View answer & explanation

Correct answer

Answer: (b)B.

OSF

Why this answer is correct

The logic followed here is,

Logic: In the given series, each letter in a term is shifted forward by 3 positions in the English alphabetical order

The next term in the series is OSF.

Hence,the correct answer is "option 2"

Question 192

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

In a certain code language, "SFOR" is coded as "116" and "WILA" is coded as "90".

What is the code for "GMVC" in that given language?

  1. AOption (a)

    90

  2. BOption (b)

    110

  3. COption (c)

    120

  4. DOption (d)

    95

View answer & explanation

Correct answer

Answer: (a)A.

90

Why this answer is correct

The logic followed here is.

Logic: The code for a word is determined by summing the positional values of its letters and then multiplying the sum by 2.

For SFOR 

  • Sum of positional values = 19 + 6 + 15 + 18 = 58
  • Code = 58 × 2 = 116

 

For WILA, 

  • Sum of positional values = 23 + 9 + 12 + 1 = 45
  • Code = 45 × 2 = 90

 

For GMVC:

  • Sum of positional values = 7 + 13 + 22 + 3 = 45
  • Code = 45 × 2 = 90

 

Hence, the correct answer is "option 1"

Question 193

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

In a certain code language,

A + B means ‘A is the husband of B’,

A - B means ‘A is the brother of B’,

A × B means ‘A is the mother of B’, and

A ÷ B means ‘A is the sister of B’.

Based on the above, how is G related to R if ‘G ÷ H + I × T - R’?

  1. AOption (a)

    Mother’s sister

  2. BOption (b)

    Father’s sister

  3. COption (c)

    Brother’s wife

  4. DOption (d)

    Father’s mother

View answer & explanation

Correct answer

Answer: (b)B.

Father’s sister

Why this answer is correct

Family Chart 

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

Symbol+−×÷
MeaningHusbandBrotherMotherSister

 

Given : G ÷ H + I × T − R

​From the tree, H is the father of R, and G is the sister of H. Therefore, G is the Father's sister of R.

Hence, the correct answer is 'Option 2'.

Question 194

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.)

  1. AOption (a)

    JE - MK

  2. BOption (b)

    HC - GB

  3. COption (c)

    LG - KF

  4. DOption (d)

    NI - MH

View answer & explanation

Correct answer

Answer: (a)A.

JE - MK

Why this answer is correct

The logic followed here is

Logic: In each letter-cluster pair (except the odd one), the second cluster is formed by subtracting 1 

For JE – MK,

For HC – GB,

For LG – KF,

For NI – MH,

Therefore, the letter-cluster pair that is different from the others is JE – MK.

Hence, the correct answer is 'Option 1'.

Question 195

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.)

  2. BOption (b)

    (7, 3, 20)

  3. COption (c)

  4. DOption (d)

    (3, 5, 15)

View answer & explanation

Correct answer

Answer: (c)C.

(1, 7, 8)

Why this answer is correct

The logic followed here is:

Logic: (First Number × Second Number) + 1 = Third Number

For the first set (5, 3, 16)

⇒ (5 × 3) + 1

⇒ 15 + 1 = 16.

For the second set (6, 3, 19)

⇒ (6 × 3) + 1

⇒ 18 + 1 = 19.

Applying the same logic to Option 3

(1, 7, 8)

⇒ (1 × 7) + 1

⇒ 7 + 1 = 8.

Hence, the correct answer is 'Option 3'.

Question 196

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

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

217 190 165 142 121 102 ?

  1. AOption (a)

    85

  2. BOption (b)

    92

  3. COption (c)

    90

  4. DOption (d)

    87

View answer & explanation

Correct answer

Answer: (a)A.

85

Why this answer is correct

The logic follows here, 

  • 217 − 27= 190
  • 190 − 25 = 165
  • 165 − 23= 142
  • 142 − 21= 121
  • 121 − 19= 102
  • 102 - 17=  85

Missing value = 102 − 17 = 85

Hence, the correct answer is "option 1"

Question 197

  3. COption (c)

    60

  4. DOption (d)

    55

View answer & explanation

Correct answer

Answer: (d)D.

55

Why this answer is correct

The logic follows here, 

  • 43 + 12 = 55
  • 55 − 24 = 31
  • 31 + 36 = 67
  • 67 − 48 = 19
  • 19 + 60 = 79

Hence, the correct answer is "option 4"

Question 198

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

Based on the English alphabetical order, three of the following four are alike in a certain way and thus form a group.

Hence, the correct answer is "option 3"

Question 199

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 eggs are squares. Some crows are eggs.

Conclusion (I): Some squares are crows.

Conclusion (II): All eggs are crows.

  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:

Conclusion

(I) Some squares are crows — Follow (All eggs are squares and some crows are eggs. Some squares are crows is true)

(II) All eggs are crows - Does not follow (some crows are eggs that means some eggs are also crows but all eggs are crows is  may be possible but not definite. Hence, it is false)

Therefore, only conclusion (I) follows.

Hence, the correct answer is "Option 3".

  4. DOption (d)

    404 D 4 D 15 C 50 A 8

View answer & explanation

Correct answer

Answer: (a)A.

404 A 4 D 15 C 50 B 8

Why this answer is correct

The logic follows here, 

BODMAS Table: 

Now, replacing the symbols with their meanings ‘C = +’, ‘A = ÷’, ‘D = −’, ‘B = ×’, 

Applying the BODMAS rule,

Option 1)  404 A 4 D 15 C 50 B 8

⇒ 404 ÷ 4 - 15 + 50 × 8

⇒101- 15 + 50 × 8

⇒101 + 400 - 15

⇒ 501 - 15

⇒486

Hence, the correct answer is "option 1"
