The smallest that will round up is 650. The smallest that will round down is 701.
To round a number to the nearest 10, you select from the closest multiple of ten that's higher (900) and the closest that is lower (890). Whenever a number has units of 0,1,2,3,4 you round down, and whenever a number has units of 5,6,7,8,9 you round up. In this case, the units are 5, so you round up, meaning that 895 is 900 when rounded to the nearest 10.

When rounding to the nearest hundred, half will round down and half will round up, ie 100 ÷ 2 = 50 will round each way. → any number greater than or equal to 900 and less than 900 + 50 = 950 will round down to 900. ie any number n such than 900 ≤ n < 950 will round down to 900 to the nearest 100. Which means your [whole] number could be any of 900, 901, 902, ..., 949.
