Question 231

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

In a certain code language, "EUOA" is coded as "53" and "YFMP" is coded as "71". What is the code for "RIZB" in that given language?

  1. AOption (a)

    56

  2. BOption (b)

    58

  3. COption (c)

    60

  4. DOption (d)

    66

View answer & explanation

Correct answer

Answer: (d)D.

66

Why this answer is correct

The logic follows here, 

Logic: The code for a word is determined by summing the positional values of its letters and then adding a constant number 11 to the sum.

For EUOA 

  • Sum of positional values = 5 + 21 + 15 + 1 = 42
  • Code = 42 + 11 = 53

 

YFMP 

  • Sum of positional values = 25 + 6 + 13 + 16 = 60
  • Code = 60 + 11 = 71

 

RIZB

  • Sum of positional values = 18 + 9 + 26 + 2 = 55

  • Code = 55 + 11 = 66

The correct answer is "option 4"

Given equation: 322 × 23 − 14 ÷ 463 + 232 = ?

After replacing the signs,using BODMAS rule

= 322 ÷ 23 × 14 + 463 − 232

=  14 × 14 + 463 − 232

= 196 + 463 − 232

= 659 − 232

= 427

Hence, the correct answer is "Option 4."

Question 235

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)

    BCY

  2. BOption (b)

    FGC

  3. COption (c)

    LNI

  4. DOption (d)

    NOK

View answer & explanation

Correct answer

Answer: (c)C.

LNI

Why this answer is correct

The logic follows here, 

Logic: The second letter is obtained by adding 1 to the first letter, and the third letter is obtained by subtracting 4 from the second letter.

For BCY

 

For FGC

 

For NOK

 

For LNI,

The odd one is LNI

Hence, the correct answer is "option 3"

Required Conditions: Consonant , Vowels, Consonant

Left  U L Y M R D E L C D A E H R O H F X L D W H Right 

There are a total of two such vowels in the given series. Hence, the correct answer is "Option 4."

Question 237

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

Correct answer

Answer: (c)C.

Four

Why this answer is correct

The logic follows here, 

Given:  Each vowel in the word WORTHLESSLY is changed to the second letter following it in the English alphabetical order AND each consonant is changed to the letter immediately preceding it in the English alphabetical order

WORTHLESSLY

The letters formed in the group are: V, Q, Q, S, G, K, G, R, R, K, X

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

Total number of letters appearing exactly twice = 4.

Hence, the correct answer is "option 3"

Question 238

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

View answer & explanation

Correct answer

Answer: (a)A.

(113, 178, 65)

Why this answer is correct

The logic followed here is:

Logic: Second Number − First Number = Third Number

For (163, 186, 23)

⇒ 186 − 163 = 23

For (144, 200, 56)

⇒ 200 − 144 = 56

Applying the same logic to the options:

For (113, 178, 65)

⇒ 178 − 113 = 65

Hence, the correct answer is "Option 1".

Correct answer

Answer: (a)A.

None

Why this answer is correct

Given:  Seven people H, I, J, K, W, Y and Z are sitting in a row facing north

  • Only J sits to the left of W.
  • Only four people sit between J and Y.
  • Only I sits between K and H and K is not an immediate neighbor of Y

The Final Arrangement is, 

No one sits to the right of Z.

Hence, the correct answer is "option 1"

Question 240

  3. COption (c)

    91

  4. DOption (d)

    111

View answer & explanation

Correct answer

Answer: (a)A.

99

Why this answer is correct

The logic follows here, 

  • 90 + 13 = 91
  • 91 + 23 = 99
  • 99 + 33 = 126
  • 126 + 43 = 190
  • 190 + 53 = 315

The term that should come in place of the question mark (?) in the series is 99.

Hence, the correct answer is "option 1"
