It depends on what you are rounding it to. 250 is nearer, so it is more likely, like rounding to the nearest 50.
To the nearest ten, 260
It is 250 rounded to the nearest 100 is 300
300
Since 3 (the digit were rounding) is less than 5, the number in which we would round up, 239 would round down to 200
It is then 300 rounded to the nearest hundred because 50 rounds up to 100
