Examples of problems?

Hi @brian-ai-6899,

Here’s an example for you:

Problem:
A $14$‑digit number $666666,XY,444444$ is a multiple of $26$. If $X$ and $Y$ are both positive, what is the smallest value of $X + Y$?

Answer Choices:
A. 3
B. 4
C. 9
D. 14
E. None of the above

Solution:
Since $1001$ is a multiple of $13$, $111111 = 111 \times 1001$ is also a multiple of $13$. It follows that both $666666$ and $444444$ are multiples of $26$.
Therefore, $XY$ must be divisible by $13$.
Smallest $X + Y = 1 + 3 = 4$.

Correct Answer: B
