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

Explanation

For seven people sitting around a circular table facing the center, clockwise motion represents the left direction and counter-clockwise motion represents the right direction.

Placing R at position 1, C being an immediate neighbor of both R and S places C at position 2 and S at position 3 clockwise. P sitting third to the left (clockwise) of S places P at position 6. Counting one person between P and R from the right (counter-clockwise) of R confirms P is two positions to the right of R at position 6. Placing O third to the left of B requires B to be at position 4 and O at position 7. The remaining person Q takes position 5.

The complete clockwise arrangement of positions 1 through 7 is R, C, S, B, Q, P, O. Counting from the right of Q (counter-clockwise) to C passes through B and S, meaning exactly two people sit between Q and C.

Explanation

In the standard pattern, the second letter within each cluster is obtained by subtracting 4 positions from the first letter, and the letters of the second cluster are obtained by subtracting 5 positions from the corresponding letters of the first cluster. In BX-VU, the difference between V and U is 1 position (V - 1 = U) instead of 4, and subtracting 5 positions from B (position 28) and X (position 24) yields WS instead of VU.

Explanation

Each letter in the letter-cluster advances by 7 positions in the alphabetical series: the first letters follow G → N → U → B → I (+7), the second letters follow H → O → V → C → J (+7), and the third letters follow B → I → P → W → D (+7). The number part decreases by 1 in each successive term (10 → 9 → 8 → 7 → 6). Combining these gives IJD 6.

Explanation

The given set of numbers is 351, 417, 211, 159, and 294.

The highest number in the set is 417, which has 1 as its second digit. The lowest number in the set is 159, which has 9 as its third digit.

Adding these two digits gives 1 + 9 = 10.

Explanation

Combining "Some cats are monkeys" and "All monkeys are donkeys" establishes that at least some cats are donkeys, which does not guarantee that all cats are donkeys. Similarly, both horses and monkeys are subsets of donkeys, but without a direct statement linking horses and monkeys, their set intersection cannot be determined. Consequently, neither conclusion logically follows from the given statements.

Explanation

The pattern followed by the numbers in the given sets (A, B, C) is: B = A² - C

Applying this rule to the given sets: 37² - 8 = 1369 - 8 = 1361 47² - 24 = 2209 - 24 = 2185

Similarly, applying the same pattern to (12, 141, 3): 12² - 3 = 144 - 3 = 141

Explanation

The pattern in the series involves adding consecutive multiples of 4 to each term:

10 + 4 = 14 14 + 8 = 22 22 + 12 = 34 34 + 16 = 50 50 + 20 = 70

Following this sequence, adding 20 to the last term yields 70.

Explanation

D visited the mall on Tuesday. Since two people visited between B and D, B must have visited on Friday. C visited immediately before F, which means C and F occupy two consecutive days; the only adjacent open days are Wednesday and Thursday, placing C on Wednesday and F on Thursday. A did not visit on Saturday, placing A on Monday and E on Saturday. Thus, C visited the mall on Wednesday.

Explanation

The pattern followed in both pairs is a constant backward shift of 2 positions (-2) for each letter in the alphabetical order.

For the first pair, PTN shifts to NRL: P (-2) = N T (-2) = R N (-2) = L

For the second pair, GKE shifts to EIC: G (-2) = E K (-2) = I E (-2) = C

Explanation

The given statements establish that all malls are contained within halls, which in turn are contained within walls. The statement that no mall is a fall only restricts the set of malls from overlapping with falls.

Conclusion I does not follow because the portion of halls outside of malls can still overlap with falls. Conclusion II does not follow because the portion of walls outside of malls can also overlap with falls.

Explanation

Comparing the given words 'CAST' and 'SIDE', the only common letter present in both words is 'S'. Similarly, comparing their respective numerical codes '3519' and '8645', the only common digit present in both codes is '5'. Therefore, the letter 'S' is coded as '5'.

Explanation

The series follows a clear pattern of decreasing by 5 for both the letter positions and the numbers:

For the letters, each corresponding letter moves backward by 5 positions in the English alphabet: First letter: M (13) - 5 = H (8), H - 5 = C (3), C - 5 = X (24), X - 5 = S (19) Second letter: P (16) - 5 = K (11), K - 5 = F (6), F - 5 = A (1), A - 5 = V (22) Third letter: W (23) - 5 = R (18), R - 5 = M (13), M - 5 = H (8), H - 5 = C (3)

For the numbers, each value decreases by 5: 30 - 5 = 25, 25 - 5 = 20, 20 - 5 = 15, 15 - 5 = 10

Combining the resulting letters and number gives SVC 10.

Explanation

The pattern followed in each element of the series is:

First letter decreases by 1 in alphabetical position: H → G → F → E → D.

Second letter decreases by 2 in alphabetical position: A → Y → W → U → S.

Third letter decreases by 3 in alphabetical position: K → H → E → B → Y.

Number increases by 3 in each step: 8 → 11 → 14 → 17 → 20.

Applying this pattern to the last given term EUB 17 gives DSY 20.

Explanation

Floor numbers range from 1 to 6.

Given C + D = 3 and C lives on an even-numbered floor (2 or 4), C must be on floor 2, which means D lives on floor 1.

Since F + C = 7 and C = 2, F lives on floor 5.

B lives immediately above E, requiring two adjacent unoccupied floors. The remaining empty floors are 3, 4, and 6, so E lives on floor 3 and B lives on floor 4.

The remaining person A lives on floor 6.

With B on floor 4, the people living above B are F on floor 5 and A on floor 6, making a total of 2 people.

Explanation

Decoding the given expression step-by-step:

L % R means L is the father of R. R - K means R is the brother of K, which means L is also the father of K. K + V means K is the mother of V (a female), making K the daughter of L. V # E means V is the daughter of E (a female), which confirms V is the daughter of K.

Since V is the daughter of K, and K is the daughter of L, V is L's daughter's daughter.

Explanation

To satisfy the given criteria, a symbol must follow the pattern: Odd Number - Symbol - Non-Even Element (where the following element can be an odd number or a symbol, but not an even number).

The single-digit odd numbers are 1, 3, 5, 7, 9, and the even numbers are 0, 2, 4, 6, 8.

Evaluating the symbols preceded by an odd number: @ is preceded by 1 (odd) but followed by 4 (even), failing the second condition.

• is preceded by 9 (odd) and followed by 5 (odd), satisfying both conditions. ? is preceded by 5 (odd) and followed by ) (symbol), satisfying both conditions.

• is preceded by 7 (odd) and followed by = (symbol), satisfying both conditions.

The three symbols meeting both conditions are +, ?, and *.

Explanation

From statement I, since M is taller than only two trees, M is the 3rd tallest tree (_ > _ > M > _ > _). T is immediately taller than N, so the pair TN must occupy either positions 1 and 2 or positions 4 and 5.

Statement II states that V is taller than N, which alone provides no specific ranking for all trees.

Combining both statements, if TN occupies positions 4 and 5, the positions are _ > _ > M > T > N. The remaining trees L and V must occupy the top two positions. Since V is taller than N, both orders L > V > M > T > N and V > L > M > T > N satisfy all conditions. Because either L or V can be the tallest tree, both statements together are not sufficient to determine the answer.

Explanation

To find the required count, we search for the pattern Number - Symbol - Number in the given sequence:

1 % 5 / 9 9 / + 7 # 6 9 6 @ + 7 ? +

Checking the symbols in order from left to right: In the combination 5 / 9, the symbol / is preceded by the number 5 and followed by the number 9.

No other symbol in the sequence is both preceded and followed by a number, giving a total of only 1 such symbol.

Explanation

Labeling the letter positions in the base four-letter word from left to right as 1, 2, 3, and 4, the pattern transforms the base word into:

Second word: positions 3-4-1-2 Third word: positions 3-1-4-2

Applying this rule to LION (L=1, I=2, O=3, N=4): Positions 3-4-1-2 yield ONLI. Positions 3-1-4-2 yield OLNI.

Explanation

Since there are four people between C and D on a six-story building, C and D must occupy floors 1 and 6. Because E lives above C, C is on floor 1 and D is on floor 6.

F lives on an even-numbered floor other than floor 2, and floor 6 is occupied, placing F on floor 4.

B lives immediately above E. The only remaining adjacent empty floors are 3 and 2, so B is on floor 3 and E is on floor 2.

The remaining floor 5 is occupied by A. With A on floor 5, only one person (D on floor 6) lives above A.

Explanation

In categorical logic, a chain of particular statements ("Some A are B" and "Some B are C") does not establish any definite overlap between the first and third terms (A and C).

In conclusion (I), pillows and quilts are connected via blankets through two particular premises. Since the portion of blankets that are pillows may be entirely distinct from the portion of blankets that are quilts, no definite relationship exists between pillows and quilts.

In conclusion (II), blankets and curtains are connected via quilts through two particular premises. The portion of quilts that are blankets may be entirely separate from the portion of quilts that are curtains, so no definite relationship exists between blankets and curtains.

Explanation

The pattern in the given series follows the subtraction of consecutive perfect squares:

91 - 1² = 90 90 - 2² = 86 86 - 3² = 77 77 - 4² = 61 61 - 5² = 36

Subtracting 25 (5²) from 61 gives 36.

Explanation

The pattern followed in the given sets is: Third number = First number + (3 × Second number)

For the first set (11, 18, 65): 11 + (3 × 18) = 11 + 54 = 65

For the second set (5, 1, 8): 5 + (3 × 1) = 5 + 3 = 8

Applying the same pattern to (7, 12, 43): 7 + (3 × 12) = 7 + 36 = 43

Explanation

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

B has four people to his left, so B is at position 5. Three people sit between B and C, placing C at position 1. P sits immediately to the right of C, so P is at position 2. P and O are immediate neighbors of S, which places S at position 3 and O at position 4. R sits immediately to the left of Q, placing R at position 6 and Q at position 7.

The complete arrangement from left to right is C, P, S, O, B, R, Q. Since O is at position 4, exactly three people (C, P, S) sit to the left of O.

Explanation

The pattern followed by the letter clusters in the group is +4 for the second letter and +3 for the third letter based on alphabetical position (G + 4 = K, K + 3 = N; T + 4 = X, X + 3 = A; W + 4 = A, A + 3 = D). DHL deviates from this pattern as the positional values advance by +4 and +4 (D + 4 = H, H + 4 = L).

Explanation

Number seven positions 1 to 7 in clockwise order around the circle. Since everyone faces the centre, clockwise corresponds to the left and counter-clockwise corresponds to the right.

Placing H at position 1, G sits third to the left (3 steps clockwise) of H at position 4. F sits second to the left (2 steps clockwise) of G at position 6. F is to the immediate right of I, placing I at position 7. V sits third to the left (3 steps clockwise) of I at position 3. Since X is not an immediate neighbour of V, X cannot be at position 2 or 4, placing X at position 5 and W at position 2.

The clockwise order of positions 1 through 7 is H, W, V, G, X, F, and I. Moving 4 steps counter-clockwise (fourth to the right) from W at position 2 leads to position 5, where X sits.

Explanation

By comparing the two words 'MELT' (coded as 5431) and 'TIME' (coded as 7153), the letters M, E, and T are common to both words. Correspondingly, the digits 1, 3, and 5 are common to both codes.

The letter 'I' appears only in 'TIME', and the digit 7 appears only in its code '7153'. Therefore, the code for 'I' is 7.

Explanation

Since all rats are contained within the category of moles, and no mole can be a frog, it directly follows that no rat can be a frog either. Thus, conclusion (I) logically follows. Conclusion (II) does not follow because the given statements establish no definite relation between donkeys and frogs.

Explanation

Taking Point A as the origin (0, 0) on a Cartesian plane:

Driving 25 km south leads to (0, -25). Turning left (east) and driving 22 km leads to (22, -25). Turning left (north) and driving 10 km leads to (22, -15). Turning left (west) and driving 10 km leads to (12, -15). Turning right (north) and driving 15 km leads to Point P at (12, 0).

Since Point P is located 12 km to the east of Point A, driving from Point P to reach Point A requires traveling 12 km towards west.

Explanation

Decoding the relationship expression step-by-step from right to left:

H ÷ J means H is the father of J. G × H means G is the wife of H, which makes G the mother of J. F - G means F is the brother of G, which makes F the mother's brother (maternal uncle) of J. D + F means D is the daughter of F.

Combining these relations, D is the daughter of F, who is the brother of J's mother G. Therefore, D is J's mother's brother's daughter.

Explanation

Write the original sequence of digits and compare it position by position with the digits arranged in ascending order from left to right:

Original: 9 2 3 7 5 6 1 Sorted: 1 2 3 5 6 7 9

Comparing each position: 1st position: 9 and 1 2nd position: 2 and 2 (unchanged) 3rd position: 3 and 3 (unchanged) 4th position: 7 and 5 5th position: 5 and 6 6th position: 6 and 7 7th position: 1 and 9

The positions of 2 digits (2 and 3) remain unchanged.

Explanation

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

82 - 2 = 80 80 - 3 = 77 77 - 5 = 72 72 - 7 = 65

The next prime number after 7 is 11. Subtracting 11 from 65 gives 65 - 11 = 54.

Explanation

U is placed on floor 4. Two people live between U and Z, which forces Z to floor 1 because there are only two floors above floor 4. X lives immediately below U, placing X on floor 3. Since floor 3 is occupied by X, the condition that only T lives between U and Y requires T to be on floor 5 and Y on floor 6.

Explanation

The pattern follows the relation n × 24 = result:

5 × 24 = 120 4 × 24 = 96

Applying the same operation to 6: 6 × 24 = 144

Explanation

To find the symbols that are immediately preceded by a letter and immediately followed by a letter, we check the pattern Letter–Symbol–Letter in the given sequence:

C S L Q P Q L C E * / M H W J A N W J Z

Symbol *: Preceded by letter E, but followed by symbol /. Symbol /: Preceded by symbol *, followed by letter M. Symbol: Preceded by letter W and followed by letter J.

Only 1 symbol () satisfies the given condition.

Explanation

The fourth digit from the left in the original number 7843156 is 3. Since 3 is an odd digit, applying the given rule of adding 1 to each odd digit yields 3 + 1 = 4.

Explanation

The relationship between the numbers in each set follows the pattern: Second Number - First Number = Third Number

In the given sets: 20 - 18 = 2 48 - 47 = 1

Applying the same pattern: 45 - 27 = 18

Explanation

The pattern follows adding positional increments of +4, +2, +4, +2 to the letters of the given word based on their alphabetical positions:

L (+4) = P, I (+2) = K, N (+4) = R, O (+2) = Q B (+4) = F, Q (+2) = S, D (+4) = H, W (+2) = Y

Applying the same logic to NWPC: N (+4) = R W (+2) = Y P (+4) = T C (+2) = E

This gives RYTE.

Explanation

Representing the statements in terms of set relationships, Tigers ⊆ Wolves, Jackals ⊆ Wolves, and Animals ⊆ Wolves. This establishes that tigers, jackals, and animals are all individual subsets contained inside the larger group of wolves. Since no relationship or overlap is specified between these three inner subsets, they can be entirely separate from each other within the boundary of wolves. Therefore, neither "Some animals are tigers" nor "Some jackals are animals" necessarily holds true.

Explanation

Applying the specified operations to each digit of 5723946:

5 (odd) - 2 = 3 7 (odd) - 2 = 5 2 (even) + 3 = 5 3 (odd) - 2 = 1 9 (odd) - 2 = 7 4 (even) + 3 = 7 6 (even) + 3 = 9

The new number formed is 3551779. In this number, the digit 5 appears twice and the digit 7 appears twice. Therefore, 2 digits appear more than once.

Explanation

The relationship followed between the letter-clusters is a constant shift of -2 in the alphabetical position for each letter.

For the first pair (# : OIM): Q (17) - 2 = O (15) K (11) - 2 = I (9) O (15) - 2 = M (13) This gives # = QKO.

For the second pair (ICG : %): I (9) - 2 = G (7) C (3) - 2 = A (1) G (7) - 2 = E (5) This gives % = GAE.

Explanation

In the standard English alphabetical order, all other pairs follow a pattern where each letter in the second cluster is advanced by 1 position (+1) from the corresponding letter in the first cluster. In KM-NP, the letters advance by 3 positions (+3) from the first cluster (K + 3 = N and M + 3 = P), making it the odd pair that does not belong to the group.

Explanation

The pattern in each letter-cluster pair involves moving each letter forward by 6 positions (+6) in the alphabetical sequence.

For the left pair, using TDL: T (+6) = Z D (+6) = J L (+6) = R

For the right pair, using VFN: P (+6) = V Z (+6) = F H (+6) = N

Both pairs consistently follow the +6 positional shift rule for all three letters.

Explanation

Comparing 'ALIT' (coded as '2159') and 'HILT' (coded as '6912'), the three common letters are I, L, and T, which correspond to the three common digits 1, 2, and 9.

The letter remaining in 'HILT' after removing I, L, and T is H, and the digit remaining in '6912' after removing 1, 2, and 9 is 6. Thus, H is coded as 6.

Explanation

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

Placing P at position 1, counting two people to the right of P (counter-clockwise) puts B at position 5.

Since Q sits to the immediate left of B (position 6), O and S must be placed on the other side of P. S sits between O and P, placing S at position 2 and O at position 3.

C is not an immediate neighbor of P, so C sits at position 4, which leaves R at position 7.

The clockwise sequence starting from P is P, S, O, C, B, Q, R. Counting three positions to the left of R in the clockwise direction leads to P (1st), S (2nd), and O (3rd).

Explanation

The differences between consecutive terms in the series follow a pattern of multiples of 7:

10 - 3 = 7 24 - 10 = 14 45 - 24 = 21 73 - 45 = 28

Following this sequence, the next difference is 28 + 7 = 35.

Adding 35 to the last term gives 73 + 35 = 108.

Explanation

In the standard pattern, each pair follows a positional increment of +4 between the first two letters, +1 to transition from the second to the third letter, and +4 between the last two letters. In EI-IP, the letter positions are E (5), I (9), I (9), and P (16), which give letter differences of +4, +0, and +7 respectively, failing to follow the consistent (+4, +1, +4) rule.

Explanation

The pattern follows a positional shift in the English alphabet of +4, +5, -4, and -5 for consecutive letters:

First letter: +4 Second letter: +5 Third letter: -4 Fourth letter: -5

Applying this pattern to TCWK: T (20) + 4 = 24 → X C (3) + 5 = 8 → H W (23) - 4 = 19 → S K (11) - 5 = 6 → F

Combining the resulting letters yields XHSF.

Explanation

Assigning days 1 to 7 from Monday to Sunday: V is on day 3 (Wednesday). Since only one person has an engagement after Y, Y is on day 6 (Saturday). Since three people are between V and X, X is on day 7 (Sunday). Z and T are on consecutive days, placing Z on day 4 (Thursday) and T on day 5 (Friday). W is on day 2 (Tuesday), leaving one person (V) between W and Z. U takes day 1 (Monday).

With U on day 1 (Monday) and T on day 5 (Friday), there are 3 people (W, V, and Z) with engagements between them.

Explanation

Tracking the movement relative to Point A (0, 0) on a Cartesian plane: First, 18 km West moves to (-18, 0). Turning left (South) for 15 km moves to (-18, -15). Turning right (West) for 12 km moves to (-30, -15). Turning right (North) for 15 km moves to (-30, 0). Turning right (East) for 5 km moves to (-25, 0), which is Point P.

Since Point P is located 25 km west of Point A, to return from Point P to Point A, Logan needs to drive 25 km towards east.
