The Island

"I am a castaway on a deserted island, but I am not alone. There are three monkeys, two cats, and a coconut tree on the island with me. One day, I decided to divide the coconuts among the monkeys equally. After I gave each monkey one coconut, there was still one coconut left. So, I gave that coconut to the cats. The next day, I repeated the same process, dividing the remaining coconuts equally among the monkeys, and again one coconut was left over, which I gave to the cats. This went on for several days until there were no coconuts left. How many coconuts were there in the beginning?"

The answer to this riddle is that there were a total of 7 coconuts on the island in the beginning.
