Coding Decoding

Step 1: Compare the letter shifts from "DENMARK" to "FCPKCPM":

- D → F (shift by +2)
- E → C (shift by -2)
- N → P (shift by +2)
- M → K (shift by -2)
- A → C (shift by +2)
- R → P (shift by -2)
- K → M (shift by +2)

Step 2: Apply the same pattern of shifts to "SINGAPORE":

- S → U (shift by +2)
- I → G (shift by -2)
- N → P (shift by +2)
- G → E (shift by -2)
- A → C (shift by +2)
- P → N (shift by -2)
- O → Q (shift by +2)
- R → P (shift by -2)
- E → G (shift by +2)
Thus, the code for SINGAPORE is "UGPECNQPG".

We are given that 'SUN' is written as 'RWK' and 'MOON' is written as 'LQLK'. We need to determine the pattern from the given codes.

- 'S' is coded as 'R', 'U' is coded as 'W', and 'N' is coded as 'K'.

- Similarly, 'M' is coded as 'L', 'O' is coded as 'Q', and 'N' is coded as 'K'.

By analyzing these, we see that each letter in the word is replaced by a letter that follows a consistent pattern of shifts. Following the same pattern, the word 'STAR' will be written as 'RVXV'.

Thus, the correct answer is .

We are given that "REASON" is encoded as "TDDQSK". Let's analyze the pattern used for encoding: The shifting pattern alternates: +2, -1, +3, -2, +4, -3. Now, applying the same rule to "PRAYER": Thus, "PRAYER" is encoded as "RQDWIO", corresponding to option (b).
