Each of George’s and Martha’s five great-grandchildren celebrates a single-digit birthday today. “If you add their ages and reverse the digits of the total,” Martha said, “you get a two-figure number divisible by Andrew’s age and by none of the others’.” “That pattern continues,” George added. “Eliminate Andrew and the same is true of the other four, giving a number divisible by Brian’s age and none of the other three. If you eliminate Brian, the same is true for the other three with Colin’s age. Eliminating Colin, this works for the other two with David’s age.”

How old are the five children?
