You can only use the digits 09. I need an odd number that is a multiple of five with no repeated digits. Half the digits are odd and the other half is even. The largest digit in the number is in the tens place (but it is not the largest digit). The digit in the hundreds place is half the digit in the tens place. The sum of the digits is greater than 20.

(I think 7485 will also do it: an explanation of the logic is supplied in response to Amy's posting of this question.)
