Paintballing Weekend - Logic 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?
