Shobha’s mathematics test had 75 problems i.e.10 arithmetic, 30 algebra and 35 geometry problems. Although she answered 70% of the arithmetic ,40% of the algebra, and 60% of the geometry problems correctly.  she did not pass the test because she got less than  60% of the problems right. How many more questions she would have to answer correctly to earn 60% of the passing grade
