Talking Frogs or Talking Toads?
Test your ability to handle logic with these fun problems
Here is an interesting set of logic problems I came across, clearly designed to test a person’s ability to handle combinations of logic. No mathematical knowledge is required to answer these questions — and that’s what I love about logic problems.
I’ll outline each of the problems first, so you have a chance to have a go at them without any spoilers. Then I’ll outline my solutions.
The distant land of Amphibia is populated by talking frogs and toads, who spend their time in small groups making statements about themselves. Toads always tell the truth and frogs always lie. In each of the following scenes from life on Amphibia, determine which of the animals are frogs and which are toads.
Problem 1
A says “Both B and myself are frogs”.
Problem 2
C says: “At least one of D and myself is a frog”
Problem 3
E says: “Both G and H are toads”. G says “That is true!”. H says “No, that is not true”.
Problem 4
I and J are discussing I, J and K. I says “All of us are frogs”. J says “Exactly one of us is a toad”.
