After a logic test, Lan Lan, Jingjing, and Lingling discussed the test results together  Lanlan said: If I can get 100 points, Jingjing can also get 100 points  Jingjing said: I see Lanlan can get 100 points, I can't get 100 points  Lingling said: If I can get 100 points, Jingjing won't get 100 points
In fact, after the test results came out, it proved that only one of the three of them told the truth
Lingling is telling the truth, Jingjing did not score 100 points.
