A man decides to throw a party but forgets to print the invitation cards. So he decided to give a particular code to every guest which they have to speak on arrival. When the first guest arrived the watchman said 12 and the guest said 6 and was allowed. For the second guest the watchman said 6 and the guest replied as 3 and he was allowed. For the third guest the watchman said 8 and the guest said 4 but the guest wasn't allowed. What code must the guest say in order to enter the party?
The code is the number of letters in the word
example-
twelve = 6 letters
six = 3 letters
eight = 5 letters
hence guest must say 5 to get in
