A math problem of self-enrollment
From the meaning of the question, we know that everyone did 1000. Assuming that there are many excellent people, the most excellent people can only be166 (1000/6 ≈166.67). There were 333 people who took the exam, so 167 people failed (300- 166). 166 so the number of people who failed is more than the number who passed, contrary to the assumption.
