If a vowel is not at the beginning or at the end, it is to be coded as 6.
If a vowel is at the beginning or at the end, it is to be coded as 9.
However, if the same vowel is placed both at the beginning and at the end, it is to be coded as '$' at both the places.
Q. Choose the correct coded form of the following letter group.
PKDEJHI
Explanation
P K D E J H I
Vowels that are neither at the beginning nor at the end are codded as 6, i.e. E will be coded as 6.
Vowels that are either at the beginning or at the end are codded as 9, i.e. I will be coded as 9.
From the above table, the code for P is 7, K is 1, D is 2, J is 5, H is 3.
So, the code for PKDEJHI will be 7 1 2 6 5 3 9.

Q. What will be the code for 'search login american'?
Explanation
Symbols used in the code language:
If number of vowels in the word is 1, then symbol is '@'.
If number of vowels in the word is 2, then symbol is '#'.
If number of vowels in word is 3, then symbol is '%'.
If number of vowels in the word is 4, then symbol is '$'.
Numbers used in code language:
If total number of letters in the word is even, then add 1 to the total number of letters.
If total number of letters in the word is odd, then subtract 1 from the total number of letters.
Letter used in the code is the letter opposite in terms of position to second letter from the left end of the word, as per English alphabet.
Therefore, code for 'search' is 'v#7'.
Similarly, code for 'login' is 'l#4'.
Code for 'american' is 'n$9'.
Hence, code for 'search login american' is 'v#7 l#4 n$9'.
