For a bag of peanuts, it takes Xiaohong 10 minutes to eat alone, Xiaolan takes 12 minutes to finish eating alone, and Xiaobai takes 16 minutes to finish eating alone. Now the three of them eat together. Eat less than 20 peanuts (not less than 20 but less than 30), and as a result, the three of them finished the bag of peanuts in 5 minutes, so how many peanuts are there in this bag?
一袋花生，小红单独吃用10分钟吃完，小兰单独吃用12分钟吃完，小白单独吃完用16分钟吃完，现在三人一起吃，由于互相影响使得三人每分钟一共少吃二十多颗(不少于20但不到30颗)，结果三人5分钟就吃完了这袋花生，那么这袋花生一共有多少颗．
