Question 791

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: All ants are wings. No logs are wings.

Conclusion (I): No logs are ants.

Conclusion (II): Some wings are ants.

  1. AOption (a)

    Only conclusion (I) follows 

  2. BOption (b)

    Only conclusion (II) follows

  3. COption (c)

    Both conclusions (I) and (II) follow

  4. DOption (d)

    Neither conclusion (I) nor (II) follows

View answer & explanation

Correct answer

Answer: (c)C.

Both conclusions (I) and (II) follow

Why this answer is correct

The least possible Venn diagram for the given statements is:

(I) No logs are ants - Follow (As their is no direct relaton establish between logs and ants may be it is possible but not definte)

(II) Some wings are ants - Follows (All ants are wings and some wings anre ants and some wings are ants)

Both conclusions (I) and (II) follow.

Hence, the correct answer is " Option 3"

Correct answer

Answer: (b)B.

Two

Why this answer is correct

Given: Seven people, H, I, J, K, W, Y, and Z, are sitting in a row facing north.

  1. No one sits to the left of H.
  2. Only four people sit between H and I.
  3. Only three people sit to the right of W.
  4. Z sits to the immediate left of J.
  5. Y is not an immediate neighbor of W

The Final Arrangement is, 

So, there are Two people sitting between Y and W.

Hence, the correct answer is "option 2"

Question 793

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

Pqr ranked 71st from the bottom and 39th from the top in his class. How many students are there in his class?

  1. AOption (a)

    108

  2. BOption (b)

    107

  3. COption (c)

    109

  4. DOption (d)

    113

View answer & explanation

Correct answer

Answer: (c)C.

109

Why this answer is correct

The logic followed here is:

Rank of Pqr from the top = 39th

Rank of Pqr from the bottom = 71st

Total number of students in the class = Rank from the top + Rank from the bottom − 1

= 39 + 71 − 1

= 110 − 1

= 109

Hence, the correct answer is 'Option 3'.

Question 794

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

Select the set in which the numbers are related in the same way as are the numbers of the following sets.

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

    19, 211

  2. BOption (b)

    22, 246

  3. COption (c)

    24, 264

  4. DOption (d)

    16, 176

View answer & explanation

Correct answer

Answer: (a)A.

19, 211

Why this answer is correct

The logic followed here is:

Logic: Second Number = (First Number × 11) + 2

For the first set 18, 200

⇒ (18 × 11) + 2

⇒ 198 + 2 = 200.

For the second set 17, 189

⇒ (17 × 11) + 2

⇒ 187 + 2 = 189.

Applying the same logic to the options:

For Option 1: 19, 211

⇒ (19 × 11) + 2

⇒ 209 + 2 = 211.

Hence, the correct answer is 'Option 1'.

Question 795

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

Based on the 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)

    KJM

  2. BOption (b)

    FEH

  3. COption (c)

    TTV

  4. DOption (d)

View answer & explanation

Correct answer

Answer: (c)C.

TTV

Why this answer is correct

The logic follows here, 

KJM,

FEH,

TTV,

ZYB,

Therefore, the letter cluster that is different from the others is TTV.

Hence, the correct answer is 'Option 3'.

Question 796

View answer & explanation

Correct answer

Answer: (c)C.

BZV

Why this answer is correct

The logic follows here, 

EBY,

TQN,

BZV

FCZ,

Therefore, the letter cluster that is different from the others is BZV.

Hence, the correct answer is 'Option 3'.

Question 797

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

In a certain code language,

A ÷ B means ‘A is the son 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)

    Father

  2. BOption (b)

    Husband

  3. COption (c)

    Brother

  4. DOption (d)

Correct answer

Answer: (c)C.

Brother

Why this answer is correct

The family tree diagram is ,

Symbol÷#+&
MeaningSonWifeBrotherFather

Given : S ÷ D # R & Y + H

Therefore, S, Y, and H are the children of D and R. Since S is a son, S is the Brother of H.

Hence, the correct answer is 'Option 3'.

Question 798

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

Select the triad that follows the same pattern as that followed by the two sets of triads given below. Both triads follow the same pattern.

BATH –HBAT –THBA

TOYS –STOY -YSTO

  1. AOption (a)

    CART - ACTR - CTAR 

  2. BOption (b)

    TOMB -OMTB -MTOB

  3. COption (c)

    LOVE- OVEL -VELO

  4. DOption (d)

    ABLE-EABL-LEAB

View answer & explanation

Correct answer

Answer: (d)D.

ABLE-EABL-LEAB

Why this answer is correct

The logic followed in this pattern is a cyclic shift of letters, where the last letter of the word is moved to the first position to form the next word in the sequence.

For the triad 'BATH – HBAT – THBA':

BATH
↓ Last letter moves to first ↓
HBAT
↓ Last letter moves to first ↓
THBA

For the triad 'TOYS – STOY – YSTO':

TOYS
↓ Last letter moves to first ↓
STOY
↓ Last letter moves to first ↓
YSTO

Applying the same logic to the correct triad:

ABLE
↓ Last letter moves to first ↓
EABL
↓ Last letter moves to first ↓
LEAB

The sequence ABLE – EABL – LEAB follows the exact pattern of shifting the last character to the front.

Hence, the correct answer is 'Option 4'.

Question 799

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 fishes are watches.

No watch is an octopus.

Conclusions:

(I) Some fishes are octopus.

(II) Some watches are fishes.

  1. AOption (a)

    Neither conclusion (I) nor (II) follows

  2. BOption (b)

    Only conclusion (II) follows

  3. COption (c)

    Only conclusion (I) follows

  4. DOption (d)

    Both conclusions (I) and (II) follow

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) Some fishes are octopus - Don't follows

(There is no intersection between the fishes circle and the octopus circle. Since no definite relation is given, it does not follow.)

(II) Some watches are fishes - Follows

(Since some fishes are watches, there is a definite intersection between the two sets, which implies some watches are also fishes.)

Only conclusion (II) follows

Hence, the correct answer is "Option 2"

Correct answer

Answer: (a)A.

3

Why this answer is correct

BODMAS Table: 

According to the question, the signs are interchanged as follows:

  • ‘+’ and ‘−’ are interchanged.
  • ‘×’ and ‘÷’ are interchanged.

Given equation: 558 × 31 − 18 ÷ 17 + 321 = ?

After interchanging the signs, using the BODMAS rule the new equation is:

= 558 ÷ 31 + 18 × 17 − 321

= 18 + 18 × 17 − 321 

= 18 + 306 − 321 

= 324 − 321

= 3

Hence, the correct answer is "option 1"
