Question 421

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

In a certain code language,

A ≠ B means ‘A is the sister of B’

A * B means ‘A is the father of B’

A ; B means ‘A is the son of B’

A + B means ‘A is the wife of B’

Based on the above, how is F related to O if 'F ≠ G ; H + M * O'?

  1. AOption (a)

    Husband's father's sister

  2. BOption (b)

    Brother's wife

  3. COption (c)

    Sister

  4. DOption (d)

    Wife

Correct answer

Answer: (c)C.

Sister

Why this answer is correct

Preparing the family tree diagram by using the following symbols:

As per the given information:

Let us first decode the given symbols and then draw a family tree.

Symbol≠*;+
MeaningSisterFatherSonWife

Given:  'F ≠ G ; H + M * O'

Based on the family tree, H and M are a married couple with three children: F, G, and O. Since F is female and they all share the same parents, F is the sister of O.

Hence, the correct answer is "Option 3"

Question 422

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

LEMO is related to RJST in a certain way based on the English alphabetical order. In the same way, JYKI is related to PDQN.

To which of the following options is BNCX related, following the same logic?

  1. AOption (a)

    HSIC

  2. BOption (b)

    CISH

  3. COption (c)

    SHIK

  4. DOption (d)

    KISH

View answer & explanation

Correct answer

Answer: (a)A.

HSIC

Why this answer is correct

The logic followed in this pattern is a series of alphabetical shifts where each letter is moved forward by a specific number of positions.

For 'LEMO' related to 'RJST':

L(12)E(5)M(13)O(15)
+6 ↓+5 ↓+6 ↓+5 ↓
R(18)J(10)S(19)T(20)

For 'JYKI' related to 'PDQN':

J(10)Y(25)K(11)I(9)
+6 ↓+5 ↓+6 ↓+5 ↓
P(16)D(4)Q(17)N(14)

Applying the same logic to 'BNCX':

B(2)N(14)C(3)X(24)
+6 ↓+5 ↓+6 ↓+5 ↓
H(8)S(19)I(9)C(3)

Thus, BNCX is related to HSIC following the pattern +6, +5, +6, +5.

Hence, the correct answer is 'Option 1'.

Question 423

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)

    XBA

  2. BOption (b)

    ZDC

  3. COption (c)

    DHG

  4. DOption (d)

    HMK

View answer & explanation

Correct answer

Answer: (d)D.

HMK

Why this answer is correct

The logic follows here, 

Logic: 1st letter + 4 = 2nd letter; 2nd letter − 1 = 3rd letter.

For XBA,

For  ZDC,

For  DHG,

For  HMK,

This letter cluster does not follow the rule.

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

Hence, the correct answer is 'Option 4'.

Question 424

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

Based on the English 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)

    ZDB

  2. BOption (b)

    VZX

  3. COption (c)

    YCA

  4. DOption (d)

    BGD

View answer & explanation

Correct answer

Answer: (d)D.

BGD

Why this answer is correct

The logic follows here, 

Logic: Second letter = First letter + 4; Third letter = Second letter − 2.

For ZDB,

For  VZX,

For YCA,

For  BGD,

  

 

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

Hence, the correct answer is 'Option 4'.

Required Condition: Consonant - Consonant − Vowel 

(Left) Y O W G U R C X Z H M E S I K A Q D F T B (Right)

W G U  , H M E 

Hence, the correct answer is "Option 3"

Question 426

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

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 degrees turns only unless specified.)

  1. AOption (a)

    20 km to the North

  2. BOption (b)

    21 km to the South

  3. COption (c)

    19 km to the West

  4. DOption (d)

    18 km to the East

View answer & explanation

Correct answer

Answer: (d)D.

18 km to the East

Why this answer is correct

Given:  

  • Mr. Yorly starts from Point A and drives 4 km towards South. He then takes a left turn, drives 23 km, turns left and drives 8 km.
  • He then takes a left turn and drives 41 km.
  • He takes a final left turn, drives 4 km and stops at Point P

The Final Diagram,

18 km to the East.

Hence, the  correct answer is " Option 4"

Question 427

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

  1. AOption (a)

    bx

  2. BOption (b)

    rn

  3. COption (c)

    vd

  4. DOption (d)

    lu

View answer & explanation

Correct answer

Answer: (b)B.

rn

Why this answer is correct

The logic followed here is

Compare the first and second sentences.

​

Thus, the code for food is rn.

Hence, the correct answer is "Option 2"

Question 428

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.

Statements: All apples are fruits. Some fruits are sweet.

Conclusions

(I) Some apples are sweet.

(II) All fruits are apples.

  1. AOption (a)

    Both conclusions (I) and (II) follow

  2. BOption (b)

    Only conclusion (II) follows

  3. COption (c)

    Neither conclusion (I) nor (II) follows

  4. DOption (d)

    Only conclusion (I) follows

View answer & explanation

Correct answer

Answer: (c)C.

Neither conclusion (I) nor (II) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

Conclusion

(I) Some apples are sweet -  Doesn't follow

(There is no direct relation between apples and sweets; maybe it is possible but not definite. Hence, it is false.)

(II) All fruits are apples - Doesn't follow

(All apples are fruit and all fruits are apples may be possible but not definite. Hence, it is false)

Neither conclusion (I) nor (II) follows

Hence, the correct answer is "Option 3"

Question 429

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

What will come in place of the question mark (?) in the following equation if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?

1 ÷ 1 × 1 + 2 − 49 = ?

  1. AOption (a)

    50

  2. BOption (b)

    46

  3. COption (c)

    49

  4. DOption (d)

    48

View answer & explanation

Correct answer

Answer: (d)D.

48

Why this answer is correct

BODMAS Table:

Given equation: 1 ÷ 1 × 1 + 2 − 49 = ?

Sign Interchange Mapping:

Original Sign÷×+−
Interchanged Sign×÷−+

 

Applying the interchanges to the expression and applying BODMAS rule:

= 1 × 1 ÷ 1 − 2 + 49

= 1 × 1 − 2 + 49

= 1 + 49 − 2

= 50 − 2

= 48

Hence, the correct answer is "option 4"

Question 430

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

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

232 ? 204 288 176 316

  1. AOption (a)

    260

  2. BOption (b)

    270

  3. COption (c)

    240

  4. DOption (d)

    250

View answer & explanation

Correct answer

Answer: (a)A.

260

Why this answer is correct

The logic follows here, 

  • 232 + 28 = 260
  • 260 − 56 = 204
  • 204 + 84 = 288
  • 288 − 112 = 176
  • 176 + 140 = 316

By following this pattern, the missing number in the series is 260.

Hence, the correct answer is "option 1"
