 John took a test that was divided into three sections with varying numbers of questions and different success rates. In the first section, there were 50 questions, and John answered 85% of the questions correctly. The second section had 60 questions, and John was able to answer 70% of these correctly. The final section had 40 questions, and John managed to answer 95% of them correctly. If there is a negative marking scheme in which 0.25 marks are deducted for every wrong answer, how many total marks will John obtain? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
