Step 1: Understanding the Question:
This is a coding-decoding problem using the "Atbash" cipher, where the alphabet is reversed (A=26, Z=1).
Step 2: Detailed Explanation:
The rule is: (text{Position of new letter} = 27 - text{Position of original letter}).
Decoding "RMWZR":
- R (18) (rightarrow 27 - 18 = 9) (I)
- M (13) (rightarrow 27 - 13 = 14) (N)
- W (23) (rightarrow 27 - 23 = 4) (D)
- Z (26) (rightarrow 27 - 26 = 1) (A)
- R (18) (rightarrow 27 - 18 = 9) (I)
Word 1: INDIA.
Decoding "RH": R (rightarrow) I, H (8) (rightarrow 27 - 8 = 19) (S). Word 2: IS.
Decoding "NB": N (rightarrow) M, B (rightarrow) Y. Word 3: MY.
Decoding "XLFMGIB": X (rightarrow) C, L (rightarrow) O, F (rightarrow) U, M (rightarrow) N, G (rightarrow) T, I (rightarrow) R, B (rightarrow) Y. Word 4: COUNTRY.
Step 3: Final Answer:
The decoded sentence is "INDIA IS MY COUNTRY".
