I got a chocolate bar for Julian. Since he also likes maths, he has to solve this riddle to get it. The chocolate is in one of three boxes, red (R), green (G), and blue (B). On box (R), it’s written: It’s not here. On box (G), it’s written: It’s here. On box (B), it’s written: It’s not in (R). We know that at least one box tells the truth and at least one box is lying.
