S={1,2,3,………..10} in this set what is the lower and upper bound

• Yvonne Vella says:

I cannot understand why the upper bound goes above the bound. Let me explain. Let us suppose that we have to find the upper and lower bounds of 250 correct to the nearest ten. I agree that the lower bound is 245 but I cannot understand why the upper bound should be 255. According to normal practice if we are asked to express 255 to the nearest ten we would give it as 260 and not 250. Do you think you can enlighten me on this point?

I understand the first part where you explain about the upper bound and the lower bound, but when I see the working, I kind of get confused.
