The answer that rounds 36257 to the nearest multiple of a 1000?

Answer 1

The basic rule rule for rounding off to the relevant number of significant figures is :- If the first figure to be discarded is 5 or more, the previous figure is increased by 1

When rounding to the nearest 1000 (which is the same as to the nearest multiple of 1000) then the first figure to be discarded is the digit representing the hundreds. In this question that digit is "2". As this is less than 5 then the previous figure is notincreased by 1.

36257 is thus rounded to 36000.
