My favorite numbers VII (Posted on 2011-04-06) Difficulty: 3 of 5
Each of A, B, C and D is a positive integer, with A > B, such that: A+B = C - 11*D.

Determine (with proof) the quadruplet (A, B, C, D) that generates the minimum value of A+B+C+D. What quadruplet generates the next smallest value of A+B+C+D?
