Directions: Read the following arrangement of symbols, letters, and numbers carefully and answer the questions based on it. & F A # L K 4 $ 9 G P @ 8 B S M @ € 5 D % L β K 4 A 9 @ S W ¥ 6 B & 8 # J Step I: All the symbols, which are immediately followed by a letter, will be placed from extreme left end in the same order. Step II: If a letter is immediately followed by a symbol, then such letters are placed from extreme right end in the English Alphabetical order. Step III: All the numbers between the 7 element from the left end and 7 element from the right end are placed between the 11 and the 12 element from the left end in descending order. Step IV: The first ten elements of the arrangement from the left end are placed from extreme right end in the same order. Note: Step II is performed after the completion of Step I, similarly, Step III is performed after the completion of Step II, and so on. Which element is 7 to the left of 21 element from the left end after applying step IV in the given arrangement?

Answer
Correct Answer: €
Explanation
### Concept & Strategy
For questions asking to locate an element relative to another element's position, always compute the mathematical offset first to save time and reduce counting errors. If both directions are from the same end (e.g., "left of the ... from the left end"), subtract the values.
### Step-by-Step Solution
First, we must determine the final arrangement by following all four steps meticulously.
**Initial Arrangement:**
& F A # L K 4 $ 9 G P @ 8 B S M @ € 5 D % L β K 4 A 9 @ S W ¥ 6 B & 8 # J
**Step I:** Symbols followed by a letter move left.
* Moving `&`, `#`, `%`, `β`, `@`, and `#` to the extreme left gives:
`& # % β @ # F A L K 4 $ 9 G P @ 8 B S M @ € 5 D L K 4 A 9 S W ¥ 6 B & 8 J`
**Step II:** Letters followed by a symbol move right in alphabetical order.
* Moving `P`, `M`, `W`, `B` to the extreme right as B, M, P, W gives:
`& # % β @ # F A L K 4 $ 9 G @ 8 S @ € 5 D L K 4 A 9 S ¥ 6 & 8 J B M P W`
**Step III:** Specific numbers move between the 11th and 12th elements.
* Extracting 4, 9, 8, 5, 4, 9, 6 (which are between the 7th left and 7th right elements) leaves `$` as the 11th and `G` as the 12th.
* Sorting descending and placing between `$` and `G` gives:
`& # % β @ # F A L K $ 9 9 8 6 5 4 4 G @ B S @ € D L K A S ¥ & 8 J B M P W`
**Step IV:** First ten elements move to the right end.
* Moving `& # % β @ # F A L K` to the right end gives our final sequence:
`$ 9 9 8 6 5 4 4 G @ B S @ € D L K A S ¥ & 8 J B M P W & # % β @ # F A L K`
**Finding the Target Element:**
* The question asks for the element 7 to the left of the 21st element from the left end.
* Mathematically simplify the position: $21 - 7 = 14$th element from the left end.
* Counting 14 elements from the left in our final sequence:
1:`$`, 2:`9`, 3:`9`, 4:`8`, 5:`6`, 6:`5`, 7:`4`, 8:`4`, 9:`G`, 10:`@`, 11:`B`, 12:`S`, 13:`@`, 14:`€`.
### Exam Strategy & Shortcut
When asked for an element "X to the left of Y from the left end", always perform the arithmetic first. By doing $21 - 7 = 14$, you only need to count from the left end once, saving precious time and preventing miscounts during backtracking.
### Common Pitfall
A frequent error is recounting the elements incorrectly by accidentally skipping symbols like `@` or `€` when scanning the text quickly. Touch or point to each element as you count to exactly 14.
### Final Answer
Therefore, the correct answer is **€**.
