A tourist is enjoying an afternoon refreshment in a local eatery when the manager says to him Do you see those three men over there? One is Mr. X who always tells the truth. Another is Mr. Y who always lies. The third is Mr. Z who sometimes tells the truth and sometimes lies. You may ask them three Yes/No questions always indicating which man should answer. After asking these three questions, if you correctly identify Mr. X, Mr. Y and Mr. Z then your bill is on them. What Yes/No questions should the tourist ask?

Here's a logic question. Can anyone provide an answer? Puzzle:You have 25 horses, and you want to pick the fastest 3 horses out of those 25. In each race, only 5 horses can run at the same time because there are only 5 tracks. What is the minimum number of races required to find the 3 fastest horses without using a stopwatch?

first let the 5 sets each set having 5 horses to run.find the winning horse in all the 5 sets,then let the 5 won horses to run to find the fastest 3 horses.so the minimum no. of races is 6.
