# Donald Lies

Donald and Kim work at a Coca Cola warehouse in Los Angeles.

Today Donald and Kim worked together unloading 3 full trailers. They unloaded without anyone else assisting them.

A fully loaded trailer contains 56 skids. While they were on their coffee break, co-worker Michael accidentally loaded 14 skids on one of the trailers thinking it was an outbound trailer.

Later on after they finished unloading, Donald bragged to his boss Vladimir that he unloaded 27 more skids than Kim. That was impressive, so Vladimir asked Donald if he was truly sure he unloaded that many more skids than Kim. "I'm completely sure," replied Donald. "I lined up all my skids here, Kim unloaded all his over there, so you can count them if you want. It's cuz slacker Kim started his shift half an hour late and took a longer break than he should."

Vladimir counted, confirming that Donald's line had 27 more skids than Kim's. That afternoon, Vladimir wrote up Donald for lying on the job. How does Vladimir know that Donald lied (beyond Donald having a habit of doing it)?

### Hint

The skids they unloaded must total 182.### Answer

With an even number of skids (182) and two people unloading them, the difference between how many each worker unloads must be a multiple of 2. Each additional skid one unloads is one less skid the other unloads. For example, with 182 total skids, if one unloads 92 then the other unloads 90. Or if one unloads 93, then the other unloads 89. The difference must always be a multiple of 2. So if Donald's line has 27 more skids than Kim's line, he must have cheated taking skid(s) from elsewhere to make it appear as though he unloaded them.Hide Hint Show Hint Hide Answer Show Answer
