WSPO is related to SPNN in a certain way based on the English alphabetical order. In the same way, TQNL is related to PNLK . To which of the following is MKHI related, following the same logic?

  1. AOption (a)

    IHFH

  2. BOption (b)

    IGDE

  3. COption (c)

    IGEF

  4. DOption (d)

    TYWD

View answer & explanation

Correct answer

Answer: (a)A.

IHFH

Why this answer is correct

The logic followed in this pattern is ,

For 'WSPO' related to 'SPNN':

For 'TQNL' related to 'PNLK':

Applying the same logic to 'MKHI':

Thus, MKHI is related to IHFH.

Hence, the correct answer is 'Option 1'.

Question 834

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 cherries are bats.

No bat is an orange.

Conclusions:

(I) No cherry is an orange.

(II) Some oranges are bats.

  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: (a)A.

Only conclusion (I) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

(I) No cherry is an orange - Follows

Since all cherries are entirely inside the bats set, and the bats set has no intersection with oranges, it is impossible for any cherry to be an orange.

(II) Some oranges are bats - Don't Follows

The statement clearly specifies that no bat is an orange, which means the sets are completely disjoint; therefore, no orange can be a bat.

Only conclusion (I) follows.

Hence, the correct answer is "Option 1"

Question 835

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)

    Wife's brother

  2. BOption (b)

    Brother

  3. COption (c)

    Father

  4. DOption (d)

    Wife's father

View answer & explanation

Correct answer

Answer: (a)A.

Wife's brother

Why this answer is correct

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

Symbol÷#+&
MeaningSonWifeBrotherFather

Given : S ÷ D & R + Y # H’

Therefore, S is the brother of Y, who is the wife of H.S is the Wife's brother of H.

Hence, the correct answer is 'Option 1'.

Question 837

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

If ‘A’ stands for ‘÷’, ‘B’ stands for ‘×’, ‘C’ stands for ‘+’ and ‘D’ stands for ‘−’, then what will come in place of the question mark (?) in the following equation?

43 D 28 C 35 A 7 B 11 = ?

  1. AOption (a)

    71

  2. BOption (b)

    73

  3. COption (c)

  4. DOption (d)

    74

View answer & explanation

Correct answer

Answer: (c)C.

70

Why this answer is correct

ABCD
÷×+−

 

Given equation:

43 D 28 C 35 A 7 B 11 = ?

After replacing the letters with their respective mathematical signs, applying the BODMAS rule, the equation becomes:

= 43 − 28 + 35 ÷ 7 × 11

= 43 − 28 + 5 × 11

= 43 + 55 − 28

= 98 − 28

= 70

Hence, the correct answer is "option 3"

Question 838

View answer & explanation

Correct answer

Answer: (b)B.

ZSH -46

Why this answer is correct

The logic follows here, 

Hence, the correct answer is "option 2"

Question 839

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

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

871 791 721 661 611 ?

  1. AOption (a)

    501

  2. BOption (b)

    539

  3. COption (c)

    523

  4. DOption (d)

    571

View answer & explanation

Correct answer

Answer: (d)D.

571

Why this answer is correct

The logic followed here is:

 

  • 871 − 80 = 791
  • 791 − 70 = 721
  • 721 − 60 = 661
  • 661 − 50 = 611
  • 611 − 40 = 571

Thus, the missing term in the series is 571.

Hence, the correct answer is 'Option 4';

Question 840

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 engineers are designers. All designers are creators.

Conclusions:

(I) All creators are engineers.

(II) Some engineers are creators.

  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: (b)B.

Only conclusion (II) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

(I) All creators are engineers - Doesn't follows (Some creators are engineers and some engineers are creators but all creators are engineers is may be possible but not definite. Hence, it is false)

(II) Some engineers are creators - Follows  (Some creators are engineers and some engineers are creators. Hence, uit is true)

Only conclusion (II) follows.

Hence, the correct answer is " Option 2"
