If 'PEN' is coded as 'QFO', what is the code for 'BOOK'?
Step 1: Identify the pattern in the code. The word 'PEN' is coded as 'QFO'.
Step 2: Notice that each letter in 'PEN' is shifted by +1 in the alphabet: 'P' becomes 'Q', 'E' becomes 'F', and 'N' becomes 'O'.
Step 3: Apply the same +1 shift to the letters in the word 'BOOK'.
Step 4: Shift 'B' to 'C', 'O' to 'P', 'O' to 'P', and 'K' to 'L'.
Step 5: Combine the shifted letters to get the final code for 'BOOK', which is 'CPPL'.
Letter Shifting – The question tests the ability to recognize a simple Caesar cipher where each letter is shifted by a fixed number of positions in the alphabet.
