In an entrance test with 180 questions, there are three sections: Physics (40 questions), Chemistry (70 questions), and Biology (70 questions). A student answered 75% of Physics, 55% of Chemistry, and 45% of Biology questions correctly. If the minimum passing score is 62%, how many more questions did the student need to answer correctly to pass?

1. 9.6
2. 10
