Getting The Minimum With SOD (Posted on 20081202) 

Determine the minimum value of a positive decimal integer m such that:
SOD(m) = 100, and: SOD(2m) = 110
where, SOD(x) denotes the sum of the digits of x.
Note: Try to derive a non computerassisted method, although computer program/spreadsheet solutions are welcome.
