Answer Posted / alok chandra
Could you please explain me how you got 6 as your answer. I
could do it in a minimum of 11 races. There has to be
atleast 5 races to select 15 horses. The 15 horses then
compete among themselves and best 9 horses are chosen. The
9 horses then run in groups of 5 and 4. From the group of
5, three horses are selected. The horse which comes third
is made to run in the next group as well. We again choose
three horses from the group. So that makes it a group of 5
fastest horses. Then run the last race by which we can
determine the three fastest horses.
