Question

A casino manager wished to check the bias on the roulette wheel, so he asked six of his croupiers to report back to him at the end of the week with the number on the wheel which had been most successful.

The wheel consisted of 36 numbers 1 to 36 and there was only one wheel.

The croupiers were named A - F and each had a different answer:

A said, "It was even."

B said, "It was odd."

C said, "It was prime."

D said, "It was a square (square number 1, 4, 9... etc)"

E said, "It had at least one digit 2 in it."

F said, "It was a single digit."

However two of the croupiers were lying. What is the number?

I'd have to say it was the number 2

It is even, prime, has a 2, and is a single digit. It is not odd or a square.

However, how the ball is tossed has so much to do with any kind of consistency that you might see on a roulette table, that I highly doubt 6 different croupiers would report all the same number.

I think it was the number 2.

Reasoning: A and B directly contradict each other so one o them is lying. C and D directly contradict each other so one of them is lying. Since we know that there are only 2 liars, E and F must be telling the truth. Therefore the answer is a single digit number that conains the digit 2.

Good job both of you. That's the correct reasoning.

SORRY
D AND A NOT A AND E

does that mean F is telling the truth?

Oh and a big thanks to CJ for convincing me to post some riddles.
