Question 421

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

In a certain code language,

A ≠ B means ‘A is the sister of B’

A * B means ‘A is the father of B’

A ; B means ‘A is the son of B’

A + B means ‘A is the wife of B’

Based on the above, how is F related to O if 'F ≠ G ; H + M * O'?

  1. AOption (a)

    Husband's father's sister

  2. BOption (b)

    Brother's wife

  3. COption (c)

    Sister

  4. DOption (d)

    Wife

View answer & explanation

Correct answer

Answer: (c)C.

Sister

Why this answer is correct

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≠*;+
MeaningSisterFatherSonWife

Given:  'F ≠ G ; H + M * O'

Based on the family tree, H and M are a married couple with three children: F, G, and O. Since F is female and they all share the same parents, F is the sister of O.

Hence, the correct answer is "Option 3"

Question 422

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

LEMO is related to RJST in a certain way based on the English alphabetical order. In the same way, JYKI is related to PDQN.

To which of the following options is BNCX related, following the same logic?

  1. AOption (a)

    HSIC

  2. BOption (b)

    CISH

  3. COption (c)

    SHIK

  4. DOption (d)

    KISH

View answer & explanation

Correct answer

Answer: (a)A.

HSIC

Why this answer is correct

The logic followed in this pattern is a series of alphabetical shifts where each letter is moved forward by a specific number of positions.

For 'LEMO' related to 'RJST':

L(12)E(5)M(13)O(15)
+6 ↓+5 ↓+6 ↓+5 ↓
R(18)J(10)S(19)T(20)

For 'JYKI' related to 'PDQN':

J(10)Y(25)K(11)I(9)
+6 ↓+5 ↓+6 ↓+5 ↓
P(16)D(4)Q(17)N(14)

Applying the same logic to 'BNCX':

B(2)N(14)C(3)X(24)
+6 ↓+5 ↓+6 ↓+5 ↓
H(8)S(19)I(9)C(3)

Thus, BNCX is related to HSIC following the pattern +6, +5, +6, +5.

Hence, the correct answer is 'Option 1'.

Question 423

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

Based on the alphabetical order, three of the following four 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 man out is not based on the number of consonants/vowels or their position in the letter cluster.)

  1. AOption (a)

    XBA

  2. BOption (b)

    ZDC

  3. COption (c)

    DHG

  4. DOption (d)

    HMK

View answer & explanation

Correct answer

Answer: (d)D.

HMK

Why this answer is correct

The logic follows here, 

Logic: 1st letter + 4 = 2nd letter; 2nd letter − 1 = 3rd letter.

For XBA,

For  ZDC,

For  DHG,

For  HMK,

This letter cluster does not follow the rule.

Therefore, the letter cluster that is different from the others is HMK.

Hence, the correct answer is 'Option 4'.

    YCA

  4. DOption (d)

    BGD

View answer & explanation

Correct answer

Answer: (d)D.

BGD

Why this answer is correct

The logic follows here, 

Logic: Second letter = First letter + 4; Third letter = Second letter − 2.

For ZDB,

For  VZX,

For YCA,

For  BGD,

  

 

Therefore, the letter cluster that is different from the others is BGD.

Hence, the correct answer is 'Option 4'.

Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.

Statements: All apples are fruits. Some fruits are sweet.

Conclusions

(I) Some apples are sweet.

(II) All fruits are apples.

  1. AOption (a)

    Both conclusions (I) and (II) follow

  2. BOption (b)

    Only conclusion (II) follows

  3. COption (c)

    Neither conclusion (I) nor (II) follows

  4. DOption (d)

    Only conclusion (I) follows

View answer & explanation

Correct answer

Answer: (c)C.

Neither conclusion (I) nor (II) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

Conclusion

(I) Some apples are sweet -  Doesn't follow

(There is no direct relation between apples and sweets; maybe it is possible but not definite. Hence, it is false.)

(II) All fruits are apples - Doesn't follow

(All apples are fruit and all fruits are apples may be possible but not definite. Hence, it is false)

Neither conclusion (I) nor (II) follows

Hence, the correct answer is "Option 3"

Correct answer

Answer: (d)D.

48

Why this answer is correct

BODMAS Table:

Given equation: 1 ÷ 1 × 1 + 2 − 49 = ?

Sign Interchange Mapping:

Original Sign÷×+−
Interchanged Sign×÷−+

 

Applying the interchanges to the expression and applying BODMAS rule:

= 1 × 1 ÷ 1 − 2 + 49

= 1 × 1 − 2 + 49

= 1 + 49 − 2

= 50 − 2

= 48

Hence, the correct answer is "option 4"

View answer & explanation

Correct answer

Answer: (a)A.

260

Why this answer is correct

The logic follows here, 

  • 232 + 28 = 260
  • 260 − 56 = 204
  • 204 + 84 = 288
  • 288 − 112 = 176
  • 176 + 140 = 316

By following this pattern, the missing number in the series is 260.

Hence, the correct answer is "option 1"

Correct answer

Answer: (b)B.

 (182, 164, 352)

Why this answer is correct

The logic followed here is:

Logic: (First Number + Second Number) + 6 = Third Number

For the first set (156, 204, 366)

⇒ (156 + 204) + 6

⇒ 360 + 6 = 366.

For the second set (150, 162, 318)

⇒ (150 + 162) + 6

⇒ 312 + 6 = 318.

Applying the same logic to Option 2

(182, 164, 352)

⇒ (182 + 164) + 6

⇒ 346 + 6 = 352.

Hence, the correct answer is 'Option 2'.
