View answer & explanation

Correct answer

Answer: (c)C.

18

Why this answer is correct

Given: 2 is added to each odd digit and 2 is subtracted from each even digit in the number 6127385.

Given5973642
Operation-2-2-2-2+2+2+2
New number3751864

The new number formed is 3751864.

Sum of all the even digits in the new number thus formed: 8 + 6 + 4 = 14

Hence, the correct answer is "Option 3".

Question 22

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

    QNT

  2. BOption (b)

    MJP

  3. COption (c)

    URY

  4. DOption (d)

    JGM

View answer & explanation

Correct answer

Answer: (c)C.

URY

Why this answer is correct

The logic followed here ,

Logic: (First letter − 3) = Second letter; (Second letter + 6) = Third letter.

Option 1) QNT:

Option 2) MJP:

Option 4) JGM:

Option 3) URY:

 

This letter-cluster does not follow the same rule as the others.

Therefore, the letter-cluster that is different from the others is URY.

Hence, the correct answer is 'Option 3'.

Question 23

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

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 / subtracting / multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

8 - 3 - 24

5 - 8 - 40

  1. AOption (a)

    2 - 9 - 15

  2. BOption (b)

    14 - 6 - 34

  3. COption (c)

    4 - 8 - 43

  4. DOption (d)

    4 - 9 - 36

View answer & explanation

Correct answer

Answer: (d)D.

4 - 9 - 36

Why this answer is correct

The logic followed here is:

Logic: First Number × Second Number = Third Number

In (8 - 3 - 24)

⇒ 8 × 3 = 24

In (5 - 8 - 40)

⇒ 5 × 8 = 40

Similarly,

4 - 9 - 36

⇒ 4 × 9 = 36

Here, in (4, 9, 36) similar logic is followed.

Hence, the correct answer is 'Option 4'.

Question 24

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

Amit starts from Point Y and drives 14 km towards South. He then turns left and drives 35 km, takes a left and drives 68 km. He then takes a left turn and drives 41 km. He takes a left turn, drives 54 km, turns right and drives 53 km to stop at Point Z. How far (shortest distance) and towards which direction should he drive in order to reach Point Y again? (All turns are 90° turns only unless specified.)

  1. AOption (a)

    57 km towards east

  2. BOption (b)

    56 km towards west

  3. COption (c)

    61 km towards west

  4. DOption (d)

    59 km towards east

View answer & explanation

Correct answer

Answer: (d)D.

59 km towards east

Why this answer is correct

Given: 

  • Amit starts from Point Y and drives 14 km towards South.
  • He then turns left and drives 35 km, takes a left and drives 68 km.
  • He then takes a left turn and drives 41 km.
  • He takes a left turn, drives 54 km, turns right and drives 53 km to stop at Point Z
  • The final Diagram,

The shortest distance and the direction in which he should drive in order to reach Point Y again is = 53 km + 6 km = 59 km and in the east direction.

Hence, the correct answer is "Option 4".

Question 25

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

Each vowel in the word TRAJECTORIES is changed to the second letter immediately following it in the English alphabetical order, and each consonant is changed to the second letter immediately preceding it in the English alphabetical order. How many letters will appear exactly twice in the new group of letters thus formed?

  1. AOption (a)

    Three

  2. BOption (b)

    Four

  3. COption (c)

    Two

  4. DOption (d)

    One

View answer & explanation

Correct answer

Answer: (b)B.

Four

Why this answer is correct

The logic followed here is based on the positions of letters in the English alphabetical order.

Logic:

  • Vowels (A, E, I, O, U) are replaced by the letter that is 2 positions ahead (+2).
  • Consonants are replaced by the letter that is 2 positions behind (−2).

Applying the logic to the word TRAJECTORIES:

Original LetterTRAJECTORIES
Operation-2-2+2-2+2-2-2+2-2+2+2-2
New LetterRPCHGARQPKGQ

The new group of letters formed is: R, P, C, H, G, A, R, Q, P, K, G, Q

The letters that appear exactly twice are R, P, G, and Q are  4.

Hence, the correct answer is "Option 2".

Question 26

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

AEHB is related to FJMG in a certain way based on the English alphabetical order. In the same way, DHKE is related to IMPJ. To which of the following is GKNH related, following the same logic?

  1. AOption (a)

    PLMS

  2. BOption (b)

    PLSM

  3. COption (c)

    LPSM

  4. DOption (d)

    LPMS

View answer & explanation

Correct answer

Answer: (c)C.

LPSM

Why this answer is correct

The logic followed in this pattern is a consistent alphabetical shift of +5 for each letter in the sequence.

For 'AEHB' related to 'FJMG':

A(1)E(5)H(8)B(2)
+5 ↓+5 ↓+5 ↓+5 ↓
F(6)J(10)M(13)G(7)

For 'DHKE' related to 'IMPJ':

D(4)H(8)K(11)E(5)
+5 ↓+5 ↓+5 ↓+5 ↓
I(9)M(13)P(16)J(10)

Applying the same logic to 'GKNH':

G(7)K(11)N(14)H(8)
+5 ↓+5 ↓+5 ↓+5 ↓
L(12)P(16)S(19)M(13)

Thus, GKNH is related to LPSM.

Hence, the correct answer is 'Option 3'.

  4. DOption (d)

    11

View answer & explanation

Correct answer

Answer: (a)A.

15

Why this answer is correct

Given:  603 + 9 × 18 − 6 ÷ 56 = ?

After ‘+’ and ‘÷’ are interchanged and ‘−’ and ‘×’ are interchanged and using the BODMAS rule,

60b0eb2f30efad8be8bcdbeb 16418295992991

603 ÷ 9 − 18 × 6 + 56 = ?

= 603 ÷ 9 − 18 × 6 + 56

= 67 − 18 × 6 + 56

= 67 + 56 − 108 

= 123 − 108 

= 15

Hence, the correct answer is "Option 1".

S is father of P and T is sister of S. T is the Father's sister of P.

Hence, the correct answer is 'Option 4'.

Question 30

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

Uvx ranked 14th from the top and 79th from the bottom in his class. How many students are there in his class?

  1. AOption (a)

    93

  2. BOption (b)

    92

  3. COption (c)

    91

  4. DOption (d)

    90

View answer & explanation

Correct answer

Answer: (b)B.

92

Why this answer is correct

The logic followed here is:

Total number of students = (Rank from the top + Rank from the bottom) − 1

Given:

Rank of Uvx from the top = 14th

Rank of Uvx from the bottom = 79th

Total number of students = (Rank from the top + Rank from the bottom) − 1

= (14 + 79) − 1

= 93 − 1

= 92

Hence, the total number of students in the class is 92.

Hence, the correct answer is 'Option 2'.
