39.5 + 0.5
=40, not 41
55.5 + 0.5
=56, not 57
Its only possible if you round up 40.1 to 41, which is also bad math. When there are 3 variables properly rounded up, you can only have 3x0.5 added.

What I say is that there is more than three variables. The three variables are already the result of addition if other variables rounded.

39.5 = 40 0.5 = 1 40 + 1 = 41 55.5 = 56 0.5 = 1 56 + 1 = 57 3.5 = 4 Since the original 5 numbers only add up to 95.5, you have a leftover 0.5 to distribute between them. After doing so, you would have what could have been the original results before rounding.
