Question 151

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)

    OH-KM

  2. BOption (b)

    QJ-MO

  3. COption (c)

    LE-HJ

  4. DOption (d)

    JC-FG

View answer & explanation

Correct answer

Answer: (d)D.

JC-FG

Why this answer is correct

The logic followed here is,

Logic: First letter of the second cluster = First letter of the first cluster − 4; Second letter of the second cluster = Second letter of the first cluster + 5.

OH-KM,

QJ-MO,

LE-HJ

JC-FG,

This pair does not follow the rule because the second letter transformation is +4 instead of +5.

Therefore, the letter-cluster pair that is different from the others is JC-FG.

Hence, the correct answer is 'Option 4'.

Question 153

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

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.

Statement: All Chickens are Quails. All Quails are Pigeons.

Conclusion (I): No Pigeons are Chickens.

Conclusion (II): Some Pigeons are Chickens.

  1. AOption (a)

    Neither conclusion (I) nor (II) follows

  2. BOption (b)

    Only conclusion (II) follows

  3. COption (c)

    Only conclusion (I) follows

  4. DOption (d)

    Both conclusions (I) and (II) follow

View answer & explanation

Correct answer

Answer: (b)B.

Only conclusion (II) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

 

Conclusion

(I) No Pigeons are Chickens - Does not follow (All Chickens are Quails and all Quails are Pigeons that no Pigeons are Chickens is false)

(II) Some Pigeons are Chickens - **Follow (**All Chickens are Quails and all Quails are Pigeons.So, Some pigeons are chickens is true)

Only conclusion (II) follows

Hence, the correct answer is "Option 2".

Question 156

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

If ‘+’ means ‘−’, ‘−’ means ‘×’, ‘×’ means ‘÷’, ‘÷’ means ‘+’, then what will come in place of the question mark (?) in the following equation?

17 − 3 ÷ 8 + 21 × 3 = ?

  1. AOption (a)

    49

  2. BOption (b)

    50

  3. COption (c)

    52

  4. DOption (d)

    51

View answer & explanation

Correct answer

Answer: (c)C.

52

Why this answer is correct

BODMAS rule:

Given : 17 − 3 ÷ 8 + 21 × 3 = ?

After ‘+’ means ‘−’, ‘−’ means ‘×’, ‘×’ means ‘÷’, ‘÷’ means ‘+’,are interchanged then,

17 × 3 + 8 − 21 ÷ 3 = ?

Perform operations according to BODMAS:

⇒ 17 × 3 + 8 − 21 ÷ 3 

⇒ 17 × 3 + 8 − 7

⇒ 51 + 8 − 7

⇒ 59 - 7 

⇒52

Hence,the correct answer is option 3

Question 160

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

SMAL is related to VQFR in a certain way based on the English alphabetical order. In the same way, ECUJ is related to HGZP. To which of the following options is NOJB related, following the same logic?

  1. AOption (a)

    QSIO

  2. BOption (b)

    QSHO

  3. COption (c)

    QOSH

  4. DOption (d)

    QSOH

View answer & explanation

Correct answer

Answer: (d)D.

QSOH

Why this answer is correct

The logic followed in this pattern is based on incremental alphabetical shifts for each letter of the word.

For 'SMAL' related to 'VQFR':

S(19)M(13)A(1)L(12)
+3 ↓+4 ↓+5 ↓+6 ↓
V(22)Q(17)F(6)R(18)

For 'ECUJ' related to 'HGZP':

E(5)C(3)U(21)J(10)
+3 ↓+4 ↓+5 ↓+6 ↓
H(8)G(7)Z(26)P(16)

Applying the same logic to 'NOJB':

N(14)O(15)J(10)B(2)
+3 ↓+4 ↓+5 ↓+6 ↓
Q(17)S(19)O(15)H(8)

Thus, NOJB is related to QSOH.

Hence, the correct answer is 'Option 4'.
