Question

Use the digits 1 through 7 to create the seven digit number that can be rounded to 6300000

Answer 1

The answer for this question is 6275421 or 6257421
When you round up to 6300000 it should be clear that the first two number would be 62. For the next number, you can use 5 or 7 which will be round up. The rest of the number after that is not important.
