Question

in an election about 500,000 people voted in all what could be the exact number of people who voted in the election

Answer 1

The question is, what kind of numbers could be rounded up to 500 000?

Depending on how we round, if we round to 1 000, then:

from 499 500 till 500 499

if we round to the nearest 10 000 then: (I find this most probable)

495 000 to 504 999

if we round up to the nearest 100 000:

450 000 to 549 999
