Answer / ajay
25 horses can be grouped into 5 . like a,b,c,d,e. each group contains 5 horses. so there are 5 tracks and 5 groups so each race for every group. rank 1 horse from every group will be eligible for further and last round. the final round is for 5 horses. they are top 5.
so the minimum possible races will be 6 only.
