Here it is:
You are the conductor of a freight train, alone, and realize the train's brakes are shot. There is nothing you can do to repair them, but the train will head up a steady incline and it will eventually stop.
You see 10 men walking on the rails directly in front of you, who don't see the train. On a rip which you can turn into, there is a child playing on the tracks. If you turn, you will kill the child. If you proceed straight, you have a 90% chance of killing each of the men(90% per person). What is your decision, and why do you decide that it is the right choice?

Honestly, this is a situation that even Aristotle would have a tough time thinking about. Assuming this isn't a trick situation, the choice is between virtually killing nine men or one child. The math is easy, killing one child is not as bad as killing nine men, but the justifications are not.
I'll say that it is one of those situations in which there is no proper thing to do. Choose the lesser evil of killing one to save many as opposed to killing many to save one.
You have to apply value to human lives, which is very hard, which is why I find it to be challenging enough to share it with people.

Miserable choice here, presuming that you are aware of both groups, i would continue on towards the 10 men, not only is deliberately choosing to kill a child morally objectionable, the 10 men are adults and should have more common sense than to be dossing around on some train tracks, They would also have at least a little more awareness of whats going on around them than a child. Lastly the child at least has some excuse to be playing on train tracks.
