Question 561

RRB Group D 2026• General Intelligence & Reasoning

NETI is related to XODS in a certain way based on the English alphabetical order. In the same way, BSHW is related to LCRG. To which of the following options is FWLA related, following the same logic?

  1. AOption (a)

    PGBN

  2. BOption (b)

    PGVK

  3. COption (c)

    PKLO

  4. DOption (d)

    PVHY

View answer & explanation

Correct answer

Answer: (b)B.

PGVK

Why this answer is correct

The logic followed here is:

For, NETI → XODS

For, BSHW → LCRG

Now, applying the same logic for FWLA

So, FWLA → PGVK

Hence, the correct answer is "Option 2".

Correct answer

Answer: (d)D.

3

Why this answer is correct

Given: (Left) 4 3 5 1 2 9 8 9 4 7 7 4 5 4 8 5 6 2 4 7 3 3 4 6 3 7 5 (Right)

Now,

Odd numbers which are immediately preceded by an odd number and immediately followed by an even number.

So, needed pattern is: Odd - Odd - Even

(Left) 4 3 5 1 2 9 8 9 4 7 7 4 5 4 8 5 6 2 4 7 3 3 4 6 3 7 5 (Right)

So, total valid odd numbers = 3

Hence, the correct answer is Option 4.

Question 563

RRB Group D 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 is the letter-cluster pair that 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)

    DG−HK

  2. BOption (b)

    GJ−KN

  3. COption (c)

    TW−XA

  4. DOption (d)

    HK−KQ

View answer & explanation

Correct answer

Answer: (d)D.

HK−KQ

Why this answer is correct

The logic followed here is based on the alphabetical position pattern:

Option 1: DG → HK

Option 2: GJ → KN

Option 3: TW → XA

Option 4: HK → KQ

Thus, Options 1, 2, and 3 follow a consistent +4 shift pattern, while Option 4 deviates from this rule.

Hence, the odd one out is Option 4.

Question 564

RRB Group D 2026• General Intelligence & Reasoning

Seven boxes, D, E, F, U, V, W and X, are kept one over the other but not necessarily in the same order.

Only U is kept above D. Only V is kept between D and F. No box is kept below E. Only three boxes are kept between D and W. How many boxes are kept between X and E?

  1. AOption (a)

    One

  2. BOption (b)

    Two

  3. COption (c)

    Four

  4. DOption (d)

    Three

View answer & explanation

Correct answer

Answer: (a)A.

One

Why this answer is correct

Given: Seven boxes U, D, V, F, W, E and X are kept one over the other but not necessarily in the same order.

Only U is kept above D.

Only V is kept between D and F.

No box is kept below E.

Only three boxes are kept between D and W

PositionBox
1 (Top)U
2D
3V
4F
5X
6W
7 (Bottom)E

Now, Boxes between X (5) and E (7) → W (6) → 1 box

Hence, the correct answer is Option 1.

Question 566

RRB Group D 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 is the letter-cluster pair that 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)

    TO - NI

  2. BOption (b)

    UP - OI

  3. COption (c)

    VQ - PK

  4. DOption (d)

    QL - KF

View answer & explanation

Correct answer

Answer: (b)B.

UP - OI

Why this answer is correct

The logic followed here is based on the alphabetical position pattern:

Option 1: TO → NI

Option 2: UP → OI

Option 3: VQ → PK

Option 4: QL → KF

Thus, Options 1, 3, and 4 follow a consistent -6 shift pattern for both letters, while Option 2 deviates from this rule.

Hence, the odd one out is Option 2.

Question 567

RRB Group D 2026• General Intelligence & Reasoning

Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusion(s) logically follow(s) from the statements.

Statements:

Some rails are cars.

No car is a bus.

Conclusions:

(I) Some rails are bus.

(II) Some cars are rails.

  1. AOption (a)

    Only conclusion (I) follows.

  2. BOption (b)

    Only conclusion (II) follows.

  3. COption (c)

    Both conclusions (I) and (II) follow.

  4. DOption (d)

    Neither conclusion (I) nor (II) follows.

View answer & explanation

Correct answer

Answer: (b)B.

Only conclusion (II) follows.

Why this answer is correct

Given

Statements:

Some rails are cars.

No car is a bus.

The least possible Venn diagram for the given statement is:

Conclusions:

I. Some rails are bus - Does not follow (Because rails that are cars cannot be buses, and no definite relation is given between remaining rails and buses).

II. Some cars are rails - Follows (Since “Some rails are cars” can be directly converted to “Some cars are rails”).

So, only conclusion II follows.

Hence, the correct answer is Option 2.
