    151

View answer & explanation

Correct answer

Answer: (c)C.

141

Why this answer is correct

The logic follows here, 

  • 111 + 3 = 114
  • 114 + 6 = 120
  • 120 + 9 = 129
  • 129 + 12 = 141
  • 141 + 15 = 156

Hence, the correct answer is "option 3"

Question 803

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

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

15 22 40 67 105 152 ?

  1. AOption (a)

    165

  2. BOption (b)

    210

  3. COption (c)

    167

  4. DOption (d)

    156

View answer & explanation

Correct answer

Answer: (b)B.

210

Why this answer is correct

The logic followed here is:

  • 15 + 7 = 22
  • 22 + 18 = 40
  • 40 + 27 = 67
  • 67 + 38 = 105
  • 105 + 47 = 152
  • 152 + 56 = 208

Thus, the missing term in the series is 210.

Hence, the correct answer is 'Option 2';

Question 804

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

Based on the English alphabetical order, three of the following four letter-cluster pairs 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 pairs.)

  1. AOption (a)

    HL-NR

  2. BOption (b)

    DH-JN

  3. COption (c)

    JO-QU

  4. DOption (d)

    FJ-LP

View answer & explanation

Correct answer

Answer: (c)C.

JO-QU

Why this answer is correct

The logic follows here, 

HL-NR,

DH-JN,

JO-QU,

FJ-LP,

Therefore, the letter-cluster pair that is different from the others is JO-QU.

Hence, the correct answer is 'Option 3'.

Question 808

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

All 145 people are standing in a row facing north. Ccd is 24th from the right end while Vks is 26th from the left end. How many people are there between Ccd and Vks?

  1. AOption (a)

    92

  2. BOption (b)

    94

    95

  4. DOption (d)

    98

View answer & explanation

Correct answer

Answer: (c)C.

95

Why this answer is correct

The logic followed here is:

  • Total number of people in the row = 145
  • Position of Vks from the left end = 26th
  • Position of Ccd from the right end = 24th

Number of people between Ccd and Vks = Total number of people − (Position of Vks from the left + Position of Ccd from the right)

= 145 − (26 + 24)

= 145 − 50

= 95

Hence, the correct answer is "Option 3"
