You're a soldier in the dictator's army. The dictator is very impressed with your incredible abilities. He asks you this question:
There are 42 cars in this parking lot over there. How do you transport them to next town?
You're confused by this question, thinking it may be a trick question. He did not specify how to transport them. You cannot find a useful answer, so you finally decide to go with a joke, hoping it will not upset him:
Well, I cannot transport all of them at once, of course. So I just transport 2 times 11 and 2 times 10!
You're not sure how that made any sense, but surprisingly, instead of having you shot, he says:
No, no. You would transport 4 times 2.
Further confused, you ask how 4 times 2 is 42, but he brushes off that question and just confirms that, yes, that's how you would do it. He also confirms that it was not a pun.
How is 4 x 2 a solution? I must add that I do not know the answer, and I do not even know what kind of puzzle it is, so I'm grateful for any possible explanations.
