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)

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'.

View answer & explanation

Correct answer

Answer: (b)B.

6

Why this answer is correct

Logic followed here is the comparison of words to identify common letters and their corresponding numerical codes.

Given:

PINS is coded as 3247

HIPS is coded as 4627

Step 1: Identify common letters in both words.

The letters common to PINS and HIPS are P, I, and S.

Step 2: Identify common digits in both numerical codes.

The digits common to 3247 and 4627 are 2, 4, and 7.

This implies that the set of letters {P, I, S} corresponds to the set of digits {2, 4, 7}.

Step 3: Determine the code for H.

In the word HIPS, the letter that remains after removing P, I, and S is H.

In the code 4627, the digit that remains after removing 2, 4, and 7 is 6.

Therefore, the code for H is 6.

The correct answer is option 2

Why this answer is correct

The logic followed in the given number series is as follows:

Logic: (Previous number × Multiplier) − 2 = Next number

 

  • 28 × 0.5 − 2 = 14 − 2 = 12
  • 12 × 1.0 − 2 = 12 − 2 = 10
  • 10 × 1.5 − 2 = 15 − 2 = 13
  • 13 × 2.0 − 2 = 26 − 2 = 24
  • 24 × 2.5 − 2 = 60 − 2 = 58

 

The next term in the series is 58.
