Answer 1

Answer:

option (b) 6038 is the correct answer

Answer 2

Given:

A four-digit number.

The digit at thousands place is twice the digit at tens place.

To find:

The four-digit number.

Solution:

We have a four-digit number. Let the ones place be $o$, tens place be $t$, hundreds place be $h$ and thousands place be $u$.

But according to the given information,

thousands place = 2 × tens place

$u=2t$

From the given options, consider the first option 2023.

Here, 3 is in the ones place, 2 is in the tens place, 0 is in the hundreds place, and 2 is in the thousands place.

But here, the 2 in the thousands place is not twice of the 2 in the tens place. So, this is not the right option.

Consider the next option, 6038.

Here, 8 is in the ones place, 3 is in the tens place, 0 is in the hundreds place, 6 is in the thousands place.

Here, 6 which is in the thousands place is twice the digit 3, which is in the tens place. Hence, option (b) is the correct answer.

6038 is the four-digit number whose thousands place is twice the digit at tens place. Option (b) is the correct answer.
