Question 98

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)

    FE−IH

  2. BOption (b)

    LK−ON

  3. COption (c)

    CB−FE

  4. DOption (d)

    KJ−MO

View answer & explanation

Correct answer

Answer: (d)D.

KJ−MO

Why this answer is correct

The logic followed here is

Logic: The first letter of the second cluster is 3 positions ahead of the first letter of the first cluster, and the letters in each cluster are in consecutive reverse alphabetical order.

FE-IH,

LK-ON,

CB-FE,

KJ-MO,

Therefore, the letter-cluster pair that is different from the others is KJ-MO.

Hence, the correct answer is 'Option 4'.

    18

  4. DOption (d)

    16

View answer & explanation

Correct answer

Answer: (b)B.

11

Why this answer is correct

The logic follows here,

  • 7 + 4 = 11
  • 11 + 8 = 19
  • 19 + 12 = 31
  • 31 +16 = 47
  • 47 + 18 = 67

The missing value is 11.

Hence, the correct answer is "Option 2"

Question 100

BFGJ is related to GKLO in a certain way based on the English alphabetical order. In the same way, HKMN is related to MPRS.

To which of the following is ORTU related, following the same logic?

  1. AOption (a)

    QEIY

  2. BOption (b)

    TWYZ

  3. COption (c)

    SVXY

  4. DOption (d)

    UXZA

View answer & explanation

Correct answer

Answer: (b)B.

TWYZ

Why this answer is correct

The logic followed in this pattern is a consistent alphabetical shift of +5 for each letter.

For 'BFGJ' related to 'GKLO':

B(2)F(6)G(7)J(10)
+5 ↓+5 ↓+5 ↓+5 ↓
G(7)K(11)L(12)O(15)

For 'HKMN' related to 'MPRS':

H(8)K(11)M(13)N(14)
+5 ↓+5 ↓+5 ↓+5 ↓
M(13)P(16)R(18)S(19)

Applying the same logic to 'ORTU':

O(15)R(18)T(20)U(21)
+5 ↓+5 ↓+5 ↓+5 ↓
T(20)W(23)Y(25)Z(26)

Thus, ORTU is related to TWYZ.

Hence, the correct answer is 'Option 2'.
