Question 241

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

In a certain code language,

A x B means ‘A is the father of B’,

A ≠ B means ‘A is the son of B’,

A ÷ B means ‘A is the daughter of B’ and

A ₹ B means ‘A is the sister of B’.

Based on the above, how is C related to M if 'C ÷ D ₹ E ≠ L x M'?

  1. AOption (a)

    Mother's mother

  2. BOption (b)

    Daughter

  3. COption (c)

View answer & explanation

Correct answer

Answer: (c)C.

Sister's daughter

Why this answer is correct

Family Chart:

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

Symbol×≠÷₹
MeaningFatherSonDaughterSister

 

Given : C ÷ D ₹ E ≠ L × M

  

Based on the tree, L is the father of E, D, and M. D is the sister of M, and C is the daughter of D. Therefore, C is the Sister's daughter of M.

Hence, the correct answer is 'Option 3'.

Answer: (b)B.

347

Why this answer is correct

The logic follows here, 

Logic: The difference between the consecutive terms in the series is a multiple of 17.

  • 92 + 17 = 109
  • 109 + 34 = 143
  • 143 + 51 = 194
  • 194 + 68 = 262
  • 262 + 85 = 347

Hence, the correct answer is "option 2".

  3. COption (c)

    114

  4. DOption (d)

    120

View answer & explanation

Correct answer

Answer: (c)C.

114

Why this answer is correct

The logic follows here, 

Logic: Sum of opposite positional values × 2.

ZCKU

  • Sum of opposite positional values = 1 + 24 + 16 + 6 = 47
  • Code = 47 × 2 = 94

 

SAPI 

  • Sum of opposite positional values = 8 + 26 + 11 + 18 = 63
  • Code = 63 × 2 = 126

 

Applying the same logic GXRB,

  • Sum of opposite positional values = 20 + 3 + 9 + 25 = 57
  • Code = 57 × 2 = 114

 

Hence, the correct answer is “Option 3”.

  3. COption (c)

    55

  4. DOption (d)

    52

View answer & explanation

Correct answer

Answer: (a)A.

76

Why this answer is correct

The logic follows here, 

Logic: Sum of opposite positional values of letters − 5.

For NHJCR, 

  • Sum of reverse positional values = 13 + 19 + 17 + 24 + 9 = 82
  • Code = 82 − 5 = 77

 

For QETLO,

  • Sum of reverse positional values = 10 + 22 + 7 + 15 + 12 = 66
  • Code = 66 − 5 = 61

 

Applying the same logic PHASJ:

  • Sum of reverse positional values = 11 + 19 + 26 + 8 + 17 = 81
  • Code = 81 − 5 = 76

 

Hence, the correct answer is "option 1"
