The Frog With The Odd Color
Riddle: Ty has four frogs-Lily, Hoppy, Croaky, and Icky–and he needs you to identify their colors. One of the frogs is black and blue, while the other three and black and orange. Assuming that both of the following statements are true, can you guess which frog is black and blue? 1) Lily and Hoppy are of the same color. 2) Croaky isn't black and blue.
Answer: Icky is black and blue. If Lily and Hoppy are of the same color, then both of them must be black and orange because only ONE of the frogs is black and blue. And if Croaky isn't black and blue, then he is black and orange. Therefore, Icky is the only black and blue frog among the four frogs.
