Hi @josegonzalito, thanks for these puzzles I really like solving them. I have a question and a suggestion, if thats ok.

Question : Sheep have 2 hooves on each leg, but together its called a cloven hoof, so which one are you referring to in Problem 2. Should we count 1 hoof per leg or 2?

Suggestion : It would be good to give separate higher prize for the first person giving all correct answers and distributing the remaining prize among others. Otherwise others can blindly copy the answers and the person who put the effort solving it first will not get any benefit. I have the answers for Problem 1, but once I post it anyone can copy. :-)
