Brain Teasers
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

Awesome teaser. Were Donald, Kim, and Vladimir named after Trump, Jong-un, and Putin?
Donald having a habit of lying, Vladimir being his boss...naming wasn't just a coincidence
What if Robert was assigned to investigate the situation and got Michael to cooperate. He could learn that Michael was more confused than people realized. Not only did he load a skid from the warehouse onto the truck, but he also loaded 13 of the skids Kim had just unloaded. This decreased the number of skids in Kim's row and increased the total number of skids by one, totaling 169, not 182. Kim wasted a bit of time after lunch looking for his missing skids, during which time Donald unloaded 14 more, putting him 27 skids ahead of Kim.
KIm unloaded 84 skids, and had 71 in his row. Donald unloaded 98 skids.
Robert vindicated Donald, somewhat. Donald unoaded more, but exaggerated the amount and didn't give the reason why.

Then Michael tells Robert that Donald told him to put the extra skids on, wanted to send them to a woman he used to go fishing with.
