My friend is studying Maritime technologies. He was given a logical test, where there was the following question:
A paper message was found lying on the street near shop AKVAPLUSS with such content:
Decrypt the code to discover the secret message.
- The test ended a week ago, we are simply interested in the way it can be decrypted, because all the ways we tried didn't work.
- The question was 4th in the test if it helps.
- Finally the teacher answered the e-mail, but he didn't give the answer to the puzzle, however he gave a hint (how we should find out that ourselves I don't know):
Place under the message the word "akvapluss"
EDIT: Clarified puzzle and found out that teacher was made unique puzzles for each student, and my friend is from
