In the entrance examination of IIMs, there were 200 questions, each of which carried the same marks. A correct answer gets 2 marks and there is 100% negative marking. A total of 70 candidates took the exam and it was later found that the average marks obtained by these 70 candidates was 240. The candidates were not required to attempt all the questions. None of the candidates got more number of incorrect answers than correct answers.
If the topper had a net score of 380 and the sixth ranker had a net score of 370 and the net scores of the top six rankers were distinct, then what would be the average net score of the 64 students who got ranks from the seventh to the last?
