Question 271715
<font face="Garamond" size="+2">


He gave the last guard everything, which was half of what he had plus 2.  So 2 had to be the other half of what he had -- hence he had 4 when he met the last guard.  The guard before then got 2 more than half, so half must have been 6, and he had 12 after his encounter with the first guard.  12 plus 2 is 14, times 2 is 28 which is the number he had at the start.
