Technology analyst interview questions shared by candidates
Out of 25 horses, pick the fastest 3 horses. In each race, only 5 horses can run at the same time. What is the minimum number of races required?
You need 7; first 5 races to determine ranking among groups of 5, then you can race the winners from each 5 group and that will give you the fastest one. Then to get 2nd and 3rd horse, you need one more race. So in total 7.
I believe there are six. After you determine the fastest 5 out of the 25 you can just have one more race and choose ranking 1, 2, 3
