Paintballing WeekendLogic Puzzles

During an exciting weekend of paintball, four friends were having great fun.

The paintballs came in blue, green, yellow and red.

Coincidentally, the four friends had T-shirts in those same colours.

Billie used blue paintballs.
The person in the green T-shirt used yellow paintballs.
Charlie was not wearing a red T-shirt.
Drew used green paintballs and wore a blue T-shirt.
Alex was the only person who used paint which was the same colour as their T-shirt.
Can you tell which colour paint they each used and the colour of their respective T-shirts?

Puzzle 18 


The Miller next took the company aside and showed them nine sacks of flour that were standing as depicted in the sketch.

"Now, hearken, all and some," said he, "while that I do set ye the riddle of the nine sacks of flour.

And mark ye, my lords, that there be single sacks on the outside, pairs next unto them, and three together in the middle thereof.

By Saint Benedict, it doth so happen that if we do but multiply the pair, 28, by the single one, 7, the answer is 196, which is of a truth the number shown by the sacks in the middle.

Yet it be not true that the other pair, 34, when so multiplied by its neighbour, 5, will also make 196.

Wherefore I do beg you, gentle sirs, so to place anew the nine sacks with as little trouble as possible that each pair when thus multiplied by its single neighbour shall make the number in the middle."

As the Miller has stipulated in effect that as few bags as possible shall be moved, there is only one answer to this puzzle, which everybody should be able to solve.

Sacks 7 28 196 34 5

Puzzle 20 


A very long time ago, at the beginning of the week, I was given some money for my birthday.

On Monday, I spent a quarter of the money on clothes.

On Tuesday, I spent one third of the remaining money on music.

On Wednesday, I spent half of the remaining money on food.

Finally, on Thursday, I spent the last £1.25 on a book.

How much birthday money did I receive?
