  If today is Thurs, yesterday was Weds. Now B should NOT lie on Thurs so Weds was one of the days he lies on....Correct. And C should lie on Thurs so Weds was NOT one of the days he lies on...Correct. So It's THURSDAY.

• On thursday B will not lie so he said that said truth that he lies on yesterday and C lies on thursday and he told that he lied on wednesday. so the day is thursday.

• thursday.
• 13 years agoHelpfull: Yes(3) No(0)
• ANS is THURSDAY
• 13 years agoHelpfull: Yes(3) No(0)
• yesterday was WEDNESDAY
  as on thursday c lies but b does not lies on thursday
  means B is telling the truth to A as B lies on wednesday so today he is true
  but the other fellow c lies on today but not on wednesday so he is lying.
  .................now let us discuss how WEDNESDAY would be the answer????
  B lies on-->>monday,tuesday,wednesday
  B doesnot lies on-->>thursday,friday,sat,sun
  C lies on-->>thurs,fri,sat
  C doesnot lies on-->>sun,mon,tues,wed
  now considering ur answer let there was thursday yesterday than on friday B doesnot lies n also on thursday he doesnot lies so there is a contradiction in the statement similar case is for c....................u may try any of the day as yesterday except wednesday u would conclude similar conclusions n the contradiction persists
  so yesterday could not b anyother day except WEDNESDAY
