The little white rabbit went up the mountain to pick a lot of mushrooms. It divided these mushrooms into 4 piles on average, gave 3 piles to its good friends, and kept one pile for himself. Later, it divided the leftover pile into 3 piles on average, gave two piles to other little white rabbits, and ate one pile for himself, and the pile he ate contained 7 mushrooms. Do you know how many mushrooms the little white rabbit picked?
