Test Level 3: Coding Decoding (September 12) - CAT MCQ

This is the right answer because it follows the condition (ii) as both first and last letters are vowels. Both A and U are coded as &.

Both first and last letters are consonants, so it should follow condition (i).
The code of STPXW is 36417.

E G T A R L Q E

Vowels at the beginning and the at the end are same, so they are to be coded as $, and as 6 in between.
$ 5 1 6 5 3 8 $ as it does not tally with the given option.

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.

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'.

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.
So, code 'v%6' stands for 'general'.
Code 'y%6' stands for 'abstain'.
Code 'm%9' stands for 'indigent'.

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 'argument' is 'i%9'.
Similarly, code for 'reverse' is 'v%6'.
Code for 'end' is 'm@2'.
Hence, code for 'argument reverse end' is 'i%9 v%6 m@2'.

If total number of letters in the word is even, then symbol is '@'.
If total number of letters in the word is odd, then symbol is '#'.
If the number of letters in the word is odd, then 1st letter of the code is 3rd letter from the left end of the word, and last letter of the code is the letter opposite to 2nd letter from the left end of the word, as per English alphabet.
E.g. Code for 'trees' is 'e#i'.
'e' is the third letter from left, and 'i' is opposite to 'r' in the alphabet.
If the number of letters in the word is even, then 1st letter of the code is 3rd letter from the right end of the word, and last letter of the code is the letter opposite to second-last letter of the word, as per English alphabet.
E.g. Code for 'team' is 'e@z'.
'e' is the third letter from the right end of the word.
@ is the symbol as total number of letters is even.
'z' is opposite to second-last letter (a) of the word, as per English alphabet.
Code for 'heinous' is 'i#v'.
Code for 'crime' is 'i#i'.

The code for each word consists of three elements.
First element is the number which is three more than the number of letters in the word.
Second element is a symbol assigned to the first letter of the word. Symbols are assigned as per the following table:

Third element is the last letter of the word.
'8@O' is the code for a 5-letter word starting with R and ending with O.
'8!C' is the code for a 5-letter word starting with M and ending with C.
'8$T' is the code for a 5-letter word starting with B and ending with T.

The code for each word consists of three elements.
First element is the number which is three more than the number of letters in the word.
Second element is a symbol assigned to the first letter of the word. Symbols are assigned as per the following table:

Third element is the last letter of the word.
So,
'race' is coded as '7@E.
'back' is coded as '7$K'
'mom' is coded as '6!M'
