Challenging riddles with answers: views

You can find a variety of puzzles with answers: complex and funny, mathematical and historical, with and without a catch. The result of such brain training is developed thinking and imagination. But instead of arguing for how long difficult complex riddles with answers are, it is better to go straight to practice.
In this article, the clue will not be placed after the assignment itself, but a little lower, in order to at least slightly support the intrigue. Complex puzzles with answers will be numbered accordingly.
Weighing tasks
This is a classic of the genre. Challenging puzzles with weighting answers are some of the most popular. You can take a piece of paper and a pen and try to draw diagrams. This is better than solving them simply in the mind. Below are two logical puzzles with complex answers.
1. 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?
2. There are 10 bags full of coins. The number of them in each of the bags is the same. In nine of them, all the coins are gold, and each weighs 5 grams, and in one - all are fake, and they, accordingly, are lighter - 4 grams. It is necessary to determine this bag, but weighing can be done only 1 time.
Answers 1. At the first weighing, 3 coins should be put on one bowl and the same amount on another. If the balance is balanced, then the 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 fake. If some turned out to be easier, then it is a fake. But when, after the first weigh-in, one of the heaps turned out to be less in weight, then the desired coin is among those three. It must be calculated according to the principle of the second weighing.
2. First you need to number the bags. Next, take 1 coin from the first, 2 from the second, 3 from the third, etc. Then you need to weigh these 55 coins. If they were all gold, then their total weight would be 275 (55 by 5) grams. But if one gram is missing, then fake coins are in the first bag, if two are in the second bag (of which 2 pieces were put on the scales, each of which is 1 gram lighter than the others), etc.
Complex riddles with a trick and answers
Such tasks not only entertain, but also develop the ability to think outside the box. Very complex puzzles with answers and tricks are very different: mathematical, economic or based on life situations. To find the right answer, you often need to carefully read the terms of the assignment again, and then everything becomes clear. Very often, the catch is a play on words or in their sequence, and in order to confuse, a lot of unnecessary details, such as numbers, have been added. The following are complex puzzles with a catch and answers. To solve them, you need not only attention, but also a sense of humor.
