Another puzzle,
by
Paul Conroy
Now this one is actually one of the hardest puzzles ive ever worked on, just got it after probably spending about 2-3 solid hours trying to work it out, have fun.0 Replies 289 weeks
To solve this problem you must decode another message and answer the question within it. Instead of a using a Caesar Cipher, we have used a Substitution Cipher,
http://en.wikipedia.org/wiki/Substit...
which is a more difficult code to break. In a substitution cipher, each letter is replaced with another letter, but it is not a simple shift. For example, if we replaced "h" with "p", "e" with "f", "l" with "a" and "o" with "r" then "hello" would become "pfaar".
Substitution ciphers can be broken by looking at how common different letters are. In English the most common letter is "E". Following E, the next most common letter is "T", then "A", then "O", then "I", then "N" and then "S".
In the question, before it was encoded, the most common letters were "ETAOINS", in that order.
Your code is -

This is one i did a long time ago, took a while to figure it out but it is a good one, ive tried people on it a lot and there are so many people that cant get it. Even my honours maths teacher couldnt get it for a while.0 Replies 290 weeks
Three women go into a bread shop one after another. The first woman buys half of the total number of loaves in the shop and an extra half loaf (So if there were 21 loaves in the shop, she buys 10.5 + 0.5 = 11 loaves). The second woman buys half of the loaves left in the shop and an extra half loaf. The third woman then goes in and buys half of the remaining loaves and an extra half loaf. When the third woman leaves the shop, there are no loaves left. How many loaves were in the shop to start with?
