After a local Post Office burglary, four suspects were being interviewed. Below is a summary of their statements.
Police know that each of them told the truth in one of the statements and lied in the other.
From this information can you tell who committed the crime?
It wasn't Derek
It wasn't Brian
It wasn't Charles
It was Derek
It was Alan
It wasn't Derek
It was Charles
It wasn't Alan

Hint: Remember that each of them told the truth in one of the statements and lied in the other.
Answer: Brian robbed the Post Office.
We know that each of them told the truth in one of the statements and lied in the other.
So according to Alan, as one of his statements is false, it must have been either Derek or Brian.
If it was Derek then Brian's statements would both be true, which isn't allowed.
Therefore it was Brian, which agrees with Charles and Derek's statements.

During a recent BrainBashers thinking contest, the total number of points scored by the first six players was 103 and every score was above zero.
The first player scored half the points of the second player, who in turn scored 6 points fewer than the third player.
The third player in turn scored two thirds the points of the fourth player.
The fifth player managed to score the same number of points as the difference between the first and fourth player's points.
Finally, the sixth player scored 14 fewer than the fifth player.
Can you determine how many points the sixth player managed to score?

Hint: The fourth player is the key to this tricky question.
Respectively the scores were 7, 14, 20, 30, 23, 9.
If the six player were A, B, C, D, E and F we know that:
A + B + C + D + E + F = 103 
A = B ÷ 2
B = C - 6
C = D x 2 ÷ 3
E = D - A (see note at end)
F = E - 14
Since D is the letter we're missing information for, it's best to find all of the other letters in terms of D. These steps are left as an exercise, but the result is:
A = (2D - 18) ÷ 6
B = (2D - 18) ÷ 3
C = 2D ÷ 3
E = (2D + 9) ÷ 3
F = (2D - 33) ÷ 3
We can then use these all in  to find that D = 30. Which allows us to find F = 9.
Small note: if we chose E = A - D (instead of E = D - A) we'd end up with a negative value for E, which isn't allowed.
