Study the following five numbers and answer the question given below:

135 269 667 581 783

What will be the last digit (unit place) of the second-largest number when they are arranged in ascending order after reversing the positions of the digits within each number?

6

The correct answer is Option (2) → 6

1. Reverse the digits of each number

First, we reverse the positions of the digits for each of the given numbers:

• $135 \rightarrow \mathbf{531}$
• $269 \rightarrow \mathbf{962}$
• $667 \rightarrow \mathbf{766}$
• $581 \rightarrow \mathbf{185}$
• $783 \rightarrow \mathbf{387}$

2. Arrange the reversed numbers in ascending order

Now, we arrange these new numbers from smallest to largest:

1. $185$
2. $387$
3. $531$
4. $766$ (Second-largest)
5. $962$ (Largest)

3. Identify the unit digit of the second-largest number

The second-largest number in the sequence is $766$.

The last digit (unit place) of $766$ is $6$.
