Question 111

RRB Technician 2026• General Intelligence & Reasoning

Six friends B, C, L, M, N and O are sitting around a circular table facing the center of the table. L sits fourth to the right of O. Only one person sits between M and N when counted from the left of M. L sits third to the left of C. B is an immediate neighbor of C and N. How many people sit between L and B when counted from the left of B?

  1. AOption (a)

    Three

  2. BOption (b)

    One

  3. COption (c)

    Four

  4. DOption (d)

    Two

View answer & explanation

Correct answer

Answer: (a)A.

Three

Why this answer is correct

  1. Since all persons face the centre: right = counter-clockwise (CCW), left = clockwise (CW). Fix O at pos(1). L sits fourth to the right of O (CCW): O(1) → 2 → 3 → 4 → L(5).

  2. L sits third to the left of C. This means C sits third to the right of L (CCW): L(5) → 6 → 1 → C(2). So, C is at pos(2).

  3. B is an immediate neighbor of C and N. Since O is at pos(1), B must be at pos(3) to be next to C, and N must be at pos(4) so that B is also next to N.

  4. The last person M fills the remaining pos(6). This fits the condition: one person (L) sits between M and N from the left of M (CW): M(6) → L(5) → N(4).

To find the number of people between L and B when counted from the left of B (clockwise direction): Starting from B(3) going CW: C(2), O(1), M(6), and then we reach L(5). The people sitting between them are C, O, and M, which is a total of three people.

 

Hence, the correct answer is 'Option 1'.

Question 112

RRB Technician 2026• General Intelligence & Reasoning

Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster DOES NOT belong to that group?

​

(Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)

  1. AOption (a)

    TYE

  2. BOption (b)

    MRX

  3. COption (c)

    PUA

  4. DOption (d)

    GKP

View answer & explanation

Correct answer

Answer: (d)D.

GKP

Why this answer is correct

The logic followed here is the gap between the letters based on their positional values in the English alphabetical series.

Logic: 1st Letter + 5 = 2nd Letter and 2nd Letter + 6 = 3rd Letter.

Option 1) TYE,

Option 2) MRX,

Option 3) PUA

Option 4) GKP

This letter-cluster follows a +4, +5 pattern and does not belong to the group.

Therefore, the letter-cluster that is different from the others is GKP.

Hence, the correct answer is 'Option 4'.

  1. AOption (a)

    None

  2. BOption (b)

    Two

  3. COption (c)

    Three

  4. DOption (d)

    One

View answer & explanation

Correct answer

Answer: (d)D.

One

Why this answer is correct

The logic followed here is to compare the position of each letter in the word COMBINED with its position when the letters are arranged in English alphabetical order.

Original Word:

COMBINED
1st2nd3rd4th5th6th7th8th

 

Arranging letters in English Alphabetical Order:

BCDEIMNO
1st2nd3rd4th5th6th7th8th

 

Comparison of positions:

  • Position 1: C → B (Changed)
  • Position 2: O → C (Changed)
  • Position 3: M → D (Changed)
  • Position 4: B → E (Changed)
  • Position 5: I → I (Unchanged)
  • Position 6: N → M (Changed)
  • Position 7: E → N (Changed)
  • Position 8: D → O (Changed)

Only the letter I remains in the same position as in the original word.

Therefore, the position of One letter remains unchanged.

Hence, the correct answer is "Option 4".

View answer & explanation

Correct answer

Answer: (a)A.

uk

Why this answer is correct

Logic followed here is.

The code for a specific word is determined by comparing the given sentences to identify the unique common word and its corresponding common code.

Analysis of the given sentences:

  1. 'door closed now' is coded as 'vt xg uk'

  2. 'school is closed' is coded as 'cw uk ne'

Therefore, 'closed' is coded as 'uk'.

Hence, the correct answer is "Option 1".

  4. DOption (d)

    92

View answer & explanation

Correct answer

Answer: (b)B.

94

Why this answer is correct

Logic followed here is:

Logic: The difference between consecutive terms in the series increases by 1 at each step, representing a sequence of consecutive natural numbers starting from 8.

 

Therefore, the missing number that should come in place of the question mark is 94.

Hence, the correct answer is "Option 2".

    Three

  2. BOption (b)

    One

  3. COption (c)

    Two

  4. DOption (d)

    Four

View answer & explanation

Correct answer

Answer: (a)A.

Three

Why this answer is correct

The arrangement of seven people A, B, C, P, S, T, and U sitting in a straight line facing North is determined as follows:

1) Only three people are seated to the left of S.

2) Only A is seated to the right of B.

3) Only three people are seated between B and C.

4) P is seated at some place to the left of T, but at some place to the right of U.

 

Final Arrangement:

Calculation of people between U and T:

U is at the 1st position and T is at the 5th position.

The people seated between them are C (2nd), P (3rd), and S (4th).

Total number of people = 3.

Therefore, there are three people seated between U and T.

Hence, the correct answer is "Option 1".

Question 118

RRB Technician 2026• General Intelligence & Reasoning

Select the pair which follows the same pattern as that followed by the two pairs given below. Both pairs follow the same pattern.

KSD : HPA

FXM : CUJ

  1. AOption (a)

    HRC : EOY

  2. BOption (b)

    NBJ : JZH

  3. COption (c)

    LIQ : IFN

  4. DOption (d)

    ATU : XRS

View answer & explanation

Correct answer

Answer: (c)C.

LIQ : IFN

Why this answer is correct

The logic followed in this pattern is based on a consistent shift in the alphabetical positions of the letters.

For 'KSD' related to 'HPA':

K(11)S(19)D(4)
−3 ↓−3 ↓−3 ↓
H(8)P(16)A(1)

For 'FXM' related to 'CUJ':

F(6)X(24)M(13)
−3 ↓−3 ↓−3 ↓
C(3)U(21)J(10)

Applying the same logic to 'LIQ':

L(12)I(9)Q(17)
−3 ↓−3 ↓−3 ↓
I(9)F(6)N(14)

Thus, LIQ is related to IFN by the same pattern.

Hence, the correct answer is 'Option 3'.

Question 119

RRB Technician 2026• General Intelligence & Reasoning

Based on the English alphabetical order, three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which letter-cluster pair DOES NOT belong to that group?

(Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)

  1. AOption (a)

    QK - VH

  2. BOption (b)

    AE - FB

  3. COption (c)

    WH - BD

  4. DOption (d)

    GQ - LN

View answer & explanation

Correct answer

Answer: (c)C.

WH - BD

Why this answer is correct

The logic followed here is

Logic: First letter of the second cluster = First letter of the first cluster + 5; Second letter of the second cluster = Second letter of the first cluster − 3.

Option 1)  QK - VH,

Option 2) AE - FB,

Option 3) WH - BD

This pair does not follow the rule.

Option 4) GQ - LN,

Therefore, the letter-cluster pair that is different from the others is WH - BD.

Hence, the correct answer is 'Option 3'.
