - 54 ÷ 6 + 4 × 2

Applying the BODMAS rule for the order of mathematical operations:

First, perform division: 54 ÷ 6 = 9 The expression becomes: 19 - 9 + 4 × 2

Next, perform multiplication: 4 × 2 = 8 The expression becomes: 19 - 9 + 8

Finally, perform subtraction and addition from left to right: 19 - 9 = 10 10 + 8 = 18

Explanation

Removing all the symbols from the series leaves only the numbers from left to right: 8, 6, 2, 1, 5, 9, 7, 5, 3, 1, 4.

Counting six digits from the right end: 4 is the first, 1 is the second, 3 is the third, 5 is the fourth, 7 is the fifth, and 9 is the sixth.

Explanation

A and D are married, making A the mother of their son M. Since Y is married to M, Y is the wife of M. Therefore, Y is A's son's wife.

Explanation

From the given statements, all baboons are chimpanzees and some monkeys are baboons, which guarantees that some chimpanzees are monkeys. However, this does not imply that all chimpanzees are monkeys, so conclusion (I) does not follow.

Further, there is no direct or indirect relation specified between gorillas and baboons or chimpanzees. Gorillas and chimpanzees can be completely disjoint sets while still satisfying all the given statements, so conclusion (II) does not follow either.

Explanation

The difference between consecutive terms follows the sequence of prime numbers:

37 - 35 = 2 40 - 37 = 3 45 - 40 = 5 52 - 45 = 7

The next prime number in the sequence is 11. Adding 11 to the last term yields 52 + 11 = 63.

Explanation

The letter-cluster pairs follow a uniform pattern where each letter in the first cluster is shifted backward by 1 position (-1) in the alphabetical order to form the second cluster.

Applying this rule to the first pair with # = LRN: L - 1 = K R - 1 = Q N - 1 = M

Applying the same rule to the second pair with % = NTP: O - 1 = N U - 1 = T Q - 1 = P

Both pairs maintain the identical -1 positional shift for all three letters.

Explanation

Each letter in the cluster decreases by 2 positions in alphabetical order, while the number increases by 6 in each step:

First letter: A (27) - 2 = Y (25), Y - 2 = W (23), W - 2 = U (21), U - 2 = S (19) Second letter: I (9) - 2 = G (7), G - 2 = E (5), E - 2 = C (3), C - 2 = A (1) Third letter: W (23) - 2 = U (21), U - 2 = S (19), S - 2 = Q (17), Q - 2 = O (15) Number: 8 + 6 = 14, 14 + 6 = 20, 20 + 6 = 26, 26 + 6 = 32

Combining these gives SAO 32.

Explanation

By comparing the two given words, 'NICE' and 'COST', the only common letter is 'C'. Comparing their respective numerical codes '8246' and '3851', the only digit present in both is '8'. Therefore, the code for 'C' is 8.

Explanation

Numbering the positional order of the letters in the first word as 1-2-3-4:

The second word rearranges the letters in the order 1-3-4-2. The third word rearranges the letters in the order 3-2-1-4.

Applying this pattern to MASK (1=M, 2=A, 3=S, 4=K): Position order 1-3-4-2 gives MSKA. Position order 3-2-1-4 gives SAMK.

Explanation

Taking Point A as the origin (0, 0):

Net East-West displacement = -53 (West) + 54 (East) - 1 (West) = 0 km. Net North-South displacement = -50 (South) + 60 (North) = +10 km (North).

Point P is located 10 km North of Point A. To reach Point A from Point P, Golu needs to travel 10 km to the South.

Explanation

Interchanging + with -, - with +, × with ÷, and ÷ with ×, the given equation becomes:

95 × 5 - 378 ÷ 3 + 161 = ?

Applying the BODMAS rule:

First, perform division: 378 ÷ 3 = 126

Next, perform multiplication: 95 × 5 = 475

Finally, perform subtraction and addition from left to right: 475 - 126 + 161 = 349 + 161 = 510

Explanation

The pattern followed by the given letter pairs is a position-shift of -2, +5, and -2 for the three respective letters in alphabetical order.

For DRU → BWS: D - 2 = B R + 5 = W U - 2 = S

For ZBQ → XGO: Z - 2 = X B + 5 = G Q - 2 = O

Applying the same (-2, +5, -2) shift to VLM: V - 2 = T L + 5 = Q M - 2 = K

Explanation

The week runs from Monday to Sunday in seven consecutive days. V has an exam on Thursday. Since R has an exam after V, Q after R, and S after Q, the group R, Q, and S must take their exams in that relative order after Thursday.

As there are exactly three days remaining after Thursday (Friday, Saturday, and Sunday), these days are uniquely filled by R on Friday, Q on Saturday, and S on Sunday. The remaining three days before Thursday (Monday, Tuesday, and Wednesday) are filled by P, T, and U respectively, following the order P < T < U.

Explanation

The available floors are 1, 2, 3, 4, 5, and 6.

Since the product of the floor numbers of D and B is 15, the only possible floor numbers for D and B are 3 and 5 in some order.

The sum of C and B's floor numbers is 7. If B were on floor 5, C would be on floor 2, leaving floors 1, 4, and 6 vacant. Since no two available floors would be consecutive, A could not be placed immediately above F.

Thus, B is on floor 3, which means D is on floor 5 and C is on floor 4.

The remaining vacant floors are 1, 2, and 6. Since A lives immediately above F, F lives on floor 1 and A lives on floor 2.

The sum of the floor numbers of B and F is 3 + 1 = 4.

Explanation

The rule governing the pattern in the given sets is: Second number = First number × 4 Third number = Second number × 3 Fourth number = Third number × 2

In the given sets: 5 × 4 = 20, 20 × 3 = 60, 60 × 2 = 120 8 × 4 = 32, 32 × 3 = 96, 96 × 2 = 192

Applying the same sequential operations: 10 × 4 = 40 40 × 3 = 120 120 × 2 = 240

Explanation

Removing non-letter characters from the given series leaves the sequence C, E, T, R, B, D, Z, R, O, K. Counting from the left end, the first letter is C, the second is E, the third is T, and the fourth letter is R.

Explanation

In BD-FH, the alphabetical positions of the letters are B (2), D (4), F (6), and H (8). The difference between every consecutive letter, including the transition between the two clusters (D to F), is +2. This deviates from the common pattern where the gap between the second and third letters is +1.

Explanation

To find the required symbols, we search for the pattern where a symbol is placed directly between two single-digit numbers: Number → Symbol → Number.

Scanning the series from left to right, the symbol < positioned between 5 and 3 is immediately preceded by the number 5 and immediately followed by the number 3.

Thus, there is 1 such symbol that satisfies both conditions.

Explanation

Combining Statement 1 (All hands are legs) and Statement 2 (Some hands are ears) shows that the hands that are ears are also legs. Therefore, some legs are definitely ears, making Conclusion I valid. Statement 2 (Some hands are ears) and Statement 3 (Some ears are arms) are both particular statements, which cannot be combined to establish a definite relation between hands and arms, so Conclusion II does not follow.

Explanation

Placing the seven individuals in counter-clockwise order around the table representing the right direction:

Starting with U at position 1, G sits third to the right at position 4. Since G sits to the immediate right of H, H is at position 3. Counting three people to the right of H (positions 4, 5, and 6), F is placed at position 7. V sits to the immediate right of W, which obliges W to be at position 5 and V at position 6. The remaining position 2 is occupied by I.

Counting two positions to the right of I (at position 2) leads to position 4, where G is seated.

Explanation

Decoding the expression T @ S % G + H | K step-by-step from right to left:

H | K means H is the father of K. G + H means G is the wife of H, making G the mother of K. S % G means S is the brother of G, making S the brother of K's mother (maternal uncle). T @ S means T is the son of S, making T the son of K's mother's brother.

Therefore, T is K's mother's brother's son.

Explanation

From statement I, Ketan > Mayank > Harsh. From statement II, Mayank > Rohit > Harsh. Combining both statements gives the partial order Ketan > Mayank > Rohit > Harsh. However, neither statement provides any information about Sidharth's height, who could be shorter than Harsh or taller than any of the others. Without knowing Sidharth's relative position among the five individuals, the shortest person cannot be uniquely determined.

Explanation

The exam schedule from Monday to Sunday is determined step-by-step:

Since only G has an exam before K, G is scheduled for Monday (1st day) and K for Tuesday (2nd day).

With three people between K and H, H is scheduled for Saturday (6th day).

Only three people are between L and J, so their days must differ by 4. The available positions are Wednesday (3rd day) and Sunday (7th day). Since E has an exam before J and after F, J must be on Sunday and L must be on Wednesday.

The remaining days, Thursday (4th day) and Friday (5th day), are assigned to F and E, respectively.

Since L's exam is on Wednesday, exactly two people, G and K, have exams before L.

Explanation

The pattern in the series is obtained by adding increasing multiples of 3 to each consecutive term:

23 + 3 = 26 26 + 6 = 32 32 + 9 = 41 41 + 12 = 53

Following this sequence of differences (3, 6, 9, 12, 15), the next term is 53 + 15 = 68.

Explanation

Deconstructing the expression step by step from right to left to trace the relationship with respect to G:

K ÷ G means K is the father of G. R + K means R is the son of K, which means R is G's brother. O × R means O is the wife of R, which makes O G's brother's wife. W - O means W is the brother of O.

Since O is G's brother's wife and W is O's brother, W is G's brother's wife's brother.

Explanation

The pattern follows the logic n × (n + 2).

For 10: 10 × (10 + 2) = 10 × 12 = 120

For 12: 12 × (12 + 2) = 12 × 14 = 168

Applying the same formula to 18: 18 × (18 + 2) = 18 × 20 = 360

Explanation

X lives on an even-numbered floor other than floor 4, placing X on either floor 6 or floor 2.

If X is on floor 6, then T must be on floor 3 so that two people live between them. S lives on an odd-numbered floor other than floor 1, so S must be on floor 5. Z lives immediately below S, placing Z on floor 4. Since two people live between S and Y, Y must be on floor 2. The remaining person, U, occupies floor 1.

If X were on floor 2, T would be on floor 5, forcing S to floor 3 and Z to floor 2, which contradicts X being on floor 2.

Thus, the floor arrangement from top (6) to bottom (1) is X, S, Z, T, Y, U. With Z on floor 4 and U on floor 1, the two people living between them are Y and T.

Explanation

Comparing the two words 'WINS' and 'NORM', the only common letter is 'N'. Similarly, in their respective codes '8246' and '3851', the only common digit is '8'. Thus, 'N' is coded as 8.

Explanation

The digit second from the left in the original number 8371456 is 3. Since 3 is an odd digit, adding 1 gives 3 + 1 = 4.

The digit second from the right in the original number is 5. Since 5 is an odd digit, adding 1 gives 5 + 1 = 6.

The sum of these two new digits is 4 + 6 = 10.

Explanation

The series follows two distinct patterns for the letter cluster and the number:

Letter Pattern: Each letter in the cluster shifts backward by 6 positions in alphabetical order: First letters: Y (25) - 6 = S (19) - 6 = M (13) - 6 = G (7) - 6 = A (1) Second letters: Q (17) - 6 = K (11) - 6 = E (5) - 6 = Y (25) - 6 = S (19) Third letters: M (13) - 6 = G (7) - 6 = A (1) - 6 = U (21) - 6 = O (15)

Number Pattern: The numbers follow n × (n + 1) for n = 1, 2, 3, 4, 5: 1 × 2 = 2 2 × 3 = 6 3 × 4 = 12 4 × 5 = 20 5 × 6 = 30

Combining the letter cluster and number gives ASO 30.

Explanation

In the English alphabetical series, the letter clusters in the group follow a pattern where the second letter is 3 positions ahead of the first, and the third letter is 2 positions ahead of the second (+3, +2).

For DGH, the letter positions are D = 4, G = 7, and H = 8. The difference between D and G is +3, but the difference between G and H is only +1, making its pattern +3, +1.

Explanation

Comparing the word 'MINT' coded as '6134' and 'TIME' coded as '4365', the letters common to both words are M, I, and T. The digits common to both codes are 6, 3, and 4. In the word 'TIME', the remaining letter is 'E' and the remaining digit in its code is 5, which means 'E' is represented by the digit 5.

Explanation

Numbering seven positions around the table in clockwise order (which corresponds to the right direction for a person facing the centre):

Placing P at position 1: Two people sit between P and U to the right of P, placing U at position 4. Three people sit between P and T, placing T at position 5. Two people sit between U and V, placing V at position 7. S sits to the immediate left of R (counter-clockwise), occupying the adjacent free positions 2 and 3, so S is at position 2 and R is at position 3. The remaining position 6 is occupied by Q.

Counting from the right of Q (position 6) clockwise to P (position 1), only V at position 7 sits between them, making a total of 1 person.

Explanation

Taking Point A as the origin (0, 0):

Driving 42 km West reaches (-42, 0). Turning left (South) for 40 km reaches (-42, -40). Turning left (East) for 49 km reaches (-42 + 49, -40) = (7, -40). Turning left (North) for 46 km reaches (7, -40 + 46) = (7, 6). Turning left (West) for 7 km reaches (7 - 7, 6) = (0, 6), which is Point P.

To reach Point A (0, 0) from Point P (0, 6), Fardin needs to travel 6 km directly South along the vertical axis.

Explanation

The seven days from Monday to Sunday correspond to the sequence of exams. B is assigned to Monday. Placing three exams between B and L puts L on Friday. Since N is on Sunday and one exam is scheduled between L and A, A is assigned to Wednesday. The remaining open days are Tuesday, Thursday, and Saturday. The condition that S takes the exam after I and before G requires the order I, S, and G, assigning I to Tuesday, S to Thursday, and G to Saturday.

Explanation

From statement I, since N is shorter than only three trees out of five, N is in the fourth position from the tallest (second shortest). Statement I alone does not identify the shortest tree.

From statement II, N is taller than M (N > M), but this alone does not reveal the positions of L and V.

Combining both statements, N is in the fourth position and is taller than M. Since only one position remains below N (the fifth position), M must occupy the fifth position. This uniquely identifies M as the shortest tree.

Explanation

The given three-digit numbers are 419, 975, 573, 389, and 937.

The highest number is 975, and its second digit is 7. The lowest number is 389, and its third digit is 9.

Summing the second digit of the highest number and the third digit of the lowest number gives 7 + 9 = 16.

Explanation

The statements form a sequential chain of set inclusion: Skin ⊆ Hair ⊆ Fur ⊆ Fleece.

Since skin is entirely contained within hair, which is within fur, which is within fleece, all skin is contained within fleece, making Conclusion (I) logically valid.

Furthermore, since all hair is contained within fleece, converting this universal affirmative relationship confirms that a portion of fleece is hair, making Conclusion (II) logically valid.

Explanation

We need to find letters that fit the pattern: Symbol - Letter - Letter.

Scanning the given series from left to right for this pattern: A G (letter A is preceded by symbol # and followed by letter G) % B H (letter B is preceded by symbol % and followed by letter H)

• D F (letter D is preceded by symbol + and followed by letter F) ! L M (letter L is preceded by symbol ! and followed by letter M)

There are 4 such letters (A, B, D, and L).

Explanation

Each letter advances by +5 positions in alphabetical order (wrapping from Z to A): First letter: K (+5) → P (+5) → U (+5) → Z (+5) → E Second letter: U (+5) → Z (+5) → E (+5) → J (+5) → O Third letter: O (+5) → T (+5) → Y (+5) → D (+5) → I

The numerical part increases by +7 in each successive term: 5 (+7) → 12 (+7) → 19 (+7) → 26 (+7) → 33

Combining the letters and the number gives EOI 33.

Explanation

The given series follows a pattern where consecutive square numbers are added to each term: 77 + 1² = 78 78 + 2² = 82 82 + 3² = 91 91 + 4² = 107 107 + 5² = 132
