Henry Ernest Dudeney/Puzzles and Curious Problems/152 - The Length of a Lease

by : $152$

 * The Length of a Lease
 * A friend's property had a $99$ years' lease.
 * When I asked him how much of this had expired, the reply was as follows:
 * Two-thirds of the time past was equal to four-fifths of the time to come,
 * so I had to work it out for myself.


 * My fault for asking intrusive personal questions.
