Question

What is the percent of discount on an item that has a sale price of $675.05 and regular price of $750.50? Round to the nearest whole number percent.

Answer 1

oh :) heh... that is COMPLETELY original... never seen a problem like this before :)

Answer 2

LOL

Answer 3

% discount = (original price - new price) / original price

Answer 4

one more interesting (maybe) oddity of percent increase and decrease... think about how a value will change if you successively increase it by 10% then decrease the result by 10% then increase that result by 10% and then decrease that result by 10%.

It is tempting to say that you get back the original value... but it isn't correct using these increase and discount definitions. :)

Answer 5

yup ):D

Answer 6

Something to think about as a stock price goes up by a few percent during a day, then down by a few percent... you have to watch the real values over time, because although you could, in theory, try to add up the individual percentage increases and decreases, it would be a serious pain :)
