My ans is 12. I will explain with a diagram
5 5 5 5 5 -> now 5 races each with 5 horses
| | | | |
3 3 3 3 3-> selected 3 toppers from each race so tot 15
horses remaining
5 5 5-> now again 3 more races ie tot 8 races yet
| | |
3 3 3-> selected 3 toppers from each race so tot 9
horses remaining
5 4-> now again 2 more races ie tot 10 races yet
| |
3 3 selected 3 toppers from each race so tot 6
horses remaining
5 _> one more race tot 11 races
|
3 + 1
4 _> one more race tot 12 races
|
3
So tot no of races 12.
But here we assume tht two horses never reach the
destination at the same time :-) if we consider that then no
of races will be much more.
