Gustavo has a certain amount of coins of 1, 10, 25 and 50 cents, with at least one of each value. It is impossible to combine them in order to get exactly R$ 1,00. What is the largest possible total value for their coins?
Notes
Combine to get R$ 1 is if you have 2 coins of 50 cents you have R$ 1. But if you have 2 coins of 10 cents you have only 20 cents, you can't combine these coins to get RS 1. R$ is Real sign, the Brazil currency. 100 cents is 1 Real.

You can only have 1 50, therefore only 1 25, 5 tens would be too many, 4 tens wouldn't, 5 ones would mean (50+25+10+10+(1x5)) so only 4 ones. These add to make 1.19
