The implication was that they couldn't communicate (their mouths were sewn shut or something similar). But, given that they are scientists, they managed to complete the task.

#11 Four gentlemen sat down to play, and they played all night until morning. Each played separately from the others. Some played better, some worse... But in the morning, when they started counting the money they had won, it turned out that everyone had the same amount of money. Explain how this is possible... and WHO are these people...? #12 A dozen people are walking, carrying a dozen loaves of bread. Each man carries 2 loaves, each woman carries half a loaf, and each child carries a quarter of a loaf... How many of each were there...?

#12 I even have 2 options: 1) 8 women (4 loaves of bread), 4 men (8 loaves of bread) 2) 5 men (10 loaves of bread), 1 woman (0.5 loaves of bread), 6 children (1.5 loaves of bread)
#12. 5 men - 10 loaves of bread, 1 woman - 0.5 loaves of bread, 6 children - 1.5 loaves of bread. It took me a whole 5 minutes to realize I could use non-integer numbers =)
#13:
You are in a basement, there are 3 switches. Each of them controls a light bulb upstairs (there are also 3 of them). How, using only these switches (let's assume they are labeled a/b/c), can you determine which switch corresponds to which light bulb upstairs, if you can only go upstairs once?
The Ataman scares me. He solves everything! Solve puzzle #10. I thought and thought, but couldn't come up with anything.
#13
You can short-circuit one (the light bulb will burn out), turn one on, and leave the other one off.

#14 You have two coins in your hand, with a total value of fifteen kopecks. What are these coins, if one of them is not a five-kopeck coin? #15 A man spent three days in the hospital. He was not sick and did not suffer an injury, but he had to be carried out upon discharge. Why?

#13 I messed up, but I should be able to answer now. Light one lamp and wait for 5 minutes. Then turn it off, turn on another one, and go upstairs. The first lamp will be warm, the second will be lit, and the third will not be lit.

Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up, Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil; Rejoiceth not in iniquity, but rejoiceth in the truth; Beareth all things, believeth all things, hopeth all things, endureth all things. Charity never faileth...
