Question 401

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

Read the given statements 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 statements.

Statement: All Eagles are Seagulls. Some Seagulls are Peacocks.

Conclusion (I): Some Eagles are Peacocks.

Conclusion (II): No Peacocks are Eagles.

  1. AOption (a)

    Only conclusion (II) follows

  2. BOption (b)

    Only conclusion (I) follows

  3. COption (c)

    Neither conclusion (I) nor (II) follows

  4. DOption (d)

    Both conclusions (I) and (II) follow

View answer & explanation

Correct answer

Answer: (c)C.

Neither conclusion (I) nor (II) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

(I) Some Eagles are Peacocks - Doesn't Follow

There is no direct relation between eagles and peacock. So, may be it is possible but not definite. Hence, it is false)

(II) No Peacocks are Eagles -  Doesn't Follow

There is no direct relation between eagles and peacock. So, may be it is possible but not definite. Hence, it is false)

Neither conclusion (I) nor (II) follows

Hence, the correct answer is "Option 3"

Question 402

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

In a certain code language,

J + Q means ‘J is the mother of Q’,

J – Q means ‘J is the brother of Q’,

J x Q means ‘J is the husband of Q’ and

J ÷ Q means ‘J is the sister of Q’.

Based on the above, how is A related to F if ‘A ÷ B x C + D – E ÷ F’?

  1. AOption (a)

    Father's sister

  2. BOption (b)

    Sister

  3. COption (c)

    Mother

  4. DOption (d)

    Mother's sister

View answer & explanation

Correct answer

Answer: (a)A.

Father's sister

Why this answer is correct

Preparing the family tree diagram by using the following symbols:

As per the given information:

Symbol+−×÷
MeaningMotherBrotherHusbandSister

Given: A ÷ B × C + D − E ÷ F

The Family tree diagram,

​Therefore, A is the sister of B, who is the father of F → A is the Father's sister of F.

Hence, the correct answer is 'Option 1'.

Answer: (a)A.

se

Why this answer is correct

The logic follows here, 

Hence, the code for the " add " is se

Hence, the correct answer is "option 1"

Question 404

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

What should come in place of ‘?’ in the given series?

4 10 18 38 74 ?

  1. AOption (a)

    154

  2. BOption (b)

    152

  3. COption (c)

    148

  4. DOption (d)

    150

View answer & explanation

Correct answer

Answer: (d)D.

150

Why this answer is correct

The logic followed here is:

  • 4 × 2 + 2 = 10
  • 10 × 2 − 2 = 18
  • 18 × 2 + 2 = 38
  • 38 × 2 − 2 = 74
  • 74 × 2 + 2 = 150

Thus, the missing term in the series is 150.

Hence, the correct answer is 'Option 4';

Question 405

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

Each vowel in the word RADULAE 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)

    Three

  2. BOption (b)

    One

  3. COption (c)

    Zero

  4. DOption (d)

    Two

View answer & explanation

Correct answer

Answer: (b)B.

One

Why this answer is correct

The logic followed here is,

Logic: Each vowel in the word is changed to the letter immediately following it (+1), and each consonant is changed to the letter immediately preceding it (−1) 

Given word :  RADULAE

RADULAE
−1+1−1+1−1+1+1
QBCVKBF

The new group of letters formed is: Q, B, C, V, K, B, F.

  • B appears exactly twice in the new sequence.
  • Therefore, the total count of letters appearing exactly twice is one.

Hence, the correct answer is "option 2"

Correct answer

Answer: (a)A.

8

Why this answer is correct

BODMAS Table:

Given equation:3 A 42 B 14 C 29 D 22 = ?

ABCD
÷×+−

 

Replacing the alphabets with signs and applying BODMAS rule:

= 3 ÷ 42 × 14 + 29 − 22

= (1/14) × 14 + 29 − 22

 

= 1 + 29 − 22

= 30 − 22

= 8

Hence, the correct answer is "option 1"
