Explanation
Try Plugging In.
If there are 10 cats at the beginning of the day, then there are 11 dogs; at the end of the day, there would be 15 cats and 15 dogs.
In this case, Quantity A and Quantity B are equal. Eliminate choices (A) and (B).
However, there could be 20 cats and 22 dogs at the beginning of the day; then there would be 25 cats and 26 dogs at the end of the day.
In that situation, Quantity B is greater; eliminate choice C. Only choice D remains.
