During each passing minute, the number of leaves that fell was equal to the total on the ground plus one. If the pattern continued, how many leaves fell during the 12th minute? During the 24th minute? How many leaves would fall during the nth minute.

Chocolate Problem: Last vacation, my cousin came over to stay at my home. We made the most of her stay at my place... and I even earned a few chocolates. Everyday we would play a game of chess. Whoever lost the game owed a chocolate to the other. After the last game we played (that was the day she was to leave), we counted the number of games each of us had won and lost. Wow! I had won more than her. So, she handed me 20 chocolates... though she herself was the winner in 7 games. How many days did my cousin spend at my place?
