Study the data table and answer the questions that follow
The following table shows the maximum marks of each subject inside the bracket and percentage of marks obtained by seven students in six different subjects in the exam.
What are the average percentage of marks (%) obtained by all the seven students in Physics?
- A.
~82.42
- B.
~74.28
- C.
~86.24
- D.
~95.14
Show answer & explanation
Correct answer: B
Use the Physics column only. The seven Physics percentages are 90, 80, 70, 80, 85, 65 and 50. Their total is 90 + 80 + 70 + 80 + 85 + 65 + 50 = 520. Average percentage = 520/7 = 74.2857..., which is approximately 74.28%. Therefore, the correct answer is ~74.28.
