1. (b) First three letters of the word are kept as they are sixth letter comes at fourth place shifting fourth and fifth letters to fifth and sixth places, respectively and the last two letters are exchanged.
2. (b) Each latter of the word has been written two letters back in the coded word, as their positions in the alphabet.
3. (c) Letters of the basic word are written in the coded word in such a way that last and first letters, second last and second letters, third last and third letter and so on are written together in the coded word.
4. (c) The word has been coded in such a way that codes for letter P are OQ (One letter behind and one letter ahead of P in alphabet). Similarly, codes for O are NP and so on.
5. (c) First four letters are reversed, two middle are reversed and then last four letters are reversed. Therefore, the word ADVANTAGES would be coded as AVDATNSEGA. Hence, option (c) is the correct answer.
6. (c) Last letter of the coded word is the next letter of the first letter of the basic word, second last letter is the next letter of the second one and so on in the alphabetical order.
7. (b) Letters of first half of the word are reversed, and than the letters of the second half of the word are reversed.
8. (b) Letters at the odd places are coded one letter ahead, and letters at the even places are coded one letter behind in the alphabetical order.
9. (c) Letters of first half of the word are coded with a gap of 0,1,2 letters in the forward direction, and letters of the second half are coded with a gap of 0,1,2 letters in the backward direction in alphabetical order.
