Given , number
27487
So, the thousands digit of
27487 is
7.
[If thousands digit is less thgan
5 , replace each thousand, hundreds, tens and one's digits by
0 and keep the other digits as they are . Also , if in the given number, thousands digit is
5 or more than
5 , increase ten-thousand digit by
1 and replace each other digit on its right by
0.
∵ 7 is more than
5.
So, to round off the given number to the nearest ten-thousand ,we increase
2 (ten-thousand digit) by
1 and replace
7 (thousand digit ),
4 (hundreds digit),
8 (tens digit ) and
7 (one's digit by

∴ 27487 is

Hence, round off of
27487 to nearest ten- thousand is
