Question 131

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 clouds are water. Some water is vapor.

Conclusions:

(I) Some clouds are vapor.

(II) Some vapor is water.

  1. AOption (a)

    Only conclusion (II) follows

  2. BOption (b)

    Neither conclusion (I) nor (II) follows

  3. COption (c)

    Only conclusion (I) follows

  4. DOption (d)

    Both conclusions (I) and (II) follow

View answer & explanation

Correct answer

Answer: (a)A.

Only conclusion (II) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

Conclusions:

(I) Some clouds are vapor -  Does not follow

(There is no direct relation between clouds and vapor maybe it is possible but not definite.)

(II) Some vapor is water. - Follows (Some water is vapor, and some vapour is water is true)

Only conclusion (II) follows

Hence the correct answer is "Option 1"

Correct answer

Answer: (b)B.

6

Why this answer is correct

Logic followed here is the comparison of words to identify common letters and their corresponding numerical codes.

Given:

PINS is coded as 3247

HIPS is coded as 4627

Step 1: Identify common letters in both words.

The letters common to PINS and HIPS are P, I, and S.

Step 2: Identify common digits in both numerical codes.

The digits common to 3247 and 4627 are 2, 4, and 7.

This implies that the set of letters {P, I, S} corresponds to the set of digits {2, 4, 7}.

Step 3: Determine the code for H.

In the word HIPS, the letter that remains after removing P, I, and S is H.

In the code 4627, the digit that remains after removing 2, 4, and 7 is 6.

Therefore, the code for H is 6.

The correct answer is option 2

Question 133

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

In a certain code language,

'A @ B' means ‘A is the mother of B’,

'A & B' means ‘A is the husband of B’,

'A # B' means ‘A is the father of B’,

'A % B' means ‘A is the son of B’ and

'A * B' means ‘A is the daughter of B’.

If G @ K & V * P # W % J, then how is J related to K?

  1. AOption (a)

    Wife’s sister

  2. BOption (b)

    Wife's mother

  3. COption (c)

    Mother

  4. DOption (d)

    Daughter

View answer & explanation

Correct answer

Answer: (b)B.

Wife's mother

Why this answer is correct

Family Chart

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

Symbol@&#%*
MeaningMotherHusbandFatherSonDaughter

 

Given: G @ K & V * P # W % J

The family tree diagram is , 

Based on the tree, V is the daughter of J, and K is the husband of V. Therefore, J is the Wife's mother of K.

Hence, the correct answer is 'Option 2'.

Question 134

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

In a certain code language, ‘unit flash zebra’ is coded as ' mi de cz' and ‘zebra dance king’ is coded as ‘de uv id’. How is ‘zebra’ coded in the given language?

  1. AOption (a)

    cz

  2. BOption (b)

    uv

  3. COption (c)

    mi

  4. DOption (d)

    de

View answer & explanation

Correct answer

Answer: (d)D.

de

Why this answer is correct

The logic follows here, 

  • unit flash zebra → mi de cz
  • zebra dance king → de uv id

 

The code for zebra is de.

Hence, the correct answer is "Option 4"

Question 135

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

Refer to the following series and answer the question. (Counting to be done from left to right only.) (All numbers are single-digit numbers only.)

(Left) 9 7 6 4 3 5 7 6 4 6 7 6 9 8 7 7 6 6 7 6 5 7 6 8 7 5 6 (Right)

How many such even digits are there, each of which is immediately preceded by a perfect square and immediately followed by an even digit? (NOTE: 1 is also a perfect square)

    Two

  2. BOption (b)

    One

  3. COption (c)

    Three

  4. DOption (d)

Correct answer

Answer: (d)D.

None

Why this answer is correct

Given series:  9 7 6 4 3 5 7 6 4 6 7 6 9 8 7 7 6 6 7 6 5 7 6 8 7 5 6 

Required Condition: Perfect Square -  Even Digit - Even Digit

(Left) 9 7 6 4 3 5 7 6 4 6 7 6 9 8 7 7 6 6 7 6 5 7 6 8 7 5 6 (Right)​

Since no even digit in the series is simultaneously preceded by a perfect square and followed by an even digit, the total count is None.

Hence, the correct answer is 'Option 4'.​

Correct answer

Answer: (c)C.

Five

Why this answer is correct

Given: Seven people, L, V, H, D, E, F and T, are sitting in a row, facing north.

  • Only four people sit to the right of D.
  • V sits fourth from the left end.
  • E is the immediate neighbor of H and T.
  • F sits third to the left of T.

The Final Arrangement is,

The people sitting between L and H are F, D, V, T, and E.

Hence, the correct answer is "Option 3"

Question 137

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

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

28 12 10 13 24 ?

  1. AOption (a)

    58

  2. BOption (b)

    65

  3. COption (c)

    70

  4. DOption (d)

    60

View answer & explanation

Correct answer

Answer: (a)A.

58

Why this answer is correct

The logic followed in the given number series is as follows:

Logic: (Previous number × Multiplier) − 2 = Next number

 

  • 28 × 0.5 − 2 = 14 − 2 = 12
  • 12 × 1.0 − 2 = 12 − 2 = 10
  • 10 × 1.5 − 2 = 15 − 2 = 13
  • 13 × 2.0 − 2 = 26 − 2 = 24
  • 24 × 2.5 − 2 = 60 − 2 = 58

 

The next term in the series is 58.

Hence, the correct answer is "Option1"

Question 138

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)

    EGF

  2. BOption (b)

    BDC

  3. COption (c)

    HJI

  4. DOption (d)

    VYW

View answer & explanation

Correct answer

Answer: (d)D.

VYW

Why this answer is correct

The logic followed here is

Logic: First letter + 2 = Second letter; Second letter − 1 = Third letter

  EGF,

BDC,

 

HJI,

VYW,

This cluster does not follow the same logic as the others.

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

Hence, the correct answer is 'Option 4'.

Question 139

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

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

10 13 22 41 66 101 ?

  1. AOption (a)

    164

  2. BOption (b)

    142

  3. COption (c)

    146

  4. DOption (d)

    124

View answer & explanation

Correct answer

Answer: (b)B.

142

Why this answer is correct

The logic follows here. 

Logic: Double difference of 6 and 10.

  • 10 + 3 = 13
  • 13 + 9 = 22
  • 22 + 19 = 41
  • 41 + 25 = 66
  • 66 + 35 = 101
  • 101 + 41 = 142

Missing number  = 101 + 41 = 142

Hence, the correct answer is ''Option 2"
