#### A man bought a farm for \$2,400 and sold it for \$2,700. What percent did he gain?

The answer is 12.5%. Here's how you figure it out: Divide 2700 by 2400, which equals 1.125. Then take 1.125 and multiply it by 100, to get the percentage. That gives you 112.5%. The difference between 100% and 112.5% is 12.5%. There is your answer. (2700*100):2400 = 270000:2400 = 112.5
If you thought eighth grade was hard at the time- what with that whole puberty thing mucking everything up- you might be in for a rude awakening: almost EVERYONE has trouble with this quiz. Is it possible none of us was really paying attention in class? Or maybe we just don't get enough chances to practice our knowledge of basic bio, math, or history. Whatever the reason, we're warning you know: this test gets very, very tough. Good luck, scholar.
