The secret agent X emailed a code word to his head office. They are "AIM DUE OAT TIE MOD". But four of these five words are fake and only one contains the information. The agent X also mailed a sentence as a clue - if I tell you any one character of the code word, you would be able to tell the number of vowels in the code word. Can you tell which is the code word?

DUE?

(the only one that contains a letter (U) not in any other words?)

MOD.

Because it has just 1 vowel .Not sure though.

It must be TIE. This is the only word where all 3 letter appear in words with 2 vowels. Therefore, any of the 3 letters would give the answer of 2 vowels.

The only word with singular vowel is MOD. Given any of the letters in that, I'd not know if is one or two letters (tell me M, and it can be MOD - 1 vowel, or AIM - two vowels), and I will beuncertain if it has 1 or 2 vowels. Same for O and D. It must be a word without 'M', 'O' or 'D'. = TIE.

Does that make sense, my gut says it's right
