Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?

FEL 17, KIQ 21, PMV 25, UQA 29, ?

  1. AOption (a)

    YUF 32

  2. BOption (b)

    ZUF 33

  3. COption (c)

    ZVG 33

  4. DOption (d)

    YVG 32

View answer & explanation

Correct answer

Answer: (b)B.

ZUF 33

Why this answer is correct

The logic followed here is:

The pattern observed for the letters is (+5, +4, +5) and for the numbers, it is +4. Combining these parts, the next term in the series is ZUF 33.

Hence, the correct answer is "Option 2"

View answer & explanation

Correct answer

Answer: (a)A.

Father's brother

Why this answer is correct

Family Chart:

 

The family tree diagram is , 

Therefore, Lakhan is the father of Amrita, and Nehal  is the brother of Lakhan . This means Nehal is the Father's brother of Amrita.

Hence, the correct answer is 'Option 1'.

Question 574

RRB NTPC 2026• General Intelligence and Reasoning• General Intelligence and Reasoning

Mr. Vasu starts from Point A and drives 25 km towards the West. He then takes a left turn, drives 15 km, turns left and drives 51 km. He then takes a left turn, drives 28 km, turns left and drives 14 km. He then takes a left turn and drives 6 km. He takes a final right turn, drives 12 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)

    8 km to the North

  2. BOption (b)

    10 km to the East

  3. COption (c)

    9 km to the West

  4. DOption (d)

    7 km to the South

View answer & explanation

Correct answer

Answer: (d)D.

7 km to the South

Why this answer is correct

  • Mr. Vasu starts from Point A and drives 25 km towards the West.
  • He then takes a left turn, drives 15 km, turns left and drives 51 km.
  • He then takes a left turn, drives 28 km, turns left and drives 14 km.
  • He then takes a left turn and drives 6 km.
  • He takes a final right turn, drives 12 km and stops at Point P

The Final Diagram, 

Therefore, he should drive 7 km to the South to reach Point A again.

Hence, the correct answer is " Option 4"

Question 575

RRB NTPC 2026• General Intelligence and Reasoning• General Intelligence and Reasoning

Based on the alphabetical order, three of the following four are alike in a certain way and thus form a group. Which is the one that does not belong to that group?

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

  1. AOption (a)

    UXZ

  2. BOption (b)

    LOQ

  3. COption (c)

    ZDE

  4. DOption (d)

    DGI

View answer & explanation

Correct answer

Answer: (c)C.

ZDE

Why this answer is correct

The logic followed here is,

Logic: The difference between the numerical positions of consecutive letters in the group is +3 and +2.

UXZ,

LOQ,

DGI,

ZDE,

 

This letter cluster follows a different pattern (+4, +1) and does not follow the rule.

Therefore, the letter cluster that is different from the others is ZDE.

Hence, the correct answer is 'Option 3'.

Question 576

RRB NTPC 2026• General Intelligence and Reasoning• General Intelligence and Reasoning

Each of the digits in the number 8254316 is arranged in ascending order from left to right. The position(s) of how many digits will remain unchanged as compared to that in the original number?

  1. AOption (a)

    Three

  2. BOption (b)

    One

  3. COption (c)

    None

  4. DOption (d)

    Two

View answer & explanation

Correct answer

Answer: (d)D.

Two

Why this answer is correct

Given number: 8254316

Arranging them in ascending order, : 1, 2, 3, 4, 5, 6, 8.

 

Now, let us compare the original number with the newly arranged sequence:

Original Number8254316
Ascending Order1234568

The positions of the digits 2 and 4 remain the same after rearrangement.

Hence, the correct answer is 'Option 4'.

Question 577

RRB NTPC 2026• General Intelligence and Reasoning• General Intelligence and Reasoning

What should come in place of ‘?’ in the given series?

56 57 ? 70 86 111

  1. AOption (a)

    61

  2. BOption (b)

    63

  3. COption (c)

    64

  4. DOption (d)

    62

View answer & explanation

Correct answer

Answer: (a)A.

61

Why this answer is correct

The numbers are increased by consecutive perfect squares.

  • 56 + 1² = 57
  • 57 + 2² = 61
  • 61 + 3² = 70
  • 70 + 4² = 86
  • 86 + 5² = 111

Hence, the missing number is:

57 + 4 = 61

Hence, the correct answer is "option 1"

Question 578

RRB NTPC 2026• General Intelligence and Reasoning• General Intelligence and 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 conclusions logically follow(s) from the statements.

Statement: Some Power Saws are Chisels. Some Chisels are Wrenches.

Conclusion (I): Some Power Saws are Wrenches.

Conclusion (II): No Power Saws are Wrenches.

  1. AOption (a)

    Both conclusions (I) and (II) follow

  2. BOption (b)

    Only conclusion (I) follows

  3. COption (c)

    Only conclusion (II) follows

  4. DOption (d)

    Neither conclusion (I) nor (II) follows

View answer & explanation

Correct answer

Answer: (d)D.

Neither conclusion (I) nor (II) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

(I) Some Power Saws are Wrenches - Doesn't Follows.(Their is no direct relation between PowerSawas and wrencehes may be it is possible but not definite. Hence, it is false)

(II) No Power Saws are Wrenches - Doesn't Follows.

(Their is no direct relation between PowerSawas and wrencehes may be it is possible but not definite. Hence, it is false)

Neither conclusion (I) nor (II) follows.

Hence, the correct answer is " Option 4"

Question 579

RRB NTPC 2026• General Intelligence and Reasoning• General Intelligence and 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)

    DV - PH

  2. BOption (b)

    JB - DN

  3. COption (c)

    NF - HR

  4. DOption (d)

    TL - NX

View answer & explanation

Correct answer

Answer: (a)A.

DV - PH

Why this answer is correct

The logic followed here is

DV - PH,

JB - DN,

NF - HR,

TL - NX,

Therefore, the letter-cluster pair that is different from the others is DV - PH.

Hence, the correct answer is 'Option 1'.
