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:

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: Correct Answer 80

Given:

Subjects

Angle

Maths

80°

Physics

70°

Chemistry

45°

Biology

55°

English

60°

Physical Education

50°

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.
