Now after 26, all the numbers that are divisible by 3 if subtracted by 40 can be obtained.
After 46, all the numbers will fit into one of the above categories and thus all such numbers can be obtained. But 43 will be last number that will not fall into one of the above categories.
44 = 20 + 6 * 4, 45 = 6 * 6 + 9

#390 - Crack The Code Puzzle

During a secret mission, an agent gave the following code to the higher authorities
AIM DUE OAT TIE MOD

However the information is in one word only and the rest are fake. To assist the authorities in understanding better, he also sent them a clue – If I tell you any one character of the code, you can easily find out the number of vowels in the code word.

Can you find out the code word?

Crack The Code Puzzle

The code word is TIE.

Suppose if you are told a character of MOD, then you can’t identify if the number of vowels are one or two. Suppose that the character you are told of is M, then you can associate two words with it i.e. AIM (that has two vowels) and MOD (that has 1 vowel). You can say the same regarding other characters O and D as well.

Thus all those words that comprises of M, O or D in them can be ruled out. This points us to TIE. If you check with the characters of TIE, you will agree that it stands true for each of the characters of the word. Thus this is the code word.
