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?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 6
Reversing a number writes its digits in the opposite order, so the first digit becomes the last. The new numbers are then compared.
135 → 531
269 → 962
667 → 766
581 → 185
783 → 387
In ascending order: 185, 387, 531, 766, 962. The second-largest is 766, and its unit digit is 6.
