A Few Coins II (Posted on 2005-05-12)

In A few coins, we learned about Levikland, in which the currency is perplexii. The coin values are 1, 2, 5, 10, 20, 50, and 100 perplexii.

How many perplexii can you have and still not be able to make change for a 100 perplexii coin?

143 perplexii. You could have 1 50, 4 20's, 1 5, and 4 2's, but still wouldn't be able to make change for a 100 perplexii coin.
