Conditions:
I. If the first element is an even number and the last is an odd number, the codes for the first and last elements are to be interchanged.

II. If both the second and third elements are even numbers, the code for these two will be K.

III. If the first element is a number and the last a symbol, the last element code is to be used for the first element also.

What will be the code for 8%7$9@?

Correct Answer: (d) XDHANX
Solution:

The elements given in the question are “8%7$9@”
“8%7$9@” will be coded as “LDHANX”
The third condition applies to this group of t number/symbol.
After changing the code
“8%7$9@” = XDHANX

Letter/SymbolsOERLAV&S@
           Code761482359


Condition 1: If a word starts with a vowel but ends with a consonant, then codes for first and last letter to be reversed.

Condition 2: If there are more than two vowels in a word, then first vowel is to be coded as 1, second vowel as 2 and so on.

Condition 3: If a word starts with a consonant and also ends with a consonant, then vowels are to be coded after coding all the consonants.

What is the code for “ALOEVERA”?

Correct Answer: (b) 14232415
Solution:

The elements given in the question are “ALOEVERA”
“ALOEVERA” will be coded = “8 4 7 6 2 6 1 8”
The second condition applies to this word, which states that if there are more than two vowels in the word then first vowel is to be coded as 1, second vowel as 2 and so on.
After changing the code for vowels
“ALOEVERA” = 14232415

     CodeTDCRGBYHNJPLQSDFZ


Conditions:
I. If the first element is an even number and the last is an odd number, the code for the first and last elements will be K.

II. If both the second and third elements are even numbers, the codes of these two are to be interchanged.

III. If the first element is a number and the last a symbol, the number code is to be used for the symbol also.

What will be the code for 6$8^&3 ?

Correct Answer: (a) KHDLSK
Solution:

Given, 6$8^&3 → PHDLSG (required code)
As per given instructions, Question follows only Condition (i)
So, from condition (i) → (the code for the first and last elements will be K)
i.e. PHDLSG → KHDLSK (required answer)
