Question 501

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

Based on the English alphabetical order, three of the following four letter-cluster pairs 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 pairs.)

  1. AOption (a)

    MO – EU

  2. BOption (b)

    UW-MC

  3. COption (c)

    SU-KA

  4. DOption (d)

    ZB – PH

View answer & explanation

Correct answer

Answer: (d)D.

ZB – PH

Why this answer is correct

The logic followed here is ,

MO - EU,

UW - MC,

SU - KA,

ZB - PH,

Therefore, the letter-cluster pair that is different from the others is ZB - PH.

Hence, the correct answer is 'Option 4'.

Question 502

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.

Statements: Some poets are writers. All writers are dreamers.

Conclusions:

(I) Some dreamers are poets.

(II) All poets are dreamers.

  1. AOption (a)

    Only conclusion (II) follows

  2. BOption (b)

    Both conclusions (I) and (II) follow

  3. COption (c)

    Only conclusion (I) follows

  4. DOption (d)

    Neither conclusion (I) nor (II) follows

View answer & explanation

Correct answer

Answer: (c)C.

Only conclusion (I) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

(I) Some dreamers are poets.  - Follows 

(all writers are dreamers and some poets are writers, the poets who are writers must also be dreamers)

(II) All poets are dreamers. - Doesn't follows

(Some poets are dreamers, all writers are dreamers.  All poets are dreamers is may be possible but not definite. Hence, it is false)

Only conclusion (I) follows

Hence, the correct answer is " Option 3"

Question 503

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.)

  3. COption (c)

    (346, 173, 188)

  4. DOption (d)

    (114, 57, 72)

View answer & explanation

Correct answer

Answer: (a)A.

(62, 31, 45)

Why this answer is correct

The logic followed here is:

Logic: Second Number = First Number ÷ 2; Third Number = Second Number + 14

For the first set (14, 7, 21)

⇒ 14 ÷ 2 = 7

⇒ 7 + 14 = 21.

For the second set (56, 28, 42)

⇒ 56 ÷ 2 = 28

⇒ 28 + 14 = 42.

Applying the same logic to the options

Checking Option 1: (62, 31, 45)

⇒ 62 ÷ 2 = 31

⇒ 31 + 14 = 45.

Hence, the correct answer is 'Option 1'.

Question 505

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

In a row of 15 students facing the north, Yusuf is 10th from the right end. If Suman is 4th to the left of Yusuf, what is Suman's position from the left end of the line?

  1. AOption (a)

    3rd

  2. BOption (b)

    4th

  3. COption (c)

    1st

  4. DOption (d)

    2nd

View answer & explanation

Correct answer

Answer: (d)D.

2nd

Why this answer is correct

The logic followed here is:

Total number of students in the row = 15

Position of Yusuf from the right end = 10th

Position of Yusuf from the left end = (Total number of students − Position from the right end) + 1

= 15 − 10 + 1

= 6th

Since the students are facing North, Suman is 4th to the left of Yusuf, which means Suman is closer to the left end of the row.

Position of Suman from the left end = Position of Yusuf from the left end − 4

= 6 − 4

= 2nd

Hence, the correct answer is 'Option 4'.

  3. COption (c)

    53rd

  4. DOption (d)

    52nd

View answer & explanation

Correct answer

Answer: (d)D.

52nd

Why this answer is correct

The logic followed here is:

Total number of students in the row = 122

Position of Ccd from the right end = 54th

Vks is 17th to the left of Ccd.

Position of Vks from the right end = Position of Ccd from the right end + 17

= 54 + 17 = 71th

Position of Vks from the left end = (Total number of students − Position of Vks from the right end) + 1

= (122 − 71) + 1

= 51 + 1

= 52nd

Hence, the correct answer is 'Option 4'.
