In a certain code language, the word DEMONSTRATE is written as ETARTSNOMED by reversing all its letters. Using the same coding pattern, how is CORRUPT written in that code?

Introduction / Context:
This analogy question is based on a simple coding rule applied to English words. The given example shows how DEMONSTRATE is written in code, and we must detect the rule and then apply it to another word, CORRUPT. Questions like this are common in reasoning tests and measure your ability to recognise and manipulate patterns in strings of letters.

Given Data / Assumptions:
The word DEMONSTRATE becomes ETARTSNOMED in the code language. We must find the coded form of CORRUPT. All letters are kept the same, only their order changes. No extra letters are added and none are removed.

Concept / Approach:
When a coded word uses exactly the same letters as the original but in reverse order, the natural suspicion is that the rule is reversal of the entire string. Therefore, we need to check whether ETARTSNOMED is simply the original word DEMONSTRATE written backwards. If it is, then the same reverse operation must be performed on CORRUPT to find its coded form.

Step-by-Step Solution:
Step 1: Write DEMONSTRATE normally and then in reverse. Normal order: D E M O N S T R A T E. Reversed order: E T A R T S N O M E D. Step 2: Compare the reversed form to the code. The reversed form ETARTSNOMED matches the given coded word exactly. Step 3: Conclude the coding rule. The code for any word is obtained by writing all its letters in reverse order. Step 4: Apply this rule to CORRUPT. Normal order: C O R R U P T. Reverse the sequence of letters. Reversed order: T P U R R O C. This gives us the coded form TPURROC.

Verification / Alternative check:
To verify, we can reverse TPURROC again. Writing it backwards, we obtain CORRUPT, which is the original word. This confirms that the transformation is perfectly reversible and is indeed a full reversal of the letter order. The same rule works consistently for both DEMONSTRATE and CORRUPT, which means our identified pattern is correct and stable.

Why Other Options Are Wrong:
ORCRUPT rearranges some letters but does not represent the exact reverse of CORRUPT. ROCRTPU is a jumbled version and cannot be obtained by simply reversing CORRUPT. ROCRUPT also places letters in a different order and breaks the strict left to right reversal rule. CTRUPRO is another unrelated arrangement that does not correspond to the original word written backwards.

Common Pitfalls:
A frequent error is to assume that a more complicated coding rule is in use, such as swapping in pairs or shifting letters, when in fact a simple full reversal is enough. Another mistake is to reverse only part of the word, such as the first or last four letters, instead of the entire string. To avoid such mistakes, always check whether a complete reversal reproduces the given code exactly, and then apply that same clear rule to the new word in a careful, step by step manner.

Final Answer:
Using the same reverse coding pattern, CORRUPT is written as TPURROC in the code language.
