Well when rounding to the nearest tens place 5 is right in the middle so if we wanted to round it we could go up or down equally. We chose to go up because that was just the convention we chose, no other reason than that. They might have had their reasons why they liked that way better but mathmatically it was just what they decided to go with. Rounding is a man made concept so this was one of the rules we all agreed upon when agreeing on how we will round numbers.
