are you suggesting that is what i did and joined them in lying?
........mon ...tue ...wed ... Thu ... Fri ... Sat ...sun
jim ..... T ....t .... T.... T.... L.... L ,,,, l....
Freda .....t ....l .... L.... L..... T..... T.... T....
Jim is either telling the truth, or he's lying. If he's telling the
truth today, and he says he lied yesterday, then he must have lied yesterday. On what days can this happen? (that is, on what days does jim have a t preceded by an l on the previous day?) if you'll look at the table, you'll see that it can happen only on monday.
If jim is lying today, and he says he lied yesterday, then he must have told the truth yesterday. On what days can this happen? If you'll look at the table, you'll see that it can happen only on friday.
Same with freda, she is either telling the truth, or he's lying. If she's telling the truth today, and she says he lied yesterday, then he must have lied yesterday. When does freda have a t preceded by an l on the previous day? Friday.
The other case? T and then an l? This happens only on tuesday.
Therefore, the day you ask about is friday.
