Correct answer

Answer: (b)B.

One

Why this answer is correct

Given: G L Y N J Z U Q M F D E U S A B Y D V X P

Required Conditions: Vowel - Consonant - Vowel

Left  G L Y N J Z U Q M F D E U S A B Y D V X P  Right

  1. AOption (a)

    FEC−DDA

  2. BOption (b)

    FEC−EDB

  3. COption (c)

    FDA−EDB

  4. DOption (d)

View answer & explanation

Correct answer

Answer: (b)B.

FEC−EDB

Why this answer is correct

The logic follows here, 

Logic: Each letter in the first term of the pair is shifted one position backward (positional value − 1) in the English alphabetical series to obtain the corresponding letter in the second term.

For MLJ : LKI 

 

For XWU : WVT

 

Applying same logic  FEC : EDB ,

Hence, the correct answer is "Option 2"

Question 328

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

GILF is related to NPSM in a certain way based on the English alphabetical order. In the same way, JLOI is related to QSVP.

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

  1. AOption (a)

    TVYS

  2. BOption (b)

    VTYS

  3. COption (c)

    TVSY

  4. DOption (d)

    VTSY

View answer & explanation

Correct answer

Answer: (a)A.

TVYS

Why this answer is correct

The logic followed in this pattern is a consistent alphabetical shift where each letter is moved forward by 7 positions in the English alphabetical order.

For 'GILF' related to 'NPSM':

G(7)I(9)L(12)F(6)
+7 ↓+7 ↓+7 ↓+7 ↓
N(14)P(16)S(19)M(13)

For 'JLOI' related to 'QSVP':

J(10)L(12)O(15)I(9)
+7 ↓+7 ↓+7 ↓+7 ↓
Q(17)S(19)V(22)P(16)

Applying the same logic to 'MORL':

M(13)O(15)R(18)L(12)
+7 ↓+7 ↓+7 ↓+7 ↓
T(20)V(22)Y(25)S(19)

Thus, MORL is related to TVYS.

Hence, the correct answer is 'Option 1'.

Question 329

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

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

11 29 51 81 123 ?

  1. AOption (a)

    190

  2. BOption (b)

    195

  3. COption (c)

    181

  4. DOption (d)

    185

View answer & explanation

Correct answer

Answer: (c)C.

181

Why this answer is correct

The logic follows here, 

  • 11 + 18 = 29
  • 29 + 22 = 51
  • 51 + 30 = 81
  • 81 + 42 = 123
  • 123 + 58 = 181

 

Thus, the missing term in the series is 181.

Hence, the correct answer is 'Option 3';

Question 330

View answer & explanation

Correct answer

Answer: (d)D.

18

Why this answer is correct

The logic follows here, 

Symbol Meaning:

PQRD
÷×+−

Given Equation: 24 D 32 P 8 R 26 Q 2 D 54 = ?

Replacing the letters with signs and applying BODMAS rule,

= 24 − 32 ÷ 8 + 26 × 2 − 54

= 24 − 4 + 26 × 2 − 54

 

= 24 − 4 + 52 − 54

= 24 + 52 − 54 − 4 

= 76 - 58

= 18

Hence, the correct answer is "Option 4"
