None of the answers can be answered by elementary school knowledge. I told you to answer them in elementary school. This is a clumsy question.

Second Number-First Number = Difference

Let's talk about their differences first, because the first number is increased by 100000. If we subtract this 100000, the difference will be added to 100000 (because subtraction will add 100000), and the second number will be 100000.

The formula is (250461+10000-1)/9 = 38940.
