What is the largest number that can be rounded off to 5000?

Answer 1

That depends what you're rounding to:

To the nearest 5, 5002

To the nearest 10, 5004

To the nearest 100, 5049

To the nearest 1000, 5499

To the nearest 2500, 6249

To the nearest 5000, 7499

Rounding to anything above 5000 would not provide a result that could be 5000, so the largest whole number I can round to 5000 would be 7499.
