Detailed Solution

Given number is

47, 897

.
If the number that is rounded up is followed by 5, 6, 7, 8, or 9, then round the number up. Example: 38 rounded to the nearest ten is 40.
If the number that is rounded up is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.
In number 47897, its hundred digit is 8, which is greater than 5.
So, we increase the digits at thousand place by 1 and replace each one of the digits at hundreds, tens and ones place by

0

to round off the given number to nearest to 1000.

∴

The number becomes

48, 000

Therefore, option (2) is correct.
