**Reiny**, Sunday, March 21, 2010 at 1:06pmTo be divisible by both 11 and 5, the number must be a multiple of 55

those are: 55, 110, 165, 220, 275, ..

ahh, 275 has its digits add up to 14

For questions in the area of "pure" math such as this question, for me the method of obtaining the answer was more important than the answer itself.
