OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (opcode):

Full riddle: Jim tells lies on fridays saturday and sunday . he tells the truth on all other days. freda tells lies on tuesday wednesday and thurdays .she tells the truth on all other days if they both say yesterday i lied then what day is today?

OpenStudy (anonymous):

THORSDAY idk Tennant Tuesday?

OpenStudy (anonymous):

Answer is Friday

OpenStudy (opcode):

Correct!

OpenStudy (anonymous):

:)

OpenStudy (anonymous):

How did you get Friday?

OpenStudy (abb0t):

Jim is a pathalogical liar.

OpenStudy (anonymous):

Assume that today is Monday. Both people tell the truth on Monday, so the statement ‘Yesterday I lied’ must be true for both. But yesterday was Sunday, and only Jim was lying yesterday. Because Freda told the truth on Sunday, her statement is false.

OpenStudy (anonymous):

So its a contradiction because Freda is supposed to tell the truth on Monday. So today is not Monday.

OpenStudy (anonymous):

Oh, that makes sense, you are so smart @Luis_Rivera

OpenStudy (anonymous):

Assume that today is Tuesday. Jim is telling the truth, so when he says ‘Yesterday I lied,’ it is supposed to be true. But yesterday was Monday, and Jim tells the truth on Monday. So today can’t be Tuesday. The same aplies for Wednesday and Thursday, and in Freda’s behalf on Saturday and Sunday. Theres a contradiction for every day except Friday, so all days except Friday have been eliminated. Answer is Friday
