Dosi hopes that teachers from the Chinese, Mathematics, and English groups of primary schools will participate in fun games. The competitions include blowing balloons, eating oranges, and throwing basketballs. The top three in each competition will get 5 points for the first place, 3 points for the second place, and 1 point for the third place (there is no tie in the rankings in the single event). It is known that the number of teachers in the top three in the language group is the least, and the number of teachers in the top three in the mathematics group is twice that of the language group, and the total scores of these two groups are equal and tied for the first place. How many points did the teacher in the English group get?
多思希望小学语文组、数学组、英语组的老师参加趣味游戏比赛，比赛项目有吹气球、吃橘子、投篮球．每项比赛各取前三名，第一名得5分，第二名得3分，第三名得1分(单项赛中名次没有并列情况)．已知语文组进入前三名的老师人数最少，数学组进入前三名的老师人数是语文组的2倍，并且这两个组所得总分相等并列第一．英语组的老师得了多少分？
