On the table are scales with two bowls and 9 identical coins. One of them is fake, its weight will be less than the rest. How to determine it with just 2 weighings?
Answer: At the first weighing 3 coins should be put on one bowl and the same on the other. If the scales are balanced, then a fake is among the last 3 pieces. At the second weighing you need to take two coins and put them on the bowl. If they weigh the same, then the third coin is not real. If some was easier, then it is a fake. But when, after the first weighing, one of the heaps turned out to be less in weight, then the desired coin is among those three. It is necessary to calculate it by the principle of the second weighing.

He lived with Thomas.

And, having found peace,
He blessed them on the path
On a long, difficult.
Raising his nose proudly to the sky
Steps first brother
Proud from heels to hair,

What he sees all around
As if everyone owes him.
Enough about him.
Their third brother is a big walker,
He knows a lot about girls.
He recognizes one lesson:
I'm in the female herd - the wolf!
Fourth evil, like a hundred devils,
Greedy fifth brother
And in their idle laziness

The puzzle is very difficult, to correctly answer all the questions you need to understand some aspects, and of course you need to connect logic and attentiveness.
Answer: 1. Obviously, recently: experienced tourists in a hollow will not break a tent.
2. In all likelihood, not very: they do not clean the fish from the head, it is inconvenient to sew a button with too long thread, it is necessary to cut the branch with an ax on the block.
3. Shipping. This is evidenced by a navigational mast standing on the shore.
4. From left to right. Why? See the answer to the next question.
5. The navigation mark on the river bank is set in a strictly defined manner.

The depth of the river is 125 cm (rectangle 1 m, a large circle of 20 cm and a small circle of 5 cm), the width of the river is 30 m (a large circle of 20 m and 2 small ones of 5 m each). Such signs are installed 500 m before the roll.
6. Not for long. There is a wind: the floats of fishing rods drifted upstream.
7. The sunflower is obviously broken and stuck in the ground, since its “cap” is not facing the sun, and the broken plant will not grow again.
8. Not further than 100 km, at a greater distance from the body, the antenna would be a more complex structure.
9. The guys probably have bicycles: a bicycle wrench is on the ground.
10. No. Here they like dumplings. Mud hut, pyramidal poplar and a high height of the sun above the horizon (63 ° - in the shade of a sunflower) show that this is a Ukrainian landscape.
11. Judging by the height of the sun above the horizon, it happens in June. For Kiev, for example, 63 ° is the highest angular height of the sun. This happens only at noon on June 22. The newspaper is dated August - therefore, at least last year’s.
12. Not at all. The plane produces agricultural work.
