20 students took a test worth 100 marks. All these results were positive integers and none of them had the same score. Their teacher ranked them from the highest score (1st) to the lowest score (20th). The top 10 students had an average of 92 marks and the next 10 students had an average of 80 marks. The top 5 students had an average that was 12 marks higher than the average of the next 15 students. Find the lowest possible score of the student in the 20th rank.
