Solution: List the following equations:
Xiaoling+Xiaojun = 195 (1)
Xiaoling+Xiao Fang = 198 (2)
Xiaojun+Xiao Fang = 193 (3)
Add the left and right terms of the three equations respectively to obtain:
2× (Xiaoling+Xiaojun+Xiao Fang) =586
That is Xiaoling+Xiaojun+Xiao Fang =293 (4).
Derived from formula (4) -( 1)
Xiao Fang =293- 195=98.
Derived from formulas (4) -(2)
Xiaojun =293- 198=95
Derived from formulas (4) -(3)
Xiaoling =293- 193= 100
It can be seen that Xiao Fang got 98 points, Xiao Jun got 95 points and Xiao Ling got 100 points.
