Final answer:
The value of X24 divided by Y13 cannot be determined based on the given information.
Step-by-step explanation:
If the entries of A + B are represented by Xi and the entries of A - B are represented by Yi, we can write the equation for X24 as X24 = a24 + b24 and the equation for Y13 as Y13 = a13 - b13, where aij and bij are the entries of matrices A and B respectively.
So, the value of X24 divided by Y13 is (a24 + b24) / (a13 - b13).
Since we don't have any information about the specific entries of matrices A and B in this question, we cannot determine the exact value of X24 / Y13. Therefore, none of the given options a, b, c, or d can be the correct answer.
