One day Rapunzel meets Dwarf and Byte in the Forest of forgetfulness. She knows that Dwarf lies on Mondays, Tuesdays and Wednesdays, and tells the truth on the other days of the week. Byte, on the other hand, lies on Thursdays, Fridays and Saturdays, but tells the truth on the other days of the week. Now they make the following statements to Rapunzel – Dwarf: Yesterday was one of those days when I lie. Byte: Yesterday was one of those days when I lie too. What day is it?

a]Thursday
b]Tuesday
c]Sunday
d]Monday

• Its Given:
  Dwarf Lies on-> Monday,Tuesday & Wednesday.
  Dwarf Speak Truth on->Thursday, Friday, Saturday & Sunday.
  
  Byte Lies on->Thursday, Friday & Saturday.
  Byte Speak Truth on-> Sunday, Monday, Tuesday & Wednesday.
  
  Lets Do So Some Reverse Checking->Start With Thursday
  
  Dwarf->Yesterday was one of those day when i lie, so if today is Thursday then yesterday was Wednesday so the statement is true because on Thursday Dwarf speak truth and the given statement is true that Wednesday he speaks lie.
  
  Byte->Yesterday was one of those days when I lie too, so if today is Thursday then yesterday was Wednesday so the statement is false, Byte lied because on Thursday Byte lies and the given statement is false that Wednesday he speaks lie because actually on Wednesday he speak truth.
  
  
  So, Answer is Thursday (a)
  
  P.S -> If you check further for Tuesday, Sunday or Monday, it will not full fill the above rules hence all other options are wrong.

• answer is thursday
  as the condition says that the dwarf lie on monday, tuesday & wednesday so they will speak truth that they lied on thursday also on the other side the bytes speak lie on thursday and will tell that they spoke lie on wednesday. So the day has to be thursday as no other option satisfies the condition also.
