Question 724

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 bottles are jars. All jars are boxes.

Conclusions

(I) Some boxes are bottles.

(II) All boxes are jars.

  1. AOption (a)

    Only conclusion (II) follows

  2. BOption (b)

    Neither conclusion (I) nor (II) follows

  3. COption (c)

    Only conclusion (I) follows

  4. DOption (d)

    Both conclusions (I) and (II) follow

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 boxes are bottles - Follow

(Some bottles are boxes, and some boxes are bottle. Hence, it is true)

(II) All boxes are jars -  Doesn't follow

All jars are boxes but all boxes are jars is may be possible but not definite. Hence, it is false)

Only conclusion (I) follows.

Hence, the correct answer is "Option 3"

Question 725

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

WTQT is related to VSPS in a certain way based on the English alphabetical order. In the same way, ZWTW is related to YVSV. To which of the following is OLIL related, following the same logic?

  1. AOption (a)

    NLGO

  2. BOption (b)

    NJGK

  3. COption (c)

    NKGK

  4. DOption (d)

    NKHK

View answer & explanation

Correct answer

Answer: (d)D.

NKHK

Why this answer is correct

The logic follows here, 

For 'WTQT' related to 'VSPS':

For 'ZWTW' related to 'YVSV':

Applying the same logic to 'OLIL':

Thus, OLIL is related to NKHK following the same logic.

Hence, the correct answer is 'Option 4'.

Question 726

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

In a certain code language, ‘GLOW’ is coded as ‘3187’ and ‘WOLF’ is coded as ‘1273’. What is the code for ‘G’ in the given code language?

  1. AOption (a)

    8

  2. BOption (b)

    3

  3. COption (c)

    1

  4. DOption (d)

    7

View answer & explanation

Correct answer

Answer: (a)A.

8

Why this answer is correct

The logic follows here,

Therefore, the code for G must be 8.

Hence, the correct answer is "option 1"

Question 727

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

In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. 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.)

78 - 88

32 - 42

  1. AOption (a)

    90 - 110

  2. BOption (b)

    98 - 88

  3. COption (c)

    45 - 56

  4. DOption (d)

    110 - 120

View answer & explanation

Correct answer

Answer: (d)D.

110 - 120

Why this answer is correct

The logic followed here is:

Logic: Second Number = First Number + 10

For the first pair 78 − 88

⇒ 78 + 10 = 88

For the second pair 32 − 42

⇒ 32 + 10 = 42

Applying the same Logic to the correct pair:

110 − 120

⇒ 110 + 10 = 120

Hence, the correct answer is "Option 4".

Question 728

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

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

280 225 175 130 90 55 ?

  1. AOption (a)

    31

  2. BOption (b)

    25

  3. COption (c)

    34

  4. DOption (d)

    28

View answer & explanation

Correct answer

Answer: (b)B.

25

Why this answer is correct

The logic follows here, 

  • 280 − 55 = 225
  • 225 − 50 = 175
  • 175 − 45 = 130
  • 130 − 40 = 90
  • 90 − 35 = 55
  • 55 − 30 = 25

Thus, the missing term in the series is 25.

Hence, the correct answer is 'Option 2';

Question 729

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)

    KJ-PZ

  2. BOption (b)

    PO – UE

  3. COption (c)

    FE-KU

  4. DOption (d)

    HG – NW

View answer & explanation

Correct answer

Answer: (d)D.

HG – NW

Why this answer is correct

The logic follows here, 

KJ-PZ,

PO - UE,

FE-KU,

HG - NW,

  Therefore, the letter-cluster pair that is different from the others is HG - NW.

Hence, the correct answer is 'Option 4'.

Question 730

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

In a certain code language,

A + B means ‘A is the sister of B’,

A - B means ‘A is the daughter of B’,

A × B means ‘A is the son of B’, and

A ÷ B means ‘A is the husband of B’.

Based on the above, how is V related to R if ‘V - D + Q × T ÷ R’?

  1. AOption (a)

    Son’s wife

  2. BOption (b)

    Sister’s daughter

  3. COption (c)

    Daughter’s daughter

  4. DOption (d)

    Daughter

View answer & explanation

Correct answer

Answer: (c)C.

Daughter’s daughter

Why this answer is correct

The family tree diagram is , 

Symbol+-×÷
MeaningSisterDaughterSonHusband

Given : V - D + Q × T ÷ R

From the family tree, it is clear that T and R are the parents of Q and D. Since D is the mother of V, it follows that V is the daughter of R's daughter → V is the Daughter's daughter of R.

Hence, the correct answer is 'Option 3'.
