Here are the answers for 'Tickle your brain'.
See if your answer is right or wrong ?
  We know that Shyam tells the truth on a single day of the week.If the statement on day 1 is untrue, this means that he tells the truth on Monday or Tuesday. If the statement on day 3 is untrue, this means that he tells the truth on Wednesday or Friday.Since Shyam tells the truth only on one day, these statements cannot be untrue.So, exactly one of these statements must be true, and the statement on day 2 must be untrue.
Assume that the statement on day 1 is true. Then the statement on day 3 must be untrue,which follows that Shyam tells the truth on Wednesday or Friday. So, day 1 is a Wednesday or a Friday. Therefore, day 2 is a Thursday or a Saturday. However, this would imply that the statement on day 2 is true, which is impossible.From this we can conclude that the statement on day 1 must be untrue. 
This means that Shyam told the truth on day 3 and that this day is a Monday or a Tuesday. So, day 2 is a Sunday or a Monday. Because the statement on day 2 must be untrue, we can conclude that the day 2 is Monday.
So, day 3 is a Tuesday. Therefore, the day on which Shyam tells the truth is Tuesday.

I could not blog for a long time. However, I had been busy reading Books and I read almost many classics.

Well, for a quick post, here is 'Tickle your Brain'

Shyam is a strange Liar. He lies on six days of the week but on the seventh day, he always tell the Truth.

He made the following statements on three successive days.

Day 1: I lie on monday and tuesday
Day 2: Today, its Thursday, Saturday or Sunday
Day 3: I lie on Wednesday and Friday

On Which day does Shyam tell the truth?
