Getting The Minimum With SOD (Posted on 2008-12-02) Difficulty: 3 of 5
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 computer-assisted method, although computer program/spreadsheet solutions are welcome.
