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".

  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'.

  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.

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

18 − 3 ÷ 9 + 15 × 3 = ?

  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".

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"

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'.

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.
