Answer:
93
Step-by-step explanation:
Average of 40 students marks is 86. I.E. Total marks of all 40 students = 40*86 = 3440
Average of 35 students marks is 85, I.E Total marks of 35 students, removing top 5 with highest marks, 35*85 = 2975
Hence the difference in total of 40 & 35 students marks is Point1-Point2
3440–2975 = 465.
Hence average of top 5 students is 465/5 = 93
