Assuming you are dealing with whole numbers only:
Half of the numbers round up and half round down.
Half of ten thousand is five thousand.
Therefore 400000 ± 5000 round to 400000 to the nearest 10000; except that numbers exactly half way round up, so the maximum is one less than this.
→ smallest to round [up] to 400000 is 400000 - 5000 = 395000
→ largest to round [down] to 400000 is 400000 + 5000 - 1 = 404999
They are 395000 and 405000.
To solve this, you have to consider what the largest and smallest numbers could be to cause the ten thousand's place to round to a 0.404,444 is the largest, because if you round to the ten thousand's place, it will still be 400,000. If any of the 4s becomes a 5, it will round up to 410,000.394,445 is the smallest, because if you round to the ten thousand's place, it will round up to 400,000

It is 400000.
It is 400000.
The answer is 400000.
It is 400000.
