The given pie chart shows the marks obtained in an examination by a student (in degrees). Observe the pie chart and answer the question that follows. If the total marks are 720, then the difference between the total marks obtained in Physics, Maths and Physical education and the total marks in Chemistry, Biology and English out of the total marks is:

Total marks = 720
Calculation:
Marks scored by the student in Maths = 80/360 × 720 = 160
Marks scored by the student in Physics = 70/360 × 720 = 140
Marks scored by the student in Chemistry = 45/360 × 720 = 90
Marks scored by the student in Biology = 55/360 × 720 = 110
Marks scored by the student in English = 60/360 × 720 = 120
Marks scored by the student in Physical Education = 50/360 × 720 = 100
Total marks obtained in Physics, Maths and Physical education = 160 + 140 + 100 = 400
Total marks obtained in Chemistry, Biology and English = 90 + 110 + 120 = 320
Difference = 400 – 320 = 80
∴ The difference between the total marks obtained in Physics, Maths and Physical education and the total marks in Chemistry, Biology and English out of the total marks is 80 marks.
