There are 900 three-digit numbers, all of which are between 99 and 3,000.
Half of them. Every other number from 0 to 99998 is even. Since there are 90,000 five digit numbers, that means that 45,000 of them are even.
There are 450 even three-digit integers, from 100 to 998. This excludes numbers with leading zeroes (000 to 099).
There are 449999 such numbers.
With a total of 90,000 five digit numbers, we can conclude that there is 45,000 EVEN five digit numbers.
