We know that Richard tells the truth on only 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 Richard tells the truth on only one day, these
statements cannot both 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, from which follows
that Richard 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 Richard
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 day 2 is a Monday. So day 3 is a Tuesday. Therefore, the day
on which Richard tells the truth is Tuesday.

He tells the truth on TUESDAY because:
Day1 (Sunday) I lie on Mon and Tues is a LIE
Day 2 (Monday) Today it's Thurs, Sat or Sun another LIE
Day 3 (Tuesday) I lie on Wednesday and Friday - the TRUTH
It won't work any other way....
