Truth and Lies
In a city, there are male and female citizens. The male always tells the truth and the female always lie (No discrimination). They are all masked so we do not know which ones are which gender. We asked every person in the city, and their answers are of follows: 1st person: There are no males in this city. 2nd person: There is 1 male in this city. 3rd person: There are 2 males in this city. And so on, until every person on this island is done questioning. If there is x people in the city, how many males are in the city? (Sorry if my grammar is bad)

There is only one male on the island and it is the second person because any other people being male; therefore telling the truth, will make everything contradictory.
