How Old is the Rose-Red City?


after Martin Gardner

Home / Puzzle Playground / Puzzles / Math 'n' Logic /

"A rose-red city half as old as Time.
One billion years ago the city's age
Was just two-fifths of what Time's age will be
A billion years from now. Can you compute
How old the crimson city is today?"

Based on these five lines can you figure out how old is the Rose-Red city?
