Question 1361

RRB Group D 2025• General Intelligence & Reasoning

LMQR is related to VWAB in a certain way based on the English alphabetical order. In the same way, IJNO is related to STXY. To which of the given options is HIMN related, following the same logic?

  1. AOption (a)

    RTVE

  2. BOption (b)

    RSVX

  3. COption (c)

    RSWX

  4. DOption (d)

    RRVX

View answer & explanation

Correct answer

Answer: (c)C.

RSWX

Why this answer is correct

Logic followed here is:

Each letter in the first group is shifted forward by 10 positions in the English alphabetical series to obtain the corresponding letter of the second group.

For LMQR is related to VWAB →

IJNO is related to STXY →

The pattern observed is: Every letter is shifted by +10.

Similarly, let's find the code for HIMN:

 

Therefore, 'HIMN' is related to 'RSWX'.

Hence, the correct answer is "Option 3".

Question 1362

RRB Group D 2025• General Intelligence & Reasoning

If ‘P’ stands for ‘×’, ‘Q’ stands for ‘÷’, ‘R’ stands for ‘-’ and ‘S’ stands for ‘+’, what will come in place of the question mark (?) in the following equation?

3 P 9 R (14 Q 2) P 6 S 80 Q 5 S 4 P 10 = ?

  1. AOption (a)

    41

  2. BOption (b)

    59

  3. COption (c)

    52

  4. DOption (d)

    33

View answer & explanation

Correct answer

Answer: (a)A.

41

Why this answer is correct

The conversion table for letters to operators is as follows:

PQRS
×÷-+

 

Applying the logic to the given equation:

3 P 9 R (14 Q 2) P 6 S 80 Q 5 S 4 P 10 = ?

Substitute the symbols into the equation:

3 × 9 - (14 ÷ 2) × 6 + 80 ÷ 5 + 4 × 10

⇒ 27 - 7 × 6 + 16 + 40 = ?

⇒ 27 - 42 + 56 = ?

⇒ 83 - 42 = ?

⇒ 41 = ?

Therefore, the value that will come in place of the question mark is 41.

Hence, the correct answer is "Option 1".

Question 1370

RRB Group D 2025• General Intelligence & Reasoning

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 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)

    (3,4, 13)

View answer & explanation

Correct answer

Answer: (d)D.

(3,4, 13)

Why this answer is correct

Logic followed here is: The third number is obtained by multiplying the first and second numbers and then adding 1 to the product.

For

(5, 3, 16) →

Calculation = (5 × 3) + 1 = 15 + 1 = 16

(7, 2, 15) →

Calculation = (7 × 2) + 1 = 14 + 1 = 15

Similarly, Option 4) (3, 4, 13):

Calculation = (3 × 4) + 1 = 12 + 1 = 13

Therefore, the set that follows the same logic is (3, 4, 13).

Hence, the correct answer is "Option 4".

Question 1373

RRB Group D 2025• General Intelligence & Reasoning

In the following triads, each group of letters is related to the subsequent one following a certain logic. Select from the given options, the one which follows the same logic.

DUAL – ULDA – ADUL

RATE – AERT – TRAE

  1. AOption (a)

    ROAD – ODRA – AROD

  2. BOption (b)

    RENT – RTEN – ENRT

  3. COption (c)

    GROW – ROWG – ORGW

  4. DOption (d)

    VIEW – WVIE – EWIV

View answer & explanation

Correct answer

Answer: (a)A.

ROAD – ODRA – AROD

Why this answer is correct

Logic followed here is: The second and third words in each triad are formed by rearranging the letters of the first word based on specific positional changes.

For DUAL – ULDA – ADUL →

Word 2 (ULDA) = Positions (2, 4, 1, 3) of Word 1.

Word 3 (ADUL) = Positions (3, 1, 2, 4) of Word 1.

 

For RATE – AERT – TRAE →

Word 2 (AERT) = Positions (2, 4, 1, 3) of Word 1.

Word 3 (TRAE) = Positions (3, 1, 2, 4) of Word 1.

 

 

Similarly, Option 1) ROAD – ODRA – AROD:

Word 2 (Positions 2, 4, 1, 3) = O, D, R, A → ODRA

Word 3 (Positions 3, 1, 2, 4) = A, R, O, D → AROD

Therefore, the triad 'ROAD – ODRA – AROD' follows the same logic.

Hence, the correct answer is "Option 1".

Applying the interchange to the entire equation:

Equation becomes: 4 × 2 - 15 ÷ 5 + 8 = ? - 5

Applying BODMAS rule:

⇒ (4 × 2) - (15 ÷ 5) + 8 = ? - 5

⇒ 8 - 3 + 8 = ? - 5

⇒ 16 - 3 = ? - 5

⇒ 13 = ? - 5

⇒ ? = 18

Therefore, the code for '?' is 18.

Hence, the correct answer is "Option 1".

÷+×-
×-÷+

After interchanging the signs, the new equation is: 59 × 11 - 833 ÷ 7 + 24

Solving using BODMAS rule:

⇒ (59 × 11) - (833 ÷ 7) + 24 = ?

⇒ 649 - (833 ÷ 7) + 24 = ?

⇒ 649 - 119 + 24 = ?

⇒ 674 - 119 = ?

⇒ 554 = ?

Therefore, the code for the question mark is 554.

Hence, the correct answer is "Option 4".
