Bob and Rob are identical twins. They look alike in every measurable way, but Bob lies on Monday, Tuesday, and Wednesday, whereas Rob lies on Thursday, Friday, and Saturday. Both of them tell the truth on Sunday.
You come upon Bob and Rob one day and introduce yourself to them.
One twin (twin A) introduces himself as Rob and warns that he will lie tomorrow.
The other one (twin B) looks up in surprise and tells you that [b]he[/b] is Rob. He also says that he lied yesterday and that he will also lie tomorrow.
Who is Bob, who is Rob, and what day of the week is it?

Edited by car15: 10/4/2014 9:37:34 PM[b]SOLUTION[/b] Twin B is obviously lying, since neither person lies, tells the truth, and lies on three consecutive days. Therefore, Twin A must be telling the truth, since both twins cannot lie on the same day. Since it is not Sunday (since B is lying), it can only be Wednesday. Twin A must be Rob, and twin B must be Bob.
-
Rob is twin A and it's Wednesday.
-
Bob is twin B, rob is twin A, and it's Friday.
-
It's wendsday and twin A is bob and twin B is rob but they lied about lieing on certain days
-
Bob it twin A. Its Sunday and rob is lying even though its Sunday.
