case1

The murderer was the mother.

We know from (3) that the youngest person was not the victim, from (4) that the youngest person was not the helper and from (6) that the youngest person was not the killer. The youngest person can only have been the witness therefore. If we make up a chart there are now three possible combinations:

Oldest person (father) H H M

Next to oldest (mother) V M H

Next to youngest (son) M V V

Youngest (daughter) W W W

(H = Helper ; V = Victim ; M = Murderer ; W = Witness)

We can work out from (5) that the father was the oldest, from (2) that the youngest person must have been the daughter. Therefore the next to the youngest must have been the son and the next to the oldest, the mother.

Of three possibilities: the first is impossible (from (3) – the youngest person and the victim were of different sexes); the third is also impossible (from (1) – the witness and the helper were of different sexes). Therefore only the second possibility holds – and the mother was the murderess

Case 2

The killer was Donna. 

The initial letters of the names of the rooms where the notes were found spell out her name.

Case 3

The gang boss is Billy Goats.

If you read the message upside down you'll notice that it reads: "Bill is boss. he sells oil" 

Case 4

Alice arrested him right away because there was no way he could have known where the body was unless he'd put it there -she hadn't revealed this in the conversation.

5 Coconut confusion -you get one point for the correct answer in your own words

The question is a trick that doesn't make sense. What is given should equal what is received. It does not make sense to add what was given by Alice's tribe (12 coconuts) to what was stolen by the trader (2 nuts).

Although they initially gave 15 coconuts, the total the three men ultimately gave is 12, as they get three ones back. So from the 12 Alice's tribe gave, the chief receives only10 and the trader receives the 2. 15 - 3 = 10 + 2

8 The Matrix has you -you get one point for this correct answer

You carefully cut each of the three pills in half, and carefully separate them into two piles, with half of each pill in each pile. You do not know which pill is which, but you are 100% sure that each of the two piles now contains two halves of type B and one half of Type A. Now go back into the type A bottle, take out a pill, cut it in half, and add one half to each stack. Now you have two stacks, each one containing two halves of type A and two halves of type B. Take one stack of pill-halves today, and save the second stack for tomorrow.

9 Here be dragons -you get one point for this correct answer

Carl the Crusher won the contest. (by process of elimination)

Eve the Evil, first born of the king, could not be the winner because the winner was not the king's son or daughter (since the winner and their parents were honored by the King.)

Bob the Bold, whose only weapon was a spear, could not be the winner because the winner used an ax to kill dragons. (Only Donna used two weapons.)

Donna the Dragonslayer, who killed 4 dragons with her ax (and 5 dragons with her spear), could not be the winner because the winner killed more than a half dozen dragons with an ax.

Alice, whose horse was a gelding (castrated horse), could not be the winner because the winner's horse was retired for breeding after the contest.

Carl the Crusher must have killed at least 10 dragons because Donna killed a total of 9. More than a half dozen could mean any number greater than 6, including all those higher than 9.
