(C) 126432

(D) 123642

Answer 1

The first number when a terminal digit filing system is used is A) 126342.

Step-by-step explanation:

In a terminal digit filing system, the numbers are arranged in reverse order, starting from the last digit. In this case, we need to look at the last digit of each number to determine which one comes first. Let's compare the last digits of the given numbers:

1. A) 126342: The last digit is 2.
2. B) 145632: The last digit is 2.
3. C) 126432: The last digit is 2.
4. D) 123642: The last digit is 2.

Since all the numbers have the same last digit, we need to compare the second-to-last digits. The second-to-last digit of each number is 4. Therefore, the first number when a terminal digit filing system is used is A) 126342.
