View answer & explanation

Correct answer

Answer: (a)A.

Mother's mother

Why this answer is correct

Family Chart:

Let us first analyze the given relations between the family members:

Therefore, A is the mother of O, who is the mother of D. This makes A the maternal grandmother of D, which is the Mother's mother.

Hence, the correct answer is "Option 1".

Question 902

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)

    Son's wife's father's sister

  2. BOption (b)

    Wife's father's brother

  3. COption (c)

    Son's wife's brother's son

  4. DOption (d)

    Son's wife's father's brother

View answer & explanation

Correct answer

Answer: (d)D.

Son's wife's father's brother

Why this answer is correct

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

Symbol÷#+&
MeaningSonWifeBrotherFather
of B

Given : S + D & R # Y ÷ H

 

​Therefore, S is the brother of D, who is the father of R, and R is the wife of Y (who is the son of H) → S is the Son's wife's father's brother of H.

Hence, the correct answer is 'Option 4'.

Question 903

Answer: (a)A.

FXN 52

Why this answer is correct

The logic follows here,

The next cluster-number pair in the series is FXN 52.

Hence, the correct answer is "option 1".

Question 904

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 letter-cluster pair 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)

    LG – SC

  2. BOption (b)

    QM – XJ

  3. COption (c)

    HP – OM

  4. DOption (d)

    RD – YA

View answer & explanation

Correct answer

Answer: (a)A.

LG – SC

Why this answer is correct

The logic follows here, 

LG - SC,

QM - XJ,

HP - OM,

RD - YA,

Therefore, the letter-cluster pair that is different from the others is LG - SC.

Hence, the correct answer is 'Option 1'.

Why this answer is correct

Seven people, A, B, C, D, E, F and G, are sitting in a row, facing north.

  1. F sits third to the left of A and F sits third to the right of D.
  2. E sits third to the left of B and B sits to the immediate left of G

The final arrangement of people facing North is:

Hence, the correct answer is " Option 1"

Question 906

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

In a certain code language, "JCPV" is coded as "51" and "DYSF" is coded as "48". What is the code for "HTOB" in that given language?

  1. AOption (a)

    50

  2. BOption (b)

    49

  3. COption (c)

    53

  4. DOption (d)

    57

View answer & explanation

Correct answer

Answer: (d)D.

57

Why this answer is correct

The logic follows here, 

For JCPV is coded as 51,

  • Sum of opposite positional values = 17 + 24 + 11 + 5 = 57
  • Code = 57 − 6 = 51

 

DYSF is coded as 48,

  • Sum of opposite positional values = 23 + 2 + 8 + 21 = 54
  • Code = 54 − 6 = 48

 

Similarly, let's find the code for HTOB:

  • Sum of opposite positional values = 19 + 7 + 12 + 25 = 63
  • Code = 63 − 6 = 57

 

Hence, the correct answer is "option 4"

Question 907

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

Select the pair which follows the same pattern as that followed by the two pairs given below. Both pairs follow the same pattern.

DCF−GFI

YXA−BAD

  1. AOption (a)

    TRT−WVY

  2. BOption (b)

    TSV−VVX

  3. COption (c)

    TRT−VUX

  4. DOption (d)

    RQT−UTW

View answer & explanation

Correct answer

Answer: (d)D.

RQT−UTW

Why this answer is correct

The logic follows here, 

For DCF : GFI

 

For YXA : BAD

 

Similarly, for the pair RQT : UTW

The pattern is consistent across all pairs where each character is incremented by 3.

Hence, the correct answer is "Option 4"

Answer: (d)D.

Five

Why this answer is correct

Given: A, B, D, J, O, T and Z are sitting around a circular table facing the center.

  1. Only two people sit between A and Z when counted from the left of A.
  2. J is an immediate neighbor of Z.
  3. Only one person sits between J and O when counted from the left of J.
  4. O is not an immediate neighbor of Z.
  5. T sits immediately to the left of D

The Final Arrangement is, 

 

Five  people sit between B and O when counted from the left of O

Hence, the correct answer is "Option 4"

Question 910

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

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