Question
The average score obtained by 22 students in a class
test is 68 marks. The top place was shared by 3 people who got the same score. If the lowest score was 40 marks, then which of the following could be the highest score obtained by toppers? (Marks scored by each student is a whole number)Solution
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.
