Question 143

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.)

  4. DOption (d)

    58, 120

View answer & explanation

Correct answer

Answer: (c)C.

62, 126

Why this answer is correct

The logic followed here is:

Logic: Second Number = (First Number × 2) + 2

For the first set 54, 110

⇒ (54 × 2) + 2

⇒ 108 + 2 = 110.

For the second set 56, 114

⇒ (56 × 2) + 2

⇒ 112 + 2 = 114.

Applying the same logic

62, 126

⇒ (62 × 2) + 2

⇒ 124 + 2 = 126.

Hence, the correct answer is "Option 3".

Question 146

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

Select the triad which follows the same pattern as that followed by the two triads given below. Both triads follow the same pattern.

RN-TP-VY

PL-RN-TW

  1. AOption (a)

    MJ-PL-RV

  2. BOption (b)

    MJ-PK-RV

  3. COption (c)

    NJ-PL-RU

  4. DOption (d)

    NJ-PL-RV

View answer & explanation

Correct answer

Answer: (c)C.

NJ-PL-RU

Why this answer is correct

The logic followed in these triads is based on the positional values of the English alphabets. The pattern for each triad is as follows:

For the triad 'RN-TP-VY':

R(18)N(14)
+2 ↓+2 ↓
T(20)P(16)
+2 ↓+9 ↓
V(22)Y(25)

For the triad 'PL-RN-TW':

P(16)L(12)
+2 ↓+2 ↓
R(18)N(14)
+2 ↓+9 ↓
T(20)W(23)

Applying the same logic to the options:

N(14)J(10)
+2 ↓+2 ↓
P(16)L(12)
+2 ↓+9 ↓
R(18)U(21)

Thus, the triad NJ-PL-RU follows the same pattern.

Hence, the correct answer is 'Option 3'.

Question 147

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

What will come in place of the question mark (?) in the following equation if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?

805 ÷ 2 + 26 − 1203 × 3 = ?

  1. AOption (a)

    1588

  2. BOption (b)

    1985

  3. COption (c)

    1598

  4. DOption (d)

    1895

View answer & explanation

Correct answer

Answer: (b)B.

1985

Why this answer is correct

Given : 805 ÷ 2 + 26 − 1203 × 3 = ?

After '+' and ‘-' are interchanged and '×' and ‘÷' are interchanged then,

⇒805 × 2 - 26 + 1203 ÷ 3 = ?

⇒805 × 2 - 26 + 401 = ?

⇒1610 + 401 - 26 = ?

⇒ 2011 - 26 = ?

⇒ 1985 = ?

Hence, "Option 2" is the correct answer.

Question 148

  3. COption (c)

    JU62

  4. DOption (d)

    IU63

View answer & explanation

Correct answer

Answer: (a)A.

IT62

Why this answer is correct

The logic follows here, 

Logic: (First Letter − 2), (Second Letter + 2), and (Number + 9).

The missing term in the series is IT62.

Hence, the correct answer is "option 1"

Question 149

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?

18 − 3 ÷ 9 + 15 × 3 = ?

  1. AOption (a)

    50

  2. BOption (b)

    57

  3. COption (c)

    58

  4. DOption (d)

    49

View answer & explanation

Correct answer

Answer: (c)C.

58

Why this answer is correct

BODMAS Rule:

According to the question, the signs are interchanged as follows:

Original Symbol+−×÷
New Symbol−×÷+

Now, given the equation: 18 − 3 ÷ 9 + 15 × 3 = ?

After interchanging the specified signs, the new equation is:

18 × 3 + 9 - 15 ÷ 3 = ?

Perform operations according to BODMAS:

⇒18 × 3 + 9 - 15 ÷ 3 

⇒18 × 3 + 9 - 5

⇒54 + 9 - 5

⇒63 - 5

⇒58

Hence, the correct answer is "Option 3".

Question 150

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

Read the given statement(s) 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 statement(s).

Statements:

All chairs are bats.

No bat is a hat.

Conclusions:

(I) No chair is a hat.

(II) Some hats are bats.

  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: (c)C.

Only conclusion (I) follows

Why this answer is correct

The least possible Venn diagram for the given statements is:

Conclusions:

(I) No chair is a hat - Follows (No bat is a Hat. All chair is bat. So, no chair is a hat is true)

(II) Some hats are bats - Does not follow (As there is no relation between hats and bats). Hence, it is false.

Only conclusion (I) follows

Hence, the correct answer is "Option 3"
