A bag of balls has two colors of red and yellow. First, 60 balls are taken out, among which there are exactly 56 red balls. After that, there will always be 14 red balls among the 18 balls taken out each time, until the last 18 balls are just taken out. If the total number of red balls in this pile of balls accounts for exactly four-fifths of the total number of balls, how many red balls are there in this bag?
一袋球，有红黄两种颜色，先取出60个球，其中恰好有红球56个．以后，每次取出的18个球中总有14个红球，一直取到最后18个球正好取完．如果这堆球中红球的总个数正好占总球数的五分之四，那么这袋球中红球一共有几个？
