Passage Summary: The sales manager says the company is doing great because total sales are up. The accountant points out that every single restaurant they already had is actually selling less food than it used to.

Reasoning: The total number of meals sold by the company increased overall, but every individual restaurant that was open in both the current and previous year saw a decrease in sales.

Analysis: This is a numerical puzzle that requires a logical deduction. If the 'old' restaurants are all selling less, but the 'total' sales for the company are higher, there is only one mathematical possibility: the company must have added new sources of revenue. Specifically, they must have opened new restaurants that didn't exist the year before. These new locations would have to sell enough meals to cover the losses at the old locations and still increase the total. Look for an answer that confirms the opening of new restaurant locations.
