Question 341

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

Each of the digits in the number 9342156 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)

    Two

  3. COption (c)

    None

  4. DOption (d)

    One

View answer & explanation

Correct answer

Answer: (c)C.

None

Why this answer is correct

Given original number: 9342156

When we arrange the digits of the number in ascending order from left to right, we obtain a new sequence of digits. Let's compare the original sequence with the new sequence position-wise:

Original number: 9 3 4 2 1 5 6

Ascending Order: 1 2 3 4 5 6 9

As observed, every digit has moved from its original position. There are no digits whose position remains unchanged after the rearrangement.

Hence, the correct answer is "Option 3"

Correct answer

Answer: (a)A.

T

Why this answer is correct

Given: Seven boxes X, Y, Z, W, V, U and T are kept one over the other but not necessarily in the same order.

  1. Y is placed at the bottommost position (Position 1).
  2. Box V is kept immediately above W.
  3. Box X is kept immediately below W.
  4. Exactly three boxes are kept between T and W.
  5. W is kept on one of the positions above T.

Question 343

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

What should come in place of the question mark (?) in the given series?

17 40 61 80 97 112 ?

  1. AOption (a)

    130

  2. BOption (b)

    122

  3. COption (c)

    127

  4. DOption (d)

    125

View answer & explanation

Correct answer

Answer: (d)D.

125

Why this answer is correct

The logic follows here, 

  • 17 + 23 = 40
  • 40 + 21 = 61
  • 61 + 19 = 80
  • 80 + 17 = 97
  • 97 + 15 = 112
  • 112 + 13 = 125

 

Thus, the missing term in the series is 125.

Hence, the correct answer is 'Option 4';

Question 344

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

  1. AOption (a)

    BEI

  2. BOption (b)

    VZC

  3. COption (c)

    HKO

  4. DOption (d)

    ZCG

View answer & explanation

Correct answer

Answer: (b)B.

VZC

Why this answer is correct

The logic follows here , 

Logic: The difference between the alphabetical positions of the consecutive letters in each cluster is +3 and +4.

For BEI,

For  VZC,

For HKO,

For ZCG,

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

Hence, the correct answer is 'Option 2'.

  1. AOption (a)

    24

  2. BOption (b)

    28

  3. COption (c)

    23

  4. DOption (d)

    35

View answer & explanation

Correct answer

Answer: (a)A.

24

Why this answer is correct

The logic follows here, 

The shaded part in the diagram shows engineers are there who are also athletes but not teachers

Total number of engineers are there who are also athletes but not teachers is 24.

Hence, the correct answer is "option 1"

Question 346

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.)

(99, 103, 111)

(157, 161, 169)

  1. AOption (a)

    (196, 198, 206)

  2. BOption (b)

    (112, 117, 125)

  3. COption (c)

    (208, 212, 220)

  4. DOption (d)

    (323, 328, 336)

View answer & explanation

Correct answer

Answer: (c)C.

(208, 212, 220)

Why this answer is correct

The logic followed here is:

Logic: 2nd Number = 1st Number + 4; 3rd Number = 2nd Number + 8

For the first set (99, 103, 111)

⇒ 99 + 4 = 103.

⇒ 103 + 8 = 111.

Applying the same logic to the second set (157, 161, 169)

⇒ 157 + 4 = 161.

⇒ 161 + 8 = 169.

Applying the same logic to the set in Option 3

(208, 212, 220)

⇒ 208 + 4 = 212.

⇒ 212 + 8 = 220.

Hence, the correct answer is 'Option 3'.

View answer & explanation

Correct answer

Answer: (d)D.

9

Why this answer is correct

Given number: 7213546

As per the given conditions, 2 is added to each odd digit and 2 is subtracted from each even digit:

The number formed after these operations is: 9035724

  • The highest digit is: 9
  • The lowest digit is: 0

So, the difference between the highest and lowest digits is: 9 - 0 = 9.

Hence, the correct answer is 'Option 4'.

Question 349

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

In a certain code language, "VINP" is coded as "61" and "FSKA" is coded as "85". What is the code for "TOYG" in the given language?

  1. AOption (a)

    69

  2. BOption (b)

    55

  3. COption (c)

    61

  4. DOption (d)

    63

View answer & explanation

Correct answer

Answer: (b)B.

55

Why this answer is correct

The logic follows here, 

**Logic:**The pattern observed is: (Sum of reverse positional values of letters) + 14.

For VINP is coded as 61,

  • Sum of reverse positional values = 5 + 18 + 13 + 11 = 47
  • Code = 47 + 14 = 61

 

For FSKA is coded as 85,

  • Sum of reverse positional values = 21 + 8 + 16 + 26 = 71
  • Code = 71 + 14 = 85

 

Applying the same logic for TOYG,

  • Sum of reverse positional values = 7 + 12 + 2 + 20 = 41
  • Code = 41 + 14 = 55

 

Hence, the correct answer is "option 2"
