If in a certain code, ‘POT’ is written as ATOP and ‘TRAP’ is written as APART, then how is ‘ARENA’ written in that code?
Answer & explanation
Answer: (d) AANERA
Each word is reversed and an A is put in front: POT → TOP → ATOP, and TRAP → PART → APART. ARENA reversed is ANERA, so the code is AANERA.
- POT reversed is TOP; with A in front it is ATOP, which matches.
- TRAP reversed is PART; with A in front it is APART, which matches.
- ARENA reversed is ANERA; with A in front it is AANERA.
Remember · When a code looks like a real word, check for reversal plus a fixed added letter.
