I believe we live in the Cenozoic era

It's kinda tough, since we don't know the actual numerical locations of the points, only an approximate picture.
The big ball has 11 times the mass of the small ball, so the small ball is 11 times as far from the barycenter as the big ball is.

The question ask to calculate and choose among the following is the distance of the microphone from the left - most speaker in order to pick up the loudest sound and the best answer would be letter C. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications
