Answer

Explanation:

To find the greatest four-digit number using any one digit twice, we need to understand the place value of each digit in a four-digit number.

A four-digit number has the following place values:

- Thousands place (from left to right): 1000
- Hundreds place: 100
- Tens place: 10
- Ones place: 1

In order to create the greatest four-digit number, we need to maximize the value of the thousands place. Since we are given the digits 0, 4, and 9, we need to choose the digit that has the highest value to put in the thousands place.

Options:

a) 9404
b) 9440
c) 9940
d) 9400

Explanation of Options:

a) 9404:
- The digit 9 is in the thousands place, which is the highest value we can choose for this place.
- The digit 4 is in the hundreds place, which is the second-highest value we can choose for this place.
- The digit 0 is in the tens and ones places, which are the lowest values we can choose for these places.
- So, the value of this four-digit number is 9404.

b) 9440:
- The digit 9 is in the thousands place, which is the highest value we can choose for this place.
- The digit 4 is in the hundreds and tens places, which are the second-highest values we can choose for these places.
- The digit 0 is in the ones place, which is the lowest value we can choose for this place.
- So, the value of this four-digit number is 9440.

c) 9940:
- The digit 9 is in the thousands place, which is the highest value we can choose for this place.
- The digit 9 is also in the hundreds place, which is the second-highest value we can choose for this place.
- The digit 4 is in the tens place, which is the lowest value we can choose for this place.
- The digit 0 is in the ones place, which is the lowest value we can choose for this place.
- So, the value of this four-digit number is 9940.

d) 9400:
- The digit 9 is in the thousands place, which is the highest value we can choose for this place.
- The digit 4 is in the hundreds place, which is the second-highest value we can choose for this place.
- The digit 0 is in the tens and ones places, which are the lowest values we can choose for these places.
- So, the value of this four-digit number is 9400.

Conclusion:

Out of the given options, the greatest four-digit number that can be formed using any one digit twice is 9940.
