Study the following table to answer these questions.
Percentage of marks obtained by 7 students in 6 subjects (maximum marks for each subject is shown in brackets)
Approximately what is the overall percentage of marks obtained by the T in all the subjects ?
Total score by T in all the subjects = .67 * 75 + .74 * 60 + .74 * 80 + .84 *50 + .85 *40 + .82 * 40 = 262.65
Total score possible = sum of maximum scores in all the subjects = 75 + 60 + 80 + 50 + 40 + 40 = 345
Overall percentage = $$ \frac{262.65}{345}*100$$ = 76.13%
