Question 121

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

Jay ranked 12th from the bottom and 9th from the top in his class. How many students are there in his class?

  1. AOption (a)

    20

  2. BOption (b)

    18

  3. COption (c)

    19

  4. DOption (d)

    17

View answer & explanation

Correct answer

Answer: (a)A.

20

Why this answer is correct

The logic followed here is:

Position of Jay from the top = 9th

Position of Jay from the bottom = 12th

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

= (9 + 12) − 1

= 21 − 1

= 20

Hence, the correct answer is 'Option 1'.

Question 122

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

In a certain code language,

A % B means ‘A is the father of B’,

A € B means ‘A is the wife of B’,

A = B means ‘A is the brother of B’, and

A ? B means ‘A is the daughter of B’.

Based on the above, how is B related to X if 'B = C ? O % P € X'?

  1. AOption (a)

    Wife's brother

  2. BOption (b)

    Brother

  3. COption (c)

    Father

  4. DOption (d)

    Wife's father

View answer & explanation

Correct answer

Answer: (a)A.

Wife's brother

Why this answer is correct

Family Chart

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

Symbol%€=?
MeaningFatherWifeBrotherDaughter

 

Given: B = C ? O % P € X

The Family tree diagram is,

​Therefore, B is the brother of P, who is the wife of X → B is the Wife's brother of X.

Hence, the correct answer is 'Option 1'.

Question 123

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

HLJN is related to JNLP in a certain way based on the English alphabetical order. In the same way, EIGK is related to GKIM. To which of the following is FJHL related, following the same logic?

  1. AOption (a)

    HKIN

  2. BOption (b)

    HLIN

  3. COption (c)

    HLJN

  4. DOption (d)

    HMIN

View answer & explanation

Correct answer

Answer: (c)C.

HLJN

Why this answer is correct

The logic followed in this pattern is based on the English alphabetical order, where each letter in the group is shifted forward by 2 positions.

For 'HLJN' related to 'JNLP':

H(8)L(12)J(10)N(14)
+2 ↓+2 ↓+2 ↓+2 ↓
J(10)N(14)L(12)P(16)

For 'EIGK' related to 'GKIM':

E(5)I(9)G(7)K(11)
+2 ↓+2 ↓+2 ↓+2 ↓
G(7)K(11)I(9)M(13)

Applying the same logic to 'FJHL':

F(6)J(10)H(8)L(12)
+2 ↓+2 ↓+2 ↓+2 ↓
H(8)L(12)J(10)N(14)

Thus, FJHL is related to HLJN.

Hence, the correct answer is 'Option 3'.

Question 124

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)

    JKL

  2. BOption (b)

    FGH

  3. COption (c)

    BDD

  4. DOption (d)

    LMN

View answer & explanation

Correct answer

Answer: (c)C.

BDD

Why this answer is correct

The logic followed here is:

 

For, JKL

For, FGH

For, BDD

For , LMN

The letter clusters JKL, FGH, and LMN follow a common pattern, whereas BDD is the odd one out.

Hence, the correct answer is "Option 3"

Question 125

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

  1. AOption (a)

    LHM

  2. BOption (b)

    RNS

  3. COption (c)

    OKM

  4. DOption (d)

    UQV

View answer & explanation

Correct answer

Answer: (c)C.

OKM

Why this answer is correct

The pattern followed here is,

Logic: First letter − 4 = Second letter and Second letter + 5 = Third letter.

LHM,

RNS,

 

OKM,

 

UQV,

Therefore, the letter-cluster that is different from the others is OKM.

Hence, the correct answer is 'Option 3'.

  1. AOption (a)

    4

  2. BOption (b)

    6

  3. COption (c)

    2

  4. DOption (d)

Q and G

Why this answer is correct

Given: Seven people, F, G, H, L, M, O, and Q, are sitting around a circular table, facing the center of the table.

  1. Only one person sits between Q and L when counted from the right of Q.

  2. Only one person sits between L and M when counted from the left of M.

  3. Only one person sits between Q and G when counted from the right of G.

  4. Only two people sit between H and M when counted from the left of M.

  5. Only one person sits between F and G when counted from the right of F.
