I am an odd 5-digit whole number made up of different digits.
The digit in the ones place is 9.
so, we know this: xxxx9

My ten+thousands digit is 4+less than the ones digit: => ten+thousands digit is 9-4=5
now, we know this: 5xxx9

My thousands digit is 4 times the hundreds digit:

My hundreds digit is twice the ten digit.
if hundreds digit is twice the ten and thousands digit is 4 times the hundreds, then thousands digit is 8 times the tens
8 times the tens could be only possible if tens digit is 1
if tens digit is 1, then the hundreds digit is 2%2A1=2
if the hundreds digit is 2, then thousands digit is 4%2A2=8
so, I am 58219
