There are 25 horses and only five tracks in a race.
How do you find the second coming horse of all the 25
horses, provided there is no stop clock? (obviously, a
horse cannot participate more than once in a race).

Answer = 8 races
Step1(25 horses)
5 races = race all 25 horses in sets of 5.Get 1,2 from each
race so eliminate 15 horses and get 10.
Step2(10 horses left)
2 races = similarly race 10 horses in sets of 5 and get 4,
eliminate 6.
Step3(4 horses left)
1 race = to get the 1st and 2nd.
