Question 1081

RRB Group D 2025• 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)

    US – ZS

  2. BOption (b)

    AY-DY

  3. COption (c)

    QO – TO

  4. DOption (d)

    SQ-VQ

View answer & explanation

Correct answer

Answer: (a)A.

US – ZS

Why this answer is correct

Logic followed here is: (Positional value of the first letter of the 1st cluster) + 3 = (Positional value of the first letter of the 2nd cluster).

1) US - ZS →

  1. AY - DY →

 

  1. QO - TO →

  2. SQ - VQ 

 

Therefore, the letter-cluster pair 'US - ZS' does not belong to the group.

Hence, the correct answer is "Option 1".

Question 1082

RRB Group D 2025• General Intelligence & Reasoning

In a row of 54 people facing north, Mohit sits 22nd from the right end. If Charu sits 15th from the left end of the row, how many people sit between Mohit and Charu?

  1. AOption (a)

    16

  2. BOption (b)

    18

  3. COption (c)

    15

  4. DOption (d)

    17

View answer & explanation

Correct answer

Answer: (d)D.

17

Why this answer is correct

Given:

Total people in the row = 54

Mohit sits 22nd from the right end.

Charu sits 15th from the left end.

Step 1:

Find Mohit’s position from the left end.

Formula:

Position from left = Total people − Position from right + 1

= 54 − 22 + 1

= 33

So, Mohit is 33rd from the left end.

Step 2:

Charu is 15th from the left end.

People between Mohit and Charu:

= 33 − 15 − 1

= 17

Therefore, 17 people sit between Mohit and Charu.

Hence, the correct answer is "Option 4".

Question 1083

RRB Group D 2025• General Intelligence & Reasoning

This question is based on the five, three-digit numbers given below.

(Left) 453 125 410 183 473 (Right)

(Example: 697 – First digit = 6, second digit = 9 and third digit = 7)

(

NOTE:

All operations to be done from left to right.)

What will be the resultant if the third digit of the highest number is added to the third digit of the lowest number?

  1. AOption (a)

    5

  2. BOption (b)

    11

  3. COption (c)

    7

  4. DOption (d)

    8

View answer & explanation

Correct answer

Answer: (d)D.

8

Why this answer is correct

Logic followed here is: The resultant is determined by identifying the highest and lowest numbers in the given set and then summing their respective third digits.

For

The highest number 473 →

Third digit of the highest number = 3

The lowest number 125 →

Third digit of the lowest number = 5

The pattern observed is: (Third digit of the highest number) + (Third digit of the lowest number).

Similarly, let's find the resultant:

Sum of third digits = 3 + 5 = 8

Therefore, the resultant is 8.

Hence, the correct answer is "Option 4".

  4. DOption (d)

    JVI

View answer & explanation

Correct answer

Answer: (a)A.

JWI

Why this answer is correct

Logic followed here is:

The next term in the series is determined by adding 2 to the positional values of the first and second letters, and subtracting 1 from the positional value of the third letter of the previous term in the English alphabetical order.

For

Next term = JWI

Therefore, the term in place of the question mark (?) is JWI.

Hence, the correct answer is "Option 1".

Question 1087

RRB Group D 2025• General Intelligence & Reasoning

If 1 is added to each odd digit and 1 is subtracted from each even digit in the number 3215674, what will be the difference between the highest and lowest digits in the new number thus formed?

  1. AOption (a)

    4

  2. BOption (b)

View answer & explanation

Correct answer

Answer: (c)C.

7

Why this answer is correct

Given:

Number = 3215674

Rule:

Add 1 to each odd digit.

Subtract 1 from each even digit.

Step 1: Form the new number

Original DigitOperationNew Digit
33 + 14
22 − 11
11 + 12
55 + 16
66 − 15
77 + 18
44 − 13

 

New number formed = 4126583

Step 2: Find highest and lowest digits

Highest digit = 8

Lowest digit = 1

Difference = 8 − 1 = 7

Therefore, the required difference is 7.

Hence, the correct answer is "Option 3".

  4. DOption (d)

    Only conclusion (II) follows

View answer & explanation

Correct answer

Answer: (a)A.

Neither conclusion (I) nor (II) follows

Why this answer is correct

Statements:

All bananas are grapes.

No banana is a cucumber.

Venn Diagram Logic:

Conclusions:

(I) Some cucumbers are grapes: Does not follows (There is no definite relation given between cucumbers and grapes.)

(II) All grapes are cucumbers: Does not follows (Only bananas are grapes is given. It does not mean all grapes are cucumbers.)

Therefore, neither conclusion (I) nor (II) follows.

Hence, the correct answer is "Option 1".

Question 1089

RRB Group D 2025• 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)

    MQ - KO

  2. BOption (b)

    KO - IM

  3. COption (c)

    PS - NR

  4. DOption (d)

    GK - EI

View answer & explanation

Correct answer

Answer: (c)C.

PS - NR

Why this answer is correct

Logic followed here is: (First letter-cluster positional values) - 2 = (Second letter-cluster positional values).

For

  1. MQ - KO :

  2. KO - IM :

 

  1. PS - NR:

  

  1. GK - EI :

  

 

Therefore, the letter-cluster pair PS - NR does not belong to the group as it subtracts 1 from the second letter instead of 2.

Hence, the correct answer is "Option 3".

Question 1091

RRB Group D 2025• General Intelligence & Reasoning

Sunil starts from point A and drives 64 km towards West. He then takes a left turn, drives 60 km, turns left and drives 67 km. He then takes a left turn and drives 78 km. He takes a final left turn, drives 3 km and stops at point P. How far (shortest distance) and towards which direction should he drive in order to reach point A again? (All turns are 90-degree turns only, unless specified.)

  1. AOption (a)

    19 km to the north

  2. BOption (b)

    18 km to the South

  3. COption (c)

    17 km to the South

  4. DOption (d)

    20 km to the north

View answer & explanation

Correct answer

Answer: (b)B.

18 km to the South

Why this answer is correct

Given:

Sunil starts from Point A.

  1. Drives 64 km towards West

  2. Takes a left turn and drives 60 km

  3. Takes a left turn and drives 67 km

  4. Takes a left turn and drives 78 km

  5. Takes a final left turn and drives 3 km to reach Point P

Step-by-step movement:

Horizontal movement:

West = 64 + 3 = 67 km

East = 67 km

Horizontal displacement = 0

Vertical movement:

North = 78 km

South = 60 km

Net movement = 18 km North

So Point P is 18 km to the north of Point A.

To reach Point A again, Sunil must travel 18 km towards the South.

Hence, the correct answer is "Option 2".

Select the set in which the numbers are related in the same way as are the numbers of the following sets.

(

NOTE:

Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding to/subtracting from/multiplying with 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

    (146, 302, 224)

View answer & explanation

Correct answer

Answer: (d)D.

(146, 302, 224)

Why this answer is correct

Logic followed here is: The third number is the average of the first and second numbers.

(First number + Second number) ÷ 2 = Third number

For (106, 368, 237) →

Calculation:

(106 + 368) ÷ 2 = 474 ÷ 2 = 237

 

For (114, 336, 225) →

Calculation:

(114 + 336) ÷ 2 = 450 ÷ 2 = 225

 

The pattern observed is: (First number + Second number) ÷ 2 = Third number.

Similarly, let's check the options:

Option (4): (146, 302, 224)

Calculation:

(146 + 302) ÷ 2 = 448 ÷ 2 = 224

 

Therefore, the set that follows the same logic is (146, 302, 224).

Hence, the correct answer is "Option 4".

View answer & explanation

Correct answer

Answer: (d)D.

VQSW

Why this answer is correct

Logic followed here is.

Logic: Each letter in the first cluster is shifted forward by 7 positions in the English alphabetical order to obtain the corresponding letter in the related cluster.

For

KFHL is related to RMOS →

MHJN is related to TOQU →

The pattern observed is: (Positional value of each letter) + 7.

Similarly, let's find the relation for OJLP:

Therefore, the term related to 'OJLP' is VQSW.

Hence, the correct answer is "Option 4".
