I never saw this until today, but it seems to have been going the rounds for some years and generated a lot of discussion. Googling the first phrase gets over 2 million hits.
A man buys a horse for £60 and sells it for £70. He then repurchases for £80, and sells it for £90.
Has he gained or lost, if so by how much? Or has he broken even?
Sometimes it’s a goat or a pig etc.
9 students and 9 professors attend a dinner at which they sit at a round table. The organisers wish to arrange the seating so that no one is seated between two professors. Is this possible to meet this condition?
Solution: Imagine we have found an arrangement that meets the conditions. Ask every other person to stand up, so 9 people will be standing. Then we cannot have two professors separated by only a single seated person, otherwise that person would be flanked by professors. But this means only 4 of the 9 standing persons can be professors.
However the same reasoning can be applied to the 9 people who are sitting down, so we can only accommodate 8 professors altogether, leaving one professor unaccounted for.
Consequentially no arrangement can exist that meets the given condition.

For several hours there has been almost no wind in my garden, the wind speed is effectively 0 km/h.
I think this must be quite unusual, although the Hairy Ball Theorem tells us that there must always be a point on the earth where the wind isn't blowing at any given moment.

Well, they got battered.
