There are 25 horses. We have to find out the fastest 3 horses. In one race maximum 5 horses can run. How many such races are required in minimum to get the result ?

Possible Solution: Timer allowed? If you got a timer to time each horse, you probable need 5 races. After 5 races you ot time each horse takes to finish and then select top 3. Timer not allowed? May be 7 ? How.. guess..
