Question 1021

RRB Group D 2025• General Intelligence & Reasoning

XBNO is related to UYKL in a certain way based on the English alphabetical order. In the same way, PAQJ is related to MXNG. To which of the given options is FWOM related, following the same logic?

  1. AOption (a)

    GXPN

  2. BOption (b)

    CTLJ

  3. COption (c)

    BSKI

  4. DOption (d)

    DUMK

View answer & explanation

Correct answer

Answer: (b)B.

CTLJ

Why this answer is correct

Logic followed here is:

Logic: Each letter in the first word is shifted backward by 3 positions in the English alphabetical series to obtain the corresponding letter of the second word.

XBNO is related to UYKL →

PAQJ is related to MXNG →

The pattern observed is: (Positional value of letter - 3) = Resulting letter.

Similarly, let's find the related word for FWOM:

Therefore, the word related to 'FWOM' is CTLJ.

Hence, the correct answer is "Option 2".

Question 1022

RRB Group D 2025• General Intelligence & Reasoning

What should come in place of the question mark (?) in the given series?

40 47 55 64 74 ?

  1. AOption (a)

    81

  2. BOption (b)

  4. DOption (d)

    87

View answer & explanation

Correct answer

Answer: (c)C.

85

Why this answer is correct

Logic followed here is:

The series follows a pattern where the difference between consecutive terms increases by 1 at each step.

Next term in series = 74 + 11 = 85

 

Therefore, the number that should come in place of the question mark is 85.

Hence, the correct answer is "Option 3".

Why this answer is correct

Given Series:

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

We need to find the even numbers which are:

→ Immediately preceded by an odd number

→ Immediately followed by an even number

Required pattern: Odd → Even → Even

Checking the series:

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

The even numbers satisfying the condition are:

2 in (1 2 4)

4 in (1 4 2)

Therefore, the number of such even numbers is 2.

Hence, the correct answer is "Option 2".

P×
Q÷
R−
S+

Given Equation:

(20 Q 4) P 7 S 5 P 9 R (40 Q 8) P 4 = ?

Replace the letters with symbols:

⇒ (20 ÷ 4) × 7 + 5 × 9 − (40 ÷ 8) × 4

⇒ (5 × 7) + (5 × 9) − (5 × 4)

⇒ 35 + 45 − 20

⇒ 80 − 20

⇒ 60

Therefore, the value that comes in place of the question mark is 60.

Hence, the correct answer is "Option 3".

View answer & explanation

Correct answer

Answer: (a)A.

OOTF

Why this answer is correct

Logic followed here is:

The relationship between the letter clusters is established by applying a specific arithmetic sequence (-5, +4, -3, +2) to the positional values of the letters in the English alphabet.

For

DQXG is related to YUUI →

 

GLQC is related to BPNE →

The pattern observed is: -5, +4, -3, +2 applied to the positional values.

Similarly, let's find the code for TKWD:

 

Therefore, 'TKWD' is related to 'OOTF'.

Hence, the correct answer is "Option 1".

Question 1032

RRB Group D 2025• 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.)

  3. COption (c)

    CGH

  4. DOption (d)

Correct answer

Answer: (c)C.

CGH

Why this answer is correct

Checking Option 1: JMO

Checking Option 2: RUW

 

Checking Option 3: CGH

Checking Option 4: YBD

 

 

 

The pattern for JMO, RUW, and YBD is (+3, +2). However, for CGH, the pattern is (+4, +1).

Therefore, the letter-cluster 'CGH' does not belong to the group.

Hence, the correct answer is "Option 3".

Why this answer is correct

Logic followed here is:

Arrange the digits of the given number in ascending order and then identify the digits at the specified positions to calculate their sum.

The given number is 1785643

1785643

 

Arranging the digits in ascending order (from left to right):

1345678

In the new arrangement (1345678):

  1. The digit which is third from the left is: 4

  2. The digit which is third from the right is: 6

 

Sum of the digits:

Sum = 4 + 6 = 10

 

Therefore, the sum of the digits which are third from the left and third from the right is 10.

Hence, the correct answer is "Option 4".

    (9, 3, 629)

View answer & explanation

Correct answer

Answer: (c)C.

(5, 6, 900)

Why this answer is correct

Logic followed here is:  (1st Number × 2nd Number)2 = 3rd Number.

For (4, 7, 784) →

Calculation: (4 × 7)2 = (28)2 = 784

For (6, 3, 324) →

Calculation: (6 × 3)2 = (18)2 = 324

Similarly, let's check the options:

Option (3): (5, 6, 900) →

Calculation: (5 × 6)2 = (30)2 = 900

Therefore, the set that follows the same logic is (5, 6, 900).

Hence, the correct answer is "Option 3".

Venn Diagram Logic:

Conclusions:

(I) Some mufflers are caps: Does not follows (Because “Some scarfs are mufflers” does not guarantee that mufflers are caps.)

(II) Some scarfs are hats: Follows (Because all caps are both scarfs and hats. Therefore, at least some scarfs are hats.)

Therefore, only conclusion (II) follows.

Hence, the correct answer is "Option 3".

  3. COption (c)

    RNH

  4. DOption (d)

View answer & explanation

Correct answer

Answer: (a)A.

IFY

Why this answer is correct

Logic followed here is: (Letter 1 - 4 = Letter 2) and (Letter 2 - 6 = Letter 3).

  1. For IFY:

2) For ZVP →

3) For RNH →

 

4) For GCW →

 

Therefore, the letter-cluster 'IFY' does not belong to the group as it follows a -3, -7 pattern instead of -4, -6.

Hence, the correct answer is "Option 1".
