US Version

Let's assume for a moment that cow A is a Troomoo. If you assume this to be true and go through the statements for each cow, you should come to the conclusion that you must have three Troomoo cows and two Nowheys. Since you now this to be false, you know that your original assumption must be incorrect.

Solution

Incorrect

Too bad!

US Version

Think hard about the clues you've been given and try again.

UK Version

Think hard about what the cows said and try again.

Correct

That's right!

US Version

Cows A, C, and E are Nowheys. If you assume each cow to be a Nowhey or a Troomoo and run through each of the cows' statements, you'll eventually realize that all statements are true when cows A, C, and E are assumed to be Nowheys.

UK Version

Cows A, C and E are Nowheys. If you assume each cow to be a Nowhey or a Troomoo and run through each of the cows' statements, you'll eventually realise that the only time there can be three Nowheys is if they are A, C and E.
