Answer 2

Answer: Arranging the numbers in ascending order;

36 , 40 , 48 , 63 , 78 , 80 , 85 , 92 , 96 , 98

The highest number is 98 and the lowest number is 36.

Mean = $\frac{SUM OF THE NUMBERS}{NUMBER OF NUMBERS}$

=  $\frac{36 + 40 + 48 + 63 + 78 + 80 + 85 + 92 + 96 + 98}{10}$

= $\frac{716}{10}$

=71.6

This is what I understood as per the question you  wrote.

Sorry if it is not what you wanted.
