Question 481

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

FR 6 is related to KN -6 in a certain way. In the same way, LU 9 is related to QQ -3. To which of the following is LS 14 related, following the same logic?

  1. AOption (a)

    PR 0

  2. BOption (b)

    YT 8

  3. COption (c)

    QO 2

  4. DOption (d)

    GT 6

View answer & explanation

Correct answer

Answer: (c)C.

QO 2

Why this answer is correct

The logic follows here, 

For FR 6 is related to KN -6 

For LU 9 is related to QQ -3, 

LS 14 related ,

The term QO 2 is obtained by applying the same (+5, −4, −12) pattern to LS 14.

Hence, the correct answer is 'Option 3'.

Question 482

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 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)

    MJ – IF

  2. BOption (b)

    XA – TU

  3. COption (c)

    RF – NB

  4. DOption (d)

    PL – LH

View answer & explanation

Correct answer

Answer: (b)B.

XA – TU

Why this answer is correct

The logic followed here is, 

Logic: 1st letter of first cluster − 4 = 1st letter of second cluster; 2nd letter of first cluster − 4 = 2nd letter of second cluster.

For MJ - IF,

For RF - NB,

For  PL - LH,

For  XA - TU,

 

Therefore, the letter-cluster pair that is different from the others is XA - TU.

Hence, the correct answer is "Option 2".

Question 483

GAO 81 , EYM 75 , CWK 69 , AUI 63 , ?

  1. AOption (a)

    YSG 57

  2. BOption (b)

    YRJ 50

  3. COption (c)

    XSF 52

  4. DOption (d)

    XRF 55

View answer & explanation

Correct answer

Answer: (a)A.

YSG 57

Why this answer is correct

The logic followed here is:

The next term is "YSG 57".

Hence, the correct answer is "option 1"

Question 484

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

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

8 6 9 23 87 ?

  1. AOption (a)

    437

  2. BOption (b)

    433

  3. COption (c)

    421

  4. DOption (d)

    429

View answer & explanation

Correct answer

Answer: (d)D.

429

Why this answer is correct

The logic followed here is:

  • 8 × 1 − 2 = 6

  • 6 × 2 − 3 = 9

  • 9 × 3 − 4 = 23

  • 23 × 4 − 5 = 87

  • 87 × 5 − 6 = 429

Thus, the missing term in the series is 429.

Hence, the correct answer is 'Option 4';

Question 485

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

Mr. Vasu starts from Point A and drives 23 km towards the south. He then takes a left turn, drives 19 km, turns left and drives 36 km. He then takes a left turn and drives 19 km, turns left drives 9 km. He then takes a right turn and drives 5 km. He takes a final left turn, drives 4 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)

    5 km to the east

  2. BOption (b)

    8 km to the north

  3. COption (c)

    4 km to the west

  4. DOption (d)

    7 km to the south

View answer & explanation

Correct answer

Answer: (a)A.

5 km to the east

Why this answer is correct

Given :

  • Mr. Vasu starts from Point A and drives 23 km towards the south.
  • He then takes a left turn, drives 19 km, turns left and drives 36 km.
  • He then takes a left turn and drives 19 km, turns left drives 9 km.
  • He then takes a right turn and drives 5 km.
  • He takes a final left turn, drives 4 km and stops at Point P.

The Final Diagram , 

Hence, the correct answer is "option 1"

Question 486

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

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

7 11 20 24 46 50 ?

  1. AOption (a)

    100

  2. BOption (b)

    98

  3. COption (c)

    102

  4. DOption (d)

    96

View answer & explanation

Correct answer

Answer: (b)B.

98

Why this answer is correct

The logic followed here is:

  • 7 + 4 = 11
  • 11 × 2 − 2 = 20
  • 20 + 4 = 24
  • 24 × 2 − 2 = 46
  • 46 + 4 = 50
  • 50 × 2 − 2 = 98

Thus, the missing term in the series is 98.

Hence, the correct answer is 'Option 2';

Question 487

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 is the one 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)

    OR-KM

  2. BOption (b)

    SV-OQ

  3. COption (c)

    QT-MO

  4. DOption (d)
