Number of students who obtained more than 69 but less than 140 marks in Maths is approximately how much percent less or more than that of the students who scored either equal or more than 105 marks in Physics?

Number of students who obtained more than 69 but less than 140 marks in Maths = 43 +53 = 96 Number of students who obtained either equal or more than 105 marks in Physics = 44 + 31 = 75 So Required % = (96-75)/75`xx` 100 = 28%
