In a certain code language, the word "CAUGHT" is written as the number code "125679" and the word "HEN" is written as "740". Using the same letter–digit pattern, how will the word "TAUGHT" be written in that code language?

Introduction / Context:
This coding and decoding problem tests your ability to identify a consistent mapping between letters of the alphabet and digits. You are given how two English words are written in code, and you must extend exactly the same pattern to a third word. Such questions appear frequently in bank exams, SSC, and other aptitude tests under verbal reasoning or coding–decoding.

Given Data / Assumptions:

• "CAUGHT" is coded as "125679".
• "HEN" is coded as "740".
• The code for "TAUGHT" must follow exactly the same letter–digit correspondence.
• The mapping from each letter to its digit is consistent wherever that letter appears.

Concept / Approach:
The key idea is that each letter is replaced by a single fixed digit. Once we know which digit stands for which letter from the given words, we simply apply the same mapping to the new word. There is no need for arithmetic with the digits; it is a direct substitution scheme.

Step-by-Step Solution:
Step 1: Write CAUGHT under its code 125679. C A U G H T 1 2 5 6 7 9 So C → 1, A → 2, U → 5, G → 6, H → 7, T → 9. Step 2: Use HEN → 740 to confirm and extend. H E N 7 4 0 We already had H → 7, which matches. Now we also get E → 4 and N → 0. Step 3: Now encode TAUGHT using this mapping. T → 9, A → 2, U → 5, G → 6, H → 7, T → 9. Step 4: Write the digits together in order: 9 2 5 6 7 9 → 925679.

Verification / Alternative check:
Check that every letter used in the new word already has a defined digit: T, A, U, G, H all appear in CAUGHT, so their codes are firmly fixed. There is no contradiction between CAUGHT and HEN, which confirms that our letter–digit dictionary is consistent.

Why Other Options Are Wrong:
Options "952679", "925697", and "952697" all scramble one or more digits. They do not keep the exact order T-A-U-G-H-T → 9-2-5-6-7-9. In a pure substitution code, the order of letters must translate to the same order of digits.

Common Pitfalls:
A common mistake is to focus only on the first word, ignore the second, and then guess the pattern. Another error is to rearrange digits or to average or add them. In this type of question, each letter maps to a unique digit and the positions must remain aligned.

Final Answer:
Therefore, in that code language, "TAUGHT" is written as 925679.
