Correct answer

Answer: (d)D.

21

Why this answer is correct

Preparing the family tree diagram by using the following symbols:

As per the given information:

Deciphering the signs:

ABCD
÷×+−

Given Equation: 7 A 7 C 20 B 2 = ? C 20

Applying the conditions and BODMAS rule:

= 7 ÷ 7 + 20 × 2 = ? + 20

= 1 + 20 × 2 = ? + 20

= 1 + 40 = ? + 20

= 41 = ? + 20

? = 41 − 20

? = 21

Hence, the correct answer is "option 4"

Question 415

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)

    IJ - OP

  2. BOption (b)

    MJ - LP

  3. COption (c)

    CD - IJ

  4. DOption (d)

    ST - YZ

View answer & explanation

Correct answer

Answer: (b)B.

MJ - LP

Why this answer is correct

The logic follows here, 

For IJ - OP,

For  MJ - LP,

For  CD - IJ,

For  ST - YZ,

Therefore, the letter-cluster pair that is different from the others is MJ - LP.

Hence, the correct answer is 'Option 2'.

Question 416

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

LOSM is related to QTXR in a certain way based on the English alphabetical order. In the same way, ILPJ is related to NQUO. To which of the following is FIMG related, following the same logic?

  1. AOption (a)

    KNRL

  2. BOption (b)

    NKRL

  3. COption (c)

    NKLR

  4. DOption (d)

    KNLR

View answer & explanation

Correct answer

Answer: (a)A.

KNRL

Why this answer is correct

The logic followed in this pattern is a consistent alphabetical shift where each letter is moved forward by 5 positions in the English alphabetical order.

For 'LOSM' related to 'QTXR':

L(12)O(15)S(19)M(13)
+5 ↓+5 ↓+5 ↓+5 ↓
Q(17)T(20)X(24)R(18)

For 'ILPJ' related to 'NQUO':

I(9)L(12)P(16)J(10)
+5 ↓+5 ↓+5 ↓+5 ↓
N(14)Q(17)U(21)O(15)

Applying the same logic to 'FIMG':

F(6)I(9)M(13)G(7)
+5 ↓+5 ↓+5 ↓+5 ↓
K(11)N(14)R(18)L(12)

Thus, FIMG is related to KNRL.

Hence, the correct answer is 'Option 1'.

Question 417

  1. AOption (a)

    Three

  2. BOption (b)

    One

  3. COption (c)

    Two

  4. DOption (d)

    Zero

View answer & explanation

Correct answer

Answer: (b)B.

One

Why this answer is correct

The logic followed here is:

Given Word: NOTFERN.

NOTFERN
− 1+ 1− 1− 1+ 1− 1− 1
MPSEFQM

The new group of letters formed is: M, P, S, E, F, Q, M.

 

There is one letter M that appears exactly twice in the new group.

Hence, the correct answer is "Option 2"

Question 418

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

In a certain code language,

A x B means ‘A is the mother of B’,

A ≠ B means ‘A is the wife of B’,

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

A ₹ B means ‘A is the father of B’.

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

  1. AOption (a)

    Wife's brother's wife

  2. BOption (b)

    Wife's mother

  3. COption (c)

    Brother's wife

  4. DOption (d)

Preparing the family tree diagram by using the following symbols:

As per the given information:

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

Symbol×≠÷₹
MeaningMotherWifeDaughterFather

Given: C ≠ D ₹ E × L ÷ M

From the above steps, C is the mother of E, and E is the wife of M. Therefore, C is the Wife's mother of M.

Hence, the correct answer is "Option 2".

Question 419

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

What will come in place of ‘?’ in the following equation, if ‘+’ and ‘-‘ are interchanged and ‘x’ and ‘÷’ are interchanged?

12 ÷ 4 + 9 x 3 - 8 = ?

  1. AOption (a)

    35

  2. BOption (b)

    53

  3. COption (c)

    39

  4. DOption (d)

    44

View answer & explanation

Correct answer

Answer: (b)B.

53

Why this answer is correct

BODMAS Table:

Given equation: 12 ÷ 4 + 9 × 3 − 8 = ?

Sign Interchange:

Original Sign÷+×−
New Sign×−÷+

 

After interchanging the signs, and applying the BODMAS rule

12 × 4 − 9 ÷ 3 + 8 = ?

= 12 × 4 − 9 ÷ 3 + 8

= 12 × 4 − 3 + 8

= 48 + 8 − 3

= 56 − 3

= 53

Hence, the correct answer is "option 2"
