Question

The average marks of 30 students in a class were 52. The top 6 students had an average of 31. What were the average marks of rest of students?

Answer 1

Answer:

57.25

Explanation:

total marks of 30 students = 52*30 = 1560

total marks of 6 = 6*31 = 186

remaining students = 30-6 = 24

therefore, 1560-186 = 1374 marks

average = 1374/24 = 57.25
