Question 521

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

Read the given statement(s) and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statement(s).

Statements: Some wings are toys. No toys are pens.

Conclusion (I): No pens are wings.

Conclusion (II): Some wings are not pens.

  1. AOption (a)

    Neither conclusion (I) nor (II) follows

  2. BOption (b)

    Only conclusion (II) follows

  3. COption (c)

    Both conclusions (I) and (II) follow

  4. DOption (d)

    Only conclusion (I) follows

View answer & explanation

Correct answer

Answer: (b)B.

Only conclusion (II) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

(I) No pens are wings - Doesn't follow

There is no direct relation between pens and wings may be it is possible but not definite. Hence, it is false)

(II) Some wings are not pens - Follow

(Some wings are toys that past of toys are not in pens. Non pens is toys. Hence, it is true)

Only conclusion (II) follows.

Hence, the correct answer is " Option 2"

Question 525

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

In a certain code language,

A @ B means ‘A is the mother 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 father of B’.

How is S related to H if ‘S × D ÷ R + Y @ H’?

  1. AOption (a)

    Mother

  2. BOption (b)

    Sister

  3. COption (c)

    Mother's mother

  4. DOption (d)

    Mother's sister

View answer & explanation

Correct answer

Answer: (c)C.

Mother's mother

Why this answer is correct

Preparing the family tree diagram by using the following symbols:

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

Symbol@×+÷
MeaningMotherWifeBrotherFather

Given:  S × D ÷ R + Y @ H

​Therefore, S is the mother of Y, who is the mother of H .S is the Mother's mother of H.

Hence, the correct answer is 'Option 3'.

Question 526

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

In a row of 46 people facing the north, Batul sits 33rd from the right end. If Jaya sits 31st from the left end of the row, how many people sit between Batul and Jaya?

  1. AOption (a)

    13

  2. BOption (b)

    18

  3. COption (c)

    16

  4. DOption (d)

    14

View answer & explanation

Correct answer

Answer: (c)C.

16

Why this answer is correct

The logic followed here is:

  • Total number of people in the row = 46
  • Position of Batul from the right end = 33rd
  • Position of Jaya from the left end = 31st

Position of Batul from the left = Total number of people − Position of Batul from the right + 1

= 46 − 33 + 1

= 14

Number of people between them = (Position of Jaya from the left − Position of Batul from the left) − 1

= 31 − 14 − 1

= 16

Hence, the correct answer is 'Option 3'.

Question 527

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

KEGJ is related to RLNQ in a certain way based on the English alphabetical order. In the same way, NHJM is related to UOQT.

To which of the following is QKMP related, following the same logic?

  1. AOption (a)

    RXWT

  2. BOption (b)

    XRWT

  3. COption (c)

    RXTW

  4. DOption (d)

    XRTW

View answer & explanation

Correct answer

Answer: (d)D.

XRTW

Why this answer is correct

The logic followed in this pattern is a series of alphabetical shifts based on the positional values of the letters.

For 'KEGJ' related to 'RLNQ':

For 'NHJM' related to 'UOQT',

Applying the same logic to 'QKMP':

Thus, QKMP is related to XRTW.

Hence, the correct answer is 'Option 4'.

Question 528

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

Each vowel in the word LIMEADE is changed to the letter immediately following it in the English alphabetical order, and each consonant is changed to the letter immediately preceding it in the English alphabetical order. How many letters will appear exactly twice in the new group of letters thus formed?

  1. AOption (a)

    One

  2. BOption (b)

    Two

  3. COption (c)

    Zero

  4. DOption (d)

    106

  4. DOption (d)

    108

View answer & explanation

Correct answer

Answer: (d)D.

108

Why this answer is correct

Logic followed here is,

BODMAS Table:

LetterABCD
Mathematical Sign÷×+−

 

Substituting the signs for the letters, and applying BODMAS rule the equation becomes:

= 2 × 32 ÷ 1 − 1 + 45

 

= 2 × 32 − 1 + 45

= 64 + 45 − 1

= 109 − 1

= 108

The final value obtained is 108.

Hence, the correct answer is "option 4."
