In Levikland, there are coins worth 1, 2, 5, 10, 20, 50 and 100 perplexii. A has twice as much money as B, who has twice as much as C, who has twice as much as D. How can this be, if everybody has two coins?
A has a 20 coin & a 100 coin = 120 perplexii
B has a 10 coin & a 50 coin = 60 perplexii
C has a 10 coin & a 20 coin = 30 perplexii
D has a 5 coin & a 10 coin = 15 perplexii
Solution
