Note : In a code the 10 th letter J of the English alphabet is coded as Z and for any k ≠ 10, the k th letter is coded as r th letter where r is the remainder when k + 2 is divided by 26. (For example, the 7 th letter G is coded as 11 th letter K since 5 × 7 + 2 = 37 leaves remainder 11 when divided by 26). The reverse process is used for decoding. Using these processes of coding and decoding answer Q. Nos. 56 to 60.
