I landed on the island of Knights and Knaves. There are solely 2 kinds of folks on the island, knights who all the time inform the reality and knaves who all the time lie. There are 2 leaders of the complete island, Raymond and Martin. Note that Raymond and Martin can each be knights, each be knaves or it may be that one is a knight and one is a knave.

I discovered them each on the similar time, one in a Red hat and one in a Blue hat however I used to be unsure of who was who.

I requested each of them: “Is Raymond a Knight?” Only the one with the blue hat answered, and I can not keep in mind what he stated. But I do keep in mind that at that time I used to be in a position to inform who was Raymond and who was Martin.

What colour was Raymond’s Hat?
