Are you imagining sealed bags? The bags can be opened, that should answer all your q’s
So bags that can be opened, but that contain each an arbitrary number of coins, but the fake coin bags contain only fakes, and the real coin bag contains only real coins?
So I open them and take one coin as a refenrence (remembering from which bag it came) and compare it to one coin from each oter bag, till I found one that is heavier...
I trust I would feel that the 2oz is heavier than 1oz, so I don't need the bathroom scale at all...

Correct

I’ll customize the riddle for you, change that to 1 oz and 1.1 oz!
4 people take a walk at night. They come to a dark tunnel. Only 2 people could cross the tunnel at the same time. They have a candle that burns exactly 13 minutes.
It takes Sara 6 minutes to walk across, Rivka 5 minutes to cross, Rochel 2 minutes, and Leah 1 minute. How do they all cross the tunnel with the candle?

Hidden:
leah and Rochel cross 2 min
Leah waks back +1 min = 3 min
Sara and rivka cross + 6 min = 9 min
Rochel walks back: + 2 min = 11 min
Rochel and leah cross + 2 min = 13 min

Not sure how to do hidden content on iPhone, anyone?
2 & 1 go (2)
1 comes back (1)
6 & 5 go (6)
2 comes back (2)
2 & 1 go (2)
=13
By the same logic I got to 25.
say the train leaves at 12.
12, 12:30, 1, 1:30, 2, 2:30, 3, 3:30, 4, 4:30, 5, 5:30, 6, 6:30, 7, 7:30, 8, 8:30, 9, 9:30, 10, 10:30, 11, 11:30, 12.

Ok, same thing. The noon train and the midnight train are technically not passing but arriving/departing at the same time. So the answer should be 23.
You come to a fork in the road and you need to get to the castle. There are 2 people there who know which road to take. One always tells the truth and one always lies. Problem is that you don’t know who is the truth-teller and who is the liar. You get to ask only one question to one of them. What question can you ask that will get you to the castle?
On an iPhone you can hide content by sandwiching it between “[]” and “[/spoil]” (without the quotes and with the word “spoil” inside the first brackets as well). I know, it’s a big pain.
