A travel agency plans to launch a "one-day tour of Linzhou Hongqi Canal" for students during the summer vacation. The charging standard is as follows: the number of people is less than M 0, less than m 0. Set group a with x, set group b with y, x> 100. 100。 x+y & gt； 100, but 20800 divided by 85 can't get an integer, and the number of people can't be a non-integer, so x+y must be >; 200, coefficient 75.

90y+85x=20800，75(y+x)=20800。 The settlement is x= 160 and y=80. Team a 160, team b 80.
