Title: Swan Lakes.
Post by rloginunix on Feb 20th, 2014, 11:55am
Swan Lakes.

A flock of swans is approaching a group of lakes. Every time the swans are flying over a lake one half of them plus half-a-swan land while the remaining swans continue on to the next lake. In that fashion all the swans land on 7 lakes.

How many swans were in the flock?

(This is the second problem in a series of three related ones. The first problem is "The Devil and the Loiterer". The third and the last one is "The Devil, Swans, Two Eggs and a 100-story building").

riddler358 is correct.

And now on to the third and final problem that will make it clear why I started this in the first place. Please go to "The Devil, Swans, 2 Eggs and a 100-story Building".
