One of the most famous puzzles in the math world is "How Old is Ann?" Here's another variation. Ann is now exactly two-fifths of her older sister's age, and two years from now she will be one-half of her older sister's age. Conversely, two years ago, Anne was one-fourth the age of her older sister's age at that time. How old is Ann now? (She's a fairly young child, by the way.)
