ok I don't know why I am spending time on this but here we go. If the question is from a math exam the answer would be 300/3= 100.
So he would run into 100 needles.
If it's a joke. Then the answer is 0. You can state that he (the man) didn't run into any but the horse did. It would not be very smart to state such a thing because the riddle then would have two flaws
1) The riddle self says "a man.....runs into..."
2) If you decline flaw#1 then you'll have to admit that by the "he" in "How many needles did he run into" actually the man isn't referred at but actually the horse is. (We then also know it's a stallion)
above is written assuming that by "one third of the needles" is ment one third of the needles of the mentioned cactus.
Does this cover the answer to your riddle/question?
