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

80 ? 89 98 110 125

  1. AOption (a)

    85

  2. BOption (b)

    82

  3. COption (c)

    83

  4. DOption (d)

    84

View answer & explanation

Correct answer

Answer: (c)C.

83

Why this answer is correct

The logic follows here, 

  • 80 + 3 = 83
  • 83 + 6 = 89
  • 89 + 9 = 98
  • 98 + 12 = 110
  • 110 + 15 = 125

Hence, the correct answer is "Option 3"

View answer & explanation

Correct answer

Answer: (d)D.

YEAR - AYER - RAEY

Why this answer is correct

The logic follows here, 

JAMS − MJAS − SMAJ,

Applying same logic for YEAR - AYER - RAEY, 

Hence, the correct answer is " Option 4"

Question 953

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

In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Select the set in which the numbers are related in the same way as are the numbers of the following sets.

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding / subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

  1. AOption (a)

    138, 153

  2. BOption (b)

    56, 72

  3. COption (c)

    39, 64

  4. DOption (d)

    97, 111

View answer & explanation

Correct answer

Answer: (a)A.

138, 153

Why this answer is correct

The logic followed here is:

Logic: Second Number = First Number + 15

For the first pair 89 : 104

⇒ 89 + 15 = 104

For the second pair 157 : 172

⇒ 157 + 15 = 172

Applying the same logic to the options:

In Option 1

138 : 153

⇒ 138 + 15 = 153

Hence, the correct answer is 'Option 1'.

Question 955

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

Based on the English 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)

    KMP

  2. BOption (b)

    QSV

  3. COption (c)

    DFJ

  4. DOption (d)

    FHK

View answer & explanation

Correct answer

Answer: (c)C.

DFJ

Why this answer is correct

The position and positional values of English Alphabets are:

KMP

QSV

FHK

DFJ

 

This cluster does not follow the (+2, +3) pattern.

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

Hence, the correct answer is 'Option 3'.

Question 956

  4. DOption (d)

    YWU−RQP

View answer & explanation

Correct answer

Answer: (a)A.

YXW−SRQ

Why this answer is correct

The logic followed here is:

VUT-PON:

 

TSR-NML:

Applying the same logic, 

The resulting pair is YXW-SRQ.

Hence, the correct answer is "option 1"

Question 957

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

Read the given statements and conclusions carefully. You have to take the given statements to be true even if they seem to be at variance from commonly known facts. You have to decide which conclusions logically follow/s from the given statements.

Statements: Some pens are markers. All markers are stands.

Conclusion (I) : Some pens are stands

Conclusion (II) : All stands are markers

  1. AOption (a)

    Only conclusion (I) follows

  2. BOption (b)

    Only conclusion (II) follows

  3. COption (c)

    Both conclusions (I) and (II) follow

  4. DOption (d)

    Neither conclusion (I) nor (II) follows

View answer & explanation

Correct answer

Answer: (a)A.

Only conclusion (I) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

(I) Some pens are stands -  Follow

(Some pens are markers, and all markers are Stand. Hence, Some pens are stands is true)

(II) All stands are markers - Doesn't follow

All markers are stands, but all stands are markers is may be possible but not definite. Hence, it is false)

Only conclusion (I) follows

Hence, the correct answer is " Option 1"

Question 958

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

Which two numbers should be interchanged to make the given equation correct?

(6 × 14) ÷ 2 + 18 × 4 - 28 ÷ 7 + 34 = 87

  1. AOption (a)

    4 and 2

  2. BOption (b)

    14 and 18

  3. COption (c)

    6 and 4

  4. DOption (d)

    7 and 4

View answer & explanation

Correct answer

Answer: (a)A.

4 and 2

Why this answer is correct

The logic followed here is ,

BODMAS Table: 

Given Equation:  (6 × 14) ÷ 2 + 18 × 4 - 28 ÷ 7 + 34 = 87

Interchanging 4 and 2 and applying BODMAS rule,

= 84 ÷ 4 + 18 × 2 − 28 ÷ 7 + 34

= 21 + 18 × 2 − 4 + 34

= 21 + 36 − 4 + 34

= 21 + 36 + 34 − 4 

= 91− 4 

= 87 

Since LHS = RHS, the equation is correct after interchanging these numbers.

Hence, the correct answer is "option 1"

Why this answer is correct

Given :  Seven people, S, T, I, C, K, E and R, are sitting in a row, facing north.

  1. Only two people sit between C and I.
  2. Only K sits to the right of E.
  3. Only one person sits between I and E.
  4. S sits at some place to the right of R but at some place to the left of T.

Final Arrangement:

Therefore, T sits third from the right end of the line.

Hence, the correct answer is "option 1"
