Ayush ranked 44th from the top and 25th from the bottom in his class. How many students are there in his class?

  1. AOption (a)

    66

  2. BOption (b)

View answer & explanation

Correct answer

Answer: (b)B.

68

Why this answer is correct

The logic followed here is:

Rank of Ayush from the top = 44th

Rank of Ayush from the bottom = 25th

Total number of students = (Rank from the top + Rank from the bottom) − 1

= (44 + 25) − 1

= 69 − 1

= 68

Hence, the correct answer is 'Option 2'.

Question 116

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

If 1 is added to each odd digit and 2 is subtracted from each even digit in the number 51748623, then how many digits will appear more than once in the new number thus formed?

  1. AOption (a)

    Two

Correct answer

Answer: (d)D.

Three

Why this answer is correct

Given number: 51748623

1 is added to each odd digit and 2 is subtracted from each even digit in the number 51748623

Digits will appear more than once in the new number, thus three are formed: 2, 6, and 4.

Hence, the correct answer is 'Option 4'.

Question 118

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

Tuv ranked 27th from the top and 64th from the bottom in his class. How many students are there in his class?

  1. AOption (a)

    90

  2. BOption (b)

View answer & explanation

Correct answer

Answer: (a)A.

90

Why this answer is correct

The logic followed here is:

Position of Tuv from the top = 27th

Position of Tuv from the bottom = 64th

Total number of students in the class = (Position from the top + Position from the bottom) − 1

= (27 + 64) − 1

= 91 − 1

= 90

Hence, the correct answer is 'Option 1'.

Question 119

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.)

  1. AOption (a)

    HL - NR

  2. BOption (b)

    DH - JN

  3. COption (c)

    KO - QV

  4. DOption (d)

View answer & explanation

Correct answer

Answer: (c)C.

KO - QV

Why this answer is correct

The logic followed here is

HL − NR,

DH − JN,

KO − QV

AE − GK,

Therefore, the letter-cluster pair that is different from the others is KO − QV.

Hence, the correct answer is 'Option 3'.
