Gio, the circus Elephant, is currently three times older than Lee, the circus Lion.   Gio = 3*Lee   Usually, ages are integers so there is a good possibility that the age of Gio is 30 (the only option that is a multiple of 3).   Then age of Lee would be 10. In 10 yrs, Gio would be 40 and Lee would be 20 - so Lee would be half as old as Gio.   Answer (30)
