1)Creus
2)Moscow
3)Tehran

I'm sure the first is wrong

2 and 3 are correct, 1 has the right letters but is not; you worked out the trick in them then xD

Sucre?

I can't think of any combination that I've heard of.

[ElliotMajor]

Me neither, can't get that first one :/

[Chaos]

What was the logic behind it anyway? I see you've been taking the first few letters of every element, but it's tough to solve.

Sucre?

Correct

It's just the chemical symbols of the elements in an anagram :L

Time to disturb the dead...

In a faraway land there is a prison with 100 inmates. The wicked warden is plotting a conspiracy to reduce the number of prisoners: Each prisoner will get a number from 1 to 100, he will enter a room with 100 drawers numbered from 1 to 100, and in each drawer a note numbered from 1 to 100. The prisoner can open 50 drawers, and if he finds his number in one of them, he will be saved from death, if not he will be executed.

You begged the warden to spare the prisoners, but he refused. However, he allowed you to talk to all of the prisoners and give them a strategy for picking the drawers. He also allowed you to enter the room before the whole process starts and exchange at most one pair of notes in the drawers (note that you must speak to the prisoners before entering the room). All drawers are closed when a prisoner enters.

What will you tell the prisoners? How many can you save?

50

[Chaos]

Explanation?

[jake1456]

since 50 drawers can be opened there will be a 50% chance to find their number

[Chaos]

How many can you save for sure? No randomness.

I could think of a way to at least save 98 of the prisoners. The first prisoner should open 50 drawers with the numbers 1 to 50. With luck, this guy finds his own number. If not, we have a single prisoner gone.

Before he entered the room, I told him to take all the notes he gathered from the drawers, and put them back into a single one, drawer number one.

I'll tell the next prisoner to check drawer 1. There is a chance he will find his number in there. If not, he can still open another 49 drawers. There is a chance he won't survive this test either. Luckely, I told him to leave drawer number 100 alone and put the 49 gathered notes in drawer 1.

I'll tell the next prisoner to check drawer 1 and 100 and get the contents of drawer 100 in in the first one.

I'll tell the next 97 prisoners to check drawer 1, which will surely contain their numbers.
