If the second half of the given series is reversed, then what will be the eighth term from the right? 9$YX8N6OLBUJZT@1QFD%
F
Reasoning Series Rearrangement Solution
This question asks us to analyze a given series of characters and symbols. We need to perform a specific operation on the series – reversing its second half – and then identify a particular element based on its position from the right end of the modified series.
Analyzing the Original Series
The original series is: 9$YX8N6OLBUJZT@1QFD%
Let's count the total number of terms in the series:
- 9
- $
- Y
- X
- 8
- N
- 6
- O
- L
- B
- U
- J
- Z
- T
- @
- 1
- Q
- F
- D
- %
There are a total of 20 terms in the series.
Dividing the Series into Halves
Since there are 20 terms, the series is divided into two equal halves of 10 terms each.
- First Half: The first 10 terms are 9$YX8N6OLB
- Second Half: The next 10 terms are UJZT@1QFD%
| Half | Terms |
|---|---|
| First Half (1-10) | 9$YX8N6OLB |
| Second Half (11-20) | UJZT@1QFD% |
Reversing the Second Half
The problem states that the second half of the series is reversed. Let's take the second half and write its terms in reverse order.
Original Second Half: UJZT@1QFD%
Reversed Second Half: %DFQ1@TZJU
Forming the New Series
Now, we form the new series by keeping the first half as it is and appending the reversed second half to it.
- First Half: 9$YX8N6OLB
- Reversed Second Half: %DFQ1@TZJU
The new series is: 9$YX8N6OLB%DFQ1@TZJU
Finding the Eighth Term from the Right
We need to find the eighth term from the right end of the new series. Let's list the terms from the right:
- % (1st from right)
- D (2nd from right)
- F (3rd from right)
- Q (4th from right)
- 1 (5th from right)
- @ (6th from right)
- T (7th from right)
- Z (8th from right) - Let me recheck my counting based on the structure UJZT@1QFD% becomes %DFQ1@TZJU. Rightmost is U, left is %. Okay, let's list from the *new* series: 9$YX8N6OLB%DFQ1@TZJU. Rightmost term is U.
Counting from the right end of the new series 9$YX8N6OLB%DFQ1@TZJU:
- U (1st from right)
- J (2nd from right)
- Z (3rd from right)
- T (4th from right)
- @ (5th from right)
- 1 (6th from right)
- Q (7th from right)
- F (8th from right)
The eighth term from the right in the new series is F.
Conclusion
After reversing the second half of the given series, the eighth term from the right is F.

Additional Information on Series Rearrangement
Problems involving the rearrangement of series, like the one discussed, are common in logical reasoning and aptitude tests. They test your ability to follow instructions precisely and manipulate sequences of elements. Key concepts include:
- Identifying Segments: Being able to correctly divide the series based on the given criteria (e.g., halves, thirds, specific number of terms).
- Performing Operations: Applying the required transformation to the specified segment (e.g., reversing, shifting, replacing).
- Reconstructing the Series: Combining the modified segment with the unchanged parts to form the new series.
- Positional Counting: Accurately finding the position of an element from a specified end (left or right). It's crucial to be careful when counting from the right end, starting with the last element as position 1.
Practice with different types of series (numbers, letters, symbols, or combinations) and various rearrangement rules can help improve speed and accuracy in solving these problems.
