Question 731

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

In a row of 38 people facing the north, Keerthi is 13th from the right end. If Tanvi sits 7th to the left of Keerthi, what is Tanvi’s position from the left end of the row?

  1. AOption (a)

    17th

  2. BOption (b)

    19th

  3. COption (c)

    20th

  4. DOption (d)

    18th

View answer & explanation

Correct answer

Answer: (b)B.

19th

Why this answer is correct

The logic followed here is:

  • Total number of people in the row = 38
  • Position of Keerthi from the right end = 13th

Position of Tanvi from the right end = Position of Keerthi from the right end + 7

= 13 + 7

= 20

Position of Tanvi from the left end = Total number of people − Position of Tanvi from the right end + 1

= 38 − 20 + 1

= 19

So, Tanvi is 19th from the left end of the row.

Hence, the correct answer is 'Option 2'.

Question 732

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

135 146 168 201 245 ?

  1. AOption (a)

    280

  2. BOption (b)

    310

  3. COption (c)

    300

  4. DOption (d)

    290

View answer & explanation

Correct answer

Answer: (c)C.

300

Why this answer is correct

The logic followed here is:

  • 135 + 11 = 146
  • 146 + 22 = 168
  • 168 + 33 = 201
  • 201 + 44 = 245
  • 245 + 55 = 300

Hence, the correct answer is 'Option 3';

Question 734

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

Each of the digits in the number 7632198 is arranged in ascending order from left to right. The position(s) of how many digits will remain unchanged as compared to that in the original number?

  1. AOption (a)

    NONE

  2. BOption (b)

    ONE

  3. COption (c)

    THREE

  4. DOption (d)

    TWO

View answer & explanation

Correct answer

Answer: (b)B.

ONE

Why this answer is correct

The original number provided is: 7632198

Original Number7632198
Ascending Order1236789

By comparing the two sequences, we can see that:

Therefore, only one digit (the digit 3) remains in the same position as in the original number.

Hence, the correct answer is "Option 2 "
