To maximize the toppers score, we must minimize the scores of everyone else. So, let the scores of other 19 students be 40 marks each. So, total marks obtained by 19 students = 40 x 19 = 760 Remaining marks = 1496 - 760 = 736 So, score of toppers = 736 ÷ 3 = 245 marks + 1 additional mark This additional mark could be obtained by any other student.
