Answer:
Walking along, Tintin overheard the two island gate guards, Thomson and Thompson chatting amongst themselves.
Thomson : He told us we have consecutive letters on our papers
Thompson : Yeah he told me too.
Thomson : I don't know what your letter is.
Thompson : Neither do I know your letter.
Thomson : Now I know.
Tintin listened this conversation and wondered what the two letters could be. When he was
about to leave the island, Thomson stopped him and told him to say the password, which
were the two letters.
Maximum of how many attempts does Tintin need to make to have the correct pair of
letters, and thus pass successfully?
