Given mean = 20 and 5 distinct positive integers. We can set up the following:
(1). 20 = (a+b+c+d+e)/5
(2). 100 = a+b+c+d+e
5 distinct and we need to find maximum of largest integer. set the 4 others to the smallest possible values
100= 1 + 2 + 3 + 4 + e
100=6 + e
90 = e
90 is the greatest value possible.
(1). 20 = (a+b+c+d+e)/5
(2). 100 = a+b+c+d+e
5 distinct and we need to find maximum of largest integer. set the 4 others to the smallest possible values
100= 1 + 2 + 3 + 4 + e
