N a bike race: julie came in ahead of roger. julie finished after james. david beat james but finished after sarah. in what place did david finish?

Respuesta :

Lets represent Julie, Roger, James, David and Sarah by the numbers:
 
J, R, Ja, D and S.

If Julie and Roger are the first 2, J<R means that Julie beat Roger, and J=1, R=2.


"julie came in ahead of roger" : J<R

"julie finished after james"  : Ja<J

"david beat james but finished after sarah":             S<D<Ja
 

Now since       Ja<J and J<R      then    Ja<J<R


S<D<Ja and  Ja<J<R , means that  S<D<Ja<J<R

thus S=1, D=2, Ja=3, J=4, R=5
