    I first read this problem in a book called "EL hombre que calculaba", by
Malba Tahan.  I don't know the english title 8you how this things are), but

    I'll look it up in Amazon and tell you the title.  It has some very
interesting and entertaining math problems.  And, swear to god, you don't
need any software tro work them out, not even a calculator or a slide rule.
