Question 781

RRB Group D 2025• General Intelligence & Reasoning

This question is based on the five, three-digit numbers given below.

(Left) 756 325 685 458 359 (Right)

(Example: 697 – First digit = 6, second digit = 9 and third digit = 7)

(

NOTE:

All operations to be done from left to right.)

What will be the resultant if the third digit of the highest number is added to the third digit of the lowest number?

  1. AOption (a)

    12

  2. BOption (b)

    13

  3. COption (c)

View answer & explanation

Correct answer

Answer: (c)C.

11

Why this answer is correct

The logic followed here is:

Given numbers: 756, 325, 685, 458, 359

Now, Arranging in descending order: 756, 685, 458, 359, 325

Highest number = 756

→ Third digit = 6

Lowest number = 325

→ Third digit = 5

Result = 6 + 5 = 11

Hence, the correct answer is Option 3.

Question 783

RRB Group D 2025• General Intelligence & Reasoning

All 38 students in a class are standing in a row, facing north. Ayush is 16th from the right end while Meena is 21st from the left end. How many people stand between Ayush and Meena?

  1. AOption (a)

    1

  2. BOption (b)

  3. COption (c)

    2

  4. DOption (d)

    0

View answer & explanation

Correct answer

Answer: (a)A.

1

Why this answer is correct

Given: Meena is 21st from the left and Ayush is 16th from the right.

Convert Ayush’s position from right to left:

Ayush’s position from left = (38 − 16) + 1 = 23rd

Now positions are:

Meena = 21st from left

Ayush = 23rd from left

Number of persons between them = (23 − 21) − 1 = 1

So, there is 1 person between Meena and Ayush.

Hence, the odd one out is Option 1.

Question 784

RRB Group D 2025• General Intelligence & Reasoning

Ridam starts from Point A and drives 45 km towards East. He then takes a right turn, drives 48 km, turns right and drives 51 km. He then takes a right turn and drives 63 km. He takes a final right turn, drives 6 km and stops at Point P. How far (shortest distance) and towards which direction should he drive in order to reach Point A again? (All turns are 90-degree turns only, unless specified.)

  1. AOption (a)

    14 km to the South

  2. BOption (b)

    16 km to the north

  3. COption (c)

    17 km to the north

  4. DOption (d)

    15 km to the South

View answer & explanation

Correct answer

Answer: (d)D.

Why this answer is correct

Given:

Ridam starts from A and drives 45 km East.

He turns right → 48 km South.

He turns right → 51 km West.

He turns right → 63 km North.

He takes a final right turn → 6 km East and reaches P.

So, To reach A from P → move 15 km South.

Hence, the correct answer is Option 4.

Question 793

RRB Group D 2025• General Intelligence & Reasoning

In a certain code language, 'TMCB' is coded as '76' and 'GKIR' is coded as '90'. What is the code for 'VAPD' in that language?

    86

  4. DOption (d)

    91

View answer & explanation

Correct answer

Answer: (c)C.

86

Why this answer is correct

The logic followed here is:

Logic: Add the positional values of all the letters in the word and then multiply the total by 2.

For, TMCB → 76

⇒ T = 20, M = 13, C = 3, B = 2

⇒ 20 + 13 + 3 + 2 = 38

⇒ 38 × 2 = 76

For, GKIR → 90

⇒ G = 7, K = 11, I = 9, R = 18

⇒ 7 + 11 + 9 + 18 = 45

⇒ 45 × 2 = 90

Now, applying the same pattern to VAPD:

⇒ V = 22, A = 1, P = 16, D = 4

⇒ 22 + 1 + 16 + 4 = 43

⇒ 43 × 2 = 86

Hence, the correct answer is Option 3.
