This is wrong if 5 and 7 were both right...there'd be "at most 3 AND at most 4" true statements

I don't see your logic? The only way I can justify the statements is 1 is true the rest false. If as you say 5+7+9 true rest false you can't have 7+9 true as that makes three trues and seven falses which cancels 7+9

It says "AT MOST", not "EXACTLY", hence at can be anything, but AT MOST it has to be a certain value.

If it says 'You chose "True" at most twice.' then it could be once, twice, or none at all.

When the instructions said "Choose true or false to these statements, and your answers must be consistent", I took that to mean it had to be the same to every question, consitently true OR consistently false..which would make the answer false. Was not aware that you were looking to find which particular ones were true or false. The instructions are not clear in that respect.

False to all of them.

I am sorry, but that was too complicated! Teasers are supposed to be fun, that is the point!

Well, I had fun AND got the correct answer!

I do have to admit though that I found myself wondering what you meant by the answers needing to be consistent. Perhaps it should have said "your answers must be accurate". Anyway, I still figured it out and enjoyed myself along the way.

"Consistent" is opposed to "contradictory".

consistent in this case means one answer can't change the value of another, or if it does you must change all the values until they are all correct at the same time.

What about this: I simply choose "false" for all the statements. Therefore, I've got ten falses, and obviously none of the stataments is true!

Great teaser!

You can't choose false for each statement because then you would have chosen true zero times and therefore statements 1,3,5,7,9 should all be true.

As a previous comment stated, "at most five times" means 0, 1, 2, 3, 4, or 5 times.
