Explanation:

For minimum, teams with minimum score would be transferred from A to B
So, total score transferred = 15 * 5 = 75
B (Minimum Average) = (25 x 25 + 75) /30 = 23.33
For maximum, teams with maximum score would be transferred from A to B
So, total score transferred = 25 * 5 = 125
B (Maximum Average) = (25 x 25 + 125) /30 = 25
