AI explanation

To find the average of the scores, apply the arithmetic mean formula by dividing the sum of the marks by the number of subjects. The sum of the scores is 85 plus 86 plus 98 plus 82, which equals 351. Because there are 4 subjects, divide the total sum by 4. This calculation gives 351 divided by 4, resulting in an average of 87.75.
