To encode a word, take its letters in pairs and reverse the order within each pair. For example, LAMP becomes ALPM. How is PLAN encoded?
Correct answer: A. LPNA
- A. LPNA
- B. PLNA
- C. LNPA
- D. APNL
Explanation
PLAN is divided into the pairs PL and AN. Reversing each pair gives LP and NA, so the code is LPNA.

About Coding and Decoding
Coding and decoding questions replace letters, numbers, words or symbols with another pattern and ask you to identify the rule or decode a new item. Methods include alphabet positions, shifts, reversals, substitution, rearrangement, numerical values and separate rules for different parts of a code.
