If the first half of the word INSTRUMENT is reversed, which of the following will be the fourth to the right of the third letter from the left end?
M
Understanding the Word Rearrangement Problem
The question asks us to perform a specific rearrangement on the word INSTRUMENT and then locate a letter based on its position in the new word. Let's break down the steps involved.
Step-by-Step Solution
The word given is INSTRUMENT.
- The word INSTRUMENT has 10 letters.
- The first half of the word is the first 5 letters.
- The second half of the word is the remaining 5 letters.
Original word: I N S T R U M E N T
First half: I N S T R
Second half: U M E N T
The question asks to reverse the first half of the word.
Reversed first half: R T S N I
Now, we combine the reversed first half with the original second half to form the new word.
New word: R T S N I U M E N T
Next, we need to find the third letter from the left end of this new word.
New word: R T S N I U M E N T
The third letter from the left is S.
Finally, we need to find the letter that is fourth to the right of this third letter (S).
Starting from S, we count four positions to the right:
R T S → 1st is N, 2nd is I, 3rd is U, 4th is M.
The letter fourth to the right of S is M.
Let's visualize the new word and the required positions:
R T S N I U M E N T
↑ Fourth to the right of S
↑ Third from the left
The letter we are looking for is M.
| Position from left | 1st | 2nd | 3rd | 4th | 5th | 6th | 7th | 8th | 9th | 10th |
|---|---|---|---|---|---|---|---|---|---|---|
| New word letter | R | T | S | N | I | U | M | E | N | T |
The third letter from the left is S (at position 3).
Counting four positions to the right of S (position 3): Position 3 + 4 = Position 7.
The letter at position 7 is M.
Therefore, the letter fourth to the right of the third letter from the left end of the new word is M.

|---|---|---|
| Word Segmentation | Dividing a word into parts (e.g., halves). | Dividing INSTRUMENT into INSTR and UMENT. |
| Reversal | Writing letters in reverse order. | Reversing INSTR to RT SNI. |
| Letter Positioning | Finding a letter based on its position from an end (left/right) or relative to another letter. | Finding the 3rd letter from the left, and the letter 4th to the right of it. |
Additional Information: Letter Sequencing and Puzzles
Questions involving word rearrangement and finding letters based on position are common in verbal reasoning tests. These questions assess your ability to follow instructions precisely and perform sequential operations. They often involve steps like reversing sections, swapping positions, or applying rules based on letter type (vowel/consonant) or position (odd/even). Practice with different types of rearrangement rules and positioning challenges can improve your speed and accuracy in solving such problems.
Always break down the problem into smaller, manageable steps: identify the word, understand the rearrangement rule, apply the rule to get the new sequence, and then locate the required letter based on the given position criteria.
