Question
The average score of 24 students in a class is 78. If
the top 4 scores are removed, the new average score of the remaining students drops by 2 points, what is the average score of the top 4 scorer students?Solution
ATQ, Total score of 24 students = 24 ×78 = 1872 Original average = 78, New average = 76, Total score of the remaining 20 students = 20×76 = 1520 Score of top 4 scorer students = 1872-1520 = 352 Required average = 352/4 = 88
