Choose a number greater than 1029 whose thousandth digit is 4 less than its units digit.
Choose a number greater than 1029 whose thousandth digit is 4 less than its units digit.
To solve this problem, we will evaluate each choice to find the number where the thousandth digit is 4 less than its units digit, and the entire number is greater than 1029.
Choice 1:
Thousandth digit is 1, unit digit is 7. The difference is , which does not satisfy the condition (needs to be 4).
Choice 2:
This does not meet the requirement of being greater than 1029.
Choice 3:
Thousandth digit is 1, unit digit is 5. The difference is , which meets the condition. However, is not greater than .
Choice 4:
Thousandth digit is 1, unit digit is 5. The difference is , and the number is greater than . This satisfies all conditions.
Therefore, among the given options, the correctly chosen number is .
