Question 551641
AVG = SUM/# where # is the total number of numbers. <P>
In this case the lowest possible average occurs when 15 give the least possible amount, 100, and the remaining 10 people give 0.<P>
The sum 100+100+100...15 100's = 100*15=1500
The total number of people is 25
AVG = x = 1500/25 = 60
