The pie charts has the marks scored by a student in two exams. The student was to be awarded 15% of the total marks in semester 2 as bonus marks for he had represented the school in national level football competition. He had lost 20 marks in semester 1 as he had submitted his assignments after the due date. What will be this student's net average of both the semesters combined? The student had scored 80 marks in science in semester 1 and 100 marks in arts in semester 2. Correct Answer 76

Calculation:

Percentage marks scored in Arts in semester 2 = 25%

Total marks scored in semester 2 = 100 × 100/25 = 400

Total marks scored in semester 2 with bonus = 400 + 400 × 15/100 = 460

Percentage marks scored in Science in semester 1 = 25%

Total marks scored in semester 1 = 80 × 100/25 = 320

Total marks scored in semester 1 with loss = 320 - 20 = 300

∴ Net average marks = (460 + 300)/10 = 76
