Jagan lies on Monday Tuesday Wednesday
Pradeep lies on Wednesday Thursday Saturday.
Jagan says I didn’t lie yesterday. Pradeep also says that I didn’t lie yesterday. What
day is today?

• it must be tuesday bcz,
  
  as per assumption one statement is a lie and other one is true.
  
  consider today as monday :
  
  jagan says " i didn't lie yestarday(Satday)" monday he liee(wrong).
  
  pradeep says " i didn't lie yestarday(Satday)" moday he is true but satday he lies(wrong)
  
  consider today as tuesday :
  
  jagan says " i didn't lie yestarday(monday)" tuesday he lies and monday also he lies (TRUE). supports the statement.
  
  pradeep says " i didn't lie yestarday(monday)" tuesday he is true and monday also(TRUE). supports the statement.
  
  ans is tuesday ..
  
  vignesh is correct! :) :) ...

• both can lie on wednesday
  & as we r not sure who is lying,
  so we take maximum possibility that both are lying
  so in that case, both can lie on wednesday (which has taken as yesterday)
  hence, today is THURSDAY.ans.
