Question:

Refer to the given letter, number and symbol string and answer the question that follows.
(Left) * 5 U £ 2 W @ 3 K 9 + \# 6 M & 4 A a 5 G 8 7 B % R O (Right)
If the sequence of the middle nine elements in the given string is reversed, then which of the following will be seventh to the right of the twenty-first element from the right end?

Show Hint

A phrase like "Xth to the right of Yth from the right end" is equivalent to the (Y-X)th element from the right end. Similarly, "Xth to the left of Yth from the left end" is the (Y-X)th from the left end.

The Correct Option is A

Solution and Explanation

Step 1: Understanding the Question:
We need to perform two operations on the given string. First, reverse the middle nine elements. Second, find a specific element based on its position from the right end.
Step 2: Detailed Explanation:
Part 1: Reverse the middle nine elements.
The original string has 25 elements. The middle nine elements will be from the 9th to the 17th position. Number of elements to leave from the start = \((25 - 9) / 2 = 16 / 2 = 8\). The first 8 elements are: * 5 U £ 2 W @ 3 The middle 9 elements (from 9th to 17th) are: K 9 + \# 6 M & 4 A The last 8 elements are: a 5 G 8 7 B % R O Now, we reverse the middle 9 elements: Original middle: K 9 + \# 6 M & 4 A Reversed middle: A 4 & M 6 \# + 9 K The new string becomes: * 5 U £ 2 W @ 3 A 4 & M 6 \# + 9 K a 5 G 8 7 B % R O
Part 2: Find the required element.
The question asks for the "seventh to the right of the twenty-first element from the right end". This can be calculated as a single position from the right end: Position = (21st from right) - (7 to the right) = 14th element from the right end. Now, let's count the 14th element from the right in our new string. New String: * 5 U £ 2 W @ 3 A 4 & M 6 \# + 9 K a 5 G 8 7 B % R O Counting from the right (O is 1st): 1st: O 2nd: R 3rd: % 4th: B 5th: 7 6th: 8 7th: G 8th: 5 9th: a 10th: K 11th: 9 12th: + 13th: \# 14th: 6
Step 3: Final Answer:
The 14th element from the right end of the modified string is 6.
