Easy Street Challenge Problem:
----------------------------------------------------------------------------
Andy, Brad, Cole, and Doug all live in different houses on Easy Street.
By a curious coincidence, the age of each man is either seven greater or seven less than the number of his house. All of them are over 15 years old and less than 90 years old. their ages are all different.
Andy said that the number of Brad's house was even, and Brad remarked that the number of his house was greater than that of Doug's. "My age," he added proudly, "is a perfect cube."
Cole said that the number of his house was greater by 3 than that of Andy, and that Doug's age was an exact multiple of Andy's age.
Doug, who has an unfortunate habit of complicating things, said that Brad's age was either 27 or an even number other than 64. "Furthermore," he commented, "Cole does not live at number 19."
Unfortunately these remarks were not all true. It was interesting to note that remarks made by those who lived in even-numbered houses were false, and the remarks made by those who lived in odd-numbered houses were true.

What are their ages and the numbers of their houses?
