[pgn]

Well done all! I realised my I should be X a few hours after submitting my answers, so it goes!

Thanks @Mi-Amigo - glad these don't appear too often 🤣

[TallTrees]

Thank you for my results @Mi-Amigo 

40% and my sanity 😂 not too bad.

Excellent results all round.

[Cleoriff]

Good grief! 😂

I'm pleased I did it now. (I had said to @pgn that I wouldn't be doing it as I found them too hard)

Perhaps my brain is working better than I thought. 😂

Well done everyone and thanks @Mi-Amigo (Leave the next one for another 6/12 or so ...please) 😂🤣

[BobM]

Thanks @Mi-Amigo - good one and well done to all. 👍

I slipped up with a couple of them and I shouldn't have, but they're always so obvious when you get the correct answer.  Ah well, better luck next time. 😜

Well done @Cleoriff 

I must say I initially thought the twins answer was how @Mi-Amigo rationalised it, but then I thought the more elegant answer would be if they were not twins as they were 2 out of a set of 3 or more siblings born at the same time - you win some, you lose some 😂

[Mi-Amigo]

Thank you @pgn @TallTrees @Cleoriff @BobM 

So pleased you took part and well done on your scores.

[jonsie]

Well done and good efforts everyone and special thanks to @Mi-Amigo 

Q3 was so **********!
