Understanding the problem:
To solve this problem, we need to find the original number. The problem states that when 12 is added to this number, it becomes nine-eighth of the original number.

Solving the problem:
Let's assume the original number is x.
When 12 is added to x, we get x + 12.
According to the problem, x + 12 = 9/8 * x.

Calculating the original number:
Let's solve for x in the equation x + 12 = 9/8 * x.
8(x + 12) = 9x
8x + 96 = 9x
96 = 9x - 8x
96 = x
So, the original number is 96.

Finding 12.5% of the original number:
12.5% of 96 can be calculated as:
(12.5/100) * 96 = 0.125 * 96 = 12
Therefore, 12.5% of the original number (96) is 12, which corresponds to option A.
