There are three piles of chess pieces, each of which has the same number of pieces, and only black and white pieces. There are as many sunspots in the first pile as there are white stones in the second pile, and the sunspots in the third pile account for (1/4) of all the sunspots. Put these three piles of chess pieces together, what percentage of the total number of white pieces account for the total number of chess pieces?
