This problem is making the rounds on Facebook and Twitter with thousands of people arguing about the correct answer. How smart are you? A guy walks into a store and steals a $100 bill from the register without the owner’s knowledge. He then buys $70 worth of goods using the $100 bill and the owner gives $30 in change. How much money did the owner lose? $30, $70, $100, $130, $170, or $200?
