    To 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.
