"In a circle of 33, the next 10 people on my right are all liars" 
In the land of Truthlandia, each person is either a truth teller who always tells the truth, or a liar who always tells lies. All 33 people who gathered for a meal in Truthlandia at a round table, said: "The next 10 people on my right are all liars." How many liars were actually in attendance?

I have looked around quite a lot, but the closest I could find was this. If anybody can answer that would be greatly appreciated. Thanks for any answers!

A truth-teller, by the given statement, forces the nature of the ten people to the right – a block of eleven. However, there cannot be a block of eleven liars, because the leftmost "liar" would actually be telling the truth. Thus there are three equally-spaced truth tellers and 30 liars.
