If in a certain code, ‘POT’ is written as ATOP and ‘TRAP’ is written as APART, then how is ‘ARENA’ written in that code?

1. A. AARENA
2. B. AANREA
3. C. AANEAR
4. D. AANERA

Answer: D

Explanation

Let’s analyze the given coding pattern:

1. **POT is written as ATOP**:
– Original letters: P, O, T
– Coded letters: A, T, O, P
– It appears an ‘A’ is added at the beginning. The remaining letters (T, O, P) are the original letters (P, O, T) arranged in reverse order.
So, the pattern is: Add ‘A’ at the beginning, then write the original word’s letters in reverse order.

2. **TRAP is written as APART**:
– Original letters: T, R, A, P
– Coded letters: A, P, A, R, T
– Following the deduced pattern: Add ‘A’ at the beginning. Then write the original letters (T, R, A, P) in reverse order: P, A, R, T.
– Combining these: A + P A R T = APART. This matches the given code.

The pattern is consistent: Add an ‘A’ at the beginning of the word, then append the letters of the original word in reverse order.

Now, apply this rule to **ARENA**:
1. Add ‘A’ at the beginning: A
2. Original letters of ARENA (A, R, E, N, A) in reverse order: A, N, E, R, A.
3. Combine these: A + A N E R A = AANERA.

Therefore, ‘ARENA’ is written as AANERA. This question tests pattern recognition and coding-decoding skills.
