To maximize the toppers score, we must minimize the scores of everyone else. So, let the scores of other 20 students be 40 marks each. So, total marks obtained by 20 students = 40 x 20 = 800 Remaining marks = 1564 - 800 = 764 So, score of toppers = 764 ÷ 3 = 254 marks + 2 additional mark This additional mark could be obtained by any other student.
